Instead of resetting, an upgrade might be a better idea as michaelkenward says. 

That was an old single band wireless G device. 

Its speeds are atrocious and probably only suited to really slow dsl connections. 

It also slowed down big time if any wireless B devices were connected. 

It'd go from a blistering 20mbps wireless throughput to 8mbps. 

Even something fairly basic from the current generation is going to be significantly faster and have better security.
