TV, Wi-Fi, router and printer questions

Restart the Roku and your router, then re-enter the Wi-Fi password in Settings, Network. If it still fails, move the router closer or try the 2.4 GHz band, and check that the Roku software is up to date.

Go to Settings, System, Advanced system settings, Factory reset and follow the prompts. If you cannot reach the menu, hold the small reset button on the device for about 20 seconds until the light flashes.

Usually it is weak power, such as a USB port on the TV that does not supply enough. Use the included wall adapter, check the cable, and update the software. A failing device may need replacing.

A full storage, too many background apps or weak Wi-Fi are the usual causes. Clear app caches, uninstall apps you do not use, restart the stick, and plug it into the wall adapter instead of the TV's USB port.

Go to Settings, Applications, Manage Installed Applications, choose an app, then select Clear cache. Do this for apps that are slow or freezing. Clear data only if you are fine signing in again.

Go to Settings, My Fire TV, Reset to Factory Defaults. This erases your apps and sign-ins. If the screen is not usable, hold the Back and Right buttons on the remote together for about 10 seconds.

Replace the batteries first, then unplug the stick for a minute and restart it. If it still does not respond, hold the Home button for 10 seconds to re-pair, or use the phone app as a temporary remote.

A weak Wi-Fi signal or a different network than your phone is the usual cause. Restart the Chromecast and router, move the router closer, and make sure both devices are on the same Wi-Fi network.

Hold the button on the device for about 25 seconds until the light blinks, then release. On Google TV models, you can also reset from Settings, System, Reset. You will need to set it up again.

Open Settings, then look for Support, About or System, and choose Software update. Turn on automatic updates if offered. The TV must be connected to the internet, and the menu names vary by brand.

Press the Home button, open Apps, then Settings, and turn on Auto Update. You can also highlight an app, hold Enter, and choose Update. Menu names can differ slightly by model year.

Open the LG Content Store, go to your apps list and choose Update if one is available. LG TVs usually update apps automatically when connected to the internet, and firmware updates are in Settings, Support.

Old TVs stop getting app updates, so some services drop support. Restart the TV, update its software, and reinstall the app. If your TV is more than about eight years old, a streaming stick is a cheap fix.

Check your internet speed, restart the TV and router, and update the app. Clearing the app's data or reinstalling it often helps. If it persists, a streaming stick may run better than an aging TV.

Unplug the TV for a minute to clear memory. On many models you can also clear a single app's cache or data in Settings, Apps. Menu names vary by brand, such as Samsung, LG, Sony or Vizio.

A full storage, too many background apps or old software can slow it down. Restart the TV, update the software, remove unused apps, and use a wired or strong Wi-Fi connection.

Open Settings, then Network, choose your Wi-Fi network and enter the password. If it will not connect, restart the TV and router, and try moving the router closer or using an Ethernet cable.

Restart the TV and router, check the password, and make sure the router is not blocking new devices. Try turning the TV off at the wall for a minute, and move the router closer for a test.

The input source is probably wrong, or a cable is loose. Press Input or Source on the remote, reseat the HDMI cable at both ends, and try another HDMI port. Check that the connected device is turned on.

HDMI ARC means Audio Return Channel. It lets one HDMI cable send TV sound to a soundbar or receiver, so you can use one remote and one cable. Plug into the port labeled ARC or eARC.

eARC is a newer version of ARC with more bandwidth. It supports higher quality audio formats like Dolby Atmos in full quality. You need an eARC TV, an eARC soundbar and a high speed HDMI cable.

For 4K at 60 frames per second, use a cable labeled High Speed or Premium High Speed. For 4K at 120 Hz or 8K, look for Ultra High Speed. Most older cables work for basic 4K at 30 Hz.

Check that the source is 4K, the HDMI cable is high speed, and you are using the TV's 4K-capable HDMI port. Some ports must have enhanced HDMI mode turned on in the TV settings.

