Wireless Adapter cannot connect with AES (but works with TKIP)!
Hey,
I'm using a 3Com 3CRUSBN175 USB wireless-N adapter to connect to a 3Com 3CRWDR300A router with WPA2 enabled. The PC with the USB adapter and a laptop with an Intel 4965AGN can both see and connect to the network when TKIP encryption is used.
However, when I turn on AES, the USB adapter is not even able to see the network! It is fully certified for 128-bit AES according to the website. I am using the latest drivers/firmware for all kit involved.
Any ideas please?!
Cheers,
Suman

Re: Wireless Adapter cannot connect with AES (but works with TKIP)!
Which OS version and service pack?
IIRC, XP prior to SP2 didn't do everything with WPA properly, so perhaps it's that?
It's also possible said USB adapter has a vendetta against you...

It's XP Home SP3 with all the latest updates from Windows update... I should mention the problem exists when I use WZC as well as the 3Com connection utility.
I like your vendetta theory!
Cheers,

SOLVED!
Realised that the adapter was plugged into a USB1.1 port (old Asus A7V333), so plugged it into a USB 2.0 - now works perfectly, at up to 270Mbps. Very random, but wooooo!! 
Cheers :p
