Find wi-fi on/off switch

try to connect via lan cable.if u get online then look for wifi switch !

can you connect screen I see in right side of your photo to vga output on laptop and use FN + F5 to switch windows output to secondary VGA device. IPad should connect to Wi Fi but not to Laptop.
Is the router wi fi if it is not plug laptop into ethernet port via cat5 ethernet cable . Do you have a DSL modem you need one to hook up DSL and then Ethernet cable to Router. Also DSL filters are needed on Phones or faxes .

You should be able to install applications and drivers using system recovery partition.
Start/programs/acer/recovery

Maybe overheated ethernet chipset.

The hard disk passwords can be removed only by the manufacturer, at great cost - over $500 per disk. Unless you have really critical files that you cannot lose you should just replace the hard disk and reinstall.

I may not understand you on this because the 5420-5687 notebook should have come with a wireless connection.

Does your "Modem" have both wireless and a hard wired LAN " For instance my "Modem" came only with a hard wire LAN" and no wireless transmitter. I needed to buy a "Wireless Router" to tramsit between the "Modem" and then wireless on my ACER 5420-5687.

If the "Modem" had both the hard wired Lan and a Wireless transmitter it should be able to go directly without the "Wireless Router". If that is true you should see the amber flashing light, on the last in the group of 4 below your touchpad. If it is not flashing as I said above, it is either not sending/receiving or likely not turned on. The on/off switch is alternately turned on/off by sliding the switch below the light to the right.

Hope it helps. I tend to get a little too wordy.

McAfee has controls that can lock you out of the internet. Are you trying to connect via wi-fi or ethernet cable? If it is wi-fi, try disabling McAfee, connect to your wi-fi then turn it back on. You'll need to make an exception for that connection. If wired, disable McAfee, make an exception for port 80, 8080, 23.

There is a WLAN switch located at the front panel of your laptop. It looks something like this (( /\ ))... you need to switch it on for Wireless to work mate :-)

801.11 a/b/g WLAN is wireless networking (wifi) and can be used in a wirless hotspot.

802.11bg is the only wireless driver available. There aren't any other kinds of driver for a wireless card. You must be looking in the wrong place. Just do a google with the brand name of your wireless card and you will find the driver.
