yes
No. You can not attach a router and use a standard Verizon Wireless aircard as a wireless access point. This is why they have MiFi which is essentially a wireless access point.
You buy a wireless router, wire the desktop and router to the modem, and use the laptop by getting a wireless card or usb wireless adapter.
The Linksys Dual-band Wireless A+g Notebook/laptop Router is good.
If the laptop computer has a wireless adapter installed, either internally or externally, and it can communicate over that adapter to the wireless router, it is time to disconnect the Ethernet cable. The computer will only use one network path to the router at a time.
I assume you mean - how can you connecy your ps3 to the internet/network via your laptop If you have a Windows 7 laptop then download this program called "Connectify" It enables your laptop to be used as a wireless router and you can connect devices such as game consoles (ps3, xbox etc.) to it and use internet from your laptop. Heres the website for the free program: http://www.connectify.me/download/index.html
If you wish to use the wireless network card built into your laptop, then yes, you would need a wireless router. Many ISP's provide you with a modem that also acts as a wireless router for your internet service. But if yours doesn't then you would need a wireless router in order to connect without cabling. But if you don't mind running a length of ethernet cable from your modem to your laptop, then you wouldn't need a router.
There is no difference between a laptop or a desktop when setting up a router. You should use an Ethernet cable when setting up your router, and use the wireless only after it's setup.
Yes if you use someone else's WLAN
a wireless modem means it has a wireless router built in. A wireless router means just a wireless router. if your modem is not wireless, you will need just a wireless router

Yes, you can. Just your desktop to the router which have recently got. You will able to use your laptop as well as your desktop.
Some devices (like the Nintendo DS) use wireless connection instead of wired for on-line usage, which means you need a wireless router. A laptop is an another example that often uses a wireless router to get on the internet instead of a wired connection.
