Model: VX800v  
Hardware Version: V1
Firmware Version: 0.9.0 3.0.0 v603c.0 Build 240926 Rel.39238n

Hey everyone,

I'm experiencing a serious issue with the new VX800 and was wondering if anyone else has found a solution – or at least received any feedback from the manufacturer.


I have a DE Telekom DSL connection (50/20 Mbit), I recently switched to the VX800, and while the hardware seems great overall, I'm running into massive bufferbloat on the upload using Ethernet or WIFI – hitting up to 240 ms loaded.


What’s strange is that my old DSL router Archer VR2100v, on the exact same line (no special QoS settings), had only about 70 ms upload bufferbloat. Both routers sync at  the same speeds (50/20 Mbit), yet the VX800 performs significantly worse +240 ms


This is really frustrating for online gaming and video calls. And unfortunately, the VX800 offers no options and yes, I’m already on the latest firmware (See below)


I’m hoping a future update will fix this issue. The hardware clearly has potential, but the lack of control over bufferbloat makes it hard to recommend.


Has anyone received a response from the manufacturer or ISP regarding this issue? Any workaround or official statement would be appreciated!


Thanks in advance!

That one is the newest firmware

 

https://static.tp-link.com/upload/firmware/2025/202504/20250403/VX800v_v1_0.10.0_3.0.0%20Build250312.zip

 

 

But doesnt solve the problem.

 

And boy, your problem is not your mean Latency . the maximum latency goes up to 700ms in your case at upload , according to your photo.

Thanks for pointing that out!

Yes, you're right – the average (mean) latency is bad enough, but the maximum upload latency spikes up to 700 ms, which makes pretty much unusable under load.

I’ve installed the latest firmware (Build 250312), but sadly no improvement so far.

Totally feel your frustration bufferbloat that high really kills gaming and calls Mepco online bill. Surprising that the VR2100v handled it better without tweaking anything. Sounds like the VX800 firmware still needs serious tuning.

Hi@DeRealMatteo  @jennyjack87 

Thank you for contacting our community.

 

VX800v is a customized device specifically designed for local Service Providers. Its software is tailored to meet the unique requirements of these providers, ensuring alignment with their specific needs. Due to the specialized nature of the firmware on your device, our ability to provide troubleshooting may be limited.
We can certainly offer some troubleshooting tips that may help resolve your issue. Please consider the following:
1. Enable QoS for Gaming;
2. Change to different wireless channels;
3. Try wired connection instead of wireless connection.
If the problem persists after trying these steps, we recommend contacting the technical support of your Service Provider who supplied the device, as they are best suited to provide the necessary assistance for your device.

Hi@SLKingX,

Have you been in contact with the local support or Internet service provider of the modem? If they have further updates, you are also welcome to share the solution here.wink

Yeah, exactly! It’s wild that the VR2100v did a better job without any QoS settings at all. Just plug and play – and way less bufferbloat.

I totally agree with you – I actually like the VX800v a lot too! Solid performance, nice design, and lots of potential. But yeah, there’s definitely more going on than just missing QoS/SQM.

What really puzzles me:
I only have two devices connected – my laptop and phone, that’s it.
No smart home, no TV, no torrenting, nothing heavy. So it’s kinda weird that there’s even anything to manage or prioritize. Just two connections... and still massive upload latency. 😅

Let’s hope TP-Link sees this and digs a bit deeper into the issue in future firmware updates!

  @Joseph-TP 
 

Thanks a lot for the reply and the suggestions.

Here’s a quick summary of what I’ve already tried:
 

  1. Enable QoS for Gaming
    I looked for QoS settings, I tried all available settings, but unfortunately no improvement.
     

  2. Change to different wireless channels
    I’ve also tested different Wi-Fi channels – again, no difference.
    Also, important to note: the issue occurs even on wired Ethernet, so Wi-Fi is not the cause here.
     

  3. Try wired connection
    Most of my bufferbloat tests were done using Ethernet on my laptop (Wi-Fi 6 capable, just like my phone).
    The problem shows up clearly on a stable wired connection.
     

I only have two devices in my entire network (Laptop and Phone), so it’s definitely not a congestion or traffic management issue on my side.
 

The strange part is that my old router (VR2100v) handled bufferbloat way better without any tuning. Just same line, same devices – and it worked. That makes me believe the issue is likely related to how the VX800v handles upstream traffic, or maybe something deeper in the firmware.

I totally understand the VX800v is customized for ISPs – but I hope this feedback helps, because the hardware is really promising otherwise!

Thanks again for your time and support.
Best regards

Hi@DeRealMatteo,

Thank you for your reply.

Sounds more like a performance issue with the Archer VX800v. I would recommend contacting your local support team or internet service provider to troubleshoot issues with this customized device.
