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

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.

I also have the port 1 failing on two different units. The ports failed months apart and i can luckly workaround the problem using a switch.
However because the 2nd unit now also failed, i am afraid the 3rd one will fail too. Looking at all the reported problems in this and other threads clearly this looks like an hardware issue and TP Link should help fix this asap? I am with a 3 year warrantee (retailer) so can i just swap the units for working ones? How do report this ? Seriously doubting to continue with the TP Link infrastructure because of this.
Hardware version EU / 1.0 and now latest firmware (port 1 on each unit failed randomly and not related to any update)
Bought the 3 unit set in May 2023

Hi guys as mentioned in my earlier post. I have raised the issue for Tp link to exchange the defective unit but no feedback from them directly. I recently removed all my tp link units and moved over to Ubiquiti. All I can tell you they is no comparison. Best part not once have I had to raise a issue with technical department as everything just works perfectly.

Well, here comes another confirmation.
Yesterday my Hue Bridge stopped working and I started troubleshooting. I saw DHCP discovers coming from the Bridge, my DHCP server sent back offers, but then no DHCP requests came in. This was driving me crazy and I did quite lengthy troubleshooting including switching the DHCP server (well, now at least I got used to Kea), cause as I saw packets coming from the bridge, I did not assume a hardware issue.
Long story short, the bridge was connected to ETH port 1 of my main Deco. Switching to another port finally solved the problem after some hours of trial and error. As I used all ports of that Deco, I even attached a hub to bundle two devices on port two now. No issue. For sure I unfortunately had the idea of googling for reports of a faulty ethernet port on a Deco not before it turned out it is a faulty ethernet port.
I do not know what testing is done at TP-Link, but seeing that there are packets coming from that port but just don't seem to be accepted when arriving at that port (at least in my case), I wonder if it really is a hardware issue or if there still is a chance to get that fixed by some firmware update.
Best

Same falure (port 1 is dead in one of the XE75 nodes) for me, noticed that some parts of the network dident work after some troubleshooting did i manage to get the node up using another port.
Using the latest firmware 1.4.1 Build 20240722 Rel. 60491
Hardware version: 1
Any reports of issues on hardware version 2?
@David-TP, If this issue is related to hardware version 1, I strongly suggest that TP-LINK consider a recall. This would ensure that TP-LINK maintains its customer base and avoids dissatisfaction among those who have invested in these products.
I look forward to TP-LINK addressing this concern and doing the right thing.

I swapped the units with the retailer i bought it from. Everything is now working again. Because i received the new units before i sent back the faulty ones I could do a complete replace keeping my current configuration without restoring a backup by swapping the units one by one and switching the main deco unit in the end.
Unfortunately I received Hardware version EU / 1.0 so if the problem comes back i will report in this topic.
