Wired Wifi issue / Popcorn / Chromecast

Wifi issue

Recently have found a weird wifi issue with friends lenovo laptop with Broadcom 802.11n Network Adaptor chip.

Windows 8.1 Wifi showing "limited" or "No Internet Access" on connecting to some accesspoint and some are ok.
it seems the lastest driver for Broadcom 802.11n Network Adaptor have issue with AP only supporting 11n. (which is the default for most of new APs and not supporting legacy devices)
it end to be a new broadcom driver issue from both lenovo, broadcom and microsoft website.

so by using the old driver from stock windows 8 seems to fix the problem.



Here's the instructions:
# Open Device Manager (search Windows Help if you don't know what this is)
# Select 'Network adaptors' and then open (double-click) Broadcom 802.11n Network Adaptor
# Go to the Driver tab and click the Update Driver... button
# Select 'Browse my computer for driver software'
# Select 'Let me pick from a list of device drivers on my computer'
# Select the "Broadcom 802.11n Network Adaptor (Broadcom)" entry from the list, and click Next
Well, it worked for me.
