I have a new wireless router now and that seems to have fixed the issue. Maybe it was a compatibility issue with the old one? Strangely, a couple of times using the old one it did jump up to normal speed for a while but then went down again.
I'm happy to close this ticket as I can't provide any more info and doesn't seem to have effected anyone else -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/875780 Title: Wireless Very Slow - Intel Corporation PRO/Wireless 4965 Status in “network-manager” package in Ubuntu: New 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 lo no wireless extensions. eth0 no wireless extensions. wlan0 IEEE 802.11abgn ESSID:"dlink39" Mode:Managed Frequency:2.412 GHz Access Point: 1C:AF:F7:29:5C:9E Bit Rate=65 Mb/s Tx-Power=15 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=59/70 Signal level=-51 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:458 Invalid misc:0 Missed beacon:0 brucey@Brucey:~$ iwlist wlan0 scanning wlan0 Scan completed : Cell 01 - Address: 1C:AF:F7:29:5C:9E Channel:1 Frequency:2.412 GHz (Channel 1) Quality=52/70 Signal level=-58 dBm Encryption key:on ESSID:"dlink39" Bit Rates:1 Mb/s;
