Hi wwadepohl,
You can follow these steps to check:

  1. Check different WIFI and LTE channels.
  2. Check whether filter or switch is used on WIFI and LTE RF trace, and bypass them if used.
  3. Change the WIFI antenna and LTE antenna and retest again.
  4. Whether to add a shield cover to the WIFI area, and whether the WIFI antenna and LTE antenna are too close.
  5. Try to reduce WIFI and LTE TX power.

Thanks !