It is motion smoothing that makes movies look unnaturally fast and smooth. Turn it off in the picture settings, where it may be called Motion Smoothing, TruMotion or Auto Motion Plus. Many TVs have a Filmmaker mode.

Open picture settings and find options like Motion Smoothing, TruMotion, MotionFlow or Auto Motion Plus, then set it to off. Choosing Movie or Filmmaker picture mode often turns it off at once.

Movie, Cinema or Filmmaker mode is usually the most accurate. Standard works well for daily viewing. Vivid mode looks bright in stores but often oversaturates colors and can tire your eyes.

Check the picture mode, backlight and contrast settings, and try a different HDMI cable. If the source device has an HDR or color range setting, set it to match the TV. Resetting picture settings can also help.

Lip sync problems are often caused by a soundbar or Bluetooth speaker adding delay. Check for an audio delay or AV sync setting on the TV or soundbar and adjust it. Try a wired connection if possible.

Check the volume limits and the audio output setting, and try turning on a dialogue or night mode. Built-in TV speakers are small, so a soundbar is the most effective fix for weak sound.

Usually yes. TV speakers are small and thin, while even an inexpensive soundbar makes dialogue clearer and sound fuller. For the best sound, a soundbar with a subwoofer or a separate speaker system works better.Try: Repair or replace calculator

The simplest way is an HDMI cable from the TV's ARC or eARC port to the soundbar. You can also use an optical cable or Bluetooth. Then set the TV's audio output to the soundbar.

Check that the TV's audio output is set to HDMI ARC or optical, the correct input is selected on the soundbar, and the cable is in the ARC port. Turn on HDMI-CEC if your TV has it.

HDMI-CEC lets devices connected by HDMI control each other, such as turning on a soundbar with the TV. Brands name it differently, such as Anynet+, Bravia Sync or Simplink. Turn it on in the TV settings.

Loose cables, Bluetooth interference or an HDMI ARC glitch are common causes. Try a different HDMI cable, use the ARC port, restart both devices, and update the soundbar's firmware.

Check the manual for your model, but many soundbars reset by holding a button combination, often Volume Down and Power or a dedicated reset button, for several seconds. This restores factory settings.

Many newer TVs support Bluetooth audio, but not all do. Look for Bluetooth in the TV's sound settings. If your TV lacks it, a Bluetooth transmitter plugged into the audio output can add it.

As a rough guide, sit about 1.5 times the screen diagonal away for a 4K TV. A 55 inch TV suits about 6 to 8 feet, and 65 inch suits about 8 to 10 feet. Personal preference matters too.

OLED screens light each pixel individually, giving deep blacks and wide viewing angles. QLED uses an LED backlight with a quantum dot layer and is usually brighter. OLED suits dark rooms, QLED suits bright ones.

Yes, if you can find wall studs and follow the mount's instructions. Check the TV's VESA pattern and weight limit. For larger TVs, drywall without studs or brick walls, ask a professional installer.

TV mounting by a professional usually costs around $75 to $250, depending on TV size, wall type and whether cables are hidden in the wall. The mount itself may be extra.

Blinking lights are error codes that vary by brand. Often it points to a power supply or main board issue. Unplug the TV for a minute, then check your manual for the pattern. A repeating count usually matters.

TV repair usually costs around $100 to $350, depending on the part. Power boards and main boards are common fixes. Panel replacements often cost more than the TV is worth.

Yes, using an HDMI cable. Set the TV to Game or PC mode for sharper text and lower delay. Large TVs have lower pixel density than monitors, so text may look less crisp up close.

Use AirPlay if your TV supports it. Open Control Center, tap Screen Mirroring and pick your TV. Otherwise use a Lightning or USB-C to HDMI adapter. Both devices need to be on the same Wi-Fi network.

Use the Cast, Smart View or Screen Cast option in quick settings, then choose your TV. Both devices should be on the same Wi-Fi network. A USB-C to HDMI adapter also works on many phones.

