Hi,

Post up your Connection details and someone will check to see if there is a problem.

In your browser’s URL box type in http://192.168.0.1  (or http://192.168.100.1 - if in modem mode) hit return.

On the first page click on the “router status” icon/text at bottom-middle of first page up and then copy/paste as “Formatted Text” (not images)

FULL sets of data onto here

pages from the Downstream

from the Upstream & the Network Logs page.

Mac, IP addresses will be blanked out when you submit and have to do this twice

Please also set up a  “Broadband Quality Monitor” to monitor the state of your connection and record any true network dropouts, latency issues, packet loss.

It will allow you to identify issues It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) post the “link” to the “share live graph” (as per instructions on the TB website) when it starts to develop.

Power levels look good however same can't be said for the Pre RS Errors Post RS Errors, would you mind giving us a hub reboot then submitting more stats later on?

Also meant to ask what your broadband speed is as from what i can see it looks like M350?

[maxwellmck]

To confirm it is a M350
and have rebooted now

I am getting slow speeds still Single thread 17:57

above is a thinkbroadband test file as you can see the speed is very slow

Nvedea driver downloads

OVH data centres download speed

[Roger_Gooner]

Your upstream power levels are too high and are quite possibly hindering download speeds.

[RR-IT-GUY]

thanks for spotting that, I had not.

You will need an engineer to check your tap to check if its good and you will also need to check how many splitters you have for TV services and make sure there are less. The cables should really be replaced and ideally the splitter should be replaced for a powered splitter if there are a few cable devices such as TV's however the downstream looks good so that might cause another issue? I'll let someone here see what they think.

Would someone mind flagging this up for the forum team to get an engineer booked.

Either its the way QoS is done in the area on VM side or you need to set this in admin cmd
netsh interface tcp set global autotuningl=normal
