My ethernet connection is very slow (it was also with 11.04). It works fine with another PC with XP. Also, WIFI is OK in Ubuntu.
I've checked several help pages, but nothing seems to work:
The connection is slow for the Update Manager too, so the Firefox settings I changed obviously did nothing.
It is not the IPv6 (set to Ignore) either. The IPv4 method set to Automatic (DHCP) doesn't work at all. In manual method, with addresses and DNS copied from my other computer:
DNS servers: 18.104.22.168,22.214.171.124
It establishes a connection but then it is really slow. Sometimes it works fine for brief periods of time, then stops again.
I also updated the BIOS.
... and also installed bind9.
I'm connected to a apartments building's connection, so I don't have access to the router, etc.
The ethernet controller is Atheros AR8152 v2.0 (rev c1). At the network information it says that the driver is "atl1c", which I also updated (or installed, I'm not sure now).
My wife is getting really pissed off and I don't know where else to look.
Any help would be appreciated.
