Hi, 

I was hoping someone could help

I live in a flat, and work from home. The job I do is customer service and if I have no Internet connection I don't get paid by employer. I also have a physical condition, which means I find it difficult to do things which require manual changing connections far out my reach

I have HC220-G5 as main router connected to ONT in the cupboard. Then a basic tp link switch connected to Ethernet extenders going across the flat. I have my main setup in the living area. I have another switch there for PC, Playstation. I purchased the Archer MR200, as the TL-MR6400 doesn't have 3G/4G failover. However, when the router is off, it is not recognising and failing over. I tried to even plug the PCs Ethernet cable into the Archer MR200, but then that wouldn't give the main broadband connection as primary. Also my employers use VPN

I am a noob when it comes to this, if there's anyone who can give some guidance would be much appreciated
