I had the same problem (same symptoms), but with a different solution. Here's what I had & how I fixed it in case it helps anyone else.
The situtation
1. Before getting a Cisco/Linksys E3000, I had a Linksys WRT54GL, & everything worked fine.
2. Replaced it with a new E3000.
3. All computers could reach the Internet via Ethernet (a.k.a. wired) connections with no problems. This was a Playstation 3, two XP desktops, a Win7 desktop, & an Acer Aspire One laptop.
4. iPhone could reach Internet wirelessly.
5. The Acer Aspire One laptop could not reach the Internet wirelessly. (This was the problem.) Like pajuliet said, the OS reported that there was a good wireless connection, but I couldn't do anything with it: browsers couldn't reach anything, couldn't ping anything.
The solution (brief)
The Acer Aspire 1's wireless network chipset is Atheros AR5007EG. The solution was to upgrade that driver. Ultimately, upgrading to version 7.7.0.523 worked. After that upgrade, I use the Easy Quick Key (or whatever it's called, on a USB memory stick) to setup the wireless connection. After that, it's working great.
The solution (details)
I connected the Acer Aspire One to the network with Ethernet (a wire).
Searched the web for the most recent driver for Atheros AR5007EG for Windows XP, 32-bit. The most recent I found as of 2011-02-26 was version 7.7.0.523. Found it at this .cz website. (The site is an eye-sore, & it tries to sell you some kind of "AtherosDrivers.exeAtherosDrivers.exe" utility which I neither needed nor trusted. However, if you scroll to the bottom of the first big section, there's a "click for download" link. I used that to get just the drivers in a ZIP file.)
With the driver in hand (so to speak), run "devmgmt.msc" to get the Device Manager window.
Expand the "network adapters" & double-click the Atheros AR5007EG device to get its Properties window.
Use the "Update driver" button.
To update the driver, I took the default of having Windows search for the driver, but I used the "Browse" button to root the search at the directory in which I had expanded the drivers ZIP file.
The update worked, no errors.
Shutdown.
Unplug network cable.
Reboot.
Use the Cisco "Easy Setup Key" (or whatever it's called), which I had previously setup on a USB memory stick.
Used a web browser to verify that everything was working fine.
Reboot & verify again, to be sure.
Whew! Lots of steps, but went off without a hitch. The only difficulties I encountered are in the next section (so you can avoid them & save yourself some time).
(Though I had to track down & install the drivers myself, the correct diagnosis of an out-of-date driver goes a tech from Cisco. Thanks again)
