I have two laptops on the same network. When one of them is on, the other cannot get on because of this IP conflict, and vice versa. How do I change one of the IP addresses so I can get both laptops on the network at the same time? I'm looking to transfer music between two laptops and because they both can't connect to the network at the same time (Mac and PC), I can't transfer the files.

I have a wireless router with 2 devices connected via ethernet (PC and XBOX 360) and 3 devices connected wirelessley (Imac, macbook, iphone and printer). This morning I was using my imac and all of a sudden I got a message saying another device is using my IP address.
I tried restarting the router, the computer airport but nothing worked. The only other device on at this point was the macbook which received the same message. I assigned a manual address to the imac via the advanced settings in airport but how do I fix this so that IP addresses are assigned automatically?
I have about 60 users on my network with a router assigning DCHP leases to all machines.There is an airport extreme in bridge mode which is expanded with another airport extreme that are connecting the router to about 35 machines. There is a 50/50 mix of mac and pc.ONLY the macs are having a IP conflict issue.
Problem:IP Conflict errors only on the wireless connection throught Airport on Macbooks.I did have 1 iMac have this problem, but they are fine for the most part.It seems the MAC just will not let go of its previously issued address and is persistently re-asking the router for the address, kicking back the error.I try to have it clear the previous DCHP with no luck.
I have tried:
-Renew the DCHP lease
-Reboot Machine
-Repair Disk Permissions
-Update Software (Happens on both OSX10.6 & OSX10.7)
-Remove/Recreate Wireless Network ProfileÂ
If I just assign a manual address, it works. I don;t want to do this to everything on the network and I would love for the DCHP to work as it should on the MBPs like it does on everything else. Rebooting the router is not an option since I have an entire office on it. And.. it is probably not a router problem since the problem is concentrated on one type of machine.Â

Girlfriend just got a new iMac all in one a week or so ago. We had no problem setting this up on the exsisiting network but a couple days ago we began having issues. The 3 PCs, 2 iPods and one network printer seem to connect fine until the iMac connects (or tries to). We've gotten IP confilct errors on various machines (assigning already assigned IP address). I cannot even connect to the router when the iMac causes this problem. Take the Mac off, everything runs fine. I am new to the Mac world so maybe I'm missing something. Here's what my network consists of... Scientific Atlantic DPC2203C cable modem (Optimum) Netgear WGT624 v3 router 1 iMac all in one, 2 HP and one Gateway PC(all Vista), 2 iPod touch, 1 HP wireless printer all running DHCP and wireless.
View 6 Replies View RelatedUsing a G4 IBOOK with OS 10.5.8. Recently converted IBOOK from just my wifes computer to both of us so it is now dual usuage with both of us signing in to our respective files/e-mail, etc. My side has a problem never experienced before. My apple mail system address book has all the names the dock address book does but is missing almost 2/3rd of the actual e-mail addressess. I have tried to redo the dock address book in hopes it would change the "internal" mail book, but to no avail. It id difficult to add a recipient to an outgoing e-mail via the dock address instead of the apple mail address book.

This morning, while I was downloading some files, my internet connection died on me. At 1st I thought it was my provider and I usually fix that by restarting my Router. I did that, but nothing happened. I could detect and connect to my WiFi but I had no internet access! My wife's PC and mobile phone connect perfectly well to my WiFi and so does my iPhone!!! My MacBook now only works with Ethernet. Let me add that I have the 13.3" MacBook unibody running the latest Leopard 10.5.8. software upgrades.

