Comment 53 for bug 401126

I thought the driver was working fine on the TOSHIBA Satellite A500D-10K (RTL8191SE) because I could connect to wireless, but I didn't try to browse the Internet until today. Well, it works but after a while, the link stays up but there is no connection really, and dmesg gaves a lot of these errors:
