Upgrade and support for MTK MT7623 router

Hi All,
I'm thinking of buying the MTK MT7623 router (from here: https://www.aliexpress.com/item/32816965570.html), and there are few things I'm not sure about.

  1. Upgrading to the regular OpenWRT
    As I understood, the router comes with some kind of proprietary OpenWRT version, and I saw some topics about issues with upgrading it to the latest regular version (Filesystem issues?). I also saw there were few PRs about it. The information on the device page is not so clear, and looks a bit outdated.
    Can someone shed some light about the upgrade process? Can I just upgrade from the stock "proprietary" OpenWRT to the regular 20.02.1 release image from LuCi?

  2. WiFi modules
    I plan to by the version with DualBand modules (U7603E-H1 + U7612E-H1) - Are they properly supported?

  3. I saw on one topic that the support for this router is a bit neglected (F2FS is broken and how to fsck before mount on MT7623 platform?).
    Is this still the status? Should I avoid buying it?

Currently I'm using TP-Link Archer C7 v2, and my main requirements from the router are:

  • 1Gbps WAN
  • N/AC WiFi
  • VLANs and Firewall
  • OpenVPN server
  • File sharing via the USB3.0 port (SMB)
  • Dynamic DNS

Thanks,

ToH link, 1st one didn't work.

the last one looks like the one you're considering, if you google the name.

MT7623 probably won't handle gbit WAN.

As much as I like the MT7623, the unit you have in the link uses the MT76 driver (7603 and 7612). They are supported and still under development in OpenWrt, they are not the best. Since you mentioned 1Gbit WAN why don’t you look at something like this;

Keep the Archer C7 as “dump” WiFi access point and have a combination that will do “anything”. The N3450 comes with AES-NI and with 4GB ram and like 32GB msata (ssd) it wil be way more future proof (next step would be 10Gb Ethernet).

But your question: yes you should be able to do a system upgrade.

mt7623 is a rather exotic Mediatek platform (ARMv7, instead of ARMv8, as mt7622 would offer), with few supported devices and few eyes taking care of it. If a device isn't explicitly listed in OpenWrt's ToH, then there likely isn't any support for it and you'd have to develop it yourself.

1 GBit/s routing performance might be a bit much to ask for as well.

Thanks all for your comments.
Regarding the option of using N3450 and the TP-Link as access point - this might be a nice option, although I can't find the N3450 or N4200 on the ToH - where can I find information about it with OpenWRT (how to install, what is supported, etc.)?

Regarding the MT7623 being an exotic platform - is there any other similar router that is recommended for my use-case?
I can compromise on the 1Gbps WAN requirement, which is BTW not symmetric. My current ISP package is for 500Mbps download and 50Mbps download but I would like to upgrade to 1000Mbps download with 100Mbps upload.
Currently with my TP-Link I'm getting ~200-250Mbps only (as it can't do HW NAT with OpenWRT).

Thanks,

it's a plain x86, a regular PC.
