Issues with Netgear 340U latest firmware

[Gopakumar Choorakkot Edakkunni]

Hi Aleksander,

Thanks a lot for the suggestions. I tried them out, but that did not solve
the problem. I upgraded to libqmi 1.10.2 to get the latest clis .. I cross
checked with a couple of other people with Sierra/Netgear 340U modems
running linux and they are facing the same issue too. The  firmware version
just before this latest one was all hunky dory and great, unfortunately the
upgrade to the latest has caused this issue.

Before issuing the command you suggested:

wwan0     Link encap:Ethernet  HWaddr C2:4A:EB:3B:51:7C
          inet6 addr: fe80::c04a:ebff:fe3b:517c/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:139 errors:0 dropped:0 overruns:0
carrier:0                         <<<<========== These are DHCP packets
going out
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:48174 (47.0
KiB)                                       <<<<========== No response


Now I issue the command:

root:~# qmicli -d /dev/cdc-wdm0
--wda-set-data-format="802-3"
[/dev/cdc-wdm0] Successfully set data format
                        QoS flow header: no
                    Link layer protocol: '802-3'
       Uplink data aggregation protocol: 'disabled'
     Downlink data aggregation protocol: 'disabled'
                          NDP signature: '0'
Downlink data aggregation max datagrams: '0'
     Downlink data aggregation max size: '0'

As seen in ifconfig below, it has no change (DHCP requests have been going
on continuosly in the meantime via udhcpc) :

root:~# ifconfig wwan0
wwan0     Link encap:Ethernet  HWaddr C2:4A:EB:3B:51:7C
          inet6 addr: fe80::c04a:ebff:fe3b:517c/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:306 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:115308 (112.6
KiB)                               <<<<<=========== Still no response

Rgds,
Gopa.
