Problems with Toshiba L505D Realtek Wireless Adapter

I have the Toshiba Satellite L505D S5965 (http://laptops.toshiba.com/laptops/satellite/L500/L505D-S5965), and the WiFi Adapter stopped working a few months after I bought it. I tried to fix it by uninstalling the drivers and reinstalling them, but that didn't work. I ended up giving up and buying a USB WiFi (NETGEAR WG111v3 54 Mbps Wireless USB 2.0 Adapter), but it doesn't work very good and I have been having more and more problems with it. Is there any way I can fix the original WiFi Adapter? It was the Realtek RTL8187SE Wireless 802.11b/g 54 Mbps PCIE Network Adapter. There is another Realtek adapter under network adapters in the Device Manager which is called Realtek RTL8102/8103 Family PCI-E FE NIC. Could it be conflicting with the other Realtek adapter? Does anyone know how to fix this?
