Summary: I have been using two of these for 1.5 months now, one on a XP Pro and the other on a Win 7 64-bit installation without a single problem. These were very easy to install and configure(pretty much automatic). I connect to a LinkSys 610 wireless router that is two rooms away (about 22') with 5 GHz signal strength "good" I don't seem to have any access speed issues. The 2.4 GHz comes in as "very good".
Summary: 5 stars to Cisco-Lynksys WUSB600N!!!!! Been having a huge problem with Dlink DWA 160 HW Ver B1 FW ver 2.00 adapter dropping wireless connection all the time (every 5 or 10 minutes), large downloads fail, web pages stop loading, etc. Using DLINK 655 wireless router. "Received Deauthentication Token", "wireless system with MAC address ... associated, wireless system with MAC address ... linked" entries endlessly in wireless router log.
Summary: I installed this (V2) on two machines, both WIN 7 32-bit. One a 6yr old P4 and the other a 2yr old Quad-core. The P4 is Dual Boot XP/Win7, but I did not install in XP. WIN7 could not find a driver, so I installed with the LINKSYS disk. It took about 5 minutes and installed perfectly with excellent signal strength. No secret there, my router, a WRT54G is only about 12ft away. I left this adapter on the Quad and transferred my WUSB54GC to the P4, WIN7 picked up the 54.
Summary: works perfect, used for over a month. I think whoever has complained is not using this with a linksys ultra rangeplus router, or they are using some other crappy router. these are good adapters. also update latest drivers from linksys.com.
Summary: With all the wireless products in the house, the phone the temperature gauge, we had trouble with are "G" wireless and upgraded to the "N" this thing has a 450 foot range. You won't be sorry if you purchase this item.
Summary: Got two of these adapters about two months ago when I upgraded my router to a Linksys WRT610N Simultaneous Dual-N Band Wireless Router , These Adapters have NEVER dropped the connection with the router, We have two computers in my home (Both with this Adapter), I got one in the same room as my router, and the other downstairs (behind a cement floor and one brick wall), ZERO problems so far, I get a very good signal downstairs, the computers feel like they are on a wired...
