Hey

I also have 1GB internet using the TL-R605 and quite often notice the speedtests vary massively while on schedule (24 Hours)

If memory serves me right the R605 uses  ookla or fast.com (cant remember which) to test the speed, like a lot of services now they struggle to deliver full 1GB speeds and regularly comes in ~600mbps for me also.   Had it as low as 450 and as high at 800

Like all these online speed tests, from experience I've never found them reliable once you go over the 300mbps speeds!

Hi Philbert,

Thanks for your feedback, it is just weird that both are Speedtest powered iaw the pictures above and I get a huge difference at the same time.
