I have a house in a village that is a double apartment, and I have a wifi on the floor although it doesn't spread the signal to the upper part, what is the device I should buy to extend the signal, the connection is DSL and the modem is technicolor.
Hi
There're several ways to accomplish what you need:
1- The technicolor DSL modem/router as the most of them come without antennas, so you can replace it with another router with antennas that has more signal power but you should know how to change the settings in the router to meet the old router settings.
2- You can add a wireless wifi repeater that re-transmits the same wifi signal (Same SSID and password) but the cheap repeaters in available in Lebanon are not so reliable.(It also needs to be configured).
3- You can add another high power wifi router (i use this way in my home) and connect the two routers with Ethernet cable, the second router works as standalone router and gets its internet from the DSL router and has its own SSID and password.

Thanks, that's quite valuable information, I think the 3rd option as you stated is the best one to go with, although I'm not sure about:

1- If the subscription will be independent for each modem or just the SSID & pwd.
2- the "villa" is 3 apartments, I can just get 2 modems and 2 cables and crossover them together over the balcony, with 3 modems in 3 rooms in 3 apartments with cables over the balcony. I'll have to measure distance and get the cables and the modems, I have a worry though since the cables will be outside if they'll be affected by rain or extreme sun heat.

That's all, thanks again.
Hi again
First of all what you need to add is a wifi router not a modem (you don't need a modem)
All the added routers will get internet access from the DSL moden so one subscription for all the added routers.
Just buy a good quality Ethernet cable and it will be heat and water proof.
You should edit some settings in the new router to make it work (it is not so hard):
1- Obtain the IP address of your modem it should be 192.168.?.?
2- set the new router IP to be at the same subnet of the modem (if the modem IP is 192.168.1.1 the new router should be for example 192.168.1.2 and the third one should be 192.168.1.3)
3- Disable the DHCP in the new routers.
4- connect the cables to LAN port not the WAN (not crossover cable)

Hi,

Thanks for the straight to the point information, I have a Technicolor tg582n stock modem that comes with every subscriber.

I will buy 2 wifi routers from the same brand "technicolor" as I've heard it would be better to avoid complications, the ip address in which I access the interface of the modem is 192.168.1.254, I guess with that I'll have to set the 2nd router to 192.168.1.255, 3rd 192.168.1.256. then disable DHCP for both.

Here's an issue though, in the Technicolor documentation it says the last ip in the range is 192.168.1.254:


In the router properties on my PC, it shows the ip address of:192.168.1.253, despite accessing it from 192.168.1.254? What should I set the two router's ip in this case?

I also found this:


then I'll just connect the Ethernet cables from the 2nd router to the 1st modem, and the 3rd router to the 2nd router -or- to the 1st modem?

.
Hi
You cannot enter an IP address more than 254, anyway to set the first router use 192.168.1.1 and for the second use 192.168.1.2, they should all have the same subnet 192.168.1.?.

I don't think it will give you issue if you use another router brand, it is a global protocol and if you set things right it should work without any problems.
You can connect in both ways from Modem 1 to router 2 and from router 2 to router 3 or from Modem 1 to both routers, but the first way makes the second router have a delay, i'll prefer the second way.
Just use the appropriate device such as this.
Note: You can set it up in one step after plugging it, it will have the same name as your original access point, and basically the coverage will be extended with the same name.
I don't recommend the wife repeater, i used the wifi repeater and it was very poorly unreliable, it freezes if several devices connected to it and it slows down the speed. Unless you can find a good reliable one connecting a second router is the best way.
Wires are always better if it isn't a hassle, i second nuclear vision a repeater is better option and what's even better is to create a wifi bridge between the two most routers support wifi bridge, i use that at work to bridge 10 access points, every two together works like a charm with 50 to 150 users roaming in the building.

You should have invested in a better one.
