MSFT 5.0 and dhcpcd-5.5.6: A Guide for Synology NAS Users
Understanding the New Client Vendor Names
If you have recently noticed unfamiliar device names, such as "MSFT 5.0" or "dhcpcd-5.5.6," appearing on your router's list of connected devices, you may be wondering if these are legitimate devices and what their connection to your Synology NAS might be.
MSFT 5.0
The device type "MSFT 5.0" represents a Windows-based device. Traditionally, the Client Vendor Name for Windows devices was simply "MSFT 5.0." However, recent updates have changed this value for some devices.
If you see "MSFT 5.0" in the list of connected devices on your router, it typically indicates a Windows PC or laptop that is connected to your network.
dhcpcd-5.5.6
The process of assigning IP addresses to devices on a network is handled by a protocol called DHCP (Dynamic Host Configuration Protocol).
- DHCP Discover: The device sends a broadcast message to the network, asking for an IP address.
- DHCP Offer: A DHCP server, such as your router, responds to the device's request, offering an available IP address.
- DHCP Request: The device accepts the offered IP address and sends a request to the DHCP server to confirm its acceptance.
- DHCP Acknowledge: The DHCP server sends an acknowledgment to the device, confirming the assignment of the IP address.
"dhcpcd-5.5.6" is the name of a DHCP client software that is used by some devices to manage their IP addresses.
Connection to Synology NAS
The presence of "MSFT 5.0" or "dhcpcd-5.5.6" on your router does not necessarily indicate a direct connection to your Synology NAS. These devices could be connected to other devices on your network, such as a printer, smart TV, or IoT device.
Troubleshooting
If you are experiencing any network issues, such as slow speeds or dropped connections, you can try the following troubleshooting steps:
- Reboot your Synology NAS and router.
- Check for any firmware updates for your router or NAS.
- Run a network troubleshooting tool, such as Windows Network Diagnostics or PingPlotter, to identify any potential issues.
- If the problem persists, contact your internet service provider or Synology support for further assistance.
