Hi;
Wireshark is a great program, but I would not try to use it to troubleshoot if you don't already know your way around with it. It's complex and will probably raise more questions than it answers. Get up to speed with it on a computer that is functioning.

Start with the basics, and try "divide and conquer" if possible. What do you get from ipconfig /all? Are you getting a DHCP lease? Have you verified the NIC driver is fully up-to date? (I assume it is wired). Is the switch and the NIC both set to auto? Do you have another computer you can plug into the end of the cable and compare?

Hi Raargh.. I did ipconfig and i'm not sure what how to tell if i'm getting a DHCP lease. I half the instances of DHCP say enabled and half say disabled... but dont see anything about DHCP Lease...

Also, I tried maxxing out my DHCP range as suggested here. Dunno if that comment was for me but it didn't help its still seems to be happening.

thanks guys

Can you please do an ipconfig /all and post it here?

Sorry I don't have a specific suggestion to fix the problem, but gathering data is always a good first step.

Hey Raargh.

I know you're trying to be helpful and actually are being, but I wouldn't advise posting such personal info as internal ip addresses and especially mac info online for public to see.

heh - I edited the MACs and IPs that could reveal any personal info. . I'm old and paranoid.

@drago - ditto for when you post - either blank out the MACs or alter them.

Thanks!
