Snow Leopard 10.6.4 and unable to get IP address from Wireless APs

I have a MacBook Pro with 10.6.4 and just recently ran into an issue in connecting to Wireless APs. Many of my corporate APs with WPA2, etc work great. I even have some great success at customers of mine with Cisco APs and open authentication (ie., Guest access).
However, I have been having alot of problems with generic APs (Linksys, etc.) For example, I have been in two hotels in the past week and I would connect to the AP, but I would only have a self assigned IP address. I have no problems at Starbucks.
I have tried to turn airport on and off, rebooting with no success. I have also disabled my firewall with no luck. The problem is very repeatable.
What do you think?

You might try resetting your connection settings using the steps listed in this message:

They're not guaranteed to solve the problem, but they'll only take a minute or so to try.

I have snow leopard 10.6.8 and want to get on iCloud which requires Lion... should I buy Lion at $29.99 now and upgrade to Mountain Lion when available (I can't see where it is available for download yet) and what is cost of upgrade to Mountain Lion? Or should I simply wait for Mountain Lion?

I would wait for Mountain Lion to be released. According to Apple, Mountain Lion will be released by end of July 2012.
It will cost you only $19.99 to upgrade. You can find all the details at the following link...

Unable to get IP address from DHCP since upgrading

Hi all,
I upgraded my machine to Mountain Lion last night. Ever since then I have been unable to get any IP information using DHCP. Each time I hit Renew Lease within the Network control panel I just get back a self assigned IP address. If I look in the system logs I see the following generated each time my machine tries to look for the DHCP server:
Jul 26 01:32:27 Lightning.local configd[22]: bootp_session: bind port 68 failed, No route to host
Jul 26 01:32:27 Lightning.local configd[22]: bootp_client_open_socket: S_get_bootp_socket() failed, No route to host
Jul 26 01:32:27 Lightning.local configd[22]: bootp_client_bind_socket_to_if(en1, 6): session socket isn't open
Jul 26 01:32:27 Lightning.local configd[22]: bootp_session_transmit: neither bpf nor socket send available
Jul 26 01:32:27 Lightning.local configd[22]: bootp_client_bind_socket_to_if(en1, 0): session socket isn't open
Jul 26 01:32:28 Lightning.local configd[22]: bootp_session_delayed_close(): socket is already closed
I've tried rebooting, clearing the PRAM, deleting Prefs, etc, but nothing seems to have worked.
Anyone any ideas what is going on or what else to try? It used to work perfectly before I upgraded.
Thanks

I am also having this problem since I upgraded to Mountain Lion. I did an upgrade from Lion, not a clean install. I had done a clean install of Lion though. In my case, the network connection is working most of the time, but it is droping one a day. Deactivating the Ethernet and the Wi-Fi adapters and reactivating them does not help.
Here is my what I am getting in the console when I have lost internet connection and I try to renew the DHCP lease:
2012-08-30 6:13:59.158 PM configd[17]: bootp_session: bind port 68 failed, No route to host
2012-08-30 6:13:59.158 PM configd[17]: bootp_client_open_socket: S_get_bootp_socket() failed, No route to host
2012-08-30 6:13:59.158 PM configd[17]: bootp_client_enable_receive(en0): failed
2012-08-30 6:14:00.158 PM configd[17]: bootp_session_delayed_close(): socket is already closed
And I get a self assigned IP.
I hope Apple will have a fix for this soon!
Cheers!

Unable to get ip address from DHCP server for Aironet 1130AG Access Point

I have a network in which DHCP server is enabled. I have read the installation guide also there it is mentioned that 1130G Access point will not have any staic ip assigned to it.So it will automatically get the ip from the DHCP server from the network. I have connected that from the network but it is unable to get the ip address from the same. The same thing i have configured in the netgear it is coming fine. I have seen the sonic wall and used the IPSU tool also from checking the ip address from Mac Address but i am not able to get the same. Please provide me some tips to check where i am wrong in configuration because the first web page also not coming because of the ip address.

narendra,
I would suggest that the AP be connected to a laptop or desktop pc that would run a local dhcp server with a small scope setup...plenty of free ones on the web(this pc would obviously not be connected to your currnet network). This way you can watch the dhcp server hand the AP it's address (this can take a few minutes). Once you have the address use it to access the GUI and give the AP a static address (I find it good pratice to give all my autonomous AP's static addresses for ease of troubleshooting)...Hope that helps.

