Cisco 2621XM - problem with unknown WIC card

By zromli ·
I have a problem when I plug the WIC 1B-S/T-V3 WAN Interface card into the Cisco 2621XM, the cisco will show "Unknown WIC in slot (0/0), WIC card had unknown id of 0x0". For your info, my cisco IOS is Version 12.3(6e). Got suggestion to upgrade the IOS to the minimum supported IOS (Version 12.3(10)) but I don't know where I can download the IOS version because when I want to get the IOS from Cisco website, they only can support if the Cisco unit is still got valid support warranty. my cisco router is no more support warranty. Is there any ways that I can get the IOS? Or is there any solutions rather than I need to install new IOS? For your info, I try t plug a WIC Serial card, no problem. Wait for any solutions. Thanks
