Re: TcpClient Problem

It seems to be more complicated than that. I should have said that I can
ping the host PC from the device successfully using the same IP address as I
am using in the TcpClient I have checked the wireless configuration settings
and they seem to be identical. Under the 'Wireless Information' tab it
reports it as being connected and IP information / subnet mask is correct.
Are there any more settings that I am not aware of?

It sounds like there is no network path from you, on the device, to the
PC. That's probably not a feature of what sort of an adapter is used, but
whether it's actually connected to the right access point/wireless
network. You should compare the wireless configurations on the two
devices...

I have a VB.NET 2003 application that has been running successfully on a
device running CE.NET 4.2. I have recently been supplied with the latest
version of the device, which runs CE.NET 5, and also has a different WiFi
adapter to my original version. The application connects to a desktop PC
using a TcpClient as follows:-

Private client as TcpClient
client = New TcpClient(IPAddress, PORT_NUM)

where IPAddress is 192.169.1.10 (the address of the host PC) and PORT_NUM
is a constant - the number of the port I want to use for the connection
(10000 in this case). The application on the host PC has a listener
object waiting for a connection on the same port number. On the CE 4.2
device it works fine, on the new one I get the error message 'No such
host is known' after a few seconds (on the New TcpClient line above). Is
this likely to be a CE problem or a WiFi adapter problem (or something
else), and what can I do about it? Thanks in advance.
