Wifi ipw2100 & wired eth0 issues

Im using SLACK 10.0. I have configured my wireless ipw2100 NIC on my laptop & plus i have a via rhine Wired NIC.
I connect to my network with Static class B IP's --

My wired NIc is eth0 & the ipw2100 wifi at eth1 & both of them have the IP's Assigned to them. The problem part is -- i cant ping from my wifi eth1 till the time i 'down' my eth0 using "ifconfig eth0 down". as soon as i down eth0 i can ping from my wifi. can u pls tell me what is the basic problem.. cant the two network cards share the same subnet simultaneosly. im using it successfully in windows

2nd Issue:-
I have to use specific MAC addresses that are authenticated to my ISP.. on slack 10 -- for my eth0 i use the line "/sbin/ifconfig eth0 hw ether 00:07:E9:80:EAF" in the "/rc.d/rc.inet1" file & this changes my MAC address & i am successfully authenticated to my ISP & can surf the net. now i followed the same Procedure for the Wifi NIC also --- "/sbin/ifconfig eth1 hw ether 10:E0:8C:5C:A0:97" & when i do #ifconfig i am shown with the Changed MAC Address

eth1 Link encap:Ethernet HWaddr 10:E0:8C:5C:A0:97
inet addr: Bcast: Mask:

which shows that my MAC address has been changed -- but when i try to authenticate to my ISP it says "not allowed from this machine" because its not connecting from an authecticated MAC address.

I cant configure anything at ISP's END, nor i can tell him anything abt to help me-- nor i can change my isp-- so pointless to discuss abt all that. nothing needs to be done with routers etc cos i can change the MAC address successfully in windows & im authenticated right away. only is the prob with Slack

I just want some help if someone can Focus on what is the problem with the MAC Address.
I must tell that im loading the Firmware the legacy way. in the ipw2100 readme i read :-
create a file in /etc/sysconfig/network-scripts/ifcfg-eth1 " to prvode configuration parameters but im not using that method. rather im doing it in the /rc.d/rc.inet1.conf as :-

# Config information for eth1:

& as mentioned above setting the MAC address "/sbin/ifconfig eth1 hw ether 10:E0:8C:5C:A0:97" in the "/rc.d/rc.inet1" file. can that b an issue
