Recently I've tried to install modified firmware on my TP-Link MR-3220. It's a decent wifi router, in my opinion. It has a USB port so it can be connected with wireless modems. But I found some difficulties from it. Some modems I owned cannot be detected, while some other can be used, but really hard to connect with the non-bundled network provider. (The wifi router is positioned on the second floor of 3 stories building, so the wireless broadband signal is not good enough).
And then I found
OpenWRT. The aim of OpenWRT is basically to replace the stock firmware of wireless router to an open-source, linux based operating system. It even got it's own package manager (OPKG). With it, my broadband modem finally works with the MR-3220 and non-bundled internet provider.
