This Toshiba Encore is driving me crazy. Since buying it a few weeks ago, I've been unable to connect to our Sky wifi router (cannot connect to this network or if it does finally connect, I get the limited access message). It connects fine to a friends Sky Hub and even works with a usb Ethernet adaptor, but I'm not going to change my router for this tablet because it should work with everything. I have the latest Broadcom wireless SDIO driver (220.127.116.11) and have even tried the Microsoft driver but without success. How do I fix this problem?
