Wireless testing results are highly dependent on the methods used, but, more importantly, on the environment that they are tested in. Since test environments differ from reviewer to reviewer, results can vary.
I don't think you can take any one site, including SmallNetBuilder as gospel when it comes to wireless product selection. It's just one more data point in a decision process that's not straightforward.
We ran our tests on the original version (V1) WRT610N. That could account for some of the difference in results. But the caveats above still apply.
It's good info you can only do so much here. Like you said prior under EnGenius you don't do continuous testing (stress I guess you mean plus adding firmware updates) The other site just goes by results from others around the net. Seems more geared for Fon Fonera 2.0n which is 10/100 router. Then the rest follows.
This is how that site rates
Cisco Linksys WRT610n. 57%
Pros
gigabit wired ports
wireless N offers extended range and a huge speed boost
attractive look, good for exposed routers - no external antennas
Cons
expensive
most consumers don't require the enhanced speed
Firmware MUST be upgraded to latest available to avoid connection problems
Cisco Linksys E3000 High-Performance Wireless-N 72%
Pros
true dual-band for the best performance, capable of broadcasting to older 802.11G 2.4GHz devices simultaneously without slowing down true 802.11N devices
NAS functionality
wall mountable
Cons
no support for non-network-enabled (USB only) printers
poor media server
not compatible with custom Linux based firmwares
Netgear WNDR3700 87%
Pros
Gigabit and true dual band wireless-n for fast transfers
dual network support - create a second wireless network that is locked down for guests, or one dedicated for streaming media only
slick aesthetic
Cons
does not support plugging in a printer
storage performance is poor
high price for speed not capable or required by the majority of consumers
But Tim they don't go as far as you in actual testing the wireless, up and down, LAN to WAN and the WAN to LAN plus you show the internals and keep up the charts. THW site pretty much like this site above except some pro and cons. Every site going to show which router can do what?
They even got:
DD-WRT 71%
Pros
Can give $60 routers features of $600 routers
Very large database of compatible hardware
Huge community, lots of support information
Many useful features for network administrators
Cons
Can be tricky to install--not for all users or the faint-of-heart
Has the potential to brick a router
