Why does Vista lose internet connectivity every 20-30 mins. I have to use the following command to reset it but this only lasts for about 20 mins before i have to repeat it again:

ipconfig /flushdns

I have not lost my internet connection, using this beta.

try this cmd after ipconfig /registerdns

/registerdns Refreshes all DHCP leases and re-registers DNS names

Are you using a 3rd partty firewall, and if you are using a 3rd party firewall

does it allow for the Ipv6 protocall, because Vista uses that instead of Ipv4

Register DNS only applies if your machine is in a domain. You can't register your machine to a public DNS server. Also, Vista uses IPv6 and v4. You can't use v6 exclusively at this time.

I suppose the only workaround is to:

ipconfig /release
ipconfig /renew

...everytime you drop the connection.

I have 2 pcs sharing an internet connection via a Linksys router.

My pc dual boots xpro and vista.

The 2nd pc runs xpro.

Whenever I am in Vista I lose connection on the 2nd pc and need to boot into xp 2x and unplug the power to reset the connection on both my dsl modem and router before I get internet connectivity back.

How do I fix this, any suggestions?
