High bufferbloat reading on download
With QOS enabled my bufferbloat reading on dsl reports is an F with massive ping spikes into the red. I installed the latest firmware. Speedtest on the router is measuring my download speed at 180 dow...
I'd be looking at my modem if you're tried changing routers and still getting the same issue.
1. What modem is it?
2. do you have a picture of your modems connections page?
3. If you directly connect to the modem and run the bufferbloat test, what results do you get?
- The modem is a netgear cm1000. I just bought it and I wasn’t having this problem with my old router. If I limit the bandwidth in my s8000 switch to 512 down and 32 up my dsl reports bufferbloat scores go to A+ As soon as I turn on any form of QOS on the router my scores go back to F. With the switch completely disconnected my download bufferbloat scores are F.
So a couple tests to try.
CM1000 alone:
CM1000----R8000:
CM1000---R8000---S8000:
Are you using qos of both the router and the switch? limit it to a single device controlling qos.
Any other monitors being used like traffic monitoring, parental controls, disney circle?
- Disney, parental, traffic meter are all turned off. If I use the QOS on the router and turn off all limits in the switch my bufferbloat is an F. If I turn off QOS on the router and adjust up limit to 32 and down limit to 512 in the switch I can get A+ bufferbloat readings. It just seems like my bufferbloat shouldn’t be so bad with just QOS handled at the router. And my speed is very slow. It seems more of a problem with download readings, upload isn’t bad. I have a gig down connection but through speedtest on the router it keeps saying my speed is only less than 200 down? And my WiFi speed is slow too? This is like Chinese algebra!
