Comment 1 for bug 176602

I'm seeing the same thing as well with WEP 64 bit authentication. This is on a Dell 1420 laptop.
ipw3945 works but the connection is prone to freezing as documented on Dell's website. Below is the lspci and dmesg output. Please let me know if you need any more information to debug this problem.
