Could cleaning be helpful...
It was sometimes helpful in my previous life with Tomatos...
However if you could indicate an old long used and fully checked and approved working build from history , I would be happy to try it.....
For me the latest Asuswrt-Merlin (246.20) is (obviously) the most stable build. I didn't test Asus's build 260 at all, but since it uses the same wireless driver as Asus's 246 I assume it will display similar stability issues for some users (not everyone is affected).
Indeed, sometimes an nvram wipe can fix some weird issues, but I would start with changing the interference option first.
