Never had this problem before. The day before yesterday, I was suddenly unable to connect to the internet for any length of time. I usually either get an error 619 ("A connection to the remote computer could not be established so the port used for this connection was closed") or an error 721 ("Remote computer did not respond).
I use a BT Voyager ADSL USB modem and the connection is brief when I try to connect, about 15 or so seconds, then the modem goes into 'training' and the connection drops. It then connects for 15 or so seconds then drops again, and just seems to either carry on like this or just doesn't connect at all. I know this is the case by looking at the two arrows in the system tray changing colour and by the 'link' light on the modem itself being steady then flashing when the connection drops.
I've done tests and it says the broadband connection to the flat is fine, it's just not getting to the computer properly.
We've gone throught the rigmarole (spelling? - I'm at work and no iespell!) with the BT helpline and they seem to think it's a 'port problem' and advised us to have it looked at by a computer engineer.
My wife's pal who's a networking engineer thinks it may be either a faulty ethernet port on the computer (the modem is connected via USB so am I right in thinking that's not the problem?), a network connection which has been disabled in Windows or a problems with the DNS settings on the router (not sure what that means). Unfortunately, she's on a course all week and unable to come round for a look so I was wondering if anyone could offer some advice meantime which may help get me up and running again. I'm thinking that maybe I should get a new router, but that's just a stab in the dark. Thanks. Glynn.
