All | SM – DNS below |
| Microsoft Vista and Windows 7 will not route a 169.254/16 subnet used as | |
| a NATed SM |
| the default Canopy subnet since these operating systems use 169.254/16 | |
| when DNS Server |
| subnet to talk between local machines. This is not an issue if: | |
| Proxy is enabled |
| - the PC is connected directly to the NATed SM. | |
|
|
|
| - the NAT/routing CPE underneath the NATed SM provides DNS services. |
|
|
|
| However; if a NAT/routing CPE that is not providing DNS services (e.g. |
|
|
|
| some home routers) is placed between the SM and the user’s PC, a |
|
|
|
| Microsoft Vista or Windows 7 machine will not route to the default |
|
|
|
| 169.254/16 SM IP address space to access DNS services. |
|
|
|
| Workaround: Reconfigure the SMs NAT LAN address to a private IP |
|
|
|
| address such as 192.168/16, 172.16/12, or 10/8 or leave DNS Server |
|
|
|
| Proxy disabled. |

Remote | Remote AP Sync |
| Remote AP receives sync from SM by setting SYNC Input to Timing Port. | |
AP | Input (7427) |
| However, if this is incorrectly configured as SYNC input to Power port the | |
|
|
|
| Remote AP will still correctly receive SYNC. |

AP | Disable TCP ACK |
| When optimizing a system for broadcast video, on the AP’s Configuration | |
| prioritizing in |
| => General page configure Prioritized TCP ACK to Disabled. | |
| broadcast video |
| In a system being used for internet access or similar applications | |
| applications |
| prioritizing TCP ACKs improves downloading of FTP files and other | |
| (10263) |
|
| |
|
|
| activities making significant use of TCP ACKs under heavy load. However, | |
|
|
|
| in a system being used for broadcast video or video surveillance, |
|
|
|
| prioritizing TCP ACKs can cause sporadic choppy video in the uplink. |
