Most profile request problems are caused by firewall or proxy server settings. http://community.cambiumnetworks.com/t5/LINKPlanner/How-to-Obtain-Path-Profiles/td-p/38869 covers the basics of configuring LINKPlanner to obtain path profiles and viewsheds, but some users still experience problems due to their network settings.
Proxy Server Authentication Errors
LINKPlanner only supports “HTTP Basic” authentication, so if the proxy requires anything else, LINKPlanner cannot connect. This is most often caused by a setting with Microsoft's proxy server, which by default only supports NTLM authentication. The preferred solution in this instance is to enable Basic authentication on the proxy.
What IP addresses does LINKPlanner connect to?
LINKPlanner requests data from the following locations:
- http://linkplanner.cambiumnetworks.com - To check network connectivity, news, updates and remote patches.
- http://pathprofile.cambiumnetworks.com - For viewshed and profile requests.
The IP addresses are dynamic, and they may vary from region to region.
When a profile request fails, the cross is shown in the bottom-right of the main LINKPlanner panel (Figure 1 - Profile request error).
