You will not find any Windows 7 drivers for CISCO/Linksys devices - their not sure if or when they willl get around to it.
Simply put CISCO /Linksys SUCKS! I have WPC 300N -no Firmware update, No updated drivers since 2007- even though I bought this two weeks ago. How can a company put a product on the market and not support it - These guys are the Chrysler/GM of the network business - Flaky Drivers, Flaky Firmware, Flaky support! They took over a perfectly good company and then messed it up. Geez Louis - Windows 7 has been on the market over a week and Windows 7 RC has been out since May and they still don't have their act together. I've had no problems with Lenovo, DLink, Buffalo, Netgear or Trendnet but these guys are giving us a heart attack! We have over 36,000 users in my company and no problems with Lenovo, DLink, Buffalo, Netgear or Trendnet but when it comes to Linksys the systems are always have a problem. My buddy who runs an major network of an entertainment company wouldn't touch a Linksys with a 1000 foot pole after all the problems he had with them since CISCO tool over.
Go to Linksyscisco website and do a search for Windows 7 drivers - you'll get 1680 returned references - none of which has anything to do with the search. It's time to give these guys the BOOOOOOT- until they put the "customer" back in "service" and start issuing some real support. CISCO -Get your act together -give us our firmware and drivers or get out of the business - I'm tired of trying to make lemonade from CISCO lemons!
One other thing be careful - Windows 7 updates wants to run an update for "Broadcom Driver" for Linksys devices. Once its loaded you cannot connect to the internet and even if you uninstall and reinstall the old driver you will connect but get dropped every 2 minutes. Broadcom has not perfected the driver for many Linksys (broadcom based) devices.
