I would like to know if I am the only one having a terrible experience using the 5 Ghz band on the Flint using the latest stable firmware…? Connections keep dropping, signal is not good, overall it is a terrible experience.
The 2.4 Ghz band seems to be working fine however. Anyone else having the same issues as me?
As a follow up, it tried many of the suggestions proposed in this thread. The country code was checked and was correct, WiFiman was downloaded to verify any potential problems etc. I tried the latest beta firmware, I tried 4.4.6, 4.2.3. / The only firmware that is rock solid regarding the WiFi signal is 4.2.1.
So here it is, I’m back on 4.2.1 since it is the only firmware that gives me a stable internet connection. I forgot to mention that I’m also using this router as a “VPN router” using Wireguard. If I were to guess, I would say that from 4.2.1 to 4.2.3 and beyond, the WiFi driver changed. I read a previous post regarding someone else who had to do as I did and revert back to 4.2.1. This is not normal.
I have WiFiman running right now. Using firmware 4.2.1, my router is still using channel #36 using the 5180MHz/80. So the router no matter the firmware is using the same channel and frequency so it is not a congestion problem… My best guess would be a driver / software issue… Hope this could help. WiFi Signal on either 2.4 and 5 GHz is rock solid since moving to 4.2.1. The problem never was with 2.4 Ghz by the way, it always was with the 5Ghz band.
Not sure if it matters but my WiFI configs where using WPA-2 and WPA-3 on the 2.4 band. On the 5Ghz band I was only using WPA-3.
Thank you everyone for helping out, it is much appreciated. This is a little update on the situation…
After spending many days and weeks pulling my hair out trying to figure out how to fix this issue, I think I might have found part of the problem…
As you know I been changing firmware going up and down trying to find something that would give me a stable 5GHz connection. All in all, some 4.x firmware where better than others but nothing rock solid. I decided to upgrade once again to the latest 4.4.6 version. What I did next was to remove WPA-3 from the settings and only use WPA2-PSK on both the 5Ghz band and the 2.4Ghz band. That seems to have fixed the major issues I was having. I also manually configured the 5GHz band to use channel 161. All in all, as of this morning, my 5 GHz signal has been rock solid. It seems that some adapters do not play nice with WPA-3. I will keep you all posted and see if this stability last. I’m also wondering how my future Flint2 will handle this with the default options enabled…
Thanks again for all who have tried to help me fix this. An update will follow in a weeks time.
Cripes; this isn’t the first time I’ve heard of WPA3 being the root cause. I wouldn’t worry too much re: WPA2 v WPA3 if you’re looking for ‘top notch’ Wi-Fi security; Dragonblood renders it all moot. It’d be better to setup up WG + PSK on all devices in the subnet.
