Dear All

 

Good morning. We received many complains about the disconnection of Android 4 (or later) devices. The clients report that the connection continues for 5 to 10 minutes, then they could not connect to the wireless network anymore, and they have to reboot the device to get a new connection. I searched the internet, and found Android 4 has problem with PEAP mschapv2: “the mschapv2 setting is not saved and it always reverts to none”. (http://code.google.com/p/android/issues/detail?id=1386)

 

Do you have the similar issue, and how do you solve it.

 

Thank you, and have a nice day.

 

Yours,

Comments

That link is from late 2008 and early 2009, not Android 4.

 

The later postings mention certificate trust issues and Android 4.0.3  That is a client configuration issue. I notice that comment 361 refers to using Cloudpath XpressConnect to configure the client as a solution. All XpressConnect does is properly configure the 802.1X client. If XpressConnect can configure the client properly, there may be a UI bug, but the client can be properly setup to function. Since vendors modify the UI so extensively, a UI bug would not be surprising.

 

BTW, Cloudpath XpressConnect is a great product for getting a wide variety of unmanaged clients set up for your 802.1X network.

 

We use XpressConnect and I am not aware of any issues with Android 4.

Just to expand on Bruce's comment.

That posting references Android Cupcake, version 1.5, with a note that it was fixed in Android Donut, version 1.6

Android has been extremely stable on WPA2-Enterprise since 2.3 (and later versions of 2.2).

What's your Wireless infrastructure, and how do you have your SSID configured.  It might be a configuration issue.

I regularly have issues on both of my Android devices (Droid 4 running Android v2.3.6, SGT 10.1 running Android v4.0.4) where I have to manually disconnect/reconnect very often. We are using Juniper/Trapeze access points and controllers with EAP-TLS (certificates only, no user/pass auth) authentication.

Thank you, all I asked the Android 4.0.3 client to download the XpressConnect app, and his device connected to the network right away after running the app. Mike, what configuration issue do you think on the network side? We are using Cisco WiSM1, WPA2-Enterprise with PEAP-MSCHAPv2 authentication. Thank you.
