I am getting a public ip from the modem and DHCP looks fine.
I think problem is with FastEthernet1 shows no IP and can not ping my PC. PC displace the IP of 192.168.100.2 and proper DNS and gateway info. I am missing something please help

Thank you in advance.

looks like you got a typo on int fa 1. Looks like you have vlan 10. Shouldn't it be vlan1?

however, I do see you have VLAN10 in the config, but your sh ip int bri shows:

Vlan1 192.168.100.1 YES NVRAM up up

I would take a look again at the config. other than that everything else looks good.

Thank you for your help.
I updated my config file. When I use vlan 1 I can not assign switchport to it on Fa1
but when I use vlan 10 its fine I see switchport info under Fa1. So I just used vlan 10
is that ok or do I have to use vlan 1?

The ports are assigned to vlan1 by default so it does not show up in the running config.

The static default route is pointing to fa0 interface. I would change the "interface fa0" to "dhcp".

I'd get rid of these ->
no ip domain lookup
ip http server

if you run the httpd, set up authentication.

I got it. It's working it was that default route I changed it to ip route 0.0.0.0 0.0.0.0 dhcp release renew ip on my pc
and bang its up now. Great thank you all. Especially sysctl. The only think is if dhcp is assign to fa0 why
default gateway does not work if I just assign fa0 why it has to be dhcp not sure. But it works.

Not sure how that fixed everything unless you changed the VLAN stuff too.
