Actually, I perform the same procedual by DSL (Not DSL-N) but ehe keyboard lock-up after bring up network card by ifconfig wlan0 up, it may cause by the 4K stack problem (i don't know how to solve by Damn Small Linux), so I give up trying DSL (Althought I thought it is better) and use DSL-N instead.