A streaming stick is often faster and gets updates longer than a TV's built-in system. It is a cheap way to refresh an older smart TV. A newer TV's built-in apps work fine for many people.

Evening is when many neighbors stream and use the internet, which can congest your provider's network and crowd nearby Wi-Fi channels. Try the 5 GHz band, a wired connection, or ask your provider about local congestion.

This points to Wi-Fi interference, distance or an old router rather than your internet plan. Move closer, switch to 5 GHz, change the channel, or upgrade your router or add a mesh system.

For general use, 25 to 100 Mbps per person is plenty. Streaming 4K video needs about 25 Mbps per stream. What matters is that your plan covers all devices running at the same time.

Mbps means megabits per second and is how internet speed is sold. MBps means megabytes per second and is how file downloads often show. One megabyte is 8 megabits, so 100 Mbps is about 12.5 MBps.

Ping is the time in milliseconds it takes for a signal to travel to a server and back. Lower is better. Under 50 ms feels responsive for gaming and video calls, and wired connections usually have lower ping.

Under 50 ms is good and under 20 ms is excellent for most online games. Above 100 ms you may notice lag. A wired Ethernet connection usually gives lower and steadier ping than Wi-Fi.

Packet loss is when data sent over your network never arrives, causing lag and drops. Restart your modem and router, use Ethernet, and check cables. If it continues, contact your provider.

Wi-Fi limits, old equipment, busy times and many devices can all lower speed. Test with a cable to the modem. Advertised speeds are also maximums, so you may see about 80 to 95 percent of them.

Most smart home gadgets only support 2.4 GHz, which has better range. Use 5 GHz for phones, laptops and TVs close to the router. Many routers combine both under one name or let you split them.

Splitting them can help when a smart device refuses to join. Otherwise a combined name lets your devices pick the best band automatically. You can combine them again after the setup finishes.

Wi-Fi 6E is Wi-Fi 6 with an added 6 GHz band, giving more room and less interference. It needs a 6E router and a 6E device. It works best at short range in crowded areas.

Buying your own router usually saves money over rental fees, which can add up to well over $100 a year, and often gives better performance. Check that it is compatible with your provider before you buy.

Not required, since a combined gateway works fine. Separate units let you upgrade the router without changing the modem and often give better Wi-Fi. Many people prefer them in larger homes.

Connect the router to your modem with an Ethernet cable, power both on, and follow the setup app or web page. Set a unique network name and a strong password, then reconnect your devices.

Log in to the router settings or app and look for Firmware, Update or Administration. Many modern routers update automatically. Do not turn the router off while an update runs.

Find the small reset button on the back, then hold it with a paperclip for about 10 to 30 seconds. This erases your custom settings, so you will need to set up your Wi-Fi name and password again.

Lights vary by model, but a steady green or white usually means connected. Red, orange or a blinking light often points to no internet or a startup issue. Check your router's manual for the exact meaning.

A red light usually means the router has lost its internet connection or has a hardware problem. Check cables, restart the modem and router, and see if your provider has an outage.

It usually means the modem is not getting a signal from your provider. Check that coax or fiber cables are tight, restart the modem, and check for an outage. If it persists, call your provider.

Your device is joined to the router, but the router has no internet. Restart the modem and router, check the cables, and look for an outage. If other devices work, the issue is on that one device.

On most phones and computers, open the network or Wi-Fi settings and look at the connection details. Your public IP shows by searching for what is my IP. Your router has a separate local address.

DNS turns website names into addresses. Changing to a public DNS can sometimes speed up browsing or fix errors. You can change it in your device's network settings or in your router.

A VPN encrypts your connection and routes it through another server. It can lower speed a little because of the extra distance and encryption. Quality VPNs usually have only a small effect.

Your router's app or admin page often shows connected devices and data use. Some routers have a traffic monitor. Streaming, game downloads and backups are the usual heavy users.

