I am faced with very poor speed on my local network between my wired desktop and wireless laptop...
Network setup details (At the time of testing):
Router: NETGEAR Nighthawk AC1900 Dual Band Wi-Fi Gigabit Router (R7000)
Laptop WLAN: Qualcomm Atheros QCA9377 Wireless Network Adapter (5Ghz RSSI: -46)
Desktop LAN: Killer e2200 Gigabit ethernet controller
Laptop LAN: Realtek PCIe GBE Family Controller
Desktop WLAN: Qualcomm Atheros AR9485 (2.4Ghz RSSI: -43)
I used iperf3 on both machines. I performed EIGHT different tests using each combination of devices in each way
Special notes: I am connected to the 5Ghz band via laptop. the ap name is RMSoftware DevNet-5Ghz. WP2PSK is enabled, and WMM is also enabled.
The test below shows even worse performance. Receive window for iperf3 is default 256kb. test time is 10 seconds.
The only combination that failed was the Desktop LAN to Laptop WLAN. The maximum upload from desktop speed reached <1mbps out of the possible 433mbps+ (according to windows network details)
I have tried transferring files from my desktop to my phone over network. I hit my peak wifi speed (Which is great and expected.) I have also tried laptop to phone, also hitting peak wifi speed as expected...
Things that work as expected
- RDP between desktop and laptop are hitting full bandwidth (GREAT)
- Steam in-home streaming between the two are also (beautifully) working (Awesome!)
Things that don't work between laptop and desktop
- Iperf3 testing
- Network file transfers (network shares, drives, etc.)
So my question: what is causing uplink throttling with transfers and benchmarks, and how do I fix this. I have a development partition I share so I can work on dev projects from both machines, at any given time.
Generic online suggestions I have tried
- Disabling LSO on desktop (Laptop didn't have this) -- FAILED
- disabling autotuning (netsh ... autotuning=false) -- FAILED
- Tested all the different duplex settings (desktop, as laptop didn't have this) -- FAILED
- GPEDIT: configure qos bandwidth limiting (Desktop only. laptop uses win10 home) -- FAILED
- Disable QOS via router, desktop, and laptop network settings -- FAILED.
Lastly, I apologize for this chaotic post, I am at wits end.
