I'm not sure if we will be able to help, but we certainly need more information:

1. The connection drop messages from dmesg will be quite helpful.
2. What network management software is the machine running? Does it try to 
remake the connection when it drops? The latter question should be evident in 
the dmesg output.
3. Is that Wireless N 150 router able to handle the 802.11g connection of the 
BCM4311?

Note that wireless will always run into conditions that cause a drop of the 
connection. You may wish to rethink your solution.
