Wifi Networks

[Jon Vaughan]

Hello all,

I have written a program that is a client / server program running over a
wifi network. When the computer boots windows connects to the network 99% of
the time , but now and again it just doesnt connect and needs to be manually
connected. I was wondering if in .net its possible to re connect to the
network ? my other smaller problem is that the client code is set to run on
start up, a splash screen is initially displayed to wait for the network
connection to establish ( timer is set so every 15 secs it tries to ping the
server ), but even thou the connection is established ( connection
notification is show in the system tray ) the program wont connect. It
takes a cancel program and manually re run it before it connects. Its as if
the program is being started before the network connection and due to this
it cant connect.

If anyone has any ideas on either of the above problems Im having I would be
grateful to know them.

Thanks

Jon

Although i am relatively new with VB, my biggest concern here is why your
WIFI net is dropping. Typically WIFI nets are as stable as wired networks.
Are you sure that you don't have some kind of 2.4ghz interference on the
channel (ie portable phones, walkie-talkies, etc?) If it is just one machine
that you lose connection on, perhaps you should blow the driver and config
utility and reinstall it on a cold boot. I wish that i could be of more
assistance with the VB code, but wifi is what i do best (Wireless Network

Hi,

The network is dropping, just sometimes on boot the network isnt
autoconnecting as its setup to do. Once the network is up and running its
100% stable, I will try the reinstall that you have suggested, but its more
of an intermittant problem which happens on the connection after boot up.

Cheers for your info.

Hi Jon,

Just a thought on your second problem; could you create a launch program
that loads on start-up, checks the network and after it gets a response,
then it launches your main application?

It seems a difficult problem to debug because you won't be able to run in
debug mode but maybe you could put some debug lines in to write to a text
file to tell you where it is stalling.
