Hi ! I've replaced an 881-K9 router recently with the exact same model. The previous one was working fine until it died (no more power). So, when I installed the new one, I configured it exactly the same way as the old one. The only difference being the IOS software that is more recent on the newer one, of course. I've checked line by line and all is configured the same way as it was before.
FE0 is the lan of the SMB (all computers and printers are connected to this port from a Cisco 24 ports switch). FE1 isn't used (I use it when I need to go and plug my own laptop through this port). FE2 and FE3 have each a WAP321 attached directly to these ports. I've attached the files SH Version_Replacement (sh version result from command line) and CiscoSupport.txt (contains the configuration lines with a few xxxxxxxx to hide important information but that should not prevent help from you guys).
I created 3 vlans (as it was one the old one). Vlan2 is attached to ports FE0 and FE1. That works fine. Vlan1 and Vlan3 are attached to FE2 and FE3 (which have the WAP321 connected to it) so that people connecting to my wi-fi guest network are on vlan1 and those that do have the wi-fi password are connected to vlan3.
The problem ... vlan3 isn't working. When I ping vlan1 and vlan2, I get a response. But, vlan3 isn't responding to anything. When I look at vlan configuration, I don't see vlan3 as being enabled. So, of course, my wi-fi isn't working at all since the WAP321 (WIFICONF and WIFIMULTI) are suppose to be connected to vlan3. Of course, I've rebooted the WAP321 and 881 multiple times with no change. And, I can't connect to the WAP321 since vlan3 is not working. Like I said, I've checked line by line and the config is the same.
I need help !! Thanks !
