So I purchased a Linksys E4200 a couple weeks ago from Best Buy (got the $149 price) and finally got around to setting it up last Thursday. Before I get to my problem, I am happy to say that I have not experienced the "blinking light" syndrome that seems to plauge a number of other owners. In fact, the E4200 is everything I hoped it would be ... except for one problem. I cannot get my sister's Acer Aspire One netbook to connect to it.
It's really strange actually; the netbook picks up the 2.4GHz SSID fine (it's set to mixed mode) and upon selecting it and I input the WPA2-Personal password no problem. Then, it takes forever to finally aquire a network address, like at least 3 full minutes (usually this process takes a few seconds). After that, it tells me it is connected to the network with excellent signal strength. Except, despite it saying it's connected, the Internet does not work at all. If I got into the details of the wireless adapter, it tells me that the router/network failed to give the adapter a network address.
Anyone have any ideas or solutions to this problem? It's very annoying that this is the only device that won't work. For the record, I also have the following all connected to it and running perfectly:
Apple MacBook Pro - running on the 802.11n 5.0GHz band
Apple iPhone 4 - running on the 802.11n 2.4GHz band
Apple TV - running on the 802.11n 5.0GHz band
Sony PlayStation 3 - running on the 802.11g 2.4GHz band
One wired Windows XP desktop
Any help would be greatly appreciated!!!

Whats the OS installed on your computer which is not able to go online? Login to the router setup page and below change the Wireless Channel to 1 or 11 and then check if you are able to go online or not.

Thanks for the suggestion. The Acer Aspire One has plain old Windows XP Home Edition on it; nothing special like a Linux install or anything. I tried changing the wireless channel to both 1 and 11, but neither solved the problem. I also tried setting the wireless bandwith from "Auto" to "20MHz Only," but again it did not work. After that I changed the 2.4GHz mode from "Mixed" to just "G-Only" (the netbook only supports 802.11g anyways) but this also didn't work.
However, I was able to solve this problem earlier tonight, though I am not 100% happy with the solution. The problem seems to be the security settings. For whatever reason, the Acer Aspire One simply connect to the Linksys E4200 using ANY security. I tried WPA-Personal, WPA2-Personal, the WPA/WPA2 mixed mode, and WEP. All failed to actually connect to the Internet. As soon as I turned off all security for the 2.4GHz band, it connects perfeclty (and very fast, just like it should).
Now, I know for a fact that the Aspire One netbook can support secure Wi-Fi connections, because it was connected to my old D-Link DGL-4300 router using WPA2-Personal just fine. I'm not actually blaming Linksys/Cisco for this though, as it could still easily be the fault of the Aspire One (it is a two-year-old netbook after all, and we all know netbooks use the absolute cheapest components available), but people who own crappy netbooks should be aware of this issure. This specific Aspire One uses the Aheros AR5007EG Wi-Fi chipset, for future reference. And before you ask, yes I have the newest drivers installed for it.
Not having any security is obviously not desirable, but for me it's not the end of the world. I know both of my neighbors and neither of them even own a PC (they are both very, very old people lol). That leaves people across the alley way, but my router is located at the very front of my house. The signal would have to stretch across my entire house, the entire backyard behind my house, across the alleyway, across the entire backyard of the person's house behind mine, and then finally it would reach their residence. I've read the range on the E4200 is pretty good so maybe it can reach the far; I guess I have a reason to go walking around my block seeing how far my iPhone can keep a signal

I tried using the newest drivers available on Acer's website and another set of drivers I found in a Google search. Both had the same problem. I'll keep playing around with it, but in the meantime I have a couple questions for any other Linksys E4200 owners:
Anyone else happen to have a notebook with an Atheros Wi-Fi chipset? It doesn't necessarily have to be the same AR5007EG chipset that is in the Aspire One netbook I am having problems with, but any Atheros-based chipset. And if so, how is your experience so far? Does it work correctly?
Also, anyone happen to use the MAC Address Filter on the E4200? I tried it out once on my old D-Link DGL-4200 router, but it seemed to massively affect performance. I could use it again on my E4200 as a way around not having any wireless security turned on, but not if it also drops performance by a lot. That was after all one of the biggest reasons I bought a new router

Try to upgrade/re-flash the firmware on your router.
Connect the computer to the router with the Ethernet cable. Download the latest firmware from Linksys website and save it on your computer. Open the setup page of the router and upgrade the firmware on your router.
After upgrading the firmware on your router, reset the router for 30 seconds. Power cycle the router and reconfigure it manually.
Use WEP security mode and see if you can connect to the wireless network on your notebook.

Alright, so I got everything working now! I had tried using two different drivers for the Atheros AR5007EG chipset before; one was version 7.2.xxx and that seemed to be the most popular around the Internet; the other was version 7.6.xxx and that is the verson that Acer has up on their website for the Aspire One netbook. Neither of those worked using security on the Linksys E4200.
Earlier today I found another driver, v7.7.xxx, that is inexplicably only available on Atheros' Czech website (not the U.S. one). I installed it, not having much hope at all, reconfigured my router settings for what seemed like the 100th time, and to my surprise it worked. The Aspire One now has no problem using WPA2-Personal on the 2.4GHz band.
Thanks to everyone that replied with suggestions. And to those of you with Aspire One netbooks, or any other computer using the Atheros AR5007EG chipset, just know that ONLY the v7.7.xxx drivers will work properly with the Linksys E4200 router.

I had the same problem with an ACER Netbook ONE and the Linksys E3200. Do a Google search for Atheros 7.7 drivers, the Atheros.cz website should come up and search for your wireless model, download and install. Thank you to ALL who contributed to this post, you saved me alot of time and ANGER, LOL.
