Keep losing internet connection

[Heifer624]

Any help here guys please. WE826-T2 rooter with EP06A and Visible... Having to do the following commands to get internet back up every 6-8 hours.

Code: Select all

AT+QCFG="usbnet",2
AT+QMBNCFG="AutoSel",0
AT+QMBNCFG="Deactivate"
AT+CFUN=1,1

This probably won't be helpful to you but after 4 years of using a sim without any issues, in mid-late 2020 I started getting disconnects during peak hrs (on/off/on/off) all the time, what helped me (mostly) was grabbing another tower that was further away (the two close towers I think had congestion issues due to me being in a rural but dense area with poor internet availability). It still gets slower sometimes 5-9pm but stays connected (I'm trying to fix this with a network bridge/port balance of 2 connections/2 towers). Probably not the same issue you are having.

Is the usbnet reverting to something else?

[Heifer624]

Dude I'm a rookie. I have no idea if it was reverting to something else or how to even check.

Found my tower quit broadcasting band 4 for some reason and I had CA set for 4/13. So now I have reset to 2/13 instead. Will see what happens now.

No worries, we all are at one time. I still think I am.

You can query/check using the same commands you posted, with a slight change:

Code: Select all

AT+QCFG="usbnet"?
AT+QMBNCFG="AutoSel"?
AT+QMBNCFG="List"

At+Cfun=1,1 is a hard reset for the modem

At+qcfg="usbnet" is the modom to router communication protocol.
0= qmi mode
1 = ecm mode
2= mbim mode
3 = rndis mode, I think

The most common is 2 and 0
This is the one you may want to check is staying on 2, with the ? Command above.

At+qmbncfg="List" will show all of the dealios that command can set. The important thin is if the numerical listing (1 or 2 or 3 or.....) has ",1,1" after it or a "0,0" after. If they are activated there is a ",1,1" after the line number. Ie: 3,1,1 on line #3. The deactivated ones all have ",0,0" after its line #.
This is how you know if at+qmbncfg="Deactivate" worked or kept after a reset.
The only way it stays after a reset is if the command at+qmbncfg="AutoSel",0 worked. Putting a ? After "AutoSel" instead of the setting of ",0" (off) will return its setting.

If I wasnt on my phone right now, Id post pictures.

Thx Disney I'll give it a try when the wife finishes her teleworking today

Didney I think all these look ok ???

Box hasn't failed yet since reboot. I did change Bands to 2/5. Seems to be more reliable there.

Just a question, what kind of signal strength are you getting and what power supply are you using. Also, what tower ID do you have and did you verify it didn't change. The carriers are doing upgrades all the time now it seems, taking arrays down on one tower causing the router to register with another or reregister.

Your in MBIM mode. AutoSel is off. List proves none are active.

All look good to me.

I've noticed recently there are lots of tower/band changes going on due to all carriers upgrading their network to 5G. Therefore leaving the modem on auto-scan would probably work best at least for the time being. Once all the network changes are done, you could lock the bands again. You mileage my vary.

Code: Select all

AT+QCFG="nwscanmode",0,1  < Auto-scan bands
