Review on Mikrotik RouterBOARD 951Ui-2HnD RB951Ui-2HnD: High-Power 2.4Ghz Wireless AP with 5x10/100 Ports and OSL4 by Dimitar Tsonov ᠌

They save in Latvia, like buying special boards. Type RB411UAHL, there are certainly no problems with this piece of iron, 2 pieces have been working for a year. Its pros: Multi-protocol, punchy directional WiFi, stable, huge functionality up to VPN, OpenVPN and more. Powerful firewall. Different cons: I plugged in a Yota 4G modem, it works without a usb extension cable, but not with an extension cable. I soldered my twisted-pair cord to 1m. The same . Voltage 4.92 instead of 5V. Those. Conclusion, very weak power at the USB output. Replacing the power supply with 24V 2A did not give any results.
