Hi,
I had the same problem with my tx2z and broadcom-wl. After reinstalling the wl and trying to enter the key as a string "key s:XXXXXXXXXX" I had a look at the key setup using iwlist:
[alpha@myhost ~]$ sudo iwlist eth0 key
eth0 4 key sizes : 40, 104, 256, 128bits
4 keys available :
[1]: off
[2]: off
[3]: off
[4]: off
Current Transmit Key: [1]
from there I decided to manually state the key rather than allowing implicit decleration. Hence writing:
[alpha@myhost ~]$ sudo iwconfig eth0 essid BTHomeHub-XXXX key [1] XXXXXXXXXX
rather than the error producing:
[alpha@myhost ~]$ sudo iwconfig eth0 essid BTHomeHub-XXXX key XXXXXXXXXX
This produced no errors and allowed the connection. Hope this helps, and sorry for lack of technical understanding (it were a bit of trial and error and have only recently started with arch).
Also, if it helps, my rc.conf section is as follows:
INTERFACES=(eth0)
and my ifconfig and iwconfig are:
[alpha@myhost ~]$ ifconfig

Bookmark this page, its the entry page to the Lenovo support pages for your 2374-Q39. In it you see you have the Intel 2200bg wireless card so this is the correct driver to use.

WEP and unable to set key?

I am by no means a Wifi expert but I do have a wireless router at home configured using 64 bit WEP. How do I input the key into my iPhone? It asks for a "Password" which is not apparently the same thing. If I try using "Other" and setting the security to WEP hex or ASCII it says it can't join. Does anyone have any ideas?
Thanks,
Michael

I have the same problem in that the iPhone will not connect to my Wireless internet. I can delete my SSID name and disable the password and still not connect (Unable to Join Network). I've used all the security connection options (WEP Password and WEP hex and ascii) on the security side. I don't even get a strength "fan" on the top of the display. My router shows no indication of any attempt to connect. My powerbook has connected using the WEP configuration.
I went to the Apple Store with my iPhone and had no problem connecting with their Wireless network (but they did not have a password requirement). My router shows no indication of any attempt to connect.

Timecapsual wireless connection unable to set up

I have a 1TB timecapsuale connected to my Mac with a cable. Everything works fine. I now want to connect the time capsuale with wireless instead of the cable and also use the timecapsuale as a repeater for my Router. Unfortunately I can't get this to work. Anyone who could point me into the right direction?

TC can only repeat another apple router. Is the other router Airport Extreme, Express or another TC.. if not, no it won't work.
You can use wireless.. Just setup TC to create a wireless network and set the airport in the computer to join to it.

Restore BOOTCAMP from .dmg image - Unable to scan (invalid argument)

I'm having trouble getting my maching back in order after a crash. I'm running a MacBook Pro 13" mid-2009 with a Bootcamp partition. Last week my harddrive crashed or something and I wasn't able to boot into either drive. Using the Snow Leopard install DVD and Disk Utility I made .dmgs of the entire HD and each of the partitions (Mac HD and Bootcamp - maybe overkill but..). I have since been able to restore my Mac side from the image, even without installing OSX - I just restored from the image using Disk Util again and everything seems to work fine. But, now I've been trying to do the same thing with my Bootcamp side - I have a separate .dmg for that. Everything seems to go fine except that when I try to restore it tells me the image needs to be scanned and when I scan I get the error message: "Unable to scan BOOTCAMP.dmg (invalid argument)". I've tried using different schemes of compression/ no compression on the image, tried to convert to a .cdr then rename to .iso and restore using Windows' native Recovery option. I even tried Terminal - sudo asr restore -noverify -source _________ -target __________ , but it wouldn't let me drag and drop in the Bootcamp drive icon...
Now I don't know what to do but ask.
Has anyone solved this problem????

Hi, and thanks for your reply.
Is there anyway I can convert my .dmg or .cdr/.iso to something that winclone can use?
ps I did finally get Disk Utility to scan the image. I had to convert it to a compressed .dmg from the uncompressed one and it finished it fine but still in Restore in Disk Util. I can't set the destination as my bootcamp partition.
Looks like I'll have to reinstall everything then eh? Well thanks for your help.

Problem connecting wirelessly from iMac to NETGEAR router, get invalid password message with WPA and WPA-2 encryption in place but if I remove them, so no security, can connect without a problem. Help!!

Problem connecting wirelessly from iMac to NETGEAR router, get invalid password message with WPA and WPA-2 encryption in place but if I remove them, so no security, can connect without a problem. Help!!

Thank you for your suggestion but I have already had a couple of phone sessions with NETGEAR support and they don't see any problems with the router settings etc. They referred me to Apple support, who helped me discover that it is possible to communicate with the router but only if I turn off the encryption/security software, which I don't want to do. The frustrating thing is that I can connect wirelessly from a laptop running Windows 7 and two Anroid smart phones, with WPA-2 in place, without a problem. Do you have any other ideas?

