My wifi router is tending to drop out roughly once a day. Symptoms are that my phone and tablet lose the connection: sometimes the PC and laptop which have an ethernet cable to the router will also drop out. The solution is to unplug the router power supply, leave it a minute, replug and the router boots up - although sometimes a reset is also necessary. Then it works again.
I used InSSIder to check whether anything nearby was on the same channel: it isn't. The wifi's on the same channel are -90dB.
However the signal strength from my own WiFi shows dips from the normal -60dB down to -90dB roughly every minute, could be oftener, could be less.
Picture below says it all. Is this usual ? Because I can't believe it is !
Note: the router is several years old and if it has to be replaced can anyone recommend one that's easy to set up and has been problem-free.
