Poor wifi after moving to Fibre 150

Knightly2309 — Wed, 30 Jul 2025 19:31:17 GMT

Hi, looking for some guidance, moved to full fibre and Wifi Hub 3 FAST 5359, and the wifi connection is not as good as the previous FAST 5364. Are there extenders that work with Hub 3 or any settings i can change. Thanks

You could continue to use the 5364 for the time being if you still have it.

@KeithFrench Can you advise here at all, please?

Yes there is an extender to turn the WiFi Hub 3 into a mesh and settings that you can change. However, I would never advise changing any without checking the state of your WiFi network. This is where I can help a lot.

First though where roughly in your property is your Hub 3 situated? It needs to be high up and in a central position. It must not be in a cupboard, but out in the open, or near any electronics.

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 band can sometimes have a better range; however, this all depends on your local area.

In other words, I offer a free, impartial analysis of your Wi-Fi network and 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 @Knightly2309

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.

Hi Keith, Zip file attached. I have PM'ed you the details. Thank you for this, Kevin

Hi @Knightly2309

I'll try and have a look at those in a while.

I have PM'd the customer for a bit of extra information about his network. When I know more, I will summarise this in this thread.

Hi @Knightly2309

Having done a diagnosis, the most obvious thing is the lack of signal strength between the downstairs & upstairs. To rectify this, I would recommend that you purchase a Sagemcom FAST266 WiFi Booster. This will turn your Hub 3 into a Wi-Fi 6 mesh network. You can purchase them either through the Better Value team or occasionally through this forum. The last price I heard was £30 (which represents 50% off), plus just under £10 for delivery.

To contact the Better Value Team (old Legacy Dept), please call: 0345 1725157.

Opening hours:-
Monday to Friday 9AM to 7PM
Saturday 9AM to 6PM
Sunday Closed

Hi @Knightly2309

In my previous post, in order to purchase a Sagemcom FAST266 WiFi Booster, you will need to contact the Better Value Team, as I said.

Thank you Keith, all sorted. Received booster and Wifi signal is working as expected.

It is a very good product. If you need any technical support for it later, I can provide that.
