Often there are only ever 3 concurrent devices online in any home.
Browser can preload links at the client level, but this often results in a slowdown to the user and increased CPU load.
I believe home routers should be more advanced, so when pages are loaded the router pre-loads links related. So that when for instance a Google search result page loads the router begins preloading all of the resulting pages, or when a user is on a website the router begins to pre-load other pages on the website.
If done right, the user should get a faster more stream-lined experience.
