Should I do a factory reset?

Thank you for the quick reply.  Not sure where to look for qos, access control, traffic monitoring, parental controls.  I went to the administration page of my router and only found a traffic metering setting which was set to off.  Are the settings you mentioned found on the router or the laptop?  After establishing these things, I can then do the hard wire from the router to the laptop and report the results.  The modem (ONT) I am using was supplied by the ISP which they remotely tested and claimed is functioning properly at 1 gig speed.  Although the provider's tech support only addresses issues with their hardware, they did mention that there might be an issue with a firewall.  I poked around and found firewall settings but nothing that looked like it pertained to the router or internet settings so I left everything alone.  I apologize for needing a bit (or a lot) of hand holding...wifi/networking issues are not my strong point.
