hi all, i purchased this router and a friend flashed it with the dd-wrt firmware. he forgot to secure the connection he was done. im a total newbie, and wanted to know if someone could guide me as to how to get my wireless connection secure. since we have the dd-wrt firmware on it, i cant refer to the manual/disc, nor does it say anything anyways. it also says that it is capable of 125 mbps but im only getting 54... am i doing something wrong? thanks in advanced for any help.
