Realtek RT8187SE not connecting

**schurtek** · February 26th, 2010

I have a white label netbook with the Realtek RT8187SE Wireless card on PCIe.

It is not detecting wireless networks consistently. When I am even 1 meter from the wireless router, I get no networks in range, but sometimes I pick up networks that are more than 20 meters from me. I can not connect, even if it is unsecure.

WiFi Radar does not detect the card.

If I run a system check on the PCI bus I get the following:
