Macs & Open Networks
Ok,
I admit that I know very little about networking, and I'm sure someone will correct me if I'm wrong about any of this:
There is an open wi-fi network on our installation, and PC users are not having a problem connecting to it. However, my MBP and two iPod touch users can connect to the network, but do not have internet connections. We've tried disconnecting the power to the router for a little over a minute, and still no luck.
I have told everyone this is not an issue with Mac because wi-fi is a standard, and Apple adheres to that standard. Is it possible to lock out Macs only?
It's an 802.11a/g network.

Check in System Preferences > Network > Airport > Advanced >TCP/IP for the IP address. If it is 169.254.xxx.xxx, it is not receiving an IP address from the router (this is a self-assigned IP address).
If you have noticed that any new client joining the network shows this self-assigned IP address, it probably means that MAC addresses must be added to the address control list of the router.
If there's no access control list, check for firmware updates for the router.
If your IP address starts with 192.168.xxx.xxx, you can try the following:
You can find the router address in System Preferences > Network > Airport > TCP/IP. If you go to this address in Safari and it opens a router configuration page, you know that you're connected to the network and that Safari works, so the router may just need to be reset.

Hello,
I realized recently that I should have had this on a more visited Networking forum, and since it really applies to all OSX networking. . .
can anyone comment on this post?

LawrenceLawrence, Listen to Jonny. Find out the IP details of the machines. If there is no security in place then there is no security in place. The only restrictions possible outside of a password or certificate based security systems is MAC address filtering (which you've confirmed is not in place).
Jonny is trying to determine if the Macs are getting IP addressing from the wireless device. Connecting to it is one thing. Getting an IP configuration from it is another. If they are not getting configuration details from the router, they cannot connect to anything.
Post back the info you get. In particular note if it is a 169.254.x.x address as Jonny has requested. If it is, then you can tell the guys with the problem that the router isn't distributing DHCP info to them (which may be useful info to someone there) while you're waiting for some more help from us.

My ISP has just installed a new modem with an ethernet connection, which I have plugged into my Airport Express. I'm able to connect to an open network in the neighborhood but not to my own network that I had set up before. I have done some troubleshooting, the modem is working when connected to my computer. It may just be the password, it's not accepting the password that I thought I had used to set up the Airport Express when I first bought it. Should I be using the same password as in my Accounts on my Mac's System Preferences?
... Would the network password be the same as my Mac's password?
It can be if you configured it that way, but since that is apparently not working for you it's probably not the same. You can reconfigure the Express easily enough using AirPort Utility - it is in your Utilities folder, which is found within your Applications folder.
Launch AirPort utility, then reset the Express:
To reset your Express:
Press and hold the reset button with a pen or pencil for 1 full second. The light (LED) will flash amber, indicating that the AirPort Express is in soft reset mode.
This will enable you to use AirPort Utility to reset your network password.
Note: If you do not make your changes within five minutes of pressing the reset button, AirPort Express will return to its previous configuration. The light will change back to solid green (or whatever state it was in before the reset).

Unable to open Network System Preferences
When I want to open Network System Preferences I get the message "Your network settings have been changed by another application". When I click "OK" the message keeps reappearing. The only way out is a Force Quit of System Preferences. What does this message mean and what can be done about it?
Maybe it's worth mentioning that I had to reinstall Mac OS a few days ago due to a screwed up security update. Could it have something to do with that? Apart from this my iBook works fine and I have no networking problems.
Thanks for any helpful advice.
PaulHi John
That didn't work but thanks anyway.
In the meantime I found another topic under "Mac OS X Tiger" that I had overlooked before dealing with this problem. It obviously has to do with the latest security update.

Auto-assigned IP address on an open network
Hi Mac users,
I guess somebody else has already had that problem (or I would really be the unluckiest person in the mac world), but I can't find any solution to it, so PLEASE help me!
I have had my MBP for 6 months, it came with Leopard, and in November I upgraded to Snow Leopard (with someone else's CD that I can't get back do please don't tell me to do a clean Snow Leopard install). I'am not really a Mac pro cause I used to be a Windows user (yeah I know) and I never really got any problems with my Mac so please explain clearly if you have a solution for me!
Here's my problem :
I need to access an open network at my school. You're supposed to connect to this network without entering any weep or pa key, than you get to a page where you login with your school information. Then you get full internet access (web, skype,…)
The thing is that I can't event connect to this network… it says "Airport has an auto-assigned IP address 169.254.143.75 and won't be able to connect to the internet" (my computer is in french so my translation may vary from the english message). This occurs with Automatic DHCP for IPv4, and whether IPv6 is in Automatic or in Disabled setting.
The exact same thing happens whan I connect to the network using the Ethernet cable... I get the auto-assigned IP address and all...
Of course, I tried disabling and enabling Airport, and renewing the DHCP, but I always get this auto-assigned IP address.
I know the problem doesn't come from the hardware because I can connect without any problem to my wireless network at home.
I am using the 10.6.2 version of Mac OS and I already checked that all the available updates are installed.
I had a similar problem before upgrading to Snow Leopard : I could connect once to this open network, but then if I closed the lid of the computer, and then reopen it after a while, it wouldn't connect and I had to restart it entirely...
One of my friends has a Mac running with Leopard, and he has no problem connecting to the network, and neither do the windows user. I don't think it's a problem with the number of connections available on the network because I can NEVER connect to it…
Please help me!!! I'm hoping a Mac genius pops out of the computer and tells me what to doBonjour
The weirdest thing is that wired ethernet is not working, not getting an IP address. This may be some kind f incompatibility with the hardware but I doubt it.
Did you check in Airport and Ethernet settings that 802.1X is not enabled and that Ethernet negociation is "Automatiquement".
Also, you can completely wipe network profiles by removing those files from /Library/Preferences/SystemConfiguration/ :
NetworkInterfaces.plist
com.apple.network.identification.plist
com.apple.airport.preferences.plist
Then reboot -
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... -

Yet another iPhone WiFi thread - cannot connect to some OPEN networks
I make no apologies in starting another thread about iPhone WiFi connectivity. Judging by the number of references to WiFi issues in this forum, as well as on the Internet generally, this is a big issue with many users and yet there seems very little acknowledgement by Apple that there is problem.
In my case I have a first generation iPhone which works well on most WiFi networks, both open and closed, including my secured network at home, but cannot connect properly with some open networks. I have had this problem while using 1.0, 2.0 and 2.1 firmware.
Sometimes I get the "Cannot Connect ..." message and sometimes I am able to connect and obtain a good signal and see an IP Address and a Subnet mask, but no Router or DNS address.
I'll repeat that I talking about open networks, so there is no password issue. In one local cafe, I am unable to connect to a network that I used to be able to connect to routinely. I have talked to the owner, who is another Mac and iPhone user and he assures me that he has not changed any router settings.
Can anyone offer any suggestions beyond the usual re-setting and re-booting options? Is there something about iPhone MAC addresses or the WiFi signal that certain routers don't like?
SimonThis is not a solution to your problems but:
1- Expecting someone from Apple to respond here is a vain hope. This is a discussion forum for users and you can only expect responses from users. Talk to Apple tech support if you want a response from them.
2- I saw an item on an iPhone blog page somewhere yesterday saying that Apple was now replacing iPhones with this issue if you took it to an Apple store. Don't know if it's true but it also had a workaround that you could use for your own home network if you were having problems—and I am—and that workaround basically worked for me.
I turned wi-fi off on the phone and opened Airport Utility on my iMac. I turned wi-fi security OFF and then tried to connect. I actually got a connection straight away, and I noted down the IP addresses and subnet mask data from the DHCP screen in the iPhone's wi-fi network info screen. I then restored wi-fi security on my iMac. Of course that restarts the router and I lost my connection and when it started up again, the IP addresses had changed but the subnet mask had not. I swapped to the Static screen instead of the DHCP screen and edited all 3 IP addresses. That got me my connection back and it has continued to work throughout today. That's the best result I've had so far.
It seems to me that my iPhone has problems picking up the network data from my home network and I don't know why that is. I was at a friend's last night and tried to connect to his system and it connected straight away. I assume there's something about my settings which is problematic but I don't know what it is but at least now I have a workaround.
It's possible that something similar is going on for you with the public networks you're having problems with but, unfortunately, the workaround I tried won't work for you in a public network so that's probably not much help.
You could try taking your phone to an Apple Store and seeing if they exchange it. The blog I read suggested the magic words were "hardware problem". In my case I don't think it's a hardware problem but it may be in yours. -
MB not discovering/being discovered on Mac/PC network
Running a Laptop dual boot Mac OSX and Vista 32bit. (LT1)
Running a PC with Server 2008 installed (PC1)
When I open "network" on PC1 the Mac Laptop does not show, if i type in its IP address on the LAN 192.168.1.30 it prompts me for my login name and password and it can be browsed without issue.
On LT1 when running OSX the laptop does not see the server on the network, and must connect to it using Finder>Go>Connect to Server.. type in the servers IP and connect.
When at a friends house who runs Vista 64bit he can see all of his mac machines on his network; and my laptop shows up although under the laptops NetBIOS name "MAC001B63AD6F76"
When running the Vista 32 partition on the Laptop no problems exist.I use everything you are dealing with except 10.4.9. I stayed in 10.4.8 on both Server and Clients till all issues where resolved.
As far as error 519 (network communication failed), this is 9 out of 10 time a client issue and has nothing to do with the Retrospect Server unit.
Please go back to your post in the EMC Forums I posted more info there since thats realy where it belongs. (even thought by you coming here made me go there, lol)

AirPort with many closed/open networks.
There seemes to be a bug with the available networks listing in AirPort.
It lists all networks it can see, but fails to include information about wether or not these are open or closed/protected.
Thus if you find yourself somewhere with a gazillion WiFi networks, of whom most are locked, you end up spending an eternity before finding the open one(s).
Does anyone know of a way around this?
A filter for only listing the open networks would be great.
A small status icon besides network names like they do in every other OS I ever saw would be ok.Ahh, I have Linux for that...
I have a couple Linux installs, but I don't/can't do much of what I need to do with them... not Net-centric here... don't even own a TV for that Matter, and since Music died long ago... not much to listen to anymore!
Let me get this straigh. Is it possible to use this device purely as a detector? That is, just plug it in to find the names of open networks, and then log on with the AirPort?
Don't even need to plug it in to find Networks and any encryption they use, it has it's own LCD read out... just need to plug it in to a USB port once in awhile to charge it up! Use it disconnected if you like to find and enumerate any network within range... back to the Mac and connect to the open one(s) it shows, or have it hooked up to the Mac, (works with a USB extension cable for even more usefulness, (has better range/speed than any of my Apple cards... no n cards here though)
Alternatively, plug it in, switch networks, find networks, then switch back?
Yes, or not switch back and use it to connect... it & it's APP give far more info/options than the built in one! Yet you could switch back to a Location with Airport only enabled and connect to whatever!
(I have had 2 or more Wireless connections enabled at once, but it's best to have different Locations with just one enabled... can't tell you the exact steps to have/get 2 Wireless going at once, though it is possible, yet a whole lot easier/simpler to just have one enabled per Location).
I'm amazed at how many apps "call home" at startup / whenever they feel like it..
Thanks for the tip about Little Snitch... I've tried it, but I found there are a few APPs that work around it somehow, several Apple ones too!
Every day that goes by seems that there is something new in the works to take control of MY computer away from me, I only trust MS less than Apple on this issue... George Orwell is rolling over in his grave I tell ya... covered that iSight with tape yet that can be controlled by sites you visit? -

My G4 iBook refuses to see my wifi network I have here in my house. My Mac Mini, windows laptop and Nintendo DS all see the access point at various points throughout the house.
My iBook on the other hand is blind to it even a meter from the router, I have tried to create a manual connection and done a mac stumbler search but nothing. My iBook can pickup my neighbors networks in certain areas though and has been fine migrating across networks in uni.
Any suggestions ?Hi Kevin,
I assume your router broadcasts the SSID.
Open Network Preferences>Airport and enter the networks name there.

