Finally! I can almost rejoice for the general consumer! The setup wizard for the TEW-673GRU asks you to change your admin password as part of the setup. This has been a very long time in getting here, but it is nice to finally see it.
Chose the time zone you are in right after you make sure you change your password from the default one that anyone can find out.
Next up, you can change the LAN and DHCP settings.
TRENDnet has included quite a few options for your WAN connectivity type.
If you chose dynamic IP you also have the option to clone or set a new MAC address. This helps with certain ISPs that run MAC filtering on their DHCP systems.
You can also setup both bands for wireless connectivity. Unfortunately you cannot setup the security for them from the Wizard. That has to be done in the regular Web UI.
The setup wizard on the TEW-673GRU is almost a complete one. If they would have added in security setup for the wireless (both bands), this would have been the best wizard I have seen on a consumer product.
