I connect to the internet via a wireless usb dongle, specifically an Atheros AR9271, which uses ath9k firmwares.
Recently, I've noticed that my internet was much slower. I couldn't watch 720p YouTube videos, pages took more than usual to load and even my router configuration page was slow (a 60k image was taking a few seconds to load).
The problem didn't happen when connecting via an ethernet cable, though.
After a couple of hours fiddling and searching for bugs, I've found out that it's related somehow to the new 3.15.1 kernel. I've downgraded to 3.14.5 and the problem is gone.
I would like to research this matter though, and, ultimately, go back to using the new kernel.
Does anyone knows if this bug is reported somewhere else? What can I do to further troubleshoot it?

My USB AR9271 wireless NIC, which uses the ath9k_htc module, fails to connect to the AP completely, after updating linux to 3.15.1.

This should be work:
sudo nano /etc/modprobe.d/ath9k_htc.conf
options ath9k_htc nohwcrypt=1
Reboot.
Excuse my poor English.

That did the trick for fixing the slow speed as well.
By the way, I've tried doing that before, but for some reason I was passing nohwcrypt to ath9k instead of ath9k_htc, which seems to be the new (?) firmware. So if you're still unlucky check with both
