Orbi RBK852 & CM1200 Bufferbloat
I am in bit of a rough spot and cant find a solution for the life of me. I upgraded to gigabit line with xinifty (1000down 35up). Purchased the CM1200 and ORBI AX6000. I'm having constant buffer...
950down 45up wired through just modem and 950down 45up when the router is being used. Once the bufferbloat kicks in and speeds plummet to 25up and 25down the only thing that truly fixes it is resetting the modem. resetting the just the orbi router and not the modem will fix the speed issues with devices but not fully fix float/slow loading to devices etc. I have combed through these forums and seen your posts about toggling the 2.4 from auto etc etc and tried all of it... same issues. firmware 3.2.1.2.1.2.13 on both devices. I tried running the system yesterday without port aggregation enabled and same issues except my top speed would peak at 940down/35up and everything would crash back down to 25/25. with the cm1000 and r8000 I had consistent speeds speeds. when i got the orbi i used it with the cm1000 because the cm1200 came a few days later and these issues would occur. leading me to believe the culprit is primarily the router I think... but the issues dont get fully fixed unless i reset the modem and thats just temporary. right now since im using port aggregation the orbi is in router mode behind the the cm1200 just to be clear.
Ah ok. So there is a known problem with the CM1200 and LAG, users over on the cable modem forum have posted about the 1200 slowing down when LAG is enabled on a 1Gb service. I fortuneatly I removed my 1200 after receiving a 1100 which worked great on my 1Gb service. I didn't test LAG as I eas enjoying having two separate networks off the 1100. I haven't been able to put the 1200 back online to test it.
Please disable LAG on the 1200 for now. NG and ISPs are supposedly aware of this problem with 1200. I know the Orbi AX gets good speeds with my Cm1100. LAG disabled.
