Ok so recently the download speed of my pc has been reduced from around 30 mbps to anywhere ranging from 1-8mbps. My upload speed is nearly always around 10 mbps which I've been told is completely fine. When connecting to the modem with my pc via ethernet i receive around 220 mbps download so I'm assuming that means the isp side of things is in order (maybe?). The Netgear N300 wireless router is what we were using previously, and upon isp tech inspection he recommended that a new router be purchased seeing that ours was fairly old. Today we purchased a Netgear Nighthawk AC1900, which i read multiple great reviews on, however our download speed is still the same. The netgear tech i talked to walked me through resetting the router/modem multiple times and also connecting to what I'm pretty sure is the public google dns server. None of which have helped. He recommended returning the router we just purchased as it may be faulty (I'm inclined to believe that since the same issue is happening with a separate router that it may not be the router at fault). I've attempted to change the qos priority of the desktop to maybe increase the speed by at least a bit, but that has not been successful. My knowledge of routers and ways to tweak them is extremely sub par and the technical support of netgear and my isp has not been very helpful thus far. Any recommendations on what route I should take to troubleshoot this issue would be greatly appreciated. Also, The difference between upload/download on wifi vs ethernet is non existent in this case, and the download speed reaches nearly 20 on mobile device speed test.
