Here is my issue...I have a LAN in my house setup like this...Cable modem
->Router->switch->Compute r1, computer2
computer1 has a WiFi card on it with a software access point..
I recently set up my wireless pc card on my laptop...and it connects
fine...and I will be surfing the internet and all of a sudden..the links
will not work on the internet...but I can go to the LAN and reach all the
other computers just fine...the connection has a strong signal and still
says it is connected...but the internet (IE) will not work...I then just
repair the wireless connection and it works again...at least for a couple
minutes...The computer with the wifi card (access point) has the windows
firewall running...do you think that is causing my problem...I have also
heard of windows zero configuration...I am not using window to configure
the wireless stuff though..I am using the software that came with the
cards...
I did find that my subnet mask on my LAN is set to 255.255.255.0 and my IP
range is 172.25.25.x
with 172....that is considered a class B network...which should be
255.255.0.0
Would that cause my problems...I don't think so, but I don't know?
I am tired of repairing the connection every couple of minutes...even
though the signal strength is strong and says it is connected..and the LAN
computers still can communicate...I am thinking that it is the windows XP
SP2 firewall that may be causing problems..I am going to disable it tonight
when I get home and see if that helps.
Any help???

Did disabling the Windows XP firewall help any?
It sounds like you might be losing you ip address. Repairing the connection
forces the nic to go out and reach the dhcp server for a new address. When
you lose internet connectiviy, you need to go to a command prompt and run
ipconfig. This will show ip address info for any enabled network devices.
If you show 0.0.0.0 or a 169.x.x.x ip address then you dont have a valid ip
to communicate on your netwrk. If you do have a valid ip, you need to try
to ping your default gateway, which should be the access point computer. If
you cant ping the gateway there is definately a netwrk problem. Let us know
the results of these test before we continue further.
