I have an HP MSM410 wireless access point and when I first configured it I couldn't access any other devices on the network, but I could access the internet fine. I figured out that this was because the wireless security mode was restricting traffic to only the default gateway for the router. I do have WPA encryption in place.
For now I have turned off wireless security because I need wireless users to be able to access shares and printers. I have the network protected by WPA encryption. It seems ok to me to turn off the wireless security here but I am interested in here what other professionals have to say.
I want to protect my network best as possible with out inconveniencing the users.
