SLow speed with interruptions on M350

When I first upgraded to M350, I was getting this speed and above most of the time.  I have not seen anything above 200 Mb for weeks and I am getting frequent interruptions, which causes drop-outs in online meetings.

Re: SLow speed with interruptions on M350

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.

++++++++++++++++++++++++++++++++++++++++++++++++

Your Pre & Post RS Error counts are very high.

In an ideal world they would be at zero and stay there. To zero them can you reboot the Hub using this method and then keep an eye on the counts.

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 the counts again.

++++++++++++++++++++++++++++++++++++++++++++++++

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 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.

Re: SLow speed with interruptions on M350

Hi Grindathotte,

 

Thank you for your post and welcome to the community. 

 

I'm very sorry to hear about the slow speed issue you're having. 

 

I have taken a look on our side this does need further investigation. 

 

To assist with this I will private message you to get some details. 

 

^Martin

Re: SLow speed with interruptions on M350

Hi there @Grindathotte

 

Thanks so much for your Private Messages to @Martin_N; sorry to understand that you're having some issues with your broadband and having some slower speeds than expected. 

 

After having a look at your account from this end, I can see that you rebooted around 10 hours ago. We have no known area issues showing at the time of writing today and also no errors showing on your Hub. 

 

All signal levels are well within the parameters we would expect for your package.

 

Have you been able to do the BQM as suggested by our user @MikeRobbo so we can see if the drop outs are showing there at all?

 

I do see that you are currently using the Hub in Modem mode; do you have the same issue if you have the Hub in Router mode?

 

Please do pop back when you can and keep us posted. 

 

Cheers

Re: SLow speed with interruptions on M350

Thanks to all who have taken the time to answer.  It does not appear to have been so bad lately and as I have been very busy with work, I have not really had a chance to follow it up.  For some reason, when I check the speed with fast.com, it shows less than 200 Mbs for the first few times, then goes up to 350 and sometimes higher.  I did note that when transferring large files by ftp from work, I was getting speeds approaching 350, so maybe the problem has cleared.  Thanks to your responses, I have a line of action to pursue if further problems occur.

Graham.
