When you post the output of lspci, always include the -nn or -nnv switches. That
way, we get the PCI ID. As there are several varieties of the RTL8192SE, I need
that info. In addition, what are the details of your AP - STA configuration.
What is the distance? Is it 802.11n or 802.11g? What is the signal strength as
indicated by iwconfig or a scan?
