That may not isolate the NIC. 

I know on Gen 1 PS3s if the wireless NIC heard a packet it could not decode, 
both wireless & wired NICS were affected and inoperative, implying they used a 
common controller for both. Sony may still be doing the same thing with PS4.

Excellent advice! I like the idea of eliminating the console's wireless NIC 
while still using the wireless network.

If we were able to I'd also consider running a temporary cable across the hall 
to the eth1 port on the AP.

Which wireless vendor are you?

We had a lot of timeouts, lags and disconnects on Cisco gear (1810s)...   
-firmware was determined to be the cause and patches are ongoing  (it has been 
covered in length in posts)

Having said that, without a packetshaper like device/rate limiting  (we use 
Exinda's) the users are susceptible to bandwidth hogs and that could latency 
delays.  Remember, video download and audio are buffered and most web traffic 
can be rebuilt behind the scenes...  Gaming is one of the few things that 
requires immediate timely access (same with VOIP)

Has anyone received feedback from users about lags or drops while gaming on 
wireless?

We support gaming consoles on a "devices" SSID  (PSK with MAC auth). We're 
trying to resolve reports from a user with a new PS4 Pro who is experiencing 
issues while gaming. For perspective, it was reported that during a 3 hour 
gaming session the user experiences about 8 lags and 4-5 disconnects. Lags are 
described as freezes for a few seconds which auto-correct. Disconnects are 
described as the whole console losing connectivity and a "Retest Network 
Connection" is required to get it working again (though time might also be a 
factor in getting it back on).  Apparently most issues occur right after power 
up then smooth out (user turns on console just prior to gaming). Logs show the 
device jumps APs every now and then but we haven't been able to match this up 
to the user's experience yet.

Our eduroam and open (CP) SSID seem to working fine. Client density is not a 
factor and the user reports great speeds.

Are reports of gaming lag on enterprise wireless common or the exception? 
What's the first things to check to identify where lag comes from? Should 
device roaming introduce lag or can that occur lag free?  I realize we're 
talking UDP with gaming with no buffer so issues would present themselves more 
readily while gaming.. The PS4 is currently in user debug and we've asking the 
user to record timestamps to try to corroborate logged events. We have a TAC 
ticket open with the vendor.

Any shared gaming experiences or advice about how to make gaming consoles happy 
would be appreciated.
