My new adsl ethernet router is TP-Link TD-8840, I don't see any options about connection limits.
It seems you're right, it's not just apt-get; Downloading anything big, like the package of virtualbox, using wget or firefox's download manager, results to error if I try to visit a website like www.google.com: "Address Not Found - Firefox can't find the server at www.google.com. - The browser could not find the host server for the provided address."
Hence the problem: can't resolve domain names.

This is backed up by the fact that while I was downloading, I tried connecting to an IRC server:
12:22:27 -!- Irssi: Looking up Elsene.Be.Eu.undernet.org
12:22:27 [Freenode] -!- Irssi: Looking up irc.ubuntu.com
12:22:47 -!- Irssi: Unable to connect server Elsene.Be.Eu.undernet.org port 6667 [Name or service not known]
12:22:47 -!- Irssi: Unable to connect server irc.ubuntu.com port 6667 [Name or service not known]
12:22:48 -!- Irssi: Removed reconnection to server Carouge.CH.EU.Undernet.org port 6667
12:22:48 -!- Irssi: Looking up Carouge.CH.EU.Undernet.org
12:23:08 -!- Irssi: Unable to connect server Carouge.CH.EU.Undernet.org port 6667 [Name or service not known]

The lag seems normal (4-5 seconds) while the download is in progress. It is uploading that deteriorates the lag or ping reply.
You could be right again about a driver problem. According to the network manager, my ethernet is using the r8169 driver. Oh and my ADSL connection is 512k/64k.
