Slow Upload Speeds

Hi!

I hope everyone's enjoying their slow return to normality (whatever that is!)

Would appreciate some of you brain boxes having a look at these status pages and seeing if anyone can figure out why I'm getting such excruciatingly slow upload speeds (with a wired connection) on a line that's meant to be getting 100/10

Please let me know if there's anything else that would be helpful to see.

Thanks

Chris

Re: Slow Upload Speeds

Re: Slow Upload Speeds

what speeds do you get wired direct to the hub without the other router connected?

Re: Slow Upload Speeds

Sorry for the delay getting back.

Exactly the same speed and stats when connected directly the the Super Hub. They obviously fluctuate but download has been hoving around 20-30 mbps and upload has been around 0.6 - 0.7 mbps

Re: Slow Upload Speeds

run cmd and
ping -t -l 1472 194.168.4.100
run a speed test and when it gets to the upload speed what speed did you get and did your ping spike.

Re: Slow Upload Speeds

Seemed to be averaging around 20-30 ms before speedtest, and then around 100-110 during the upload part of the speedtest

Re: Slow Upload Speeds

Test again this time with ping -t 194.168.4.100

From the looks of it your buffering in the modem below your upload speed limit as the CMTS tries to give everyone some bandwidth for sending.
