There's a way to switch a telus router into passthrough mode. This essentially makes it the same as a regular modem from shaw. Of course, I can't remember what the setting is for it.
I just switched back to telus from shaw, and this time around I told them to keep their crappy "router" and just send me a little black passthrough modem. Their routers are a waste of time. They're also a waste of money, and they're free, so that should tell you something about them.
Edit: Whoops. Didn't see Ken's post about the firmware update disabling the passthrough setting. Even more reason to treat their "routers" like the second coming of the black plague. Well, the black plague + some sort of modern-day medical amnesia... Otherwise the black plague probably doesn't sound very scary...
