NetComm NB9WMaxxn review: NetComm NB9WMaxxn
NetComm's NB9WMaxxn could be best described as competent, and with a built-in ATA it's reasonably priced as well. Wireless performance over mid to long distance was good, and would have been excellent all round if not for its poor Intel 5100AGN results. We hope a firmware update will be issued soon to increase the compatibility.
One thing we haven't seen a lot of among the modem/routers we've been reviewing lately has been integrated analog telephone adapters (ATAs). These allow your standard phone to become Voice over IP (VoIP) capable, and NetComm's NB9WMaxxn ADSL2+ modem/router contains one such beast, offering two phone jacks and PSTN fallback. For those not familiar, this means that when your internet is out, your phone will switch back to the normal phone line as a back up — providing you have a typical voice service in addition to VoIP.
The Good
The Bad
The Bottom Line
Otherwise, the usual modem/router trappings are here, with blinky lights, a pair of sadly non-removable antennas and four 100Mb Ethernet ports.

UI and features
The NB9WMaxxn's user interface (UI) sports a different look to the 3G15Wn, and unlike the latter the wireless configuration pages load a little more snappily. Its tree menu design down the left-hand side also makes it a little easier to navigate.

As one would expect, on top of the usual features, the NB9WMaxxn has a page dedicated to VoIP settings, and other standout features include time of day restrictions down to the MAC level, and TR-069 management.
Performance
After analysing the spectrum with InSSIDer, an empty channel of either 1, 6 or 11 is chosen for 2.4GHz wireless testing. The router is restricted to the 20MHz band and will only allow 802.11n clients. If possible, the MCS is set to 15.
We use iperf to determine throughput, running eight streams, with a TCP window size of 1MB, and an interval of one second. The test is run for five minutes in three different locations, on two separate occasions. The locations are in the same room as the router, one floor down around spiral stairs and with concrete walls and floors, and two floors down under the same conditions.
The wireless throughput is tested using three chipsets, the Atheros AR5008X, Ralink RT2870 and Intel 5100AGN, then all results are averaged.
(Longer bars indicate better performance)
The NetComm doesn't put in a very strong showing with wireless at short range, but manages to do quite well at mid to long range. It should be noted that its average scores would be even better if it weren't for poor performance with the Intel 5100AGN, which consistently produced scores half of what we'd expect from 2.4GHz.
ADSL performance is simply measured by the sync speed on an Internode ADSL2+ connection to the St Leonards exchange, on Internode's very high speed profile. If the connection remains stable over a period of time, the sync speed is recorded.

Power consumption
We measured power consumption using a Jaycar mains digital power meter. It's important to note here that due to limitations of the meter, measurements are limited to values 1W and greater, and are reported in 1W increments.
The wireless radio was turned on, and an iperf test begun for measurement, using one wireless client and one wired.

Nothing exciting here, the NB9WMaxxn follows the path trodden by many modem/routers before it.
Warranty
NetComm offers a three-year warranty, but only if you register online.
Conclusion
NetComm's NB9WMaxxn could be best described as competent, and with a built-in ATA it's reasonably priced as well. Wireless performance over mid to long distance was good, and would have been excellent all round if not for its poor Intel 5100AGN results. We hope a firmware update will be issued soon to increase the compatibility.
