Issues connecting Android 10 to Cisco ME

dovla091

Hi, I had one problem which I found bypass solution, but I would like to share with someone, as I don't want that someone is wasting time as I did troubleshooting the issue.

My case was that I have 15 APs AP1832i set to Cisco ME, so 1 acts as a call it a  "controller", while others are getting the instruction. I have set latest version of firmware for APs - 8.10.105.0

Now I have Nokia 7.1 running Android 10 December 2019 patch, and what I found out that after upgrading Android to version 10 and patching Cisco AP1832i from 8.5 to 8.10, android phone cannot connect anymore.

After 1 hour of troubleshooting I found a bypass. By enabling WPA3 (along with WPA2), android 10 started to connect again.

My guess is either Google completely ditched support for WPA2 (for some reason), in favor for WPA3 or there is some mismatch between Cisco 8.10.105.0 for ME and Google Android 10. By enabling WPA3, phone can successfully connect to our network.

 

I hope I helped someone, and saved him/her some time in dealing with tedious troubleshooting

 

Best regards

these are good news for this community thread about some Android 10 devices from vendors Nokia, Sony and Xiaomi not able to connect to Cisco APs.

With the release of the new 17.3.1.9 code last Monday the problems have been fixed using different L2 security features (maybe working similar in recently released 16.2.4a last Friday). The only caveat there is when using 802.11r FT Adaptive (w or w/o over DS) and SHA1 or SHA1+SHA256 with COS-APs.

Config of the SSID must follow Cisco's workaround to disable FT Adaptive and Device Analytics.

This is the matrix for the tests:

Cisco IOS-XE code 17.3.1.9 final test.png

 

I've also tested Cisco AireOS 8.10.130 on ME and this is also working fine for Xiaomi devices disabling FT or enabling it, but not configuring adaptive which is expected behaviour.

 

NOTE: I've noticed some issues when trying to upgrade to ME 8.10.130 with errors aboout partitions. Finally I 've managed to solve it downgrading to 8.5.161 before, and then upgrading to 8.10.130.

 

Alternatively downgrade to latest 8.8 release or apply for the TAC supported beta 8.10 release.
Is all goes to plan, it should be released in the next 4 weeks.
Please note that I have another bug in that beta release, which makes it impossible for me to deploy it broadly.
So I suggest, if possible, to downgrade to 8.8.

Make sure to either upgrade to 8.10.130.0 or downgrade to 8.8.130.0. Both versions should work correct with WPA2 and PSK. Make sure PMF is Optional or Disabled. Don't enable WPA3!

i have also facing same problem in cisco ME upgrade os with nokia phone

Make sure to run up to date software, like 8.10.130.0 or even 8.10.142.0.


Hi patoberli,

i made this changes, but still no success. Pls checn the output

 

WLAN ID WLAN Name Status Protection
------- ------------------------- --------- ----------
1 Admin LAN Enabled Optional
2 Local LAN Enabled Disabled - still cant connect with my Xiaomi mi 10t - Android 10
3 Guest WLAN Enabled Optional

 

i am using 8.10.142 latest release

 

Any sugestions?

Just Degrade the firmware on Software Version 8.5.151.0
so Now onwards everything will working fine and not getting any problem from the client end.

just try this and relief yourself to that problem.

 

Hi Yogendra

This is weird, it should be working with 8.10.142.0. 

Can you share the full SSID configuration of the WLAN ID 2?

Can you try the following changes:

Disable AironetIE (advanced SSID settings)

Disable FT Support

Disable Load Balancing (and Band Select probably too)

 

You can test by disabling one setting and a time and then check again for stability. 

Hi Patoberli

 

Success! Thank you very much. i made this steps:

 

1. config wlan ccx aironetIeSupport disable 2

- No success
2. config wlan security ft disable 2

-Connected with Wlan

3. Disable Load Balancing (and Band Select probably too)

- didnt try

For greater stability, I would also disable load balancing. That actually kicks the clients out of the network if they don't roam when the WLC thinks they should roam. It has its positives and negatives sides, I generally leave it disabled in a mixed environment with many clients that I don't manage.
