eap773 ethernet failure after some times
I have an EAP773(EU) v1.0 on firmware 1.0.14 which is connected to an aruba 6100 CX serie switch.
The AP works fine for some times, but after about a week, I start seeing increasing error rate on the switch side:
Statistic RX TX Total ---------------- -------------------- -------------------- -------------------- Packets 75556420 174930246 250486666 Unicast 74483256 169336996 243820252 Multicast 310057 4702404 5012461 Broadcast 763107 890846 1653953 Bytes 13840444108 232380417494 246220861602 Jumbos 452900 93707376 94160276 Dropped 0 0 0 Pause Frames 0 0 0 Errors 10093 0 10093 CRC/FCS 8524 n/a 8524 Collision n/a 0 0 Runts 1555 n/a 1555 Giants 14 n/a 14
At this point, the EAP773 become unusable with very high packet loss.
After rebooting the EAP (using POE power cycling on the switch), the AP reboot and works fine for a few days/week.
I have multiple TP-Link omada AP, but only one EAP773 so I cannot compare, other TP-Link AP does not show this problem.
For completeness, here is the powe info for the port after a reboot, while in working condition:

I didn't think of copying it when it is in the "bad" condition, but I will next time it happens.
Hi @kuon
Thanks for posting here.
At this point, the EAP773 become unusable with very high packet loss.
>>> What do you mean specifically by saying unusable? Please give us more details about the situation.
for example, what's the LED status at this point? Can clients connecting to the EAP and get internet access?
What's the firmware version of your EAP773? What's the model number of your other EAP units? How many EAPs do you have in total?
The EAP773 requires approximately 24.5W of power to maintain normal operation. Please verify whether the total power consumption of all clients connected to this switch has reached its upper limit.
Additionally, network cable quality may affect performance—try replacing it with a shorter cable for testing purposes.
