I am seeking a refurbished small business router recommendation that can meet the demands of a 50-client network. The router will be used as an access point and will need to support high-speed internet connections. I am considering the EdgeRouter ER-X, which has some impressive features including support for VLAN and IPsec. However, I am concerned about its configuration being a bit outdated, and I am uncertain whether it can handle VoIP and VoWiFi. Additionally, I am looking for a reliable and user-friendly router that is easy to set up and maintain, with a budget of around $300. I am open to considering options from other manufacturers as well.
