Conflict of IP address

pipsqueak10 · Post by **pipsqueak10** » Mon Dec 27, 2004 8:32 pm

I have 3 comps on a wireless network. One is wired directly to the modem and router(linksys). The two other comps have wireless adapters. I've had the network for at least two years without a problem. However, now whenever I have two of the comps connected to the internet simultaneously I get a "conflict for IP address xx.xx.xxx.xx with the system having hardware adress blah blah blah blah." error What gives?

Check the IP Addresses of all of your machines and make sure each has a unique IP address. If two of the machines have the same IP, change the 4th octet number to something inbetween 1-254.

Just have all the pc's automatically get the IP's via DHCP with the router.

Yup, that worked for me ... same config (1 node hardwired to router, 2 wireless nodes).

I have a similar problem: 3 pc's on a network which runs fine. If I have a LAN with 2 other people, I get the "network conflict" message.
However, I use generic IPs for the LANs (192.168.1.xx), and all of the machines have a different IP...however, my wife's machine ALWAYS gives me that error when I hook up the LAN....I have no idea why this happens....

Either set ALL PC's to use DHCP or manually set ALL PC's to a 192 IP range and you won't have ANY problems.

Thanks for all the advice. Here's how I fixed it. I did absolutely nothing, made no adjustments whatsoever and the error message just went away.

Pip, I'd suggest doing one of the two things I suggested. Your problem will come back again.

Yup, you're right, it came back. How exactly do I have all the pc's automatically get the IP's via DHCP with the router?

The router should already be setup for it unless it was turned off. FOr the PC's, just go into TCP/IP properties and select "automatically assign IP" or something similar. Make sure nothing is check or any IP entered. Then reboot each PC.

Assuming your wireless network is secured? Does your wireless point/router let you see the wireless clients connected?

Just wondering if someone else was connecting to your network...

Okay, she's fixed. Internet properties say the address type is assigned by DHCP on all comps. Thanks for the help.

Must say, that for small home networks, I prefer to disable DHCP, just because I can always remember what IP addies the various boxes are.

I have my computers on static IPs because I run programs and servers that require open ports.

Internal IP: Start > Run > cmd > ipconfig (WinNT/2K/XP)

GD, do any of you people read the manuals anymore?

in fact with all routers you just plug it in. DEFAULTS do the rest!

My Network Places->View Connections. Right click on the connection being used (WiLAN or LAN), then go to properties. Either choose all to get the IP address or manually assign all. If you choose all to get the IP address (recommended) (also known as DHCP), then after that
Start->Run->cmd
type "ipconfig /renew" on all computers.

I have 3 PC's wired and 1 laptop wireless. All on the same router and it all works fine. Read the manual and do some research you will have no problems getting them all to work.
