I have a unique problem of my router acting bad very very frequently. I used to grumble, nag family members, try to fix it, fight with bsnl. Nothing seems to have worked. Now router is said to be spoiled. So I thought of another solution. Why not use mobile for internet. Kids always do that. So I bought an internet plan. This is essential, otherwise your mobile currency will be drained in less than a day. Activate your mobile data . In my samsung phone it is pull down the status bar. There is an option for mobile data. Click on that You should see an indicator which might say either 3G (if you have 3G internet plan) or H with two arrows in it. If it is not shown, internet is not active. Check if you have dual sim and is the mobile data using the correct sim. Mine had that problem. If you want to connect only one device, say a laptop, the better option is connect to internet using usb Connect your phone to laptop using usb cable Start usb tethering using settings....
