Yeah, thats an old timer to be sure. Did you check to see if there is a newer firmware upgrade for it that might solve the problem?
Look here:

Click 'downloads', follow the instructions to find your model of router, and then download the latest firmware. Then open up the users guide thats right next to the firmware listing on the netgear web site. In the advanced setup section, it shows you how to connect to the routers configuration page with your browser, select 'administration' and then 'firmware upgrade', then supply the name of the file you downloaded. Some models of this router have received firmware updates as recently as last year, although others havent been updated for >4 years.
As far as a new one, its pretty hard to find a modern non-wireless router but you can turn off the wireless section of any router, and its usually not too tough to do.
Here's a couple of router options:

Good reviews, $37, does have wireless N capabilities should you want wireless sometime in the future but it can be turned off.
Or if you want to try something really cheap, check this out:
http://www.buy.com/prod/netgear-rp6...h/q/loc/101/210817631.html?adid=18007#cRevSec
$9.99 with free shipping. Its an older model router but netgear has kept up with newer firmware. Its 'recertified', but since its such a simple product with few parts to replace, its most likely that a customer received it and the power brick was bad and they returned it, or they did something wrong in the configuration and locked up the box and couldnt figure out how to undo it.
Couple of other inexpensive but decent routers, also recertified.

That last one, the WNR2000, is a very good router at a very good price.
