I've been using my netbook to get online for some time. However, recently my dad needed to reboot our modem several times because he was encountering problems with his laptop. This got the wireless working for a little while, but the need came to restart the modem again, so he did. Unfortunately, this put the wireless on the modem out of action. Originally, my laptop wouldn't even recognize the network's existence, but after a 3-hour-long tech support call to AT&T, our internet service provider, I finally got my laptop to recognize the network. Although the tech support lady was very helpful, and walked me through doing numerous things to both the laptop and modem, my laptop still will not connect fully to the network. By "will not connect fully" I mean that it gives me an error message, saying "connection unsuccessful", and on the list of networks, listed next to my network it says "Limited Access". I've attempted to troubleshoot the problem multiple times, and so far the only thing that comes up is the message "Windows cannot connect to [name of my network]", and something saying I don't have a valid IP configuration. I have full access to the modem's configuration as well, and I've checked the firmware and other things to see if there is a problem with the modem. After numerous tests and diagnostics, nothing seems to come up that says there is anything wrong with the modem, but the limited access problem still occurs for my Dad's, my Sister's, and my laptop. Wired connections seem to work fine though. Can anyone please help?
