Most people with old routers don't even realise the router is randomly bugging out and slowing down your web page load speeds.

Fun fact: Old routers generally don't support WiFi power saving features. That means your phone battery will drain waaay faster than it could if you had a new router. Having WiFi switched on with a phone connected to a new router will in fact generally increase battery life because it can use the cell radio less often.

The general point is "local direct communication is hard and unreliable". Your phone falls back to 3G - connection broken. You're on "HouseWifi" and the other device is on "HouseWifi_5Ghz" - connection broken. You have a router with a guest mode and stops guests accessing the local LAN - guest can't print or chromecast or whatever.

Please don't bundle Android and the rest of Google software. They are two different teams with two different philosophies, and one team doesn't like to have it's reputation hit by the other teams faults.

Remember Android wasn't originally designed by Google, and many of it's security design decisions and culture were inherited.
