I need to speak tomorrow the network engineer and I would like to understand his so apologise for the Dummy question:

In the school we have a cab with a 24 port Netgear manageable switch with an admin and curriculum VLAN settings.

Usually, as I over heard, in the morning and around 4.30pm there are a slowdown period on the computers which connect to this switch.

No one could track this back yet. Questions:

• What is the best way to track back this slowdown
• Would it be a temporary solution to physical separate the two network with 2 switches
• If that would work how can I link them together to be able to see the curriculum from the admin side.
• Do I need an extra router then?

Too many questions but I have no clue where to start and the gentleman will be paid by hours... can you see where I am coming from?:)

Could you guide me in the right direction please? Any comment would be appreciated and please send links if you down vote the question:)
