problem with dhcpcd on dell precision laptop

Hi
i have a problem with dhcpcd, at first i thought it was only on my wireless wlan0 device, but after trying with cable on eth0 i think it is in my network settings somewhere.

when i try to connect to my wireless network with wpa2-psk networkManager says it is connected, however when i do ping i have no connection. i solved this simply by doing dhcpcd wlan0 as su. however this works until the network is idle for some time and it drops out again, same procedure as stated. i tried fixing this by installing the iwl4965-ucode driver, but this just made my wireless network unable to connect to my wpa encrypted network, i can however still connect to a neighbours unencrypted network.

seeing this i tried with cable through eth0, same problem with dhcp, solved the same way.
ive search a little bit around the forums here and google before posting, but i cant seem to find any solutions as to what to do.

if it helps here is my lspci:
