Workaround

I need to disable and re-enable WiFi on my phone before running adb connect on my computer. Then I can both ping, telnet, and adb connect to the phone.

The problem with me for my Samsung Tab 1 was an adb process was already running on port 5037 on my Xubuntu 14.04 machine, which I was unaware about until I typed pgrep -l -u username. To fix this, I terminated the adb process using pkill adb, navigated to my platform tools folder and ran adb tcpip 5037 and then connected to my device using the 5037 port number. Boom! Worked like a charm.
