Firmware Version:

Hello TP-Link Community / Support team,

 

I am experiencing a very specific and frustrating upload speed issue with my new Archer BE550 (Wi-Fi 7) router, and I believe it is a firmware compatibility bug.

 

My Setup:

* ISP: Airtek Solutions (Venezuela) - Fiber Optics (1 Gbps Symmetric plan).

* Router: Archer BE550 (BE9300).

* My Device: POCO F5 Pro (Wi-Fi 6 capable, Snapdragon 8+ Gen 1 chip).

* Comparison Device: Redmi Note 11 (Wi-Fi 5).

 

The Problem:

When my POCO F5 Pro connects to the 5 GHz band, the download speed is amazing (around 900+ Mbps), but the upload speed is strictly capped and stuck at 93-94 Mbps. It never goes higher, behaving as if there is a 100 Mbps link-rate limit or an aggressive QoS rule applied specifically to my device's upload traffic.

 

Troubleshooting already done:

1. Cross-device testing: A Redmi Note 11 (Wi-Fi 5 device) on the exact same 5 GHz network easily surpasses 200+ Mbps upload. 

2. Band testing: If I connect my POCO F5 Pro to the 2.4 GHz band, the upload restriction disappears, and it unblocks, reaching over 105-161 Mbps upload.

3. Router Settings: I have completely factory-reset the router. Parental Controls are off, QoS is default, and no bandwidth limitations are configured in the Tether App. 

4. Wireless modifications: I tried changing the 5 GHz mode from "802.11a/n/ac/ax/be mixed" to "802.11a/n/ac/ax mixed" (disabling Wi-Fi 7 protocols) and reducing the channel width to 20/40/80 MHz. This briefly allowed the upload speed to peak at 123 Mbps, but it eventually drops back down or remains unstable compared to the 900 Mbps download. Turning off OFDMA/MU-MIMO didn't help either.

 

There seems to be a specific handshake/protocol bug between the Archer BE550's Wi-Fi 7 firmware features and the Wi-Fi 6 (ax) chip on certain Xiaomi/POCO devices when managing upload streams on the 5 GHz band.

 

I would highly appreciate it if the engineering team could investigate this compatibility issue. I am willing to test a Beta firmware if available to resolve this bug. 

Thank you in advance!

Hello @Jdgmz7 ，

Welcome to our community.

 

This anomaly appears specific to the POCO F5 Pro on 5GHz (while the Redmi Note 11 performs well). This could potentially be related to the device's Wi-Fi 6 implementation or driver behavior. 

 

 

Here are some suggestions that may help:

  1. Disable Smart Connect to ensure that 2.4GHz and 5GHz have separate SSIDs to avoid automatic switching interference.
  2. Fixed Channel (Avoid DFS Channels): Manually select a non-DFS 5GHz channel, such as 36, 40, 44, 48 (low-frequency band) or 149, 153, 157, 161 (high-frequency band). It is recommended to try 44 or 157 first.
  3. Enable Guest Network 5G separately for the POCO F5 Pro:
  • Set a separate SSID, such as TEST_5G_AX_ONLY;
  • Set the wireless mode to 802.11a/n/ac/ax mixed or Wi-Fi 6 only (avoid "be");
  • Fix the channel bandwidth to 80 MHz (for optimal stability, avoiding potential scheduling issues with 160MHz);
  • Use WPA2-Personal for security encryption.

Re:Archer BE550 - Upload speed capped below 100 Mbps on Wi-Fi 6 device (POCO F5 Pro)

  @Joseph-TP got the same issue after updating to latest firmware.

 

​I am alao experiencing a severe upload speed throttling issue on my Archer BE550 V2 immediately following the installation of the latest firmware (1.3.1 Build 20260403 rel.18661).

​

My upload speed is currently hard-capped at 275 Mbps. Prior to installing this specific firmware update, my upload speeds were consistently above 850mbps. I tested using a direct LAN connection with a confirmed 2.5 Gbps link speed to the BE550. The upload speed in the speed test still caps at 275 Mbps.

 

​The mesh unit on the network is completely unaffected. Testing through the mesh unit yields upload speeds of 850 Mbps.

