I'm on a Netgear N300 router. A few weeks ago I did a firmware update on it and ever since then the router and modem have had some syncing issues. The desktops and wireless devices pick up on the wireless signal but no internet/servers found. I've contacted the cable company and all they say to do is reset the router (unplug router for 10 sec, unplug modem wait 10 sec, plug router in after 10 sec, then plug modem back in.) Now this actually does work for a while, but eventually it looses sync again and we must reset the router again. It happens 1 to 3 times a day. Any idea what the problem here is. The setup was fine for 5yrs then after I did the firmware update this problem started. Any help anyone may be able to give would be much appreciated.
