Re: [WIRELESS-LAN] Ripley's Believe it or not, wireless edition
Wow I'm not sure what to even think of this. I had to read it twice just to be sure I understood it. I'll be honest, I haven't a clue and would be inclined to say I wouldn't have believed it! Do PS3's use the same MAC address for both wired and wireless I recall? Might be some clue in there somewhere. On Wed, Feb 26, 2014 at 11:28 AM, Turner, Ryan H rhtur...@email.unc.eduwrote: I am hard pressed to explain this. We've had a good number of reports of PS3s not being able to connect to wired or wireless in our residence halls. This corresponded to a pervasive wireless initiative that resulted in all new switches and Aruba access points installed for about 8,000 resident students. The PS3s would not show any wireless networks available, but more surprisingly, they would not establish a physical connection to switch ports, either. I brought a PS3 back to my office, and completely ignoring the wireless side, attempted to figure out what was happening to the wired side. I connected it, with success, to every type of switch I could find, new and old. I sent it back. We got more reports, and now I was forced to go into the field to look at the issue. I went to a dorm with a troubled unit, reset it, and configured it for a wired connection. It would not establish a link. Could it be a switch negotiation incompatibility issue? I turned off negotiation and manually set the config on both sides to no success. I then used an old hub that I knew would work to bridge the PS3 to our network. No link to the hub from the PS3. At this point, we took the same device and hub to a new location on campus. Booted up the PS3, with it ONLY connected to the hub (the hub wasn't connected to anything), and we got a physical link. I went into network settings to see if I could see wireless networks (I saw a good number). But then it dawned on me that we were in a significantly less dense wireless environment in the environment where the device was working. It should have no effect on the device since we were configured for wired, but I was grasping at straws. Was it possible that the density of Aps (and subsequent beacons) back at the original dorm was throwing the PS3 into a bad state caused the wired port to not work? So, we went back to the dorm, shut down ALL of the access points in the building that were near it, and then booted it up. LINKED FIRST TRY. It linked directly to the switch, and then indirectly through the hub. I started to power back on access points, and about halfway through, the physical link went away. We then reversed course, turned the Aps back off and rebooted the PS3 to verify it would get a link again. It did. I then turned all the Aps back on, to lose the PS3 link. We then rebooted the PS3 with all Aps back on, and it would not establish a link. There was no bridging occurring through the PS3 that would cause a spantree lock (verified). I am at a loss to explain this.

Re: [WIRELESS-LAN] WiFi planning
Also, coming in a bit late, but I am beginning to think the best method for my reshalls anyway is to put an AP in every other room, as they run linearly down a hallway. Then stagger the floor above to offset by one room. We've been doing every 3rd room lately and while it seems adequate, I think for density purposes, as well as signal level, moving to the every other room makes sense in the long run. As someone else mentioned, power output levels are one thing, antenna performance is another and then one still doesn't know anything about the device's' receive sensitivity which is another factor in the RF realm.

We are dealing with multiple areas in our dorms where AirMagnet Survey with the AirMagnet a/b/g/n card had a much better RSSI/SNR than the student with an iPad or iPhone has. What we should have done when surveying was to turn down the TX power to something like 25mW, which would more closely mimic a tablet or smartphone. We are in need of a survey tablet upgrade and currently looking at a Dell XPS with the built-in Intel® Dual Band Wireless-AC 7260 since that appears to have direct support within AirMagnet. But I'm considering also purchasing something like a Nexus 5 smartphone and using that along with the tablet to check RSSI. I would prefer to use an iPhone since that's what the majority of students have, but from what I can tell there's still no decent App that will give RSSI values. Curious what folks think of that strategy. Hopefully this is close enough to the main topic to not be considered hijacking. I had been meaning to get an email out on this topic.

Re: [WIRELESS-LAN] Wireless in Residence Halls
We've had them in the rooms, constant battle with the xbox syndrome, blinking lights, falling off the wall, etc... and since we had them in one in four rooms, coverage not so good to the others. We are now installing down the halls, about every 4 doors apart, or appr 60 feet. In the 2 halls I did last summer, not a single complaint. Since we are Aruba, I have contemplated the new 93H series APs but I still don't like the idea of one per room, in the room.

We've also made it clear that, if they are tampered with we'll turn off the service. This is the first term we've had them in the (few) rooms. It's been fine.

Our diagnostics have eliminated excessive loss in the cabling as the culprit, which seems to leave two possibilities. Either there are some Aruba AP-105s which are using more power than they are supposed to, or our switches are incorrectly measuring the power consumption of the APs.
