2 of the 3 PCs sit side by side w/in two feet of the 2wire gateway. One stays connected; the other doesn't. The third sits ~10' away and stays connected.
I have ATT's 2wire DSL gateway, and it works fine w/all but one PC. The problem PC is my HP Touchsmart. It constantly (several times each hour) gives me one of several error messages that say it's not connected to the Internet or to the gateway. That never happens w/any other computer on the network. All have wireless connections.
Is this a problem w/the PC (more likely) or the gateway (less likely, since the other two work fine)? How do I fix it?
