Slow speed, intermittent dropouts, breaks in the signal, or no signal on some or all devices, 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 by-product of the popularity of Wi-Fi.
However, other factors should be investigated first. When this happens, what are the lights showing on the front of the router? Do you have any wired connections & if so, how do they perform?
If you have the HG633, HG635, DSL-3782 or the TalkTalk Wi-Fi hub, they are dual-band routers & offer both the older 2.4GHz & the newer 5GHz Wi-Fi bands. The problem is these are two different networks (SSIDs), but they share the same name, so you can't tell which one you are connected to. Log into the router (http://192.168.1.1) and enter a username of "admin" and if the HG635 a password of "admin" as well, or if the HG633, DSL-3782 or the TalkTalk Wi-Fi hub, use the unique router password (see the label on the rear of the router at the top).
HG633/635 go to:-
"Customise my wireless network"
Append "5G" to the end of the network name of the "Wireless 5 GHz SSID" field. Then click "Save".
DSL-3782 go to:-
Settings > Wireless (Wi-Fi)
Append "5G" to the end of the network name of the 5 GHz "SSID" field. Then click "Save".
TalkTalk Wi-Fi hub
Dashboard > See Wi-Fi Settings > Manage Advanced Settings > Wi-Fi 5Ghz gear icon > Basic
Append "5G" to the end of the network name of the "SSID" field. Then click "Apply".
This will not fix your issues, but it will make it much easier to identify the band you are connected to. This way you will know which band is causing your problems.
Having said that, there is another approach which can be better, which is to use Band Steering. This will automatically move any 5G compatible device connected to the 2.4G band to the 5GHz band. This is available on the HG633 (V2.00), DSL-3782 (V1.10) and the TalkTalk Home Hub. To use this leave both network names identical and on the HG633 enable Band Steering from the initial Wi-Fi menu.
Generally speaking, the 2.4GHz band suffers much more from interference than the 5GHz band, but the 2.4GHz one can sometimes have a better range, but this all depends on your local area.
You may then wonder what was really the point of this if it won't solve the problem? This is because the whole topic is too complex to be dealt with in one post. The next stage involves sending out a guide to you to help you get me some important diagnostic results, so as I can analyse them for you and recommend changes to your router configuration to solve them.
I only send this out to people who request it.
I am not surprised, please read the last two paragraphs of my previous post.
Please see my attached guide on Wi-Fi interference & initially look at the section called "Are you suffering from interference – prove it first". This section includes full details of 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. Do not worry about interpreting the results, I will do that for you.
Please post the screenshots that I have requested in my guide, from the analyser you are using (also in my attached guide). Please ensure that the analyser is maximised (if Windows) before taking the screenshots & upload them via the "Photos" button on the post editor's toolbar as large images. If they are too small, I will not be able to read them & although I can enlarge them, this just puts the text out of focus. If you prefer PM them to me. If you do PM me, then please add a link in there to this thread, so as I can find it easily.
We have been putting up for months now of constantly dropping out wifi signal and terrible range of the signal , won't even connect to tv which is in the kitchen ,router is in the hall about 5yds away, it has gradually got worse and we are sick of it now. You offer the new super hub to new customers on fibre and the customers who have been loyal for over 15 yrs have to put up with a older router which we have had for years. I would like a replacement router as sick of have to keep trying different things all the time just to get it work and when everybody is trying to access internet it usually kicks people off supposed to be paying for fibre so all 4 people can use it at the same time.
Have you tried getting me the screenshots so as I can help you?
I don't offer any router any routers because I am just a customer.
