r720 - iOS performance horrible IF WPA2 / encryption enabled on FW 110

[stephen_hall_60]

This actually also applies to r710 only with FW 110 as well.   When using standalone FW  110.0.0.0.663 , if i enable WPA2 encryption, several test iOS devices will not see above 90mbit in either direction (speedflex or speedtest.net ). 

If i disable encryption, speeds go up to what they should be ( up to 550mbit real BW , depending on the iOS device's wireless capabilities).

This does NOT occur on FW 104.x (r710)  nor on 106.x (r720),  nor on unleashed 206.x ( r710/r720).   (its only w FW 110.x  and only on r710/r720,   ie issue is not occurring on a r600 we have w fw 110)

In my tests im only using/enabling the 5ghz radio.  (factory resets between FW changes / tests)

The issue also does not seem to affect other non iOS client devices (ie those are showing full speeds w ENC on).

(this is all in our office / lab,  not in the field as its our first test/experience w the r720)

I have reproduced the issue with both poe AT and when using the ruckus 60w 48v AC adapter (r720)  or 12v AC (r710).  So its not a power-mode issue (ie these two APs do have special POE power requirements).

My hunch is that something on the AP is keeping iOS STAs at 802.11 N or maybe only 1x1 chain of AC when WPA2 is enabled.

(im ofcourse testing with WPA2 , PSK, AES,  I have tested other ENC settings and the issue is the exact same, its only with ENC disabled do i see full, normal speeds on ios)

anyone have any ideas or suggestions?  These are on 2x new r720  (and r710 we already).

(i am aware of the other large thread w iOS issues and recent FW, but those are all lack of any connectivity on iOS,  the issue here is simply speed, not ever a lack of connectivity)

thanks

Hello all,  

I just loaded Unleashed firmware 200.8.10.3.243 on both my R710 and the new R750.  I have consistent 580 Mbps and 860 Mbps respectively prior to the firmware upgrades (1 Gig speed in from ISP; used Speedtest app on a MacBook Pro).  I get 1/3 of those speeds after the upgrade.  The speed reverts back to normal when the encryption method is set to "None".  I noticed that when I use WPA2, WPA3 or any of the additional settings, the speeds are only 1/3 of normal.

I understand from prior posts that this was an issue a few firmware versions ago.  For me this appears to be still an issue.  I am entirely open to any suggestions.  

Best regards

Hi All,

I fixed the issue on the R710 by reverting to an earlier Unleashed Firmware version (200.6...).  The R750 is at full speed since making it "Master". 

Best regards, Tim

This problem was resolved in Unleashed versions 200.8.10.3.278 and 200.7.10.202.118, as reported in thread Slow Download Speeds R710 Unleashed.
