Is this 2500 series Cisco router toast?

Hi,
I don't have a lot of experience with Cisco router, but I think this is a problem.
I hope this is posted in the correct location since I thought people in networking might have more experience with Cisco routers than the hardware bunch.
Anyway, before I recommend to the client that they replace the router, I would like some opinions.
I have a Cisco 2524 that may be the source of network problems.  I've been going mad trying to isolate the cause of a myriad of seemingly unrelated problems so I needed to reset the router password.
What happened was, when I attempted to reset the password, I lost the entire configuration-the router went back to all its defaults.  I chalked this up to my inexperience so I reconfigured the router.  Subsequently, I had to shut the router off again, and when it rebooted the configuration was again back to default.  I thought maybe I forgot to use the "copy running-config startup-config" command so I configured the router again for the second time.  Well last night, I was telneted into the router when it suddenly dropped the connection while I was trying to create an access list.  Sure enough when I called the client this morning their internet was down because the router lost its configuration.  Strange thing though is that when I had the client hyper-terminal to the router, the router's name that I put in was still there, but the rest of the configuration was gone as demonstrated by the show config command.  Am I missing something here or is this router screwed up?  Please give me your thoughts.

Laura,
Sounds like the config register is not set correctly to boot from the config file.

You can see if the startup config is still there:
Router#sho start
Compare with
Router#sho run

If the startup config is still there and complete, you can load it with:
Router#config mem  <== loads startup config

If both of these are positive tests (startup config shows your changes and loads correctly), then it is proof positive that the config register is simply set to ignore the startup config on boot.

From the router command prompt:
Router#show ver
Look at the very bottom for the config register setting. It should be 0x2102
If it is not, then
Router(config)#config-register 0x2102
Router(config)#end
Router#write mem  <== short for "copy running-config startup-config"
[OK]

ok I will check, but I did look to see if show startup-config and show running-config were the same and they were.  I also made absolutely certaing that I ran the "copy running-config startup-config" command.
Thank you

I believe this is what you are talking about.  I'll try it tonight when I am at the terminal.

Irmoore,
Thank you!  Do you know that off the top of your head or is there a good resource that you like?  Maybe a little of both?
thanks again Laura
