M500 download same speed as M200

Hello, I have recently changed to M500, the upload speed is fine but the download speed is at best the same as M200 and often slower than it was.  Resets and reboots have been done, lan or WiFi makes no difference, connections undone and re-tightened, all the same on MacBook, iPad, windows and android.  

I have included the logs, if anyone could give me some idea of what the problem is I would be very grateful.

Thank you in advance.

Re: M500 download same speed as M200

HUB stats look 'OK'. There were several errors this morning but it may have been a 'blip'.

Could you create a BQM and post the live (Shared) link?

Hopefully that link worked.


The link itself does work. Since the BQM starts when you create it, it will take some time to populate (A few hours).

Re: M500 download same speed as M200

I take it the amount of Pre and Post RS errors are not significant, the router had been powered on for about 2 hours.

Hmmm 2 hours with that many errors isn't great to be honest. The HUB having to correct errors can cause slower speeds.

We'll have to see what the BQM shows.
