I have a very simple setup I am trying to get with my 1941W.
Gig0/0 is my WAN port tied to a Comcast Business connection - No issues
Gig0/1 is my internal LAN connection, private IP, dhcp - No issues
Gig0/1 is connected to a 24 port PoE switch via ethernet cable.
The switch connects to a Linksys E4200V2.
What I want to do is get rid of my big PoE switch (which is powering one phone) and my Linksys E4200v2 and use just the 1941W.

OK, I guess I am old school and like it when a router is a router and a switch is a switch.....
Unfortunately there is, from what I can tell, a complete lack of configuration examples. I found many snippets and one entire configuration complete with ppt slides that does not actually work with the 1941W I have (the example shows Interface Gigabit0, while my 1941W has them listed as interface Gigabit0/0)
And I HATE asking for help. I would much rather find a few working examples, read about any command I don't know about, and muddle through getting something to work: It may not be secure or the 'best' way to do it, but they did work.
<mini-rant-off>
So, in my current setup everything is working:
Comcast Cable Gateway--->Static IP<--- Gig0/0 1941W--- 1941W Gig0/1 dhcp pool---PoE switch-------------Linksys E4200v2
|---------------------PoE phone
|------------computer, print server, etc.
And obviously I want the following:
Comcast Cable Gateway--->Static IP<--- Gig0/0 1941W----Gig0/1, Gig0/0/0 to Gig0/0/3--dhcp pool1----------->>>> to wired devices.
1941W---wlan-gig0/0----accesspoint-------------------------------->>>> to wireless devices.
I would prefer to have my wireless and wired links share one DHCP pool, but they do not have to. At this point I would take anything I can get. I do have a working AP configuration from work that connects the AP to devices using WAP, allocating DHCP from a second DHCP pool but can't get the wireless to route outside the box.
I thought it was as simple as assigning a VLAN with a DHCP pool to the 4esg ethernet ports, but that does not quite work. A computer plugged directly into 4esg port gig0/0/0 does correctly obtain a DHCP IP address, but it will not ping anywhere outside the local network. In this case the computer can ping 172.20.40.1, the gig0/1 interface or any other IP on that network, but not anything outside. Interesting enough, if I do an extended ping from 172.20.40.1 I CAN ping outside locations from the inside nat interface of the router.
Do I have to do routing table profiles or something? I am very appreciatve of any help and will gladly give you login to my router....
