Last week I discovered that one of the two cores on my Asus router had a constant load of 100% after a firmware update that I did a couple of weeks ago. This is a known problem with Asus routers it seems. In an effort in trying to fix it I gave the whole Aimesh setup (three asus routers) a factory reset and reverted back to the old firmware. This solved the problem and so far it looks like my android devices are working stable now for the first time in years. Prior to 1.7 release nothing ever worked, it all seems to be o.k. now.
