Issues with WiFi and Vista

September 18th, 2009

In my lab I keep a wireless access point active; mainly for students and profs using it to connect computer together for whatever. I used to use a WPA password for the system. WPA worked fine except that many people who were not supposed to be on the network were on there. Students would give the password out, and this annoyed me. That network is supposed to be for DM staff and students only, that’s why I have it separate from the schools wireless.

Over the summer I made a lot of changes to the network, mainly I changed it over to use WPA2 Enterprise with our RADIUS server. The logins are taken from our Open Directory LDAP (the ones people use to log into our machines, website, wiki, etc.) and thats how people connect. Works great in MacOS, I select the network, put my user and pass in and voila! Windows was another story.

My MBP has Windows 7 Ultimate; I was able to connect to the network after changing some WIndows defaults. It does ask for a login, which is better than what XP did, but it still had some issues. I had to disable the “Check server certificate against blah blah”, because it’s a self-signed cert it wouldn’t work. I also need to disable “Use windows login password to login to this network.” I understand most people using “enterprise” networks all use AD or whatever to login to their computer, but why make that default? Not to mention, to change both of these options it’s 5 levels down or so buried deep in the wireless preferences. It’s impossible to change if you don’t know what you’re doing.

Windows 7 connects fine now. No issues, it’s actually very stable. Issues arise when Vista users connect. Now, when I add the network for a Vista user it comes up as WPA2 Enterprise (good), AES (great), it even prompts for a user and password (excellent). No connection. I change those settings above again, because it’s by default, still nothing. I go into even more advances prefs by changing the authentication method to MSCHAPv2 or TTLS, PEAP, whatever works. Nothing works. I check all of the Vista prefs with my working Windows 7 prefs, they are identical. What is the issue then?

After a good Google search, and more and more searches, and stops to Apple discussions, and everything else I can think if, I see similar results. Apparently Windows Vista HOME does not work with WPA2 Enterprise. It just doesn’t work. It’s “broken” as some would put it, or “disabled.” Whatever the reason, my question is “Why??” Why do you put WPA2 Enterprise network prefs and even allow me to add said network to my computer when I can’t fucking connect to it? Explain that one, please! If you don’t want Home users to connect to enterprise networks, take the fucking thing out, don’t just make it act like it works and then not let it. How do I know it’s a client issue and not a server issue? Logs.

My server logs all RADIUS connections and attempts to authenticate. My server issues the challenge to the machine, but the machine apparently ignores it, or throws it away, or wipes its ass with it. It does NOTHING.

Now, I was having this issue with some other computers as well, Windows XP users. Their main issue was that they didn’t have updated drivers or settings were screwed up, but they eventually worked most of the time. I’ve also tried with some Vista Pro computers, and yes it works most of the time. The times it doesn’t usually work, I tell the people to get the software from their card manufacturer and use it, and then it seems to magically work.

What is wrong with WIndows wireless? You got me, but I finally told those people who couldn’t connect to either upgrade or deal with it and connect to a poly network. Hell, Poly’s putting N-Wireless in, I might just use it from now on also!

Computer Repair is ever complete without…

TESTING!

When I am given a computer to repair by a customer (or anyone to be exact!) I do my best to be quick with the job as well as do it RIGHT. I test everything about the computer that I changed/fixed/replaced. I do not want people bringing their computers back to me for the same issue, it doesn’t make sense for someone to have to bring their machine back after I just fixed it. Unless it’s something totally different.

Why am I writing about this now?

My MacBook Pro iSight seemed to stop working randomly one day. I tried to use it and it didn’t work. System profiler didn’t show it, something was wrong. I brought it to Tekserve first. They claimed that it was hardware but since I had a small dent on my computer (no joke) they wouldn’t cover the warranty because Apple would deny it. I found another place in the city which I was told would take laptops in almost any condition as long as the condition wasn’t the cause of the issue and repair it under Applecare. Sure enough they replaced my logic board and my iSight worked again. I got my computer back in 2 days time.

I get home I try to use my DVD drive and find it doesn’t work. System profiler acts weird saying it works sometimes….then it doesn’t….whatever. I open the laptop and re-seat the cable. It loads a DVD but when I start doing reading from the drive it loses it. Something is obviously broken. I take it back and explain to them the issue. They take it and call me 2 days later saying they cannot reproduce the issue and it seems to work fine. I say, well, if you say it’s working fine, I’ll come by to get it. I get my laptop home and sure enough, same issue. I bring it back the next day. They claim they put a DVD in it and it read it so they deemed it as fine. Really? You did exactly what I told you I did and didn’t think to read from the drive?

After a conversation I tell them to replace the drive ASAP; meaning get the part and call me when it comes in so you can install it right then and there because I’m tired of not having my laptop. They install it and tell me to come back because it’s fixed! GREAT! I go and ask “Do you have a disc I can boot from?” He hands me a Leopard install disc and sure enough the disc does not load at all. Mr. Tech then tells me “Oh you have a third-party boot software (rEFIt), it’s probably the issue. It wasn’t hardware, it was YOUR software.” I then need to explain to him that it was fine until they replaced my logic board. I also ask “did you replace the ribbon cable also?” to which I never get a straight answer for (No). The tech doesn’t believe me, so I uninstall rEFIt on the spot and boot. The disc gets loaded, oh my god! He then gets a smug look on his face and says “It was obviously the software, see it’s loading.” After waiting 15 minutes, it doesn’t load. This was about the time where I wanted to shove the guy’s face into a wall; he finally takes my advice and boots from an external drive, HIS DRIVE, and goes into system profiler. The drive is no where to be found. Thank you. Hardware failure.

Now, I am told that they need to send it to Apple for repair. Why? All you need to do is replace the god damn ribbon cable, and if that doesn’t work, the logic board is bad. It’s not difficult to diagnose!

So, after 4 trips to this place I lost my laptop for at least a week now all because the tech’s didn’t test the repair properly. If you install a new optical drive, or if a user says “something is wrong with my optical drive,” what should you do? Should you pop a disc in and say “Oh it showed up, it’s obviously not broken at all?”

NO!

You put in a disc, read from it, install something, burn a disc, ANYTHING THAT TESTS THE DRIVES OVERALL PERFORMANCE! NOT THE EJECT MECHANISM! NOT THE [does the disc load, software?] MECHANISM!

What have we all learned (except Digital Society apparently)? Test your repairs!
