I had an issue with Auto APN for KPN 4g provider. Sim card working in roaming. APN database contained KPN 4G and an initial connection was made, however router did not connect after a reboot and manual reconnection had to be made. It's all working when Auto APN is disabled and APN URL manually entered but in my case it is very important that AUTO feature works with this provider.
Separate question, does current stock of RUT240 comes with a new UI?
Thanks
