I'd go no bigger than a /23 You need VLANs for sure

Good knowledge of DHCP and DNS is a must, along with adequate basic networking knowledge. Depends if you want a 'technical' manager or a people manager...

Not sure if resolved already but I don't think STP is the issue here. There are 2 main types of BPDU, ones for sharing switch information and another for notifying the other switches of changes. If you have cisco edge switches with portfast enabled on the edge ports then a TCN shouldn't be generated each time the port goes up or down.

This could be a problem due to having too many drivers in an image, is this a fresh capture image you created?

Oops, completely forgot about DHCP Relay!

Switches don't have IP addresses unless for management purposes. Everything communicated within a VLAN is switched and everything leaving the VLAN is routed out. Just for FYI, ARP is used to get the MAC Address of a device that you want to send data to, ARP basically maps IP Addresses to MAC addresses.

You should really be using VLAN and ACLs to restrict traffic to your CCTV (which should be on it's own / management VLAN)

If you're using a Cisco switch you create and assign an ip address to what's known as a SVI (switched virtual interface), this will handle the routing to and between other VLANs. If this is your main / core switch you will also have a 'routed port' which probably connects to a firewall or edge router and your switch should have a default route to it. We'll use 2 VLANs for our example (10 and 20) On a cisco switch the whole process would be: Enable Configure Terminal Vlan 10 name Data exit Vlan 20 name Management exit Int vlan 10 ip address 10.10.10.254 255.255.255.0 no shut exit Int vlan 20 ip address 10.10.20.254 255.255.255.0 no shut exit ip routing ip route 0.0.0.0 0.0.0.0 10.255.255.2

If I was troubleshooting this for you I'd go down the path of the access points not being able to keep up with the number of associations (capacity issue) although this shouldn't be a problem with these WAPs. Have you got a spare WAP you can put nearby to try and load balance between 2 sets of laptops and see if that improves the issue? When I was working in a school these were the same symptoms we faced before we did a full WIFI upgrade.

Anybody here play Halo MCC?

Good Point, especially if you have a Xbox One and Halo MCC..

Online gaming uses minimal bandwidth by the way so that's not the issue

How much is a 4500X in real money? I've not worked on anything better than a 3750 in terms of switches and I've nearly got a CCNP... Cisco stuff is too expensive for most places

* INTER VLAN Routing Sorry to be pedantic On topic though I would never use a single core switch if I had a choice, I'd either stack them or join another in a VRRP Pair.

xNand L Hopefully a few other 'IT people' can add me

This can most likely be resolved by the "wait for network at startup / login" as mentioned above, this is something I used to take advantage off when I was a Secondary School student many years ago..

This is the same method I use as well when I build a new base image, it works well enough.

Your client computer will need the DNS server address used by your domain - in this case your server's IP Address You can assign this by installing the DHCP role and configuring a scope for your network, you might have to turn off your current DHCP server as it might respond faster

Have DHCP options 66 and 67 been set on your DHCP server?

Yep, DHCP is something like this: iface eth0 inet dhcp

Use a USB to Serial Adapter, I console into Network Switches all the time I use these. I also have 8 wired into my home lab.

If you're using a redirected start menu then make sure the group policy has applied for the user, it's possible the user may be in the wrong OU?

This person's blog gives you a good idea how to set one up on Windows Server http://www.whitneytechnologies.com/?p=491

Do your APs support both AES and TKIP encryption?

I've had the same problem in the past but I just went and used a MAK Key. It will take a while to BIOS update each one, especially if you have a batch of 30
