Noisy Upstream Channels (32 QAM)

Hello. I need some technical help as i have an issue with my upstream, which is causing me to disconnect all the time from Xbox Live. I have all the necessary Xbox router settings changed to make NAT open and port forwarding etc.

So i was told by someone here to check my upstream and that could be causing the constant dropout? VM call centres are closed and I can’t find a way to chat online. I think i need an engineer to check the main outlet. Or what can I do? Thanks 👍🏼

Re: Noisy Upstream Channels (32 QAM)

Have you checked the 'Check Service Status' at the top of the page ?

If nothing is showing try phoning 0800 561 0061, this will tell you of more local issues that may be affecting your district. Be aware that it isn't a manned line.

Go round all the accessible internal and external co-ax connections and ensure that they are finger tight.

If everything above is OK we need do some more troubleshooting; to start with …

Disable any VPNs that you have running.

Can you set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you should post the link straight away.

Post a 'Live Link' to your BQM on here.

Instructions for posting BQM Link

Under your BQM graph are two links in red.

Click the lower link (Share Live Graph) then click generate.

Copy the text in the Direct Link box, beware, there may be more text than you can see.

On here click the Link icon (2 links chain to the left of the camera icon)

In the URL box paste the link you copied and in the ‘text to display’ box write My BQM then click OK - you can post the link straight away.

Then

 

Can you please

Type 192.168.0.1 (192.168.100.1 in Modem mode) into your browser URL bar and press enter. 

Hub 2 & 3 When the page appears DO NOT LOG IN but click ‘Check Router Status’.

Hub 4 When the page appears LOG IN then click ‘Check Router Status’.

Copy and paste the contents of the Downstream, Upstream, Configuration and Network Log tabs onto here, if you get a yellow / straw box warning click the Post button again. Use one post for each tab if you wish. Please do not use screen grabs.

A Guru will be along soon to decipher the info.

Hello Mike,

Thanks. Yes I've gone round all the coax and wired connections, all snug and tight. I just had another Xbox Live dropout again and it stops me from playing.

Here is the link to my BQM I set up a few days ago.

Re: Noisy Upstream Channels (32 QAM)

I've just noticed that the upstream is now showing 64 QAM on all accounts. Why would my Xbox still be losing connection every hour or so? Thanks. This is driving me up the wall!!

Re: Noisy Upstream Channels (32 QAM)

There is nothing jumping out as a problem on your Hub data or Network Log.

Your >> BQM << is looking OK apart from the red at about 19:15 yesterday, was that a reboot by any chance ?

Hi Mike. Yes that red part was a router restart last night to see if that did anything. Super strange, all my other devices don't have an issue except the Xbox One. I've given it a static IP and done the port forwarding, could anything else help? I used to have VM 5 years ago and this issue was always a problem. I fixed it but it took so many ways to do it and i can't exactly remember how. Thanks
