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?

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 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 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.

Conflicting EAPOL-Key timeout needs
Our wireless setup is a single 7510 controller. I'm dealing with an issue where the Cisco 7925G wireless phone deployment guide recommends a 400 ms EAPOL-Key timeout (what we are using and phones work fine), but our Motorola/Symbol MC9000 series scanners seem to need more like 2000 ms to prevent issues (based on research, not actual testing). Our voice network is WPA2-PSK and the scanner network is WPA-PSK. The problem is that the EAPOL-Key timeout is a global setting on the controller affecting all WLANs. I plan to change the timeout to 2000ms this week and see what happens, but I wanted to see if anyone else has dealt with this and has any thoughts (like the phones will break if I change to 2000 ms).

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?

Re: [WIRELESS-LAN] Handheld scanners

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.

Re: [WIRELESS-LAN] locating stolen laptop - wireless campus network

This subject has been already addressed on Educause in 2008: http://listserv.educause.edu/cgi-bin/wa.exe?A2=ind0812&L=WIRELESS-LAN&T=0&F=&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] 4G Router Recommendations
We've looked at Cisco routers that support 4G cards, but haven't had good success in testing those. Verizon sent us to look at: http://www.cradlepoint.com/ This would just give you an Ethernet hand-off to whatever router you wanted to use (and they can probably act as the router). One thing to watch is the MTU on your interfaces. The Cradlepoint just drops the connection if you use a higher MTU than the device/cell connection supports. If I remember right, setting the MTU on the Cradlepoint ethernet port also sets it on the cell interface (for the model we tested). Nathan Hay Network Engineer | NOC WinWholesale Inc.

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.

Wireless in a truck
We are looking into using a cell connected router to provide wireless inside a truck. Right now we are trying to figure out how to power all of it with a UPS, etc that can survive freezing temps and very hot temps that the inside of the truck will be subjected to. I know some of you have provided wireless inside buses for students and other applications. Any thoughts on how to handle the varied environment?

Building map creation company?
Does anyone know of a company that will visit buildings and create drawings of them? Not a wireless site survey, just floor plan creation so someone else can do wireless layouts using the generated floor plans. Deliverables would include floor-by-floor maps at a minimum and possibly pictures or a video walk-through. This is not an invitation for companies to contact me.
