I work at a garden. We have many activities in the summer. I setup outdoor wireless using Cisco 1310 wireless bridges, one is root bridge and other is non-root bridge. I find if the non-root bridge behind a tree, the signal reduce from excellent to low. I am using Omni directional antenna. If I have Yagi antenna, will that help? Can I add another AP/repeater/bridge behind the non-root bridge? If yes, how to configure them? Or any other suggestion.
The configuration can be found here:
