RMerlin is excellent firmware, but does not usually fix underlying issues, maybe worth trying a firmware that is say 6 months or older, as a few have commented recently that the more recent firmware's are buggy as hell.

other considerations is try to ensure router is not located near wireless phones, doorbells and the like as you could be having interference from another electrical device.

Also, are other devices like mobile phones having wifi issues on the 5GHz channel, or is it only you laptop/pc etc?
