Upgraded to 500Mb/s from 350Mb/s speeds are now slower

[Buzstringer]

I Upgraded to 500Mb/s from 350Mb/s initially for the first few days i was getting over 500Mb/s however over the past week the speed has dropped to below 200Mb/s.

Tested hardwired on in Modem mode, and router mode on Speedtest.net, Google Speedtest and Steam.

Tried power cycle, power off for 30 minutes, factory reset. 3 PCs (2 x Windows 10, 1 x Ubuntu).

Welcome to our Community Forum! Thank you for your post and I'm sorry to hear that you're experiencing some ongoing connection and speed issues! 

I understand that you have carried out your speed test on a wired connection, that's great to hear! You can also read more about how to complete a wired speed test here.

I was able to locate your account on our system via the details you have provided on your Forums. After running further checks, I cannot see any issues listed on the system. 

Can you please tell us a little more about the problems you're experiencing, and we'll be more than happy to look into this further.

Hello @Paulina_Z

Thank you for taking the time to look at my account.

I have been doing some more testing over the past few days, and it appears that there is an intermittent issue with my personal hardware.

The hub is fine, i think I just got unlucky when I was testing before.

My Asus router, has a strange behaviour whereby anything over 400Mb/s coming in through the wan port causes it to drop the the speed to around 200Mb/s but only after about 5-10mins.

It made it very difficult to diagnose between reboots ect.. 

So now I need to replace my router (or try to fix it) by it might a nice excuse to upgrade to WiFi 6 mesh network.

Anyway, sorry I wasted your time and thanks for your help.
