Madwifi driver setup for WPA-PSK wireless encryption

Hi Group,
I thought I was so close to having a complete setup, but then a problem.
Here's the background:
Using archlinux with stock kernel 2.6.22 on IBM T21 or T23 Thinkpad.
Using an pcmcia SMC SMCWCBT-G network adapter.
I am using the latest 0.9.4 madwifi source tar.gz
The proper atheros madwifi drivers are installed and the ath0 device is active and functional.
Reading along in the madwifi docs, I found that I also had to install "Linux WPA Supplicant" in order to connect to a WPA secured router or access point.
I made the .config file as suggested in the Supplicant README and I set the defconfig file to work accept madwifi.
But when I try ~$/opt/wpa_supplicant-0.5.10/make I get the following errors and cannot figure what to do ---

Why the freebsd errors??
Any help or guidance greatly appreciated

Thanks for the reply, Iphitus.
I removed the source madwifi and wpa_supplicant installation and used pacman after the major update.
I setup the wireless to use netcfg2 command, but the connection still fails --
err, ath0: timed out
- DHCP IP lease attempt failed [FAIL]
I'm wondering if maybe I've overlooked something basic -- my access point is setup to use wpa2. does wpa_supplicant not work with wpa2?
I'll do some googling and see if I can find anything.
I appreciate your time and help.

WPA-PSK wireless not accepting password

For some reason I can't seem to connect to one in particular wireless internet router- It is using WPA-PSK security, and airport is telling me that I have an incorrect password although I am positive it is the correct one. I friend of mine determined that the router's security settings should be allowing me in, that it is most likely my computer that is the bad link- Please offer any suggestions!

I have the same problem.
I spent 2 hours talking with the apple support and the problem was not solved for WPA-PSK. The told me that they have a problem with many other people.
I have read a lot of forums and finally I found mend for Tiger that olso works in my Leopard. I change the password of my router to one in lower-case and it works. Yes! It is shoddy piece of work.
But in my university that I have WPA-PSK Enterprise don't works even if I change my authentication password to one in lower-case.

External hard drive setup for time machine reading as a virtual cd

Why is my MacBook Pro reading my external hard drive setup for time machine reading as a virtual cd?
Thanks

Hi Christian,
Is this something that has happened from the start? If so, I would reformat the disk and setup TM from scratch again.
Prepare the external HD by connecting to the Mac, open Disk Utility, select the manufacturer’s name of the external HD, select Partition and choose GUID Partition Table, format to Apple OS Extended (Journaled); quit Disk Utility.
Open System Preferences.
Click on Time Machine.
Click on “Select Disk.”
Click just to the left of "On" to turn TM on if it's not already on.
Click on the disk or partition you want to use.
Click on “Use for backup.”
Leave external HD connected, and TM will automatically do its thing.

Driver Setup for PXI 2569 and PXI 2529 in Switch executive

Hi,
What sould be tha "Driver Setup" for PXI 2569 and PXI 2529 in Switch executive under 'Driver Session"
Regards!!!
Vineet Shukla

Hi Vineet,
You do not need to insert anything under Driver Setup. Anytime you are using NI switches, you can simply click Configure NI Switches when creating a NI Switch Executive Virtual Device to configure the topology settings of those switches.
Just so you know, you can insert information under Driver Setup, and then you wouldn't have to use the Configure NI Switches wizard. More detail on what to insert under Driver Setup can be found in the following KnowledgeBase:
How Do I Create a Virtual Switch and Use it in my Application?
http://digital.ni.com/public.nsf/websearch/A1F0D6A3357E14B386256E4B0071FDA2?OpenDocument
In short, you would type "Topology:" followed by the topology name such as "2569/100-SPST" or "2529/2-Wire 4x32 Matrix".
Let me know if you have further questions or if this does not resolve your issue!

Found iPad 2 solution for WPA-PSK and WPA2-PSK

My security setting is WPA-PSK/WPA2-PSK on my modem/wirless router with Time Warner Cable. IPad does not have an option to select this security setting when attempting to connect to a WiFi network. I could connect my iPad by WiFi on some ocassions (selecting WPA or WEP on the iPad). However, I would lose connection after about 5-10 minutes. I have been having this problem for about 3 months. I spent a couple of hours on the phone yesterday with Time Warner and we think we "stumbled across" the fix (instead of actually knowing we found it). The tech noticed that the setup on the Time Warner modem/wireless router had the box for Active WPS checked. After the Time Warner tech unchecked Active WPS within the router's setup, the iPad starting picking up the WiFi signal. The iPad has now functioned for a full 24 hours without a problem or shutdown!
Please alert your techs and post this info on your website. When I talked with Apple techs in the past, they had no known solution to this situation and said that Apple simply did not support WPA-PSK or WPA2-PSK. The Time Warner tech also said that "he thinks" (but isn't sure) Apple's designation of WPA Enterprise equates to what others call the "old WPA" (or simply WPA) and what Apple calls WPA, others actually refer to as WPA-PSK (the newer WPA).

