Help setup UTSTARCOM WA3002-g1 Wireless ADSL Router

I have changed from BSNL Broadband Type-I(HUAWEI SmartAX MT800) Modem to Type-II(UTSTARCOM WA3002-g1 Wireless ADSL Router) modem with wi-fi. As there was upload problem with Type-II modem, I checked the download and upload speed with a Speedometer availble online. The download speed was between 160 and 210 Kbps and the upload speed was 0 (zero!) Kbps with Type II Modem. But withmy Type-I modem, the download speed was almost same and the upload speed was between 46 Kbps and 64 Kbps. This I found by doing several tests with both the Type-I and Type-II modems. So it is confirmed that the problem is with the Type -II modem and not with my PC. With this 0 Kbps upload speed I am not able to send emails through Hotmail and Gmail and could not transact through internet banking. As usual, my complaint to BSNL, made 5 days back, has not yielded any result except few phone calls enquiring about the fault. Hence I am approaching this forum. Can anyone help me to resolve this problem. I would be glad if i get some direction on setting and configuring the Router.
