Wifi Issues with random disconnections to all devices connected to Wifi

[Trekian]

We used to have few issues with Wifi connection apart from the occasional drop out. 

We have a Talktalk Wifi Hub version SG4K100206, firmware 3.

The master socket is in a front bedroom on the window sill. The router is plugged directly in to the MS. 

For about the last 8 weeks we have had disconnection issues to all devices. There are 4 of us with a phone, tablet, laptop each, 4-6 smart plugs, smart TV, and 6 Echo devices. The echo devices regularly announce 'unable to reach the internet'. 

We have carried out all of the normal trouble shooting, such as rebooting (all devices), even resetting the echoes. We have moved the router around as far as the leads will allow, but this does not seem to make any difference. Obviously, most of the time we are downstairs with the router upstairs, in a diagonal line of contact. 

I also tried changing DNS to Google but this did not help.

I added a TP Link plug-in extender, but that also does not solve the issue. 

I would be grateful if @KeithFrench could help me with this as it is likely to be as he says an interference issue.

Your help would be appreciated.

Kind regards 

Ian

Hi @Trekian 

No problem. Slow speed, intermittent dropouts, breaks in the signal or no signal on some or all devices or no internet access might be caused by Wi-Fi interference from other local networks, which can also lead to a permanent reduction in speed. No ISP can be responsible for your local environment, this is mainly a byproduct of the popularity of Wi-Fi.

Generally speaking, the 2.4GHz band suffers a lot more from interference than the much faster 5GHz band, but the 2.4GHz one can sometimes have a better range, but this all depends on your local area.

Do not worry about interpreting the results, I will do that for you. I will send a PM to you that contains a link for a guide of mine on Wi-Fi interference. It is quite long (about 30 pages), but you will probably only need to look at three or four pages in total. Initially look at the section called "Are you suffering from interference – prove it first". This is the first link in the table of contents. This section includes full details of free Wi-Fi analysers that I recommend for Windows, Windows phone, Android and Apple operating systems. However, I have no way of testing the Apple product. Select the analyser of your choice & my guide explains how to use it.

If you are using Wi-Fi Scanner, then please attach the zip file to this thread. As soon as I have downloaded it, I will remove the attachment from your post, to preserve your privacy.

With all other analysers, please follow my instructions below.

Collect the screenshots that I require and include them in your reply.

Please post the screenshots to me in a PM (to protect your privacy), which I have requested in my guide. No photos please as they can be difficult to read, because the text can get out of focus when zoomed in. Please ensure that the analyser window is maximised (if Windows) before taking the screenshots & upload them via the "Insert Photos" button (in a mobile browser it's the picture icon) on the post editor's toolbar with the Size parameter set to Large.
