Comment 26 for bug 1159145

Hi Luis and others, what model of wireless chip do you have?
If its an Intel Advanced-N 6235, please find my experience below of this problem SOLVED:
I had exactly the same issue as described in this bug, with a 6235 wireless chip in my laptop.
After a while, I became increasingly suspicious that it was a hardware issue, not software/kernel/driver.
I bought a newer replacement 6235 chip, popped in my laptop, and the problem is now solved.
This was on U 13.04, and I'm now on 14.04, and it has been running perfectly ever since.
So there is definitely no problems with the kernel or driver in Ubuntu for this chip. I can't comment for other chips, but if you have a 6235 chip, I would strongly suggest purchasing a new replacement, fitting it, and you will find your issues resolved.
