Wireless Joint

Thanks, Yipzy. I tried issuing that AT command and got no response. When I SSH'd in I got this message:

root@ROOter:~# picocom -b 115200 /dev/ttyUSB2
picocom v1.7

port is : /dev/ttyUSB2
flowcontrol : none
baudrate is : 115200
parity is : none
databits are : 8
escape is : C-a
local echo is : no ...

I’ve changed the TTL and made sure time settings are synced. It still tells me Modem Present/Not Connected. AT commands don’t do anything. It just says “Waiting for a Response.” This happens either with or without a SIM card inserted. Even if the SIM is bad, the modem should still be able to respond ...

Without a sim card (or one that does not fit right) you are not going to show connected.


I have a SIM card installed now. It seemed to fit okay. I felt it click into place. It still shows "Modem Present/Not Connected."

Any suggestions? Here are how things look now:

Thanks for the suggestions about the power. It seems to recognize the modem better now...at least partially. This is what I get without a SIM card installed.

However, when I go to Miscellaneous Modem Features, I get this:

Very interesting. I would think the USB3 port on my router would supply enough, but maybe not. I’ll try out a secondary power supply as soon as I find a plug that fits it.

Thanks for the suggestions!

But, I cannot consistently get it to be recognized. Just a few minutes ago it was and then without touching any of the hardware, it says "No Modem Present," but still gives a Modem ID. Very weird.

I gave up with the ones that came with the USB3.0 To NGFF M.2 Key B Adapter Enclosure With SIM Card Slot on The Wireless Haven. It came with two MHF4 pigtails so I bought 2 more from NetSolution.Shop. Those clicked into place on nearly the first try. I ended up spending a little over 30 minutes ...

I have since got the two other MHF4 connectors hooked up and lo and behold, it recognizes the modem!

Here are the logs:

I finally got my Verizon SIM. I have the Quectel EM20-G modem mounted in a USB3.0 To NGFF M.2 Key B Adapter Enclosure With SIM Card Slot. I only have two of the MHF4 pigtails connected at the moment. I have it currently plugged into a Linksys WRT3200ACM running the latest (as of yesterday) Goldenorb ...

That’s a great option too! It will be fun to play around with it this weekend.

Thanks for the link on sending AT too.

Thanks, Viper67857,

As long as I can adjust APN stuff on the Asus, along with AT commands, I should be good. I’ll post an update once things are hooked up with speeds, etc. When you used your Asus router, do you remember if you just chose the 3G/4G option under USB Application settings? That’s how ...

Excited to have a Quectel EM20-G modem with the M.2 enclosure arriving this Friday. I didn’t go with a router from The Wireless Haven because I love my Asus AX-88U. I have the latest Merlin running on that and it has the hardware chip to make OpenVPN (connected to ExpressVPN in this case) really fly ...
