How to assign IP addresses to computer on home network?

robert_harper_2000

I'm trying to connect my PCs to my router which in turn is connected to a media network storage thingy.

Everything seemed fine except one pc cannot get onto the internet. I have tried connecting a ethernet cable to it and it still won't connect. It did work at one point so I'm thinking it has the same IP address and won't I turned on another pc it must have stopped that one working.

I know you can assign a new ip address to each computer through properties somehow but will I need to tell my router what is going on?

Cheers, Rob

do an ipconfig from the command (cmd) prompt to check to see if it has a local ip address.

if it does, check the connection settings in IE

What operating system?

On a working machine...

If you start a command prompt (Start-Run and type cmd in WindowsXP or Type cmd in the search of Windows Vista/7and click on cmd.exe).
On the command prompt window type ipconfig and press enter.

What does the machine report?

Repeat for the machine that can't access internet.

ip address

PC ips
168.192.0.5
168.192.0.4
168.192.0.7 - Not working
168.192.0.2

Just the one not working but it has a different ip?

That's the problem!
They should NOT have the same address...
You router should have "DHCP" turned on
Each machine should have the IP addersses blank and the option to "use DHCP" or "Automatically assign IP address" ticked.
On each machine go to CMD and in the window type:
"ipconfig /release"
and
"ipconfig / renew"
Hopefully the 2 machines will have different addresses so they can both see the internet.

any firewall installed?

any infections

any proxy server set in IE connections?

Are they all allocated by DHCP or is the non working a static address?

If static is the gateway IP address the same for the non working PC as the others? Is the DNS server address the same as the others? (ipconfig /all should give this information)

How is the "Network Storage thingy" set up? Is it DHCP or static address?

Apple Tv 192.168.0.1

Four PCs
All have same details
Default Gateway 192.168.0.1
DHCP Server 192.168.0.1
DHCP Enabled Yes
Autoconfiguration Yes

Computer 1 192.168.0.2 Preferred
Computer 2 192.168.0.4 Preferred
Computer 3 192.168.0.7 Preferred - This one isn't working
Computer 4 192.168.0.5 Preferred

The Iomega is connected directly to the router is visable on all computers except not working one.
