Bug Description

Binary package hint: network-manager

I have Netgear wndr3700 router, that has pretty nice capabilities. Couple of days ago I upgraded to 10.10 from 10.04 - both 64 bit. Ever since I upgraded, my wireless connectivity is extremely bad. Speeds are horrendous. It does not want to connect with more than 54 mb/s. With 10.04 (Lucid) I always connected b/w 200-300 mb/s. I am sitting about 3 ft away from the router looking directly at it.

N support in the iwlagn driver was disabled in Maverick due to issues with performance not being stable enough, whereas up to 54mb it was. This was recently fixed in the current development release, Natty Narwhal.

I'm marking this bug as a duplicate of bug 630748 since it covers all the information about 802.11n being disabled or enabled in different versions of Ubuntu.
