Confusing wireless problem-works one day then not the next.

Hi, I have a desktop pc and a tablet pc(just think laptop). Anyway I
brought the netgeat MA111 for the pc so I could network the two. At
first it went great, better than great it was perfect, I could surf
the net from bed, transfer files etc. But recently I have had some
serious problems. One day I spent a few hours trying to troubleshoot
them, and then suddenly it started to work and I could ping each other
and ICS was working. I woke up the next day, turned it all on and it
wasn't working.

What make it extremely weird is that both say they are connected with
a strong signal strength. I can see the SSID I make on the pc on the
tablet and try to join it and it seems to work. But I can't even ping
each other. I have PAcketMon running and it detects the ip of the
tablet trying to do stuff, so there is definitely a connection, so I
think the problem is software...
I have tried to set the ips and subnet masks to 192.168.0.1/2 and
255.255.255.0 and then try to ping each other, and I can see in
PacketMon one ip sending a packet to the other but I can't actually
ping each other. If I leave windows to set the ips and subnet, the ips
are 169.254.167.61 169.254.141.238, with a subnet mask of 255.255.0.0(
the uni network has the same subnet so I don't think that is good).
Anyway PacketMon picks up allot of packets, going from an ip to some
other ips, always with a 255 in them, i.e UDP from 169.254.167.61:137
to 169.254.255.255:137 size 78... in the netgear config thing, its
also weird because under site survey it has something with a mac of
02.09.36.A0.86.D2 and it stays there even with the tablet pc off....

I've tried to give you as much information as possible. Hopefully you
can help, Thanks in advance

P.S. firewall off when testing

Bottom line here is that there is some issue with the machines getting a
valid IP from a DHCP Server. Windows assigning a 169.xxx IP to a machine
indicates that. I don't think that assigning a static IP is going to help
either. The machines may be able to talk to each other and that's about
it. This may be due to a mis-configuration somewhere, possibly the NIC's.

Further, I would look at other startup applications like firewall or
antivirus standing in the way of making a connection. One possibility
is your modem. It frequently helps to power cycle the modem and the
router, then bring the computers up when you get only a LAN IP address.
If you continue to have problems, you can try turning off Wireless Zero
Configuration, enter the connection properties in the NIC properties
directly (or use the vendor's configuration utility). When all is well,
then turn on WZC and see if you can then invoke WEP, etc.

My last sentence is not intended to imply that WZC is required for WEP.
You might find that disabling WZC and using a direct setup is more
reliable means of establishing a connection.
