The hAP ac² (RBD52G-5HacD2HnD-TC) is not suitable for AirLink with Oculus Quest2, and it's a software problem.

Hi friends.
I have an hAP ac² router and I was completely happy about it, until I bought an Oculus Quest 2.

The AirLink is almost unusable, because of lags. The picture streams from PC, so any freezes are very noticable. It happens every few seconds.
At 5 GHz, it’s a nightmare, at 2.4 GHz the situation is a lot better, but there are still noticeable lags.
I tried to play with various settings, from the similar topics on this forum - nothing helped.
(There are not much interfering channels, changing the frequency/distance/channel width doesn’t help, enable or disable WMM doesn’t help too)

So, I tried to run OpenWrt on it (there is a way to run it in memory without changing the original firmware of the router) and…
And it magically solve the problem! The lags are fully gone, the AirLink stream is continuous now.

I think this is the best proof that the problem is not in the hardware, but is in the software part.
I hope the developers of RouterOS would find and fix this bug… Because I’m not the only one with this problem. Oculus Quest is very popular - the further, the more people will complain about it…


There is no need for high speeds. Despite the connection speed of 833 Mbps, the wifi graph in the router shows that the maximum traffic speed was about 64 Mbps (I have 100 Mbit set in Oculus settings). But it is very sensitive to jitter.

I don’t want to buy another router, or flash permanently OpenWrt. The RouterOS is so much better…
But without fix I can’t use it with AirLink…

Check if the 866Mbps is still there in the Wireless registration table for that connection. Other busy but slow connections will slow down all other (fast) connections to their slow speed !!

MT has priority=0 (“Best Effort”) on all traffic by default. So enabling WMM uses the long “Best effort” contention window settings, the same as without WMM. Only priority 0 has A-MPDU aggregation enabled. And that’s important for the throughput: http://forum.mikrotik.com/t/help-mikrotik-capsman-wireless-download-speed-max-200mb-but-pcs-mobiles-link-speed-is-866mbps/142677/1
To set the priority, one must do it on the AP, with FW mangle rules http://forum.mikrotik.com/t/help-mikrotik-capsman-wireless-download-speed-max-200mb-but-pcs-mobiles-link-speed-is-866mbps/142677/1
