Well OK the de-cluttering continues. I disconnected everything, reset the modem, and re-enabled the wifi function, and the readings are now consistently on par with the speeds the Belkin was delivering: 50+MB down, and 4.8 - 5.2MB up.

Anyone wanna buy a slightly over a year old Belkin N750 DB router? PM me I geev youse gooood price! wink
