Why is server not found when using Netgear N300 wireless router?

Do you have an IP on the wireless interface? You can check by running:

ifconfig

eth0 Link encap:Ethernet HWaddr 00:15:f2:0b:83:ac
          inet addr:192.168.1.64 Bcast:192.168.1.255 Mask:255.255.255.0

ok there is no wireless device. Can you give the output of:

sudo lshw -C network; lsusb; lspci; sudo rfkill list; lsb_release

Thanks

 I have the router connected to the outlet but I can't connect the router computer because then I don't get Internet service. Maybe that's why it says no wireless device. *-network

ok and the output of:

sudo rfkill list; cat /etc/lsb-release

Thanks

It gives me this error when I connect the router to the computer. Same error comes out my laptop.
404 Not Found

It also says Auto Ethernet is established when I connect the router but no Internet

ok well the system has an IP. Can you ping 8.8.8.8 ok?

I did ping 8.8.8.8 and a lot of stuff came out like 64 bytes 8.8.8.8: and it's still running

i

Cool, ok run:

gksudo gedit /etc/resolv.conf

delete all text and add these 2 lines:

nameserver 8.8.8.8
nameserver 8.8.4.4

Save the new file, close gedit then try the web. Is it ok?

Tried the web it's okay directly from the modem to computer but the other way still got the same error 404 Not Found
This server does not support the operation requested by your client.

Okay got the router working, also wired network is working, along with laptop.

If you needed the entries in the file you will need further steps. Let me know if it works after a reboot
