Query: worthless investment

The router portion of this device works great, and setup on a LAN is easy. However, the wireless feature fails at least 5 times per day and must be rebooted by unplugging the unit (there is no power switch). I called their technical support, and they told me to return it to the place I bought it. At least they were honest: this is a worthless investment if you want wireless capability.
