I have a pair of Aironet 1400's that have been up and running for about 5 years now. Week before last, and now this morning, one of the bridges inexplicably went offline, couldn't be connected or telnetted to, and wasn't pingable. It happned twice, almost 24 hours apart, and then was fine all of last week, and now again this morning. In all cases, power-cycling brought the bridge back on line and operational.
What is the life expectancy of one of these bridges? I have no idea even where to begin troubleshooting this issue.
Any feedback would be appreciated.
