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?
