Problems with new Dimension 8300 and Conexant Modem

No, this has been happening since I first got the system. I have no viruses or spyware.

I've also run the Dell Modem Test utilities, and they all indicate that the modem is working correctly.

As soon as I connect with the modem, however, the mouse starts locking up - sometimes it comes back, but eventually, the entire system locks up, and doesn't even respond to a Ctrl-Alt-Del.

ajkerr,

Thanks for using the Dell Community Forum.

Is this something that just started happening?  What changes have been made to the system?  Have you checked for a virus or spywear? 

ajkerr,

Who is your ISP and what sites are you going to?  Does it happen if you were to stay at the same site or just when you download something.  Try finding any sort of pattern.

Hi there,

My primary means of accessing the internet is via a cable modem. However, I use dialup as a backup.

My ISP uses a plain vanilla PPP connection, and works flawlessly on my older Dell box, running Windows 2000, using identical settings.

I also have a dialup connection to a work VPN, which also fails on this machine.

The only thing that succeeds is the intial connection and user/password handshake. Beyond that, *any* network access, including attempting to ping DNS servers, access the web, etc. causes the computer to slow down. Network access always fails, and no host lookups succeed. As I said before, sometimes Windows XP stops responding altogether.

I really suspect a hardware problem with the Conexant modem - any suggestions?

An update on my situation... I disabled the "QoS Packet Scheduler" in the dialup connection properties (I'm running XP Pro), and lo and behold, everything is now working correctly.

I guess it was an XP problem, not a modem problem, but it's strange that I couldn't find any references to this fix on the internet.

Hope this is helpful to others.
