just receieved tp-link 300mbps wireless N nano router. Tried to getting it going on my desktop computer running latest version of Mint Linux, just installed. Plugged into NIC, light is solid green.  When i type http://tplinkwifi.net or 192.68.0.1 into browser, it can't find the device. The connection icon shows up on the task bar with an 'x'. If I click on it and go into network settings, wired security , the default authentication defaults to MD5, then I specify the username/pw supplied with the product, still no dice. I tried it on my windows10 laptop and had it set up in a couple of minutes, so I know the device works.
