Just fyi,
this was discussed on the resnet mailing list, same as Eric mentioned.

We recently disabled OTA updates and the feedback we've gotten from students
has been positive. It appears that was our issue. Thanks for the suggestions.
~~
We have seen this issue as well with some of the first generation PS3's.
Some of them we are able to update the code manually to the newest ps3 version
and they will start working. Then others when we updated they still do not
work. Still trying to figure out what the issue maybe.... Doesn't seem very
consistent.
best!

Once we disabled ARM OTA in the residence halls the older PS3 devices
were able to connect wired and wirelessly.
"The PS3 (CL917784871-CECH-L01) that we have been working with falls
under first generation and its version(s) are CECH-LXX, CECH-KXX and
CECH-MXX. WLAN NIC in older PS3s(First Generation) do not handle OTA
frames which will be "unrecognized frames" correctly.
Ideally, the PS3 should IGNORE these frames and carry on, but it
results in connection drop.
As it's a client inability at this point to handle such frames, we
have successfully worked around this issue by disabling OTA which
would be a potential fix as such for client side issue."

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.
