Usage experience might be depending on your hardware-revision (see below).
I for myself have a rockstable wlan (since around 01/2018) without dropouts even for long filetransfers. But… there are two flaws atm
- big flaw: 160MHz is not running out of the box, even with other board-2.bin and firmware-5.bin files. But I won’t give up on that…
- small flaw: in hot surrounding (but maybe also or instead of that because of a hardware-flaw of the first TO-board-revision) the card might not come up on warm (re)boots. In that case discconect power plug, wait for some minutes, reconnect power plug.
In total I’m hoping for a hostapd supporting 160MHz and am apart from that quite happy
