I'm having some weird flakiness issues with the Wireless interfaces that I can't seem to track down.
Laptops and phones/tablets (all Apple devices) seem to have full WiFi connection to the 5GHz channel and the speeds to match, but will also drop connection seemingly randomly across a day. This can happen anywhere from a couple to several times across a working day, which gets frustrating.
All the other main devices in the house that don't move (TV, desktop, console) are wired in and suffer no such connection drops - the speeds are consistent with what I would expect through the wire.
When the connection drops, the connection defaults back to the 5G that is available in the area and I'm able to force the device back onto the WiFi faster than it usually would by trying to access LuCI through the browser.
I have seen devices try to connect to what I think is the upstairs router first, because I see a single bar of WiFi before it fills all the way up again -- terrible explanation but I think that makes sense.
My setup consists of two R7800s, running identical firmwares;
OpenWrt 21.02.3 r16554-1d4dea6d4f.
- Main router sits on the ground floor, on 192.168.1.1, with Adguard Home (and a few DNS blocklists) running on top of it. 5GHz on 149 and 2.4GHz on 1
- The second sits on the first floor, on 192.168.1.2 as the Dumb AP (following the wiki guide). 5GHz on 36 and 2.4GHz on 1.
It's worth noting at this point that there isn't much point in the 2.4 channel, since the 5 coverage is (usually) exceptionally good.
I did previously have a WRT3200ACM, but that seemed to be even more unstable, so I replaced that with the two R7800's.
I wanted to have 802.11r enabled on both channels, but did a bit of reading and basically came to the conclusion that it could be causing the problems I was seeing with iOS devices, so have disabled that again but to no avail.
I'm at a bit of a loss as I want to be sure to take advantage of the speeds that the line provides, but with the flakiness I can't have confidence in the connection the Wireless is throwing out.
I'm definitely not the most network-savvy, but more than happy to try and get down and dirty to diagnose this issue.
It's probably worth noting here that I live in an apartment complex, with multiple other WiFi networks in the immediate area. Which was one of the main reasons I went with the R7800s and OpenWRT in the first place.
Thanks in advance!
