Slow Internet on deco M9 plus, Main Network ONLY
On my new M9 plus, I get really great speeds uploading and downloading on the GUEST network. But on the MAIN version of the network, I get almost no internet. In fact sometimes I can't get any internet at all.
GUEST network: 50mbps down, 6mbps upload
MAIN network: 10mbps down, 0.06 Mbps upload
It was working fine until just today and nothing changed in my settings.
Rebooting didn't change anything, modifying the qos didn't change anything. I also tried disabling and re-enabling the main network.
How do I fix this?
Edit: to clarify, the speed test on the router app is fast, but when using a client and a web browser the Google speed test is only slow when connected to the main Network.
