I feel like antenna not working at all because 2.4ghz internet is also slow. is it possible that at the time of soldering work, flux could be speard over UFL connector and thin layer remain over it?
No. I found without antenna attached, wifi is not connecting at all. so 2.4ghz is only working with antenna.
I have two axon. one is connecting both band. but new one is not
Are you seeing spread of flux on the UFL connectors?
