Apple devices and dual-band SSIDs
We broadcast our primary SSID in 2.4 and 5 Ghz, but Apple devices seem to hop back and forth, causing disconnects for users. I am contemplating make a 2.4 only SSID and 5 only SSID, but I want to balance this it with not confusing the users. How have others dealt with this? We are running on a Cisco 7510 with code 7.4.100.60. APs are 1042 and 1602 all operating in FlexConnect mode.

Re: [WIRELESS-LAN] Typical new AP failure rates?
In a batch of 500 Cisco APs of the same model purchased at the same time, I have had no DOA and maybe 3-4 failures (less than 1%) over the past 16 months. All the failures have been in the same manner, so I think there is a small defect in the AP. Nathan Hay Network Engineer | NOC WinWholesale Inc. 888-225-5947 From: Steve Bohrer skboh...@simons-rock.edu To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU, Date: 01/30/2014 10:49 PM Subject:[WIRELESS-LAN] Typical new AP failure rates? Sent by:The EDUCAUSE Wireless Issues Constituent Group Listserv WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Is ~2% early failures in a batch of APs typical, or should I be concerned about a manufacturing defect or some unknown external factor? We're small enough that we've never before bought more than 15 or 20 new APs at once, so haven't previously had any early failures. However, we've just upgraded our full wifi system, and I have two dead out of 105 APs after a couple weeks. Not DOA, but they ran each ran for several days, and then went of line. They're obviously still under warranty, so all I can do is wait and see how widespread this problem will be, but I'm not sure how much to worry! Hopefully after failures during initial burn-in, the rest of the APs will all last a long time. A few basic Google attempts didn't yield stats for initial and longer-term enterprise AP failure rates, so I'm curious about what you bigger schools experience, and how much variation there is by model and vendor. Are 3x3 and ac radios more failure prone than simpler, perhaps cooler running, gear? I generally expect some APs to fail every once in a while, but as far as I know, no vendor has a reputation of being much better or worse than the rest. If those of you who've been buying thousands of APs for years have data you can share, we may get at least an anecdotal feel for typical failure rates, and perhaps a sense of variation by vendor and product.

Re: [WIRELESS-LAN] WiFi planning

Multi-tenant wireless question
We have an interesting design problem that I thought I would toss out for ideas. Using 1042 and 1602 APs with a single 7510 controller. We have two of our companies sharing building space (the spaces are inter-mingled, not separate suites), however they have separate routers and ISPs and they are not routed between each other back at our core. I can cover the space with 3 wireless access points, but I need to have different SSIDs and keep their wireless completely separate, connected back to each companies respective routers. My current best option is to deploy 6 APs (3 for each) and use RF profiles to keep them from turning their power down too low since each pair will be 10 feet apart or so. This also costs me twice as much. Another option we are tossing around is connecting a cable between the two router/switch setups to allow us to map the SSIDs to a VLAN on each router. This causes future support issues though and if this connecting cable is every moved (very likely to happen) it could cause issues. Also, all the authentication/management traffic would go out one of the routers, so if that one goes down, the other company loses their wireless as well. Anyone have any creative ideas?

File copy problems over wireless from Macs
We have a problem that only shows up every couple of weeks. Some of our developers with Macs (specifically an Air, fully updated) cannot do file transfers from their Macs to their servers such as HTTP PUT, FTP, SCP, SFTP. They never lose their wireless connection, but these transfers fail. Everything else works. I have not been able to reproduce the issue on a Windows box. Plugging in fixes their issues, but not all of them can plug depending on where they are working. We are running a Cisco 7510 controller on 7.3.101.0 code. They may be connected to a 3502 or 2602 AP at any given time. All our APs are in FlexConnect mode. None of the developers will let me capture traffic on/from their Macs, so this is all I've got. I'm going to try to get my hands on a test mac sometime, but I wanted to see if this sounds familiar to anyone. Thanks for any thoughts you may have.

Re: [WIRELESS-LAN] locating stolen laptop - wireless campus network
One trick I used to use is to watch the traffic from that IP address to see if the user gives away their identity by logging into a campus system (email, web filtering, grades, etc).

This subject has been already addressed on Educause in 2008: http://listserv.educause.edu/cgi-bin/wa.exe?A2=ind0812L=WIRELESS-LANT=0F=S=P=37407 and in 2010: http://seclists.org/educause/2010/q3/176 I am wondering if progress was made on this topic in the last years. In particular, I wonder how to precisely locate a stolen device, after you get the alert that its MAC address is detected on the network (the laptop appears associated to a specific AP in a specific building). How can you pinpoint that device? One option, is to walk around with a laptop and an AirPcap card, sniffing the traffic, filtering on that certain MAC address and when the RSSI gets higher it means you are closer to that stolen laptop. However, this is not that discreet and there’s always the risk that before being able to pinpoint the laptop, the fake owner will leave. Another option is to use tcpdump on a laptop, and filter the raw packets from that MAC address and constantly monitoring its signal level until the best value is found. Airodump, which shows the traffic on all channels is also an alternative. Is there a complex and more user friendly tool that is being used in your campus? ideally, a tool simple enough so it could be used by the security staff (the persons entitled to catch the thief) on a tablet or smartphone? Any experience/thought/recommendation on this subject would be highly appreciated.

Re: [WIRELESS-LAN] WiFi/Leaky Coax

Wireless clients cannot connect to each other
I'm working on a fairly new Cisco wireless install and we just discovered that (any) two wireless clients cannot find/ping/connect to each other when they are both on wireless. I'm working on a TAC case for this now, but I wanted to see if anyone has run into this. Here are some details of our setup. Flex 7510 controller running 7.3.101.0 APs are 1042 (most testing done here), 2602, 3502. APs are all in FlexConnect mode. Wireshark shows the clients arping and never getting a response to the ARP so it never finds the other client. Even with both clients on the same SSID/VLAN/AP. All connectivity to the wired network works fine. We have not yet verified how far the ARP gets on the network, but it seems to be a problem at the AP since two clients on the same AP can't ping each other. If one client goes wired, they can ping each other. We have broadcast forwarding enabled on the controller and P2P blocking action is disabled. Thanks for any thougts you may have.
