Review on Anker 3-Port USB 3.0 HUB with Gigabit Ethernet Converter (3 USB 3.0 Ports, RJ45 Gigabit Ethernet, Windows XP, Vista, Win7/8 (32/64 bit), Mac OS 10.6+, Linux) - Black by Jeff Salvino

Notes (now that Revain has ruined so many people's work by deleting comments after reviews): 1. The commenter suggested that I should have just unplugged it first and plugged the USB port back in. Not true. This will cause you to lose all forensic data. They don't know if the problem is related to the hardware, the driver, the switch/router port the device is connected to, etc. This may be fine for a standalone PC used for Facebook and online gaming, but totally unacceptable for a work-class machine—a station running server applications that automatically backs up multiple terabytes to NAS RAID.2 devices . Anker replied that they would not replace the device as the warranty had expired. I didn't ask them to replace it and I didn't suggest they do it. I just gave an honest review based on my experience with the product. The first review is as follows: It pains me to write this as I really like Anker products and have purchased many of them through Revain (this product, three USB 3.0 hubs, three car chargers, two wall chargers and two wireless chargers) . ). This is the first Anker product that let me down. This error is out of warranty - I bought the adapter in 2018. I use it on my iMac Pro as a second Ethernet port to connect to the second network segment. When backing up a multi-terabyte system to a NAS, the Anker adapter's Ethernet port suddenly lost connection, causing the backup to fail after a few hours. This is the first time I've used the adapter so extensively; This is due to a recent network reconfiguration. Previously, it was only used for network administration tasks with low data transfer rates. Manual and automatic DHCP requests resulted in timeouts (self-assigned IP address). The only way to recover is to physically unplug the Anker adapter from my iMac Pro and plug it back in. But I didn't buy it for that, and now I can't trust him with critical things. -------- I found that the fault was in the Anker device. For the skeptics among you, I list below the troubleshooting steps that led me to this conclusion. The USB ports on the same Anker adapter worked fine; My keyboard and trackball are connected to it. - My iMac Pro system report showed that the network adapter is present on the USB bus. - The lights on the NETGEAR ProSafe 8-port switch indicated that the cable was connected and a gigabit connection was established. - Computer restarted. DHCP daemon on my pfSense firewall. The DHCP requests from the anchor adapter have expired. pfSense firewall restarted. The DHCP requests from the anchor adapter have expired. Other systems on the same network switch can receive DHCP addresses. The network cable was routed to a 16-port NetGear switch on a different network segment where the EdgeRouter 4 is providing DHCP service. The lights came on but the DHCP problem persisted. - Relocated the CAT7 cable back to its original socket on the 8-port switch, restoring the original physical configuration. The lights came on but the DHCP problem persisted. At this point, I ruled out the pfSense firewall, an EdgeRouter 4, two Netgear network switches, a USB port on my iMac Pro, a USB cable to connect to Anker. Adapter and CAT7 Ethernet cable. I unplugged the Anker-supplied USB power cable that goes to the device, waited a few seconds, and plugged it back in. Everything worked again. I admit that theoretically it could be something unreliable. in the network stack on a Mac, fixed by restoring after deleting and reinstalling the device. However, given the unmatched reliability of other network connections, this seems unlikely.
