Adding support for Mercusys MR90X

Is anyone else seeing dropouts with this?
I have a 1000/115 FTTP PPPoE connection.
Every other day this drops out, my Netgear WAX206 on the other hand is rock solid.
My ONT is 2.5GB, so full uplink is being seen.

Does Hardware NAT/Software offloading works for this device?

I am experiencing this issue randomly, where the ethernet switch crashes and does not come back up. Is that what you mean?

I have tried using lan0 as WAN, instead of eth1 (the 2.5g port) but that didn't solve it, am now testing with tso disabled (ethtool -K eth0 tso off), will see how that goes.

Running openwrt 23.05.4

Mine was an ISP issue.
I'm running SNAPSHOTS at present as 23.05.4 looks quite buggy.

I have an issue where setting any channel upwards on 48 results in the 5ghz network failing to start, for clarification my country allows quite a lot of channels above 48. This was working fine with my older router that also had openwrt where I had channel set to 136-144ish.

Similarly changing width to 160mhz also disables the 5ghz network regardless of channel set. Is anyone else having similar issues?

Another issue I have is slow 2.4ghz speeds. 2.4 ghz speeds are great before I add a 5ghz network access point, at which point they drop to very low speeds around 40mbps right next to the router, before adding the 5ghz one I was getting 150 mbps right next to the router.

what release are you running?

I saw your post about the snapshot and updated to that, the channel thing is fixed but the 2.4 ghz issue continues sadly. 160mhz also does not work, but that is probably due to interference.

just enabled 160mhz on mine, set to auto, picked up channel 100.

Can you post your 2.4ghz settings?

Here it is, It seems to be hard capped to 50 up and down for some reason... I have also tried with option ieee80211w '0' and '1'.

Any reason you do not have your country set?

I have it set, just removed it because I didn't want to share. I don't believe this would affect it, point remains that I am paying for 500 up and down and getting 50 at the 2.4 ghz band standing next to the router, this wasn't the case with the original firmware and before I had set up the 5ghz band in openwrt.

Okay, I pay for 330/50.
Seeing 124/48 on my 2.4ghz only.

Recently bought a Mercusys MR90X, tried to install openwrt via ssh and telnet, but looks liked i messed up some env variables and router bricked.
Never had a solding experience, but tried to debrick the router using uart method.
I soldered the jumpers and attached UART. Finally, I got some output from the router in serial console, but it never accepted my input.

What could go wrong and are there any other options I can try to debrick the device? Thanks

What about the recovery boot mode "turning on while pressed reset button?

https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=e4fe3097ef6a961874b66932a0ac4be18070630a

Recovery
--------
1. Press Reset button and power on the router
2. Navigate to U-Boot recovery web server (http://192.168.1.1/) and upload the OEM firmware

Recovery web server opens, but uploading OEM firmware does nothing

Try connect the cable to another LAN port.

Hi,

Excuse me my rookie question, is it possible to change the MAC Address and BSSID Address in Openwrt?

Does this Openwrt have all the original firmware functions such as OpenVPN and Mimo 4x4?

Sure. You can change it or set up random MACs.

MIMO 4x4 works. OpenWrt has no OpenVPN package installed by default. You can install it either manually (using OpenWrt package manager) or embed it to the image here - https://firmware-selector.openwrt.org.
