The slot is wired for PCIe only. It is not suitable for most LTE modems since they require a USB bus.

I was thinking more replacing the pcie card with mt76 devices.

Just got the MX60W and a little annoyed to see that all 4 LAN ports appear to be on what appears to be a swconfig switch, without lan1, lan2... interfaces. Can this target use DSA?
Think the answer is this PR https://github.com/openwrt/openwrt/pull/14037
That's me. Faster iperf. No idea about switching.
Thanks for the contribution. Seems to work great for my use case - using DSA to run as a regular switch. I noticed a couple of boot errors during Ethernet bring-up after building your branch for my MX60 but once booted the code seemed good.
One of them should be fixed in the next push.
The other one is a PPC kernel issue that's mostly harmless.

When installing openwrt on Cisco Meraki MX60 I failed even though I followed all the instructions on the wiki page. Even though I repeated the installation process several times.
First of all, when I execute the commands as in point 5 of the directive here
It return with these errors.
root@OpenWrt:/# ubirmvol /dev/ubi0 -N part1
ubirmvol: error!: cannot find UBI volume "part1"
error 2 (No such file or directory)
root@OpenWrt:/# ubirmvol /dev/ubi0 -N part2
ubirmvol: error!: cannot find UBI volume "part2"
error 2 (No such file or directory)
root@OpenWrt:/# ubirmvol /dev/ubi0 -N storage
ubirmvol: error!: cannot find UBI volume "storage"
error 2 (No such file or directory)
Cannot find part1, part2 and storage partitions in UBI.
When I look at which sections are in UBI, I get the following output

If I somehow ignore these errors and do squashfs-sysupgrade upgrade after booting with initramfs, I keep getting the recovery mode page.

Is there anybody help me?
I think I had the same error. I read the output of ubinfo and (after backing up all blocks via the initramfs live image to my computer) I decided that the likely ubi volumes from the old OS were the ones labelled kernel, rootfs recovery and rootfs_data and those were probably not needed so I removed those.
Then I was able to create a new recovery ubi volume with the initramfs for recovery and run the sysupgrade.

Hello, just to say I had the same problem. Solved it by using an old firmware combination, whuch uses "tar" file extention for sysupgrade file. I used "openwrt-18.06.4-apm821xx-nand-meraki_mx60-squashfs-sysupgrade.tar" . for "openwrt-18.06.4-apm821xx-nand-meraki_mx60-initramfs-kernel.bin". Worked like a charm. Before that I tried number of newer versions, where sysupgrade has a bin extention and always booting from the newly flashed sysupgrade.bin failed with something like: xz decompression failed". It seems to me, that MX60W has a problem to decompress in right manner the sysupgrade.bin file and write it down as new firmware. I noticed, that if you take the sysupgrade.bin file in 7zip windows program and unzip it, you see three files: CONTROL. Kernel and Root. Than you could add them to an archive with "tar" extention. Thus you will get a sysupgrade.tar archive file, instead of sysupgrade.bin compressed archive. You may try to use it for upgrade. I haven't tryed this yet, because my router works just fine with the old firmware. Please set us know if this worked, if you would try it. Cheers.
Thank you so much for sharing your experience. I wish you had shared this suggestion 1 month ago 
I think I broke the device while tinkering to find a solution and I am sure I need a nand programmer to recover it. I may ask for help again as soon as I solve this problem
I am so sorry your device broke down. What are the sympthoms? Doesn't boot when powered? Hope you fix it, or even find one cheap on ebay. I will be happy to help with openwrt flashing. Cheers.
Just FYI to both posters @Miro1 and @asuz. The original instructions required a serial cable. Have you checked the output of the bootloader?
Hello, is there anybody have full dump of the nand ? I mess it up and need to reprogram
This user may have one readily available:
@asuz I believe that the u-boot of meraki mx60 is enough for you:
This is gzipped u-boot region of meraki mx60, with sha256 0d2b18e693a396240ab75f9b81f1cf5bba36515a4f87812bdba58674d076e823 meraki-mx60-u-boot.rom.gz

This time, I broke my own record and rendered the device unusable, so I think the only solution is to reprogram the nand. I can't even access uboot from console pins.
