Hello,

Just wanted to give an update after further testing and a reply from TP-Link support.

Unfortunately, the problem still exists even after installing the latest firmware:

• Firmware version: 0.10.0 3.0.0 Build 250312 Rel.26205n

• Hardware version: VX800v v1.0

• Serial number: 224A5H4000791

•  

💡 Summary of the issue:
With just two devices connected (my laptop via Ethernet and my smartphone via Wi-Fi 6), I’m experiencing upload bufferbloat of up to 240 ms, sometimes more.
This happens consistently, even with minimal usage and low-bitrate content (e.g., YouTube in 480p).
 

🧪 Additional Observations (Real-world Testing):

• When playing online games laptop and on my Phone a YouTube video starts buffering (even at 480p), my latency spikes immediately – and drops back once the video is fully loaded.

• Same effect happens when my girlfriend scrolls through TikTok. Each video load causes a latency jump, visible even while I’m just browsing on my wired laptop.

• These tests were done with only two devices connected, no background traffic, no smart home devices, and using a Telekom DSL line (50/20 Mbit).

🧠 Possible Cause: Memory Usage?

When I first got the VX800v, the memory usage was about 40%. Now, without major changes, it’s often around 70%, and I’ve even seen it spike up to 89%.

I'm wondering if high memory usage or poor memory cleanup might affect QoS or packet handling – especially under low-latency scenarios like gaming or video calls.

📌 Official Support Contact

TP-Link support has been responsive and helpful, but unfortunately, no fix has been found so far. I've also shared all this information via email.

If anyone has received further updates or found a workaround, I’d be super grateful if you could share.

Thanks again
