I am usine a belkin-n router, I have 7 computers running off the one router. 2 are hardlined in the other 5 are wireless. Have been running this system for approximatly a year. Within the last 3 weeks at roughly the same time in the evening I have been experiencing a lag issue. It has kicked different comp. out of AIM chat rooms, off online games and even from msn messenger. during a couple of these episodes have run a speed check and it has checked out. went through each computer and ran virus scans, even restored a couple to original set-up. have gone so far as to shut down all but one computer and still seeing the lag issue. not all 7 computers are on typicallly at the same time usually only 3-4. Any help or ideas anyone has would be appreciated.