Hope you found a solution before now, but if not, try this:
Go into Settings, click on Wi-Fi and pick "Other" in the Network section.
Type your Network name in the name field (Caps do seem to matter), click on security and check WPA2.
Click the "Other Network" button to go back, input your password, click "Join".
You should now be good to go.

Hard Drive Setup for Creative Professional

Hi. I own a Mac Pro 3Ghz tower, and I only have one 250Gb hard drive along with an Iomega external 250Gb hard drive. I really need to upgrade my hard drives and create proper backups. I'm just not sure about the best options for backing up all my data and what the best options are for setting up my harddrives. Can anyone offer advice to a graphic designer that needs to upgrade his hard drive setup? I'm not sure what Raid is, so I would need to better understand what that does as well. I guess I need a road plan for the best way to go about all this upgrading.
Thanks.

Hi There,
I know you posted this more than a month ago, but i thought i'd see what you found and...what you can offer me in the way of answers. I appreciate any help you can give me!! Thanks in advance. I might have a couple options for you too.
I have the same set up pretty much. 1 250gb internal, 1 250 gb external, plus a 175gb external that i keep off site. Files are everywhere, yes i have copies, but it's an organizational disaster and not fail safe. If i lost a clients job, i'd loose more than the cost of just setting up a good backup system.
I found a few things out.
You can set up a software raid on your macpro using disk utility(although I don't know how to do it yet). (for raid info, look up raid on wikipedia, it's just a variety of ways to create more than one copy of data on any # of drives. 2 drives is a mirror image, 3 can be striped(any one drive can fail), and more...there are speed advantages with these too. )
Anyway i have 3 bays open for drives in my 2.66ghz quad. So setting up a software raid is option 1 - but from reading forums it seems like this isn't easy and requires maintainance? If you add a drive or remove one it erases all drives(?).
There is a system my friend turned me on to called Drobo.
It seems like the easiest solution and one that is lasting, check out the website at drobo.com it's external, has 4 bays and you can add and remove drives on a whim and upgrade up to 4tb. seems the easy solution, but costs 500 and then you need to purchase drives. but you can use any drives and it seems maintanance free.
Any recommendations - is software raid easier than I imagine?
Anyone have any offsite storage ideas? (.mac would be ideal, but it costs so much for storage and it's slow).
Looking forward to hearing your solution, and any advice for me.
Thanks,
Josh

Ideal drives setup for running Logic???

Hello,
I just purchased an internal 256GB Samsung 840 pro SSD drive. I have an external Firewire 800 2 TB external hard drive (7200 rpm) as well. What would be the ideal setup for running Logic?
Thanks!
2011 iMac 27", 16 GB of RAM, Logic Pro 9.1.8, OS X 10.7.5

Thanks.
Already talked to the tech doing the installation and he said I can stay on Lion.
Going to get rid of the optical drive, like you suggested, and keep the internal HDD to work in conjunction with the SSD. So, I'll put my OS X and Logic on the SSD, samples on the internal HDD, and project folders on the external firewire drive. Is this what you suggest? Did I miss anything?

Opinions sought: What is the optimal external hard drive setup for LP8?

I've got a MacBook Pro with only 10GB left on the HD after installation. I'm going to grab a nice big external Lacie 750 GB 7200RPM HD (via FireWire 800) solely for use with the Logic Studio suite. I have a few questions about optimal setup.
Option A: I leave the Logic programs on my MacBook Pro, and use the Lacie to record to.
Option B: I delete the Logic stuff from my MBP, and re-install all programs and content on the Lacie.
Option C: I install Mac OSX on the Lacie (making it bootable, I presume), circumvent my MacBook Pro's internal HD altogether, and run Logic from that.
Anybody? I'm particularly interested in hearing about what the issues are concerning latency and such.
Thanks in advance...
c.

