Hi guys, i bought a cisco router today, anyhow it won’t let my add computers too my network(using Network magic ver. 4.9), It says that i need too enter my router user name and pass but since i just bought this router I didn’t set one up, Im just wondering how too set this because, none of my computers can connect .

How long are cisco certifications valid for? What happens when Cisco releases an updated CCNA cerfitification? Does cisco automatically cancel all certificates based on the old syllabus and makes it mandatory for everyone to appear for the newly updated certification? How often are updates to current certifications released?
cance_ju: Are they valid for three years from the date of becoming certified or from the date when CISCO launches the exam?
