I run a wireless network with an apple base station. I have two PC,and an imac. The router runs through my pc and my imac and laptop pc run wireless. My imac has been taking up to 3 mins and most of the time the system timeouts anyway, but yesterday an interesting msg popped up on my laptop, that there are conflicting IP addresses.
Any solutions?

On the PC follow this:

Start
Run
type "cmd" (minus the quotes)

In the command prompt type:

ipconfig /release

Perform a reboot once the command has completed and this should select a new IP address, assumming you are using DHCP.

If you are using static IP addresses ensure the Mac and PC haven't been set to use the same address.

You shouldn't need to reboot the laptop -

ipconfig /renew

should IIRC get a new IP address for the laptop, no restart required.

Use ipconfig /all to find out if you are using DHCP.
Usual to set a fixed ip address for the base station and variable for the others. If you are getting conflicts using DHCP then there are probably connection issues elsewhere within the system that might also need resolution. Might also be worthwhile decreasing the lease duration of the ip addresses.

I've had it happen many a time where doing a renew after a release actually picked up the offending IP Address. A reboot is the easiest way to ensure the Windows machine will capture a new address properly.

Macs on the other hand don't need the reboot because they aren't dumb.

Thanks for the suggestions, but I have tried a few things such as reconfiguring etc and now I am able to connect to the internet occasionally but it is taking several minutes and either times out or doesnt load web page properly.

I have gone through network diagnosis several times with no success.

Okay trying to work out how your network is configured.

Does your network look like this:



By way of an explanation I'll lay it out.

First we have the ADSL/Cable connection for the Internet which is connected to the Airport.

Then we have both the PC(s) and iMac connected via Ethernet to the Airport (I'm assuming you have Extreme) and the laptop is connected via wireless.

Is this correct? Sorry, I just couldn't work out how it was setup from your explanation.

I've written up a quick tip about setting up the Airport network here:

How do I share a modem connection using Airport routers?

This might help a little. It almost sounds as though somewhere there is a setting on one of the machines for a static IP address that is conflicting with the router and thus causing the PC to throw the error. The conflict may also be what's causing the Mac to spit the dummy as well.

Thanks for the reply. I'm going to pull my system apart but first I will draw a picture and compare it to yours, then i will reset it up i'll get back to you in a day or too as work is a bit hectic but thanks for the help

Hi Lowededwookie . The Laptop and imac are both wirelss. I am still trying to work this out. I have reset base station both soft and hard reset. Discontected wireless and re installed software on laptop for d-link adaptar. The thing is up til about 2-3 weeks ago the system worked without a hitch for a very long time.

Actually I am beginning to think there is another problem I tried antother wireless router yesterday and that won't work as well and it did so successfully to using the apple extreme, so I have now connected directly to the modem for the internet,and I have been trying to download the latest software updates but all I get at the end is a red exclamation mark and a msg saying check that you are connected to the internet. I have also had an ongoing mail problem - slow to load and on loading it is empty and to retreive any previous emails and have to push get mail.
Internet is very slow and sluggish and have spoken to my internet provider many times checking the connection is correct on the pc that is connected to the modem. I will try taking my imac to work to see if it has any problems as we run a pc, imac and three ibooks off thesame network with no problems at all in fact it is set up the same as I have at home. ????????
Recently another wireless network has appeared (must be one of my neighbours) and is obviously in range! Could this be a problem????

So anyway....
I took my imac to work plugged it in turned it on and instantly connected to works wireless network - apple base station.
