we have many devices with RFID problems.

We have the WAP4 with LF RFID cap.

Our problem occurs repeatedly with several devices as follows:

It is no longer recognized by the reader to fix this error has so far only screwed, plug from motherboard pull, re-plug and screw proven.

Then it goes again for 3-4 months .... sometimes however only 3-4 weeks.

Each time the devices have to be sent by the customer which causes failure and dispatch costs.

Is there a way to fix this?

It never succeeded:

- hot-, cold-, cleanboot
- complete reinstallation

Also, it is strange that the LF drivers are still in the alpha stage (for over 2 years): Or are there already new?
