Possible To Piggyback Routers?

I have a combo cable modem/router that is 802.11b. I would like to
run an 802.11g network with it. I don't want to lose any speed, so
need a separate router. Can I just piggyback (e.g plug the output of
the b router into the input of the g router? Would the b network
"see" the g network doing it that way? I suppose I could have the b
computers use the g router, and just ignore the b router.

Why not just buy an access point instead?

Some routers you can piggyback, but others complain that the WAN IP is
actually an internal address.

Which brand of router do you have?

It is possible, but why would you want to? Assuming you have sufficient
ports for all your computers, you'd gain nothing.

Because my new laptop with an 802.11g adapter built-in refuses to talk
to my 802.11b router, even though it can see other routers in the
neighborhood. Also, I don't want to be reduced to 11 mbps when I
could be using 125 mbps with the laptop. Don't want to replace the b
router because it is a combo cable modem/router, and was fairly
expensive.

Toshiba PCX5000 combo cable modem/router.

Buy a new access point.

Also, you won't get be getting 125mbps, more like 30mbps.

Could you explain why?

108mbps is a marketing ploy. While it works (sort of) it only delivers
20% - 30% extra speeds over real world WiFi speeds.

Standard 802.11g runs at about 20mbps. Accelerated technologies will
boost the speeds to about 25 - 30mbps.

The reason WiFi is slow is due to several factors such as:
Inefficiencies of sending data over the air
WiFi being a shared medium
Interference
WEP encryption
TCP overhead

So when all the overhead is accounted for, you're getting less than 50%
of the speeds. 30 - 40% of the stated speeds is not bad.

Check out this graph:

Notice how the "red" portion does not fill the entire bar chart? Sneaky
marketing eh... The red portion represents "real world" speeds (the
108mbp speed is overstated though).

If it makes you feel any better, even a 100mbit WIRED lan won't reach
full speeds, more like 60 - 90% depending on the client load and
topology.

I have a Linksys WRT54G configured that way. Instead of plugging it
into the cable modem I plugged it into one of the ports of my wired
router and it works fine.

Well, I had to do a couple things to make this work, which I found somewhere
on the web (maybe dslreports.com ?)

On the downstream router (G for you):

Set explicitly to a new IP outside the 1st routers DHCP range but same
xxx.xxx.x digits
Turn off DHCP
Set to 'access point' mode, not router to avoid double NAT (this goofed me
up for 2 days)
Plug cable from a LAN port on upstream to the uplink port on the downstream
Set wireless to different SSIDs and distant channels (e.g., 11 and 5)

My actual G speeds went up from about 12 mbps peak to 14 mbps with this
setup, but mostly it was fun and used the otherwise useless B WAP/router
for something. Don't forget to set the G to 'G only' after you get it going
tpo maximize speed.
