Hardware :: Airport DHCP Fails To Get Address (Mac On Windows Network)?
Jun 7, 2006
I 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,
I've recently purchased my first Mac (the new 13.3 inch air model). I seem to be having a bit of a problem with wireless networking, though. It seems that my Mac will reconnect to my wireless network perfectly after resuming from sleep mode just fine for a few days, but after those few days, it will mysteriously stop being able to get an IP address from the DHCP server (my wireless router). My PC is able to connect to the network just fine and always seems to be able to get a new address, but the Mac just loses the ability. I have found that the only way I can get the Mac to start grabbing an IP address from the router is by going into the router settings and changing the RIP mode to a value other than what it currently shows. I generally try to stay in RIP_2B mode, but I change it to some other random value whenever it stops connecting.
When we share internet connection through ad-hoc wireless network, each individual connecting to our network will be assigned with an unique IP Address and other required fields will be filled with proper data(Gateway and ..).
I used this feature to access my iPad through wifi, and had no intention of sharing an internet connection. Now that I don't have an internet connection to share, my computer doesn't give any IP to my device, therefore my computer is unable to see my iPad on the network.
I also tried "Create network" feature of mac, but again, since IP addresses have been assigned by self, I'm not able to see my iPad on the network.
Having trouble on my mac while trying to connect to the internet using the built in Ethernet.
It says under network: Built in Ethernet is currently active. Built in ethernet has a self assigned IP address and may not be able to connect to the internet.
I hit the IPv6 and/or DHCP and it locates a IP just not a router number. Is this what is stopping it from connecting? Please help as I have an AP test I would like to study for....
I own a MacMini Server in my home network with Lion Server installed. I configured the DNS Service with a primary zone, providing nameserver (MacMini) etc. Server Admin tool create also a reverse zone 0.0.0.10-in.addr.arpa (my IP Range is 10.0.0.I own also an Airport Extreme Base Station (4th Gen) acting as DSL Modem, DHCP and NAT and creating 2 Wireless networks (private and public network) and it's correctly set up for internet access... In AEBS settings the DNS Servers are 10.0.0.3 (MacMini) and 8.8.8.8...With these settings everyting works fine but all the devices (other Macs, windows PCs, etc.) cannot ping each other... The only machine they can ping is obviusly the MacMini because in the DNS settings i punt manually a machine (A) record...
My question is: is possible to setup Lion Server to dinamically update DNS records using AEBS DHCP entries and reservations ? If possibile i don't want to add all the record manually and I don't want use the AEBS only as an access point...

After initially installing win 7, and taking a few stabs at the correct driver for the wireless card in my mac pro (apple installed), i got wifi working with a public network.
HOWEVER, i installed windows updates, restarted, and now it's just not working again!
it says that there is not a valid ip address... my macs get on fine...
how to diagnose and fix? the win 7 dianostics do nothing.
I have a Mac OSX Server (10.4) connected to a switch with various Airport Express terminals around the place. Macs can connect to the network wirelessly (with 128 bit WEP) and WIRED totally fine... but when I try and connect a windows PC either using wireless or WIRED... an IP address isn't assigned. Windows just says "Limited or no connectivity"...
We have some Education iMacs that I am having some problems with. XP can be fully up to date (except SP3) without any problems, they are connected to the domain, get an IP address, correctly sync time and process group policy settings at a computer level prior to the logon screen. All this is using the ethernet port (not wireless). As soon as SP3 is applied, they don't get a DHCP address until after login, therefore they don't sync time, process policies etc. If I uninstall SP3, back to working. I have reproduced this several times on different Macs (we have about 90 that are exhibiting this). Tried different version of bootcamp drivers.
If I reserve the address in DHCP, it doesn't make a difference. I seem to only have 2 options: 1. Manually enter an IP address in Windows (this is too time consuming) 2. Leave SP3 off (this means WSUS 3.0 SP2 won't work) Is there a newer ethernet driver outside the bootcamp package?
This is driving me insane. Just got a new Centrino laptop (obviously with wireless), but it refuses to see the AirPort network. I have reset the base station so there is no encryption of anykind, but still no joy.
Is there anything that needs to be set on the AirPort for this to work?
I use VPN to connect to my work. Sometimes I leave it on when I stop for the night. When I go into work, I usually can login to my laptop either via VNC or ssh even when the tunnel is enabled. But, now my laptop becomes totally unresponsive and unable to receive or initiate connections.After I came home, I tried the basics. DNS completely failed. Connections to my local network seemed to work OK (192.168.1.X). However, anything else was not possible. I tried running nslookup to see what was happening. [code] I tried using ifconfig to take the network interface down and then back up. I tried disabling and re-enabling wifi. About the only thing I've been able to do is reboot the machine.
If someone has me in their address book as Doe John and sends an email to me at my email address (johndoe@mail.com), Mail.app does not recognize me and asks me if I want to 'Add to Address Book'. The same happens if a sender has a minor change in the Name (such as even a dot in the name) of any recipient, regardless of the fact that I have the correct name in the address book. Mail fails to recognize the recipient even though the email address is identical, and will ask me if I want to 'Add to Address Book'. One would expect Mail to use just the email address and recognize the contact as already being in the Address Book.
I my printer connected to my airport express and am trying to print from a XP machine. I have installed bonjour and found the printer and set it up and everything. It is available as one of my printers from the print screen in XP. Everytime I try to print the job fails.
Suddenly the networking functionality has stopped working and the diagnostics fails to fix it. It shows all green lights apart from Internet and Server which both show as FAILED.
My router is operational and does assign the Mac Mini the correct IP address (confirmed by the Mac Mini and the Router). All other devices on the network work and can access the internet as usual.
I have tried everything that I can think of but just can't get it working again.
