Just some thoughts.
1. That's a very narrow address range. Remember that the first and last addresses may be thought of, as the broadcast address for that subnet. So .2 to .5 could leave .3 and .4 as what's usable and assignable.
I'm not going to enter into any debate if that's right or wrong, but offer this in light of my experiences. Expand that to .2 to at least .10
2. Leave the wireless client to DHCP as that is proper. Try this in a command window...
I have an Actiontec DSL modem with a wireless access point on it. I am connected fine with my D-Link wireless card, however, a friend suggested that I change my "ending" IP to a lower value to only allow a certain numer of available IP addreses to access the network. I tried this (192.168.0.2 = beginning IP, 192.168.0.5 = ending IP). My desktop PC had no problem using one of the available IP's, however, when my wireless tries to authenticate, it cannot. I have even tried specifically assigning the IP from the laptop and no dice. Any suggestions? I can access the wireless fine if I change the "ending IP back to what it was originally, "192.168.0.254" i think. Thanks.
Windows XP on both machines.
