Well, been going strong since the weekend. Not one single connection issue. I just wanted to point out that I never had the problem of getting kicked off-line wirelessly, but rather not being able to connect to the access point after some time (a day or LESS).
I recommend trying messing with the settings above, one at a time. I know it sounds tedious but, for example, set it to 20 MHz channel width, then start trying each channel and wait for the problem to arise, then try the next channel??
One theory I have is that some channels are getting interference, not necessarily all the time. Intermittent interference = intermittent connectivity. The one problem I have with this is that why can't I re-connect after the line drop? Why the "re-power" of the unit to get it working again? Odd.
One other thing I did is, once everything was connected and working, I reserved the clients by doing this:
Click
http://www.support.dlink.com/emulators/dir615_revC/310NA/login.htm to start the emulator.
No need to type in the security image. Just click on Log In
Click Newtork Settings on Left
Scroll to bottom, to Number of Dynamic DHCP Clients. Here I could see my computer (Called Windows7), my Wii, and PS3 all connected.
Now, for each one, do this:
Click "Reserve" on the far right of the client. This copies all the info to the fields just above, in the "Add DHCP Reservation". Now click "Save". Note: You can change the "Computer Name" field to whatever you want.
Now that everything seems to working for me now, I will save my settings, and start changing them one at a time, to see exactly when the problem comes back. The first thing I will be changing is the "802.11 Mode" option. What will make testing this a little easier is that the Wii can have 3 connection settings, so I can keep the one that works, and create a new one for testing. As well, I can save my router settings, and bring back the working setup at any point.
One last thing is maybe try re-flashing the firmware, especially if it came with the latest firmware. Think of it this way, your computer always works better after it is formatted and a fresh copy of windows is installed.
Any opinoins on any of this from anyone else?
