new router - dropped wifi & significant packet loss on 5GHz, but 2.4GHz ok
We have had this router for less than a month.
We initially had "smart connect" turned on, but over time, the router would become unstable (devices would connect, disconnect, connect, disconnect repeatedly all within seconds) until we restarted it.
After a few times of this happening, looking at the router stats, all the devices connected recently were in fact connected to 2.4GHz, none were on 5 GHz. So we turned smart connect off and configured the two bands separately to look into it further.
We connected two laptops, one to 2.4GHz and one to 5GHz and ran pings through them at the same time. Both laptops were right next to the router. The 2.4GHz band had virtually no packet loss, the 5GHz band had almost 10% packet loss.
Help? Could there be some problem we can fix? Or is it likely to be a problem with the hardware itself?