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.

Unable to get IP address from DHCP

hi all,
I have a AP1131 which cannot get IP from DHCP server. I have tried to configure static IP address and controller IP by lwapp command and the AP can successfully joined the controller. However, after I changed it to DHCP in WLC, it cannot get IP address and all lwapp config is gone. It cannot join the controller anymore only after I reset it and configure a static IP for it. The following error message appears after I changed it to DHCP in the WLC:
*Mar 7 08:44:36.511: RESETTING THE STATIC IP ADDRESS: LWAPP goes back to discovery
%WIDS-6-DISABLED: IDS Signature is removed and disabled.

Any expert has some idea on it?
Thanks.

Is that AP on the same subnet as the other AP's? The thing is, when you configure the AP with static information, you say the AP is able to join the WLC. This means that there is no issue with the AP. Now when you set the AP to use DHCP and not static, the AP does not obtain a DHCP address? Is that correct? If you have more than one AP on the same switch and on the same vlan, and only one has an issue, then maybe reset that AP to default and see if that fixes it. I'm also assuming that the vlan is being forwarded and you have enough dhcp address in the scope.

Microsoft Office 2004 (Word) unable to save files
I have been running Office 2004 on my Intel iMac with Snow Leopard for some time and all of a sudden I cannot save a document. Word just stopped responding and I have to force quit. I can open Word and create a new document but I cannot save it. I reinstalled Word but that didn’t help. Then went to the Internet and found at least one other Mac user having the same problem which it suggests is caused by a recent Mac Security Update:
http://answers.microsoft.com/en-us/mac/forum/macoffice2004-macword/word-2004-wil l-not-open-or-save-documents/b04eb870-9b0d-4f3b-bb47-b122301e36f6
So I check for a new Mac Security Update and sure enough there was one. I downloaded it and now Word seems to be working, as it should. I can both open and save files. The only problem remaining is that when I open Word I get the following error message “An unexpected error occurred while trying to load the Microsoft Framework library”. I contacted Apple but they were unable to help.
How can I get rid of this error message?

Look, I realize you might have to get your machine working, so this is how you revert back.
Restore proceedure to pre-Security Update 2012-001 v 1.0 & v 1.1
#1 Backup your personal data off the machine.
Backup files off the computer (not to TimeMachine). If you don't have a external drive, get one and connect to the USB/Firewire port and simply drag and drop copy your User folder to the external drive, it will copy all your files. It's best to have two backups of your data off the machine when trying to restore.
Disconnect all drives now to prevent any mistakes from occuring.
#2 Reinstall OS X 10.6 from disk
Get out your 10.6 install disk and make sure it's clean and polished (very soft cloth and a bit of rubbing alcohol, no scratches) If your disk is borked, you'll have to order a new one from Apple with your serial number.
Hold c boot off the 10.6 disk (wired keyboard, internal optical drive), use Disk Utility First Aid to >Repair Disk of your internal drive (do not format or erase!!), Quit DU and simply re-install 10.6.
Note: Simply reinstalling 10.6 version from disk (without erasing the drive) only replaces 10.6.8 with 10.6.x and bundled Apple programs, won't touch your files (backup anyway) or most programs, unless they installed a kext file into OS X itself. (only a few on average do this)
#3 Update to 10.6.8 without Security Update 2012-001 v1.0 or v1.1
Reboot and log in, update to 10.6.8 via Software Update, but EXCLUDE THE Security Update 2012-001 by checkinig the details and unchecking the blue check box.
#4 Reinstall any non-working third party programs
When you reboot, make sure to reinstall any programs that require kext files installed into OS X, you'll know, they won't work when you launch them or hang for some reason as they are missing the part they installed into OS X.
If for some freakish reason you get gray screen at any time when booting (possible it might occur when you reinstall older programs), hold the shift key down while booting (Safe Mode, disables kext files) and update your installed third party software so it's compatible with 10.6.8.

That's it really.

