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

Happy to say that I have returned my XE75 system for a full refund.
I recommend that anyone with port 1 failures try to get a refund, as any replacements will also fail, but at a time where you have less consumer rights.
TP-Link have dropped the XE75 like a stone and seem unwilling to release new firmware.
I'll be trying to avoid TP-Link products in future.
Wish you all the best of luck!

I have the same issue with my Deco X95 (also three ports, of which the first/top one not working).
Is the company researching this port issue or not at all?
It is too late for warranty.
X95
Version: EU 1.0
Firmware: 1.2.5 Build 20240903 Rel. 50784 (latest fw)

@Delacrossa they don't care unfortunately. It's a shame because otherwise these have worked well for me. I am looking to upgrade to a wifi 7 mesh but don't trust and am not considering TP-Link at all

@port1 I went with the 3-pack Deco BE11000 from Costo to replacae my XE75 and have to say its orders of magnitude better.

@jacobh101 I gave away all my XE 75 units and switched to UniFi. What a game changer as I haven't had an issue since. I won't be purchasing a tp-link product again in the future as I find their tech inferior to other companies.

You can add one more unhappy customer to the pile. Bought a 2-pack of XE75 to use as main router and one mesh node along with three X50. All the units have been working flawlessly until last year when one of the XE75 units in my home office sporadically started blocking anything connected to port 1. This got worse and worse until port 1 could not be used at all. Hoped I would get it replaced under warranty but instead they reimbursed me for both of the units even though I was allowed to keep the working one. Nice win for me I thought until this week when exactly the same is happening to port 1 on my other XE75 unit.
I'm happy with the system otherwise and it has been much more stable then other systems I've tried throughout the years. Really loved my old Ubiquiti AmpliFi system I had before but it got to old and quite expensive to replace. Let's see if I buy another Deco unit or switch system once again.
