is there a WIFI icon on the desktop wbar ? then select it
if not you can load it by using " tce-load -i wifi " at the terminal, then select it or type " sudo wifi.sh "
if a terminal screen appears then disappears after a few seconds then we need to see the output of " dmesg | tail -25 " copy and past that to a file and post it here, which can be a little tricky for those new to linux
one extension you might find useful is fluff a lightweight file manager install it using the same technique used earlier, while you are downloading files i'd download and copy to tce/optional directory firmware-rtlwifi.tcz and wl-r8192cu-3.8.13-tinycore.tcz be careful not to have them both loaded at the same time as they conflict with each other.
