Asking is it my Cisco 891 router support wireless or not

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!

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.
