I seem to be getting the reverse of everyone else - slow download and upload over wired LAN but much better over WiFi. It's on a network that's been used for ages, works perfectly with main fibre broadband.
Mobile carrier is UK O2.
Wired speed test on Fast.com = 520kbps down, 5mbps up.
WiFi test on phone to Fast.com = 4mbps down, 8mbps up.
