The Network hangs because of DI-804HV DHCP misbehaving
My Network uses DHCP Networking whih is hosted by my DI-804HV Router. The Newtork is as big as 100computers. The Network hangs frequently, the computers register "Limited or No connectivity" problems. I assume the DI-804HV DHCP is misbehaving because it tends to work for some time and stops again after some time.
I f you have more than 100 computers you may have switch use the switch as the dhcp server if it is managable or use one of your pcs as DHCP server
if users are not roaming better you can use static ip

Hmm... on your DHCP server, try setting the "default router" IP for each pool to be the VLAN ID on the switch.
scope 172.16.0.0 /24
router 172.16.0.1
scope 10.20.8.0 /22
router 10.20.8.1
I think the DHCP replies aren't going back where they should. I've never done this without a router doing all the DHCP, but it does work and i've done it many times. Your config looks spot on for the switch.
First set up an static IP address on your computer with a range 192.168.3.x, once you connect to the DI go to >> LAN Settings and change there the DI IP to be in your range of 192.168.2.x.
If you use win XP here is a link how to set up a static IP with your computer: http://www.hotcomm.com/FAQ/FAQ_staticIPXP.asp
Can you tell me the setup with your router? It should be Internet->Modem->Router->Computer
If that's setup properly (the wires in the right spots) then go to the gateway IP of the router...it might be something like "192.168.0.100 "so you put that in your internet browser. The default user is "admin" with no password. Make sure to run the "Wizard" while on that page and after that go to the "Status" page and check to see if the WAN connection is connected properly.
Step 1: Log into the web based configuration of the router by typing in the IP address of the router (default: 192.168.0.1) in your web browser. By default the username is admin and there is no password.
Step 2: Click the VPN button on the left column, select the checkbox to Enable the VPN, and then in the box next to Max. number of tunnels, enter the maximum numbers of VPN tunnels that you would like to have connected.
Step 3: In the space provided, enter the Tunnel Name for ID number 1, select IKE, and then click More.
Step 4: In the Local Subnet and Local Netmask fields enter the network identifier for DI-804HV´s LAN and the corresponding subnet mask.
Step 5: In the Remote Subnet and Remote Netmask fields enter the network identifier for the DI-804V´s LAN and the corresponding subnet mask.
Step 6: In the Remote Gateway field enter the WAN IP address of the remote DI-804V and in the Preshared Key field, enter a key which must be exactly the same as the Preshared Key that is configured on the DI-804V.
Step 7: Click Apply and then click on Select IKE Proposal...
Step 8: Enter a name for proposal ID number 1 and select Group 2 from the DH Group drop-down menu.
Step 9: Select 3DES as the Encryption Algorithm and SHA-1 as the Authentication Algorithm.
Step 10: Enter a Lifetime value of 28800 and then select Sec. as the unit for the lifetime value.
Step 11: Select 1 out of the Proposal ID drop-down menu and click Add To, which will add the proposal that was just configured to the IKE Proposal Index. Click Apply and then click Back.
Step 12: Click on Select IPSec Proposal...
Step 13: Enter a name for proposal ID number 1 and select None from the DH Group drop-down menu.
Step 14: Select ESP as the Encapsulation Protocol.
Step 15: Select 3DES as the Encryption Algorithm and MD5 as the Authentication Algorithm.
Step 16: Enter a Lifetime value of 3600 and then select Sec. as the unit for the lifetime value.
Step 17: Select 1 out of the Proposal ID dropdown menu and click Add To, which will add the proposal that was just configured to the IPSec Proposal Index. Click Apply and then click Restart.
Configuring the DI-804V:
Step 1: Access the router?s web configuration by entering the router?s IP address in your web browser. The default IP address is 192.168.0.1. Login using your password. The default username is admin and the password is blank.

Step 2: Click on Basic Setup and then select Device IP Settings on the left.
Step 3: Change the LAN IP address so that it is on a different subnet than the LAN of the DI-804HV (ie 192.168.1.1).
Step 4: Click Next until you reach the Save & Restart screen. Click Save & Restart and then click Basic Setup once the unit has rebooted.
Step 3: Click on VPN Settings.
Step 4: Name your VPN connection and click ADD.
Step 5: In Remote IP Network and Remote IP Netmask fields enter the network identifier and corresponding subnet mask of the DI-804HV´s LAN.
Step 6: In the Remote Gateway IP field enter the WAN IP address of the DI-804HV and make sure that the Network Interface is set to WAN Ethernet.
Step 7: Verify that Secure Association is set to IKE and that Perfect Forward Secure is Disabled.
Step 8: Verify the Encryption Protocol is set to 3DES and enter in your Preshared Key.
The Preshared Key needs to be identical to the one configured on the DI-804HV
Step 9: Leave the Key Life and IKE Life Time values at their default levels and click SAVE.
Step 10: Click Next and then click on Save & Restart
Establishing a connection:
Step 1: Open a command prompt (Start > Run and type CMD) and from a computer on the internal LAN of the DI-804HV, ping the IP address of a computer that is on the internal LAN of the DI-804V, or vice versa.
Step 2: Once you begin to receive replies, the VPN connection has been established.
Step 3: To view the Status of the VPN on the DI-804V, click on Device Status.
Step 4: From the Device Status screen click on VPN Status.
Step 5: When the VPN has been established, the Status will be Active.
Step 1 Power the unit off by unplugging its power adapter.
Step 2 Insert a paper clip in to the reset pinhole. Press and hold the reset button with light pressure.
Step 3 Power the device back on by plugging it in. Continue to hold the reset button.
Step 4 Watch the lights on the front of the router. The M1 & M2 should come on solid. When the M1 & M2 begin to blink slowly, release the reset button.
The unit will reboot itself and should be at factory defaults. If the M1 light is not blinking about once per second, unplug the power on the router and plug it back in.
If the M1 & M2 continue to blink rapidly, you held the reset button for too long. Power the device off and repeat the reset procedure.
The default IP address is 192.168.0.1. The default username for our routers is admin. The password is blank. If your router asks only for a password, use admin (lower-case).
