Time Capsule + modem advice (arris?)

Hi all-

Looking for advice on a new setup, with particular care given to the Arris SB + Time Capsule debacle.

My current setup:

TWC 100mbs + Arris SB6141 + Time Capsule.

Worked great (guess I was lucky) for a year, then moved and upgraded internet. Now I get the flashing yellow and DNS errors, with no luck resolving as I had before.

New setup (not working):

TWC 200mbs + Arris SB6141 + Time Capsule.

Not only can I not get this working, but the SB6141 won't support up to 200mbs as I understand it. So I need to make some changes to the modem regardless.

My questions is:

Here's where I need some help. What's the ideal setup in my situation? I think I have a few options with some questions:

1. I buy a new non-Arris modem. Does anyone have any suggestions for what would work well in my setup?
2. I buy a new Arris modem, like the SB6183. Does that work with TC and better than the 6141?
3. I buy a new router and a new modem and use the TC in bridge mode (<- think I got that right)? Any suggestions for a new router if people think this is best?

Any thoughts on how to best proceed? I work with video fairly often for work, so ideally get this worked out. My other devices are a couple macs, an apple tv, phones... nothing crazy.

Thanks!
