Unable to use ethernet and WI-FI simultaneously

[Chirag]

I have been using Dlink 2750U for some time now. I was using usb wireless card on PC to connect to modem/router but it couldn't connect properly over long distance so I started using internet through ethernet on my PC. Now, the problem is when I am using internet on my PC (ethernet) wifi stops working on all other devices. On laptops, it connects and disconnects, connects and disconencts... If it connects websites don't open. I have to remove the LAN cable in order to use the WIFI. Any solution?

What is u r ISP connection..? check if it is MAC specific..?

BSNL. How do I check that?

I don't think BSNL would restrict to MAC.. check u r Router settings..? try checking with other devices like mobile..

Router settings seem fine. Wifi just stops working on laptops, mobile and other devices when LAN is connected.
