Multiple wifi devices dropping off connection

[#1]

Hi, I wonder if anyone can help? (I have moved this post here to the correct place)

I have boradband and a plusnet router which has worked for years with no problems. Over the last couple of months both my wifes Iphone 11, my Samsung S9 and our HP laptop will connect to the wifi and then get kicked off after a few minutes. I only realised when I was running out of mobile data on my phone. The laptop does work when connected direct to the router with a cable.

My phone priodically says there is an authentication error and will let me reconnect for a very short period of time before it boots me off again (It says connected however how connected I'm unsure)

Any ideas?

Thanks

Ravi

Hi there @raviahluwalia, I am sorry to hear of the issues you are having with the WiFi.

It sounds like you may need to split your routers wireless frequencies, I have provided a guide on this here for you.

Let us know how you get on.
