I am also having a wifi Issue. I recently installed a dual boot system on a Lenovo Thinkpad X201. The wifi chipset is Intel® Centrino® Advanced-N 6200. The wifi is blazing fast in Windows, but slows to a crawl in Mint 17.1 xfce. I am talking about average around 35-40kb/s download speeds. I originally thought this was a firmware/driver issue, for I've had problems with Intel wifi chipsets in the past. Additionally, I tried a usb wifi adapter with a Realtek chipset, and the speeds were consistent. So I'm now thinking this is a OS/kernel issue.
I had originally installed 17 (Quinta), and had the same results. I had tried so many different things from searches I had done, I finally figured the best thing to do was a fresh install, and i downloaded and Installed 17.1.
I am not a noob, but far from being a Linux genius. I can usually resolve any issues via forum/google searches, but this time I'm stumped. I really don't want to leave Mint/Ubuntu. I've tried all the major Distros, and some of the fringe ones, but always come back to Ubuntu/Mint. I've been using Mint xfce for a couple years now, and it is by far my favorite, mostly because it has been BS free.
This time, from a suggestion I read in a post below, I tried installing kernel 3.18.1 from the instructions that are posted here: http://www.upubuntu.com/2014/12/install ... 81-in.html . This was unsucessful and I will post the output below, but first things first.

I would sincerely appreciate any help with this issue. I absolutely love my new laptop, and my new dual boot system, but these wifi download speeds are a deal breaker. Althogh I always have a dual boot, I boot Linux 99% of the tme, and have for several years now.
It seems many people are having this same issue,or very similar issues with their wifi, many posted, but no {SOLVED]'s. The oly difference between mine and some others is mine has never once disconnected. It's really slow, but has been reliable.
Does anyone know of a sucessful solution to this issue?????
Thanks in advanced for reading all of this and any input !!
