Really depends on if you actually have good speeds from your ISP. If you do then the modem/wifi could be the point at which your speeds are slowing down. In that case upgrading these would help with the speed loss.
Will Dann, I have 3 points Google wifi with a AT&T router. Each Access Point is is placed at far ends of my 3000 ft home with 2 more wall in between..My Speed Test is 29 mpbs Download and 4.5 Upload. The app tells me “Your Internet speed is pretty quick”. I have I also have 4 TP-Link WiFi Wall Extender, 16 devices. The Speed Numbers are nowhere close to what you produce. Any suggestion?
I figured it out. The point needed to be factory reset. You do this by unplugging the power then hold down the button on back then while holding the button plug the point back in.
Be warned! This Google Mesh automatically switches channels between 2 mhz and 5 mhz. I noticed my wifi CCTV and Blink CCTV is not compatible as it will not work with 5 mhz. So when it switches automatically to 5 mhz channel your CCTV will stop working. I wish the reviewer pointed out this instead of praising how good it is without pointing out that Google Mesh is not good with devices that only uses one channel the 2 mhz. So please make sure you are aware of this. This reviewer is not totally truthful. I hope my feed back will help with your wifi router choice. Google Mesh cannot use devices that uses one channel the 2 mhz only.
