That is what I did. No ping answer, whatever the IP or DNS. Just as if I
was not connected. But my router is still connected to the WAN, and the
router is still connected to the LAN.

I tried too, sorry. :-(

You mean that I should try others DNS servers from my ISP? What would it
change? I shall try, but I need to know their IPs.

Hmph...

Before opening the pages, start capturing packets (using wireshark
if you must, or tshark from the CLI).

Your symptoms *probably* happen to me, but I just accept it as part
of Firefox's poor threading.

For example, if I "kill -15" the Iceweasel pid then exit the GUI to
apt-get upgrade and then restart xfce and Iceweasel, all the (4 or
5) windows and (total of 20-50) tabs restore. It takes 3-4 minutes
for all of them to complete loading.

I will try this.

That is a good example of a massive tab load. If I have so many tabs
opened, and that I kill the resp. pid, I can restore the tabs, just as
you do, and then the whole connection stalls. Nothing loads, and each
URL keeps its name, not the page's title.

Ugh.

Then the origin of the problem can be in the router itself.

Look into the router's options (QoS, firewall settings, logs...) to check
if you can tune some of these parameters.

It happens to me very frequently that the router NAT tables are filled up
and momentary I loose Internet connection. This happens in a local
network with many clients (a busy router) but I won't discard something
similar is happening here.

Also, search into the manufacturer site for a firmware update.

You can also test with another computer connected to the same router to
see if it happens the same and so discard any configuration problem in
the machine.

If a ping does not work, it's a bad sign (I mean, not a DNS issue).

Anyway, yes, you can use whatever DNS server you want, they do not need
to be the ones your ISP provides.

I.e., you can use openDNS public servers (208.67.222.222-208.67.220.220)
or Google's ones (8.8.8.8-8.8.4.4).
