Yeah, it's exactly the same laptop using the same wireless connection.

I have a dual boot on my laptop with win 7 and ubuntu.

At work:
Windows internet = great
Ubuntu internet = great

At home:
Windows internet = great
Ubuntu internet = awful

I think disabling IPv6 is a good idea

Do this again after you have used the home wireless for a while (as long as you can bear it):

ok, ipv6 is disabled, internet is still kinda awful.

here's that info again:

Code:
wlan0     Link encap:Ethernet  HWaddr 74:e5:0b:30:0e:5c  
          inet addr:10.0.2.12  Bcast:10.0.2.255  Mask:255.255.255.0
          inet6 addr: fe80::76e5:bff:fe30:e5c/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:4855 errors:0 dropped:0 overruns:0 frame:0
          TX packets:6365 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:4903402 (4.9 MB)  TX bytes:1263179 (1.2 MB)
and...
Code:
wlan0     IEEE 802.11bgn  ESSID:"Thomady"  
          Mode:Managed  Frequency:2.462 GHz  Access Point: 00:1C:B3:75:E5:BC   
          Bit Rate=65 Mb/s   Tx-Power=14 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:on
          Link Quality=67/70  Signal level=-43 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:2539  Invalid misc:128   Missed beacon:0
gonna try some of the stuff on the previous page now...

Did you try a different DNS?
Is the speed also slow if you use a wired connection?
Do you use wpa?
Try to set an open connection, no encryption, to see if it makes any difference.

Kind regards

That excessive retries value seems to increase. And it's a huge proportion of TX packets.

Do you have any interference, like power cables or fluorescent lines or motors very close to your wifi antenna (which is probably somewhere around the screen of the laptop, if it's built in)?

I don't really think it is interference, since the Windows connection works. It's probably a setting.

What is the iwconfig wlan0 output when you are at work?
