extremely slow upload on M350 connection

this has lasted a few weeks - gone from getting steady 35mbps up to between 2-5mbps. have called support several times, but have had to be on hold more than an hour both times and they haven't been able to help. suspect it may be related to this user's issue as we're likely in the same area, but who knows?

everything's wired, and am getting this same issue while directly connected to the router in router mode, though i usually use it in modem mode for obvious reasons.

this was my info before a long (5 minute pause) restart - can see a couple of channels that i think are out of modulation, and a bunch of T3 timeouts, but then this had been up for about a week or so.

EDIT: oh, and it might be useful to share my broadband quality thing, so here it is. i only signed up today and then restarted the router a couple of times, so it's not going to be very useful for a while, apologies.

Re: extremely slow upload on M350 connection

Hey toypadlock,

 

we're really sorry for our delayed reply from here, and for the speed issues you've been experiencing recently. 

 

I've been able to locate your account and have found that you are currently being impacted by an SNR issue in your area, which is estimated to be resolved on 17th November.

 

Please keep us posting with how things are from Tuesday and let us know if you need anything else from us in the meantime. Sorry for any inconvenience caused.

 

Kind regards,

 

Beth

Re: extremely slow upload on M350 connection

Thanks for your response. I wanted to wait for a few days to see how stuff was going before replying. While speeds are very occasionally reasonable, they're super variable and I'm currently getting an upload speed of around 5-8mbps. It's definitely not fixed, I'm afraid. Is there anything that can be done?

Re: extremely slow upload on M350 connection

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.

Re: extremely slow upload on M350 connection

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.

Your Upstream Channel Modulations are all at 64 QAM, they should be at 64 QAM.

You can try a reboot to see if it helps, it may or may not.

Switch the Hub off using the small switch on the rear of the Hub next to the power cord and pull the PSU plug from the wall socket.

Give it a good 5 minutes put the plug back in and switch the Hub back on.

Allow the Hub a few minutes to fully restart then check your connection again.

In which case you'll need an engineer visit to investigate further, unless there is currently a local area issue.
