How can I get each comp. to update wpa tkip automatically?

Wireless security is a good thing but it is a nuisance to have to
release and renew IP addresses whenever the mac address changes. I
find it hard to believe whoever developed this scheme didn't
anticipate this. I have 5 pc's networked to dsl and each other as
well as a wireless printer. Is there a way of setting up the
computers to automatically renew the mac address whenever address
changes or lacking that I suppose a macro could be setup with a link
to the desktop so I wouldn't have to access command in dos and use
ipconfig to release and renew the IP addresses each time?
The printer is the most aggravating since you have to power cycle it
to refresh the mac address whenever it changes. It is an HP deskjet
6840.
Thanks in advance

Hi John,
Your subject and your comment are a little different.
So Im not sure if I understand. Are you in an Ad Hoc network?
Mac addresses are hardwired in and dont change for a particular
adapter, but ad hoc has some pseudo macs (bssid) it throws out there.

MAC addresses should never change... maybe you meant IP addresses... I used
to have all sorts of probs with security, and went to a VPN. There are free
VPN server and client software available on the net.

Maybe I didn't explain it correctly. Using wpa-psk encryption with
tkip and a passphrase. As I understand it the system creates it's own
random security codes based on the passphrase at different times.
This is apparently to make if more difficult for someone to sniff for
the passcodes since they change randomly periodically. What happens
is when they change, not all the computers are powered up all the time
so you have to release and renew the IP address when one of the
computers or wireless printer no longer communicates on the network.
I am using a wireless router with 2 pcs wired to it and the remaining
3 are connected wirelessly 54 G. The HP DJ 6840 is also connected to
all the pc's wirelessly from the router. The idea of having a
wireless printer sounded neat so I paid a little more to get the 6840
which is a wonderful printer but it is a nuisance to have to power
cycle it all the time to re-enable the connection. I know that I
could make the printer IP address static by manually setting it up
outside the range of the dynamic IP address range of the router but I
haven't done that yet. I was just wondering what people in similar
situations do to reduce the nuisance factor.

try making all your IPs static and closing the range to only include thos
PCs and printer. Beefing up your security and taking care of your problem at
the same time.

The actual passphrase never changes (the one you entered). This is the
key
each device must have to associate with the AP. The passprhrase is
used
in creating an encryption key which is rotated, but this should not
affect
connecting to the AP. Not to say it isnt part of the problem but it
doesnt sound correct. Sounds like the routers IP tables or the Aps
association tables
are not clearing and the dhcp server thinks the mac still has an
assigned IP. This is not
the first time I have heard of this happening when devices are power
off and on.
Might check for updated firmware for your router and any drivers for
your failing devices.
My answer in the past to this is to disconnect from the wireless
before a power off
which forces a disassociation or as was mentioned, go for a static IP
network.

Good Luck
