I have been having connection issues with my Toshiba Laptop. My ISP said he thinks it is probably my WiFi adapter inside the laptop. I removed the cover, but could not find the chip on the motherboard. The system is still under warranty so I didn't remove the motherboard from the keyboard -- my other Toshiba has the WiFi adapter just inside the case. I contacted Toshiba to see if I could get a diagram/schematic showing where things are and they gave me the irisvista.com site, but there is nothing there for the L55. I'm not a complete newby at working on systems, but without taking this completely apart and voiding the warranty, I'm not sure where to look. Can you point me in the right direction? The reason for doing all this is that the laptop will only connect to my router if I'm right next to it. I'm trying to rule out the adapter because CenturyLink swears it isn't them and won't proceed further until I prove otherwise. Thanks!!
