Title:
[Dell Precision T3400] Intermittent ethernet internet connection
Ubuntu 12.04 (networking using the tg3 driver)
Status in “linux” package in Ubuntu:
Expired
Bug description:
I have spent hours trying out dozens of solutions from the
ubuntuforums and askubuntu, nothing seems to help. Ethernet cable and
plug (in office wall with many ethernet plugs available) switched to
test if this is the problem.
My internet connection sporadically and regularly drops. Sometimes it
is that webpages take a long time to load, or never do. Sometimes this
can be fixed by reloading the page, sometimes this does nothing. In
those cases the only solution is to either disable and enable
networking or click on the supposedly connected wired connection I am
using to get it to reconnect manually. In both these cases the
connection is usually back within 5 seconds (very rarely I have to do
this twice).
I have reinstalled network manager and resolvconf, I have disbled
ipv6, I have edited NetworkManager.conf (along with a few other things
that all don't seem to work). Generally the connection is stable for a
long time following a reboot, but once it starts dropping out, it can
stay stable for a half hour, or 2 minutes, and there seems to be no
way to know.
Sometimes trying to load a page or an element in a page will trigger
network manager to react to the loss of connection. What I mean is
that in this case both skype and dropbox show that they have gone
offline, and the network manager icon appears to look for a
connection. This then happens within 5 seconds (as when I do this
manually) and the connection is back. Again, this then can hold for a
half hour or only 2 minutes, or anything in between.
