Three times in a row, their router gave me a DHCP address on reboot, and approximately one hour later, refused to accept any packets, including pings, new DHCP requests, and attempts to access the configuration http server. Reboot again is the only way to get back online.
Their tech support is just like Microsoft: Unplug, cycle power, reboot, .... Except that Microsoft uses phone lines that don't cut out and techs that can understand my English.
Next, I am unable to call the number they gave me. Their tech was unable to accept my explanation that a firewall IN THE COMPUTER is not able to keep the adapter upstream from talking to their server.
Audio quality was OK, except that about ten times in a fifteen minute call it snipped about one second of audio from the conversation.
I'm sending it back.
