Flint GL-AX1800 2.4 GHz can't connect

Firmware 2.308 Adguard Home running , VPN OpenVPN Client in use, Killswith enaged, VPN policy

In the past 24 hours 2.4GHz can not be accessed on LAN WiFi or Guest WiFi, can only use 5G network. ESSID are different. When trying to connect from different computers it states can not connect.

I suspect a package was updated incorrectly pertaining to routing tables or Firewall zones.
I have a roku device that is only supposed to connect to the guest network but is showing up as connected to regular network 2.4 ghz, guest network 2.4ghz and guest network 5G. I have different subnets for the regular network(192.168.1.1 DHCP lease starts at 100-249) network and Guest(192.168.2.1 DHCP lease starts at 100-249). the Roku has never connected to the regular network

router has been restarted and log is running

Do you mean 2.4G cannot be accessed from the beginning or you could connect, but it was broken?

Except for the Roku device, how about your phone?

2.4G was able to be used about 48 hours ago. It has bandwidth set to 20 mhz for older devices. 5G is set to 80mhz. Tried setting 5G to 20/40/80 mhz and all 2.4G disappeared returned 5G to 80mhz and 2.4G came back but still can’t connect.

The issue I had with the Roku was my doing I think having the wrong static IP address assigned(I put 192.168.1.100 instead of 192.168.2.100)

Right now nothing will connect 2.4G

update:
Got 2.4ghz working not sure how. Noticed that in LuCi wifi overview showed that Generic 802.11AC(5G)WiFi0 and has BSSID 94:83:C4:12:17:25 for both my main network and guest network. Generic 802.11abgn(2.4G)WiFi1 and had a BSSID of 94:83:C4:12:17:26 for main and guest network. I then went to WiFi in LuCi and under device configuration general setup Status showed the channel of 2.4G as 6 but operating frequency Mode was NG Channel was blank and could not be changed. Disabled 2.4G for both networks turned them back (did this 2 times) on and 2.4G started working but was a open network for both(no security) went back to GL-iNet GUI and changed open to wpa2/wpa3-PSK/SAE. This allowed me to connect to 2.4G on both networks. After 5G BSSID is the same but 2.4G BSSID is now root for main and guest network ( I’m not sure if this is correct) Have not restarted and have a log of the past 48hours.

Thanks for the update. Let’s wait and see.

This also just happened to me on my AX-1800 in the last week. I have a printer and doorbell running on my 2.4g network (everything else is on the 5g). Yesterday I noticed that neither of those devices were connected. I then tried to connect to the 2.4g network on my phone and iPad, but they both failed to log in. I have not changed any router/wifi settings in the past week. I can’t think of an explanation as to why my 2.4g network would just stop working.

I have tried the following so far:
Disable/enable 2.4 network
Disable/enable 2.4 guest network
Change channels (it just reverted back to 5 on its own though)
Change security to WPA2 PSK (again, it reverted itself to WPA2/3 SAE/PSK)
Change password
Reboot router

Nothing has worked yet. Did you ever find out what was going on?

Also just tried changing security to “Open” with no PSK and I still could not join the 2.4g network on my iPad.

Can you give the firmware version please?

3.213 the latest one

can you let me know if the 2.4G signal is very weak or strong?

Can you connect to the 5G wifi?

Kind of a dumb question do you happen to know how many restarts have been done over the life cycle of the router, I seem to remember reading that at the 10th or so this occurs and was a known glitch in something.

The 2.4G network still showed a strong connection but I couldn’t join it. My 5G network continued to function normally.

I don’t know for sure, but it was probably in the ball park of 10 restarts at this point. It’s about a month old and I have done some troubleshooting a couple of times.

While I was at work today, the 2.4G network suddenly started working again because I started to get notifications from my doorbell and printer again. No one did anything to the router while I was gone today. It just started working again!

Thats similar to what happened to me it just started working. I still reverted it with no settings saved and updated the firmware to the newest. When it occured I was changing the bandwith for 5G to 160Hz(THIS IS NOT SUPPORTED) trying to boost speed and changed 2.4G to 40hz. I think the 2.4g connects to itself and then times out after a while. Current settings a 20hz on 2,4G and 80hz on 5G no issues and running 3.213
