hi. guys from the last 2 to 3 days whenever i switch on my modem then it does boot up normally but immediately after booting the indicator for internet starts glowing continuously.. (which should be switched off ) and when i dial my connection it says.. error 676 your phone line is busy... this happens almost 4 out of 5 times and whenever it happens i hav to reboot the modem and try my luck again.. its very annoying.. any solutions ?? also im using GDMT ... tho the problum persists on all protocols.. ive tried all of em.
