Archer AX18 terminating PPP session every minute or so
Hi there,
We have two Archer AX18's (EU model with 1.2.1 Build 20250729 Rel. 73566(4555) firmware) in two separate locations, both having the same issue.
They are both dropping the PPP session very frequently, then immediately reconnecting. In both locations the fibre ONT stays connected, so it would appear to be a router issue.
I noticed there is a beta firmware for the AX12, which may be for the same issue? So wondered if there is a similar beta version for the AX18?
Any help would be appreciated.

Hi,
Since the files of regular firmware versions for the Archer AX12 and Archer AX18 are identical, beta versions should be too.

Thanks for the confirmation. I have successfully updated to the beta firmware, but unfortunately it hasn't resolved the issue.
I'll keep testing and report back with any more findings.
