My X230 had the issue with the 6205. I called Lenovo 2 hour after using it for help. They made it very clear they would not help me unless I paid them $90 to make my new laptop work, that I bought new from their site. It is interesting to see how little corporations care about supporting what they sell now-a-days. I did not bother to post on Lenovo's site after realizing how little they cared about the product they sold.
Buying an ASUS RT-N66U has 100% resolved my issue. No Intel fix would work for more than minutes.
