DHCP not working

[Denny]

I have two computers connected to Comcast Cable through a Linkysys router
(wired). One of the computers has not been able to connected using DHCP and
I have had to set up the IP address etc. to connect. It would not obtain
and address. Today my modem turned off and then came back on and now I am
unable to connect using DHCP on my main computer, which before the modem
went off was running fine. If I connect directly to the computer from
modem it states the ip address is obtained (not exact words) using DHCP.
Does anyone have any ideas. Is this a Comcast issue?

Hi.

It does not seems to be Comcast problem,

It seems that few Network relates settings are not set correctly on your
computers.

Why would this be working correctly for the past few years and then all of a
sudden today after the modem turned off DHCP won't work on this computer?
Any ideas. I will try the site mentioned to see if I can work through this.
Thanks!

I upgraded the firmware on my Linkysys router and now all seems to be well.
I am able to connect using DHCP on both of the computers now.
On a side note does anyone notice the file "lucom~1.exe" being loaded on
startup. I am wondering what this goes with. It loads and then disappears
from the running programs.

Did a search on Google and discovered the "lucoms~1.exe" is a prefetch file
that is loaded when you have LiveUpdate set to Automatic. Things are looking
up : )
