Macbooks unable to get DHCP from Wireless Network

Our PC Laptops can connect to our Cisco Wireless Network (using wireless controllers and lightweight AP's) without issue.
However Macbooks and several other devices are able to connect and get an IP address via DHCP. If I manually put an IP in the Macbooks wireless configuration it can connect without issue, if I don't do this the Macbooks timeout and say using self assigned ip address and will not get on the network.
Any thoughts on what is causing this and how to fix?

Make sure you don't have client load balancing enabled on the WLAN advanced tab.

Macbook air is unable to connect on hidden wireless network

Dear users and support,
I have just bought my macbook air with lion os already installed, but I am unable to connect to hidden wireless network. Is there any trick to fix it? even though I am typing the name and password it's unable to login.
Please advice.
tks,

Back up all data before making any changes.
Step 1
Take all the applicable steps in this support article.
Step 2
If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 3
This step will erase all your settings in the Network preference pane. Make a note of them before you begin, and recreate them afterwards. It may be helpful to take screenshots of the preference pane.
Triple-click the line below on this page to select it:
/Library/Preferences/SystemConfiguration
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Reset the System Management Controller.

I am unable to join my existing wireless network with new AirPort Express

I am unable to join my existing wireless network with new AirPort Express.
I am using a DLink DI-524 Router, Windows 7 (64), and the AirPort Express.
AirPort Utility will not recognize the AEX wirelessly, it will only recognize it when it is connected by Ethernet. I can then configure the AEX and verify that the settings stick once disconnected and then reconnected. However, even after that, it will not recognize the AEX once disconnected from the Ethernet cable.
I followed the suggestions of several other threads on these forums. But I am unable to get the AEX to work.
Any suggestions? Thanks in advance.

Welcome to the discussion area!
It's almost always a security setting that causes problems when the Airport Express (AX) tries to join a third party wireless network. The AX usually does not "join" correctly and that's why you can't see it on your wireless network using AirPort Utility.
Using an ethernet cable is still the more reliable way to configure and adjust the AX, but if you are want to try to configure it using wireless, you must return the AX back to factory defaults as follows:
Power down the AX
Hold in the reset button +and keep holding it in+ as you plug the AX back in to power
Release the reset button after 10 seconds
When it is set to factory defaults, the AX broadcasts a wireless signal with a network name like "apple network xxxxxx" where the "x's" are either letters or numbers. You must look for this network by clicking on the fan shaped Airport icon at the top of the screen. If you don't see this network, then click Join Other Network to search that way. Unless you connect to this network, you will not be able to configure the AX using wireless.
Do you know the exact security type that your D-Link router is using? That is the key element in the process.
Open AirPort utility, click Manual Setup
Click the Base Station tab to establish a name for the AX, device password and adjust time zone settings
Click the Wireless tab
Wireless Mode....Join a wireless network
Wireless Network Name...must exactly match your D-Link wireless network name
Enable ethernet clients if you want the port to be active (your D-Link must be compatible with ProxySTA for this to work)
Wireless Security...exact setting of the D-Link network. WEP security causes a lot of issues. Try to use WPA/WPA2 Personal, which is far more secure.
Wireless Password...must match the D-Link network
Click the Music icon to enable AirTunes
Click Update to save settings
Any luck?

Problems getting on my wireless network

I am having problems getting on my wireless network. I have never had a problem with it before. I changed the password yesterday. However, I was on it until this morning. I have never had a problem before and I am on it currently with my MacBook Pro. Also, my wife is on it with her iphone. Any suggestions?

I have been having the same issues lately. I have made no changes to any settings on my iPod or router or computer. One minute the iPod connects perfectly and I get 3 bars. 30 minutes later I cannot connect at all to my home network.It asks me for password and then wont accept it, etc., etc.
I unplug the router and plug it back in and it connects. Then 2 or 3 days later I have the same issues.
Got my ipod replaced and still am having same issues. My laptop has no issues whatsoever with the router and staying connected.
Some compatability issue with 3.0+ operating system and home network routers probably. I use Netgear but others are also reporting same issues with other routers.

