I was given a wifi card by a local refufbisher but said not sure if works or not,fair enuf so I fixed it in the slot under keyboard assume right place?
No antenna tho surely it should have one??
Anyway went to acer site for the model put in what I thought was right 802 11g ect
but no joy.I have a wifi symbol on task bar but its in Red and says ESSID no signal
Also in device man yellow ? says no network controller or pci modem I can get the latter off site but it would not affect wifi.
Went to Intel site wifh pci\ven 8086 4220 and it says there isnt one!! what are the fixes and where are they--- atheros--- Intel--- Realtek which is which??
