VR2800 5GHz loses internet connectivity dropout but 2.4G stays up
Hi,
Devices connected to my VR2800 via 5GHz constantly (randomly) drop out.
They lose internet connectivity while still being connected to the router.
Devices connected via 2.4GHz do not drop out.
The device could be a phone, PC, TV, it doesn't matter they all lose their internet connectivity.
This occurs at times of low traffic, not just high traffic.
I am on the latest firmware version.
I've check if there are other wifi networks using the bandwidth and there are none.
I have tried setting the channel to 48 and width to 40MHz which has been suggested in another thread, but that didn't change anything.
How do I stop the 5G devices dropping out?
