3G Modem configuration stop working after years ok!

Lork · September 8, 2024, 4:54pm

Hello all,

I'm getting stuck on a (maybe simple) problem.
I configured in 2017 a TP-LINK MR3220 with USB modem for WAN internet connection.
SW: OpenWrt Chaos Calmer 15.05.1

All worked fine until this June and since it I cannot get connection.
I've tried various configurations edit but none of them is risolutive.
This is my configuration:

And This is the logread (all day in the same loop).

Anyone know why "modem hangup" ?
I'm not so expert to analyse the chat and understand what is missing.

For me the realistic reasons are two: 1) modem hardware is broken due to its age. 2) my internet provider has changed something since june (anyway APN is correct).

Currently this is the lone 3G dongle to test. I've teste the SIM card on a phone and internet connection is OK. I cannot test the USB modem on PC because its windows SW dosen't support this provider (I cannot change the manually the APN).

Thanks to all.

Are you sure your carrier haven't killed 3G in their network ?

Interesting question...and....you are right
Sorry for the italian language link but, it is true....

Now I need to replace the USB modem with a 4G/LTE usb modem. It's correct? Do you know somethig economic on amazon and compatible with OpenWRT? Thankyou

P.S. Where did you read something in the logread that seems to be related to the 3G no supported by the ISP? Tankyou!

Grab a MF286D off eBay, they're 60€, which is pretty steep, considering they were 30€ a year ago, or two.

I didn't, but similar questions have been popping up lately, I only guessed.

Thanks a lot for your help!
