I, i am now connected to the internet with my wireless router (Belkin f7d1401 v1) but only via cable i can not via wireless. i have also digited 192.168.2.1 but now i dont know going further

I think you have the upper light blinking and lower light solid. Is that right? The upper light blinking means that the connection to your ISP is not working. Try unplugging/replugging the Ethernet cable in the top port (probably yellow and labeled "WAN" or "DSL" or something). Check the other end of that cable. If you have another Ethernet cable, try swapping it out.

If none of that works, call your ISP to check the connection.

Reading the manual Troubleshooting section it looks like your adsl connection is not working. Try unplugging your internet provider's equipment power supply and waiting 10 to 15 seconds. Then plug it back in.If this doesn't work contact your ISP.

if internet is not working.
u need to double check that u have the right username and pw inside the modem.
Ur ISP should be able to help

install the wireless driver into the laptop

Your MT 882 modem most likely has a DHCP Server that will interfere with the ip address of the router. Did you plug the Router directly into the laptop then go to dos prompt and type in ipconfig/renew . Or reboot the laptop !
Then type in 192.168.2.1 into browser
You need to work out the IP address of your 882 modem and then change the dhcp server leases on it to start at 20 like it might be 10.0.0.1 to 1.0.0.254 or it could be 192.168.1.1 to 192.168.1.254 .
if you are planning on using both devices on the network !
Make the Modem DHCP start at 192.168.2.20 to 192.168.2.254 and then make the Belkin router / modem ip address be 192.168.2.2 and the 882 modem 192.168.2.1 if you plan on using the two devices together on the network disable the belkin dchp server.
if you are using just the belkin then the reboot or ipconfig/ renew will be all you need .

try calling belkin
