Adapter works fine with firmware-5 (WLAN.TF.1.0-00002-QCATFSWPZ-5www)

But when both firmware-6 (WLAN.TF.2.1-00021-QCARMSWP-1) and firmware-5 are in the same directory it tries firmware-6 with the above results and no wifi.

So my temporary solution is to remove firmware-6 and notice txt file from directory but this isn't an optimal solution.
