My PC Engines APU & APU2 were both unstable running 5.7 & 5.8. Specific to you question the mPCIe was equipped with an Atheros AR9281 WLAN Card. In addition my current move to a distinct/discrete access point was hastened by a buggy Zyxel USG20w that implemented Dynamic Frequency Selection (DFS) Please note the Zyzel & PC Engines both intermittently caused subnet “collisions” that necessitated power cycle of numerous networks hosts. After several months of stability with the USG a patch to remediate KRACK caused DFS to to run idle and disconnect during channel scan. In effort to remediate I configured a Hawking HW7ACB and found (subnet collisions) no longer an issue however occasional wireless disconnects occurred. After installing WiFi Explorer I determined that all channels (1 - 161) were noisy and contained overlap in my urban apartment complex. In effort to remediate I’ve configured a Hawking HW7ACB with channel number 165. At this point my network stability is considered good.
