Hello! I need a big help with the router. The router has 8 ports. I have
three computers and I am trying to connect all of them into the same routers.
Two of the computers really connected to the router and everything was fine,
but one of the computers won't connect to it. I unplugged the cable modem and
router and plugged back in. Its the same problem. I put the modem into the
uplink from the router and it used to be work that way. I don't know whats
the problem. I looked up in command and typed in as "ipconfig/all" for the
one didnt work for internet. I didn't see dhcp or dhp server. they were gone.
So can you help me with this problem? I would be glad if you can solve this
problem. Thanks

Your problem would probably best be solved with the Network Setup Wizard. Run
the wizard on the problem computer, and select
This computer connects to the Internet through another computer on my network or
through a residential gateway.

If two computers are fine, and just one is a problem, don't waste time with the
modem and router, work on the problem computer. But try swapping router ports,
and cables, between the problem computer and the others.

IMHO I would't run any Wizards. These are mainly intended for use with
Internet Connection Sharing, (ICS) not for routers, and may mess-up the
settings on the computers that ARE working, leaving you with none online!

You first port of call should be to run

ipconfig /all

from a commandprompt, to find out what the settings on the computers are.
This should highlight any anomalies between the working and non-working
machines.

All should have the same gateway and DNS settings. Each computer's IP
address should be different, BUT they should all be in the same range (which
generally means only the last of the four sections being different)

Then try pinging the router's IP address from each computer, for example:

ping 192.168.1.1 (Obviously, substitute the actual router IP)

This should tell you if the machine can 'see' the router over the internal
cabling.

The exact situation will depend on whether the computers each have a fixed
IP adresses, or whether IPs are being allocated by the router's DHCP server.

Either way, the Default Gateway and DNS Server should normally be the
router's IP address.

If all this seems correct and it still doesn't work, then I'd suspect a
problem with the firewall (or possibly the antivirus if it's Norton) on the
faulty computer.
