The 424 places among the top routers with 100 Mbps WAN connections in our Router Charts with down and uplink throughput of 93 and 92 Mbps respectively. Figure 14 shows the IxChariot plot with nicely matched and stable throughput in both directions with 126 Mbps total throughput.

The main disappointment will be for P2P users, since I was able to get only 96 simultaneous connections to successfully complete the one minute test, and even that took the maximum three attempts.
I didn't do any wireless testing on the 424. But I wouldn't expect miracles from its 802.11b/g radio that lacks any proprietary throughput enhancement options.
The MI424WR has enough speed to handle the fastest Verizon FiOS 30 Mbps down / 5 Mbps up service with throughput to spare. Its feature set is extensive, but can be hard to access through a user interface that's easy to get lost in and frequently annoying with its ineffective warning/nag screens. However, its firewall port forwarding and filtering features will handle just about any scenario that you could want and you get QoS controls, too.
Its main disappointment will be to P2P fans who want to use all that bandwidth as a bigger straw to suck down jumbo-sized media files. The Parental Controls also leave a lot to be desired since they can be easily bypassed and don't properly log attempts to access blocked sites. I also wish that I could have seen how MoCA networking performed. But that will have to wait for another day.
