Here is my response for some of the above querries.
It is still a sad state of affair that there is no unlimited 256 kbps plan for mumbai. I use it, although it has closed last month. My account page still shows that I am using 256kbps unlimited. It gives around 50 GB download per month. I think within 6 months 512 kbps ulmited will be available, which will enable people to watch live streaming movies at decent quality.
ADSL routers are notoriously bad with power fluctuation. This is the biggest reson for random disconnection other is that telephone phone line is not properly set-up. If your telephone gives too much hissing sound, that get for telephone line fixed with local lines-mam. Best remedy against power fluctuation is to connect Router with UPS. That should reduce some disconnections. It has helped me. Sometimes when i do get disconnected i turned off my router for 2 minutes then turn it on. Sometime without a 2 minute break, the connection won't get established. There is no need to restart your PC.
For people with port forwarding issues, it depends upon the router you are using, using bridge connection should solve this prblem on 90% of the case. Dlink 502-T is very simple to configure as it gives lots of options.
