I've edited the title of this thread and added new info below....please help me if you can!





I'm working on a project right now and the production company has set up service with an ISP who has installed a Cayman DSL modem in our building. This box has four ethernet ports built into it. I actually don't know if the ports belong to a switch or a router.



Three of the four ports service different rooms, all three of which have hubs to accomodate the crew in those rooms. I've been given the fourth port and a Linksys router with the 802.11 antennae on it., but I can't figure out how to get it to work!



I have the BEFS41 at home, so I know how to interface with the Linksys. The thing that I can't figure out is the proper configuration setup. The Linksys is downstream of the modem/switch and it's setup to be dynamically assigned its IP....I just don't know if the Cayman is able to dynamically assign that data.



Can anybody let me know if what I'm trying to do is possible??



Thanks,

drew

    Okay, here's my update:



    The DSL modem is a "Cayman" which has apparently been purchased by Netopia. The thing is a DSL modem and a router. I'm plugging the Linksys wi-fi router into the 4th ethernet port of the Cayman and telling it to get be assigned its IP number dynamically.



    So, from the wall comes the phone cord.

    Into the Cayman DSL modem/router.

    4th port of Cayman to the WAN port of the Linksys.

    My 'book (via ethernet) plugs into port one of the Linksys.



    Regardless of the configs that I set up I CANNOT get out onto the internet. I just don't know how to get the Linksys to get its assignment from the Cayman. At one point I jacked my book straight into the Cayman to find out the IP that it was being assigned by the Cayman, then attempted using THAT address as a "static" IP from the Cayman to the Linksys. No dice.



    If you have any suggestions please let me know!

    I have the same linksys stuff here.



    you DO access the router's setup through 192.168.1.1 ?



    if you do, what kind of WAN connection type did you choose?



    It's a DSL connection, so I'd be tempted to choose PPPoE.



    But as the modem has a router included, it probably handels PPPoE itself, and is, at the router side, a DHCP server.



    Now, if that is so, you should, I reckon, choose for the option 'obtain an IP automatically'.



    One thing: if there is such a thing as an 'Uplink' port on the Cayman, you should plug in your Linksys into that one (it is normally next to port 4, at least it is on linksys).



    How are the other comps connected to Cayman? via DHCP?



    I don't really know if I can help. Maybe you should also have a look at the techdoc that comes with the linksys box.

    I'll look for an uplink port on the Cayman....the other folks are connected via DHCP. I run over and grab one of the ethernet cables off of the hub and plug in to check my mail and hit Appleinsider



    I'm telling the Linksys to obtain its IP dynamically, and the way that I know that it's still not working is that I'll be plugged into the Linksys with an ethernet cable, as I'm familiar with using a Linksys BEFS-41 at home. So I'm not even gettin out to the 'net with the Linksys....hmmmm.



    Any additional suggestions would be ga-rooovy.

    So tonight I called the ISP and asked them to take away the Cayman 4-port router/DSL modem and replace it with a regular DSL modem. I'll then hook that modem to the Linksys and be UP and RUNNING...when that happens. It's the most expediate solution.



    I know that there's a solution, but when I called their Tech Support the tech dude tapped out in under a minute reverting to the "we don't support...blah, blah, blah". I just wanted to ask some pointed technical questions about the Cayman....but this guy is behind a screen just reading back prepared questions.



    Pretty frustrating.

    This will sound stupid, but is the linksys set to the proper seting for crossover vs. straight-through?

    Ok I use a linksys with my dsl modem for my home network with no problems. What I would do first is goto 192.168.1.1 and click the status tab and see what the ip address is for the WAN. Maybe even do a dhcp release then a dhcp renew. next click the dhcp clients table button and see if there is anything listed, if your the only one n it you should be the only one listed. If nothing is listed well it could be something as simple as a bad ethernet cable. Next check system preferances-&gt;network, make sure where it says Show: that its displaying 'built-in ethernet' and compare the ip address shown with the one the router says its giving you.
