then we use his IP address (in PSE-B) as our default gateway (from PSE-A)
he can launch wireshark and see what is going on

I also changed the default gateway of both radio bridges (192.168.1.10 and 192.168.1.11) linking PSE-A with PSE-B to point on 192.168.1.14
But still without a result

Then it must work
I do not see why it will not work afterwards

We changed the cabling to a central switch, it did not solve the problem.
Setting the vtx device into bridge mode with a linksys spa3102 as router did not solve the problem, neither shutting down the swisscom router.
Kerim proposes to try by inverting the direction of the wifi link.
Christian thinks of some strange network problem (MTU mismatch or packet fragmentation on the wifi link), but it should not cause problems with ping.

Christian, Kerim,
I suspect that the strange problem comes from the fact that in PSE-A the Swisscom router is a kind of a central switch. Offices and other switches are interconnected via the switch integrated in this router. All cables of different parts of LAN shall be connected to a neutral switch. The Swisscom router must be also connected to that neutral switch as an appendix (no other LAN part must transit via Swisscom router). I hope that after this, the problem will be solved.
Please do it, maybe today, because anyway the day is lost due to STEG

This doc must be updated once the LAN works properly
- add the missing screen shot with the VTX in PSE-B
- add the diagram of our network [gw EPFL] -- [gw VTX] -- [gw Swisscom] --- LAN PSE-A [bridge] ---- [bridge] LAN PSE-B --- [gw VTX]
- specify the connection parameters (upstream/downstream/monthly fees)
