Poor speed to devices

[Freund]

I am having trouble with low speed to my Apple devices. I have run a Talktalk speed test, which shows good speed to the router, but poor speed to both my iMac (52Mbps) and my iPhone 13 (9Mbps). I am on Fibre 65. The router is Sagemcon TalkTalk Wi-Fi Hub FAST 5364.

The problem is particularly noticeable with my iPhone 13 (my old iPhone 8 has no connection issues or dropouts), which shows it's connected to WIFI, but there is no internet connection once the phone is woken from sleep. I have to toggle airplane mode on and off to get it to come on again. 

Also, the last couple of days the phone reception has been really poor when connected to WIFI, not sure if that's related.

Any help would be most welcome. I have seen similar issues mentioned on this forum,  @KeithFrench

Hi @Freund 

How are you getting on?

Hi @Freund @Debbie-TalkTalk 

A summary so far of what I have found:-

Apart from the different names currently, your network looks fine. I would suggest that you rename one or both WiFi bands to whatever you want.

Saying that your network is fine though is only true for the current location of your Mac, where your phones drop out, it might be a different story. If the Mac is a laptop, please could you move it to bad reception areas & get me another set of screenshots?

Hi @Freund 

Do not worry about interpreting the results, I will do that for you. I will send a PM to you that contains a link for a guide of mine on Wi-Fi interference. It is quite long (about 30 pages), but you will probably only need to look at three or four pages in total. Initially look at the section called "Are you suffering from interference – prove it first". This is the first link in the table of contents. This section includes full details of free Wi-Fi analysers that I recommend for Windows, Windows phone, Android and Apple operating systems. However, I have no way of testing the Apple product. Select the analyser of your choice & my guide explains how to use it.

If you are using Wi-Fi Scanner, then please attach the zip file to this thread. As soon as I have downloaded it, I will remove the attachment from your post, to preserve your privacy.

With all other analysers, please follow my instructions below.

Collect the screenshots that I require and include them in your reply.

Please post the screenshots to me in a PM (to protect your privacy), which I have requested in my guide. No photos please as they can be difficult to read, because the text can get out of focus when zoomed in. Please ensure that the analyser window is maximised (if Windows) before taking the screenshots & upload them via the "Insert Photos" button (in a mobile browser it's the picture icon) on the post editor's toolbar with the Size parameter set to Large.

Yes, please, any guidance on optimising my settings would be very much appreciated.

Hi @Freund 

Slow speed, intermittent dropouts, breaks in the signal or no signal on some or all devices or no internet access 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 byproduct of the popularity of Wi-Fi.

Generally speaking, the 2.4GHz band suffers a lot more from interference than the much faster 5GHz band, but the 2.4GHz one can sometimes have a better range, but this all depends on your local area.

In other words, I try to help you optimise your Wi-Fi connection. The next stage involves sending out a guide to you to help you get me some important diagnostic results so that 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.

Hi @Freund 

Thanks for your reply.

Please can you add your name and TalkTalk landline number to your Community Profile, we can then take a look at this for you.

Thanks

Yes, I turned off the router over night, but the issue is still there.

Hi @Freund 

I'm sorry to hear this.

Have you tried powering down the router for a full 30 minutes?
