@infiniteloop said in Creailty CR 10S PRO / Duet WiFi Signal strength concern:
Strictly spoken this is illegal in most countries, but it works very well
if you're refering to exceeding the EIRP then you probably need a highly directional antenna to break compliance, but its a good point - firmware option to reduce the tx power should be made avaiable when the product is available with external antenna connectors from the manufacturer.
