LCIN wired not working?

[Unregistered]

The wired internet is not working, its connected to the router but doesnt have internet connection. I am competent with computers so I have tried many things but it seems to be a problem on your end. All the cisco routers were flashing different colored rings, and just recently all went solid blue... and my laptop is recieving the UAWiFi signal again. However, I need my desktop wired connection working! I have no access to things so I cant fix this myself.

FYI: The internet (wired) was working flawlessly for a while, and aburptly halted (like someone pulled a cord somewhere) at about 8:30pm on 11/06/07.

If the wireless access points are cycling through the different colors it means that it is offline (either due to a malfunction or possibly an upgrade in-progress).

If you see green, it means the AP is on and ready to accept clients. Blue means it is on and people are connected to it.


My guess? It was a quick moment of downtime.

Thank you for that clarification.

However, why are the wired ports not working? Its been 3 hours or so now, dont the wired ports come from those wireless access points? Or is the wired internet in Pueblo de la Cienega coming from another router that I can observe?

Tried both wired connections in dorm room, don't work.

From what I have heard from people in the LaPaz lab, Vila Del Puente, Apache Santa Cruz, and LaPaz dorms are all experiencing the same problems. Heck I even had a network outage here in the OSCR LaPaz lab tonight from about 9:30 to 10:00pm. Everything seems to be back up and running now though.

darn, it isn't up here still (wired isn't, wireless is working).

Is there anyway I can restart or check something to get wired working in my dorm again?

thanks for assistance, glad its working for you again.

YES, I got it working... I dont know why it wouldnt work from restarting my computer... but the wired was working, tested it on my laptop... so that got me thinking that I was completely wrong about the situation.

I just went into the cmd window and typed

ipconfig /release
ipconfig /flushdns
ipconfig /renew

AND IT WORKED! Which is funny, because it didnt earlier when i did a release and renew... but that was probably because it was still down at that time.

sorry for my grammer, little tired

thanks for the help though

In the future, you can call 621-HELP for the CCIT Help Desk. They should be able to tell you if there is an outage or unscheduled downtime. Or, call 621-7999 for Network Operations -- but be warned that this is not a help desk number.

I had also ran a release, flush, and renew from a command prompt, this still did not provide for an internet connect, HOWEVER i was recieving an IP address and it was on the proper subnet. So this was some kind of downed connection on your part. And if you are running updates on your system WTF does them at 8:30 on a week night at a university. This is an operation that should have been done sunday at 2 in the morning. Ever heard of 99.999999% efficiency, certainly not after this, other outages, and the fact that your wireless internet setup is still flawed. O, and your help desk is a joke..

How is the wireless networked flawed?

peap certificates as it sounds do not work with Vista, therefore the connection is intermediate and drops about every 20min on the UAWiFi encrypted. Point being that your networks are not realiable. I do not wish to go through the trouble of using a vpn client to use the public. I just find it rediculous that as a organization of the university you can not proviide reliability for your students.

When you work in a wireless network environment on a Microsoft Windows Vista OS based computer, you may encounter several problems as follows:

a. You try to use computer authenticaion and user authentication to switch the client computer to different VLANs. However, the client computer does not obtain the correct IP address during VLAN switching. This problem is due to your IEEE 802.1X authentication that is based on Virtual Local Area Network (VLAN) switching may fail.

b. If different vendors provide more than one EAP method, the EAP method that is displayed in a wireless profile is not the EAP method that is actually selected. This is because in a wireless profile, the information about the Extensible Authentication Protocol (EAP) method that is selected in a user interface may be incorrect.

c. A wireless profile that an independent hardware vendor (IHV) provides may be corrupted after you use the wireless profile user interface to edit the profile. When this problem occurs, you may receive an error message that Windows Explorer has crashed.

d. Every time that you roam to a different wireless access point, you are prompted to provide a user credential. This problem occurs even if yo have saved the user credential.

e. You registered a Protected Extensible Authentication Protocol (PEAP) method that the IHV provided. When you try to authenticate against an Internet Authentication Service (IAS) server, the server may reject the authentication, and the IAS server may send an error message that the authentication has failed. The Onex.dll file crashes when this problem occurs.
The aforesaid wireless authentication and connectivity problems can be fixed with a supported hotfix (http://www.mydigitallife.info/2007/08/22/windows-vista-kb932063-hotfix-released-to-resolve-wireless-authentication-problems/#) from Microsoft. This KB932063 hotfix can be obtained from Microsoft Web site (http://support.microsoft.com/contactus/?ws=support).

You may want to give this a shot. This is the first I have heard that Vista having an issue with a Peap certificate, I know that Vista had issues and or lacked support for CCKM

The rule is generally "5 nines", or 99.999% uptime.

Wireless is inherently less reliable. If you want a fast and reliable connection, plug yourself in.


I think the university's network is pretty damn reliable given its complexity and size. UITS doesn't get much credit for things.

If you are still having an issue after trying the hotfix, feel free to give the OSCR Underground a call at 520-626-8324, and we can set you up with an appointment with one of the tech leads who can work with you to determine the cause of the problem with your system and attempt to fix it. If you do not wish to make an appointment, we do have walk-in hours on Tuesdays and Thursdays where a tech lead can help you on a first come first server basis. The OSCR Underground is located the Integrated Learning Center (ILC) room 136.

The help desk closes at 5pm, I did call them, this downtime was in the evening (like 8:30 or so).

I would say the wireless is pretty good here, I can get a signal at almost everywhere on campus. Just no more downtimes on the primetimes!

Use the NetOps number if it's outside normal business hours then.

We noticed an outage indicated in our wireless-stats log https://www.telcom.arizona.edu/wireless-stats/total.html on Tuesday night. We are still investigating. We also received calls that there was a problem with the wired jacks. Our network monitoring device did not show anything in the logs to indicate an outage https://www.telcom.arizona.edu/rovercgi/showrover

If you experience an outage after hours please report that to our NOC Network Operations Center
