Reset router, can't connect to net - need help

Question

Here's my situation, I spent an hour digging through previous posts trying to solve my issue with no luck.
Had Cavtel DSL running to a Linksys wrt54g ver.2 router which was working fine.  My brother needed access to the network but we forgot the password which was set about 2 years before. 
I hit the reset button on the back of the linksys router and promptly lost access to the internet from my computer.
I contacted linksys help over the phone and after dealing with someone in India he told me that they would charge me to walk me through it.  I disconnected and tried cavtel... They told me to plug the cavtel modem directly to the pc.  I still couldn't access the internet at this point.
She then had me modify my tcp/ip settings and gave me nifty numbers that allowed me to get back online.  I asked her about the router and she said, oh just plug the modem into it and it will self detect everything and emphasized that I should call linksys and they'll be GLAD to help me out...
Needless to say, I plugged the internet into the router and once again can't get online.  I then tried to backtrack and plug the pc back directly to the modem and can't connect to the internet once more.  Contacted cavtel and their response was the classic, well we got you working directly we can't help you with router issues.
I don't have the install cd anymore, and I haven't a clue what to do to fix this.  Top this off, there are no other wireless networks around my house so I can't access this forum from home or any online 'easy help' tools or programs.
Anyone have any suggestions???  And yes I know the basics of accessing the modem, the 192.168.1.1 etc etc admin password. 
Thanks for help in advance.

Configuration for DSL connection:-
Before doing the following steps, you have to connect the modem to the
router's Internet Port and the computer to the Ethernet Port Number 1.
1. Press and hold the reset button for 30 seconds.
2. Then, unplug the power keep holding down the reset button for
another 30 Seconds.
3. Plug back the power back in, and keep holding down the reset button
for 30 Seconds.
4. Release the reset button.
===================================================================
Access the setup page of the router by launching an
Browser and type on the address bar, 192.168.1.1 and press enter. When
it prompts for the username and password, leave the username field
empty and provide password as "admin" (Without quotes)
click on ok.
On the main setup page the ""Internet Connection Type"" should be
on ""Obtain IP Automatically - DHCP ?. Click on the Save Settings
button.
Now click on the sub tab ""MAC address clone"".
- Click on enable
Click Clone & click save settings
Check WAN Ip on Status page of router ....
If getting Valid Ip .... try going online
If not ... power cycle for 4-5 minutes & then agian check the WAN Ip address .....
