Please share your usbconfig information for the device. I would like to see what the modem shows up as.

Whats your best speeds look like?

How do you configure by local address? Web landing page?
 
I want to get this off my chest.

Having a Snapdragon processor, used for the modem, on your regular computer could be considered a security threat. Who knows what OS that processor runs.

Here you have this 'blackbox' that could be communicating anything from your computer without you knowing. These are not simple modems but complex devices.

Scary but convient.

i connect to a web address of 192.168.100.1. I will then log in and configure my modem through it.

ugen0.4: <Android Android> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)

bLength = 0x0012
bDescriptorType = 0x0001
bcdUSB = 0x0200
bDeviceClass = 0x0000 <Probed by interface class>
bDeviceSubClass = 0x0000
bDeviceProtocol = 0x0000
bMaxPacketSize0 = 0x0040
idVendor = 0x05c6
idProduct = 0x9024
bcdDevice = 0xffff
iManufacturer = 0x0001 <Android>
iProduct = 0x0002 <Android>
iSerialNumber = 0x0003 <66bac037>
bNumConfigurations = 0x0001

another thing i realised is, when i m connected to the web withe the modem, i m unable to connect to the wifi or wifibox. only when i unplugged the modem, will i then able to connect to wifi or wifibox. is That normal.

i live in an area where i m unable to get broadband services. my only means is lte modem from mobile data. previously it was hotspot from my smart phone.

i did mention not able to connect to wifi or wifibox, whilst connected by the modem. out of curiosity, i connected my phone as usb thethering. surprisingly, i am able to connect to both ue0 n wifibox0
i opened up 2 iftop on terminal, n noticed only on ue0, is traffic. on wifibox, there is no traffic.

and speed on my ue0 is much faster

As far as I know there are no exploits for cellular modems.
Some of mine have a firmware over 10 years old.
This on a Snapdragon processor embedded in the modem.

I just feel its worth remembering you have a blackbox on the modem. It can monitor your computer without you knowing.
That yours is unbranded is interesting. I would expect Sierra modem to be NSA broken just like Huawei to be nation state actor compromised.
I can't believe they make an unbranded modem. It would be neat to track the IMEI, The first for digits are the manufacturer.
 
I hv stopped using it. I tested multiple times for speed n the best i could get was under 30Mbps. i suspected it is a hsdspa+ modem, instead of LTE, as the speed do not justify LTE speed. furthermore, what irks me most is, i m unable to connect to any wifi, whence using it as a modem. i find it so strange. back to search for a reliable LTE usb dongle
 
I have no idea why wireless would cut out. I made a MIMO device for portable Hotspot with a modem and Atheros in HostAP. Ran it off PicoUPS in my vehicle.
So I can say for sure wifi and cellular with work at the same time.

Sierra on USB Adapter with SIM. Huawei depending on preference. Some Telit works too.

This is the deluxe version. There are cheaper ones without antennas.
 
I also don't think that 30Mb/sec is that bad for cellular. Single Antenna inside?

I went all out with dual antenna in a praying palms setup. Sourced mostly from ebay. Pointed right at the tower.

This one looks cool. The price is quite reasonable. Thank you very much
