Hands Down, Best Router within 100$: K3C (which costs 30 USD)

Since I need a router to turn the printer (gift from Jingbo) into a internet printer, I did some research on cheap-but-powerful routers.

K3C costs about 30$ but performs like a 200$ router.

Upgrading to the un-official firearm is highly recommended, which unlocks tons of features, including Ads-blocking, USB-printer, etc.

A nice tutorial is available in Chinese. However, no available tutorial is for K3C-international (i.e., can be brought from U.S.). After some tiny-little explorations, I successfully finished the upgrade. Here are some notes based on my experience:

  • upgrading to unofficial versions is risky; all operations are at your own risk;
  • the version number of international-K3C firearm is in a different serial (from the tutorial), so ignore all version information in the tutorial;
  • update the official firearm to the latest version, and then do the upgrade (I did this and it worked for me);
  • after upgrade to unofficial 1.1, please go ahead and upgrade to unofficial 1.6 (1.7 is not very stable and not recommended);
  • you need a windows pc for the upgrade… (based on the tutorial);
  • some links in the tutorial page is outdated, please find the files as below:
