GL.iNet 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

Posted by jpluimers on 2025/12/09

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)

connection method

Two physical drawbacks likely due to the portable nature:

  1. 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
  2. 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!):

Do WiFi-cables (German: WLAN-Kabel) exist?

Posted by jpluimers on 2025/11/21

There is this German joke about “WLAN-Kabel” (WiFi-cable) ** that goes with (Germans mocking about Internet and technology still being uncharted territory*).

Yes, they do!

SwiftOnSecurity on X: “Fun Fact: Your WiFi access point needs to know what country it’s in because of law about specific radio powers and channels and other functionality. It can be super-complicated! For example, DFS detects radar pulses and switches frequency for safety.”

Posted by jpluimers on 2025/04/07

Not just for safety: if you keep blasting your WiFi radio at frequencies used by weather radar, you are highly visible on the weather map causing predictions to fail.

If you thought you found cheap directional WiFi antennas (2.4GHz or 5Ghz), then think twice

Reminder to self: mid-term solution for replacing Ubiquiti access points

Posted by jpluimers on 2023/12/11

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:

NeverSSL – helping you get online on WiFi networks requiring authentication

Posted by jpluimers on 2023/07/07

[Wayback/Archive] NeverSSL – helping you get online.

What?

This website is for when you try to open Facebook, Google, Amazon, etc on a wifi network, and nothing happens. Type “http://neverssl.com” into your browser’s url bar, and you’ll be able to log on.

How?

neverssl.com will never use SSL (also known as TLS). No encryption, no strong authentication, no HSTS, no HTTP/2.0, just plain old unencrypted HTTP and forever stuck in the dark ages of internet security.

While writing it in 2022, the site would redirect me to http://oldserenewonderousbirds.neverssl.com/online, http://beautifulgrandoldspell.neverssl.com/online and http://majesticsilveroldeclipse.neverssl.com/online, which will change probably each time to deter DNS caching, as per this message when I disabled JavaScript:

⚠️ JavaScript appears to be disabled. NeverSSL’s cache-busting works better if you enable JavaScript for neverssl.com.

Why NeverSSL

Because NeverSSL always uses plain unencrypted HTTP traffic, any captive portal WiFi or wired network can easily sneak in or redirect to authentication.

That way you can logon, after which you can use encrypted HTTPS/SSL/TLS/HSTS traffic.

Via

DNS hijacking can be used too

Leading to the above was this post by b0rk: [Wayback/Archive] how airports lie to you with DNS.

If you want to connect to Twitter contacts on Mastodon, be quick: the new Twitter API changes might also break Mastodon discovery tools in a day or so. Run hemem before it’s too late!

If you are on Mastodon as well as Twitter, then run these tools today, as soon they will likely stop working:
