wifi disconnects after some time in the latest ubuntu BBB release

After I installed latest BBB ubuntu release https://rcn-ee.net/deb/rootfs/raring/ubuntu-13.04-console-armhf-2013-09-26.tar.xz wifi disconnects for some time n reconnects and disconnects, weird! I tried with another wifi modem n reproduced same behavior. wifi worked good with previous release, I hope so, as I never faced this problem.

Did you look here?

Okay, well if you are not using any "CAPES" there is one more thing
you can try..

wget http://rcn-ee.net/deb/raring-armhf/v3.12.0-rc5-bone6/install-me.sh

sudo /bin/bash install-me.sh

Is it the latest kernel? when does this kernel dates back to? I will post back after the installation.

Ur kernel fixed the wifi issue but it fails to symlink my cdma mode.
Below udev rule stopped working after running install-me.sh
SUBSYSTEMS==“usb”, ACTION==“add”, DRIVERS==“option”, ATTRS{bNumEndpoints}==“03”, SYMLINK+=“CDMAModem”

I want the previous kernel; for me functioning of CDMA modem is more important than wifi, what should I do now?

Fix the rule? You have the hardware..

Well, you could delete the install-me.sh and download/run the one for
the version that worked..

Installed ubuntu-13.04-console-armhf-2013-08-24, its working good.

are u asking me to rewrite the rule for the hardware? I didnt change the hardware! The rule worked with previous kernel.

In the new kernel the driver name given by udevinfo for my CDMA modem is something like “hce” where as in old kernel the driver name is “option”. the driver name in the old kernel is “option” is funny and the driver name in new kernel, “hce”, is uncomprehending!
