Deco XE75 port 1 no longer working
Good day. A few months ago lost my internet connection and after no luck debugging the issue I simply swap my ISP ethernet cable from port 1 to 3
- Before swaping: Port 1 ISP. Port 2 Deco Secondary unit. Port 3 Switch
- After swaping. Port 1 Switch. Port 2 Deco Secondary unit. Port 3 Switch
Several weeks later there were some power outages due rain & wind. Internet and Deco units recovered but devices connected to switch were no longer accesible
- Removing the swicth and connecting the device (example. laptop) to port 1 didn't fix the issue (no switch issue)
- Ethernet cables working as intended (neither failure here)
- Attempt several scenarios (cant recall them) but ultimately only port 2 & 3 were working as intended
Upgrading to 1.2.6 didn't fix the issue and just yesterday I update to beta firmware 1.2.7 with promising results yet still issues
My results
- 2 XE75 Deco units
- Device and connection seems stable. No performance or disconnection issues so far
- Ethernet port 1 is empty, port 2 goes to a switch, port 3 goes to ISP
- Port 2 switch has on it: 1. Ethernet connection to Arlo hub station (security cameras), 2. Ethernet connection to network HDD, 3. Ethernet connection to another Deco XE75 unit
- Main Deco Working scenarios
- Scenario 1: Port 1 empty. Port 2 switch. Port 3 ISP. Secondary Deco working as intended.
- Scenario 2: Port 1 empty. Port 2 ISP. Port 3, switch. Seocndary Deco working as intended
- Main Deco NOT working scenarios
- Scenario 3. Port 1 ISP. Port 2 switch. Port 3 empty (no IP, red light, no internet)
- Scenario 4. Port 1 ISP. Port 2 empty. Port 3 switch (no IP, red light, no internet)
- Scenario 5. Port 1 switch (w/o Deco unit). Port 2 ISP. Port 3 empty (there's internet, Secondary Deco works, but whatever is connected to the switch will be unaccessible)
- Scenario 6. Port 1 switch (w/o Deco unit). Port 2 ISP. Port 3 Secondary Deco unit (There's internet, Secondary Deco works as well but devices connected to switch are unaccessible)
- Scenario 7. Port 1 switch (w Deco unit). Port 2 ISP. Port 3 empty (There's internet at first, but after a few minutes the whole internet will stop working, including internet WiFi)
- In brief
- Whatever is connected to port 1 is NOT detected by Deco App
- Whatever is connected to port 1 will not have internet
- If there's another Deco unit connected to port 1 via a switch it will likely crash the Internet at all, including WiFi
After this, did swap Deco roles
- Working scenarios (Main Deco, used to be Secondary)
- Scenario 1: Port 1 empty. Port 2 switch. Port 3 ISP. Secondary Deco working as well
- Scenario 2: Port 1 empty. Port 2 ISP. Port 3, switch. Secondary Deco working as well
- Scenario 3. Port 1 ISP. Port 2 switch. Port 3 empty. Secondary Deco working as well
- Scenario 4. Port 1 ISP. Port 2 empty. Port 3 switch. Secondary Deco working as well
- Scenario 5. Port 1 switch. Port 2 ISP. Port 3 empty. Secondary Deco working as well
- Scenario 6. Port 1 switch. Port 2 any device. Port 3 ISP. Secondary Deco working as well
- Secondary Deco (old Main Deco) WORKS if connected via port 2 or 3
- NOT working scenarios
- Old main deco (now secondary deco) NO working if connected via Ethernet port 1
Looks like Ethernet port 1 is my issue... Any way to figure out the root cause? Port no longer working? Really doesn't make sense that only 1 port is no longer working

@AGMV Same problem here with hardware version EU/V1 and firmware version 1.3.2 BUILD 20240119. Port 1 of the main DECO XE75 unit suddenly stopped working, this setup worked for nearly one year without issues. A hard reset of the main unit did not solve the problem and during the night ip address was assigned to my Tado Gateway which is conected to the main deco pod on port 1. Devices which were connected to port 2 and 3 seems not affeted and funtion properly. Now it works again it seems not hardware related but firmware related. There are so less debugging options in this device so its not possible to pinpoint the exact problem. TP-LINK support please help!!!

@AGMV At this point a recall/extended warranty is needed for XE75. TP-Link please address this issue!
My port 1 has been dead for more than 6 months now! And I always thought it was my Mac's problem. I can't believe this post existed for so long.
At this point most of us are reaching the end of warranty. I'm starting a RMA process but who knows when the replacement unit will fail.
TP-Link should either recall all these failing units, or extend the warranty of all XE75, as this PORT 1 NOT WORKING ISSUE is such a widely seen problem.

@LJXXXD I bought the 3 pack in December 23 and in the last 2 weeks in all three xe75 the first port died.
I called the support and they told me, after several tests, that I must change everything.
I
am
not
happy

Same. Two XE75s with port one not working on either.

Very frustrating issue. I am posting merely to log the issue. I have a large network with many switches involved (all TP-Link equipemnt). I too got connection without IP address distribution. Didn't realize it was port 1 but that sounds currect. After a lot of playing and effectively using ports from switches and Deco units, I was able to get everything to work again. (2) of my 3 XE5300's were affected (i.e. no LAN port 1).

Same issue here. after 7 months of no problem port 1 just died on my main deco ( have 2 units hardhaul connected)

Posting about the same issue. Today my XE75 main unit's Top port stopped working. Can not be used for anything anymore. No ethernet backhaul, no WAN, nothing.
Really frustrated about this, since I bought the unit recently, and even if I get a warranty unit, I suppose the issue will come back later on.

Hi, Thank you very much for the feedback.
I think you could email the local technical support to see whether they can upgrade the model to a different version.
Thanks again and best regards.

@AGMV Same with me after troubleshooting all night last night, I isolated it to port #1 on my XE75. extremely frustrating to deal with.

Just wasted a couple hours to figure out my Deco XE75 V1.0 port 1 stopped working.
How is this even possible?
I've never experienced an ethernet port failure in any device I've used in my life.
I hope the other ports survive for a few more years, but this is unacceptable.
And yes I did try to update the firmware, but this is probably a hardware issue.
I guess my next network upgrade will be with another brand.
