Wifi speeds since mid December 2022 have gotten much worse with zero sign of improvement

[Cyberjynx]

Since mid-December last year, my wifi speeds have gone from around 24ish Mbps to around 3 Mbps at most and have never recovered. I've tried most of the suggestions such as resetting the router, turning it off for 10+ minutes, repositioning the router, etc, but nothing worked. And this applies to all wifi devices within the home such as phones, tablets and smart TVs. I even had some friends who came around to visit and log in via their phones and test the speeds and it was the same result. Furthermore, there's nothing wrong with the signal. Max strength of five bars and never dips below that. Any idea what could be wrong? 

Thanks in advance.

Hi Cyberjynx

Do you still need help with this?

Thanks

Mate, do you, or anyone you know have a laptop and a spare ethernet cable (RJ45 to RJ45).  You might have one of the yellow cables from an old broadband setup lying around.  I would try running the laptop direct from the router (one of the LAN ports) and then do an Ookla speed test to see what that tells you.  This would at least exclude the possibility of the Wifi part of the setup being at fault if you got a slow speed on the network cable too.

Hello Debbie

Thanks for the quick response and yes, I have turned the router off multiple times and one of those times I did for a little over one hour.

Hi Cyberjynx

I'm sorry to hear this.

Have you also powered down the router for a full 30 minutes and then run a speed test?

Thanks
