I've been having a problem for the past week or so regarding my internet connection. I have a 10MB/s virginmedia broadband that's really fast when I'm the only one to use it (with an Linux machine). However, even if I always have the 5-bar reception, it takes an awful long time just to open a simple webpage as soon as my girlfriend gets back home (and turns her windows 7 computer on, obviously). And she has fast and reliable internet whenever she uses her computer. When I boot my machine on Windows, it also is quite fast so the problem probably comes from Ubuntu... Would anyone have a suggestion? (except for "well just use Windows!" as I need to work on my ubuntu machine!)

Thanks a lot!

Do they both use Wi-Fi? What wireless adapters do they use? – Rowland Shaw Feb 7 at 20:16
So it's really fast when only Ubuntu is on, but when ubuntu shares the bandwidth, the W7 machine gobbles it up? When the ubuntu box boot windows, it's just as fast as before. Sounds like Ubuntu-driver related. – Raystafarian Feb 7 at 20:20
Check that DNS settings are consistent. – BrianEss Feb 7 at 20:39
Can you list what network card(s) are installed, as well as wireless or wired connection? Assuming wireless (5-bar reception). You can probably find the network card(s) by doing lspci in the terminal. – Rob Feb 7 at 21:00
@Rob: Yes, both computers are using Wi-Fi. I got this for the Network Controller (doing lspci in the terminal): 02:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01). – bricebanel Feb 7 at 21:13
