I can clarify some things on the "grounding" using the green ground cable. So technically there are three wires for every socket the green one being assigned to ground. As the name suggests on one end the green cable should be connected to a physical ground, like a huge metal sheet/physically dug pit in the ground so that in case if a surge happens all the excess current will travel through the green wire to the ground, rather than going through the equipment.

P.S. Most electricians normally leave the ground unconnected or they just connect one end of it (to the socket) and leave the other end hanging (not connected to ground), so check this if you can cause I suffered from this :p.

Thank you for the reply @achaudhary997 Okay, I'm going ahead and ordering US one because it's out of stock India-wide.

You should definitely get a surge protector if your ISP provides internet via. Ethernet (Btw, Who's your ISP)?

1. Could you help me with the CLI setup or share some resources to achieve such custom Failover/FallBack/LoadBalancing?
My ISP is excitel.
1. Yup would be happy to help. The best way is to first get familiar with the command line utility (shouldn't be tough if have used Linux environments before). The best source to learn would be the ubiquity forums.

Hi @achaudhary997 Thanks for the reply. Well, Yeah you are right about the grounding. The thing I'm asking though is that is it okay if I connect this UBNT Ethernet Protector's Ground Cable with the home's ground cable or do I need to make a totally specific ground cable and make it individual (not shared with home's). This is what I want to know (also from @Sushubh ).

Well, I've a very simple test to check the grounding. My keyboard is Metal (Mechanical Keyboard with Metal Body).

So if I get the electric current feeling while my hands/feet are wet, it means grounding is not done :p

P.S.: That much current is too much less to give you any sort of shock or damage as it's powered from USB of PC.

Coming to point, I'll be having EdgeRouter-X soon. What kind of settings (custom CLI/Config) have you done with your ER-X so far?

Thanks.

You won't need a separate ground for the surge protector AFAIK, the normal home ground should suffice.
The switching to another network after a particular number of failures can be achieved can be done by setting the count parameter in the edge router.

Source: EdgeRouter - WAN Load-Balancing (Read point 3 of Load Balancing Configuration Options)

As of now, I am not doing much just some QoS for VOIP applications like Skype, Whatsapp, and stuff. I do use OpenVPN on the edge router to connect everything in my home through PIA Vpn (when required).
