I have got en WRT54G v3.1 router with the latest dd-wrt v2R2 on it. After changing my password from admin tot something else (with or without numbers doesn't matter...) there seems to be an very strange language used on the router. Here is a printscreen: Most of the word in the configurething of the router seems to use this strange language. Only by putting a back-up back it becomes normal. But I wan't to change my password; What is going on?
