Thread: Very slow browsing in Ubuntu 11.04 (Windows 7 partition is just fine)

i thought i'd post here instead of general board.

problem i've been having:

http://ubuntuforums.org/showthread.php?t=1903231

a few days ago browsing speed in ubuntu slowed down crawl. every page takes forever load, when open chromium or firefox lot of tabs load. did bunch of speed tests , came normal.

windows still has same browsing speed always.

happening?

did test: connected directly modem rule out router being problem, it's still slow.

and:

i tried fix:
http://forum.ubuntuusers.de/topic/la.../#post-3005217

, nothing's different.

have ipv6 disabled, , i'm using google's dns servers.

the fix changing network card driver.

here's few commands better picture of system:

it's desktop wired connection linksys router, tried connecting directly modem too, , still same problem. , said, in windows 7 partition , live cd runs smoothly.

by way of test,

uncomment first 2 lines of resolv.conf from
this

cat /etc/resolv.conf
# generated networkmanager
domain cpe.cableonda.net
search cpe.cableonda.net
nameserver 8.8.8.8
nameserver 8.8.4.4

to

cat /etc/resolv.conf
# generated networkmanager
#domain cpe.cableonda.net
#search cpe.cableonda.net
nameserver 8.8.8.8
nameserver 8.8.4.4

save , close file.
test see if speeds things bit


changing file have immediate effect, however, when restart computer networkmanager rewrite /etc/resolv.conf in original quote.
