1. In Device Manager, right-click on the Intel card and select Properties

2. Then click on the Advanced tab.

3. You will see an option called Wireless mode. Set the mode from 802.11a/b/g 

   to just 802.11b/g. This will prevent the card from scanning or accessing the 

   5Ghz 802.11a band and just leave you with the 2.4Ghz b/g band to work with.
