I'm not getting upload speed on a speed test website on my desktop, and I need that website for work. When I run speed tests on my smartphone, I get normal speeds, but not on my desktop. I've connected via Ethernet and even tried using a Wi-Fi adapter, but I still got the same results. Then, I tried connecting my smartphone via USB tethering and ran a speed test, but I still got the same results. I've also reset the network settings on Windows, but I don't know what else to do. When I run speed tests on other websites, I get normal speeds, but not on the website I need. This problem has been happening for 5 days, since Airtel restarted my router.
