Hi Sir,
I have an ICX7150-C12 connected to an AT&T BGW210 gateway (flat network, no VLANs).
After a power outage, I experienced upload failures across all devices.
Both wired and Wi-Fi devices were affected with the same issue.
Download speeds remained normal (~900 Mbps), but upload was failing or very low.
Rebooting the gateway did not resolve the issue.
When I bypassed the switch (direct to gateway), speeds were perfect (~900/900).
Reconnecting the switch initially reproduced the issue.
After reseating cables, performance improved (~900 down / ~800+ up).
Concerned this may be a port negotiation, duplex, or firmware issue.
This impacts all devices and needs urgent guidance on stability tuning and fix.
Appreciate it!
