Just first check that linksys is turned on and is connected with ethernet cable or wirelessly to the network and computer or not. Then type address and try to go to setup page. If still not working then press the reset key for 30 seconds and let the router reboot. If still not working then that means firmware is corrupted or router has some hardware issue.
> make sure you are connected to the Linksys router either through wifi connection or through ethernet cable.
> now we have to check if we are getting the right ip address on the computer or not.
> and for that press win+r simultaneously and then run box will open and in that box we have to type :- "cmd" (without quotes) and then hit enter.
> Now in the command prompt box type :- ipconfig and hit enter
> and check the default gateway and it should be 192.168.1.1
> if you see this address then you can try this address on the web browser and it will work and still if its not working even you are getting the right ip address then in that case you have to reboot your router
and try again
> and if you are not getting the right default gateway then you have to reset your router then try again.
