Hello everyone.

I'm using 2x CPE210 v3.20 on my home for wifi bridge to my moms home. Installed with high quality outdoor Cat7 with grounded to patch panel at home because its installed roof of apartment. Mounted on long plastic pipe. Also grounding screw attached too. Working over 4 months. But suddenly it stop working. Cant ping or web access. Couple unplug and replug didnt make difference. Link light on switch is indicating lan connection. Then I started TFTP method by reset button one PoE injector while power cable plugging. Used same firmware version inside of if. CPE210(EU)_V3.2_2.2.3 Build 20201110

I did lots of TFTP on devices like Ubnt, TP-Link and lots of more. On my first attempt it successfully downloaded recovery.bin from 192.168.0.100 and restarted itself (I mean I watch just link light on switch). After almost 20 minute no link light come back. So I made couple replug and unplugs power and some times it just light up 2 or 3 times for just half of seconds blinking then goes no link light on switch.

Then I retry TFTPD. Everytime its download whole package. I tried ubuntu and windows TFTPD and 3 different computer. Everytime its finish but after reboot no link light. So I had to remove CPE210 from roof and on table its same. No link light normal startup. Links only works on TFTPD mod. But 10Mbit Half Duplex on TFTPD. I dont know is it normal for TP-Link. Never realized before. I try different switch and directly attach to computer without switch. Didnt make any difference.

It still under warranty but due pandemic its hard to get it RMA on my country and replacement maybe required some more weeks. I dont wanna open it for Serial U-Boot recovery but if you guys and suggestions I'm here te listen one more try before get it back to RMA.
