Cannot login to LHG LTE18 via win box or webfig

Hi. This is a really odd one.

I have connected to the LHG via Winbox (MAC), changed admin password and configured the LHG for my APN etc and all seems fine. No other changes. Still using 188 ip etc. Serving DCHP and internet to LAN OK. Can surf internet all well.

Try and log back in to admin via Winbox (still MAC) and it will not connect - gives error “Cannot connect will try again in 5s”. It will not login again ever.

Only way to fix it is to reset to factory defaults.

Tried again using Webfig interface - works great first time, forces to change password. Configure APN etc and all working. Close browser etc. still working on DHCP and web surfing all OK. Try to login to admin page again and errors about interrupted connection and I cannot access the page.

Only way to fix it is to reset to factory defaults. Then it works fine again but only once.

On one occasion I upgraded the firmware on the modem etc as recommended and that was fine (until I logged out as part of the reboot) and then I couldn’t login again.

I have consistently repeated this 5 times only changing the absolute minimum (APN settings and admin password). It’s fully repeatable.

Any ideas? Otherwise this is going back as faulty because this is unworkable - but it doesn’t feel like a fault since it works to serve internet to the LAN. I just cannot make any changes- it’s one shot each time which is wrong.

Are you setting the APN via QuickSet? As that might be changing your config beyond just the APN, and leaving it messed up state.

Perhaps after reset-configure, and use Interface>LTE>“LTE APNs” and then set your carrier’s APN in the default APN profile, and uncheck the “Use Network APN”.

Also add your own account under System>Users and assign it to “full”, instead of using “admin”. Then try your new account after the 1st reboot.

Thanks. Will try your suggestion.

I’m not setting APN in Quickset as I have to set authentication. I will try unsetting the carrier APN tickbox.

Will update.

The “use-network-apn=yes” override at least the APN, so if set… your APN name is not used. And use-network-apn=yes is the default.

I don’t know how this works internally but suspect the “Network APN” is checked at startup. But if you update the APN profile… your new values are used, until reboot when it re-learns a the “Network APN” (e.g. from carrier via SIM/MBIM)…

Sometimes when you try to login using MAC on WinBox, virtual interfaces causes problems (like VPN’s, Hypervisors, etc). Try to disable all on your computer except your physical Ethernet connection.
