Wireless configuration help
Hi everyone. I need serious help to configure my wireless router (TrendNet TEW-692GR).
It's for a business, we have a switch that has 2 VLAN's;
They can't talk to each others. The first one is for our business (our domain), and the second one is for wired public areas and to deploy a public WiFi.
I can't get the router to dispatch the Internet, and I know the router is working fine.
Under the Status, it doesn't get an IP, it says;
Connected Type : DHCP Client
WAN IP Address : 0.0.0.0
Subnet Mask : 0.0.0.0
Default Gateway : 0.0.0.0
Primary DNS : 0.0.0.0
Secondary DNS : 0.0.0.0
I click 'Renew', and it does not get anything.
Under 'Network' tab, I have;
- WAN Settings
I placed 'Connection Type' to DHCP and leaved everything else like it was.
- LAN Settings
I have changed this;
IP Address : 192.168.20.21 (The IP I want the router to reply)
Subnet Mask : 255.255.255.0
DHCP Server : Enable
DHCP Start : 192.168.20.100
DHCP End : 192.168.20.200
Do I have to set the WAN Settings to STATIC instead of DHCP? And if so, what do I write there??
If any of you needs clarifications, ask the question.

What's the rest of your network look like? What's the WAN port plugged into? Are there any other devices that are behind or parallel to that router? Do you plan on that router being the DHCP server or do you have a separate one?

I have a switch that the last 4 ports are on a separate VLAN
- Ports 1 to 20 = VLAN 1 (192.168.10.x) <-- That's our business VLAN, private
- Ports 21 to 24 = VLAN 2 (192.168.20.x) <-- That's 4 ports for public Internet. We keep 3 wired connection, and I reserve one for the wireless router.
I don't want anything physically connected to the router, only wirelessly.
Of course, the router needs to make some DCHP for wireless clients, but the switch does the rest for the wired ones.
When I connect on the wall in a VLAN 2 plug, I get an IP by the switch DCHP (192.168.20.20, DHCP starts at .20). The Gateway is 192.168.20.254
How do I configure my router to be part of my VLAN #2 and access the Internet as if I was wired to VLAN #2 (port 21-24)?
Thanks a lot!

Is it a good idea to configure my WAN with the same IP range as my LAN inside my router?
WAN Interface IP Settings
IP : 192.168.20.21
Subnet : 255.255.255.0
Gateway : 192.168.20.254
IP : 192.168.20.20
Subnet : 255.255.255.0
DHCP start = 192.168.20.100
DHCP end = 192.168.20.200
Will it work??

Ok, I still think there's something missing here, so I'll just try the generic explanation and see where that gets us and we can take it from there.
A router is a device that *routes* traffic between two different networks. A network is defined as a unique IP and subnet (but that's a whole different discussion.) A router can be buried within other devices such as a switch or firewall. If a switch is listed as a "layer 3 switch" or something to that effect it is both a switch and a router rolled into one physical device. In fact, most small office routers (like a linksys router) is actually a switch, router, firewall, DHCP server, wireless access point, and possibly even several other "devices" rolled into one.
That being said, you will need to route between the 192.168.10.x and the 192.168.20.x ranges. Is your switch a layer 3 switch that can do that? Can you set the TrendNet device into WAP-only mode? I'm sorry to kinda cop-out like this, but having the whole discussion could be lengthy to give you the *right* answer.
What about where out towards the internet link? Modem(s)? Other routers? Firewalls? Anything else that could be doing something like I talked about?
Oh, and one other thing, the Gateway is the "Next Hop" address. So I have to ask, what is at this 192.168.10.254?
