Severe Bufferbloat on Wireless Upload – Archer C64
Severe Bufferbloat on Wireless Upload – Archer C64

Hi everyone,
I’ve been running bufferbloat tests on my TP-Link Archer C64 and consistently getting poor results on the wireless connection—especially during upload active time. The LAN connection performs well, but Wi-Fi shows significant latency spikes.
Here’s what I’ve tried so far:
-
Changed channel width (20/40 MHz)
-
Enabled/disabled QoS
-
Enabled/disabled NAT Boost
-
Tested with only one device connected (same device for both LAN and Wi-Fi)
-
Device placed within 1–2 feet of the router during testing
Despite all this, the wireless bufferbloat remains severe. I suspect this could be a firmware-level issue, possibly lacking proper queue management on the wireless interface.
Test results:

Would appreciate any insights or confirmation from others using the Archer C64. TP-Link team—could this be addressed in a future firmware update?
Thanks,
Dipto

Hello @Dipto-K ,
Please note that it is available for the EU version.
I think the router you are using is the US version, which is why you cannot get a new firmware update notification.

@Joseph-TP Our bd support told that Archer c64 EU and US both sare same hardware. So, we can use that eu version firmware and from hearing this I flashed with the 1.15.0 which was available then on the page but I can't show it now.
