Wireless connections to XP-based PC and laptops won't stay up. Get error "can't acquire IP address." Have tried new SSID name, changing channels, etc. End up having to either power off/on the RG, or go into the RG and disable/enable wireless. But eventually it drops again. I have noticed that when it drops for the PC and laptops, the Wii stays connected and can communicate. Makes me wonder if there is a problem in how the RG talks to XP.
If your computer isn't getting an IP address but you can see the wireless network and you can attempt to connect to it, most likely the problem is that the key you are entering does not match what the 2Wire gateway has set in it's settings so it is not assigning your computer an address. If you want to troubleshoot to find out if the key is the problem, go into the wireless settings page in your gateway and uncheck the box for encryption and then click save. Attempt to connect again, if it works then you need to check the settings and enter the information correctly. The best thing you can do is find where your wireless manager on your computer stores it's "preferred network" list and remove your wireless network from that list, if it has a key typed incorrectly thats where it will be storing it. Once it has been removed, the next time you attempt to connect to your network it will prompt you for a key.
