I regularly used Micromax MMX 310G usb modem with Reliance GSM sim & Rs 99 Plan which was giving me speeds upto 276 kbps..!!
From last 10 days connection hangs after a few seconds..
But when i use same modem with same card in different laptop ( friends ) in different area it works almost perfectly..!
So i formatted my system installing new windows 7.. still problem persists..!
Also wen i use Vodafone/idea sim in same modem in my laptop it works again perfect..!? But reliance sim giving problem only in my laptop..!
Its really weired..??!! please help me..
