Nighthawk C7000 Slow Upload speeds on Laptop

I have Spectrum 100Mbps internet.  I was using Spectrum's Technicolor DPC3216 modem which was giving me 100+Mbps connected through ethernet cable.  I purchased the Netgear C7000 and installed.  On laptop, I can now only get about 35-45 Mbps with either ethernet or WiFi.  It makes no sense since I was getting 100+Mbps on the laptop with the Technicolor modem through ethernet cable.  But now I can't even get 50Mpbs with the Netgear C7000 modem with ethernet cable.  I have done a factory reset on the modem which improved nothing.  From the moment I installed the C7000, I have never seen more than 35-45Mbps.  I have no clue what do to!  Very frustrating!  Anyone with advice??

The ISP could have the modem coded for the wrong speed and the old modem still has the codes for the 100+ Speed I suggest contacting them.
