We take a slightly different approach to what has already been shared when it 
comes to students. When students in either a residence hall or other campus 
building call in, our student employees on the phone collect the following:

·         Drivers (check for updates, ensure that correct drivers are installed)

·         Power Settings (ensure that maximum performance is chosen for battery 
and plugged in)

·         Delete/Re-Add Saved Wireless Networks

·         Disable Link-Layers

·         Disable Printer/File Sharing



If the issue can’t be resolved there, they send it on to our full-time helpdesk 
staff. We ensure that there’s not an obvious issue (major interference detected 
by the nearest WAP, WAP unplugged or otherwise not functioning as expected) 
with our access to Cisco Prime Infrastructure. We also look at the client in 
Cisco to see if they are connecting over 2.4 or 5GHz, etc. If there isn’t 
anything obvious, we then schedule an appointment with one of our student 
employees in the field. They have different training then our phones techs and 
regularly handle wireless network issues.



In the field, we ask our student techs to collect the following:



·         Document Client Info:

o    What is the student's primary band? (5.0GHz or 2.4GHz)

o    Record and label all device MAC addresses with limited connectivity.

·         AirCheck (for ResNet and for ResNet-Alt):

·         ResNet: Strongest 2.4GHz (g/n) AP dBm: SNR: AP Name/MAC address:

·         ResNet: Strongest 5GHz (a/n) AP dBm: SNR: AP Name/MAC address:

·         ResNet-Alt: Strongest 2.4GHz (g/n) AP dBm: SNR: AP Name/MAC address:

·         ResNet-Alt: Strongest 5GHz (a/n) AP dBm: SNR: AP Name/MAC address:

·         Does the Aircheck show varying dBm?

·         Does the Aircheck show non-802.11 interferers in the "Channels" menu?

·         Does the AirCheck show any rouge APs/Printers? (Include names of 
networks, channels, dBm)

·         On MacBook Air:

o    Check connection speed: <Link removed> 10MB file.

o    Time to download file:

o    Does the MacBook Air stay connected to the AP?

§  If not, how long does it stay connected?



Our techs use Netscout 
Airchecks<https://www.amazon.com/NETSCOUT-AIRCHECK-Display-Operating-Temperature/dp/B003JZ076U?sa-no-redirect=1>
 to collect much of this information.



Once we collect that information, the helpdesk full-time staff work with our 
network engineers for further solutions. Many times this involves a power level 
change, WAP relocation, or additional WAP being added. We are always the ones 
to communicate with the end-user.



This generally works well, as we’re able to filter out many client-side issues 
before they reach our network engineers. For more complicated issues, we may 
also coordinate to have a network engineer meet us in the field for additional 
troubleshooting or analysis.

Subject: [WIRELESS-LAN] Helpdesk Troubleshooting of Wireless Issues



I'm curious if people can share their delineation of duties between the support 
organization (help desk) and the network administration (engineering, etc) 
teams, especially as it surrounds the triaging and troubleshooting of wireless 
connectivity issues.



What is expected from the support organization before an issue is escalated? 
Who communicates with the end user? What tools, resources, and training are 
made available to techs? Are all support techs qualified, or just a "wifi 
strike team"? Lessons learned?



Thanks!
