I am living in an area where no broadband service provider is providing broadband connection. So I had to take wireless connection such a reliance netConnect USB modem connection. I can tell you this is the only-only reason why I took this connection.
If you see that reliance netconnect advertisement on TV, you can see guy travelling in his car seeing the video of his new born baby!! Never try to do that in your car because you might be very well disappointed!!
Use only if you have a good signal. If you using a laptop, move around in your rooms and find where you get the best signal. Also, there are some antennas available in ebay for increasing signal strength. I have not tried it. But heard from others that it improves signal to some extent.
Connect the earphone to your USB modem and let it freely hang. This has worked for me!! Try various placements of that earphone cable and find out where you get the best signal.
Try and see whether you can use any nearby browsing center, if you have. The cost involved is more or less the same I think.
Use if for simple browsing/email purpose only. You should forget youtube :(
In night after 10pm you might some good speeds. So if you have freedom@night plan you can think about downloading some stuff.
If you know something about linux, then try to netConnect on easy to use Ubuntu Linux. How to configure netconnect for linux it is given here. I have found the total MBs downloaded per night is more in Ubuntu linux than it is in Windows!!
Finally note that this is no substitute to a wired broadband connection. This can be called as a good Dial-up connection. Also remember that we are living in India. :D We can expect good speed may be when we get 3G in India.
