For my link archive a router I bought a few years back: [Wayback/Archive] GL-SFT1200 Secure Wi-Fi Router On The Go – AC1200 Dual-Band Gigabit Wireless Internet Router | IPv6 | USB 2.0 | MU-MIMO | 128MB RAM | Repeater Bridge | Access Point-M Mode: Amazon.de: Computer & Accessories
- It is USB-C powered (the power brick delivers 3A at 5V, but in reality it uses far less).
- Mode and reset buttons are behind the antenna (see picture below).
- It is specced as AC1200, but that’s just theoretical a number.
- It came with EU and UK plug.
I needed it because from prior experience, I knew GL.iNEt can support a special Wireless Repeater mode where it still functions as a router (hiding the LAN/WLAN behind NAT)
Two physical drawbacks likely due to the portable nature:
the plastic RJ45 ports are slightly too wide which means that these keep falling out [Wayback/Archive] Inline® Dust cover, for RJ45 socket, color: green, 100pcs. Pack: Amazon.de: Electronics & Photo- no holes in the base to hang it to a wall
One firmware drawback: it shipped with v3.212 for which I could not find release notes. Luckily the firmware v3.215 I upgraded to had: [Wayback/Archive] Firmware v3.215 is released – Technical Support – GL.iNet.
Links to product and manuals (the paper manual are just two thin sheets, but the on-line documentation is OK; I was surprised WireGuard and Tor were supported!):

I have seen too many sites where cabling was laid en never tested before actual use, which meant locating the cabling and faults was a nightmare.
Be sure to have good (which can be very simple, but more complex when Power over Ethernet is involved) testing hardware and use it during installation. You will thank yourself later.
A few videos that can be helpful:

I have been contemplating on pfSense hardware as there has been a large shortage on that market especially for having more than 2 ports (similar to for instance Mikrotik PoE router unavailability).
If by now I have not found any, I might want to revisit [Wayback/Archive] Gowin R86S mini PC offers 2.5GbE and 10GbE networking for $310 and up – CNX Software has 3 RJ45 ports and 2 SFP+ cages.
They found it via this 4 page review:

[Wayback/Archive] GS305E | Easy Smart Managed Essentials Switch | NETGEAR Support which can do many-to-one port mirroring.
This is a newer and cheaper hardware revision than the:
- GS105Ev2 (which is managed and can do port-mirroring, and is confusingly sold as GS105E-200) which in Germany already is end-of-life
- GS105Ev1 (which is unmanaged and cannot do port-mirroring and is confusingly sold as GS105E-100) which is end-of-life but still sold
Via [Wayback/Archive] Everyone Should Have One of These – EASY Packet Capture! – YouTube who explains very well why you need a switch that can do port-mirroring, then recommends the GS105E but forgets to mention:
- there are different revisions of the GS105E with the above drawbacks
- there is GS305E

I wonder how well [Wayback/Archive] H3/H2 Net Card – ODROID is supported by pfSense. It is an M.2 based PCIe network card that adds 4 ethernet ports of 2.5 gigabit each to an ODROID H2 or H3 series (so you have 6 ports total), ideal for some hefty router.
Pictures (from the above link) of the board, cases and mainboard below.
But first: Realtek NICs is not vendor supported on FreeBSD (which pfSense and OPNsense are based on).

For my link archive: [Wayback/Archive] How to send raw network packets in Python with tun/tap
I never really played around with tun and tap, so this is a nice opportunity to do so. I know they were the base for VPN on Linux, but just now I learned TUN/TAP are not available on nx, but also on Windows. Cool!

Last year, after an already long sequence of doing stupid things, Ubiquiti sued Brian Krebs.
For many this was a reason to think about what to replace their Ubiquiti.
My cloud key had already died, I never installed the USG router, so this is the reminder to see if anything has come up to replace the Unifi access points that is easy to manage in a self-hosted way are powered over ethernet, do the same seamless handover and cooperative WiFi antenna management.
Some links from back then:
