Re: PS3 dropping off the network

We had several of our users who were having the trouble and who were willing to perform the factory reset try but to no avail. We've had XBox users successfully fix their problems with a wipe but with this particualr PS3 problem it didn't help our users.

Re: PS3 dropping off the network

We run 93Hs in our res. halls, and I finally got an older model PS3 to test with and what I have noticed is the PS3 prefers wireless over wired, so at boot it will look for a wireless network to connect to effectively disabling the networking on the PS3 when being used in the res. halls.  In the lab setting, however, when I only have one 93H up the PS3 works fine, but as soon as I bring up a second the PS3 network gets confused or overwhelmed or something and from a few seconds to a couple of minutes the network on the PS3 shuts down and will not function.  Take that second 93H down and within a few minutes the PS3 is fine again.

Re: PS3 dropping off the network

This is the response from TAC and disabling the ARM OTA updates does solve our problem:

 

"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.

 

a) Under the ARM profile for 802.11a & 80211 g, please disable the option ARM Over the Air Updates & let me know if it resolves the issues being seen. 

 

Disabling ARM OTA updates will not have much of a negative impact as “PASSIVE SCANNING” would still work and will help AP's discover each other.

 

The ota-updates option allows an AP to get information about its RF environment from its neighbors, even the AP cannot scan. If this feature is enabled, when an AP on the network scans a foreign (non-home) channel, it sends other APs an Over-the-Air (OTA) update in an 802.11 management frame that contains information about the scanning AP's home channel, the current transmission EIRP value of its home channel, and one-hop neighbors seen by that AP. 

With that being said, When ARM OTA is enabled, the Aruba AP will send OTA updates that are Aruba proprietary packets which can only be interpreted by Aruba AP's and will be bogus frames for other clients or devices. 

802.11 Broadcast management frames will be processed by NICs but anything with subtype 15 should be dropped by most NICs. In order to understand why the older models of PS3 hang when they receive this subtype of management frame, it may be helpful to follow-up with Sony. We have not seen any other client devices behave this way. Also, it seems like something got fixed in the newer model of PS3's since the issue is not seen there. Do you have a case open with Sony by any chance? 

Some older PS3 models shut down their NIC when receiving OTA management frames form the AP. This seems to be client-specific issue."

Re: PS3 dropping off the network

I'm glad we have a response from Aruba on this finally, however what confounds me is that a year ago this was not a problem.  I'm sure we have quite a few of these on campus, and it's only been reported since the students returned this fall.  Is the "Over the Air Updates" a feature which has been added to the code base within the last years time frame?

Re: PS3 dropping off the network

I didn't see it on our 6.1.3.2 code so maybe a late 6.2.x.x but definitely in 6.3.0.0.

Re: PS3 dropping off the network

Is anyone else using 93H APs in the deployment?  Disabling the OTA updates did not work for me.

Re: PS3 dropping off the network

We are also using the 93H and have seen the same PS3 problems. I can also say that I have tried disabling OTA updates and it did NOT seem to fix the problem. I have been unable to get any students to troubleshoot further.

Re: PS3 dropping off the network

I called Sony to see if they were aware of the issue, and if they would be willing to support. You can guess with the PS4 out that this is not a priority.

Re: PS3 dropping off the network

We were having similar issues at Sacramento State with the ARM feature enabled on Aruba access points with PS3's 1st Generation.  Turning the Aruba ARM feature off resolves the issue where the wireless and wired network adapters completely drop connectivity/disable themselves.  Turning the ARM feature off might not be a longterm solution but this definitely verifies that this is an issue with the PS3 OS/hardware.  Does anyone know the PS3 OS version this started to become a problems in 4.5x?
