871w Wireless Setup - How To

[Paul Quintana]

Hello,

I recently got my first Cisco router for home (871w), what I want to do with it is setup wireless for it, and I don't mind if my wireless clients can browse my wired ones. I studied for my CCNA but no where does it show you how to setup wireless, you must go the wireless route as I am sure you all know.

Comcast IP is dhcp

The device ip is 172.20.0.1 255.255.255.0

ip route 0.0.0.0 0.0.0.0 f4

What I need help with:

Setting up wireless / does this device work with wpa2?

Configuring the dns server to be .1 and work, in order for my to get internet working I have to set it to Comcasts dns, and I don't want that.

Having that said I did read this artcile below and downloaded the .xls, but I have never set this up before and I wasn't sure about all the options and what was needed and uneeded, I did try the commands and it did not work.

Hi Pablo,

You should be able to set up WPA2 on 871W device depending on your IOS version. If your current IOS does not support below commands please upgrade this to highest version available.

A typical connfiguration looks as below

dot11 ssid YOURSSID

   vlan

   authentication open

   authentication key-management wpa version 2

   wpa-psk ascii

With regards to DNS configuration, i hope you want to run a dhcp scope on 871w then configuration would looks like as below.

ip dhcp pool pool1
   import all
   network   
   dns-server  Set the dns server you wanted the wireless client to use
   default-router  

Hope this helps.

Regards

Najaf

I have c870-advipservicesk9-mz.124-24.T6.bin and I don't get an option for WPA2

Also I noticed that dot11 0 by default so I turn it on, does it need to have an ip?

As for DNS I did set that DNS there but I was not getting an internet till I changed it to Comcasts DNS.

Hi Pablo,

You can use below link to verify if your IOS support WPA2

www.cisco.com/go/fn

With regards to wireless configiration usually we dont assign ip address to radio interface. Rather ip address will be on virtual interface (BVI1) as shown below.

interface Dot11Radio0

encapsulation dot1Q 1 native

no cdp enable

bridge-group 1

bridge-group 1 subscriber-loop-control

bridge-group 1 spanning-disabled

bridge-group 1 block-unknown-source

no bridge-group 1 source-learning

no bridge-group 1 unicast-flooding

!

interface Vlan1

no ip address

ip virtual-reassembly

bridge-group 1

bridge-group 1 spanning-disabled

!

interface BVI1

ip address x.x.x.x

ip nat inside

ip virtual-reassembly

Hope this helps.
