which 4G/LTE-Chip is used? i found no information about this…

QCA9531 is a highly integrated and feature-rich IEEE 802.11n 2x2 2.4 GHz System-on-a-Chip

QCA4531 is a two stream (2x2) 802.11b/g/n single-band programmable Wi-Fi System-on-Chip

so both are SOCs for WiFi on 2.4GHz, no 5G or LTE

why lan-ports don’t support 1GBit/s?

i’m searching for a backup-way if my internet-connection (FTTH) is broken and i want to access my main-router over this way (LTE).

we use qca9531+mdm9X07

if you need 1000M RJ45 and Dual-band wifi , maybe design as below :slight_smile:




For my case (backup internet) i only need the MDM9X07+soc (mt762x) and 1 100mbit rj45 is enough…i need no additional wifi in this box. But if using as complete router device with multiple lan (switch),gbe on lan should be the default in my eyes
