>Description:
Whenever I try to log in to Paypal or edit Wikipedia, I get no response from the web server after POSTing the form data. Additionally, when I try to email a colleague a file (Claws 3.7.3), the transfer to gmail's SMTP server stops at *exactly* 36864 bytes, every time. The file is only ~600KB.

I am using wireless on a Thinkpad X200:
44C8733I SBB THINKPAD B/G/N 44C5194I SBB INTEGRWIRELESSWIDEAREANETW
which appears to be a RTL8192SE. I am using the drivers provided by the manufacturer combined with ndis.

My MTU is set to 1500, and net.inet.tcp.tso is disabled.

This problem did not happen in 7.2-RELEASE and it does not happen with a wired connection.
