Link speed has nothing to do with wireless bandwidth; bandwidth is usually half as much. Working in several modes at once reduces the bandwidth, so I recommend setting the specific standard you need.
802.11b (2.4 GHz, up to 11 Mbps, legacy low speed protocol)
802.11a (5 GHz, up to 54 Mbps)
802.11g (2.4 GHz, up to 54 Mbps)
802.11n (2.4-2.5 GHz / 5 GHz, speed up to 600 Mbps)
802.11ac (5 GHz, speed of about 6 Gb/s when using multiple antennas)
802.11ax (1-7 GHz, speed up to 10 Gb/s)
Ethernet is the IEEE 802.3 group of standards
WiFi is the IEEE 802.11 Group Standards
WiMAx are IEEE 802.16 Group Standards
IEEE (Institute of Electrical and Electronics) is the Institute of Electrical and Electronics Engineers, a world leader in the development and implementation of new communication standards (both wired and wireless).
Signal levels can be as follows:
-90..-80 (bad)
-79..-70 (medium)
-69..-50 (good)
-49..-30 (very high, it is recommended to reduce to -50)
