My laptop Lenovo ideapad z570 with i7 2670qm 2.2ghz cpu/ ethernet realtekpci FE
and wirelss card Centrino N-1000.
The internet speed that laptop shows is 60mbps download. If connected to ethernet it shows nearly 90mbps. (cable speed is 330 mbps) My router is google mesh wifi.
Which is the best way to upgrade the laptop's internet connectivity? Can I replace the ethernet card to handle more than 100mbps? Or will a wireless card upgrade help? If so what?
