New router for extended wi-fi range

[Sparkofd]

Hi, I will be upgrading my connection to fiber in these days (yeah yeah, third world..)
The modem I have now and the one i'm getting with the fiber are not powerful at all, so I'll be buying a router to extend the wi-fi range
My house is like 12m x 30m (not sure about the 30m), my room is in the back of the house, behind the courtyard, we use 3 or 4 smartphones, we want to use a smart TV for netflix (we can't do it with our current modem), and a notebook that's located maybe 15-20 meters and 4 walls away (I do have a little signal right now, although it's farther than the TV).
Will this router be enough to cover all the house?

I can pay up to 120-130 dls for something like this

but only if I will really really need it.
Or maybe I can pair the asus router with a range extender, and plug the TV via ethernet.
In addition, my new speed will be 30/4 mbits, so I think there's no need for fast routers, I only want a powerful signal

Although there are some small difference most routers including the crappy ones provided by most ISP put out close to the maximum allowed radio power. This mean more or less they will all have about the same coverage. Mostly it would be a battery powered router or a mobile hotspot that does not put out a lot of power.

You house makes much more differnce than the router. Houses that wifi passes though easily you might get the distance you want. Other for example that are made from poured concrete may not even get out of the room with the router. Still the more common problem now days it not the coverage it is the "too much" coverage your neighbors router has so it interference with your reducing your usable coverage distance.

So first I would see how bad it is. After that I would look at powerline network devices since these are dependent on the electrical wires and not what the walls are made of. In general they work better in houses where you can not get good wireless coverage. There are the rare houses they do not work in.

A wireless repeater should be your last option. You must consider this only when you feel that any signal is better than nothing at all. You now have 2 radio signals you can have issues with as well as the interference the device itself causes to the main router reducing your data rates.

Thanks for your reply.
About the new modem, even my internet provider itself told me the new modem won't have much range.
I didn't know about powerline devices, I will look into it when I get my fiber line, but I have a few questions about it:

Is it as easy as it sounds? Let's say my house is ideal and I don't find any problem with the wiring: can I just plug one adapter in my room and the other one in the front of the house next to the TV and netflix all day?

Is it possible to plug the first adapter to the modem while connecting the second one to a router, thereby ensuring my PC would have ethernet while the rest of the house is covered via wi-fi?

It is pretty simple most the time. This is also the bad part because there are no settings so their either work or they do not. Only a very small number of houses have issues. The newer units that are based on the latest standard av2 use even the grounding wire so they can get around some of the nasty issues some people had. If you watch you might get the av1200 models from tplink on sale for less than even the old av200 ones.

You have to be careful about your terminology when you say "modem". It will work no matter if the modem is a modem/router or just a modem but running it powerline to connect the modem to its router can cause issues sometimes. Now if you want to connect a second router to the first via powerline it has the same restrictions/problems doing it with a ethernet cable. You want to run the second device as a AP rather than a router. Some router have a AP function but it is mostly a cabling thing. You will find 1000s of hits if you search how do I use my router as a AP.

I understand, my last question would be this: Is it a problem plugging the device with an adapter? I live in Uruguay and we have other plugs here
Besides that, could you recommend me a powerline adapter? I was looking at some netgear and tp-link but any opinion is welcome

The plug questions is one of those things I have always wondered also but most people on these forums are from USA or EU.

My guess is that you can use a model based for EU installations. They both run on 230volt 50hz power. Pretty much the only difference is the physical plug which there are adapters for. The adapters are just simple metal contact in plastic so I can't think that would make much difference.

Now if you tried to run USA ones that run on 120volts at 60hz the converters for those are electrical devices so I suspect it would block powerline.

Since these post get lost very quickly on this forum maybe make a post on the networking forum asking about powerline for your country in the title maybe someone will see it and know that has actually done it.
