Bro do you have the admin username and password for the TG784nV3? If you don't, it will be very hard to do any further stuff with that extra router, as you need the administrative login and password for that router, and not the user username and password if that make sense.

Where are you located?

In that case, it should be relatively straightforward to do. I'm not an IT guy lol, so I couldn't help you even if I wanted to. I know some basic knowledge, but that's about it. It would be better to find someone who knows what they are doing. Try kaodim.com and search 'Networking Installation and Configuration'.

Try to get an extender or powerline. They are both easy configure and not too complicated.

Bro as I say, if you want plug and play, try extender or powerline, which may come with wireless capabilities.

It would halve the thoroughtput, so higher ping times. Powerline would be better. If you're not using the IPTV or VoIP from Maxis, just change the router to something better, like Asus or the higher end TP-Link routers.
