Low speed unless hub restarted

I had my m500 installed yesterday. When engineer left the hub restarted on its own twice. It hasn't (that I'm aware of) since.

 

Last night I noticed I was only getting 50mbps download speed. I tested wirelessly and wired.

I then manually reset the router using the pin hole on the back and tested again. This time I was getting around 450mbps. 

I have tested again this morning and was roughly 350mbps. Then again just now (15.15) and I'm back down to 50mbps.

I have reset the router again using the pinhole button and tested speeds again. Now around 450mbps.

 

I believe I may need an engineer to attend as it seems like noise may be knocking some channels off therefore losing speed?

 

Thanks

Re: Low speed unless hub restarted

It can be difficult diagnosing problems without some basic information.

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 the area. Be aware that it isn't a manned line.

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

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

 

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 can 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.

Then

 

Can you please

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

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

Copy and paste the contents of the Downstream, Upstream and Network Log tabs onto here, if you get a yellow warning click the Post button again.

A Guru will be along soon to decipher the info.
