@David6479 it could be beta firmware. But this is what tp-link tech support send me to email. I didn't look closer detailed.

  @INTRASERVERNET I've logged in to my router and had a quick check with mine and its the same as what I've got. Had this firmware since release and been running great for me and what I've been using it for:

3 PC's (Ethernet)

iPhone14 and S24

2 PS5's (Ethernet)

2 Firetablets

Nvidia Shield Pro (Ethernet)

5 FireSticks (Ethernet)

Various other Wi-Fi things all at once but all good.

Also using AX73 as a Satelite mesh with ethernet backhaul. 

I've been very happy with this router.

This firmware appears to have a bug in the Norwegian translation, it is showing Dutch (?) in some places. Btw, i have wifi7 currently disabled as I don't have any such clients...

Same issue here, one of my devices (Tado internet bridge) that's connected to the internet via ethernet has stopped working, it is also confirmed to be 10mbps half duplex which was working until I upgraded today to 1.1.1, so now I can't control any of my smart heating anymore as I have no idea how to connect this device to internet now. Why? When will this be fixed or reverted?

  @Kevin_Z 

What's worse I can't even downgrade the firmware to get it working again, I'm literally stuck with no way to access my heating because engineering decide to try to fix something that's not broken cmon guys...

Hey. I back from Holiday and do some testing of new firmware.

Unfortunetly after firmware upgrade, USB Storage its bugged even more :) This things what happen now blow my mind LOL ^^

1. I lose permission to already created folders and files inside them (i cant delete them, cant rename) also i cant send new files inside these folders on connected disk. Only is possible open them or copy them.

(to fix it i had to copy all data to other device, create a new folder on USB Storage and send it back)

WARRINING! Its there more extra bug. When I send back files, and copy whole folder with files inside to USB STORAGE DISK . USB STORAGE save only empty folder with 0kb files inside it. So I need copy just files one by one.... 

Also when I try send files even to new created folder or other localization,  pop up the information  "files already existed" LOL

To save it I have to click "rewrite it" other wise will be 0kb.

2. I can't make new folder or send files direct on USB storage disk when i unselect any folder/subfolders  from File-sharing. Only possible is make a new folder/sub-folder or send files when you enter to showed folder. 

3. File sharing after refreshing always showing all fodlers as unselected even if they were selected and saved.

4. Problem with speed with BE550 in AP easymesh mode connect to main router BE800 by WLAN.

I cant reach 2Gb's Internet speed, i notice i reach speed around +/- 100MB's down/upload.

Same upload/down from USB storage connected to device.

BE550 satellite easymesh WLAN - link speed connection with main router BE800 shows 4Gb's speed via 6Gh'z band. So speed should go near 2Gb's without problems. 

Of course same connected disk to main BE800 or BE550 in AP easymesh mode Ethernet backhoul work normal.

  @ChrisBS I agree with this what you mention and added in your post. Same issue with copying files.

  @INTRASERVERNET 

Thank you for feedback, im glad im not the only one with these problems ^^"

Before the update, the Liftmaster 828LM was connected directly to one of the LAN ports on the back of the BE550. The 828LM was listed as one of the connected clients on the older firmware.

 

After the update, the 828LM did not get an IP address from the BE550 when directly connected to it (i.e., the green status light on the 828LM does not stay on to indicate successful connection to the Internet). The 828LM is not listed on the connected clients list with the current (1.1.1) firmware.

 

There is no official documentation from Liftmaster specifying what LAN speed(s) it supports when connecting with the Ethernet cable. When I connect the 828LM on one of my old laptops (Thinkpad T430) with an Ethernet port, Windows 10 specified that the connection speed was 10 mbps. There is a Reddit thread (https://www.reddit.com/r/homeautomation/comments/kbd4j3/828lm_myq_no_longer_connecting/) that reports similar 10 mpbs Ethernet connection when connected to another device.

 

Similar to @snapper1357s Problem, I’m experiencing some frustrating connectivity issues with my TP‑Link Archer BE550 V1 router following the update to firmware version 1.1.1 Build 20241230 rel.20267(4555). Before the update, both my devices – the Tado Smart Home Bridge (connected via LAN) and my LQ Washing Machine (connected via Wi‑Fi) – worked flawlessly. However, since updating, neither device is being recognised.

Details of the Issue:

• Tado Smart Home Bridge (LAN):
  The Tado Bridge is no longer detected when connected directly to one of the router’s LAN ports. The status light, which previously indicated a successful connection, now fails to stay lit and it is not listed in the router's settings. I have verified that the bridge and the Ethernet cable work correctly when connected to other devices.

• LQ Washing Machine (Wi‑Fi):
  My LQ Washing Machine, which relies on a Wi‑Fi connection, is also experiencing connectivity issues. It is not successfully connecting to the router’s wireless network, and I suspect it is not obtaining an IP address as it once did.

What I’ve Tried So Far:

1. Basic Troubleshooting:
   I’ve tried swapping Ethernet cables and switching LAN ports for the Tado Bridge. For the LQ Washing Machine, I ensured that it is set to automatically obtain an IP address. Unfortunately, neither device has regained connectivity.

2. Firmware Downgrade Attempts:
   I attempted to downgrade to previous firmware versions (including 1.0.12 and 1.0.11). However, each attempt resulted in an “Upload error” across multiple web browsers (Safari, Chrome, and Firefox).

3. Consultation with TP‑Link Support:
   I’ve reached out to TP‑Link support and followed their initial troubleshooting steps, which included checking cable connections, LAN port options, and IP configurations. Despite this, the issue persists and no clear resolution has been offered.

Additional Observations:

• Both devices worked perfectly before the firmware update.
• The issue seems directly related to the new firmware release.

Has anyone else encountered these issues with the TP‑Link Archer BE550 V1 after updating to firmware 1.1.1, particularly with devices connected via both LAN and Wi‑Fi? Any advice, workaround suggestions, or insights into whether a firmware patch might be forthcoming would be greatly appreciated.