QoS stands for Quality of Service. It lets the router prioritize certain devices or activities, like video calls or gaming, so they keep working when the network is busy. You turn it on in the router settings.

A guest network is a separate Wi-Fi network for visitors that keeps them away from your main devices and files. Turn it on in the router settings and give it its own password.

Most home routers handle 20 to 50 devices, but speed drops as more are active at once. A newer Wi-Fi 6 router or a mesh system copes better with a smart home full of devices.

It is worth it for larger homes, multiple floors or thick walls where one router cannot reach everywhere. For a small apartment, a good single router is usually enough and costs less.Try: Repair or replace calculator

A two or three piece mesh system covers most homes. A rough guide is one node per 1,500 to 2,500 square feet, but walls and floors matter. Place nodes within good range of each other.

Place the main node by the modem and put other nodes about halfway between it and the weak area, with a strong signal to the main one. Keep them in the open rather than in cabinets.

No, most work wirelessly. But connecting nodes to the main router by Ethernet, called wired backhaul, gives faster and steadier speeds. It is worth doing if your home has network cables.

Use a mesh system or place extra wired access points on each floor. Put the main router in a central spot. A wired connection between units gives the best results.

Use AirPrint: open what you want to print, tap Share, then Print and choose a printer. The printer must support AirPrint and be on the same Wi-Fi network as your iPhone.

Open the item, tap the three dots or Share, choose Print and pick your printer. Android uses Mopria and the Default Print Service. Many printers also have a maker app that works well.

Place the page face down on the glass, or in the feeder, and use the scan button on the printer or the maker's scan app on your computer. Choose PDF for documents and save it to your device.

On iPhone, use the Notes or Files app's scan document tool. On Android, use the Google Drive scan option or the camera's document mode. Hold the phone steady on a flat, well lit page.

Check that the printer and computer are on the same network or connected by USB, and open the printer's scan software. Restart both devices, update drivers, and allow the app through your firewall.

High quality settings, large images and weak Wi-Fi slow printing. Choose Draft or Standard quality, use a USB or Ethernet cable, and restart the printer. Older printers are simply slower.

Clogged print heads, low ink in one color or a wrong paper setting are common causes. Run a nozzle check and head cleaning, replace low cartridges and make sure the paper type is correct.

Printers estimate ink by counting prints, not by measuring it, so warnings can come early. You can often keep printing until quality drops. Some printers will stop anyway and need a cartridge replaced.

Remove and reseat the cartridge, make sure the tape is removed and the contacts are clean, and restart the printer. Third-party cartridges can be rejected by some firmware, so check compatibility.

Open the printer's maintenance or tools menu, or its software, and choose Align Print Heads or Calibrate. The printer will print a test page and may ask you to scan it. Use plain white paper.

Open every access door and check for small torn bits, and look at the rollers. Turn the printer off, wait a minute and restart. Dust on the paper sensor can also cause false jam alerts.

Inkjet printers spray liquid ink and are good for photos and occasional printing. Laser printers use toner, print text faster and cost less per page, so they suit offices and heavy printing.

Laser printers are generally cheaper per page for text, and toner does not dry out. Refillable tank inkjets can also be very cheap to run. Ordinary cartridge inkjets cost the most per page.

If you print often, yes. Refillable tank printers cost more upfront but lower the price per page a lot. For rare printing, ink can dry out, so a laser printer may suit you better.Try: Repair or replace calculator

Ink in the print head nozzles dries when not used, causing streaks or blanks. Print a page every week or two to keep the nozzles clear, and leave the printer plugged in so it can self clean.

Yes. Many printers print from a phone, a USB drive or a memory card. Check your printer's features. Wireless printing from a phone through AirPrint or Mopria is the easiest.

Print a network configuration page from the printer's settings menu, or look in the Wi-Fi or network settings on its screen. You can also find it in your router's list of connected devices.

