You've done everything you can to resolve your issue with the router. Based on the fact that your computer gets an internet connection when plugged directly into the modem, it's likely that your router has died.
A service outage should not affect the router-you should have been able to connect to the internet with the router.
I've had a few outages with Comcast, and have not had any issues with my router after the service came back up.
If you need a new router, you don't have to spend a lot of money for one. The best thing to do is research (it's easy to do) first.
Go to the websites of stores in your area (Office Max, Office Depot, Best Buy, etc) and see what routers they have and how much they cost. You can get a decent router for less than $50.00. Need a wireless router? Search only for wireless routers. Check their sale ads from the Sunday paper. You don't have to buy a newspaper for the ads. Just look for the Weekly Ad link on the webpage. They always have routers on sale.
My Linksys router died a few months ago, and I purchased a D-Link wireless at Office Depot for less than $50, There's a wide range of prices, and hopefully you can afford something on the lower end.
As always, someone else may have suggestions for you to try before you decide a new router is needed.