Glad to see you chose "B"!
Just to clarify... I meant to say what Rohan suggested, i.e., apps on system drive, not on the Lacie.
Now, what's "content"? Well, it can be a lot of things...
• projects (including .bak song files)
• audio files
• sampler instruments and their samples (EXS)
• non-EXS sampler instruments and their samples
• apple loops
Three scenarios I'd suggest:
*OPTION 1*
Use your external drive for recording audio only. Store everything else on your system drive (sampler instruments/samples/apple loops, etc.). Also save your projects to your system drive. In this scenario your record path for audio would be your LaCie (create an audio folder specifically for each project). When you do routines saves of a project, leave the audio on the LaCie. Don't "move" them.
Thing is, you want to keep a certain amount of your HD space free and clear (I think the going figure is 20%) and this is for system use. It's important. But as you add more sample libraries as well as projects, you'll start to eat up your system HD space. But at least your audio recordings will be contained on a separate drive and not impinge on your HD space, keeping as much of it as free and clear as possible.
Anyway, if you go with this scenario, when you want to archive a project to another external HD or DVDs, you have a few choices:
a) do a re-save of the project to a new folder so that you've consolidated all of the material into one place, or...
b) do a re-save of the project to a new folder, include all sampler instruments & samples and everything else except audio; keep the audio in its own folder (just as it exists on the LaCie) and copy that to your archiving medium separately.
There are probably other strategies as well, but those are just two suggestions...
*OPTION 2*
Have TWO external drives: one for audio recording only, and another one for all other "content" (apple loops, samples, maybe even EXS sampler instruments, depending on how big your EXS library is). Store your projects on your system HD. With this scenario you keep your system HD very clear for system use.
I guess the main gist of the above two suggestions is that you dedicate your audio drive for audio. The less extraneous stuff on your audio drive, the higher your track count will be.
OPTION3
Same as above, having two external drives, but saving your projects to the second drive (not the audio drive). If your songs typically don't contain a ton of audio tracks, this should work fine.
Finally, a word about LaCie drives... I have three of them and have never had a problem. However, people who have reported problems with them are often quite vociferous in advising others to avoid them (and who could blame them?). So, just some perspective for ya.

Best Hard Drive Setup for Premiere Pro CS5.5

I'm running Premiere Pro cs5.5 on a Dell XPS 8300 (I know, I know!) with an i72600 chip and a 560TI card. The system came with two 500 GB Sata hard drives in a Raid0 configuration. I've seen a lot about proper hard drive setup but I'm a newbie (hence the Dell - I purchased before I read the forums). Should I add a third (or more) drive? How can I configure them taking into account what's already onboard? thanks very much!

If it were me, I'd add at least two more hard drives. A smallish one around 250 to 320 GB for the System drive. I'd reinstall Windows onto that.
Then I'd break out the RAID into separate drives, using one for Project and Scratch files and one for Exports.
The second new drive would be a really big one - 1TB or more. This I'd use exclusively for Media.*
* If I had a tapeless camera, such as AVCHD, then I'd definitely build in some kind of data safety, like at least a second 1TB drive for a RAID 1. Or if I had more money, add a third 1TB and a RAID controller card to make it a RAID 3.

Hard drive setup for CS5.5

Okay, finished a new build:
Intel Core i7 2600K processor
Asus P8Z68-V motherboard
Corsair 16 GB memory
Zotac GTX560 video card
OCZtech 60 GB SSD boot drive
2x Hitachi 1.5 TB 7200 hard drives
LG blu-ray burner
So the question is about the hard drive setup. Boot drive is pretty basic, with Windows 7 pro, CS5.5, firefox, and MS Office about the only things installed. So, two questions:
1. How do I change the boot drive so that things like "My Documents" is put on the D: or E: drive rather than the C boot drive? Is it a Windows thing or do changes need to be made within Office or Firefox?
2. How do I set up the two extra hard drives for Premier? The IT guy combined the two drives into one partition, which kindof defeats the point of having two drives, right? So we need to split those back out so there's a D & E drive and then I designate within Premier that the media cache and previews goes on one, and the storage & media & projects goes on the other? Do I need to do that within all the separate programs -- After Effects, Illustrator, Photoshop, Premier, etc. -- or can it be done all at once?
Thanks for any help!

1. Windows.
2. Those disks are in raid0 and appear as a single disk, so all you need is to have the IT guy add another two disks in a similar raid0 and to add an external disk for your backups.

Hard Drive Setup for Premiere Pro CS 6

I've recently made the switch from FCP 7 to Premiere and I'm trying to setup my hard drives. I've been reading up in the forums, but I'm still not sure on the best setup. I work with Canon DLSR footage 90% of the time. Here are the drives I've currenlty got it setup at below, but I'm willing to swtich it up to something better.
300GB WD 10,000 -- OS, Programs, Pagefile
2TB WD 10,000 RAID0 -- Media & Projects
2TB WD black 7200 -- Preview, Media Cache, Exports
2TB WD green -- Time Machine
Thanks in advance

Your drives and your drive setup both look pretty good to me. Possibly moving previews to your RAID could help. Realize too that fine tweaks at the level of performance you already have may help part of your workflow (i.e. timeline work) vs. other tasks (renders).

Wpa psk wireless connection on windows xp not possible

hi,
installing windows xp (incl. sp2) and the mac driver with bootcamp on my mac mini. my wireless router was found but it was not possible to use my required wpa password. only an wep-password was allowed. for security reasons i use a password with more than 25 signs.
what to do?
thanks, dieter

Setup for simple office wireless network.

