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

I have this model in my home and in my parents home. I have now had the Port 1 failure at both locations. Mine eventually started working again after going through the long painful "RMA" process, which was simply them sending me a refurbished unit that was equally defective. I have no answer as to how mine started working again. Just today, my parents unit failed on port 1. It was after a power outage. TP-Link has lost a customer if they don't recognize this as a widespread issue and do the right thing.

@AGMV Yep, same issue here. Port 1 died on my main unit a few months ago and now port 1 died on my satellite tonight. Spoke to customer service and they said its eligible for RMA if I can find the recipt from more than a year ago. Not looking good for getting it replaced and I didnt know it was this widespread. Going to stop recommending them to people.

Just had ANOTHER port 1 failure of an X75 satellite unit after I had to turn the power off to the upstairs of the house. If these units can't handle being turned off suddenly and they don't have a power button then they are not fit for sale.
I'm going to look into getting a refund.
