Last week my old router stopped working so I bought a new one. It seemed to work just fine because I could access everything and explore the internet as always (watch youtube, social networks etc). However, I decided to do a Speedtest (Ookla) when a website was having trouble accepting my inputs, whereas my smartphone had no trouble to. It was then that I saw there was a problem. The ping and download test ran normally, but the upload test would not run, the speeds would be 0,00 and then an error message would appear saying "A socket error occurred during the Upload test. A firewall could be blocking the connection or the server might be having some issues. Please try again later." . I have a laptop and my smartphone connected to the same wifi and both have no problems with that. I've tested the computer wired to the router and it works fine. My past router had no problems either. I've searched a lot and couldn't find any solution that fits my problem. I've made no changes to my pc, haven't downloaded any different softwares. The only change was the router.
