My budget is max. around 400€. I found out gL-Inet Spitx AX as a good device since it pre-installed OpenWRT. It doesnt support WiFi6E, but it is ok. However, it is still in pre-order phase. Can anyone recommend another router?
This is incorrect, the device is not supported by OpenWrt™ so far at all.
They wrote it on the website: https://www.gl-inet.com/products/gl-x3000/#pre-order:
Runs on OpenWrt 21.02 (Kernel version 5.4)
Spitz AX runs on GL.iNet's latest SDK4.0+ firmware and presents a user-friendly interface for common users to set up the router with minimal inputs, and an extended customization experience for advanced users to install plug-ins and applications. Spitz AX runs on GL.iNet's proprietary firmware based on OpenWrt (v21.02 Kernel version 5.4), supporting more than 5,000 ready-made plug-ins for customization
Their private variant.
Emphasis mine, in other words 'not OpenWrt at all' - neither the device, nor the underlying SOC, are supported by OpenWrt at this point.
Ahh ok, thank you guys for pointing out that they use their proprietary one.
You might consider looking into a WiFi 6E router and an LTE dongle or a system with a mPCIe slot for an LTE module.
I did a search for capable, affordable and available LTE routers two months ago and I wasn't very successful. None of the devices I found meet your requirements of WiFi 6E (not even WiFi 6).
- The TP-Link MR600v2 is an option (only WiFi 5), but you need a patch and need to build your own snapshot image. I had it for two weeks before selling it again.
- The ZyXEL NR7101 seems to be a good option regarding 5G connectivity, but as an outdoor solution it only has 2.4G WiFi. Way too expensive.
In the end, I explored some new devices:
- old Alcatel HH40V - very bad WiFi and terrible OEM software, working now with OpenWrt but more out of curiosity
- ZTE MF282 aka DreiTube (provider branded); working fine, but only WiFi 5; makes a nice AP because of the design.
- ZTE MF287+ aka DreiNeo (provider branded); relatively capable CPU and LTE modem, but again only WiFi 5
Thanks @andyboeh for mentioning some devices! But the ZTE router is not easy to find online.
I found out OrangePi 5B https://www.amazon.com/dp/B0BZ4BTLXS, which is quite new.
How difficult is it to configure and build OpenWrt for that board? It has the same processor as Nanopi R6S.
