OK, here's the situation. I have a Dell E1505 laptop with Windows Vista that I use as my main computer. I am connected to the internet with a 2wire2701HG-T router/modem. I just bought a Acer Aspire One D250 with Windows 7 Starter and connected it wirelessly to the network. Now, however, when the Dell is connected to the modem by ethernet, my preferred connection for security, speed, and battery issues, the internet connection on the Acer slows down to nothing and soon disconnects. After a bit, it reconnects, but is still very slow, only to disconnect again. However, when I connect the Dell by wireless, everything works normally. Is this a modem problem, or is it an issue with one of the computers? I must admit, my networking skills don't go beyond being able to set up a network name and password.
