Data type selection
An odd issue on this router over the past week. Not sure whether it is the router, the SIM card or the Network. 1. Always in the past the selected network type was 4G only. 2. A week ago this selection would not enable an internet connection. 2.Switched to 3G and the internet connection was established. 3. Tried a different SIM card from a different ISP and 4G only setting worked fine. 4. Replaced he original SIM card in the router and Selected 4G preferred setting and the internet connected to 4G+ but the 4G only setting still doesn't connect to the Internet.
The network is O2 UK.
Any insight gratefully received.
