NOTE: MX4301 means that it was sold as a single unit. MX4302 and MX4303 means they came in packages of two or three. LN1301 is just another number for the same router.

HOWEVER, if once you boot you see a WHITE/Light-Grey Linksys screen instead of a Blue one, it is of the HomeWRK variety and cannot be flashed to DD-WRT. This would be rare however.

Please open a new thread if you wish to ask any questions about this. This thread should not be a generic catch all for everything related to MX4300. It's already quite the mess and at 16 pages and makes it very difficult to comprehend or even take the time to read it all.

Disclaimer: Proceeding with anything below requires some technical know-how.

First I want to say thanks to Brainslayer and the crew for adding this router to the dd-wrt WIP list since 7/23/2024 r57538. In just 6 releases in a span of 15 days with release 8/8/2024 r57793 you have managed to get this pretty stable. I look forward to the progress in the future. Thanks for all that and more.

I have been testing this router and I will report my on going finding. The only thing I know for sure puts this in to a bootloop and resets after 5 reboots is when I try to add an EOIP tunnel. RFC 3378 EoIP.

VPN and Wireguard appear to be working. I am working on setting up a DD-WRT WG Server and DD-WRT WG Client. I currently use an RFC 3378 EOIP tunnel on 7 Asus AC5300's.

Revert To Factory Firmware The method that worked for me:
Credits to Brainslayer and Lexridge for making this possible.


enable telnet in the webif

*** Note: The wget method below requires you to setup or to have access to website. Unfortunately I could not get the wget to work using the direct linksys.com link.

telnet to you mx4300
cd /tmp
wget http://www.yourwebaddres.com/MX4300FactoryFW.img
mtd -e linux2 -f write MX4300FactoryFW.img linux2
mtd -e linux -f write MX4300FactoryFW.img linux

reboot

When it reboots if the light on top of the router is flashing red, be sure to hold the reset button on the bottom until the light turns off.

Does the USB port work on this with DD-WRT? And is it 3.0? Linksys official site said it was "for future use", i.e. not usable currently.

Yes it was working with dd-wrt. I am not sure on the usb 3.0.

Hi,

I have three of these and am interested in installing DD-WRT. Are there any instructions available, or do we need to wait for an official release? I noticed it's marked as a WIP, but some posts mention it's mostly functional.

The DD-WRT wiki for this router has been created 09.11.24. (mod edit - kp69)
https://wiki.dd-wrt.com/wiki/index.php/Linksys_MX4300

You need to download both the factory2ddwrt and webupgrade files. Flash the factory2ddwrt first, and once you reboot into dd-wrt, flash the webupdate two times. You will have a total of 3 flashes.
https://dd-wrt.com/support/other-downloads/?path=betas/2024/08-23-2024-r58124/

This ensures the latest version is installed on both partitions.

To return to stock you presently have only one choice: tty serial w/tftp.

Thank you. Didn’t know need to flash 2 more times


What about upgrade? Only flash the web grade 2 times?

You only need to initially flash once for upgrades. This insures you have keep a working version on at least one partition. If after a while you are happy with a stable version, you can optionally flash the same version to the opposite partition. Entirely up to you. I keep one version behind on one partition and move forward from there.

Does the 2nd 5G wifi work as an AP?

I tried configuring it as AP or mesh, but the configured SSID doesn't show up at all from various client.

(I remotely remember seeing it showing up back when I first setup the router, but it's gone from the 2nd day.)

The two separate 5ghz radios intentionally do not share channels. The first one that is meant for the MESH network only allows channels 36-64 while the other 5ghz radio will cover channels 100-177. This is based on other Velop tri-band Linksys routers and may not exactly match this one, but should be similar. Install a wifi scanner on a mobile device and you should be seeing both 5ghz radios and the channels they are on.

Mine just arrived this morning but it's still in the box. Haven't had time to mess with it yet.

FYI: The LAN ports are reversed on this router. I noticed this whenever I started setting up a trunk port for VLANs. They are reversed as far as the labels on the router are concerned, but in order when counting from the bottom up.
Code:
WAN  - eth0
LAN1 - eth1 (Physical Port 3)
LAN2 - eth2 (Physical Port 2)
LAN3 - eth3 (Physical Port 1)


Not a big deal, just something to be aware of.

Can anyone speak to a comparison of speeds with the OEM firmware? Are the most recent builds stable (I see they no longer ask for serial dumps).

As the OEM firmware was on my units for less than 5 minutes after booting them the first time, I cannot provide any numbers for it.

The latest DD-WRT build is very stable on this router and quite capable of sustaining its advertised speed of 1Gbps throughput (LAN<>WAN), even without using SFE/NSS.

The speeds were equivalent. DD-wrt give a lot more options though as is stable as well. Just know there is not a easy way to flashback to stock firmware currently.


It does go in to a reboot cycle if you enabled eoip tunnels if you also set your internet connection to a static ip which I intend to elaborate more on after I update to the most recent release.

I believe the boot loop on tunnels was fixed in r58163. Was not aware of the WAN static IP boot loop. To access the kernel crash logs, ssh into the router and type:
Code:
strings /dev/mtd26

and to erase it to get fresh data do:
Code:
mtd erase /dev/mtd26
reboot


EDIT: Do not run this exact same erase command on any other router. The mtd26 Oops partition is different for each device. ie. It's mtd20 on the mr7350.

You can check this by running cat /proc/mtd
Code:
# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00100000 00040000 "sbl1"
mtd1: 00100000 00040000 "mibib"
mtd2: 00080000 00040000 "bootconfig"
mtd3: 00080000 00040000 "bootconfig1"
....
mtd26: 00400000 00040000 "oops" << It's this one
