Performance on Linksys EA6350 v3

Hi Everyone,

New to the forum so apologies if this is the wrong place to post.

Just wondering if anyone has any experience with the Linksys EA6350 V3 and OpenWRT? I'm running 3 of them as I got them cheap. LAN>LAN is top notch, no issues there, however, 5Ghz > LAN is a little slow for my liking, maxing out at just below 300mbps. Doesn't look like a CPU issues as no cores are being pushed that much whilst stressing the WiFi.

If anyone has any ideas, it would be much appreciated.

Around 350 MBit/s would be reasonable (under good circumstances, so same room, little interference), around 300 MBit/s would not be that far off (especially if you'd be in a densely populated area).

Ahh I see, to be fair to it, its actually behind 3 walls albeit timber-framed house. Decided to mess around and upped the channel width to 80Mhz instead of 40 and got this:

UPDATE: Thought I should update this post regarding speeds - was getting conflicting reports that this device can do over 600mbps over 5GHz using Openwrt so decided to do some testing.

Turns out packet steering doesn't function as it should - under 5GHz WiFi load, max speed is around 300mbps with all usage on Core 0 (packet steering on)

Solution is to manually install IRQbalance, edit the config file to enable it and start the service. With this, I'm not getting speed of around 550mbps over 5GHz. I used this in conjunction with packet steering (seems packet steering makes a very subtle difference in speed)

I use one as an AP/switch, inside a wood cabinet with the door closed. Here's an example of what I get on an old Macbook Air on 5GHz from 3-4 metres away. 80MHz, WPA2-PSK, 802.11r Fast Transition enabled, irqbalance enabled.
