LHG 5ax need help

I used to have 2 SXT AC units until they died from old age and a storm (the plastic disintegrates). Working Fine until die.

I bought two LHG 5ax and configured it as I had it. Basically, I created a bridge, assigned the interfaces, assigned the IP address to the bridge, and configured the network.

Both the access point and the station are connected (Recorded and stable without drops or interruptions) ,but I don't have internet or network access. Something is missing, and I don't know what it is. (things have changed a lot)

Post the configurations of both devices, instructions here:

Classic mistake. Use configuration.mode=station-bridge instead.

Doesn't the level 3 license now allow access point mode? Shouldn't one antenna be in bridge mode (the AP one) and the other in station bridge mode (the client one)?

To clarify:

Mode station

This is standard mode that does not support L2 bridging on station - attempts to put wireless interface in bridge will not produce expected results. On the other hand this mode can be considered the most efficient and therefore should be used if L2 bridging on station is not necessary - as in case of routed or MPLS switched network. This mode is supported for all wireless protocols.

Station has no L2 (please read as "bridge") connectivity.

The wrong words and concepts are being used,
The interfaces are managed by the "wifi" drivers and not the "wireless" ones.
They are not the same thing, and they are not configured in the same way (and not have the same features).

@verytired If you simply searched for "PtP with LHG" in the forum, you found this...

Well, I tried all the modes before posting (yes, including both as access points). This was a strange problem.

After a lot of testing, I did a test with my mobile phone (set to AC) and I had a connection but no internet access (interesting). I did a factory reset, deleting all configurations, and started from scratch. Then I had a connection and internet on my mobile phone.

I repeated the same process on the station (in bridge mode) and nothing, so I repeated the reset and it started working minimally (I had network access, I could access the router and files on my NAS, but no internet). Finally, I restarted everything: router, PCs, access point, and station. After 20 minutes of checking the internet, it started working. Now everything works without a problem. I've restarted it several times and made a backup just in case.

Post the two configurations you have now (working).
It should be possible to highlight the differences with the ones you posted earlier.
In any case a working configuration can be useful as an example for other people having hte same issues.

usin the export file=xxx get the same i posted before only chage date/time (Some changes to the Wi-Fi, now in AC mode, but for better speed and signal, which I changed recently, it doesn't affect anything.) .I got it working this morning in (modeAX) the same configuration only it was a little slower in speed tests (very simple, transferring a file).

I think there was some corruption or it was blocked not using the configuration I entered at all. the same configuration.

the same only change station to station bridge (But I tried them all, none of them worked) and the wifi after it started working