Snow Leopard install: now MobileMe and Hotmail no longer working

Hi everyone,
I'm having issues emailing since upgrading to Snow Leopard last friday.
I have 5 different email addresses, of which two are still working and three stopped working in Mail:
* MobileMe account (stopped working)
* 2 Hotmail accounts (stopped working)
* Gmail account (still working)
* XS4ALL webmail account (still working)
I've chatted with MobileMe support for quite some time and have tried the following, all to no avail:
* taking the accounts offline/online manually
* deleting the accounts from Mail and add new ones (with and without using SSL)
* using LAN instead of wifi
* using a few of my neighbors' unsecured wifi connections
* changing ports
* repairing disk permissions
* creating new user account on MBP and then create mail account
* the support agent even created a new MobileMe account
* installing mozilla thunderbird
Basically, when i try to send emails from my MobileMe account or my hotmail accounts, OR when setting up a new account (either using Mail or Thunderbird), i get the message:
"cannot send message using the server [email protected]". If i continue the set up it says it was unable to connect to the smtp server.
Furthermore, something struck me after having deleted my MobileMe account and my two hotmail accounts from Mail. When i quit and relaunched Mail, an email that was in my outbox popped up saying it could not be sent because it couldn't connect to the smtp server, and asked me to manually select another server from a list. In that list the MobileMe account and the two hotmail accounts were still there! After having deleted them..
After all this, MobileMe support thought it was a Mail issue and said i would need to contact the OS X Mail support team. Haven't gotten around to that yet. However, since i get the exact problem in Thunderbird as in Mail, happening right after upgrading to SnowLeopard, I'm kinda thinking it's the OS itself.
Anyone any suggestions? I hope to not have to spend another evening w/ Apple support (however friendly they always are).
Thanks!

I cannot set up my hotmail account. Keeps giving me this error:
"The Hotmail POP server “pop3.live.com” is not responding. Try checking the network connection, and that the server name is correct. Otherwise, the server might be temporarily unavailable. If you continue, you might not be able to receive messages.
Can't say it worked or not before the upgrade to Snow Leopard cause I didn't try to set it up prior.

many thanks Carl.

You must boot from another drive in order to erase the system drive.
Try starting up with Snow Leopard DVD inserted and C depress. That should get you booted from the DVD. Then start Disk Utitlity from DVD and erase the disk then you should be able to install Snow Leopard.
Remember that everything will be removed from the disk when you erase it and install Snow Leopard so backup first.

If a photo is returned to me in a reply does it use additional storage? I am using Mac Book Pro w snow leopard 10.6.8 and an iPhone 4s iOs 5. Yes, eventually I'll free up time to update these. Thanks.

Uh uh, I see!
Also it seems I can use my time machine backup:

together with Migration Assistant. This would work. Thanks
Now I need to figure out the Windows part. I need a full backup of Windows as well, with all the programs. In particular I need to be sure I can maintain the graphic card drivers.
You don't want to know how long took for me to find out how the **** I could update my graphic card drivers in Windows on my Macbook pro. Unfortunately there was a lot of misleading propaganda from Apple about bootcamp, saying that the new intel processor would have worked fine with Windows. Sad that everything was a lie. When installing Windows with bootcamp the graphic card program was unable to find and install the graphic card drivers update . Took me 2 weeks reading through thousands of angry posts of disappointed costumers to find out how to do that. I do not want to reapeat this dreadful experience.
After one year and a half with my Macbook pro I have a system I am TERRIFIED to touch. It is very very fragile, and any little change can destroy everything. It barely works. that's why I am so scared to re-install the OS

Home sharing does not work after update to snow leopard 10.6.4 and iTunes 9

I am using home sharing since about a year without any problems. After updating to snow leopard 10.6.4 and iTunes 9.2 it suddenly does not work anymore.
On my iMac and my Mac Book Pro I get error code 3259 and it tells me to check my firewall and to enable Port 3689.
I did not change anything in the firewall settings, itunes on both allows data traffic in both directions. I also do not find any option to activate a port ( also wondering why this is suddenly now necessary)
I deactivated home sharing on both machines and enabled it again. It still does not work.
On both machines iTunes displays the the library on the left side but like said it is not accessable
With Finder I can access the other computer from both machines without any problem.
Any help to solve this would be very much appreciated

first of all, if you are behind a router firewall, and have your network secured (WPA2 and a long, non-dictionary password made up of letters and numbers), you don't need the software firewall on your Mac(s).
@ least turned if off for troubleshooting purposes.
turn home sharing off on both computers, and make sure
(a) both Macs have access to the internet
(b) iTunes on both machines is authorized for the same iTunes account.
turn home sharing back on on both Macs.
does it work ?
