Slow Connection

Hi, I have been facing extremely slow speed both with a direct connection and over the wifi from my Hub. The speed I should be getting are 600mb but don't even get over 50mb and even the upload speed is slower than what I used to get. This has been happening for a while now so could someone help me with this issue please.

If need to check something from the Hub setting than can you please give full instructions as I don't know much about it.

Thank you.

Re: Slow Connection

Can you post your Hub status and logs?
Someone should be spot if there is a problem
Navigate to http://192.168.0.1 (or http://192.168.100.1 - if in modem mode)
Don't log in!
Click on 'router status'
Copy/paste the data from each of the tabs. The forum software will remove the MAC addresses for you (you may need to click the 'post' button again). - Also use 'Reply' as opposed to 'Quick Reply'

Also, set up a 'Broadband Quality Monitor'. This will monitor the state of your connection and record any network dropouts etc - You can do this at ThinkBroadband (https://www.thinkbroadband.com/broadband/monitoring/quality)
Give it a while to gather data and then click 'Share Live graph' and paste the 'Direct Link' into the forum!

Im trying to post the Network Log but it's keeps giving error "Correct the highlighted errors and try again." and not letting me post it.

Running late so will set the network monitor later but how long would I need to run this for?

Thanks.

Re: Slow Connection

Thanks for that - the issue here looks pretty clear - there is massive noise ingress all over the place!

Can you check that all connections are finger tight.

The network log may have to go in a different 'reply' as it is very long - also when it says correct errors and try again - just re-hit post as this is the forum software removing MAC addresses!

Also, you have only 1 upstream channel on a massively too high power!

VM need to book a tech visit if you are not being impacted by a wider outage (150 from a VM phone or 0345 454 1111 from any other can tell you if this is the case)

Basically the RxMER values should be above 34 IIRC - if you look at the channels with the highrst number of PostRS errors - The RxMER is far too low indicating a loss of signal / poor signal!

Re: Slow Connection

While checking the cables on the HUB i noticed they had connected a "Forward Path Attenuator 3 dB" to the broadband cable and than connected both to hub. I removed this bit and than check after and my speed had improved. Below is the new router status report after remove the bit.

Re: Slow Connection

Ok - That has sorted your D/S by the looks of it - at the expense of your upstream (I think the noise was a loose connection or a faulty attenuator!

As your upstream is totally borked now: Can you power off the hub (at the wall) for 5 minutes

Turn it back on and wait 10 mins for it to stabilise - See if that resolves your U/S problem!

Re: Slow Connection

Hi fatimaibrar,

Thank you for reaching out to us in our community and welcome, I was able to locate your account with the details we have for you and have detected a connectivity issue, please can you check all internal connections are hand tight including the wall socket, and splitters and all equipment, try unscrewing then putting back on just to make sure all is connected correctly?

Regards

Paul.
