I have the same router. And the USB adapter I have is the WLI-UC-G300N. When you install the drivers from the install disk, it places a "BUFFALO" program group on your Windows Start menu that includes an item called "AirStation 300Mbps Mode Setting". If you click on it, it will try and connect to your router at 300Mbps. My problem however is that when I do this, I get a dialog box indicating "AirStation is not found". My resultant transfer speeds are ~ 5Mbps. Has anyone else had this issue with the combo of WHR-G300N router and WLI-UC-G300N adapter? I've also tried installing the adapter client software that comes with the install disk. If I try to connect via the Buffalo client software instead of the Windows Wireless configuration, it seems like it tries to connect at 300 Mbps, but continuously drops the connection. If I look in the router logs, I see something like the following repeating over and over:
2009/04/29 18:39:59 WIRELESS ra0: had deauthenticated : 00:1d:73:bc:7c:ab
2009/04/29 18:39:59 WIRELESS ra0: had disassociated : 00:1d:73:bc:7c:ab
2009/04/29 18:39:57 WIRELESS ra0: had associated successfully : 00:1d:73:bc:7c:ab
This repeats over and over, as the adapter connects and then almost immediately disconnects.
I should note that I have my router set to the 40 MHz mode, channel 1 (extension channel 5). I also have a WLI-TX4-AG300N ethernet converter on the same wireless network. I experience transfer speeds across the router/Ethernet converter link of ~ 30 Mbps. Far short of what I'd expect, but not bad. At least the connection is solid with the ethernet converter.
Are there maybe compatibility issues with wireless N usb adapters and the Buffalo WHR-G300N? I see similar behavior when trying to use a DLink adapter on the WHR-G300N router. But all my wireless G clients are fine.
Thx for any thoughts or suggestions.
