Thread: Problems with Intel Wireless WiFi Link 5100 agn, with wifi "n" connection

dear all,

i’m using ubuntu jaunty 64 bits , have problem in laptop (toshiba satellite a500-141 intel corporation wireless wifi link 5100 agn) wifi “n” connection.

when starts laptop network manager shows established connection if ping command 192.168.1.2 (it's router) answer delay until 46 seconds. after firts ping answer time reduce until 2ms. also, disconnections happen regulary (but network manager shows connection established) ping delay until 40 seconds 1 more time.

if connect wifi "b" or cable, works fine , vista wifi “n” connection works fine too.

try install intel driver, after copy driver "cp iwlwifi-5000-2.ucode /lib/firmware" next step? have iwlwifi-5000-1.ucode installed.

lspci command return:
jordi@jordi-laptop:~$ lspci -nn | grep network
14:00.0 network controller [0280]: intel corporation wireless wifi link 5100 [8086:4232]

, ping results:
