I have two desktops that are both running Windows XP Professional that were given to me for my children. I have been trying to connect a Linksys Adapter to each desktop and both say "you are connected to the access point, but the Internet cannot be found". One adapter is a Linksys Model USB54Gv2 and the other is a Linksys Model WUSB11v4. My wireless router is a Netgear RangeMax N model WNR834B. If I plug directly into the router I can access the internet fine. I have tried to release/renew the IP but am getting an error contacting DHCP. I have verified that the TCP/IP settings are set to automatically obtain IP/DNS address. I currently have 2 laptops (both dell) and 1 desktop (hp) that are using the router and have no problems. I have also googled to see if there is a limit to the number of systems that can be connected and haven't found anything that states this is the issue. Desperately need help as I have two little ones who are really anxious to get online. Thanks in advance!
