Trying to understand BQM report

Hi all,

A non technical person asking a question here

 

I have a 200mb hub3 setup.

The wifi for about 5 yrs.  In the last few months the wifi signal started to drop, an engineer came out and replaced the router with a hub 3.  The signal still kept dropping out a few times a day.  I read that the router is a low quality one and upgraded to google nest.  the wifi service and speed was instantly better.  but in the last few weeks service does seem to drop on wifi and ethernet connected devices.  I was advised to use think broadband to monitor the service.  It did not work with the google nest so over the last few days i reset the hub3 to do both modem and router functions.

I would like someone to advise on what the report is saying, is this something that i can send to VM to look at their end?

 

hub 3 bqm 

 

thanks

 

Andy

Re: Trying to understand BQM report

The BQM needs to be read in conjunction with other data.

 

Lets start with the basics ...

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.

 

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: Trying to understand BQM report

The imac running the BQM is located in the same room as the router ad is connected by an ethernet cable

Re: Trying to understand BQM report

Hello

There is one other thing that can de done, as looking at the Post RS errors these are quite high, I would go around and make sure that all the coaxial connections are finger tight to all VM equipment, the best way to do this is too loosen all connections and the re-tighten, once that is done power off the hub for 30 and then back on.

If then when checking the  downstream and your post RS errors are increasing at a large rate then an engineer will be needed to find the source of the noise as Post RS errors are indicative of noise or other connection problems between house and street cabinet.

Re: Trying to understand BQM report

no service issues on the link or the phone number,

co-ax connection was able to be tightened in the router a half cm turn (finger tight)

Re: Trying to understand BQM report

Hi Andybud, 

Thanks for your post and welcome to our community. 

I'm sorry for the broadband issues you've been having lately and for the delay in getting back in touch. 

I've tried to have a look at the services from here and see if things have improved since your post but I've been unable to locate your post. 

Hopefully things are all sorted now. If not please can you reboot the hub and let us know, we can then pop you a message and do some further checks.
