Dave Modem Getting CCNA certified Nov 1, 2026 12:24 am

Studying for the Cisco CCNA exam. Using Packet Tracer for practice labs. The subnetting math is the hardest part.

I wish I had known this sooner. Would have saved me a lot of trouble.

Tried three different approaches before this one worked. Persistence pays off.

Honestly this should be in the FAQ. Beginners ask this every single week.

Adding one tip: make sure you double-check everything before you start. Trust me.

Grace Tanaka WiFi range extension tips Aug 18, 2026 7:24 pm

My WiFi doesnt reach the bedroom. Got a Linksys WRE54G range extender for $50. Full signal everywhere now.

Disagree respectfully. In my experience the opposite is true.

My experience: it depends on your specific situation but generally this is good advice.

Eve Packet Home network security basics Jul 26, 2026 3:24 pm

Change your router default password! Enable WPA (not WEP). Disable SSID broadcast. Use MAC filtering. Basic but effective.
