It's in Spanish but I did try every single step on the FAQ, also, there's a lots of images, showing pings to SBR, EUS (from Uruguay, almost same ping), ports forwarded, speed test, ms info, and network properties. it's very complete

Thanks for getting back to me. I can see you have another case in progress.Please provide any relevant information on this support case, so we can look into this.- Ubisoft Support
