My download speeds seem to be all over the place with my new M200 install. I've seen wifi speed results as low as 0.5 Mbps down on Speedtest, followed by 80 Mbps after rebooting the router.
Right now it seems to have stabilized somewhere around ... 8 Mbps. Also, websites like Gumtree and Facebook are giving me CAPTCHA bot-checks very frequently, perhaps that is related.
Don't have a device in the house with an ethernet port, so unable to test LAN speed unfortunately. Router status page gives these details (rebooted the router maybe 15 minutes since).
