Ongoing broadband issues

Sorry if this is on the wrong board but I’ve been having issues with my fluctuating broadband speeds for quite a while now. I checked the network log on the router status page and noticed a lot of critical errors that keep occurring pretty much daily.

from what I’ve read it could be due to the power levels being abnormally high (or low as the case may be).

can anyone please confirm this and help me with a potential fix please

Re: Ongoing broadband issues

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 more 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 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.

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 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 and Network Log tabs onto here, if you get a yellow 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: Ongoing broadband issues

I keep getting dropouts all the time and even with a wired connection I get 44mbps and occasionally jumps to 100mbps. Bit of a bummer when you pay for up to 200mbps if that makes sense.

surely all those critical and warning messages in the log mean something isn’t right??

Re: Ongoing broadband issues

Hi Gregerz85, 

Thanks for your post and welcome to our community. 

I'm really sorry you've been having some on going broadband issues, this isn't what we like to hear. 

I'd also like to apologise for the delay in getting back to you, we have been busier than normal. 

 

I've had a look into the back end of the services and we've identified a short term network issue that could cause degradation or an intermittent service. 

We believe it will only be a short term issue and it will be fixed very soon. However, in the mean time, it would be great if you could check that the coax cables are connected securely to your equipment, any splitters (standard and powered) and to the wall socket.

Let us know how you're getting on with things.
