Thank you for the guide, I have already followed these steps previously and already switched over to Router mode through LAN cable.

I am not that excited about the network transfer speed though, I recieved a 20MB/s maximum at all times through to an SSD. This is with and without the interference option toggled.

I suppose that concludes my hope for gaining faster speeds. And will have to try my luck buying a NAS I suppose.

Thanks any way!

Hi, given some issues and an unknown one which left my security camera dead, I switched back to AP mode, so unfortunately screenshots won't be possible.

I have the AX50 set up behind my ISP modem, the PCs I transfer from/to are cabled up using fresh Gigabit Cat 6 cables (re-did everything a while ago)

As for storage I used a HDD dock capable of doing USB 3.0 speeds, which I have tested by plugging it into my PC directly. Inside is a new 256 GB SSD straight from the box. Gives me roughly 5-6 times the speed this router will get me on file transfers. Lets say it is at least 100+ MB/s.

As for the option, going to advanced settings you can go to System Parameters, and then there is a toggle "Reduce usb 3.0 interference", with a warning it may reduce wifi speeds. Going into AP mode removes your ability to set or see said function.. Which is a bit weird but I can understand AP mode needing to be super easy.

With and without this option I am maxed out at 20 MB/s. Which makes for a painfully long waiting time. No other settings seem to have had any result.

I know the SSD+Dock work, I have since posting this taken the HDD dock up and plugged it into my Server directly, allowing full gigabit transfer speeds.

In all honesty, it may have been my expectations that have ruined the 'NAS Capability' of this router, I really like how simple it was to set up. But at 20MB/s the speed is much slower than even a 6 hear old harddrive would be capable of. Making transferring any large files to just be annoying and very slow.

Oh and additionally, this was all set up without using the WAN port at the time. Router was in router mode with its LAN added to the network so I can reach both. Not sure if that would affect anything but may be useful to know any way.

If you have any more questions, or do need that screenshot just let me know and I'll do my best to come back with whatever you need.