I want to set up a small office networked environment.
I have a an Airport Extreme
Mac OS X Sever running on an iMac
A number of Macbook Pro's as client.
As I set this up, a quick - newbie - thought.
Do I set the server behind the airport extreme (connect wireless or wired? Does this make a difference) and have the Server assign IP addresses though DHCP the clients?
Or
Do I have the airport assign the IP addresses?
Any help or links you can send for me to do this setup myself would be much appreciated.
I keep getting error messages - my server name is "servername-imac.local" but when setting up iCal services iCal keeps trying to connect to "servername-imac.private"
I am wondering if this has to do with my setup?

I think part of my problem is also understand how to assign the IP addresses and having the airport assign a static address for the server?

Fastest hard drive setup- for creative professional

So with RAM upgrades being out of the question for the next month waiting for competition to drive down prices I turn to my hard disk situation in my new stock mac pro.
I am a creative professional with little to no interest in gaming. I am mearly looking to get the best performance out of final cut and the CS2 family of programs. So let me ask you all this.
With my one 250 gig drive, would this be a good general storage drive for say the OS, program files, music, and documents
While maybe setting up another drive as a scratch drive for photoshop and final cut? I have never setup a scratch disk or had the luxury of doing this. How would this help and how would I do it?
Also, how would raid 0 help me in this situation
Or maybe 10,000 RPM raptor drives, 16meg cache? Or simply 7200 fast enough.
I apologize for the lack of focus with this question, I am simply looking for the fastest setup with internal hard disks I can!
-Nicholas

First let me say my Raptors have been a RAID 0 for a few years now and they are solid drives compared to my dead Seagate and LaCie external (uses WD IDE drives, but it could have been the LaCie SATA interface)
Once they are properly Zeroed first in Disk Utility (before the RAID set) so the driver software doesn't play guinea pig with my data, they are very good drives. Enterprise level for sure. 24/7, quiet (at first they make slight clucking sounds) and fast as all heck.
Now to answer the original posters question.
RAM is the key to better CS2 performance up to about 3.6GB I believe, then after that I think the memory spills over to the "scratch disk" or boot drive. Now if your boot/scratch drive is a lumbering 500GB, then of course your scratch is going to be slow. With a scratch your trying to mimic the speed of RAM, so it has to be really fast. Like a stripe pair of Raptors for instance.
So having enough RAM to cover all your open apps and files, a GB for Mac OS X and you should be set. If your working on really huge Photoshop/Ampeture/Video files, then a stripe set of Raptors as a scratch/working disk with daily auto backup to a 500GB stock file drive is ideal.
A 150GB Raptor as a boot/app/itunes/bare bones "home" drive with files on another drive is the ideal setup. Mac OS X swaps memory, caches, grabs a iTunes song, small reads and writes to the boot drive all the time. A small, slim filled boot drive, below 50% filled, with fast rotation and access speed, is ideal. Less de-optimization because changing fles are kept off of it.
People notice a immediate difference in Mac OS X with a Raptor as a boot drive.
Note: Striping like mine doesn't give much more performance benefit as one Raptor is enough to speed up Mac OS X if bulky files are placed on another drive. I had stripe my 2 74GB Raptors because I needed more room and the 150GB didn't exist.

Setup for extending Sky wireless network using Airport Express or Time Cap

Hi,
Hi,
I have three Mac computers/laptops (iMac, MacBook Air and G4 PowerBook), all currently functioning via airport on a sky wireless network (Sky HD Sagem router) all backing up wirelessly to a Time Capsule 1TB which is also connected to the same wireless Sky network. At the top of my house signal strength is weak as you would expect. I would like to be able to extend the range of the sky routers signal which is on the ground floor (3 storey house). My original idea had been to setup a AirPort Express on the 2nd floor to extend the network, but I am unsure what steps I have to follow and whether I need to create a WDS network or not? I've seen some comments that say Sky & Apple hardware are not compatible and it's not possible to extend a Sky router/wireless network using a Apple Airport Express or Time Capsule. Can someone provide me with a step by step set of instructions on what I need to do to set this up? If a work around is required, again any advice would be very much appreciated!
Many thanks,
Eugene

Welcome to the discussions!
Sky and Apple products are not compatible for the purpose of extending your network using wireless only.
If you could connect an ethernet cable from your Sky router to the AirPort Express, or if it's not possible to run an ethernet cable...take a look at a pair of ethernet powerline adapters to accomplish the same task by using the AC wiring in your home to transmit the ethernet signal.
If you configure the AirPort Express to "create a wireless network", this would in effect, extend your network by adding an AirPort Express that would be configured with the exactly the same wireless network name, security settings and password as your Sky router. The AirPort Express would also need to be configured as a "bridge".
Post back if you need more details about something like this.
