Hey Hammy,
Sorry to hear you're not getting along with the R2!
What version are you running? I'd suggest making sure 5Ghz WiFi is set to 20MHz in Network Settings -> WiFi. It's also worth setting a static route to the R2 in your ISPs modem settings.
Please ensure IPv6 is switched off in both Network Settings -> LAN and WAN, there is a toggle in both.
When you say VPN errors, is the Rapp not loading for you now? Can you explain this one a little further?
With regards to the logs, we mostly use these as a way for developers to troubleshoot by seeing if errors are logged. Some log entries can appear sinister, but are realistically nothing to worry about, so I wouldn't read into this too much!
