R500 not compatible with ac-7260

Just installed zd1100 and r500s, worked ok when eventually got hold of relevant firmware. (new customer) Having problems connecting tosh with intel ac7260. Seems problem is to do with channelfly and .h messages. Works if select one channel as this disable channelfly. (tried on standalone unit). Been asked to manually set channel in ZD as test but need to check interference. Other option to set run stop time. Running build 101 and have downloaded build 108 but not sure if it includes any fix. First ruckus install so not overly happy.

Hello Trevor,

Which version are you talking about?

Could you please elaborate a little bit more your tests and your results?

Initial 9.8.0 GA release for R500/R700 had issue ZF-7357: Not using 2-stream rate with Intel 7260 2x2 11ac NICs.

Firmware builds 9.8.1.0.101+ have the fix to improve performance for these clients.

Next 9.8 MR2 release is expected in Nov14. Not sure if 5G background scanning
will be enabled or disabled by default. If not enabled, running ChannelFly for a
period of time will allow your APs to decide on other than channel 149. Stopping
it after a period of running, was recommended to prevent problems in .106/.108
interim builds.

Just disable channel fly and only use background scanning. Or just let channelfly run during the night when there are no clients (for about 6 hours) make sure to reboot all access point before you leave, you can configure this under radio group options and services. Also what version are u using? Is the client firmware supporting 202.11h channel change announcements.

Newbie to Ruckus I believe disable command is via the command line
but I do not know the syntax, can you help.
ZD is 9.8.1.101.
Intel say they support 802.11h
running latest intel s/w.

Hi Trevor,

The ZD WebUI is meant to be more user friendly than command line. From the
Configure tab, Services on the left, the boxes to configure 2.4/5G channel selection
(self healing) are found. We suggest to check the 5G box to enable Automatic
adjustment, and pick ChannelFly from the dropdown (rather than Bkgd Scanning).

Apply this change and let your APs use the algorithm which entails an off-channel
scan an building of an internal database with interference seen. After at least two
hours, the AP ought to have selected a better-than-default channel. You can then
change the ZD Configure/Services, and uncheck the 5G Automatically adjust box.

This only applies to 5G band when you have our newest 11ac AP models in use.
You can use background scanning or channelfly algorithm on your 2.4G channels,
and leave it running. I hope this is helpful.

Thank you for this helpful suggestion! So just to clarify, I should check the automatically adjust power box for 5GHz on AC AP's? Does it do harm on a heterogeneous deployment of 7982's and R700's? Just trying to reconcile this with the General advice that ruckus recommends allowing Beamflex to do its thing instead of allowing the AP's to decrease their power levels.

Never mind - looking at the ZD pane, it makes more sense. There's 3 settings that start with "Automatically Adjust", and you weren't implying to turn on the power reducing option.

We are having major issues with our R710 deployment.  Looks like the Lenovo Chromebook N21s are using the same Intel 7260 card.  Anyone having issues with these?

I have had nothing but problems with the 7260 and my R710's.  Impossible to recreate the issues for support, so we are left with a less functional wireless network.

Yes, we have an open case currently.  00344561.  We just keep chasing our tails trying to figure out a solution.  If you have any progress, please let me know.  We are having major roaming issues and traffic delay issues.  If we hardwire the connection we are good, or most other devices work pretty good.

Likewise, I would love to hear if you've made any progress. Someone has to have solution, as this chip is over a year old at this point

I too have the r710's installed along side Lenovo N21s. We had lots if issues with dropped packets and disconnections. I turned channelization from AUTO to 80 and that stopped the dropped packets. Still working with Ruckus though to resolve low throughput to my N21's. I talked to Lenovo about the bad cards. They told me to not expect anything from them.

Does Ruckus think this has something to do with the AC7260 nic? The Chromebook? Something with their firmware? How you have things configured?

With most client adapters, using the latest drivers often provide latest fixes, both public and internal.
I've seen a couple posts in Intel/Microsoft forums that also provide client side settings that greatly improved performance (ie from 54mb to 866mbps)

I don't have a PC/Apple/Chromebook with this Intel adapter, only that this info/advice can be found on the web:

Driver version 17.0.3.2+

https://downloadcenter.intel.com/search?keyword=Intel%c2%ae+Dual+Band+Wireless-AC+7260 


802.11n Channel Width for 2.4 GHz : Auto
802.11n Channel Width for 5.2 GHz : Auto
Ad Hoc Channel 802.11b/g : 1
Ad Hoc QoS Mode : WMM Disabled
ARP offload for WoWLAN : Enabled
Bluetooth(R) AMP : Enabled
Fat Channel Intolerant : Disabled
GTK rekeying for WoWLAN : Enabled
HT Mode : VHT Mode
Mixed Mode Protection : CTS-to-self Enabled
NS offload for WoWLAN : Enabled
Preferred Band : 1. No Preference
Roaming Aggressiveness : 5. Highest
Sleep on WoWLAN Disconnect : Disabled
Transmit Power : 5. Highest
U-APSD support : Disabled
Wake on Magic Packet : Enabled
Wake on Pattern Match : Enabled
Wireless Mode : 6. 802.11a/b/g


PS.  The 54mb CU had TKIP on his WLAN, use WPA2/AES on PSK WLANs.

