I have this ADSL modem/router: pirelli drg-A221g (bit.ly/107drdY)
It has one RJ-11 (ADSL Phone line) input, one output to telephone headset, and only one RJ-45 (Ethernet/lan) connection on it.
It works fine, when I am using ADSL, and I can connect several devices to it wirelessly.
Now, I want to disconnect it from RJ-11 (ADSL line), connect its RJ-45 (lan) to internet connection cable (from other company), and use it only as a router to access to internet wirelessly. I want to connect my internet cable (coming from TV-cable-modem-box) to this router and have wireless internet in my laptops and mobiles.
But it does not work!
I connect internet cable from tv-cable-modem-box to my laptop and it works ok.
Then I tried connecting this cable to the only RJ-45 port on the router.
All devices successfully connect to the router, but there is no internet!
After doing several restarts in the router, laptop and tv-cable-modem-box, (only restarts, no configuration or settings), I could get internet on my laptop. But still, my other devices are connected to the router, with no internet.
Can someone help please?
