I installed windows 8.1 pro on my laptop which is an inspiron n4010 r, which came with windows 7, decided to upgrade. the wifi card works, it detects wifi networks and all, it connects to my wifi network but it says limited. i tried googling some info about, tried the suggested drivers and none work. again im running windows 8.1 pro 4 bit. an it detects the networks and connects but stays on limited. also when i go to device manager on other devices, the PCI Simple Communications Controller has a yellow exclamation. cant find a fix for that either, any help would be gladly appreciated.
