Review on High-Performance UTT ER840G WAN Router With 4 Gigabit Ports For Businesses - Load Balancing, Failover, VPN, USB, & Access Control by Tony Elliott

I bought this to set up WAN failover between two ISPs at my house. Initial setup seemed straightforward, but as soon as I started navigating around the GUI the ethernet connection to my laptop would fail and all 5 ports would shut down - no activity lights and no connection response from any port, and it required a hard reboot to get back into the GUI. Happened every time I tried to set up the device even with nothing else plugged in except my laptop on the same subnet. Probably a hardware problem but do not want to deal with trying it again, so decided to go for the Trendnet TEW-829DRU, which is an all-in-one dual-WAN and AC3000 WiFi router. More money, but a much more streamlined setup for a home environment than separate SD-WAN and WiFi routers working in tandem.
