Anyone ever experience something like this, or have any idea what the problem might be?

Have there been any nuclear detonations near your home recently?

This approach invariably works for me.

Which Linksys is it?

3RD POSSIBILITY.
Interference. Neighbor bought a wireless router or phone and is interrupting your signal.

Use Netstumbler on your laptops. It will show if a neighbor is interfering.
It wont show a 2.4 phone though.

Stuff breaks down.... DLINK is better than LINKSYS.

Bought mine from the IP. Under warranty as long as I have service with them.

Far more likely, you're experiencing a network config issue with your laptops.

I would suggest that you erase your current network settings on one laptop, and reconfigure the laptop's network settings. You can probably start by directly connecting the laptop via ethernet to make sure the router is routing traffic via the ethernet.

After that, attempt to set up the wireless again.

Set static IPs for the client. Nothing.

Did you manually enter the DNS servers addresses on the laptops? Try a static IP like http://209.157.64.200/