​

I bypassed the BE550 and connected directly to my Globe ISP router. The upload speed remains a consistent 850 Mbps.

​

Because the Globe ISP router and the mesh unit both maintain normal 850 Mbps upload speeds, the bottleneck is directly isolated to the Archer BE550 V2 main unit and seems entirely tied to the recent firmware update.

​Please advise on a permanent fix for this bug, or provide instructions on how to safely roll back to the previous stable firmware version so I can restore my network's upload capacity.

@Hector25 

Hi everyone,

I'm glad to see I'm not the only one facing this issue. I am experiencing the exact same upload speed limitation with my Archer BE550 and my POCO F5 Pro after the update.

Since this clearly seems to be a bug in the latest firmware version, do you know when a fix will be released? If there is a beta firmware available that solves this problem, could you please share it with us?

Thank you!

Hello  @Jdgmz7 ,

Thanks for getting back to us.

 

May I know the internet plan of your network? 
Which firmware version were you using previously? What was the upload speed on the POCO F5 Pro with that previous firmware version?

 

The tech team has been made aware of your case; they will likely reach out to you via email to continue troubleshooting. Please check your email inbox and confirm.

Hello @Hector25 ,

Thanks for contacting our community. 

 

Your situation does not appear to be exactly the same as dgmz7 's. Is the drop in upload speed affecting only a single device, or are all devices connected to the main router experiencing this issue? Specifically, which clients are you using to test the speed? Do these test results refer to the wireless connection, or do they cover both wireless and wired connections?

 

You also mentioned that you have a mesh unit; what is the specific model? Is it also a BE550? May I know if your network topology diagram is as follows:

ISP modem—router )))((( client devices

(Note: — stands for wired connection,)))((( stands for wireless connection )

  @Jdgmz7 I flashed back to the old firmware using recovery mode because the new one wouldn't let me downgrade. After I successfully downgraded, my upload speed went back to normal, both on Wi-Fi and LAN. I'm really wondering why they pushed that firmware to production with the upload issue affecting network speed performance.

@Hector25 

 

Would it be convenient for you to provide the following information? We have noted that you successfully downgraded the firmware; this indeed appears to be strongly correlated with the firmware update. We have already reported this anomaly to the relevant department, and we expect to receive a response shortly, which I will share with you here as soon as it becomes available.

  @Joseph-TP 

 

The upload speed affects LAN and WIFI devices connected to BE550 but not on BE220 (mesh)

 

Topology

ISP Modem/Router — Main Router BE550 [ — PC & )))((( Gadgets ]  — Mesh BE220 [ )))((( Gadgets ]

 

in BE550:

WIFI devices at 5ghz and 6ghz capped at 90-98 Mbps Upload (ISP max upload speed is 850 Mbps)

LAN at 2.5Gb port capped at 275 Mbps Upload (ISP max upload speed is 850 Mbps)

  @Joseph-TP 

 

Dear TP-Link Support Team,

Thank you for escalating my case to your senior engineering team.

I have performed a definitive cross-test that isolates the root cause of the upload speed issue. I tested my symmetrical fiber internet connection (provided by Airtek Solutions, roughly 1Gbps) using two different routers under the exact same environment and client device (POCO F5 Pro).

Here are the undeniable results (I have attached screenshots for your review):

Test with my old Wi-Fi 6E Router (Linksys): As shown in the attached Image 1, the device achieves excellent performance with 848 Mbps Download and 826 Mbps Upload.

Test with the Archer BE550 (Wi-Fi 7): As shown in the attached Image 2, while the download speed remains fine at 944 Mbps, the upload speed gets strictly capped at 84.8 Mbps.

This drop to an exact ~10% threshold strongly indicates a firmware-level cap or negotiation bug introduced in the latest update (version 1.3.1 Build 20260403), as other users in the community forum have recently reported identical behavior after upgrading.

I have attached Image 1 and Image 2 to serve as proof for the engineers. Please let me know if you need me to pull any specific system logs or if there is a Beta firmware available that addresses this specific upload throttling issue.

Looking forward to your guidance.

Best regards,

Jose
