I have got my Airtel connection in Bangalore yesterday. As there is some offer going on, I have received wi-fi modem for free. The model is Binatone DT 850W. After the technical person set up the connection, the wifi works fine without any issue. But it started troubling after i connected to my desktop. I have connected my desktop using cable and laptop using WIFI. In desktop i could use internet but it in the laptop the internet is not woking. But if i remove the cable from the Desktop then the internet starts working in laptop. Also the Wifi router refreshes automatically. Some times the ADSL led itself is not glowing. Can you please help me to resolve the issue.
