After noticing that the problem, for me, only seems to be on the 2.4 GHz band, I have found the problem may not only be with the 6235 card. While I was running my router only on the 2.4 GHz band (5.2 GHz disabled on router) my wife noticed that her computer was not connecting well, it has an Intel WiMax 6250, and yet another computer has the Intel WiMax 6150 card. Never noticed these slow downs and drops because these computers normally are at home connected to the 5.2 GHz band. I uninstalled the 15.x driver/software on the 6250 and installed the 14.3.1 driver/software on it, connection is much better. Too bad the 14.x drivers do not support the 6235 card. So, Intel, I think the problem may be more wide spread than first thought, looks to me like your 15.x drivers have a 2.GHz band connection problem, period! I get a stable 300 Mbps connection on 5.2 GHz, but 2.4 GHz connections are a nightmare! Please work on a solution!
