RE: [WIRELESS-LAN] WAPS seem to die after switch reboot
Are these 1131's LWAPP from the factory or did you convert these in the field from autonomous to LWAPP / CAPWAP? We have found that some of our converted 1230 series APs do this and show the same IEEE PD message on the switch. We had to go onsite or bring them back to the office to reload the autonomous image, convert it back to LWAPP, connect it to a controller and let them download the CAPWAP software version again. This would fix our issue which seemed to be a corrupted image. For the most part every failed AP image was preceded by some power event such as a power outage. -Jimmy James Helzerman Wireless Network Engineer University of Michigan ITS Communications Systems and Data Centers 4251 Plymouth Road, Building 2, #2224 Ann Arbor, Michigan 48105 Phone: 734-615-9541 Cell: 734-972-5095 -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Vikki Cutrone Sent: Wednesday, January 11, 2012 4:06 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] WAPS seem to die after switch reboot Got it, just did it per port-- same thing On 1/11/2012 3:51 PM, Lee H Badman wrote: For clarity- the power commands I referenced are port by port, not global. -Lee -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Vikki Cutrone Sent: Wednesday, January 11, 2012 3:50 PM To:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] WAPS seem to die after switch reboot Hi, They are down/down never to come on line again.

RE: [WIRELESS-LAN] Playstation 3's
We found a similar problem with the Blackberry Torch awhile ago on 7.0.98.0 and load balancing. Essentially with aggressive load balancing between APs turned on, clients that passively scan have a hard time connecting. I am not sure if the PS3 actively or passively scans for wireless networks or if any of the PS3 firmware has changed. Here is a link to the bug id and code versions that fix the passive scan problem. It might be worth checking out in the lab to see if it helps. https://supportforums.cisco.com/thread/2091932 -Jimmy James Helzerman Wireless Network Engineer University of Michigan ITS Communications Systems and Data Centers 4251 Plymouth Road, Building 2, #2224 Ann Arbor, Michigan 48105 Phone: 734-615-9541 Cell: 734-972-5095 From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Watters, John Sent: Tuesday, December 13, 2011 1:57 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Playstation 3's We have been running 7.0.98.0 since it came out with load balancing from the beginning.

RE: [WIRELESS-LAN] Problems in the Dorms
Hi. In the dorm areas with all the rogue APs do you leave RRM on? Have you tried freezing the configuration or setting channels manually for an area to see if the APs continue to reboot?

I have the WLC's setup with an equal number of AP's on each with Primary, Secondary and Tertiary controllers configured so I can upgrade one with them fail over to the others. I have spent the past 3 weeks pouring over the configurations on each WLC...even doing print screens of each to compare and they are completely identical. The WCS (running 7.0.172.0) has settings that the WLC's don't like (7.0.116.0) or are mismatched such as power level settings etc.So for those I just set on the WLC's and don't push out the templates on the WCS with the odd values. Here's our history: May 2010 we started with the 3 WS-C5508 and 1 WCS to handle all the dorms/academic/non academic buildings. We are a single campus (so no wan). We were running 6.0.199.0 on the WLC's (I believe) and there were a few problems. Cisco advised us to upgrade to 6.0.299.0 (maintenance release) to fix another issue, then 4 weeks ago upgraded to 7.0.116.0 to fix another problem. The WCS needed to be upgraded to 7.0.172.0 since the code we were running before wouldn't work with the 116.0 on the WLC's. /ugh Since the students moved back to campus we've had nothing but radios shutting off, AP's completely rebooting, AP's moving to secondary/tertiary controllers then back to the primary etc.It has been a NIGHTMARE. What I'm seeing is that our B/G channels 1,6,11 are also being used by the 450+ rogue AP's in the dorms. We can't shut off the B/G due to older machines, but the interference causes the A/N radios to drop as well. When we were running Autonomous AP's we didn't have this problem, but since moving to LWAPP we've had problems.

What we're seeing are the AP's either completely rebooting, radios shutting down then coming back up, or if the students are able to connect they get dropped after a few minutes. On the Academic side of the University we don't see this problem, however all the AP's are disassociating with the controllers every hour, then reassociating again. The WLC's are running 7.0.116.0 and the WCS is running 7.0.172.0. It appears that since upgrading the controllers to 7.0.116.0 the problems started with the disassociating/reassociating with no explanation.

RE: [WIRELESS-LAN] Wi-Fi connection issue when switching SSIDs
Hi. Do you have Fast SSID change enabled on your controllers? This setting is under Controller-- General. If it is not enabled, enable it and see if you performance improves. I was told by our SE on 7.0.98.0 code that this is to help with that issue. My understanding to it is the controller will cache the user for a small period of time to see if they come back on that SSID. Their MAC address is in limbo for this time and cant connect to any other SSIDs on that controller. When Fast SSID change is enabled this tells that controller not to stop that MAC address from connecting on any SSID.

RE: 1200 Series AP's on a newer 2960s Cisco switch using POE
The 1200 series (not 1240 series) uses the Cisco pre-standard power. The pre-standard power flipped the + and - wires. From the Cisco documents it should support Cisco pre-standard PoE automatically. Do you know if you are over your power budget for the switches power supply (blinking / alternating green and amber)? If it is blinking amber, have you tried a new cable (ie take the AP to the closet and plug it directly into the switch)? Have you tried to debug the PoE (http://cisco.biz/en/US/docs/switches/lan/catalyst2960/software/release/12.2_44_se/configuration/note/ol14988.pdf page 20)? If you have a 10/100/1000 Cisco 2960 you could also try setting the port speed from auto to 100Mb and see if that allows the 1200 to connect. -Jimmy James Helzerman Wireless Network Engineer University of Michigan ITS Communications Systems and Data Centers 4251 Plymouth Road, Building 2, #2224 Ann Arbor, Michigan 48105 Phone: 734-615-9541 Cell: 734-972-5095 From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Taillon II, Kendall Sent: Monday, August 15, 2011 2:57 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] 1200 Series AP's on a newer 2960s Cisco switch using POE We are in the middle of adding new 2960s Cisco switches to are edge.

RE: [WIRELESS-LAN] Wifi Support Staff
I also forgot to mention we have a field installation staff that does all the installs for networking equipment wiring including wireless access points. We always feel like we are behind a little bit in what we would like to accomplish especially testing and next generation stuff. Additional staff would help but I think we would end up in the same boat, taking on a bit more than we should at any one time. We definitely need staff to support wireless especially as it grows as the preferred main network medium (preferred by users not by us). To even think about replacing wired networking with wireless would mean a change in the wireless support model of reactive to proactive troubleshooting. This could involve a parallel sensor network to monitor RF in real-time and the need for quick response by our techs to correct any issues. This could be a topic in itself so I wont continue any farther. My point is the next direction you take your wireless networks in will almost mean you need dedicated and highly knowledgeable staff. We continue to deploy wireless based on customer requests. For the scale and timing that we are asked to deploy wireless networks I believe we are doing good. Most user complaints come from mis-configured devices or sources of interference and we are able to resolve them quickly. Unfortunately we have found that most users still do not bring issues to our attention and many go unresolved. We try to get the word out that we are here to help, so when I say we are doing good that is based on accomplishing our campus wireless directives and providing support to those that request it in a timely manner. -Jimmy James Helzerman Wireless Network Engineer University of Michigan ITS Communications Systems and Data Centers 4251 Plymouth Road, Building 2, #2224 Ann Arbor, Michigan 48105 Phone: 734-615-9541 Cell: 734-972-5095 -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of McCall, Melanie J.
