When I connect USB modem with Mikrotik, it works correctly.
I’m using PPP client to connect to USB. But after it authenticate , connect and take IP from ISP, It disconnect and then write “resetting link” at status PPP client interface and didn’t make anything else.
at logs it shows
1- The remote peer is not responding
2- disconnect
3- resetting link
how can I solve this problem ?
Thanks & Regards

You say it works correctly. Please clarify what works correctly.
Hello,
Thanks for your answer.
I mean with “works correctly” that when I connect USB modem to Mikrotik, the USB modem take IP from ISP and go through to Internet " for example I can ping google.com"
But after it authenticate , connect and take IP from ISP, the USB modem disconnect and then write “resetting link” at status PPP client interface and pending at this status.
at logs it shows
1- The remote peer is not responding
2- disconnect
3- resetting link
how can I solve this problem ?

What version Mikrotik?
What modem?
How long does it stay connected before it disconnects?
Thanks for your answer,
Mikrotik version is 5.7.
modem is HUAWEI Mobile Connect Model: E160G HSDPA USB Stick.
and I stay connected about 2 Minutes then the problem occurred.
Huawei modems are a problem with Mikrotik.
