If the LAN extender does not work after a particular distance like 2 kms, then please check the type of RJ-11 cable connected between the two LAN extenders.
It should be a normal copper cable with two wires. The wire gauge has to be 0.5 mm. The resistance of one wire should be 84 ohms per Km.
To find out resistance, first short the two wires at one end of the cable and then find the resistance at the other end. Suppose the value is X. Then first divide X by 2. Then divide the answer by the number of Kms.
For e.g. if you get 400 ohms, then 400/2=200 ohms
If the distance is 5 kms, then 200/5=40
So, the resistance of one wire is 40 ohms per km.
=================================================
Also the cable has to be of a reasonable quality.
