Hello! I have about 20 devices connected to router LinkSys EA6700 with 1.28.0000 -3.0-132 K26ARM USB AIO-64K ROM.
Signal level is maximum on most of connected devices and speed is also very good.
But… randomly (1-3 times in hour or maybe faster-slower) router stops any wi-fi connections with devices and then happened full disconnect from router ((
After 5-10 seconds devices come back wi-fi connection. It's look like router randomly reboots sometimes….
This troubles have been all days ((((

P.S. Also this disconnects occurs while intensive data exchange between router and device. Level of wi-fi signal greatly slow down and then happens full disconnect from router…
