Same problem here, guys. Using RailWire and almost all the time I get this "WS-37397-9" error code on PS4, when signing in to my PSN account, accessing PS Store etc., I also get Nat Type 3 whilst testing the connection. When I try to sign in to my PSN account from PC I get "Access Denied" message on this website:

The captcha solving thingy also pops up in some websites every once in a while. It is really annoying. Someone on the
PlayStation forum suggested that getting static IP provided by the ISP will solve the online problems on PlayStation 4. I called RailWire customer support this morning asking for static IP and they said, it is only given to SME access users not for Home access (which is what I use, Unlimited Plan 4 Mbps) users. Can't find any solution to this. Need help!
