This is a good value ADSL2+ modem/router, with one of the more user friendly setup processes we've tested.
The Web interface is clean and intuitive, and connecting to our iiNet account using the QuickStart feature only required us to enter our login details; the Bipac 7300N pretty much does the rest itself.
As an ADSL2+ modem it's capable of downloading at a theoretical maximum speed of 24Mb/s and uploading at 1Mb/s, but it also supports Annex M for faster upload speeds, as long as your DSLAM and plan support it.
Of course the Billion Bipac 7300N will also function solely as a router and as an added bonus one of the four Ethernet ports doubles as a WAN port, which can be used to connect a cable modem.
Among the settings you'll find a Firewall with everything from MAC address filtering to keyword filtering, QoS scheduling and virtual server functions. Wireless security includes all the obligatory options such as WEP, WPA/WPA2 and Wi-Fi Protected Setup (WPS) for those with WPS devices.
The three detachable aerials provided good signal strength up close, but once we increased the distance for our performance testing, we got mixed wireless results.
At 2m range the 7300N averaged 45Mb/s and streaming 1080p video was smooth, with no visual or audible hiccups. At 10m, with minor obstructions added, the speeds dropped to 35.16Mb/s, but the video stream remained smooth and watchable. In our long distance test, at around 40 metres with multiple obstructions, the Bipac 7300N was completely ineffectual.
The only way we could get any signal was by setting up the notebook with direct line of sight to the router, at which point we got speeds of 4.56Mb/s. The video stream became unwatchable at this stage. Given the performance of most routers in our last group test (web ID: 121311), this is unacceptably poor.
The Billion Bipac 7300N is an easy to use ADSL2+ modem and wireless N router with fair wireless speeds. However, obstructions are not your friend, as this value-for-money modem/router slows where interrupted. It's worthwhile if you're in an apartment or small house, but those with McMansions should try another brand.
