The ONLY firmware I have found to have a stable connection is 4.1.27. I have updated with each new release and it afterwards the disconnects start again so I have to downgrade each time.

I updated to 4.1.30 at the weekend and suffered again from the Lan randomly dropping off again. It would only be connectable for a few hours at most. I have since gone back to 4.1.27 and have had no issues again.

If you're desperate for a VPN you can always get a mini router such as this https://www.amazon.co.uk/GL-iNet-GL-AR300M-Pre-installed-Performance-Programmable/dp/B01I92T754/ref=asc_df_B01I92T754/?tag=bingshoppinga-21&linkCode=df0&hvadid=&hvpos=&hvnetw=o&hvrand=&hvpone=&hvp...
