I'm replacing my sbg6580. It's been good to me for that past 5 or so years but it's starting to fail. I'm wondering if there are any advantages to having a separate router and modem? I am looking to spend about $130 on a new combo unit. Can I get a good modem and seperate router for that price? Is it a pain to configure the units separately or might I get more customization that way? And does anyone have suggestions on modem router models you guys use together? I only have 1 wired component. Everything else is wireless if that matters. And I'm obviously looking for the max bandwidth I can get. Thanks in advance!
