Please help me out in following :
When I connect another router to my existing router, the internet stops working.
I have tried this on Wateen Wimax Thunderbolt device which has a built in Wifi router and provision for connecting 2 LAN cables. This device was working fine but as soon as I connected my TP LINK wifi router to this device, the internet stopped working.
For experimental purpose, I used PTCL EVO device plugged on 3.5 G router and connected my TP link router. Again there was problem. I have also used different LAN cables (to ensure that there is no fault in the cable)
I think there might be some conflict which I am unable to figure out.
(you might be wondering why I need to plug another router. Its because I want to increase the range of Wifi to Upper story of my house.)
