Title:
  Wireless Very Slow - Intel Corporation PRO/Wireless 4965

Status in “network-manager” package in Ubuntu:
  Confirmed

Bug description:
  In Ubuntu 10.10 and 11.04, my wireless works perfectly. I installed a
  fresh version of 11.10 and the wireless connects, but the transfer
  rate is extremely slow, about 30Kbps (should be around 2Mbps). I
  reinstalled 3 times and no luck. When I connect to my mobile phone as
  a hotspot, I get fast speeds again so this is related to my wireless
  card/router. I have never posted a bug report before so please tell me
  what further info you require. I have a Dell XPS M1530, which is a
  popular Dell range so this must effect others.

  I believe my wireless card is Intel Corporation PRO/Wireless 4965 AG
  or AGN [Kedron] Network Connection

  I saw these commands requested in other topics so thought they may be
  of help;

  brucey@Brucey:~$ iwconfig
