Router keeps disconnecting devices from wifi

Hello my fibre router is disconnecting wifi on various devices at intervals.  When you try and reconnect it says the password is incorrect.  If you try manually it says the same.  I will then restart the router and it connects the devices ok.  After a short while a hour or so it drops them again and the process starts again.  This has been happening for about 3-4 days.  Has anyone any ideas?

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

Go to:-
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.

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.
