I was previously using a Motorola 4100 modem and Linksys Wireless-G Broadband router, linking a Dell XP desktop to an HP XP desktop with a Lynksys Wireless - G USB adapter, and a Toshiba laptop that has an Atheros AR5007EG wireless adapter. The laptop always connected to the internet, the HP connected but often lost the connection. I replaced the modem with a Motorola SB5101. No problem with the laptop. The HP would not connect. So, I replaced the router with a Netgear Wireless N300 router. Now....the HB is connected, but the laptop connects to "local only" and "limited connection" not the internet. I have tried everything I can think of, nothing. Please help.
