So I've had my PS4 for 8 months with no problems. However, one day last week the download and upload speeds when connected to Wi-Fi both suddenly dropped to 0.1-0.8mbps, from the usual 20+ download and 10+ upload. I hoped it would get better, and then searched online for solutions but nothing I have tried has had any effect.
All other devices on the network work normally, and it is fine when I tested it with an ethernet connection (although currently it's impossible for me to use one normally).
Has anyone experienced a similar problem, or have any ideas that might help? Or is it likely to be a hardware issue?
Thanks
