Newbie 1812 IOS Boot not work properly

[explorer1979Jimmy]

Hi all,

I am using 1812 Router and with 32M CF Card and 4G CF Card too with 384MB RAM. I setting it work well on IOS advipservicesk 124-15.T12 by SDM and just basic Firewall etc ....

But when I not change any setting and using the IOS advipservicesk9-mz.124-24.T, plus other 124-20 or above IOS

After reload the router by any advipservicesk9-mz.124-20 or above IOS My Router will out of work.

It FE0/2 interface on the configuration is 10.10.10.1/29 with Vlan1

But I can ping my workstation 10.10.10.2 on the same LAN and also the the FE0/0 DHCP then connect to my ISP Router also not work anymore.

But if I change back to the advipservices 124-15.T12 IOS and reload, the Router will all thing come up again like my WAN, LAN all can using no problems....

Why the other IOS image make the problems like that?

Thank you very much and wish you have a nice day.

After run the "erase startup-config" command and reload... the 12.4(20) above image work

I can ping www.yahoo.com on the console.

But all old setting are lost I need setting the 1812. But this time the Cisco SDM not come to work again.

Do any one can teach me how to setting the 1812 can online to access both WAN (Internet) and LAN

Here are my environment.

ISP give me IP by DHCP.

And I using 1812's FA0/0 as WAN interface, and no change anything, it can handle the IP by DHCP auto ....

FA0/1 is not setting anything like it default

FA0/2 connect to my workstation (1812's Switch Port) but VLAN1 is not setting like default ...

I am using other computer to post here since now the 1812 come back to default ... and the problems is it can't open the SDM again. Only can access by console and CLI

Here are my running-config
