[SOLVED] Problem with router - wired & wireless

[EatTheApes]

Hey, checking if anyone can help out with our router at home. It puts through horrible speeds, regardless of wired or Wi-fi, 2.4Ghz or 5Ghz.
It is a Asus RT-AC52U B1.

I tested speeds with cable directly from wall to pc, using speedtest.net I got around 800Mbps. (I didn't even know we got this kind of speed..)
Through router, wired and wireless, I get about 5Mbps.

Another thing I find strange, when downloading anything, download speed tops at around 600kBps. It also slows down all internet access, on the downloading pc and all other devices connected, sometimes to the point where websites don't load. This also happens both wireless and wired through router.

I have tested with different three different pc's and on my phone, same result on all.
I upgraded the firmware but that didn't help and I did a hard reset but that hasn't solved anything either.

We have no modem, internet cable goes directly from wall to router (or pc during my tests)

Start with a factory reset of the Asus. Then configure only the REQUIRED things like admin password, SSID and WIFI password. Then test with a wired connection.
