At home I've got a Linksys WAG54G V2 ADSL Router\AP combo. Had a few issues with it dropping the net and wireless connections when I first got it but the latest firmware update seems to have sorted that and now it's as solid as a rock. Desktop PC has a WMP54GS PCI Wireless card and using the built-in Broadcom 802.11g card in my laptop. Also have a Linksys WGA54g wireless bridge plugged into my Xbox which is running XBMC. Stream all my movies and MP3's from the desktop PC upstairs. Works a treat

The only downside to my setup in the Xbox wireless bridge doesn't support WPA and all the other stuff does. I emailed Linksys about it and they said they're looking at bringing out a firmware update to remedy that...I'll believe it when I see it..

Also just purchased a Ubiquiti SuperRange PC Card for my laptop at work. Expensive but worth every cent in my opinion!!
