AE vs BBOX2

Hello,

I have experienced problems with my network configuration lately. Before it worked rather nice and I didn't change anyhting.

This is the set-up at this moment:

- Proximus Bbox 2 modem >> wireless turned off

- Airport Extreme >> bridge mode

- connection between Bbox and AE through the LAN port

- Proximus TV connected to the AE thourgh LAN

I get a green light on the AE and I have fast internet when I connect my laptop with a cable to the AE. When I disconnect the cable, the connection fails and says I gave an "invalid pasword". I did try for several times.

I can't set up the network connecting modem & AE through the WAN port, because then I have no TV.

Can somebody help me out here?

Thanks.
