<div dir="ltr"><div><div><div>Thanks Aleksander, Bjorn, Markus ! The qmicli to change from raw-ip to 802-3 did work afterall - what I was missing yesterday is that I did not do an rmmod and modprobe of cdc_qdm and qmi_wwan. Today I reissued those commands and did rmmod and modprobe again and with that it worked.. Couple of qns below<br>
<br></div>1. I see that the qmi_wwan.c already has a "hack" in place to detect raw-ip Vs 802-3 and switch modes appropriately as explained here (<a href="http://www.mail-archive.com/linux-usb@vger.kernel.org/msg19918.html">http://www.mail-archive.com/linux-usb@vger.kernel.org/msg19918.html</a>) - so is that not sufficient to workaround this issue ? Why would we need this qmicli forced setting on top of it ? Just for my understanding ..<br>
<br></div>2. The qmicli force 802-3 at times takes multiple attempts (multiple times the cli has to be issued) before it finally reports that its operating in 802-3 mode. I am assuming its something related to how fast/slow the firmware processes these commands ? Any ideas ? <br>
<br></div><div>Once again, thanks a lot to all of your for helping with this .. I was calling up AT&T with this problem report and was not getting anywhere with that :)<br><br></div>Rgds,<br>Gopa.<br></div><div class="gmail_extra">

I can confirm that this made the new firmware work for me.<br>
<br>
Seems like the device ended up in raw-ip mode after upgrade.<br>
