My download speeds are terrible compared to Speedtest results and through put test results.
My PC is a 2018 dell XPS 13-9370. Ethernet is connected through thunderbolt port. Wireless card is killer wireless ac 1435. It was the only device connected while troubleshooting everything below.

I have 250 Mbps internet and I have verified I get 250 Mbps from my ISP. When I connect to the R8000p with CAT6 I average around 242 Mbps from speedtest.net. I also average about 240 Mbps using iperf through put tests. So everything seems okay 240 Mbps is 30 MBps which is great, but when I download an actual file the download speed is about 500 KBps which is 0.5 MBps. So it is 60 times slower than the speed test results. To verify I have tried different file download sizes and types from different locations and the speeds were the same. I tried ~140 MB general software like VirtualBox , 1 GB iPhone ipsw file, and 4 GB OS image file.
I have researched everything I can about similar issues the common recommendations were to turn off traffic meter and QoS and to do a factory reset. I tried it all and no change. Others said to update firmware, still nothing. Some said go back a few firmware versions still nothing. I tried 4 older firmware versions back to the very first. I am now at a loss. Everything IS working I just can’t get any speed out of it. I know I can’t get the full speed but 60 times slower is crazy. I would be completely happy with 20MBps (160 Mbps) but to see the download speed in KB is really frustrating. Any help or advice would be much appreciated. I have some technical experience but not really in this area so simple explanations would be great.
