TV Won’t Connect to 5G Wifi (Causes and How to Fix)

If you’re like me, you’ve probably experienced the frustrations of trying to connect your TV to your 5G wifi. I was recently in this situation and after hours of research and trial and error, I finally figured out how to fix it. In this blog post, I’ll be sharing what I discovered, the causes of this issue, and the tips and tricks I used to get my TV connected to the 5G wifi. Hopefully, this will provide helpful information to anyone else struggling with the same issue!

To figure out why the TV won’t connect to your 5G Wifi, ask yourself, “Is the Wifi connecting with other devices but not the TV?”

If you answered ‘yes,’ then it’s safe to assume there’s nothing wrong with the modem or router.

The alternative is that the problem has to do with the TV itself. 

Improper WLAN ChannelOlder TVs may only support 2.4 GHz WLAN channels, leading to slower speeds and connection dropouts.Upgrade to a TV that supports 5 GHz Wifi, or use a 2.4 GHz Wifi connection.
Too Many Devices Connected to NetworkRouter struggles to handle all connected devices, resulting in weak or spotty signal on the TV.Reduce the number of devices connected to the network or prioritize the TV’s connection in router settings.
Poor Wifi SignalTV’s power cycle configuration may cause it to fail in detecting Wifi signal.Restart the TV or perform a hard reset to restore connectivity.
Electronic InterferenceDevices like cordless phones, microwaves, or baby monitors can interfere with Wifi signal.Keep TV and router away from such devices to minimize interference.
Incorrect DNS Server SettingsDNS server settings not configured correctly for a 5 GHz Wifi connection.Ensure that the TV’s DNS server settings are correctly configured.
GlitchesErrors or glitches in signal pathways can result in weak connection.Unplug the router and/or turn off the TV for a few minutes before turning them back on.
Hard ResetA factory reset may be required to resolve certain connectivity issues.Perform a factory reset according to the TV manufacturer’s instructions.

Improper WLAN Channel

The most common reason for this problem is that the TV doesn’t support the router’s wireless LAN (WLAN) channels.

This is because relatively older TVs are designed to support 2.4 G WLAN channels. Yet, they’re not designed to handle anything higher. Thus, you’re met with slower speeds and repeated connection dropouts.

Many Devices Are Connected to the Same Network

While the router is designed to handle several home devices, it can slow down when they’re all connected at the same time.

This goes double for TVs because of their larger sizes and different configuration than a laptop or smartphone. Hence, even if the network status says ‘connected,’ the signal strength can be spotty and weak, making it difficult to open up apps or stream videos.

Poor Wifi Signal

Due to the way TVs are configured, they sometimes suffer issues related to their power cycle. This can result in the device failing to detect a Wifi signal.

Many times, shutting down the TV and restarting it after several minutes should be enough. However, if it doesn’t work, you’ll have to do a hard reset. It’s more time-consuming, but it’s guaranteed to restore connectivity.

How to Connect My TV to 5G Wifi

So, now you’ve checked the specs of your TV and determined that it supports faster 5G Wifi. The next step is to figure out how to connect it to your wireless network.

You can either do this via an Ethernet cable or wireless. The one you opt for depends on the make and model of your TV, so check the user’s manual for more information.

Wireless Connection

To connect your TV set to a wireless 5G Wifi connection, follow these steps:

  1. Turn on the TV.
  2. Then, using the directional pad on the remote control, select ‘Settings,’ ‘General,’ then ‘Network.’
  3. Next, select ‘Open Network Settings’ and choose your desired Wifi network.
  4. Enter the network password when prompted.
  5. Finally,  choose ‘Done,’ then ‘OK.’

Wired Connection

Some TVs don’t have wireless capabilities. If this applies to your TV set, you can easily connect it to the router or modem via an Ethernet cable, as shown below:

  1. First, connect your Ethernet cable to the LAN port on the One Connect Box or the back of your TV set.
  2. Next, connect the other end to your router or modem, depending on your device.
  3. Turn on the TV and go to the Home screen.
  4. Use the TV remote to find and select ‘Settings,’ ‘General,’ then ‘Network.’
  5. Then, choose ‘Open Network Settings,’ choose ‘Wired,’ and finally, select ‘OK.’

How to Improve Your 5G Wifi Connection

Even though they’re the best-of-the-best, 5G Wifi connections can sometimes get spotty. This could be due to various reasons, including the location of your device, the layout of your home, or electronic interference.

So, in an effort to help you boost both your wired and wireless connections, we rounded up these handy tips. Take a look.

Reduce Electronic Interference

Electronic interference is one of the most common reasons behind an unstable Wifi connection.

To avoid this problem, try to place your TV away from devices, such as cordless phones, microwaves, or even audio baby monitors.

Also, keep all types of cordless devices away from the router because they have similar Wifi frequencies, which can disrupt signal strength.

Check the DNS Server Settings

Every multimedia device with internet access comes with Domain Name System (DNS) server settings. It’s through these settings that the device is able to enter the world wide web in the first place by converting domain names into internet IP addresses.

If your TV enables 5G Wifi, you have to make sure the DNS server settings are correctly configured.

Eliminate Glitches

Sometimes, the connection is weak due to an error or glitch in the signal pathways. So, if you notice your connection is acting up, the best way to fix it is to unplug the router from its power source for no less than 30 seconds.

This will help reset the router’s connection settings and eliminate unwanted devices that may have latched onto your network. It’s also the quickest way to interrupt malicious attacks, which can negatively affect your streaming experience.

You can also turn off the TV for a couple of minutes, then turn it back on again.

Try a hard reset

A hard reset involves completely resetting the TV to its factory defaults. Most TV models have specific instructions. However, if you have a Samsung TV here are the steps to follow:

To perform a factory reset:

  1. Head to Settings > General.
  2. Select Reset.
  3. Enter your PIN > then select Reset.

Note: If you didn’t change your PIN initially the code is 0000

Wrapping Up

Now, you know all there is to know about why your TV won’t connect to 5G Wifi and how to fix it. Remember, it all depends on the TV’s configuration.

If it doesn’t support 5G Wifi, there’s nothing you can do on that front. On the other hand, if it does, then the tips in this post are sure to keep your connection strong and stable.
