I've used the WIC-4ESW in the past.
You can assign each of the ports to a different VLAN to create up to 4
more routed ethernet interfaces. However, despite each switchport being
100Mb, the interface between the WIC-4ESW and the router is only 10Mb.
Traffic between switchports on the same VLAN will be 100Mb but traffic
between VLANS will be seriously limited as it has to pass through the
10Mb pipe to the router twice.
In Bruce's scenario, traffic would not pass between switchports but
aggregate Internet bandwidth would be limited to around 6Mb (10Mb in
theory only).

Do not confuse WIC-4ESW to be a 4 port Ethernet card either. It is a 4 port
Ethernet switch. It does however support 802.1q vlan trunking, so it may be
possible to separate the ports that way using subinterfaces and vlans. Keep in
mind however that PPPoE is not supported on subinterfaces, but I believe DHCP
is. (translation for cisco laymen...you won't be able to use the WIC-4ESW
ports for PPPoE connections like DSL, but you may be able to use it for DHCP
connections like Cable and/or satellite)
I know someone who inadvertently bought a WIC-4ESW thinking it would work for
them. I'll see if they still have it and if they do I'll try and do some
testing with it (as time permits).

Sounds like a really solid/resonably priced option.
Cisco 1721 has a one 10/100 Fast Ethernet Port.
I am looking to use this as a load balancer for three ISPs if it's possible
with this router. Providers are:
Bell (ADSL) - RJ-11 interface = WIC-1ADSL
Rogers - RJ-45 interface = ?
Sattalite - RJ-45 interface = ?
POE Switch - RJ-45 interface = ?
So, in total 3 RJ-45 and 1 ADSL port is needed. I can live with 3 RJ-45 and no
ADSL ports as well. Supporting 100mbps on all RJ-45 ports would definitely be a
bonus.
I know that the router has two WIC slots. WIC-1ADSL exists as Bill suggested.
Is there another WIC which can support two 10/100Base RJ-45 base in the other
WIC slot? Or maybe even a one port 10/100Base?
The reason why I am posing this question is because I only found a one port
10Base WIC module on the list of compatible modules for this router and no
100Base WICs.
Thanks,
Bruce

I currently have a WRT54GL in my home running the MLPPP version of Tomato, and
it is pretty solid but does lock up from time to time. The lockups aren't to
troublesome in my home situation, but would be annoying in a business
environment.
We found the same thing in the field for most of the readily available routers,
whether they be Linksys, D-Link, Buffalo or otherwise. Most of the time they
were pretty good, but in certain circumstances they just locked up, or wouldn't
reconnect PPPoE after an outage, or other weird stuff.
For that reason, we are now solely deploying Cisco 1721 routers for all of our
business customer deployments (whether they use VoIP or not). You can pick them up
on eBay from a variety of sources for< $100. I think we bought 100 of them for
$50 each. Then we put the WIC-1ADSL card into the router (they are also around $50
on eBay). In some cases we put in 2 DSL cards and bond the links with MLPPP.
The great part of this solution is that for around $100 (for the single DSL, or
$150 for dual) we get a router that runs Cisco IOS and all the great things
that come along with that. The reliability is outright awesome...they just
never need to be rebooted.
The downside is no web interface, so you have to know Cisco IOS or be fairly
comfortable with a command-line interface. Also, there is no wireless in this
series of routers, so you will need some sort of stand-alone AP if the customer
wants wireless (most of them do).
Regards,
Bill

Another vote for Tomato, the traffic shaping works great whereas it
just seemed to cause problems with DD-WRT. Used to have DD-WRT loaded
on up to ten WRT54GS but found it slower than Tomato and the interface
more cumbersome.
Another vote for the ASUS routers mentioned. Heard that the Buffalo
routers are OK too but I've never used one before. If you want to
spend a bit more, consider Soekris or Routerboard.
