Thanks a lot for you rcomments - I have tried the extra hub and voila - works. So it is some sort of physical missmatch - I never had this before. Lession learned
I didnt know Linksys stuff is so bad, I was under the impression they are OK, I have three AP's/routers in my house, Tekram, MBO and Linksys, and the Linksys was the only one I never had to reboot since of hangs, so I thought the gear is good, but the WET11 seems bad as u said.
Firmware of the bridge I actually updated first to latest release - no change.Seems to be physical.
I will actually run the (functioning) MK2 over the WET11 for a few days to see how it goes, then I will install in the car eventually.
Thanks a lot for the help and to shed some light
Take care, S.
