acer update
Yesterday a forum member was good enough to get my laptop wireless working -
I fiddled around with some downloads afterwards trying to get my dvd player to work but otherwise I left well enough alone.
This morning - top right hand screen says no network connection - have I upset something somewhere....

Is it not showing any wireless connection available through the networkmanager?

What is the output of
Code:
ifconfig -a
Does
[code]sudo iwlist wlan0 scan/code]
list your wireless network?

In your other thread, you reported a signal strength of 28%. This is not very strong, and could be responsible for your connection problems. If the wireless access-point/router is in another room, the signal may be partially blocked by walls.

I have a similar wireless in my Eee PC, but to be exactly sure run this command.
Code:
lspci -nn | grep Atheros
This is what my output is, note the ID number in the brackets [ ].
Code:
01:00.0 Ethernet controller [0200]: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter [168c:001c] (rev 01)
Then, post the output of this command. It will give more detailed connection information. You can remove sensitive info, like the SSID name.
Code:
iwconfig

I mistyped.
[code]sudo iwlist wlan0 scan/code] should be
Code:
sudo iwlist wlan0 scan
Forgot the bracket.

The ultimate point is, are you seeing any wireless networks, either via network manager, or this alternative method?

Are you using wireless encryption and do you know what kind, WEP or WPA/WPA2?

Thank you for the info.

Reed9 had a typo in that command, he meant this:
Code:
iwlist wlan0 scan
On my system, it seemed to use a variable connection rate. I forced it to use the maximum rate, and it seems to have stayed that way permanently. Try it, and see if you connection improves any.
Code:
iwconfig wlan0 rate 54M

wlan0 No scan results

iwconfig wlan0 rate 54M
Error for wireless request "Set Bit Rate" (8B20) :
SET failed on device wlan0 ; Operation not permitted.

Between typing in code I unpluggeed the eth cable to test the wireless - very briefly the netgear word appeared together with the going around in circles thingy - but it did not connect - then returned to no signal
