Adding OpenWrt support for Linksys MX5300

For Developers
83

Hello,

Is there some throughput data when connecting between 2 MX5300 with 5GHz radio @160 MHz bandwidth? For MX4300, it's about (iperf3) 1300 Mbps between them (radio2, 4x4 5GHz radio @80 MHz bandwidth, NSS enabled).

Hello @lytr
I am trying to do this (installing a factory image of OpenWrt 21.10 rc7 to the other partition of my MX10600 device). Can you please show me what options for the mtd command to achieve this?

TIA.

Not anymore. That link now leads to a $140 2 pack.

I tried it on mine and it seems to work. I set it to 160MHz and iw scan on my laptop shows it as 160MHz.

How do I setup vlans on the MX5300? I have vlans setup on a TP-Link TL-WDR3600 v1 on 22.03. That is using swconfig as far as I can tell based on the Luci screenshots.
MX5300 does not have the same switch menu in luci. The ToH page says it does not support DSA though.
I don't quite understand what the mx4200 page is saying. It says DSA is not supported but kind of works.
I tried setting it up like DSA in the br-lan device configuration with all ports set to VLAN 1 untagged primary from a laptop connected via wireless to the MX5300. If I apply I lose connectivity (i.e. cannot ping the router IP) and need to wait for it to auto revert. I also tried setting the lan interface to the br-lan.1 device instead of br-lan before saving and applying. I still lose connectivity when applying.

I bought mx5300 after @lytr replied and it works for me too.

I think these targets have been moved to DSA since the ToH page was written.

Anyway, VLANs work for me. My MX5300 serves as a dumb AP (with wired connection to the main router) but I don't see why it would not work if it was configured as a router. Since it's a dumb AP I added wan port to br-lan and it's the one with the wired connection to the main router. I created br-lan.1, br-lan.2, and br-lan.3 in Interfaces/Devices/br-lan under Bridge VLAN filetring. These are used as LAN, IoT lan and guest lan. One of them (the main LAN) is untagged on the WAN port and the other two are tagged (there is corresponding tagging on the main router). All three VLAN bridges are configured as 802.11q devices in the Device section of the interface. I have both wired IoT and LAN devices connected to the MX5300 so I assigned wired ports to one of these VLAN bridges. Then I created two additional interfaces for guest and iot VLANs and for each interface specified br-lan.{1,2,3} as the device. The guest and IoT interfaces are unmanaged on the dumb AP but the corresponding interfaces on the main router run a DHCP server. I created main, guest, and IoT wireless ESSIDs and assigned them to appropriate networks.

Everything works.
Hopefully, I did not forget any major steps but if I did -- I basically followed DSA VLAN howtos, so they should work for you.

Mine is setup as an AP too. I have guest as separate bridge with only wireless attached to it.
Are all your vlans untagged?
Maybe I need to do the setup over a wired connection to get everything correct before trying wireless.

92

If there are several untagged VLANs on the same port, the router won't know which VLAN the traffic belongs to and this will cause problems (at least in most cases if not always). Therefore, I believe that (additional) VLANs coexisting on the same physical port must be tagged. With that in mind here is how I configured my routers:

  1. lan1 port of the main router is connected to wan port of the AP. All VLANs share traffic over that wire. Therefore, VLAN carrying my main LAN traffic is untagged on these ports while VLANs carrying guest and iot traffic are tagged.
  2. All other ports on both routers have only one VLAN enabled. Therefore those ports are untagged.
  3. My guest VLAN only has wireless clients so it is not enabled on any physical port except the two ports in the point 1.

After trying some more, I got it to work. I must have been missing a step somewhere.

@frollic is it possible to check who added incorrect information to the description: https://openwrt.org/toh/linksys/mx5300#mtd_on_openwrt ?
There is an issue related to this: https://github.com/openwrt/openwrt/issues/21937

These two mtd erase commands should be removed from the description.

95

you can use the clock in the upper right corner to check the page history.
roll back to see when and by who the texted was added to the wiki.

mtd erase lines are gone.
