If you're outside of the 90 days of free support, yes it does cost money. Unless you have a total hardware failure. 

Or you can use the community forum as its free on here as its people from the public helping out. 

But we'd need a description of your issue, what you've tried, and your home setup. 

(btw, that router is a pretty low performing 10/100mbps router)

This place is free.

But if you called someone you found with a web search, there is a high probability that it is a scam.
