Hi @pcho

Which firmware version are you using? If you are not in the latest firmware, please download the latest one and retry.

You can get the firmware here: Firmware

Continuing the discussion from GL7500 PPP Connection issue:

I am using
ATI9

GL7500.A.2.13.151600.201802201800.x7160_1

GL7500

GL7500.A.2.13

x7160

Is there any difference between HL7588 and HL7688 in
term of connectivity?

Hi pcho,

It is not the latest firmware version. Please download the latest one and retry.
You can get the firmware here: Firmware

No, there is not.

Please find the PPP configuration and log files for your reference. PPPD.zip (2.7 KB)

Hi Donald,

I am planning to abandon PPP and migrate to wwan interface.
I was able to connect using AT commands
Like belows:

AT+CGACT=1,1

AT+CGPADDR=1

AT+XDNS?

AT+XDATACHANNEL=1,1,"/USBCDC/0","/USBHS/NCM/0",2,1

AT+CGDATA=“M-RAW_IP”,1

Routing Table

Kernel IP routing table

Destination Gateway Genmask Flags Metric Ref Use Iface

default hitronhub.home 0.0.0.0 UG 0 0 0 wlan0

192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0

then I set my network (debian OS) as instructed on Sierra Wireless manual

sudo ifconfig wwan0 10.102.34.3 netmask 255.255.255.0 arp up

sudo route add default wwan0

Kernel IP routing table

Destination Gateway Genmask Flags Metric Ref Use Iface

default 0.0.0.0 0.0.0.0 U 0 0 0 wwan0

default 192.168.0.1 0.0.0.0 UG 0 0 0 wlan0

10.102.34.0 0.0.0.0 255.255.255.0 U 0 0 0 wwan0

192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0

Then I ping to 8.8.8.8 (ping -I wwan0 -c4 8.8.8.8)
I got an error not reachable
It seems like something is missing or I did something wrong.
Any help will be appreciated.

Regards,

Phillip
