Tried changing the channel (theres only 11 on this modem by the way) but it didn't help, none of the devices would connect to the wi-fi at all after the change and reboots. It was as if the devices didn't know the modem existed (this goes for the 3DS' and the test DSi I bought, I still can't connect long enough to see and set up the modem over the 360 -see my last post for those details), tried to see if something in their settings could be changed to see a different channel but I couldn't find anything that looked like it.

As for those links to the programs that I could use to see how many devices are on the connection, I either couldn't figure out how to use them properly, or they just couldn't find my wi-fi connection period -probably because the connection is closed without a device starting it up, which just crashes the modem any way and completely defeats the point.  All either of them really said were "no wireless adapter found", which I assume is because the connection isn't on all the time, and since I don't have a clue how to properly use these programs, because I'm obviously not an expert in these sort of things, I don't know really what good it is telling me to use them at all.

All in all though, if MAC addresess are any indication, and I'm assuming they might not be, the only devices that ever connect to my modem are the ones in my house. I'm guessing however that I'd be told that it doesn't matter and other devices could piggyback onto the signal/channel without connecting to my modem, so I don't know if I've already answered my own question with that or not.

As for changing IP addresses, I had a difficult time following your steps to change the base IP, since I can't connect to the wi-fi without the modem crashing.. Since the issue is getting worse and the modem won't accept ANYTHING at all connected to the wi-fi connection without a crash (a developement that arose AFTER my post the other night, when I started to try these things), let alone while a wired computer is on with a wi-fi device (like I think I've mentioned), I really couldn't do step 1 exactly like you wanted.

I did try changing the base IP just through one of the wired computers with no wi-fi connection on (because I can't figure out how to turn it on without a device doing it for me) but again the devices acted like they had no clue the modem was even there. Actually, in this case the modem stopped the wired computers from connecting to the internet completely (didn't crash, just wouldn't find anything).

All in all, all we can do now is only use the wired connections. Its gotten to the point where we can't connect anything to the wi-fi even for a short time without the modem resetting, and its greatly limiting the use we usually get from the internet. In fact, the wired connection seems to be much faster now that the wi-fi really can't seem to be used at all... So, not really sure what you want to make of that.
