Hi. We have recently upgraded to new talk talk fibre broadband and this included a new router. All devices connected fine.  Recently our windows 10 pc (refurbished) has Started saying some settings have changed and need “network security key” to connect to talk talk. I have followed some of your suggestions from this site but no luck. I’m a bit non expert at this stuff!  PC is now not useable as can’t connect to WiFi. Please help.  Thanks.

If it is connected via a wireless connection, rather than a wired one (Ethernet) then this can only refer to the WiFi password. Are you sure that you are using the correct wireless password?

 

If not it could be getting corrupted die to WiFi interference. Slow speed, intermittent dropouts, breaks in the signal, or no signal on some or all devices, 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 by-product of the popularity of Wi-Fi.

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

To enable me to help you, please can you specify the make/model of TalkTalk router that you are using?
