Though we all had high hopes for 1.20 it appears to be worse than all its predecessors. Previously VPN was my primary problem but now 1.20 has added to that constant WAN disconnects (TR609 among others every ~15 minutes) and also WiFi disconnects.
As I have mentioned in other posts, I work remotely, from home, over the internet. This means VPN is critical but even more critical is a persistent internet connection. It baffles me that there has been so much difficulty in delivering this service since I became a customer in January.
