That was the first thing I noticed.
The signal strength was minimal to my home WIFI router.
After opening the module I realized that the module has neither an internal nor an external antenna!!
Look at the pictures.
So I added another Access Point to my garage. AP in the garage is connected via ethernet cable to my router.
Access Point is now 30 cm away from the WIFI module! And the module now has a maximum signal.
At my Access Point in the garage, I see there is network traffic between the WIFI module and garage AP.
So the signal is not the problem here.
BTW my board is revision 3.0.0 ?? And still has that issues ??
Maybe revision 10 will work properly...
and maybe they add antenna ?
And software version 10...
