I have a Asus DSL-N12E router (DSL uplink + router + Wi-Fi AP) at house, and on average 5-10 devices which connects to it with Wi-Fi. Frequently different devices reports they lost Wi-Fi connection. Sometimes they reconnect seamlessly, sometimes one have to click “connect.” Always there’s no problem with reconnecting except sometimes you have to do it manually.
Yesterday I had 3 laptops on my desk (one with Linux/Debian, one with Windows 7 and one with Windows 8.1) and I noticed they all disconnect at the same moment. The router has some system log, but nothing there and I didn’t find an option to enable some extra logging; maybe I missed something?
I can’t think of any interference from the environment since I have no microwave and I live in the country with only 2 houses in the neighbourhood. I can’t see any Wi-Fi devices announcing, except 4 other wireless devices—link to the family house, and AP there—which are on different channels. Asus in on channel 11, the others on channel 8 and 3.
Any idea how to diagnose it, or what to change to fix the problem?
