I'm having trouble with troubleshooting a wireless network at our small office. The network is shown in the accompanying image link ...

The problem is that no one with wireless connection can share or see shares on the file server. The server (Win Server 2003, SE, SP2) also manages DNS and AD and all wired computers are on the domain. The computers connected to the wireless can only see the internet and nothing local.

Here is what I've tried so far with no avail. I reversed what I did in each step before proceeding to the next idea:

I setup FTP on the server and opened practically all ports on the firewall rules on the router and the wireless router.

I was unable to ping the wireless router form the server or vice-versa.

I disabled the DHCP on the wireless router.

I set the IP range of the wireless DHCP within range of IPs for the Router DHCP. Then changed the IP on the wireless router to a reserved IP in that range. Then included all these "wireless" IPs in the router DHCP and added the wireless router's IP as an static route. I don't know if this makes sense but I was trying to bring all IPs within range of the Router.

There maybe something simple here that I'm missing, but I dont know why. Someone told me to put the wireless router before the actual router. Will this work?! any other suggestion would be greatly appreciated... :[

Sorry, here is the image link:

Your diagram didn't come through. It is unclear from your post if you have two different internet accesses.

"..opened practically all ports on the firewall rules on the router and the wireless router."

Your issue is lan traffic and has nothing to do with wan traffic. Router firewall settings have nothing to do with lan traffic only internet [wan] traffic.

If a single lan you need both wired and wireless in the same subnet. For example the gateway for the wired router would be 192.168.0.1 and the wireless router would be 192.168.0.2

It would appear the wireless lan was in a different subnet then the wired lan.

Please tell us if you have two internet connections. This will determine the proper config recommendation.

Great to see the picture.

You need to setup the wireless router as per this diagram

Thanks for the posts.

I have one internet connection as in the picture. The physical connectivity of the main router (R) and wireless router (WR) are the same as the one in the link with the exception of a hub, unless that matters?

I'm unclear as to what gateway you are referring to. Both R and WR have both "Internet IP Address" settings and "LAN TCP/IP Setup". I assume the former is irrelevant regarding R since thats WAN, but it contains some IP addresses that I assume came from the ISP (has a Gateway IP too). Here is what I have the rest set at:

R:

LAN TCP/IP Setup
IP Address 192.168.10.1
IP Subnet Mask 225.225.225.0

WR:

LAN TCP/IP Setup
IP Address 192.168.10.100
IP Subnet Mask 225.225.225.0
RIP NO

Internet IP Address
IP Address 192.168.10.10
IP Subnet Mask 225.225.225.0
Gateway IP Address 192.168.10.1

The way I read your post, I need to change the Gateway IP address on the WR to a subset of the gateway given by the ISP and set on R? is that correct?

Btw, I'm using a MR814v2 wireless router.

I extended the IP range of the main router to include the IP of the wireless router, and disabled DHCP on the wireless router. Then realized that the cable on teh back of the wireless router was connected to WAN, so put that on one of the LAN connections and this fixed the issues.

Thanks a lot wanderer :)
