By chance, I learned there is a widely used router OS named OpenWRT. OpenWRT stands out as a powerful and flexible open-source firmware for routers and other embedded devices, allowing users to customize and enhance the functionality of their network devices.
The TP-Link TL-MR13U is a router that gained popularity for its portability and affordability. The most important feature is it contains a battery inside it. We could put it into pocket without power to provide wifi link 802.11n.
After installed OpenWRT Attitude Adjustment on the TL-MR13U, I’m happy to have the router OS replaced. It’s suitable to bring the brick in my vocation :)
