I bought this adapter for my daughter's desktop PC in the hopes of obtaining a decent range. I had an old wireless "B" PCI adapter from Netgear for years, and signal was always very marginal on this PC.
I also bought a Linksys WRT600N router to upgrade my whole wireless system too. The idea of dual band 2.4/5Ghz seemed attractive enough. Also, I thought that by buying from the same manufacturer I should have very few issues.
I have four PCs at home 3 x wireless "G" (XP SP3 + Vista SP1 + MAC)+ 1 x wireless "B" (XP SP3), so this USB Wireless "N" computer would have been the only one capable of all the extra features and range.
The installation of the USB adapter software went fine and it connected almost right away. So I thought I was done. Almost immediately my daughter started complaining of lost connection issues. I blamed it on her finagling with the wireless software, but it turned out that she was right. The system would take a long time to connect after booting up the PC, then would disconnect after 2 or 3 minutes, and would connect again may be 30 min later. I could not manually force a connection (even though Linksys software advisor would say that I was connected to the router).
To summarize, I called tech support today and was pleasantly surprised to speak to a human after no more than 2 minutes. But after 50 min on the phone, and several holds while he was in turn asking questions to somebody else, he came back saying that I'd be better off returning the USB adapter and getting a Linksys WMP300N which he swore is a dual radio band (even though I read somewhere that it works at 2.4 GHz only).
Too bad I bought this online, but it was from Amazon, so I am returning it today.
