First off, I mainly use Wifi at home and lots of devices have old wifi adapters in them. I run a fairly complex home network of bridged routers the force the 2.4Mhz to be N only connections and the 5Mhz to be AC only connections. My main pleasure laptop is stuck on 802.11 N Broadcom m.2 card due to the Lenovo bios only accepting approved devices. The Broadcom drivers, lack of documentation, windows, OpenWrt/dd-wrt settings/firmware have always made getting N like speeds very difficult. Recently this machine started to have difficultly streaming from you tube. Playing with the existing driver settings I could not fix the issue, thus dumpster diving for a better driver. I stumbled onto a 2020 driver for a 2012 card on the windows catalog. Playing with the driver setting, I was able to get the best rate and stable connection I have ever seen on this device.
Broadcom N card
Wifi iperf3 to Lan Iperf3 server: 17.3 Gbits/sec --> 17,300 Mbs
Xfinity SpeedTest: 93.3 Mbps
Other Internet Speed Tests: 20 Mbps
AC card
Never was able to get good data from iperf3 on AC devices.
Xfinity Speed Test: 120Mbps
Other Internet Speed Tests: 120Mps
120 Mbps Limited by legacy router on a 200 Mbps plan.
What I do not understand what is going on between the Xfinity Speed Test and the Other Internet Speed tests the Wifi N. All of speed test numbers are consistent with in 1 Mbps. Where is the missing 73 Mps? I do not believe its my router, since the Xfinity Speed test is out my network and AC should be showing something similar, but i do probably have an extra 80Mps available that could be masking some routing overhead. I do understand that the last mile should higher than the internet do to extra hops, traffic, etc. I just do understand the drop rate and why only the N wifi device.
