Precision 5750 slow wi-fi (not Smartbyte, WMM or Driver)
I have a 9 month old Precision 5750 that has slow download speeds. Download speed is about 26Mbps. 5 year old surface book is 160 Mbps and iPhone is 210Mbps. I have searched for Smart Byte and don't see it installed on laptop. I have tried to turn off WMM on the router, but that didn't help. I have updated Wi-Fi driver twice but no change. Other than re-install windows, any suggestions on how to fix this. Painful to do demos on products with this speed.
Device: Precision 5750, i7, 16Gb (15.8 usable), Win 11 Pro, Wi-Fi 6 AX201 (update 22.150.1.1)
Internet: T-Mobile Gateway

I'm getting up to 300-400Mbps on 5GHz at 160MHz width and I was looking for this answer as well since I have Wi-Fi 6E on a access point. It appears that this card doesn't support 6GHz which is fine but my other devices can get close to Gigabit speeds on the same access point (Ubiquiti U6 Enterprise) on the same 5GHz SSID. I updated the drives directly from Intel on the Wi-Fi and BlueTooth to 22.160.0.4 released 8/14/2022 but didn't notice any major differences in my testing.
