Lets start off by telling you the hardware that I have: 1) WUSB54G - Linksys wireless-G usb adapter 2) WRT54GS - Linksys wireless-G Router with speedbooster 3) WRT54G - Linksys wireless-G Router 4) Dell laptop with Centrino/Intel wireless yadda yadda 5) secondary laptop to be used with usb adapter Here's the problem: a) when used at the location with the non-speedbooster router, both laptops can connect to the network and the internet with no problems. b) when at the location with the speedbooster router, only the Centrino-enabled laptop can connect to both the internet and the network. The usb adapter can only connect to the router, not to the internet or network shares. I've updated the usb's drivers, changed network channels, etc., but always get a "limited or no connectivity" warning. Any ideas on what the problem is? I've also tried an old 802.11b pcmcia card and it returned the same result. Any help?
