[No Power / Failed Power Adapter]
The router or networking device shows no power LEDs after being connected. GigaFast documentation identifies either the external power adapter or the hardware itself as the likely failure.

End Use Segment
GigaFast Ethernet is a Taiwan-based OEM/ODM electronics engineering and manufacturing company specializing historically in networking and powerline communication (PLC) equipment. It designs and manufactures products such as Ethernet/powerline bridges, HomePlug and HD-PLC networking devices, industrial Ethernet/PLC solutions, network switches, and customized communications hardware. More recently, its engineering and manufacturing capabilities have expanded into industrial and automotive electronics, including vehicle telematics, IoT hardware, and wireless-charging solutions. GigaFast provides mechanical, PCB-layout, and electrical engineering along with procurement, testing, prototyping and production services. The company says global telecom providers account for roughly 90% of its business, with Taiwan used for prototypes and smaller production runs and Jiangxi, China used for mass production.
2 Most Seen Failures:
[Intermittent Connection Drops]
The router or switch periodically loses network connectivity and requires a power cycle to recover. This behavior has been reported on EE400-R routers and EZ800-S switches, in some cases progressing from occasional outages to complete failure.
[Ethernet Port / Link Failure]
An Ethernet port fails to establish a link, leaving its link LED off despite a connected device. Possible causes include a failed port or interface, although cables and the attached network adapter must first be excluded.
[Severe Packet Loss]
The switch establishes a connection but drops a substantial portion of network traffic. Reports involving the EE500-S describe repeated ping timeouts even though local connections through the switch remain operational.
[Speed or Duplex Negotiation Failure]
A 10/100 switch may negotiate an unexpectedly low speed, fail at 100 Mbps, or exhibit unstable communication because of duplex or compatibility problems. EZ500-S, EZ800-S, and EE500-S documentation/reports contain examples of speed and duplex-related connectivity issues.
[Overheating / Detached Heatsink]
The switch can become unstable or stop functioning when cooling of its switching chipset is compromised. One documented EZ800-S failure was traced to its chipset heatsink coming loose, allowing the chip to overheat.
[Internet Connectivity Failure]
The device powers up and may establish local Ethernet links but connected computers cannot reach the Internet or other expected network destinations. This symptom appears in GigaFast router and HomePlug troubleshooting documentation.
[Port Forwarding / Application Connectivity Failure]
Internet browsing works, but games, hosted services, VPNs, or other applications requiring specific inbound connections fail. EE400-R documentation and user reports describe problems involving application compatibility, VPN ports, and virtual-server/port-forwarding behavior.
[Powerline Link Failure]
HomePlug adapters fail to establish a powerline connection, indicated by an absent powerline/network LED or inability to communicate with other adapters. GigaFast documentation notes outlet conditions, electrical noise, network configuration, and adapter faults as potential causes.

- 1 Repairs are performed on a best-effort basis. Acme Revival utilizes a network of sophisticated technicians and engineers with diverse service offerings; despite this, factors that influence the repair outcome may ultimately prove unsuccessful. Acme Revival makes no claim that it can, guarantee a repair before your device is sent in for diagnostic evaluation; even then, repair and diagnostic work are not mutually exclusive. Despite well-intentioned quoting, repairs may still prove unsuccessful.
