On the phone you would need to gointo settings > wireless and enable your wireless radio. You should then get a notification that wireless networks are available. Select your's or a public wireless network if you're at a coffee shop, ect. Enter any applicable passwords. For this to work you need to verify your phone has wireless capabilities and that the phone and router support the same 802.11 standard. Current Standards are a,b,g,n and ac

try locating the wireless switch of your new Acer. It might be accidentally turned off thats why no available wireless network found in range

What you need first is to install the wireless driver for your wireless card in your computer. If you don't have one you need to purchase a wireless card.
Then read the following info to decide what type of Internet access you require.

Wireless connections to the Internet can be achieved by several methods and it depends upon the method of delivery by the Internet Service Provider in your location.
The most common is by DSL and cable, the modems that are used with DSL and cable connection can have a built-in wireless router. Your computer will require a wireless card to connect to the modem/wireless router and the range is restricted to approx. 100 ft depending where the wireless router is located within the building.

The laptop's wireless card can be a built-in device or a plug-in device eg a PCMCIA card or a USB device. and these can also connect to a wifi hot spot in locations such as McDonalds. Star Bucks etc.

There is another method that can connect into the Internet that uses a USB wireless device that connects to a G3 network, bacically a type of mobile transmission and the device is locked into a specific Internet Service Provider. This method gives a wider mobile range (even across states) of connecting to the Internet but usually at a higher cost.

Basically you need to see what the Internet Service Providers offer in your location. Beware of the costs of the various plans they offer in broadband speed, their download limits and the penality for exceeding the limits etc.

When you decide which method you choose, you need to consider setting up your wireless network securely to prevent unauthorized access.

Make sure you are plugging the SMC into the WAN port on the Linksys router and not the LAN ports.  Your internet connection (which is your SMC) should always plug into your WAN port on the Linksys.  Any computers that you may need to plug in, like Desktops that are "wired" and not "wireless", should plug into the LAN ports on the Linksys.  If you are not using the WAN port on the Linksys for your SMC modem, then that would explain why you cannot get to the internet on wireless or wired computers.
Here's why you are getting the "low connectivity" message:

Computers don't understand why the Internet is connecting or not connecting...so the "low connectivity" message you keep receiving has nothing to do with your wireless signal strength.   To a computer NIC, "low connectivity" means your network adapter could not find a DHCP server and receive a valid IP address.  When this happens, your network adapter assigns an IP address to your computer in the following range...169.254.0.0, and will display the "low connectivity" message until it is able to receive a valid private IP address from the DHCP server.  You can verify this by going to START | RUN and typing "cmd" (without the quotes), then hit ENTER.  A black box will pop up....then type "ipconfig" (without the quotes) and hit ENTER.  This will show you your IP address, subnet mask, and gateway address, and you can verify that your IP address is in the 169.254.0.0 range.  A valid private IP address is typically in the 192.168.0.0 range, but could also be in the 10.0.0.0 range, or the 172.16.31.0 range.    Also, make sure you have DHCP server enabled on the Linksys router for the LAN.  This will ensure your "wired" and "wireless" computers receive a valid IP address.  
The WAN port on your Linksys router should be configured to "Obtain an IP address automatically using DHCP".

Cheers!

You first need to establish that you have internet available to your router via cable modem, dsl, etc. Unless your modem is also your wireless router. Take your ethernet connection or cable that resembles a large phone cable and plug in your Acer One directly into the router. You should then be able to get internet. If not, you may have a problem with your internet in general and need to contact your Internet Service Provider. Also if possible try another pc, see if it has internet. Lastly try reinstalling wireless diver in device manager.