The same symptoms occur for both the wired ethernet and the wireless connection with the build-in airport.
I have an Airport Extreme, with two USB hard drives connected to it. The Airport Extreme shares these disks to my wireless network via Airport Disks.
Upstairs I have an Airport Express, that wirelessly connects to my Airport Extreme downstairs, and extends the wireless network so I get a good wireless reception upstairs.
My problem is, that it does not seem like me Airport Express does a good job of forwarding my 2 USB Airport Disks to the extended wireless network upstairs.
For example, when I use the AirVideo iPhone app to stream video from my USB Airport Disks I get a server connection error when I go upstairs and the iPad/iPhone switches to the Airport Express networks. I cannot reconnect as long as it is on the Airport Express network. If I turn the airport Express off, and thus switch to the poor wireless reception from the Airport Extreme, I can connect to the USB Airport disks again.
The Airport Express is connected to the Airport Extreme in bridged mode.
I have a slow network issue. I'll try to make it as simple as possible.
1 MacBook Pro 1 Airport Extreme 1 Airport Express to Extend the Network
The network to my living room was slow, so I added the Express to extend the network. When connected through the Express, with a Time Machine backup, I'm getting about 500K/sec transfer speeds. When I move the laptop away from the Express and close to the Extreme, the network works much faster, about 5MB/sec. I don't understand why the network is so much slower when using the Airport Express as a network extender. Is the speed difference normally that much? If it's not supposed to be, is there anything I can do?
Here is my situation. I am a network newbie. I bought a Airport Extreme (2008 model without dual band & guest networking) and have it setup with my ADSL broadband modem. I bought it so I could use the high speed N to connect to my Apple TV. It replaced a Linksys WRT54G.
My concern is this. We have another laptop in the house which only has Wireless G. It is connected most of the time to our network, so I presume that it will be slowing the speed of my Extreme to G levels.
Can I connect my old Linksys G router somehow to my network to create a seperate Wireless G network to access the internet. The older laptop can be at G speeds and my Extreme network remaining at N speeds ?
Maybe an easier option is to buy a N USB adaptor for my laptop but I don't want to buy something if I can use my current equipment.
I have: Power PC G5 dual 2.3 w 10.4.11 os, Lost Internet connection. (ethernet cable direct to router), No known cause. Checked router,cable etc. All work fine w other computers etc. router does not "see/read" when cable connected to G5. I figured Ethernet card is dead. Can't afford new card figured I'd try: Net gear G54 wireless USB adapter, just to get back online. Downloaded driver for Mac etc. Went to System Prefernces to set up. Opened System Preferences then Network, Automatically this message drops down: "Your network settings have been changed by another application" When I click "ok" same message automatically drops back down. Cannot access "Network settings" at all.
For some reason, iTunes 10.1 will not fully launch. When I bring up a list of the Task Manager processes, I can find the itunes.exe process- but the program doesn't ever run. I've tried a lot of methods to get this to work, including installing an earlier iTunes version, but when I tried to open the earlier iTunes, it wouldn't accept my iTunes library, stating that it was from a newer version of iTunes.
I've also tried a system restore, but the restore function could not be completed and now I am completely lost on what to do- including replacing the core audio toolbox.dll file Any suggestions?
I would like to say that this is my first post on the forum. Here it comes;I'm new with mac and would like to install windows on my black 3.1 Macbook. Boot Camp continuously fails at partitioning. I've read many articles about it which say iDefrag is the solution. So I did some defragments with iDefrag (the on-line, compact and the full-defragment) and tried to partitionate with Bootcamp lateron but it did not work. What should I do to fix this.
I've searched everywhere and have one nagging issue. After I uninstalled Parallels I keep getting two Parallels Virtual Network Connections under Network in System Preferences. It happens every time I restart, I have to redeleate them. Has anyone had this problem after uninstalling Parallels?
I'm having grief trying to create a new windows partition on my MCP. This is a similar problem to a million others that I've read on google, but slightly different and I cant get to the bottom of it. So, I had a 100GB hard drive running 10.5 and created a 20GB partition for XP. All good, all worked. But 20GB wasnt quite enough so I purchased a new 160GB drive and used Carbon Copy Cloner to create an exact copy of my OS X partition on the new drive. Removed old hard drive, installed new one and OS X runs like a dream still.
However, now I go to make my windows partition using bootcamp assistant and get the following error: "The startup disk cannot be partitioned or restored to a single partition. Back up the disk and use Disk Utility to format it as a single Mac OS. Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again." Thing is, there is only one partition on my drive when I look in disc utility. I could just format the drive and restore using carbon copy cloner I guess, but I'd like to avoid that hassle.
I am converting from a Windows system to a Mac. The mail client on the Windows box is Outlook 2003. The mail on the windows box had been previously stored in a number of PST files using POP3. The recommended procedure to convert to the Mac is to first in Outlook 2003 convert from POP3 to IMAP. While in the middle of this procedure I got a message that the PST file that Outlook 2003 creates for the local IMAP store is full. Further, it is 97-2002 format file rather than the new type used as the default in Outlook 2003. In any case, I need to get the rest of the mail converted. Another issue is that viewing specific folders in the IMAP store on the Windows box results in an initial display of items, followed by the window being cleared, and the folder size function showing that the folder is empty. However, attaching to the IMAP store on the server from the Mac Mail program still shows the contents, so I think this is an anomaly of the poor implementation of IMAP in Outlook 2003. What do I need to do to get the rest of the POP3 mail into IMAP?
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.
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 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 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.
I just secured the wireless router and network for my roommate the other day. When I got back in town today and tried connecting to the internet, it told me that another device on the network is using your computer's IP address. I have no idea what this means and what I have to do to fix it... any thoughts?
I'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?
