Please can anyone help,

I'm trying to set up a new PC for internet access

I have created a new connection with all my relevant ISP info in it but when I attempt to connect I instantly get the message :

775 Call was blocked

This seems to happen before the modem attempts to dial. I have reinstalled the modem and all seems ok - I can query it through the device manager.

I have just removed some free ISP software that came with the machine - could that have upset something?

Any urgent help would be much appreciated.

Thanks

Sam

Hello SamB =)

>> I have just removed some free ISP software that came with the machine - could that have upset something?

I think it can..... try a System restore and check if rolling back can correct the problem,,,,, if YES then it's surely happened due to removal of these softwares !!!!

Restore the Operating System to a Previous State in Windows XP:

Hi SheharyaarSaahil

I've performed a restore - which put the software back on and followed the procedure to sign-up to this ISP (Supanet).

This dialer connected me to the internet where I had to fill in some details and obtain a username & password.

I was then prompted to close the connection and reconnect.

However on reconnecting (I guess using windows normal dun or ras?) I again get the error 775.

On further investigation it seems this modem is subsidised by this ISP and needs to be de-optimized to work with others. However I can't get it to work correctly even for its intended ISP.

FYI PC = Tiny (UK manufacturer) who have also not supplied backup disks, including XP (but can for a further $100!)

I could ivest in a new modem - but could I have damaged XP in some way?

well to tell u abt my thinking,,, it seems like more an ISP problem than a Modem problem :-?
if the modem wud be damaged,,,, it widn't connect at all !!!!

but if u still suspect a modem problem, then before wasting money on a new modem, just lend another one from anywhere, and replace it JUST TO TRY,,,, if it works then U are right,,,, if it produces the same results then im right :)

!! Good Luck !!

Hi SheharyaarSaahil

I contacted the ISP - who had to talk me through reseting the modem. It seems that because I had attempted to set up my own connection and had deleted the connection the modem is "optomized" for nothing would work.

Apparently I can use the modem to dial other ISP's - but I first need to apply for it to be de-optomized.

Thanks
