I’m not great with networking but I got talked into this somewhat expensive router thinking it would be rock solid. Not sure how to access advanced settings but going to 192.168.8.1 opens a pretty basic admin panel. Going to “More Settings” in the drop down only shows some limited 5ghz and 2.4G options. There is something called Luci which I can’t seem to get in. I also got one of the Gl-Inet apps which has similar options.
Anyway, I have it running with great speeds all over the house but this only lasts maybe 48-72 hours before everything gradually slows to a crawl and eventually kicks all devices off and I have to go upstairs and reboot.
Try a firmware upgade latest version is 3.208 you can use the GL-iNet GUI click upgrade and should show show version if a new one is available. Use different names for you 2.4 ghz and 5ghz networks both you primary band and guest band .(there is a issue with roaming handoffs). LuCi is you OpenWRT GUI with a huge amount of customization. It is using a old version of OpenWrt Chaos Calmer 15.05.1 but will be updated to a new version hopefully soon.
The slow speeds could be you ISP throttling you internet, but is problely the router needing a firmware upgrade. It is also advised that you restart your router once a week to clear things out of memory caches and delete old software.
To log into LuCI UI, the Username is root and Password is the same as the Admin password in the GL.iNet UI.
LuCI → Status → System Log and LuCI → Status → Kernel Log are good functions to check for errors/notifications in the logs. They are cleared/volatile on reboot, so you have to review while the router is still running.
Personally, I use TP-Link HS103 smart plugs on some network devices that can be scheduled to power off/on based on hourly, daily, weekly. Using the Kasa app, I can even power off/on remotely to reboot at any time.
