I recently upgraded to 1 Gbps and since I am still getting 300 around most of the house I'm pretty sure I need new hardware. I had been using the google mesh system and after the upgrade, I still get 300 Mbps directly connected to it on my PC. My router and modem are both across the house and I can't move them. I also only get about 50 Mbps on my phone around the house and sometimes less at the corners. What kind of hardware do I need to get faster speeds on my PC across the house and to wifi devices?
