Wi-Fi interference (nothing to do with electrical interference) can cause:-
Slow speed,
intermittent dropouts,
breaks in the signal,
no signal at all,
or no internet access.
This can affect one or more devices. This can also lead to a permanent reduction in the speed of one or more devices. No ISP can be responsible for your local environment; this is mainly a byproduct of the popularity of Wi-Fi. However, other factors should be investigated first. When this happens, what are the lights showing on the front of the router? Do you have any wired connections & if so, how do they perform? Generally speaking, the 2.4GHz band suffers far more from Wi-Fi interference than the much faster 5GHz band. However, the 2.4GHz band has a longer range than the 5GHz band and can penetrate walls better. This may very well change depending 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 my sending out a guide to help you get important diagnostic information for me. I will then analyse these results for you and recommend changes to your router configuration, if required.
I only send this out to people who request it.
