Billion releases a somewhat daunting, but powerful modem-router.
Billion has earned its reputation as a heavy hitter in the networking market through its focus on delivering great price/performance for educated users, a marked difference from the push towards simplification occuring with other manufacturers. The 7800NXL bears all the hallmarks of this, supporting a raft of connection options, from USB-mounted 3G/4G dongles, cable/fibre connections through a gigabit WAN port, and a built in ADSL 2+ modem.
The only real weak point is that it only supports 2.4GHz 802.11b/g/n Wi-Fi, which means that, while all your devices will happily connect to it, the signal is more subject to interference than something operating over the 5GHz band. This is, of course, moot if you only use 2.4GHz Wi-Fi devices, but 5GHz is increasingly common, and a simultaneous dual band product is near mandatory for serious Wi-Fi users. As long as you are aware of this limitation, though, the 7800NXL is an excellent offering, one that may be somewhat daunting for the less tech-savvy type, but certainly delivers for those who love tweaking settings.
