How To Show The uptime On A Cisco Catalyst 2950

While working on the computer shop network I had to modify the configuration on our switch which is a Cisco Catalyst 2950. After making a bunch of changes I was testing things to make sure all was working as expected however after taking a break and logging back into the 2950 it appeared that all of the changes made had been reverted. I was assuming the Catalyst 2950 had lost power briefly which means all of the changes were lost since they had not been saved to the startup config yet. To verify my assumption I needed to look at the amount of time the switch had been up however “uptime” is not a valid iOS command. Below is information on the command used to verify uptime on a Cisco Catalyst 2950.

How to Fix a Dead WRT55AG Version 2 Linksys Wireless Router

Recently I was digging in an old box of routers I have because I was looking for a wireless router to use as a secondary wireless network at my house. The secondary network needed to run WPA but be as secure as possible in every other way so my PSP could connect to it and use the Internet. I located a wrt55AG but the power would not come on and it took a moment but I finally remembered the story behind it. A friend had given me the wireless router saying the lights would not turn on after they used the incorrect plug to plug it in.

Below are the steps taken to fix the router and get it operational again to be used as a secondary wireless router at my house.
