Posted: Thu Jan 14, 2021 0:50 Post subject: 5GHZ channel missing on some devices... Stumped. SOLVED :*)
Router Netgear 7800
Firmware. DDWRT Brainslayer
Current Firmware R45420
Not sure when it stopped working for this device, but other 5ghz networks are showing, and the Modem my cable company provides the 5ghz is showing up.
For some reason the Netgear 5ghz doesn't show up in the one device, and I have pretty much basic settings and have tried different channels just to be sure.
The same channels I have tried using the cable company modem shows up fine so something isn't right in the Netgear.
Any thoughts on what I may try and tweak on the Netgear?

If you stand right next to the netgear, does your phone "see" the 5Ghz device? If so, try increasing the transmit power.
If not, then the 5Ghz signal is probably not being transmitted. Double check your settings.

The phone is fine connecting to 5ghz, only the one device. Thanks

Change your channel selection to unii 1 channels, most likely the gtv is region locked and can't see band 3 or unii 3 channels. This is very common in cheap shit driver/chips used in these low cost devices. Or ask GTV if they can unlock bands...otherwise you'll need root to change android is settings, and you'll need to research how to do that. _________________ FORUM RULES

Lol 😂 it cost a bomb.
I will give that a try, also realized but not sure it matters is I set up a static ip, may delete that and see if it matters.

@James Greystone, would you consider helping me so I might be able to have some more to discuss with BS the dev when I talk to him?
I would request of you to backup your settings in 45420 and then reset back to factory defaults, go back to 44715(will read as 44719 after installed) and re-enter all your settings again, manually (restoring a backup will spawn nvram gremlins), and then see if you still have the same issue with the wifi when set to AC/N mixed only?
If you do have the same issue, then I would say this is a client issue and would need to run some terminal emulator commands on the GTV to see what type of wifi drivers are installed and/or what wifi modes are supported by the chipset.
Mixed mode adds 802.11a support.
this is legacy standard supporting only up to 54mbps MCS connection rates. What is the GTV reporting right now for connection rate on 45420? If you are seeing this rate now, then I have no other conclusion that your rather expensive streaming box is using a shitty/cheap 802.11a wifi chipset. Otherwise if the rates are being reported as 866mbps then it means something else in the code is wrong and that's why I want to see what is happening at 44715 vs 44520... this may help us track down where the bug really is; which a few other users have now reported.
Just make sure the router and GTV are close enough to achieve full strength signals or it will be really hard to tell what's up. I'll have to google around for running shell commands in terminal emulator, as I'm no linux guru, to provide more troubleshooting steps depending on what you report back. This is going to get very interesting if you choose to help so I appreciate your contribution if you decide to help out All users. _________________ FORUM RULES
