[Bug 1392038] Re: wireless problem iwlwifi Intel 7260 Wifi problems

  Thread Previous • Date Previous • • Thread Next 
robalrr, did this problem not occur in a release prior to Trusty?

** Description changed:

- I thought this bug was resolved but it is still present in my laptop.
- The wireless network always works very slow and sometimes it does not
- work, the card is always connected to the router but the connection is
- slow and unstable.
+ With Utopic and Trusty, when the wireless network is always connected to
+ the router, it is very slow and sometimes it does not work.
  
- I have a lenovo thinkpad E440 with  04:00.0 Network controller: Intel
- Corporation Wireless 7260 (rev 73).
+ Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b2] (rev 73)
+ 	Subsystem: Intel Corporation Wireless-N 7260 [8086:4262]