[SOLVED] sudo: unable to set runas group vector: Invalid argument

I recently made the (idiotic) mistake of overwriting my /etc/passwd and /etc/group files, although I managed to restore them from a backup. Since restarting the machine I'm having the same issue every time I invoke sudo:
sudo: unable to set runas group vector: Invalid argument
I can't find any info on this error. Any ideas on where to start?
Thanks,
-- C. M.
EDIT: I should also note that this is a headless machine that I'm accessing via SSH.

Thanks for the reply, Amish.
It's my understanding that the 'group vector' is a term that refers to the specific set of groups to which a user has membership, rather than a specific group named 'vector'. Although, I could be mistaken.
From the sudo manpage:
The -P (preserve group vector) option causes sudo to preserve the user's group vector unaltered. By default, sudo will initialize the group vector to the list of groups the target user is in. The real and effective group IDs, however, are still set to match the target user.
Similarly, from the sudoers manpage:
By default, sudo will initialize the group vector to the list of groups the target user is in. When preserve_groups is set, the user's existing group vector is left unaltered. The real and effective group IDs, however, are still set to match the target user. This flag is off by default.
But the manpages don't offer me much, I'm still clueless as to why I'm getting the error.
EDIT: although using the -P flag seems to allow sudo to run without error

Illustrator CS4 problem loading: unable to set max files...

Haven't opened AI CS4 in a few months. Used to load just fine. Today it crashes when loading and I get this error message: 'Unable to set maximum number of files to be opened.' I'm running OS 10.4.11 on a MacBook. The rest of the CS4 suite opens just fine. I have already removed the preference file for Illustrator out of the user library and also removed the 'com.adobe.illustrator.plist' file. Restarted computer. Still can't open the program.

Printer suddenly unable to connect to network (invalid password)

I've had this printer for half a year and haven't had any issues with network connection till recently. For some reason my printer will no longer connect to our network. I've typed in the correct password multiple times but it always comes up with an invalid WPA passphrase.
My laptop and other devices have no problems connecting to the internet. The printer recognizes the wireless network but says the passphrase is "invalid". I printed the diagnostic and it says, "The WPA security passphrase configured on your HP printer does not match your wireless router setting". The solution they gave was "Run the wirless Setup Wizard to re-enter your wireless network WPA security passphrase."
The solution does not help.
Some of the results from the printed diagnostic test:
Connectivity> connected = Not Run
Disconnect count total= 70
Network> Network SSID Found= PASS
Settings> Printer settings consistent with wireless router settings, no filtering, channel = Not Run / Security = FAIL
Current Configuration> Authentication Type = WPA- PSK / Encryption= Automatic (AES or TKIP)
We are running on a 802.11 network, channel 11 (I don't really know what this means..but maybe it's helpful information?)
If anyone has some insights that would be greatly appreciated!!

My printer mysteriously started working again as well. Nothing has changed on my equipment. What gives?
As for the "Great" support from HP with the Static IP address, I don't see any replies from HP on this thread helping us out.

Unable to set Guest Network

I have set up a Wifi Network using one Apple Airport Extreme.
While me regular WiFi network is hidden and working fine, I am unable to set up the guest network.
I have enabled the guest network option with a password. under the wireless tab in airport utility
My internet connection is using DHCP.
The Router Mode in Network is OFF (Bridge Mode)

The Router Mode in Network is OFF (Bridge Mode)
That.....is one of your problems, since the Guest Network option will not operate correctly when the AirPort Extreme is configured to operate in Bridge Mode.
The other problem that you have.....is that Bridge Mode is actually the correct setting for the AirPort Extreme when you have another router "upstream" on your network......as you do.
To confirm that you have a modem/router or gateway device on your network........and not a simple modem, which is the device that you really need to enable the Guest Network to operate correctly.....please post back with the make and model number of your existing modem/router or gateway device that is providing your regular Wi-Fi network at the present time.

Unable to set the ip address for hosted network client after creating WIFI hotspot

Original Title: INTERNET CONNECTIVITY PROBLEM WITH MY LAPTOP WIFI HOTSPOT
HI all
I am able to use internet connection from my lap hotspot, when the internet source is Public or private wifi.
so I know the cmd window commands for hotspot and settings of client(sharing to hosted network client, assigning IP address etc.,)
but the problem I am facing is slight different
I am using my cdma wireless broadband datacard as my source internet connection(Reliance netconnect +)
when I try to create hotspot for this, as usual I am able to create the hotspot and able to share the internet to hostednework client.
but I am unable to set the ip address for hosted network client, if I try to set ip 192.169.137.1 and 255.255.255.0
as soon as I close the window, the ip address also disappears
when connect my android phone to that hotspot, it is able to connect but there is no internet connectivity.
when I check the hostednetwork client for packet transmission, both sent and received packet is happening., I mean transmitting
so what cause the failure in internet connectivity but success in hotspot connectivity?
check the screen shots...
can u help me..
its little complicated

Hi,
Please make sure the Ad hoc connection IP adress is at the same range with your local connection. In addition, how about recreate the ad hoc connection for test, please have a try.
If problem persists, please use Network troubleshooter in Action Center to fix this problem for test.

Unable to set safari in full-screen mode

Hi folks,
I just factory reset my 15-inch MBP running 10.9.3. After doing so, I notice that I am unable to set Safari in full-screen mode. Any ideas??

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.
