Here's the situation: I have high-speed internet with a Linksys wireless router. Connected directly to the router via a hardline cable is a laptop with Win98. The internet on this laptop works perfectly. (Usually) connected wirelessly is another Dell laptop with WinXP. Internet no longer works on this laptop. I've connected it directly to the router, moved it right next to it, etc. and no internet. It keeps saying "acquiring network address" and fails to do so, regardless of whether it's connected via hardline or wireless. About a week ago, the internet completely stopped working on BOTH laptops, so we had the provider come out. Whatever they did, they fixed the internet....sort of... For a while, BOTH laptops were hummin' along just fine, and now all of a sudden, a few days ago the WinXP laptop simply will NOT connect. Here's what I think the issue might be, but I'd like other input as to potential issues: You have to register your PC's MAC address with the provider before it can connect to their network. I used the router's "Clone MAC" feature in order to get the wireless router working, and both laptops were working perfectly and have been for at least a year with this exact configuration. Is there some way for them to block the other computer from getting onto the internet, since the MAC address of the WinXP machine is not registered? It doesn't make sense to me, because it goes through the router, but what do I know... YES, I called Linksys tech. support and the Indian guy on the other line was being a big jerk and was NO help at all. Any ideas, please?? Thanks!!!
