The wireless is Wifi standard 802.11a/b/g/n/ac 2×2 867Mbps, the line transmission is 1000BASE-T Ethernet 1Gbit/s. It sends in 2.4GHz band.
1Gbps (125MBps) is the fastest ethernet transfer speed. Although I've had someone report 600-700 mbps, and that cheaper motherboards may be around 100-200mbps.
If you're not getting good speeds on data transfer via ethernet cord with Leo then reconfigure the network adapter (and use a cat6, or cat7, or cat8 cable):
1) Connect the scanner to your laptop/desktop directly with an Ethernet cable.
2) Enable a DHCP server on the scanner itself (Settings - Network - Connect to Leo - Wired (DHCP server).
3) Make sure the connection is established.
4) Go to the Ethernet settings on your laptop/desktop (Start - type Ethernet settings in the search field).
5) Check the properties of the network connection. Make sure the maximum available speed is 1000 mbps.
6) If not, go to the Network Connections settings, click on Change adapter settings, right click on the network, Properties, then Configure, Advanced, Speed and Duplex. Check the value to the right of the list.
7) If there is no 1 gbps option, change it to Auto Negotiation, apply, reconnect to the DHCP server and check the speed in the network properties one more time.
