"Cannot connect to network" on 2.4GHz

Conversation Starter
Message 2 of 2




I have a Sagemcom TalkTalk WI-FI hub and am having trouble connecting to the 2.4GHz network from my iPhone 12. I get the above message but instead of the 2.4 it gives me the nameof my SSID.


I have looked at older articles and changed the channel to 1 and made bandwith 20MHz. I have rebooted my iPhone and still cannot connect to the network. It is just my phone. My laptop and my iPad will connect with no issues.


Why do I need to connect? Because I have Wi-Fi plugs on the 2.4 network and need to connect my phone in order to manage them or add new devices. 


Please advise.


Many thanks

The problem is that you do not know how good channel 1 is.


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.


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.

Have you had TalkTalk’s Wi-Fi optimisation disabled on your Sagemcom FAST5364 router? When this is enabled, as it is by default, it has the power to override any Wi-Fi configuration changes that I might suggest that you need to make. This will not help rectify this type of problem if Wi-Fi Optimisation is allowed to change my suggested settings. Only TalkTalk can do this for you, you cannot do it yourself. If not, just request they disable this for you in your reply.

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 employed by TalkTalk, I'm just a customer. If my post has fixed the issue, please set Accept as Solution from the 3 dot menu.
