Problem: After a few hours, one of two wireless devices are unable to reconnect to wifi network, to temporarily fix, either a power cycle of the device or the router is needed, then the device is able to reconnect to the network. The devices that are having problems are wireless audio streamers, Logitech Squeezebox Radios, I have two. Usually, one of them loses wifi connection, not both, and it seems random which one loses the wireless connection. Router: ASUS RT-AC66U, merlin 18.104.22.168.270.24 Background: Have other wireless devices in the house that NEVER lose connections, tivo, wireless scale, Squeezebox Touch (a different model then the squeezebox radios listed above, only have 1 of this one) all retain wireless connection over time and do not need to be power cycled to work I try and leave all devices using regular DHCP if possible, the less I have to tweak the network the better. I have setup 2 static DHCP reservations for a Synology NAS and an imac. Settings that seem to fix the problem: 1) Giving them each a unique host name in their /etc/hostname file, the squeezebox radios are tiny linux boxes: *)enable ssh on each radio, then went into both radios and set the name in the /etc/hostname file *) RedSqueezeboxRadio *) BlackSqueezeboxRadio This seems to have fixed the problem, it has only been a day, so we will see. 2) Turn off automatic channel selection, picked a channel at random, in this case channel 9. This also seemed to fix the problem. But only left this setting enabled for a day, so do not know for sure that this setting fixed the problem. What did NOT work: I set up a static DHCP reservation in the router for 1 of the radios. Within a few hours, both were unable to reconnect to the network.
