VLAN needed ?

Hi,

I am using a Vigor 2950 and I tried to control my bandwigth
I put a limitation and gave a priority for my Voip system.
I have ONE ADSL

I discovered, that if somebody is downloading something on our website,
the communication became really poor.

I check the download speed and it's not so fast, that should be able to
manage the Voip at the same time

- I wonder if VLAN would solve the prroblem ?
- Any idea ?


PS: Prefer to ask, because I tried to do it, but if something goes
wrong, impossible to access the device anymore :-( I have a VOIP phone,
I put another VLAN, since this time, I cannot access it's webpage
My Vista desktop is not on the same VLAN
Do you know how I could setup this easily ? ( If needed..)

thanks

No.

The issue is almost certainly that the "download" is saturating the
upstream of your connection. You need to throttle that connection so as
to leave enough bandwidth for your phones.

If the web server is Windows, I don't know what the solution might be.
If it's Linux, tc would fit the bill
