Hello,
I'm trying to figure out why the Intel 7265 that came with my motherboard (ASRock x370 ITX) is limited to 433 Mbps link speed as opposed to 867. I did a search for others that had similar problems and tried to apply the settings recommended in those threads (in driver configuration and power plan) but without success. On the newest Intel wireless drivers (package 19.70.0 - motherboard's site just offers an older one) and Windows 10 has all the latest updates.
I am about 8 feet from an Netgear R7000 and my iPhone getting 867 Mbps from the same desk. Couple of weird things I noticed: upon disabling then re-enabling the device in Network Adapters, I get the 867 link speed for a few seconds before it reverts back (maybe because it's just initializing). Also, when detaching one of the antennas (left one), the link speed will stay the same but removing the other one will reduce it (even with the left one still connected). Are there other methods through software I can use to debug this, or might this be a hardware issue with the wiring of the antenna?
