RAX43 must disable OFDMA to work with Killer AX1675i adapter
Nighthawk RAX43, Operation Mode: Access Point, Firmware Version: V1.0.12.120_2.0.83 New laptop running Win11 and using Killer WiFi 6E AX1675i 160MHz (211NGW) adapter. Every time AX1675i conne...
I don't think resetting the RAX43 to factory default will resolve the issue as it is working fine as long as Killer AX1675i adapter is not connected it.
- OFDMA is related to the way how wireless signals are segmented, channel, and bandwidth is managed.
- OFDMA allows better sharing and utilization of bandwidth within the network when there are many devices connected.
- In my case, without Killer AX1675i connected, OFDMA seems to provide approximately 10% to 15% gains.
In the future, when chance and time permits, I might give the resetting to default option a try - but I am not hopeful on the result.
Unfortunately, I don't have another unit with OFDMA capability to test with the Killer AX1675i adapter. However, I doubt that Intel nor Killer will manufacture adapter that is not in compliance with wireless standards around the world. Nonetheless, it is sad and unfortunate for me to experience this in my unit which further shattered my expectation from Netgear equipment.
OFDMA may or may not be always the best feature. Doesn't mean you have to have it enable or disabled.

Seems that maybe the mfr of your adapter could help improve as well. Maybe two sides to this.
I've seen Killer features cause problems that normal are not seen with other branded adapters. Killer add there own features (QoS) and items that may and can cause issues regarding operation and compatibility with brand name wifi routers. Not the first time.
