wired routers

I purchased the WRT54GS to upgrade an outdated router that I'd had for about 4 years.
Ultimately I was hoping this router would allow me to use my laptop anywhere in my town home (~1300 sqft) AND work with Xbox Live despite it's absence from the list of approved routers; I figured "how much different could it be from the WRT54G", which IS approved for Xbox Live.
With some minor difficulties I was able to get it to work with Xbox Live. You'll need to toy around with the security settings (SPI, Anonymous Internet Requests, and DMZ) a little bit, but it WILL work. Once Xbox Live is connected you can re-secure everything until you turn off the Xbox... at which point you'll need to go through the routine again when you want to reconnect. This has something to do with the way Xbox initiates communications... hopefully Linksys releases a firmware patch to correct this simple, but annoying issue.
The laptop network connection works anywhere in my town home, but if I take it outside onto my deck the signal is eventually dropped. To be fair the router is on the complete opposite side of the town home when I'm on the deck. I'm betting that I could improve my coverage area if I could move the router to a central room and elevate it a little bit. The WLAN coverage is about what I'd expected.
The browser interface is a breeze so adjusting your settings to work with Xbox and secure your WLAN is not hard at all. Initial setup was incredibly easy. I literally plugged the router into my cable modem, plugged my desktop PC into the router and I had internet. The router automatically spoofed the MAC address required to get through the cable modem.
I haven't had to use Linksys technical support, but their knowledge base is decent enough to solve the most common problems. This product is fairly new however, so knowledge base articles for out of the ordinary problems are somewhat sparse as of right now.

Yea... it was a pain to setup. Especially because I'm using AOL DSL. I tried the setup disk and everything seemed to be going great but in the end, the computer didn't recognize my modem. I looked online at Linksys.com and under support I typed in AOL and then it showed a list of Q&A. I read a couple of them and tried it. I figured out that the instructions were a little off and eventually got it all working in just under 3 hours. If I were to do it again, I think I could set it all up in like 20 minutes.

As far as performance, My Sony Viao PCG-Z1VA has a built-in 802.11b but I wanted the best performance possible so I got the Linksys WPC54GS Wireless-G Notebook Adapter with SpeedBooster to match. Connection to the web from my laptop is unbelievable. Its as if I was on the desktop, wired directly in the modem. I ran some speed tests and it shows that I'm on par with the desktop.

My signal strength is around 80% throughout the entire house. The transfer rate is consistently around 125.0 Mbps.

Its as if the notebook is just another drive in my desktop. I couldn't ask for better performance.

no problems so far with 1 airport extreme card and one linksys PCI 802.11g on a win xp box. using stock firmware.

worked well immediately, is fast, and stable.

avoid the d-link pci card, had problems with this router.
