from 50 KB to 400 KB my internet service provider has something wrong on his server?

[Ram]

I use TP-LINK wireless modem and from it i connect to pc via lan cable.my plan is 512 kbps(bandwidth) and i get download speed of 50-60 KBPS.one day suddenly my speed went to 400-500 KBPS.actually i was downloading a game of 5 GB and it almost reached 70%in 30 min.I think it happened due to some error in local service provider in our locality.although is there any possibility to hack and get those high speed constantly?????please any hacking experts answer me.
although this doesn't seem legit please sort a way so that i may use the trick rarely.Thanks in advance

If you are using BSNL broadband, then there is CAP on upper GB that you can consume depending on your plan. For ex: IF You are using Broadband 650 Rs plan then upto 3GB speed will be 512 Kbps, after it exceeds 3GB, your speed will become 256 Kbps as it is unlimited plan. You may have reached your upper GB limit currently.

From the way I see it, ur service provider just throttled your speed to make sure you go above the download lmit this month and then charge you more. there is never anything wrong with the nservice provider as he knows exactly what when and how much you browse.
So hacking is not a possibility. better is to move to a better service provider who can give atleast 500kbps as broad band speeds.
50kbps is not even a broad band speed, but dial-up speed which was like 10 yrs back. So in reality you are not even getting what you are paying for in the first place as a broadband subscriber. On BSNL I pay 900Rs and get 1Mbps minimum speed mostly and at nights more than 2mbps. so change ur service.

Seems like you don't know how it works. At the beginning of every month, you get a reserved bandwidth until which your speed will be high (in your case, 400Kbps) But as your bandwidth quota is finished, you start to get low speeds.
