Problem with software version 05.80.35

[Alcides Andrade]

I have lg tv model 49UJ6525, last weekend the tv updated to version 05.80.35, but now I realized that I can no longer use the 5 GHz WIFI network, the network is disconnecting and connecting all the time. I did a test with the 2.4 Ghz network and it works normal, but I would like to use the 5GHz network.
Is it possible to solve this problem?

@Alcides Andrade It might be that the new update is making the 5G more sensitive to interference on channels. If you have a laptop or desktop that can access 5G WiFi, download the neat program "WiFiInfoView" from here:

and run it. Wait for a couple of minutes for it to settle down and pick up your close neighbours WiFi SSID's and check if any close ones are on your same 5G channel. I use channel 36 on mine, and see no interference.

If you don't have a manual for your router model, download one from the manufacturers site, check how to log in, and go to the settings, try changing the channel number to one that nobody else is using.

If you test it in the same room as the TV, this will give you a better picture of what the TV will being getting.

@td47 thanks for answering.
I tried to do as you suggested, but there is no other 5Ghz network on the same channel that my network is on.
I realized that after about 20 minutes it seems that the TV can stay connected to the 5Ghz network, but it is not cool to wait this time every time you turn on the TV

@Alcides Andrade What does the signal strength show for the 5G, in the TV room, on the WiFiInfoView program? Does it vary much over time?

[Alcides Andrade]

@td47 The signal is stable, but the router is close to the TV, in the same environment.
Even contacting LG support they did not give me any solution.

I managed to fix the problem. I discovered that the problem was the name of my wifi that contained special characters, I removed those characters and it worked.
The wifi name changed from "Kameouse-A-5G" to "KamehouseA5G".

@Alcides Andrade Thanks for the useful feedback. I had read about that "problem" too, somewhere on this forum, but it is the first time I have seen it confirmed.

I assume that all your OTHER devices on your home network have been fine with the special characters?  I find it very odd, that the firmware and WiFi internal card can be written to work for a time, then drop out the 5G. Did this work for longer on the 2.4G, or were you not able to test  that?  Actually a hyphen (dash) character is not all that special, and I have seen SSID names with spaces in, that work, so it is a bit of a subtle "bug" (as it is part of a standard character set in many languages). If it had been a Tilde (~) then OK, a bit more obscure, but not impossible to code for surely?

Glad you got it working, you post may be useful to others, thanks again.

@td47 After the firmware update, only the 5Ghz network had a problem with using the hyphen. The 2Ghz network continued to function well even with a hyphen in the network name.
I really believe that it is a bug in the firmware version, however, it is possible to continue using the device normally just by making this change to the SSID of the 5Ghz network.
An easy problem to solve but difficult to discover .....