MacBook can't see my home wireless network after upgrade to OSX 10.8.5

After upgrading to OSX 10.8.5, my MacBook does not detect any wireless nertworks. My iPad and iPhone work fine, my router has been rebooted, WiFi is turned on, and the ethernet connection is how I am writing this message to you via broadband. There are a half dozen wireless networks in range (according to my iPhone) but the MacBook cannot find the router I am sitting next to. Any ideas on how to correct this issue?

It appears an SMC reset was required:
HT5815 I've just done the 10.8.5 update on my MacBook Pro end of 2008, and WiFi don't work after reboot... Impossible to activate it...
Here is your other post: MacBook can't see my home wireless network after upgrade to OSX 10.8.5
If you reply to it and marked it "solved", perhaps with a link to that post (copy and paste it, or just say you performed the SMC reset) it will help others find a solution. Thanks!

Photoshop CS5 Exit Code 7 Unable to get root from inChildPath

I downloaded the trial version 32 bit and 64 bit, to my desktop (Core I7 3.2 GHZ, 12Gb ram, Win XP Pro 64) and when installing, it doesn't get past 0%, just spits out this:
0 fatal errors, 1 error, 0 warning
Error: Unable to get root from inChildPath
Exit Code:7 Unable to complete silent workflow
I wanted to see if the install files were bad, some I copied to my craptop, which runs Vista 32 bit, and it works fine. Any word yet on what causes this error? Going to check and see if I missed any updates while I wait to see if anyone's had this issue.

Using your links, I can find Adobe's listing for error code 7, but all it tells me is that exit code 7 does not define my problem, but the lines that follow exit code 7 do. Which is the "unable to get root from inChildPath" bit. I might have missed something in your post, but when I poke around the links in the document, and in Adobe's troubleshooting search feature, I can't find anything about the terms "root from inChildPath".
Here's a recap of everything I tried yesterday, note that each error is exactly the same:
At the day's beginning, I had Adobe Master Suite CS4 installed, including PS CS4.
Without un-installing, I attempted to install Photoshop CS5 Trial > Got the error
Copied PS CS5 files to laptop, which also has Master Suite CS4 > Installed fine
Uninstalled Photoshop from Master Suite, then installed PS CS5 > Got the error
Tried to install only 64 bit > Got error
Did "Run As", signed in as admin > Got error
Booted into Safe Mode to install to see if a background process was conflicting > Got error
Reinstalled Master Suite for 6 hours and quit trying...

After loading yosemite can't get permissions from any network PC - OK from MACs on network...any advice?

after loading yosemite can't get permissions from any network PC - OK from MACs on network...any advice?

would love to...way over my head so far...upgraded to Yosemite 10.10.2 - I have another MAC (motorola chipset...maybe 10.6?) and 3 PCs on the network...the older MAC linked up through the network just fine...
I can see the Yosemite MAC on the PCs...I can open customer file folders (I am a printer) from the shared drive...I can drag files (let's just call them PDFs, they mostly are) to the MAC customer file...but if I try to open them from the PC I get an error message that says permission denied - or may be in use by another user. There are no other users. After I uploaded to Yosemite, I noticed most if not all drives and or folders had permissions changed to either no access or to read only...I've changed as many as I could find...drives, and folders...I can open those same files if I'm on the yosemite mac...Here's the catch, though...I was on a different floor and that PC can open a PDF on the Yosemite...but the RIP that prints our large format prints now won't print those files (whole RIP locks up) unless they are first dragged to the PC desktop...then all is fine. I thought it was MAC upgrade oriented, but I do have a PC that halfway works...I'm really stymied...

