Two 3Com wireless routers to extend range

I have two 3Com 3CRWDR101A-75 officeconnect wireless routers. One is
connected to a DSL line and the small wired office network.

The second is to be used as a range extender. I set it up with WDS
enabled, selecting the first network that is easily found.

What else do I do for wireless-enabled laptops to connect to the whole
network. i tried connecting to the second, but could not see the rest
of the network.

Is there anyhting special that needs to be done? Do I have to set up
the first with WDS enabled, and looking at the second?

It seems so obvious, nut the manual does not say anything.

* I don't know that wireless router specifically, I could look at the manual
if I had a PDF...

In my experience with WDS, you have to enable it in every router that
participates in the WDS
network. Each router is configured with the MAC Address of the other ones
that it will connect to.

If there are only two, then each one needs WDS on and the MAC Address of the
"other" router.
You also often must use WEP security, and the same channel number on all
routers. You can
use different SSID network names to make it easy to know which one you
connect to.

Usually you configure this with them side by side, CAT5 wired network
plugged into both of them
renumber their IP Addresses manually to be on the same subnet (makes them
easier to work on
later on.) probably planning your network around some Subnet Scheme often
matching the
device that does DHCP on your network. (You might have to make sure that
manually configured
IP Address devices are still within the subnet range, but outside of the
DHCP assignment range.)

Turn off any firewalling in the routers... make sure they can't block
anything especially ping.

Once they are configured and reset. Seperate them and test to see if you can
connect to the
non-wired one, see if you get correct DHCP assignment including IP and
Gateway and DNS.
Test pinging the main wired wireless router from the farther away
wireless-only one.

Then try Internet.

See how that works for you?

The manual is located at,
http://www.3com.com/products/en_US/s...=3CRWDR101A-75

Pretty much the same advice as above. Although I would leave the SSIDs
the same. And verify connectivity of WDS by connecting to the web
interface by cable and verify connected stations. And try upgrading
firmware to assure that any bugs are corrected and WDS synchs with
your other unit.
