MSFT 5 0 and dhcpcd-5 5 6 on Router: Connection Issues with Synology NAS

Potential Connection Issues

Users experiencing connectivity issues with their Synology NAS may encounter the unfamiliar terms "MSFT 5 0" and "dhcpcd-5 5 6" on their router. These issues can arise when a network connection requires a login page or a splash page, causing Microsoft's detection test to fail.

Device Investigation

To investigate potential connection issues, it is recommended to access the router's admin panel and review the connected devices. This may provide additional information about the cause of the problem.

DHCP and Vendor Class Identifier

In some cases, the presence of "dhcpcd-5 5 6" may indicate issues with Dynamic Host Configuration Protocol (DHCP) and Vendor Class Identifier (VCI). By adjusting the VCI settings or using option matching, the connectivity issues may be resolved.

Suspicious Device Name Change

Additionally, users have reported experiencing an unexplained change in their PC's name to "MSFT 5 0." This may suggest a potential security issue, prompting some to consider rebooting their router as a possible solution.
