What is the highest performance modem I can purchase for Suddenlink 1GB service?  I have an ORBI AC3000 router, but also looking at the new WiFi6.  Thanks for the advice.

What ever the ISP supports will be suggested. Modem with out a built in router as well is recommeded. 

NGs CM1000 or CM1100 or CM1200 would be recommended. If you ISP supports them. You'll have to ask them about those models.
