Hi, this .cfg file has been a pain in the ass. I am trying to modify my router files so it blocks ads from router. I do not want to use applications like adblock or adblockplus, I want to know how to open .cfg files and read them and edit them. When I open them with textedit, it is all random symbols, and it is non readable. I am fairly noob in this area seeking for help from anyone that can help me with this. I have tried textwrangler as well and it opens up as same as textedit.
