Please help with Network Log results

[pineman]

For a month or more I have noticed that my in house WIFI is randomly dropping out. I noticed this on my iPhone where I suddenly have no access by WIFI to the internet. Often the WIFI symbol is showing but not working.

I thought, at first, it was a problem with my iPhone but exactly the same happens to my wife's iPhone at the same time. After a short while it resumes as it should and works ok.

This occurs in parts of the house where I have a WIFI extender and also right next to my Hub 3 Router.

I have tried restarting the Router and also resetting it but the problem continues.

I have interrogated the Hub 3 and the Network Log which is shown below and I don't understand the results.

Don’t post pictures, follow these instructions: 

How to get stats from a VM hub (no need to logon to the hub)

Open a web browser and go to 192.168.0.1 router mode or 192.168.100.1 modem mode

• Click on the “> Check router status” button
• Click on the “Downstream” tab, copy the text and paste into your reply, do not take a screen shot
• Click on the “Upstream” tab, copy the text and paste into your reply
• Click on the “Networking” tab, copy the text and paste into your reply.
• Do NOT post photos or screen shots they will be rejected as they contain MAC addresses. The board software will automatically change MAC addresses to **:** if done as above.

[Sephiroth]

Is there an attenuator (forward path type) attached to the rear of your hub?  I ,would have expected the upstream power to be around the 40 dBmv mark.  There’s nothing wrong with 30 dBmv on the upstream - the VM end commands the power it needs to successfully read the data.  Inn the absence of an attenuator, I would have expected the downstream power level to exceed 15 dBmv.

[Tudor]

Upstream power levels are too low and some T3s. Unless there is a local area problem you will need a technician’s visit to rectify. 

Check with Area faults on 0800 561 0061 If you have a VM landline 150 this goes down to post code level. You could also try the web page status, but this is not recommended as it only covers issues that affect a very large number of customers.

VM will not dispatch any technicians while an area fault exists.

If no area faults found:

The primary place to report faults or for service requests is Customer Services on 0345 454 1111/150 if you have a VM landline or wait two or three days for a VM staff member to get to your post.
