I have Linksys WRT1900ACv2 and OpenWRT 15.05.1 running for a while and still having stability issues.
What have been done:
Installed watchdog script which fixes wpad / wpad-mini / hostapd stop working bug.
Upgraded WiFi drivers to 3.18.23+10.3.0.17-20160531-1.
opkg list-installed | grep mwlwifi
kmod-mwlwifi - 3.18.23+10.3.0.17-20160531-1
However, same issues with WiFi stability remain, they appear at random interval (connections are stalled or dropped, while OS appear still running fine).
Question is - what to do next? Routers are in working environment, there are no much time for experiments.
Is there any new WiFi fix for OpenWRT I'm not aware about?
If I upgrade to LEDE:
2.a) Which version doesn't have this annoying WiFi issue? Some say for example only rc2.
2.b) Can I upload settings from OpenWRT, or everything have to be recreated manually from scratch? I have a LOT of custom firewall rules.
2.c) Do my custom scripts (watchdog, sub2rbl, fan_ctrl) will be saved or I have to upload them again? Or I don't need watchdog and fan_ctrl anymore, only brute force defender sub2rbl?
2.d) Do I need to do any manipulation with bootloader not loading correct kernel after reboot? I read about it somewhere but lost link.
Thanks in advance for any suggestion(s).
