When I run a speedtest on my desktop PC from the Google search page, my download speed is consistently 250-265Mbps and my upload is either 0 or 0.01Mbps. If I run a speedtest from any other site my download is the same and my upload speed is 100-110Mbps, as it is supposed to be. If it were only an issue when running a speed test I wouldn't care, but this same issue with uploads happens when using any Google services including YouTube, Gmail, re-captcha, and Google Drive. As far as I can tell, this does not happen with any other websites, at least it isn't something that I experience with any of the other websites that I regularly use. I have gone through many FAQ's and user-made videos and forum posts trying various things to fix this issue and the first breakthrough happened recently for me.
Recently I discovered that this is only an issue when my PC is connected to my network via a wired connection though. When connected through WiFi, I can upload to these Google services, but my upload and download speeds are slower across the board hovering around 70Mbps both download and upload. I'm just hoping that there is a way to get the uploads to work through the wired connection as WiFi can be a little dodgy sometimes due to the plaster walls in my home.
Things I have tried with my wired connection. When I ping Google or YouTube I get no loss at an average of 21ms. I have tried plugging the ethernet cable into each of the ports on my router as to make sure it wasn't an issue with the specific port I was already plugged into. I have enabled/disabled the Large Send Offload V2 for both IPv4 and IPv6 on my ethernet connection. Ensured that my device drivers and BIOS are up to date. Hard reset my router and my modem. Tested three different cat6 ethernet cables, one long (35ft) and two shorter (6ft) cables to make sure it wasn't a broken cable.
