Hi. Thanks for the images!
I've been using this image since Dec. 2020 on two WR841 v11. I'm not sure which version I started with but probably the 19.07.4, and I only updated once to OpenWrt 19.07.5 r11257-5090152ae3 in January 2021.
I'm asking for help on debugging the wireless performance on these.
The problem: after a while of being turned on, the wireless is completely broken but it's still broadcasting the SSD. If I try to connect to it, I can't even get an IP address from the dhcp and the connection is closed (android). The wired internet is still working. A reboot appears to be required to restore the wireless.
The version I tried in December, had this behavior very frequently - on the first 30 min to 2 hours of being powered on. This last version was holding fine for some weeks and then failed. I rebooted them yesterday and today they are again with no wireless connectivity.
Some highlights on config I have:
- one gets internet from ISP through DHCP, provides the internal networks, dhcp server, firewall, etc, the other one is a dumb AP;
- the dumb AP has most of unnecessary servicies disabled;
- two networks on two vlans (lan and guest);
- two SSIDs for the two vlans;
- both are broadcasting the same SSIDs, same wifi configs at different channels;
- most known devices (mobiles, laptops, etc.) have a fixed IP on the router.
This problem happens at least on the dumb AP - I just rebooted that one and I got the wireless back.
I just have no idea where to start looking. I'm comfortable with linux (I only use linux) but my network skills are very limited.
I think I was affected by this [TL-WR841N v8 ath79 Link Unstable - #9 by leeandy] because on dmesg I saw something like this:
[ 8829.952701] eth1: link up (10Mbps/Half duplex)
However this also affected the wired network and now only wifi is affected.
I just noticed the main router might rebooted itself 3d ago.
Current dmesg look great on both and RAM usage is at 85% for the main router (no wifi clients) and 90% for the dumb AP (3 wifi clients).
I'm holding the update to 19.07.7 for some days in case you want me to check something on this version.
Any thoughts?
Thank you!
