[SOLVED] Local Network Speedtest... Major Issue...

[rmsoft1]

Hello, I have run across a very strange problem. I think my only solution is to purchase a new router, but I would still like to know if anyone else has encountered this bizarre problem.

 

I have very slow transfer rates over local network when it involves getting anything from my desktop to my laptop. The strange part is, everything is fast and fine over the internet... Just not the local network...

Desktop LAN interface: Killer E2200 Gigabit Ethernet Controller

Desktop WLAN interface: Qualcomm Atheros AR9485 (802.11 B/G/N)(N150)
 

Laptop LAN interface: Realtek PCIe GBE Family Controller (Gigabit)

Laptop WLAN interface: Qualcomm Atheros QCA9377 (802.11 AC/B/G/N)

Wireless Router/AP: Netgear RangeMax WPN824N (N150)

 

 

I did a series of tests using iperf3. switching out each type of connection on both machines. Every combination.

You can see the image results here: 

 

I am going to be getting a new router that supports the 5Ghz band anyway, but I am still curious as to why I am suffering from straight up unusable local upload speeds from my desktop's wired NIC while still having perfect internet speed.

Turn off any QoS you may have on your desktop NIC, your router and your Notebook wireless adapter. 

try again and post results. 

 

that kind of behavior is mostly due to any form of QoS or energy saving features throttling back network performance. (I still believe it's QoS).

Thank you for the suggestion~ However, I have already disabled QoS and other energy saving features of the router, desktop NIC, and desktop WLAN cards. I Still have the problem. Looking back through the results, if it was the desktop's NIC, wouldn't the 3mbps speed persist though the other tests where I used it?

UPDATE

SOLVED: As strange it may sound I read around and one user suggested disabling windows defender's anti-malware. I was very weary on doing this, for obvious reasons. But I got to thinking, hey... if it did not work, i could just turn it back on. Well after changing the setting, and rebooting the laptop, I performed another iperf3 test. It's not the full 433+mbps, but I have walls between me and my router. It works!
