I have Dell Vostro 3560 with intel 2230 wifi.
I have problem with connection when i am working on battery, on ac everything is ok.
When i use notebook on battery, ping to my gateway rises to 500-800ms. When i plug in ac power, ping is 1-2 ms. I try load module with 11n_disable=1 or bt_coex_active=N, but that didn't work.
