SB 6120, 6121 and 6180. All work well with the R1 with my ISP. I'm looking into getting a Motorola MB series next.
Even though you claim to have tested all modems, I highly doubt you can test all modems with the R1 on all ISP services. Each ISP is a bit different in there services.
Not here either to claim only one specific modem works, however in recent posts you have trolled and seem overly biased against people who claim other modems DO work. Even against me and you continue too. Thought people say there modems work and you don't seem to believe them, maybe the sky is blue and there speaking the truth. Why not accept them or what they say. Were all there to gain knowledge and express our experiences, not pass doubt or lie about things. Maybe those modems do work and are working. Why is that hard to believe huh?
It would be in NetDumas best interest to make sure ALL or as many modems work well with there R1 modem as possible, not just one or a few. Again, not all ISP services support all modems or your TPLink modems which you seem to favor and push on others. Of course if the ISP supports it, of course, try it. However if users are seeing good experiences with what you claims doesn't work well with there R1, then doesn't mean any else accept that it's working for them. Users of the R1 shouldn't have to try other modems to get good experiences with the R1. Your list is misleading and inaccurate. It should reflect what works best with the R1 in your experiences however other modems will work and depending upon ISP services, bandwidth usage, cabling, signal and line quality and router configuration can and will effect how the modem, R1 and gaming experiences are seen. Also other modems could be recommended for ISPs that don't seem to support your favorite modem Mfr.
The list would be also out of date as time goes on, the last time you supposedly tested the modems, new FW version have probably been released and may have improved how the modems work with the R1, or could have made it works as well. Have you tested ALL modems again across all ISP? LOL I doubt it.
Over all, you could be a little less biased and be a bit more encouraging with people who post there experiences with other modems besides TPLink and regardless of what modem they are using. As time goes on, 8x4 and 16x4 modems will be going away and DOCSIS 3.1 will be the norm, things will be changing as well as the R1 and there OS which we are patiently waiting for.
I have though. Multiple different modems with multiple setups, speed plans and locations throughout the country. Only the modems on the confirmed working list are ones that work under ALL conditions. Which I have meticulous gone through trying each individual setting and option to purposely break things.
For example, a SB6141 SEEMS to work fine. Until you enable super turbo mode. But I really don't have to explain myself to you. If I said the sky was blue you would try to argue differently.
Have YOU used any other modem besides the SB6183? No.