WRVS4400N randomly started broadcasting default open network!!
Seriously, can someone riddle me this.
Ever since acquiring this device, I have enabled a single wireless network, not broadcasting a SSID, and locked down with WPA2-Personal security. I've assumed all has been well for the past few months, and connecting to the network on a variety of wireless devices has certainly given me no cause for concern.
All that has just changed. On an Android 2.2. device which has been configured previously to join the network, I noticed that I could no longer connect. Amongst the various broadcasting SSIDs picked up on the device was an open network called "ciscosb". Thinking that an open network was pretty weird in this neck of the woods, I proceeced to connect to it, at which point I realised that "ciscosb" was the default SSID for this model of router and its hardware address indicated this was my very own router.
I checked and triple checked in the router's admin interface, and my original secure network was the only network configured.
I disabled and renabled wireless on the router, and what do you know, "ciscosb" disappeared, and I could connect to my original network fine.
So, while I'm resetting passwords for just about everything and before going on a rant to potential customers about why they should avoid this product for life, anyone have any ideas?
Firmware version:V2.0.1.3-ETSI for what it's worth.i've just checked my network settings and found:
Wireless LAN
Wireless IP Address:
192.168.1.2
MAC Address:
00:1C:XX:XX:XX
Network Mode:
B/G/N-Mixed
Wireless SSID:
ciscosb
Channel Bandwidth:
20MHz
Wireless Channel:
6- 2.437 GHz
Security:
Disabled
SSID Broadcast:
Enabled
But it's still broadcasting a different SSID (and no ciscosb), with encryption enabled and different channel bandwith.
The router has been up since about 59 days, with firmware-version V2.0.1.3-ETSI.
It's also "lost" the WAN, LAN, DHCP, ... settings, but is still using the previous set-up values.
cheers

I am an IT Manager at a hotel. We offer free wireless internet access to all guests. It is a completely open network. All PC users connect fine, as do the vast majority of Apple users. But about once a week, we get someone with a Macbook that can't connect. Their wireless settings show our network as being blocked. Occasionally we can get around it by manually adding a wireless network with the same SSID as our network and specifying it as open. Then the computer will connect fine. But this solution isn't easy when either I am not here and it is our front desk staff trying to explain this, or if the guest isn't very computer literate. It is also just plain frustrating for the guests. I would like to find a solution, so any help would be appreciated.
From what I gather from your first post, not every Macbook in your hotel is having this problem, which leads me to believe that the Macbooks that are experiencing this issue might not be up to date with the latest version of OS X.
In order to resolve this issue, you may have to do some detective work. If you run into this situation again, I would suggest that you ask the guest about what version of OS X he/she has installed on their Macbook. If they are having this issue, then they probably don't have the latest and greatest version of OS X, which is 10.6.7. If they are not up to date, tell them to download and install the 10.6.7 combo update, which Includes all the improvements in the previous Mac OS X v10.6.1, 10.6.2, 10.6.3, 10.6.4, 10.6.5, and 10.6.6 updates.
For instance, OS X 10.6.3 addressed:
AirPort and wireless networking fixes for:
* general reliability for wireless connections.
* improvements to 802.1X reliability, including closed network connections, and WPA2.
10.6.7 address issues in the AirPort driver for certain devices.
Of course, you would still have to help them get connected to your network first with your manual method so they could go online and download the combo update. Or, you could download the combo update yourself, burn it to DVD and hand it to your guest who is having the problem with their Mac. Talk about customer service!
I'm betting that combo updating to the latest version of the OS will resolve the problem. If not, well, I tried! Best of luck!
