My nic keeps losing its IP address

My nic keeps loosing its IP address

MOBO is a Jetway J939GT4-SLI-G Nvidia chipset i will fill in with more detail later

When I try to repair the connection it locks up the WS and forces to reboot weather I try the repair button or ipconfig to get a new ip address.

If I manually configure one it locks up as well.

I reload the drivers it will work for less than 12 hrs and then get APIPA.

Reset DHCP release time to 30 days to see if it would help still no luck

I have used the drivers from Jetway which doesn’t list the exact mobo I have.

Used drivers from Nvidia and no luck with those either.

Can any one help

what's your ISP connection (DSL vs Cable) and

do you have a modem? update the firmware if so.

oops; grrr; of course you have a modem; do you have a ROUTER?

...see above ...

its a motorola modem to linksys to 24 port dumb switch.

10 other WS no other network issue.

linksys fimware was updataed a few months ago no new one avaliable.

hmm; I can't see how this would ever work with multiple systems online at the same time.
A switch does not have the required DHCP service to get a unique IP address for every attached system.

Manually configuring each system would not work either as you need the NAT service of a router as well.

linksys 4 port router has the DHCP

OK! the wiring should be

modem---router---up-to-three-systems
          |
          +------- 10 port switch ---- other systems (or maybe ALL systems)

 

[largecam357]

yes that is correct configuration

The NIC driver supersedes the MOBO, but your symptoms are typical of
a driver or router firmware issue.

you might power off (pOFF) the modem and router and disconnect the switch

wait 30 seconds
pON the modem; wait 30 secs
pON the router; wait 30 secs
recable the switch to the router​

make sure ALL systems are set for DHCP to avoid any possible duplicate IP address assignments.

Can you connect the failing system directly to the router?
login an Admin account and get a command prompt (run->cmd)
issue

• ipconfig /all
  which will document a (hopefully) operational config
  (ie you can PING www.google)
• ipconfig /release
  which will undo those settings; wait 30 seconds
• ipconfig /renew
  which should succeed
  to allow ipconfig /all to replicate the first settings

tryed all of that already the issue just happens on this jetway mobo all other pc work great

 

[DelJo63]

the MOBO has nothing to do with the network -- it's all in the NIC, its driver, your router, modem or the ISP.

Those are the choices ... game, set, match.

if i manualy config the IP address in NIC properties it will accept the default gateway and DNS but not the NIC's IP address

on any one of the systems that is stable, run->ipconfig /all >mytcp.txt

then come back with a follow-up and attach mytcp.txt
