I guess my ISP uses some subpar hardware because the connection keeps dropping at peak hours. I want to implement a failover system without having to buy some expensive router which I would not be able to justify with my normal usage.
Wanted to know some other ways how people do it .
A Raspberry Pi with two network interfaces (one can be a USB-to-Ethernet or USB-to-WiFi adapter) can be set up as a failover router. Just write scripts to check the internet connectivity regularly and switch between connections as needed.
