HI guys, I was told that it is possible to plug in a switch TO a router. When I connection my connection from Cable modem to Wireless router , then Switch, it worked But its slower. When I plug in by Cable modem to Switch then wireless router, the other 2 pcs with ethernet cable work fine but the wireless router Couldnt get to work. but how come it the other computer that is using wireless connection detected an Excellent signal but no connection activity. details: Linksys cable modem Wireless netgear Mr814v2 router. GIGafast switch Ez800/8ports. hope that helps...thank you

"When I connection my connection from Cable modem to Wireless router , then Switch, it worked But its slower." New cable between router and switch? Are you using a crossover or is the switch auto sensing mdix? "the other 2 pcs with ethernet cable work fine but the wireless router Couldnt get to work" You get two but now three ip addresses from your ISP. The router didn't get a ip address. "detected an Excellent signal but no connection activity. " Connected to wireless doesn't mean connected to the internet since the router didn't get a ip address from the modem via the switch. modem/router/switch is your best protection
