Friends I have posted a message on difficulty in uploading and using gmail, hotmail and bank online transaction with BSNL Dataone UTStarcom WA3002-g1 - Type II Modem. Atlast, the BSNL officials were kind enough to attend to this problem after a long time by simple change in the configuration of the modem. I am giving the details below for the use of many members who have expressed similar problem through private message to me:
Open IE browser and type the address: 192.168.1.2
Open the page by giving username and password as: admin
At the bottom of the page change the value 1500 as 1492
for : TCP MTU Option: TCP MTU(0:default) ..... bytes.
Then, click Advanced Setup -> ADSL
Set the ADSL Mode : Auto-Sync Up
Then, click Maintenance -> SysRestart
Set System Restart with: Current settings
Close the web browser.
With the above configuration, I am not having upload problem.
Those of you having problem with the above Modem can try this configuration.
