Wireless Access with Cisco 877W Wireless Router

Welcome to the world of Cisco!

Of course, trying to configure a new Cisco router from scratch can be slightly daunting at first.  But, once you get used to the configuration, can be relatively simple to maintain and configure.

I would suggest starting with the following Quick Guide link to get the 877W up and running.  

http://www.cisco.com/en/US/docs/routers/access/800/850/software/configuration/guide/857sg_bk.pdf

Additionally, you might need to consult your ISP for additional information on integrating the router with your ADSL line.  They might even have an additional walkthrough available for their network specifics.

Hope this helps - and good luck!

Hi there is a sample config for you:

http://exewiki.exetel.com.au/index.php?title=Sample_Config_For_Cisco_877

ikalmar

Thanks for getting back to me.
Just a few questions (quite emabarrassing).

In the sample config below, can someone tell me where I would get the hostname from? Can I use the IP address of the computer that I trying to connect from?

Also, I'm currently using netgear and whenever I use netgear to access the internet I'm never asked for my ADSL LOGIN PASSWORD. However, when configuring the dialer interface I have to input my 'chap password'. Don't understand why I need to include the chap password when configuring the cisco 877W, see below. Any suggestions?


interface Dialer1

description eXeTeL-Network

ip address negotiated

no ip redirects

no ip unreachables

no ip proxy-arp

ip nat outside

ip virtual-reassembly

encapsulation ppp

no ip mroute-cache

dialer pool 3

dialer-group 1

no keepalive

no cdp enable

ppp authentication chap callin

ppp chap hostname xxxxxxxxxx

ppp chap password *******TYPE YOUR ADSL LOGIN PASSWORD HERE*******

!
Cheers

Guys,

I thought I would use authentication PAP just to get the cisco 877W working. Can some please take a quick look at the configs and let me know where I'm going wrong....

Hi,

This need for you:

interface Dialer0
 ppp authentication pap callin
 ppp pap sent-username xxxx password xxxxx

ikalmar

Thanks again for getting back to me. I have a silly question, is the username and password given to me by the ISP or do I create one myself?

Cheers dude..

Carlton

It given by ISP

Hi ikalmar

OK, I no longer get authentication errors. I'm very close to accessing the internet with the new 877W. Can you or anyone able to help take a look at my configs and let me know if I'm missing anything?

Really appreciate your help

HI,

This line not need:

ip nat pool pool1 192.168.0.1 192.168.0.20 netmask 255.255.255.0

I advise the following:

int range fast 0 - 3
 spanning-tree portfast
 switchport access vlan 2

ikalmar

Thanks but I don't think I need :

int range fast 0 - 3
 spanning-tree portfast
 switchport access vlan 2

I don't want to access through the lan. I would like to access internet via wireless.

Any other suggestions?

Cheers
