well i c no probs with buyin a modem from outside ...
coz these guyz in my area say it will take 20 days for installation if i got the modem from them
so i got the modem from outside , it cost me 1800 bucks
but hey hang on ,
BSNL charges 1200 bucks and takes 500 for installation
so, u dont need any installation when u buy from outside coz they cant do it
if u buy outside go for d-link as it much more superior then its malaysian counterpart which BSNL offers (and gives a 1yr warranty , same as BSNL)
just a little tweak while installation will do ,
the default values of vpi and vci in d-link are 0 ,32 respectively ...
in pvc0 (ie in D-link)
go to advanced settings , under WAN settings change pvc0 to pvc3
ie in pppoE LLC only
and continue from there on
i assure u , there wont be a prob
if at all there is one u can always post back !!!!