View 2 Replies View RelatedI have a brand new 13.3" 2010 MacBook Pro 2.4Ghz. I also have a 24" iMac and a new Mac Mini. I am using a Buffalo WHR-HP-GN as my router and wireless connection. The iMac and the Mini both connect to the network at "N" speeds while the new MacBook Pro only connects at "G". I have tried everything but it will not connect at "N". It will connect at "N" at the Apple store, so it seems strange that one out of three computers will not connect.
I also have an MSI Netbook with OSX 10.6.3 and it also connects at "N" speed. Does anyone have any ideas? It seems like I am not the only one having this problem as it is mentioned on the Apple forums. Tech support was unable to help, so they escalated my case, what ever that means.
I can not seem to sync my mac or enable "back to my mac" because I am being told that "I may have more than one device on my network providing Network Address Translation. Well, this is news to me. I have a Time capsule running my network and an Airport Express with Airtunes dvice and they have been hooked up for more than two years. I have been abloe to sync my network up until recently and I do not recall making any changes to any network configurations so I am clueless as to why things suddenly stopped working in this regard.
THe error message tells me to disable Network Address Translation on one of the devices but does not tell me how to do that. Nor can I find any information related to Network Address Translation on the help database.
Does anyone out there know how to do this?
When I try to connect to a wireless network. It says there is no IP address? I know nothing about computers. The mac shoppe told me I needed to erase everything and re-install my software. I did this, and it still doesn't work. I'm very frustrated because I lost everything when I did this!
When I connect directly to the modem, it works fine.
I used to know a command that would show all of the ip address and the name of the devices on your network. I have not use the command in a while and I forgot it.

View 2 Replies View RelatedI'm running snow leopard on Macbook Pro. My college has free internet access and every hostel has different IP addresses assigned. My hostel has this IP address 10.165.x.x. The students keep changing their IP address and somehow my macbook pro disables me from accessing the internet when a windows OS user in the network uses the same as mine. Somehow windows OS doesn't allow the second user to use if its already taken but my poor mac OS allows it even while m using and I'll be thrown out. I'll have to look out for a new ip address which is not taken already. How I can protect my own IP address?

Info:Mac Pro, Mac OS X (10.6.2)
a macbook air and an iMac have both give the error "Another device on the network is using your IP address". They are both using the latest OSX and are both set to use DHCP assigned by my Virgin cable router.the address reported in the popup window is NOT the address that either computer was assigned at the time (the first time, I thought it was odd, and I had an iPad handy and used fing to search my network to see what device had just used that address and I didn't see anything). This time - I was on my iMac and happen to have a terminal open, so I did a quick if config - and my ip address was not the one indicated in the message (it was saying 192.168.0.8) and my address was 192.168.0.12. In fact I think that the other day it was complaining about the same .0.8 address.
I do have 2 devices that have a hard coded ip-address (but they are right at the beginning of the range, and in fact I have instructed the router to skip those addresses and just dish out ip's from .0.3 onwards). All other devices use DHCP.Â

Also, any way to fix the Type 1 Helvetica Neue/ Snow Leopard conflict?
it seems that both Time Capsule and Leopard Server both use port 548 for file sharing. So if I have both the server and Time Capsule with File Sharing turned on, any attempt to login will go to the Time Capsule and not to the server.
If I turn File Sharing OFF in Time Capsule, I can than map port 548 to the IP of the server machine and users can properly login into the server again.
Can any one tell me how to determine the IP address of a network printer. I have an OKIpage 12i which suddenly can't be seen via Appletalk, so I was going to try to connect to it using IP (which is how I connect to the Xerox Phaser we also have)

View 3 Replies View RelatedI am a comitted Mac switcher trying to put my lovely new MacBook onto the office Windows network. I can connect to the office wireless network (WEP key etc) and the little radar Icon in the menu bar lights up. However, I cannot get the MacBook to obtain an IP address via DHCP. I just keep getting the default self assigned address (169.....).
However, when I connect to the network via a cable using the built in ethernet connector, I get the DHCP address just fine and everything works OK.Also, if I assign an IP address manually to the wireless card (checking it is a free address!) it accepts the settings but I cannot network, not even a basic ping of another machine on the local internal network (all our internal machines are using 10.0.0.x addresses and 255.255.255.0 sub net)The DHCP server is not in the wirless router but is a Windows server machine.This is driving me crazy. I have called Apple care and they just dont want to know because there is a Windows machine in the mix. I expected better from them,
