Qwest only supports a handful of devices on their VDSL2 service, so converting the Q1000 to bridging mode as suggested by Bink is almost certainly your best option. That way the Q1000 is strictly used as a DSL modem, and all of the "heavy lifting" can be performed by the router of your choice.
I use a Netgear WNDR3700 behind the Q1000 with great results, and there are a few newer offerings with even better performance. Check out »www.smallnetbuilder.com/ ··· rts/view
