I don't see a question above, so I'll just assume that you're asking how to fix your computer so that you can connect to the internet. Is that correct?
If so and since you have reset your computer back to factory settings, you should check that all of your software is updated to the latest versions. This would include your operating system and drivers.
Then, you should check that your computer can connect to the internet via ethernet (RJ-45) cable. You would want to directly connect your laptop using the ethernet cable to your router. If this works, you can move on to trying to connect via Wi-Fi. If this doesn't work, you should check that there are no software/driver issues and/or hardware issues with your computer.
If you are trying to connect via Wi-Fi, again you will want to check that all drivers and software are up to date (so that you are on the latest versions of your operating system and the Wi-Fi care inside your computer has the latest driver so that it can connect to your wireless router). Then you will want to attempt to connect and most likely re-input your Wi-Fi password.
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.
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.
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.
