2.4Ghz speed is only 20Mps 5Ghz is 450Mps

[jigsaw004]

Getting very low speeds on 2.4Ghz whereas 5Ghz is running at expected speed of 450Mps

Also 2.4 Ghz connection keeps disappearing and need to reboot route.r Any ideas?

HI @jigsaw004 

Perhaps your WiFi 6E card is only configured to use the 2.4GHz band, not the 5GHz. You can check this on your PC/Laptop by going to (assuming Windows 11):-

Settings > Network & Internet > WiFi > Hardware Properties > More Adapter Options > Edit

Then in the resultant box, click the Configure button, followed by the Advanced tab. What properties are listed here depends on your WiFi card's driver. Look in there for something like "802.11n/ac/ax" & see what it is set to, it might be disabled. If in doubt, please PM me a screenshot of the full list of properties available.

The problem seems to affect only the PC/laptop, other devices are fine. It cannot detect the 5GHz band despite being a WiFi 6E card. Is it running the latest drivers for it?

Do you have a USB WiFi 5 or 6 one that you can borrow?

I am currently analysing the customer's diagnostic information.

Hi @jigsaw004 

Thanks for that zip file, I will get on the case a bit later this afternoon.

Hi @jigsaw004 

Do not worry about interpreting the results; I will do that for you. I will send a PM to 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.

Hello Keith

Thank you for offering your help.

I would love to see the guide, can you send it please.

Much appreciated

Hi @jigsaw004 

@Debbie-TalkTalk has asked me to help you. One other point is that the 5GHz band should be faster as the network adapters in your devices are designed to work faster in this band.

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 will try to help you optimise your Wi-Fi connection. The next stage involves sending out a guide 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

I was sent a WiFi Hub the same as I already had.

Fast 5464

[Debbie-TalkTalk]

Hi @jigsaw004 

Did you receive an eero or WIFI hub?

[jigsaw004]

Hi

I have installed the replacement router but it has made no difference

5Ghz is giving me speeds of 450Mps  whereas 2.4Ghz is only giving me speeds of about 35-40Mps if I am lucky.

These are speeds when next to the router.

I have moved router to different positions etc but has made no difference.

What can I try now?

Thank you

[Debbie-TalkTalk]

Hi @jigsaw004 

No problem 🙂

Debbie

[Debbie-TalkTalk]

Hi @jigsaw004 

Thank you. I've ordered the replacement router, please allow 24-48hrs for this to arrive.

If you receive an email to advise that this is chargeable then please ignore this, I've sent the router free of charge.

Thanks
