Windows 7 - -> Using Ethernet AND WiFi at the same time? <-

Asked By Steve JORDI on 01-Jul-08 06:02 AM
Hi,
I'd like to know if there is a way to tell some application to use the
WiFi TCP/IP instead of the Ethernet one.

My PC has both cards and I'd like to have most software use the
default Ethernet TCP/IP connections, but for example, tell Outlook and
my news reader to use the TCP connection of the WiFi card instead.
Without disrupting Ethernet...

I imagine that it should be possible with tunneling or something
similar?

Are they any utilities, drivers or software achieving such a thing?

For now, I "ipconfig release" my Ethernet board to let the
applications switch to the WiFi connection and then "ipconfig renew"
it to switch back to my Ethernet board.

But I'd like both at the same time, concurrently. Possible?

Thanks for any help


Sincerely,
Steve JORDI

It isn't easy, but if you want to try it, modify the routing table. This how
to may help.

the corporation email server and another one goes to the Internet ...

You're just not supposed to run two Nics on the same subnet at the same
time.  Disable or disconnect the one you aren't using.

As a side note it is all Ethernet.  The only thing the wireless does is
replace the cable, that's it.  Running both the wireless and the wired on
the same network at the same time is the same thing as if you ran two cabled
Nics on the same network at the same time (which you aren't supposed to do
either).

Nah, it can Not be done when using Client OS.

OK

thanks to all. I will continue to proceed as I currently do,
and "renewing" it when switching back to cabled network.

Thanks for your help.

You don't have to do that.
It happens automatically for wireless when you "connect" to the SSID
It happens automaticaly for wired when you plug in the cable.

Do not have the wireless connected at the same time the wired is connected.
Unplug the wired when you aren't using it,...turn off the wireless when you
are not using it,...only use one at a time.  It is simple,..no big deal.

As far as Applications using a certain nic,...can't be done.  Applications
have no idea what a nic even is.  The nic in use for a particular piece of
traffic is determined by the OS's Routing Table,...the route chosen is based
on the Destination IP#,....Applications are oblivious to it.

Hi
The simplest way to do so is to drag a link to the Connection ICON to the
Desktop and then Enable Disable the Wire or and the Wireless connection as
needed by right clicking on the Icon.
Frequent plugging and unplugging a network cable ending up with trashing the
physical connection, and results in reduction of Network's traffic speed,
and eventually the plastic brakes.

Well but that is exactly what I want. Both at the same time.
If I unplug the Ethernet cable, then I lose all my network
connections, etc. I'd like to have them both cohabit together, just
being able to tell some specifiy application to use one NIC over the
other one.

Someone told me to use the "route" command... I'll investigate this.

Thanks for your answers.

Sincerely,
Steve JORDI

No,..you can't.  They are both the same network.


Of course it is going to,...then when you enable the other adapter they will
come back again.


Networking fundamentals just simply do not work that way.  Now before
someone else mentions it,..."Nic Teaming" is a way to use two Nics on the
same network,...but this does not apply nor have any bearing and what this
situation is about.

175767 - Expected Behavior of Multiple Adapters on Same Network
http://support.microsoft.com/default.aspx?scid=kb;EN-US;175767


You can't.


There are some Application Server Services that will attach to a specific
Nic (like DNS Services, IIS Sites), but that does not apply to your
situation.
Applications do not know what a Routing Table is.
Application cannot and do not "choose" routes out of a Routing Table.
Both Nics are the same network in the first place,...so the Routing Table
becomes irrelevant.  The purpose of a Routing Table is to determine the
correct TCP/IP-Based Gateway for a particular TCP/IP-Based Destination when
that particular Destination does not exist within the same network as the
Source.
