Hi Christian -

First - the wizards aren't the problem here - you network setup is :^)
Short story is that your workstations & SBS LAN nic need to be on the same
subnet without anything (read: router/firewall) between them.

The big problem is that you have the wireless router on your LAN. With a
dual nic configuration in your SBS (which is recommended), your SBS is going
to be acting as the router on the LAN. Here's what needs to happen:

1) Disable DHCP on the wireless router if it is active.
2) Forget about the WAN interface on the wireless router - make sure that
your LAN nic in your SBS is connected to the LAN side of the wireless
router.
3) Make sure that DHCP is enabled and running on the SBS.
4) Run the Configure Email & Internet Connection Wizard from the Server
Management Console. At the very minimum, it will correct your nic settings,
which should be:

WAN:
IP: 192.168.111.2
Subnet: 255.255.255.0
Gateway: 192.168.111.1
DNS 1: 192.168.16.2
DNS 2: <leave blank>

LAN:
IP: 192.168.16.2
Subnet: 255.255.255.0
Gateway: <leave blank>
DNS 1: 192.168.16.2
DNS 2: <leave blank>

By running the CEICW, you will enter your ISP's DNS servers. This allows
the CEICW to add these servers within the forwarders configuration of your
local DNS. When complete, all workstations should be grabbing IPs via DHCP
with a proper configuration of:

IP: 192.168.16.x
Subnet: 255.255.255.0
Gateway: 192.168.16.2
DNS: 192.168.16.2

HTH!
