| Flash | 16 MB |
| OS | D-Link |
| Power supply | 12 V / 2 A |
The Qualcomm Atheros QCA9558 @ 720 MHz CPU provides processing power. It handles tasks and services within the DIR-855L router. The 128 MB of RAM enables the router to handle multiple tasks and processes concurrently. Flash memory retains its data even when the router is off. This allows the router to keep its firmware and settings across reboots. The firmware upgrade process may vary depending on the router model. However, it often involves accessing the router's web-based administration interface. The D-Link packages the DIR-855L router with 12 V / 2 A PSU.
Network
| Protocols | IPv4 IPv6 |
|---|---|
| LAN ports | 4 x 10/100/1000 Mbps |
| WAN ports | 1 x 10/100/1000 Mbps |
| Mobile network | no |
| VPN support | no |
Like many modern routers, the D-Link DIR-855L supports many features and tech. They improve your network's connectivity and security. The IPv4 uses 32-bit addresses, represented as four sets of numbers separated by periods (e.g. 192.168.0.1). The router also supports IPv6. This allows you to use the latest Internet Protocol. Gigabit Ethernet ports support data transfer rates of up to 1 gigabit per second (Gbps). A Gigabit WAN port is helpful. It is useful when your internet plan supports high speeds.
Wireless
| Antennas | 2 x 2 dBi internal |
|---|---|
| 2.4 GHz | yes |
| 5 GHz | no |
| 60 GHz | no |
| Standards | IEEE 802.11a/b/g/n |
| Class | N900 |
| Speed | 450 + 450 Mbps |
| Transmit power | 19 dBm |
| Security | WPA WPA2 WPS |
| Guest network | yes |
A well-positioned antenna can reduce interference and signal weakening. This leads to a more reliable connection. Many IoT devices, smart home devices, and older Wi-Fi devices mainly use the 2.4 GHz band. This is a Wi-Fi 4 router, with slower data transfer speeds. This can result in slower downloads, video buffering, and reduced performance. The top speed, 450 + 450 Mbps, is the highest data rate the router can reach. It's the theoretical limit in perfect conditions.
The introduction of WPA2 (Wi-Fi Protected Access 2) improved upon WEP. It provides stronger security. WPS (Wi-Fi Protected Setup) provides an easy method. It connects devices to a Wi-Fi network.
Connectivity
| USB ports | 1 x USB 2.0 |
|---|---|
| Print server | yes |
| File server | yes |
The USB 2 port has a maximum theoretical data transfer rate of 480 megabits per second (Mbps). By connecting a USB printer to the DIR-855L router, you can make it accessible to all devices on your network. This router has a USB file server. It lets you connect external storage devices to your network. For example, you can connect USB flash drives or hard drives.
Administration
| Default IP | 192.168.0.1 |
|---|---|
| Default username | Admin |
| Default password | [blank] |
Changing the password often is a good security practice. It protects your network and devices from unauthorized access. Changing the default password improves your router's security. It reduces the risk of unauthorized individuals controlling your network.
