With this occasion, I realized the original contents of the NVRAM had been corrupted and it contained only gibberish.
I used a dump file from somewhere here on the forum and, voila, network connectivity now works like a charm.

I have to do the same for my 3034, which dump file did you use, I can only find an nvram dump for the 3014 ...
are they compatible ?

sicco:
If i remember right then the NVRAM can be reset to factory defaults by pressing B-Trigger on front panel while powering up. The only thing that is not set then is the Ethernet MAC address. That’s because MAC must be unique for each unit.
As mentioned earlier, the MAC is stored in six bytes, and located at DS1728W address 0x6F0. The first three bytes must be 0x08, 0x00, 0x11, the next three you can pick randomly provided the same values are not used in the same network by other equipment.

You’ll need to run all the calibration utilities so that scope inputs DC offsets etc are good again.

ok nice to know, but it seems the B-trig on power up does not do anything. I still have my MAC (at least it shows in the menus)
Is the nVRAM format the same for all tds30xx models ?
After I did the "upgrade" to from tds3034 to tds3054, my network is not dead. I mean, it does get a dhcp address, but no printing and no escope anymore. Going to do the DSW conversion...