Unfortunately we cannot download drivers from Intel's site since they are Chromebooks.  :(

I'm sure both of the two companies who make your PC/radio card are trying to solve this too,

but browsing the Internet, I have found a suggested Chromebook fix:



I created a config.properties file in my
site folder and added the following line:



config.uapsd_enabled=false



and Provisioned the UAP

Can you link the site?  I am not exactly sure where this is supposed to be entered.  On the google management/Zone Director/Chromebook.  Thank you for your quick response.

I think I found it..  We had these APs and just removed them for this reason..  interesting.

I'm not admin-wise in the world of Chromebooks, so hope others on that platform can be of assistance.

Yours is the link where I found the advice.

Ok, yes, this fix is only for the Unfi wireless controller for Ubiquiti access points only.  I made this exact change on our UBNT server and it helped.  Unfortunately this is only a fix for Ubnt equipment only (Which is super cheap and we removed all the UAP-ACs about 1 month ago.). It is not for the very costly and well known wireless company Ruckus.  :(

Reported problems with R500s about a year ago updated everything I could but still had problems with tosh laptops connecting. Problem still with us. If laptop does't connect then pupil walks down the corridor to another ap which connects and then returns to the classroom and all is well. On Friday I will check 7260 chip driver version and the d1100 and r500 versions. They don't have Chromebooks, all other devices connect ok.

Hi Trevor,

   It sounds like you might have an AP in a "stuck" state, perhaps due to interference, if clients are

unable to connect, but connect ok when roaming a short distance.  Can you also upgrade your ZD

to the latest 9.10.1.0.59 for ZD1100s, which will have our latest bug fixes and performance

enhancements too.  Then if on Intel 17.0.3.2+ too, should be smoother sailing.

We have the same issue where the AP first connects with the chromebooks and then when they go to sleep or drop for whatever reason, this same AP will not pick them back up again.  We have taken the AP off-line countless times and I am wits-end.  I will attempt to upgrade the firmware to the latest version and see what happens.  I am suspecting possible AP interference in the hallway where it is.

QUESTION:  Does the alignment of the AP make a difference?.... meaning mounted horizontally versus vertically?

Again I admit up front I have not used Chromebook personally, but previous advice about ac-7260 included disabling U-APSD/sleep mode.

Internet sources offer some user configuration, and mentions a "Keep Awake" extension from the Chrome Web Store for this purpose:
https://greenido.wordpress.com/2012/12/30/how-to-prevent-your-chromebook-from-going-to-sleep/
http://www.omgchrome.com/extension-to-stop-chromebook-sleeping/

Ruckus indoor model APs (including R700, R300, R500, R600, R710) provide the best coverage in a Horizontal (flat) position.
Ceiling mount is good for floors above/below, but even sitting on top of a shelf or bookcase is ok.

Chromebook OS updates can help too! 

Ruckus Tech Support reports that Google OS 47, or current latest, also includes driver updates that significantly improved Chromebook wireless performance. 

How to check for and install OS updates:
https://support.google.com/chromebook/answer/177889?hl=en

Can anyone in the group update their Chromebook and let us know 1) what version it is, and 2) if it helped your wireless experience?  Neal?

Our Chromebooks only update to 46 as the latest os available unless I go to the beta.  After changing to beta, nothing changed in reliability unfortunately.

I'm not certain what to do here. Are Chromebook users with 7260's out of luck? Surely, this isn't the first Ruckus has heard of this issue, is it?

Our chromebooks are already at version 47.x.x.
Is there something special I need to do in order to upgrade our ZD1112 to the latest version of firmware?  I have downloaded version 9.10.1.0.59.  Is it as simple as pointing the ZD to the file on my PC?

Prior to any upgrade, save a backup of your current configuration (Administer/Backup), and add your current version digits to the filename to remind you what version it came from.
ie.  GWehe-ZD1112_db_983014_111715_16_10.bak  (if you were on 9.8.3.0.14)

Second, read the Release Notes for the ZD 9.10.1 version you intend to upgrade to, and make sure all your AP models are supported.
Some Legacy APs like 2942/7942 are EoS.
https://support.ruckuswireless.com/documents/830-zoneflex-9-10-1-mr-release-notes

Then, from Administer/Upgrade, you click the Browse button and load the image you have downloaded to your PC,
and when prompted to save a backup, you can skip, and click Upgrade to continue.

The ZD will upgrade and reboot.  Your APs will reconnect and each get upgraded to the new ZD firmware version.
Watch from Monitor/Access Points page, as they go from upgrading firmware, disconnected, provisioning, to Connected.

A typical ZD1100 upgrade shouldn't take more than 15-20 minutes.

Are there any updates to the current 9.12.1.0 build 148 on the ZD3000?  Thnx

Just to echo this question, should we be using the 9.10 firmware recommended in this thread?  What if we are using 9.12? Should we expect the same results?

Just tried BETA 47.x.xxx. on one chromebook.  No change on my end.
