I have lost track of how many people say their internet is crap - when it's actually because they are using wifi and a poorly optimised setup to boot, eg router at other end of house to where they are. Or they use "mesh" devices which are good for coverage but not great for throughput.

How do you propose this is improved?

It's all well and good saying the setup is poorly optimised but the average consumer will likely never understand what it means.

The onus shouldn't be on the end-user to understand the systems but on the internet companies to advise how to get the most out of their connections or to explore ways to improve them.

However, advertising does muddle the situation regarding Wi-Fi. I believe it's BT who advertise that their router's 'fast broadband' etc can reach all areas of the home and promise to provide extenders for free if unsatisfactory. Certainly sounds contradictory to the "optimal setup". I'm sure other companies do similar, implying that getting a signal automatically means a good internet connection.

I don't think it helps either that ethernet ports are no longer included on a lot of products, and the ability to use them is prohibited by cost of adapters and such. My Surface didn't come with an ethernet adapter and if I wanted a wired connection, I'd have to pay £255 for the privilege.
