Recently I bought a new wireless router – a Linksys WRT54GL. Interestingly, there are numerous open-source, Linux-based firmwares available for this router that unlock new features. Once can commonly hear it described as “turning a $60 router into a $600 router for free” just by upgrading the firmware.
I haven’t attempted this yet, but perhaps I will soon. Presumably, by upgrading the firmware one can boost the wireless signal, turn of SSH access, prioritize bandwidth allotment for certain computers and/or programs, and allow static DHCP, among other options.
My new router is working just fine right now with its stock firmware, but perhaps I’ll be daring and put Linux on it some weekend.
