Wireless Internet speed depends on two factors: 1. Wireless link speed; and 2. Ethernet speed of the AP.

1.

How to check the associated/link speed on a wireless client

You may check the wireless link speed of your client devices. For example if the link speed is around 80Mbps, then Internet speed could be around 40-50Mbps.

2.

EAP110-Outdoor Ethernet port is 100Mbps only, that means in theory, the maximum Internet speed of EAP110-Outdoor is just 100Mbps.

Thank you for this.

I checked with my iPhone SE 2020, which can get up to 140Mbps from my router over WIFI. When I'm standing next to the EAP-110 I get around 40Mbps.

And again the distance the EAP provided was also very disappointing.

Are there other WIFI settings I should set on the EAP? Really didn't change anything.

Or look to another EAP?

Thx

You can try to change the wireless channel of the SSID.

1,6 or 11 are recommended.

However there are so many limitations on 2.4Ghz.

I have EAP225-Outdoor and EAP245 both of them have better speed performance on 5Ghz.
