Archer C60 V2 WiFi issues

I am using snapshot about a month old and I am finding reliability issues with the WiFi.
The issue is not specific to 5Ghz either.
Anyone faced this?
Is it worth trying latest snapshot, if some fix have gone in?

Same problems here with Archer C60 V2.

I'm using OpenWrt 18.06.2 with MWAN3.

2.4G works fine in most cases, however the 5G almost does not work, always turning off.

Tried to config , Legacy, N, AC, 20MHz, 40MHz and 80MHz, but make no difference.

What a bummer.
If not for this wifi issue, it could have been a good dual-band replacement of the old TL-WR-841n.
It has decent specs too with flash/RAM as 16M/32M.

  1. 16/32 are not decent (32MB RAM is too little)
  2. C60 v2 has 8/64MB

Sorry, I was speaking from (bad) memory.
My point still remains valid.
Anything above 8MB is enough right now, will fit most of the popular apps for such home use router.
64MB RAM and CPU is at par with older "high-end" 1043ND and definitely much better than openwrt starter router 841N.
But for some reason wifi wouldn't work on this.
I guess only next reliable device is Archer C7 at 3x cost. If anyone knows better please update.

This statement isn't quite true, considering that samba4 -a popular dæmon often requested for OpenWrt- just barely fits into routers with 'just' 16 MB flash. Yes, we can certainly discuss if a cifsd has any business of running on a router, but that's a different topic.

What users expect from their devices within the expected useful lifespan of their devices differs, very personally I'd put my limit at 32/256 devices, with multi-core and preferably ARMv7 or ARMv8. But my focus is always on retaining my options over the long span, avoiding to get limited by hardware specifications even in their second- or third use. Especially if you're buying in a quantity of 1-3 devices, a reasonable markup for better hardware specifications is often worth it.

And surprisingly both have very similar chips.
C60: WLAN HW: Qualcomm Atheros QCA9561, Qualcomm Atheros QCA9882
C7: WLAN HW: Qualcomm Atheros QCA9563, Qualcomm Atheros QCA9880
Didn't face any issue on C7, whereas on more than 1 sample of C60 I have faced issues.
The issue was very elusive and failing in weird ways; would work on one wifi client and not other etc. For 100Mbps ISP C60 is otherwise a good option and C7 is overkill.
