Re: User connects to VPN, but no network access

Yes, the modem for the internet connection may well be causing this.

Please capture pppd debug logs and share them.  These logs would show
the negotiated options at the start of the connection.  The negotiations
can be compared between working and failing client.

The negotiations can also be captured using wireshark or tcpdump.

Proving the modem at fault requires packet captures using wireshark and
tcpdump on both the client and the server side.

Since the ISP won't replace your modem for this, look for a firmware
upgrade for the modem, or a different ISP.
