CM1200 WAN aggregation slows down (requires reboot)
A few days back, I realized WAN aggregation was the only way I could get total bandwidth to use my 1.2gbs xfinity service due to the 1gbs ports on my CM1200. I successfully enabled WAN aggregation ...
What router do you have?
I don't have the CM1200 but I had a similar issue with an Arris SB8200 and the modem having issues. But I also had issues with specific routers improperly doing wan aggregation.
It could be the modem. It could be the router. Tough to know 100% unless you have a PC that has dual lan ports to go modem--->PC directly for a period
- I have the RAX120… and I noticed in the router conversation a two year old (long long) thread that this was happening for many people using different routers. Technically you’re correct, either side can loose sync, and even though the 1+1 connection is green… the sync layers from either side could prevent both ports from being used… using only port but now with the overhead of a failed sync layer.
How are you testing speeds?
Using the built in speedtest? If so, I wouldn't always trust that one as it doesn't always pick the best server to test from.
It could be the rebooting choosing a different server.
Just something to try next time it slows down
- Thanks. I am using the Netgear app on the phone. Certainty not pinpoint accurate! Lol… so no measuring for small changes. These are big repeatable changes which are consistent.
Before WAN aggregation… range was always 920-945mbs.
After WAN aggregation.. range was 1410-1440.
Like clockwork… after 22-24 hours… it just drops from the 1400mbs down to 800-840 …
Repeatable and consistent. After rebooting modem, back to 1400 for 22-24 hours.
I’ll keep looking otherwise, I’ll just have to disable, go back to my 940mbs … and wait for a good time to upgrade.
