Although it's not essential for now, at least in the US, the E4200 doesn't support IPv6.
The E4200 comes with a CD that installs Cisco Connect. This setup and management software first appeared in the Valet models' USB Easy Setup Key, but is now shipped on CD with all Linksys routers. Craig covered the Easy Setup / Cisco Connect features pretty well in the M10 review, so I won't repeat them here.
In the E3000, you had to use Cisco Connect to access the wireless Guest Access and Parental control features. But in the E4200, you can get at both via the web interface. Figure 5 shows the Guest Access screen, which enables access for the 2.4 GHz radio only.

I also installed and checked Cisco Connect, but it has the same limitation. Guest access is Internet only and "guests" can't see each other, either.
Parental Controls now can also be set from the browser. But it looks like Cisco has omitted the automatic age-specific web-filtering offered in the Valet series. The E4200's Parental Controls only allow up to eight URLs to be blocked for up to five computers / devices along with setting Internet access windows (Figure 6).

If you need finer control, then you can switch to using the Internet Access Policy controls shown in Figure 7. This mode also allows you to set access times and URL blocking (only four URLs), but also enables blocking of specific web applications by port.

Moving on to wireless features, the E4200 defaults to 20 MHz bandwidth mode for both the 2.4 and 5 GHz band radios and to using Wi-Fi Protected Setup (WPS) for automatic wireless setup. If you switch to manual mode, you'll see the settings shown in Figure 8.
Figure 8: Basic Wireless settings
Other 5 GHz radio modes are A-only, N-only and disabled, while the G radio modes are B/G only, B only, G only, N only and disabled.
Channel selection defaults to automatic for both bands and Channel Width to 20 MHz only. Channel width can be set to Auto (20 / 40 MHz) or forced to 40 MHz for the 5 GHz radio, but only Auto (20 / 40 MHz) for 2.4 GHz.
If you don't like the wireless controls seen here, that's too bad. Apparently part of designing a "Maximum Performance" router includes not letting you futz with controls like those the E3000 provides (Figure 9).

Don't go looking for WDS bridging / repeating, AP mode or scheduled wireless enable / disable, either. There is also not a physical radio on/off switch.
