Unfortunately I still can't connect in spite of using an external USB wireless connector. I'm on a laptop running XP Pro SP2, but even on a desktop
running 7, I couldn't connect with the same wireless unit.
Prior to the switch to a WPA2 based password, I had no trouble connecting. This has to be some configuration issue.
Apparently you didn't take my earlier question seriously. But I'll offer a possible solution anyway.
Since you were replaced by forcible coup, my thought would be that the youngsters killed your wi-fi connection by "arp poisoning." I won't get into
what that means here, but if that's the case, you can get around it by using a "static" IP-to-MAC arp mapping. I sometimes use this to solve
intermittent or unknown network problems.
The first thing you need to know is that when setting up a router you usually set aside a range of DHCP IP addresses that will be assigned
dynamically. All IP addresses outside that range can be assigned statically. For instance, all the addresses in the range 192.168.1.10 to
192.168.1.200 are DHCP. Anything outside that range can be taken as static addresses. (Sometimes, depending on how you set it up, the DHCP addresses
can also be used statically.) If you happen to know what range has been set to DHCP, pick an IP address outside that for your own use. Otherwise, just
pick one at random and try it.
Now, as you probably know, every network device has a burned-in permanent MAC (media access control) address. Network connections are actually made
through the MAC. By using arp, you can permanently assign an IP address that maps to the MAC address of your network device.
You probably know this, but some people reading this may not: You can find the MAC address of your network device with the command (at the command
Read the resulting screen output. You can't miss it.
Now all you need to do is use arp to map your chosen IP address to your MAC address thusly:
arp -s ipaddr macaddr
As a random example, let's say you want to use the IP address 192.168.1.224 and your MAC address is 00:50:BA:85:85:CA. Use the command:
arp -s 192.168.1.224 00-50-BA-85-85-CA
Keep in mind that this mapping is only good during the current "session" (that is, until you restart your computer). You can, however, put it in a
.bat or .vbs file and run it at startup.
