My network is having big problems

[AFSTechGuy]

Ok. So currently i am trying to fix the network for a small business. Here is what we have.
-A modem/Router from our ISP
-3 switches
-A wireless router
They are connected like this.
The modem/router connects to the first switch.
The first switch is connected to the to the second switch via crossover cable
And the Second switch is connected to the third via cross over cable.
The internet port in the wireless router is connected to a port on the first switch with a patch cable.
All of the switches have computers on them as well.

Now for the problem. Everything gets internet. So all o fthe computer on the network including wireless get internet. But the computers connected to the wireless router cant use the printers connected to the computers on the switches. All of the computers on the switches seem to talk fine and share printers ok. But anything connected to the wireless cant. I have been investigating and cant figure this out. Please help.

Thank you in advance.

Why are you using crossover cables? Straight cables are normally used in applications like your network

For sure try replacing the cross over cables
Check workgroup name, assuming its a workgroup, are all the same
Check IP addresses are all in the same range, if statically set try set to automatically pick up from your router
ipconfig from command prompt will give you all the info
Especially check the workgroup name because the pc's will automatically pick up the internet gateway from the router regardless of workgroup name but will not communicate or see other machines therefore not print if it is different.
Hope this helps

Crossover cables may be required to patch the special port to chain the 2 routers. Not all switches and routers have this port then you use a regular port to connect, these take a regular cable but the dedicated chaining port takes a crossover.

Besides he said they all get internet both wired and wireless.

Are both in the same subnet?

Other than that it is a Routing table issue. You need to introduce the routers to each other. This is done many ways in different brands but look thru the settings on both for Routing tables etc.

Why 2 Routers at all ? Does the non wireless router have features that the wireless does not? Perhaps a HW Firewall, intelligent or Cache Ram?

did'nt see the two routers earlier, check to see if the IP addresses the wireless router is allocating are the same range as the ISP router.
