In my home, I have 2 ISPs providing internet service – SingNet and Starhub. I won’t get into details as to why I have 2, but the fact is, I have 2.
For a long time, these 2 ISPs have remained separate. PCs and laptops connected to one can’t see the other, and vice versa. When one ISP fails, we’d have to manually go to the router and plug the LAN cable into the other one, to continue having internet service. Now, we’re (meaning the people in my household) are naturally lazy. The thought of having to walk to the routers, sort out which cable is the right one, and plugging it into the other ISP, is a headache that we dread. It was made even more apparent recently when my ISP seemed to be having some minor lag issues with an online game I’m playing, and by swapping my cable over to the other one, I confirmed that the fault lay in the ISP and not in any of my PCs or laptops.
During the troubleshooting, I had to plug, unplug, replug the cables many times, and as you can imagine, it’s tiring.