Guest VLAN unable to get DHCP IP address from Anchor Controller

Hello everybody,
In our test set up, we have two WLC 5508 Controllers connected via Checkpoint UTM-1 firewall Inside and DMZ Interfaces. Both the WLC controllers are connected to the firewall via Cisco 3750 switch. On the Local (Inside) Controller, guest SSID is enabled and attached to the wireless management Interface. On the remote anchor controller, guest SSID is enabled and attached to the Management Interface as well. The following configs are replicated on both the Controllers.
SSID Name - guest
Interface - Management ( VLAN 10 on Local and VLAN 20 on remote) -
Mobility Group: Same configs at both ends
SSID Anchor : Anchor SSID on local and local SSID on Anchor.
AP: CAPWAP 3502 Management Subnet
SSID Security etc all defaults and matching on both ends
Checkpoint Firewall Rules: Allowed 16666-7, IP 97 etc on the firewall
Checkpoint Inside/DMZ to Outside(Internet) is NAT enabled.
EoIP Tunnel Status: Up, UP - Both ends
Mping - OK
eping - OK
WLC Sofware Version on Local - 7.0.98.0
WLC Sofware Version on Local - 7.0.116.0
DHCP Scope: Definitions on Anchor Controller and Guest Anchor SSID points to the Anchor management IP as the Primary DHCP server.
Management IP Subnet on Local: 10.x.x.x
Management IP Subnet on Anchor: 172.x.x.x
The problem definition as follows:
When guest SSID associates to the local AP, the guest SSID never gets a DHCP address assigned from the Anchor Controller and the following debugs are obtained.
1. WLAN ID 1 (for Guest SSID Number) delete message appears in the Controller message logs, but the SSID does not DHCP from the local Management Subnet and i can see DHCP request via the tunnel to the Anchor WLC as follows:

Is there any thing missing in the wireless configs and or the firewall rules as i could not see DHCP request back from the Anchor Controller. Also, after DHCP is obtained, the web authentication request will be redirected to an Amigopod device for authentication. In this case is the redirect URL congiguration to be performed only on the Anchor Controller or is this to be replicated on both the Local and Anchor Controllers.
Thanks and Regards.

The DHCP issue is resolved if external DHCP server is configured on a 3750 switch connected to the WLC and the default gateway for DHCP points to the Firewall, which is in the data path between the Inside and Anchor Controllers. DHCP is essentially bridged (no Proxy setting now) from the EoIP tunnel to the Distribution system network. We will test this solution on pilot production and then consider upgrading to 7.0.116.0, as there are about six offices running 7.0.98.0, which will need to be upgraded.
For L3 security, configuration is set up on both the controllers for external captive portal redirection.I will try this only on the Anchor and revert.
Thanks again very much for all your help.

WRVS4400N Unable to get DHCP address via wireless

I am having an issue with the WRVS4400N. I am unable to get a DHCP address via wireless. If I connect directly to the router via RJ45, I get a dhcp address an and able to get to the internet. Has anyone ran into this issue.

This seems to be a problem with the latest firmware (v1.01.03) available from Linksys for this router. The stock firmware for my WRVS4400N router assigned DHCP addresses to wireless devices without any issue. As soon as I upgraded the router to v1.01.03, the router no longer assigns DHCP addresses to wireless devices. I have verified there is no issue with the router itself by rolling back to version 1.00.16 with the recovery utility.
One workaround I noticed with firmware v1.01.03 is that the router will actually assign DHCP addresses to wirelss devices temporarily if it assigns a DHCP address to a device connected to the physical port. This only last for a little before the router stops giving out DHCP address to wireless devices though. It's a shame since I was looking forward to some of the features in the v1.01.03 firmware.

Macbook (10.4.11) unable to connect to one wireless network

We have one student who is unable to connect to our student wireless network. He's using a Macbook (black) with 10.4.11 and all updates. He's got a stock Airport card. We have an Airport Extreme broadcasting the network. Other students are able to connect without any problem. He's able to connect to our teacher's network without any problem.
When we try to connect his airport to the student network, it reports "There was an error joining the AirPort network 'Riverstone Students'." No further information is provided. I've tried removing it from his preferred networks, removing the key from the keychain, and reconnecting, but no change.
Any suggestions gratefully received!

Just found out a little info about my work network. We are using a SMC Network 8014 W-G broadband modem and a Linksys WAP11 Wireless Access Point, and the security is WEP. I have tried to login to the device webpage to check/adjust settings but nobody here knows the password and "admin" doesn't work. I really don't want to do a hard reset and take the chance of screwing up the network for everybody in the office (apparently it was quite complicated to set up when they first installed it, I wasn't around then). Does anybody have any other ideas? Thanks
