Over the last few weeks I appear to be having issues with the WiFi. Constant disconnections and low speeds, but no issues with the wired connection. It happens on all of my devices and I've tried changing frequency resetting etc but no luck. I can be 1 meter from router and I can't connect or when it does connect, I get extremely slow speeds.
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 on each of these routers and on the HG633 you will need to additionally 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.
With the May 2019 feature update to Windows 10, some older computers may experience loss of Wi-Fi connectivity due to an outdated Qualcomm driver. Please see this from Microsoft:-
I have followed the advice, no new equipment to cause interference and I have tried connecting via the difference frequencies, I have reset router but the issues remain, I can have my phone, tablet or laptop within 1 meter of the router and I lose connection or get very poor speeds less than 5 mbps but getting over 70 mbps via wired connection.
I did say in my previous post that it fixes nothing as yet. This is too complex to deal with in one post. The next stage involves proving what the problem is & hopefully fixing it. If you want my help with this, just let me know.
speeds and loss of connection suggest that you would be far away from the router as usually this would only occur with a weak signal, but as you said you are in the same room and nothing has changed i would say the router is at fault and you need a replacement
That would only be the case if their WiFi configuration was identical, did you check that?
The only thing that I have done it trying to connect on the 2 different frequencies. Both routers are as supplied from talktalk. My uncles work fine, mine does not, it was fine until recently. I have not added anything that could interfere, changed location or changed any setting.
It is very unlikely that the router is at fault. Please look at my post #6, where I have offered you help to fix this and let me know if you want my help.
