The Sonic router we supply will deliver full symmetric gigabit speed.
For those that are capped at 100mbps up, uninstall an ethernet driver called 'cfosspeed for faster internet connections'; it comes from motherboard software from manufacturers such as: ASUS, GIGABYTE, ASRock and MSI
Was wondering why my wifi had 300 down/up when ethernet had 900/100. Uninstalling this fixed it for me
