Macbook Pro wifi and application issues, everything slow

Hey guys,

So my macbook pro has been giving me a lot of issues lately. It doesn't appear to be one particular problem and it's spread out across applications. Here's my situation:

The wifi connection in my dorm room wont work all of a sudden. It's the schools wifi, so I can't mess with. But my roommate, who also has a macbook pro, is having no problems at all. So I think it's just my computer. It SAYS I'm connected to the internet and has full connection, but it doesn't go through.

Here's the weird thing... I CAN connect to any other wifi on campus just fine. And all ethernet ports work fine.

I'm also having trouble with a variety of applications. My Twitter app, mail wont load anything, Itunes store is slow or doesn't work, the App store wont open, Celtx.....

I think it's all programs that require some sort of internet connection to function. And it's really strange how all these applications still don't work right even when I DO have internet connection (through ethernet or other wifi).

Few notes: I've tried reseting the permissions, and I have 40GB free on my harddrive. It's been happening for a week now, and I've tried rebooting many times. I did a large software update right before it started happening, but I'm not sure if they are related.

What do you think? Is this something I can fix on my own? Or is something damaged on my computer?

HELP!

MacBook Pro, iOS 4

sounds like there is software or a plugin that is installed that is not playing nice with yoru current setup.

Dec 1, 2011 7:33 PM in response to TheSmokeMonster

Any suggestions? Anyway to possibly locate the app/plugin? I'll do a system update right now. See if that helps. Probably wont considering I already did it once.

Have you tried to install and run AppleJack?

Yes I did.

Okay, so the semester ended last December and I went home for Christmas break. No problems at home. Everything runs smoothly.

Today I moved back to school and all the same issues started happening again.

One thing I never mentioned in this before (because I thought it had nothing to do with it) is that my school started using a different WiFi system this past year. So this is most likely the issue. Something with the schools connection doesn't work well with my computer. This happens all around campus, not just my dorm.

Unless if ANYBODY has any suggestions, the next step would be to take my computer to the schools IT department. I'm looking for possible things to say or describe to them so that they have a better understanding about what is wrong with my computer.

Just to review:

Most applications that have some feature that uses Internet are broken or not working properly.

iTunes doesn't even open without crashing. (NEW)

Help!

Hi again,

Are you sure you don't have set your Internet connection to work through some kind of proxy, or that your U network isn't using one? If you have set your browser and email client (along with a few other apps that need to connect to the Web) to automatically detect proxy settings, and if said settings have changed, that would explain why you're having so much trouble connecting.

Jan 9, 2012 2:54 PM in response to FrenchToast

I checked my proxy settings in System Settings and they are all unchecked (open). Soo... is that good or bad?

Jan 10, 2012 9:51 AM in response to The Gryphonator

Let's say it's not so good... 😁

Could you take screenshots of your network settings and post them here?

Jan 10, 2012 1:31 PM in response to FrenchToast

I didn't know exactly what to take screenshots of. Hopefully this what you were looking for.

And when you that's "not so good" do you mean that this is most likely the problem? Or that we are still scratching heads?

I notice one strange thing in the second screenshot (#215): nothing shows under the "Configure IPV6: Automatically" field. There should be the router's IPV6 IP external/public address, then your own IPV6 address in the network, then a field called "Prefix length", probably indicating 64 (that's bits).

Try turning IPV6 off altogether, then reboot your Mac. Could be that your U's network has a problem coping with IPV6 addressing. A lot of enterprise and college network do, mostly because their servers don't actually have external IPV6 addresses, only IPV4, and extrapolating IPV6 addresses from them.

Jan 10, 2012 2:13 PM in response to FrenchToast

There is no option to turn off IPV6. I only get Automatic, Manually, and Link-Local Only. I CAN turn of IPV4, but that makes it so I don't get connection whatsover.

I have been battling I think the same issue. Seems the issue started when I upgraded Lion at some point and then only when I attempt to connect to a network powered or authenticated by the Aruba Networks authentication. Typically I have to rebuild permissions and a few other things that Onyx does to get Safari working again.Odd still, I can use my iPad on the same network without any trouble. I will likely be pushing the NOC at my job to work with Aruba to see if there are any known issues. I will let you know what I find out. But in the mean time, i would encourage you to talk to your help desk to see if there are any other reports. of issues. If you know of any other Mac users that are working, find out which version of OSX they are running. Good Luck.

So... I think I fixed the issue. I don't want to get too excited just in case if I'm wrong... but I think it's finally fixed.

I ended up finding someone at my school who had the same problem. They installed Lion and a lot of applications started to fail. Here's what he had me do:

I opened up my Keychain Access in Utlities.

I clicked on Preferences and went to Certificates.

I then turned both of them to OFF.

After that, I deleted the Wifi connection from my history and when I reconnected to the network I made it so I have to manually sign in every time. So after Sleeping or Shutting Down my computer I still have to click on the network and connect. Most people at my school have to sign in and put in their password everytime anyway. So I just have to click the wifi connection first and then do that.

Turning off the Keychain access definitely makes sense. (I think). One thing I may not have mentioned in this post was that I DO have to manually sign into the Wifi everytime I open my computer. This is something that I think all macs and pcs have to do at my school. (it stinks).

But I guess, maybe, all the applications that have some sort of Internet feature may have been doing this automatically? And perhaps that was causing all of them to crash?

Does this make sense? I'm trying to give all the details I can in case if anyone else has this problem.

Now... let's just pray this truly was the problem and that everything is fixed. We'll find out soon I guess...

If it is fixed... thanks to everyone who took the time to help with this issue. 🙂

good to hear.

Here is a response i got from my engineering department and Aruba:

The problem was caused by OCSP validation. Most of the latest browsers now support OCSP validation on ssl certificates. The problem occurs because the guest’s browser is trying to validate the ssl certificate on the Aruba Controller prior to authenticating through the captive portal. We had to create an acl for ocsp.usertrust.com (url in the default certificate) and allow http and https traffic to this url for all guests prior to captive portal authentication.

This is now reported to be working for at least one known impacted client in a hotel environment.

Seems that 10.7.3 has resolved the issues with the certificates and Aruba Networks.
