Question : wireless router with DSL router

I first connected to the internet via a cable connection. I had a wireless router which also has a printer port and that worked fine. So I had the wireless router connected to the cable and my printer connected to the wireless router.
Now I got a DSL router from my work so we had to switch to a DSL connection in stead of a cable connection.
If I only use the DSL router everything works fine but the thing I can't use my printer now unless I hook it up directly to a PC. (which I don't want to do because no space).
So I want to use my wireless router too so that we can use our printer AND on top of that have wireless connection.
But I can't get it to work...
Any ideas?

Answer : wireless router with DSL router

Just FYI, I have a similar setup running in my home, and use a regular cable to connect the router to the wireless router (As opposed to a crossover) from one of the 4 LAN ports of the router to one of the 4 LAN ports of the wireless router.  With DHCP disabled, most routers will work with regular ethernet cable between the two LAN ports because the signal is swapped inside the router when it passes the info to the wireless access point, print server chips etc. inside.  Also many, if not most of the little small office / home wireless routers you buy these days will auto-sense the input/output signal and adjust accordingly.  In a nutshell, some will require a regular cable, some will work with either, and some will require a crossover cable.  I just wanted to throw that out there so that a) you try a regular one before you rush out and buy a crossover, and b) if one doesn't work, you know to try the other.