Download the latest driver from the printer maker's support site, using your exact model, and install it. On Windows, you can also check Windows Update. On Mac, updates come through system updates.

Look in the printer's setup or maintenance menu for Restore Defaults or Reset. On models without a screen, hold the Wi-Fi and cancel buttons for several seconds. Check the manual for your model.

Turn the printer on, open the cartridge door, wait for the carriage to move, remove the old cartridge and insert the new one until it clicks. Close the door and run an alignment if asked.

The cartridge may be the wrong model, a third-party cartridge the printer blocks, or a poor connection. Check the model number, clean the contacts and restart the printer.

Yes. A USB cable is often more stable and simpler than Wi-Fi and works with a single computer. Install the driver, plug in the cable and select the printer.

Check that the bulb's switch is on, the bulb is in Wi-Fi range and your router is working. Turn the bulb off and on, and try re-adding it in the app. Keep wall switches on.

Open the Alexa app, go to Devices, select your Echo and choose Change Wi-Fi network. Follow the prompts and enter the password. Make sure your phone is on the same network.

Restart the Echo and your router, then check your internet connection. Make sure the Wi-Fi password has not changed and the Echo is in range. If it persists, reset the device and set it up again.

Restart the speaker and router, check that the Google Home app shows it online and confirm the microphone switch is on. Make sure your phone is on the same Wi-Fi as the speaker.

A weak Wi-Fi signal at the door is the most common cause. Restart the doorbell and router, check the battery or power, and add a Wi-Fi extender or mesh node near the door if needed.

Battery life is usually several weeks to a few months depending on use and temperature. Cold weather and many motion alerts drain the battery faster, so a wired or plug-in setup is worth considering.

Many cameras offer live view for free but charge a monthly fee for cloud recording and extra features, often $3 to $15. Some models store video on a memory card instead.

Wired cameras are more reliable and don't need batteries, but installation is harder. Wireless cameras are easier to place, though they depend on Wi-Fi strength and battery or power. The choice depends on your home.

Weak Wi-Fi is the usual cause. Move the camera closer to the router, lower the video quality, or add a mesh node. Check that too many cameras are not sharing the same bandwidth.

Lower the motion sensitivity, set activity zones to ignore streets and trees, and turn on person detection if available. You can also set schedules for when alerts are active.

They can be, especially with weak passwords or old firmware. Use unique passwords, turn on two-factor sign-in, update firmware, and put smart devices on a guest or separate network.

Start with one ecosystem, such as Alexa, Google Home or Apple Home, and add a few devices like smart plugs and bulbs. Make sure your Wi-Fi is strong, then expand as you get comfortable.

Both are low power wireless standards for smart home devices that need a hub. Zigbee uses 2.4 GHz and Z-Wave uses a lower frequency with better range and less interference. Thread and Matter are the newer options.

Thread is a low power mesh network for smart devices that works with Matter. Devices relay signals to each other, making a reliable network. You need a Thread border router, like some speakers and streaming boxes.

No. A smart plug uses about 1 to 2 watts, which adds up to only a few dollars a year. They can save energy by turning off devices you forget.

Check the plug's maximum rating. Many are rated 10 to 15 amps, which can handle some devices, but heaters draw heavy power and can be a fire risk. Follow the maker's guidance and never exceed the limit.

Check that it is connected to Wi-Fi, the time zone is correct and no hold or away mode is active. Update the firmware and the app, and look at whether manual changes override your schedule.

Many smart locks connect through a bridge or hub rather than directly. Follow the maker's app to pair the lock and bridge, then connect the bridge to Wi-Fi. Keep the bridge within range of the lock.

An indoor or outdoor antenna picks up free local broadcast channels. Signal strength depends on your distance from towers. Run a channel scan in the TV's settings after connecting it.

Reposition the antenna near a window and higher up, then rescan channels in the TV settings. Distance from towers, trees and buildings affect reception. An amplified or outdoor antenna may help.
