Not really. Like decimal numbers, IP addresses use characters to separate them 
for readability. For example, decimal may have "135,007,032,121". All the IP 
addresses are doing is using a "." instead of a "," and then they're 
cancelling leading zeros between the "."s (because the computer knows that 
the "." separates blocks of 3 numbers).

They may be too close (although it's unlikely), or they may be too far apart. 
It's impossible to say without some more information about your network. The 
subnet mask determines whether 2 IP addresses can "see" each other. For 
example, a subnet mask of 255.255.255.0 requires that the first 3 blocks of 
numbers are the same.

Could you possibly post the results of netstat -r for each situation, and it 
would probably also be helpful if you could post the subnet masks you're 
using, and any default gateways.

Also, could you describe as best you can how your network is set up? Are you 
using a Wifi router, or are you just using a wifi access point?

With the routing issue, your computer needs to know how to send packets to the 
outside world. The routing table is what it uses to decide. Thus, it sounds 
to me like the routing table isn't quite set up right when both interfaces 
are active. Possibly it's routing everything through your wired interface, 
when you were expecting it to send it through the wireless interface.
