updating the firmware
use WPA security
don't use anything else.
It will stay secure with the WPA security and you won't lose the connection. It may get a little slow. The more laptops on the network the slower it will run.
I run a small (12 people) mortgage company. There are about 8 people in the office on a regular basis, and 4 others that come and go. We all work off of lap tops. When we set things up we just had the phone company give us a DSL modem, and we run that to a wireless router.
For the most part this works because it is a small office space, and all is well. The problem is this...it seems that the wireless part of the router "drops" connection ever so often. sometimes once a day, sometimes a couple times an hour.
To test the issue, I connected one computer with Ethernet to the router, and worked off of it all day. Not once did it drop the connection.
So the question is, why would this be happening, and what can I do to fix it?
