BE550v1 - Bugs, Errors, problems & other issues
Hello Everyone,
I create topic where we can share our problems with BE550v1 router, report bugs or other issues.
Maybe when there will be more of us they are finally going to fix something in future firmware updates.
First i will share bugs/problems what i notice while testing almost 2 months.
1. All official firmware is "buggy", makes WiFi unstable/drop or make network disconnections even the newest firmware 1.0.9 Build 240521.
To fix it you need install beta firmware 1.0.9 Build 20240429 rel.749 (i got it from TP-LINK engineer on email) only that one works more stable then others from my testing.
2. BE550 has weaker WiFi signal compare to AX55 (i testing 2,4/5GHz band).
Advertising on TP-Link site saying the BE550 has more range, which is a lie.
Example of strengh dBi signal betweend this routers you can find by cliking HERE
3. BE550v1 WiFi 6GHz band strength its very weak and 10dBi less stronger then other BE550v1 2,4/5GHz bands.
Because of that on second room your 6GH'z connection drops 3/4x times.
Double/triple more speed you got on 5Ghz band. So 6Ghz its useful in same room, where stand router only.
4. Depends which firmware you install, your strength WiFi band its different the most noticeable is on 6GHz band.
Example you can find by clicking HERE
5. On the box of BE550 showing its a MLO triband (2,4/5/6) in option you can active only on 5/6 band.
Other advertasing lie to customer. Proof you can find by clicking HERE
6. USB storage bug. When you un-mark any folder in USB storage. All folders containing spaces between words also disappear.
7. When you connect BE550 + BE550 in backhaul easymesh system. Satellite router don't listen main router and put different channel width of WiFi on all band.
Example: I setup 20MHz channel width on 2,4Ghz band on main router but the satellite setup 40MHz. When i connect AX55 as satellite all work fine.
INFO:
For addition testing I bought second BE550, because i start afraid that my copy of BE550 make trouble. But now i know two of products what i own have the same issue. I hope they will fix problems in future updates...
But if this is a hardware problems they should recall all products and give us money back :( Because right now we are free beta testers of not finished product which we pay 300$ each.
EDIT:
Problem reported from other users:
1. Users confirm random disconnection Wifi network disconnection while using Firmware 1.0.9 Build 240521, 1.0.8 Build 20240226, 1.0.7 Build 20240119. 2. Weak WiFi Signal on 6Ghz band. 3. The router disconnects all network connections (wired and wireless) when the client connect to 6Ghz band by NCM865 device. Firmware 1.0.9 Build 240521. 4. When is activate MLO option, devices get random disconnect + is possible a critical hardware stuck, 6Ghz not visible or don't work anymore even from restart device or flash to other firmware. CRITICAL PROBLEM!

@ChrisBS after updating to 1.0.11 firmware I still having issues with BE550 losing connection constantly 2.4/5/6 band.

I'm updating the status of the new official firmware of the BE550 V1 and hope others can also install it to confirm if the overall performance will be improved.
The official version 1.1.1 Build 20241230 brings a range of improvements and new features to enhance your networking experience, offering better performance, security, and ease of use. This update is gradually rolling out, and users can check for updates on the BE550's web interface or through the Tether App and install the latest version. We strongly recommend upgrading to this version to improve the overall experience.

Summary
When an Archer BE550 is used as a mesh satellite node (wireless backhaul), its DHCP client enters an abnormal renewal loop, sending DHCP RENEW requests every ~30–40 seconds despite receiving a long lease time (several days).
This behavior can overload or destabilize some DHCP servers and is not compliant with normal DHCP client behavior.
Observed Behavior
-
The mesh node successfully receives a DHCP lease with a long duration (≈ 7 days).
-
Immediately after receiving the ACK, the node logs:
“1/2 lease passed, enter renewing state”
-
The node then renews the lease repeatedly every ~30–40 seconds.
-
This loop continues indefinitely.
Expected Behavior
-
DHCP renewal should occur at T1 ≈ 50% of lease time, not immediately.
-
With a multi-day lease, renewals should happen after several days, not seconds.
Key Evidence (from device logs)
Example pattern observed repeatedly:
receive ack from server with lease ≈ 600000 seconds 1/2 lease passed, enter renewing state send renew request
This indicates that the DHCP client miscalculates the lease timer.
Scope of the Issue
-
Occurs only on the mesh satellite node
-
The main BE550 (root node) does not show this behavior
-
Occurs with:
-
Wireless mesh backhaul (Wi-Fi 6/6E/7)
-
Smart Connect enabled or disabled
-
MLO enabled or disabled
-
-
The issue persists even with:
-
Fixed channels
-
Reduced channel width
-
Long DHCP lease times
-
Workarounds Tested
-
Using a static IP on the main node stops the issue for that device.
-
Mesh satellite nodes cannot keep a static IP (settings are overridden in mesh mode).
-
DHCP reservation on the server side keeps the IP stable but does not stop the renew loop.
-
Changing Wi-Fi performance settings may reduce frequency but does not fully fix the issue.
Impact
-
Excessive DHCP traffic
-
Potential DHCP service instability on some routers/firewalls
-
Difficult to diagnose unless DHCP logs are inspected
-
Affects advanced network setups more severely
Conclusion
This appears to be a firmware bug in the DHCP client implementation of the Archer BE550 mesh satellite node, where the lease timer is incorrectly evaluated, causing immediate renewal loops.
A firmware fix is recommended to correct DHCP lease timing logic in mesh mode.
