Hi masters,
I have these 891 routers and I wonder do they have a Dot11 wireless or not?
I issued a command show ip interface brief the result is here:
R1#show ip int br
Interface IP-Address OK? Method Status Protocol
Async1 unassigned YES unset down down
FastEthernet0 unassigned YES unset down down
FastEthernet1 unassigned YES unset down down
FastEthernet2 unassigned YES unset down down
FastEthernet3 unassigned YES unset down down
FastEthernet4 unassigned YES unset down down
FastEthernet5 unassigned YES unset down down
FastEthernet6 unassigned YES unset down down
FastEthernet7 unassigned YES unset up up
FastEthernet8 unassigned YES unset administratively down down
GigabitEthernet0 unassigned YES unset down down
Vlan1 10.10.10.1 YES NVRAM up up
There nothing show like Dot11Radio0 on the list. It means there is none wireless interface.
But why in my front-case there are LEDs that have label 2.4 GHZ WLAN and 5 GHZ WLAN?
1. Do my router support wireless or not?
2. If the router support wireless, what I am missing to be able to configure my wireless Dot11 radio interface?
Thanks a lot!

Hello,
This is my show inventory output Sir.

Hi,
Sorry
PID: CISCO891-K9
As you can see there is no "W" in your router PID so it can support Wireless

Does the C891F-K9 support Wireless and SFP? I need a router for my home office. My Internet termination is a SC for fiber. I haven't bought the router

Hello,
both the 891F and the 897VA have an SFP port, and support wireless. Check Table 2 in the document linked below:

Thank you so much, the 2Ghz and 5Ghz threw me off as well. My one is not wireless after I looked at the inventory.
