My Wi-Fi speed was fine when I first got my r3 but it suddenly went from 700 to max 150. The upload speed on wifi is great but only the download speed is slow. (ethernet speed is GOOD).
I tried to turn off qos, turn off ipv6, switched antennas around, tested different 5ghz width but nothing seems to be working. I am on the latest early access build (4.0.179)
Is there any way for a tech support member to get access to my router or tell me what to do? Thank you for your help. I attached screenshots of my ethernet speeds on pc and Wi-Fi speeds on my iPhone.
