Cisco router trouble. Please help!

[AWBbox]

I recently bought an unused Cisco 877W ADSL router to use at home. When it arrived it came with SDM 2.4 and an outdated version of IOS. I upgraded to SDM 2.5 and IOS 12.4(15)T and everything was still working ok, though I had not configured it correctly up to that point. I was really struggling getting the WAN port to obtain an IP from my ISP, I am with Virgin Media and we have a dynamic IP. After many failed attempts, the configuation seemed to be a real mess so I decided to get the router back to factory settings again, I read up on how to do this using CLI in hyperterminal and promptly carried it out. But I forgot to back-up my settings first, I now know that was a dumb thing to do. Since I cleared the running-config I have not been able to get back to SDM, I still have access to the CLI and there is a running-config on the go that I made using the basic configuration function at the command line. I can't seem to get the ports set up right as no computer is able to ping the router or launch SDM on it, I'm in a real pickle, I'm new to Cisco technology and I would really appriciate some help getting back to where I was when I took the router out of the box. Thank you.

If you've stuffed it you can try this:

wr er (erases the startup config)
reload
skip interactive setup
then paste this in (you may have to ammend some of it to work) but it should allow you to get an IP address when plugged into fast-ethernet 0 and allow you to access SDM..
Username admin password cisco...
Note: I don't accept any responsability if this breaks anything!

conf t
interface vlan 1
ip address 192.168.1.1 255.255.255.0
no shut
exit
!
ip dhcp pool lan
network 192.168.1.0 255.255.255.0
default-router 192.168.1.1
lease infinite
address range 192.168.1.200 192.168.1.254
exit
!
username admin password cisco priv 15
ip http server
ip http authentication local
ip http secure-server

Thanks man! I didn't copy and paste all that but the bit about the vlan and the 'ip http server' bits did the trick just dandy

For other people how might have the same problem and stumble on this thread, the 877 router has 4 Fast Ethernet ports, non of which are layer 3. In order to assign an ip you must make a vlan interface then assign switchport access from the port in question:

interface vlan 10
ip address 192.168.1.1 255.255.255.0
!
!
interface FastEthernet0
switchport access vlan 10
no shutdown


But for you Cisco buffs; I have another question. At the moment I am using the Advanced security IOS, in SDM I cannot use the IPS or QoS functionality of the router. Those are functions that were important to me when making the choice about a new router, I have a .bin of the very latest Advanced IP services IOS. I have three questions:

1- Will the Advanced IP Services IOS grant me access to the IPS and QoS functions of the router.

2- If I were to upload the .bin file, would it over-write the Advanced Security one I have now, along with any configuration settings I have in place?

3- How do I actually add this Advanced IP Services package to the router? I haven't actually ever done it before as the Advanced Security one was done automatically with the SDM update I did.


Thank you all for your support!

I answered my own questions this morning

1- Yes

2- You have to delete the old one and then upload the new. Configuration is not touched.

3- tftp server app

I'm learning loads from this whole process. I love it! Anyway, thanks again for your help
