I bought a DELL XPS 12 with Intel® Dual Band Wireless-AC 7260, but the wireless adapter can't connect to wireless router and shows "Limited Network". I tried to download and install the latest driver for windows 8.1 form Download Center, but still the same error. I want to disable 802.11n but can't find anywhere to disable the 802.11n Mode.
If your network connection icon indicates "Limited connectivity", this means you are most likely connected to the router, so the questions are: Do you receive a valid IP address? Do you receive internet connection?
