I run into wireless router and networking issues very often. I'd like to finally just read a book on how to trouble and diagnose problems, using tools like ifconfig, editing files like /etc/network/interfaces, and whatever. Any recommendations?
Also you may want to look at Amazon.com for books on the subject. Many times there are used books at discount price that will give you want you need.
I found a "Linux Network Administration" that normally lists for ~35USD for 12!
Hope this helps.
