IP Address conflict...


Howard Woodard

I'm not sure if this is the right forum for this but I'll start here.

I have a home network implemented with a Linksys WRT54G. My computer, a HP
printer, and a DSL router/modem are connected directly to the 4 port switch
and my wife's computer accesses it via the wireless access point (WAP).
This has been in place for a couple of years and works just fine.
However -- there's always a "however" isn't there -- the last couple of
days my computer has been popping up at random times with:

Windows Systems Error
There is an IP address conflict with another system on the network.

When I look at the address table in the 54G all of the devices have
different IP addresses and nothing seems to be adversely effected.

Does anyone know how I can narrow this down and correct it?

Are any of the machines set for a static IP while others are set for dynamic?
If so, check the static IP and make sure it is not in the same IP range as the
DHCP range. If the static IP is in the same range as the DHCP range, change the
static IP to an IP not in the DHCP range.

To check each machines IP configuration:
On each machine click Start > Run, type in: cmd

At the command prompt type the command below only, not the note, and press
ipconfig /all *Note space in command before /*

If you wish you can save them to a text file and post them in this thread.
At the command prompt type the command below only, not the note, and press
ipconfig /all >c:\ipconfig.txt *Note space before / and >*

Open ipconfig.txt in notepad on each machine. If the contents aren't
wrapped/showing properly, on the Menu bar click Format and select "word wrap".
Copy the contents and paste into a response to this thread.

Which of the two are you using as DHCP server, the DSL router/modem or the
4-port switch?
You can only have one DHCP server in a LAN. I would recommend setting the
DSL router/modem in bridge mode (check you manual) and the Switch as the
DHCP server. I like assigning IP address to each of the connected machines.
