Solved Router + router on one adsl line, possible?

[micho0305]

HI there, greetings from Croatia!
I need some help here. I this possible (picture)? If it is, where I have to input LAN cable from Thompson router to Siemens router?
Here is the problem: In my home there is 3 PC, 2 laptops, 4 mobphones. They are all on Thomson, LAN or WiFi, everything is working fine. But.. Yesterday I manage to repair older PC (PC2 on the picture) for daughter, and encountered to a strange problem. PC is working fine ( celereon 2.8 occ, 2GB RAM), but WiFi is not. I have 2 wifi adapters (Siemens&Realink), tested them at others machines, they works. Normally, password, user name, whatever.
Then I passed through The Calvary- installed XP media centre, XP black edition, Vista extreme, Win7, -same problem. LAN is working but WiFi finds router signal, try to connect and falls without explanations(like connection is out of something, or password is incorrect). I tried with installing original Siemens and then Realink software, installing just drivers, didn't help. Don't know what to do next. Maybe somebody here know? Any help will be welcome.
So, I will try to solve this problem by adding one more router so PC2 can connect to Internet via LAN. Is it possible?
Thanks everybody for reading such a long post.

Maybe you didn't realize this but both of those router's aren't actually router's, they are both modem/router's which means you can't use them together. The secondary router needs be a regular router not a modem/router.

Thank you for info. So what I have to do? Can I establish any connection?
EDIT:
Well I tried. And it works. As sec. router I connected d-link dsl584T (not wireless) to LAN1 port, pc1&pc2 to LAN 2&3. In the beginning PC2 didn't work becuose LAN3 was ment to adslTV connection, but I found small hack(unlocking) software wich helped to LAN3 become "assigned" to PC.
Hope somebody will find this usefull..

Yes the D-link is an actual router. Connecting LAN port to LAN port is correct however,...you need to go into the D-Link and disable DHCP or you will run into problems. You only want the first modem/router to be handing out IP's via DHCP, not the second one.
