LAN and Wireless

I connect both LAN and wireless at the same time in my office which allows
connection for both. When a user needs to go for a meeting, he disconnect the
LAN at his desk and at this point of time, he is still connected to the
network through the wireless. But there is a problem, he can no longer open
network drives, send mails, receive mails, etc... It is fine after restarting
the computer, this should not be the case as this will defeat the purpose of
connecting both. Anyone had met with the same situation or someone can
provide any solutions? Thank you so much!

However, it usually is the case, in my experience.

But what *is* the purpose of connecting both?

I never recommend that laptop users connect using both at once.....you'll
run into DNS and WINS problems. Just pick one....if you know you'll be
leaving the office with your laptop, boot up without the Ethernet cable
plugged in. This is especially true if you use AD.

Gateway and DNS on the WLAN interface are the sane like on the LAN interface?

It is for mobility as users might have last minute meetings in the
conference room, so if they were to connect both at the same time, they are
able to move fast without much hassle to the networking aspect of the
computer. The other reason of connecting to the wireless is because, as we
all know wireless are still not very stable, you might get disconnect on and
off.

Can you please shed some light for me here : What kind of DNS and WINS
problems will I face? Both of the network card interface when connected to
the LAN have the same DNS & WINS except for IP Address.

Hi Marek, yes both both gateway and DNS are the same as in the LAN interface.
Same for the WINS too.

They aren't running out to perform emergency brain surgery on orphans,
surely!

Well - ideally not, if you have a good wireless infrastructure. I use
wireless 100% of the time here & don't experience problems like this - it's
pretty rare that I get bumped off.

Dynamic DNS registration & WINS registration - you'll have two entries for
your computer in each. This is only one of several possible problems you can
run into - you might post in an AD or DNS group for more specific info on
that from the gurus.

Hi
Depending on how the office Network is set, it might be that configuration
of the Metrics on the individual computers would help to resolve the
problem.

However if you have an IT department in the business talk to them first.

Hi Jack, thanks for the respond and information. I must say it is a very good
acticle, but this does not solve the problems I am still facing. I tried
several times but only succeeded once. Do you have any other solutions in
mind?
