Hello,I have a latop and a desktop,a router ,a voicegateway and a wireless router.
so I connected the voicegateway to the router and the computer and the wirless router to the the first router or modem.
In this connection I can use the internet on the laptop with the wireless router normally but I cannot use file sharing between the laptop and the computer.
so,any help would be very usefull.

Turn off all firewalls

Enable file & printer sharing on all computers. All computers need to be in the same workgroup for normal network browsing and file sharing.
If you cannot browse to other computers verify that Netbios over TCP\IP is enabled on the network connection.

Open up a command prompt (Start > run > cmd)
Type the following bolded commands and post the results for each affected machine.

ipconfig /all

Note: To post results of commands, alternate click on the top of the command prompt > edit > select all >
alternate click on the top of the command prompt > edit > copy > paste in a message here. If you are on
a computer that can't connect to the internet then paste the contents in a text document and save it to a
portable media like a flash drive, then use an internet capable machine to post the contents.

You have a NAT layer issue with the two routers. Configure the second wireless router as follows and you should have connectivity between the machines.


Connecting two (or more) SOHO broadband routers together.

Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.

Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address, 192.168.0.253 for another router, etc.

Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

Disable the DHCP server in the secondary router.

Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. Leave the WAN port unconnected!

This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).

For reference, here's a link to a Typical example config using a Netgear router

ok,again the connection is as the following:
tp-link 8840 router having 4 ports and it is the main router that have the dsl connection on it.
A motorola vt2442 voice gateway connected to the main router with one cable and the other connects it to the desktop.
A belkin wireless g router connected to the main router with a cable and not connected to the desktop.
Now my question is can I share files between the laptop and the desktop while the wireless router isn't connected to the desktop?
thanks

The VoIP gateway and the Belkin router both have a NAT layer that will block file/print sharing.

Why are you connecting anything to the VoIP gateway, just connect the desktop directly to the TP-Link router. For the Belkin router, configure it as follows, then you'll have file/print sharing capability all over the network.

With your current layout, you will not get file/print sharing working between computers connected to the different boxes.
