Applies to:
Deco BE65/BE63/BE11000_V2.0/2.6
Deco BE25_V1.0/V1.6
Phenomenon:
Recently, we received feedback from several users experiencing frequent difficulties connecting to Google services (e.g., Google Calendar, Gmail, YouTube) while using Deco Mesh Systems on the following ISP networks: Starlink, ISOMEDIA, and Fastel.
Upon further troubleshooting, we determined that, in most instances where this phenomenon manifests, the IPv4 WAN subnet mask is configured with a prefix length lower than /16, such as 255.192.0.0 (/10), 255.0.0.0 (/8), or 252.0.0.0 (/6). This configuration is likely contributing to the connectivity issues observed with Google services:
