IP Address Renewal Failure

[Guest]

Working on trying to restore network connection on friends computer. She has
satellite internet. Has Modem and Router. Modem and router seem to work
because am able to connect with laptop and wireless NIC. Main computer has
new and old NIC (both wired). Both NIC's on problem computer work when we
brought her computer to my house. (I have high speed cable with modem and
router). Still unable to get connection with her system. Tried IP release, IP
Renew, disabled firewall, tried "repair connection". Get "unable to renew IP
address" error. Checked and all protocalls and settings are the same as I
have on my system. Checked cables by removing router and connecting directly
into modem with known good cable. Still no results. Have unplugged power to
modem, router and computer for 5 minutes and powered up each in following
order (modem, router, computer).

Any ideas as to what to try next???

You may want to re-configure the NIC settings such as speed and duplex. This search result may help,

Ipconfig Can ping IP but not hostname after installed/upgraded software Can receive IP packets but not send them Can't obtain/renew IP addresses from the DHCP server ...

Believe have determined problem. Tried new nic and used laptop that worked on
that network before. Both function perfectly on another similar network but
not on problem network. Has to be Modem.
