My Archer MR600 will show that it is using 4G+ connection but only have a download speed of ~25Mbit/sec. Sometimes it will go up to speeds of around 130Mbit/sec but only for a short while. I have tried to use both Automatic and Manual band selection but it doesn't change the behavior. On the same network my phone gets 130Mbit/sec without any problems.

Also the device has started disconnecting once or twice a day so I have to manually turn it of and on again to get connection to the internet.

Can you please help me solve these issues, right now I am very disappointed in your product.
