iam suddenly getting very slow speeds 24 kbps bandwidth such that even the bsnl speed tester takes 15min to show. also i tried to connect lot of times and failed(from 6pm i tried and got connection only now 9pm). bridge mode utr300r2u modem 500c plan. will changing to pppoe mode solve the problem. or is it that my modem is damaged(3 months old)?
will changing back to bsnl dns solve it? if so what are bsnl dns servers?
please help???

OMG you are getting really slow speeds ............ which DNS servers are you using use open DNS servers i.e.
Primary DNS: 208.67.220.220
Sec. DNS: 208.67.222.222

see this solves your problem also check your line attenuation and SNR values and check whether there is some disturbance in your line(dial tone) or not

it is nothing to do with how old your modem is and there will be no effect whether you use bridge mode or pppoe mode

DNS servers wont be able to increase your download speed but it can increase your browsing speed

there is no disturbance in dialtone.
what are the bsnl dns servers?
still getting low speeds 60kbps?
are anyone else experiencing it in chennai?

whitestar_999 · 06-08-08, 11:36 AM

it maybe due to some problem on bsnl's part if everythng else is alright on your end.try to ask some other users in your area if they are having same problem or contact local exchange.they should be able to tell you if its a common problem or not.
