Poor connectivity in part of my home

[CMJTW]

One room in my house suffers from poor connectivity, what can I do to improve it?

My router is a Sagemcom FAST 5464-2

I have replied to you on a similar topic and have asked for a copy of your guide. I am surrounded by  up to ten wifi networks and one neighbour has an external cable from what I believe is his fibre connection up to an office. I imagine that this is probably acting as a radio transmitter

I assume that you are talking about WiFi connections?

Slow speed, intermittent dropouts, breaks in the signal, 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. If you would like me to help you, please can you specify the make/model of TalkTalk router that you are using?
