I have 2 Cisco Aironet 130 series wireless bridges that are connected. Once or sometimes twice a day I must power cycle (Cisco Bridge1). Cisco Bridge 2 never has any problems. I have went through and checked all settings and verified the settings were the same. The clocks were never set until yesterday. I noticed today after my power cycle and ability to access it that the time went back to 2002/2/28. Is this a battery problem? Can anyone give me some help?
