Yeah, we are going to hopefully try that this afternoon.

Interesting. - We are also experiencing the same issue with PS3.   Turned off 
OTA and now the PS3 works.

Subject: [WIRELESS-LAN] Ripley's Believe it or not, wireless edition

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.
