Hi all,

My in-laws recently changed over to Orcon's 100/20 fibre.
They weren't really impressed with the WiFi speeds, so I had a look.

A couple of weeks ago, I ran speed tests using WiFi on the Netcomm NF4V (stock Orcon modem) using a phone and laptop in the same room as the modem, which returned very varied results.
Downloads were anywhere from 1-40mbps down and uploads ranged from 1-20mbps.
Just to check it wasn't the connection, I hooked up a ethernet cable to the modem and ran a few other tests, resulting in fairly consistent speeds around 100/20.

I have the same plan, with the same modem. A few years ago I added a Netgear R7000 via ethernet to my modem and greatly improved the WiFi.
Thinking my in-laws' WiFi issue was similar, I bought them a Netgear R8000 and connected it to the modem via ethernet.
With the new router I get fairly good download speeds (60-90mbps) down, but only 1-3mbps upload! Weird!

I enabled the WiFi on the Netcomm NF4V and performed a few more tests resulting speeds around 40 down/20 up (the upload on the Netcomm seemed more stable).
Reconnecting the R8000, I connected to the 2.4G, and both 5G WiFi bands and couldn't get upload speeds past 10mbps.
I thought it might be the room, so I took my 10m ethernet cable and tried moving the R8000 to the living room.

To eliminate variables, I brought the R8000 home, replacing my R8000 and consistently get over 90mbps down and around 20mbps up with wireless and wired.

I have run out of ideas, and I can't pinpoint the issue from my tests.
The Netcomm NF4V seems to have good upload now, but delivers less than half the download bandwidth, whereas the Netgear R8000 delivers good download speed but unusually low upload speed.

Anyone else experienced this before?
Any ideas would be much appreciated, thanks!
