Slow download speeds fast upload

Hello,

As I said in the subject I'm currently getting slow download speeds and fast upload.

My setup currently is a Super Hub 3 in modem mode, attached to an Asus RT-AC88U. I have the M200 package and was getting a solid 200Mbps pretty much all the time, sometimes slightly more! However this month I've only been getting 20-60, it varies a lot and seems to drop speeds from 110(ish) when you start the speed test, upload is as its always been (around 20) aswell as ping around 14ms.

After lots of messing around I've tried resetting the Super Hub 3 to factory defaults, connecting to its WIFI and trying the speed test which came back with the same behaviour. Nothing has changed in the last month or so, can anyone help? 

Thanks in advance!

Re: Slow download speeds fast upload

Here is a speedtest showing a download of 49 average with a spike at 167, this is not uncommon, upload speed quite steady.

During the day today the speeds were around 180 but still varying heavily.

 Here is a live BQM link

New link to BQM, router wasnt responding to the pings correctly

so, there doesn't appear to be any obvious issues with your router stats.. they all look to be within spec.. 

the start of your BQM isn't looking that promising though, but let's see how it plays out over the next 12 - 24 hours..

Re: Slow download speeds fast upload

Hi tehwolf thanks for your reply! 

I can agree there isn't much strange behaviour looking at the BQM although this doesn't reflect the status of our internet speeds.

I have run some speed tests today and it seems the internet speeds are dropping significantly throughout the day, below is a screenshot of the router speedtests I have run (QoS internet speedtest through the router admin GUI). As you can see there is a reasonably consistent 20+mbps upload but download varying from 220 (at 10:30) to 15 (just now).
