is connected to a laptop, I might take a road trip to your nearest WiFi hotspot for a test. A positive connection should eliminate the adapter as the source of the problem. From there you can update the routers firmware and try repositioning any 2.4ghz devices which might be interfering.
I have the Netgear WG111 v.2 USB 2.0 Wireless Adapter on a computer running Windows 2000. I have the Linksys WRT54GS Wireless-G Broadband Router attached to a second computer running Windows XP SP-2. The Router works fine with the second computer (Hard wired) and I have internet access. However, after following the Netgear installation instructions on Computer 1, I have intermittent connection to computer two. In other words, although it is only ten feet away, it has signal strength of 54% to 74% and only connects for a second or two at a time. I need help in diagnosing why the signal is not stronger and why it keeps drops on computer 1. HELP. Thanks.
