I use the VPN to connect back to my home network to reach internal devices and services when I’m out and about. The router runs the RouterOS operating system, which supports WireGuard, a modern VPN protocol. I wasted several afternoons and late evenings but didn’t manage to set it up. It would turn out that a bug caused all my hardship in the MikroTik web configuration interface.</p> <p><a href="https://www.ctrl.blog/entry/routeros-wireguard-peer-bug.html">Read more …</a></p> urn:uuid:411d5307-7d8f-4581-b275-e63be128dc69 2022-10-15T12:23:00Z 2022-10-15T12:23:00Z TP-Link network equipment hijacks some DNS requests No one remembers the IP address of their favorite websites. Why should you remember your router’s IP address? TP-Link hijacks DNS to give itself a domain name. <p>TP-Link network products — including Wi-Fi routers, repeaters, and access points (AP) — use deep packet inspection (DPI) to intercept specific domain name system (DNS) requests. Each product looks for one or two domain names and will hijack the request to issue a local response containing its own internet protocol (IP) address.</p> <p><a href="https://www.ctrl.blog/entry/tplink-dns-hijacking.html">Read more …</a></p> urn:uuid:0e9c97b8-9661-4c7d-a923-1634b0cb23d5 2022-10-05T14:23:00Z 2022-10-05T14:23:00Z A closer look at Steam’s local network cache proxying protocol Valve Software has introduced a new automatic method for caching game downloads on a local proxy server without needing to reconfigure individual Steam clients. <p>There’s no need to waste family game-night time waiting for the same Steam game to download over the internet! All you need is a local caching proxy server. Repeated downloads from a local cache are faster, and you free up your internet bandwidth for other things (like downloading other games). Steam clients will even auto-discover and self-configure to use your local cache.</p> <p><a href="https://www.ctrl.blog/entry/steam-lancache-protocol.html">Read more …</a></p> urn:uuid:c4e5ee2d-3514-42bb-a27e-2760b2f37758 2022-09-04T14:01:00Z 2022-09-04T14:01:00Z TP-Link band-steers 2,4 to 5 GHz Wi-Fi even when the radio is off TP-Link Wi-Fi access points mindlessly band-steer clients off 2,4 GHz to the 5 GHz radio; even during periods when the 5 GHz radio is powered off. <p>My TP-Link EAP653 (available on Amazon) Wi-Fi access point (AP) has some features that don’t work well together. Who would have thought that its proprietary extensions to the Wi-Fi standard would cause compatibility issues with clients?</p> <p><a href="https://www.ctrl.blog/entry/tplink-band-steering.html">Read more …</a></p> urn:uuid:fd01bf1b-cc6d-47bb-9045-f2015a5e5f4d 2022-08-02T07:25:00Z 2022-08-02T07:25:00Z “Gigabit Router” doesn’t mean it can deliver gigabit internet speed Make sure you buy a network router that can fully exploit your gigabit internet connection. Many routers say gigabit on the box, but doesn’t deliver gigabit speed. <p>Most manufacturers of consumer-grade network routers (both Ethernet and Wi-Fi) brand their products as “Gigabit Routers”. At the very least, it’ll say “Gigabit Ethernet”. However, neither term necessarily means the router can fully exploit your gigabit internet connection.</p> <p><a href="https://www.ctrl.blog/entry/gigabit-router.html">Read more …</a></p>
