Does absense of encryption imply that others will be able to get into my computer through wireless router

I just got a wireless router. I am trying to decide if I want to use an encryption key for it, since it will slow down the connectivity. I don't particularly care if my neighbors take advantage of my wireless connection. They anyway have high speed internet of their own. But what I don't want is for others to be able to see files on my computer. Does leaving the wireless router unsecured open the door for them to see files on my computer even if I have a firewall?

Not using encryption is an invitation for problems. As far as any slowdown, if your wireless lan is 54Mbps and your cable or dsl is only 6Mbs, some small bit of slowdown on the wireless side isnt going to make much difference.

Can't connect to wifi


Try turning off all encryption in the wireless router, delete the SSID's wireless profile in your computer, then connect to the SSID with no encryption. Windows should warn you there is no encryption, and it may limit your connection speed to 54Mbps (802.11n requires WPA2/AES encryption).

But if it then connects OK like that, you know the problem is/was an encryption mismatch.

In that case, switch the wireless router back to WPA2-Personal or WPA2-PSK with AES encryption, delete the newly-created wireless profile for your wireless router's SSID in your computer again, and connect to your WiFi with encryption, being careful to enter the WPA2 passphrase (8 to 63 characters) correctly when prompted.

It will allow some computers to connect but not others WHY?


Encryption is probably enabled in the router's wireless settings. The computersthat cannot connect to the router most like has not had their wireless cards configured with the router's encryption settings.

Theencryption key secures your data from unauthorized access. The router's password is a Passphrase or the WEP or WPA orWPA2 encryption key. The Passphrase generates the WEP or WPA or WPA2 encryptionkey and this is in the router's wireless settings. To connect to your wireless router, configure the router'swireless settings ie SSID, plus the WPAor WPA2 encryption key and then configure wireless cards in the laptops and orcomputers with these router's wireless settings. Then the laptops and desktopcomputers can communicate with your wireless router.

My wifi doesn't connect to any routers but it connect to my laptop ad-hoc.Still i am not able to use internet through ad-hoc.I have tried restoring my iphone, reset and erase settings, reset network...


Ad-hoc is a computer to computer connection.
You need to change the wireless configuration to Access Point (Infrastructure) mode with encryption.

Your wireless card in your computer or laptop needs to be configured with the router's wireless settings eg. the SSID and encryption key
The encryption key (network key) is in your wireless router, without this key the wireless router won't allow the computer or laptop to connect to this wireless router.
The WEP, WPA, WPA2 encryption key is in your router's wireless settings. Log into your router and got to the wireless settings, you will need to get the SSID and the encryption key. Then go to your computer or laptop's wireless card and configure it with the router's SSID and encryption key, so it will then connect to the wireless router and the Internet.

Trying to hook up an HP wireless printer to my computer and am being asked for WPA passphrase. Have no idea what that is or where to find it, but can't proceed until I do...


The WPA passphrase is a method of configuring the encryption code in the wireless router.
You can generate the encryption code using words and phrases so you can remember the encryption code.
You can view the encryption code in the wireless router or you can generate a new encryption code. If you generate a new encryption code then all the wireless cards in the computers on your wireless network will need to be changed so the computers can communicate/connect with the wireless router.

How do i password protect my Router???


follow the steps below:

  1. Connect a computer to any one of the four LAN ports of the Belkin wireless router.
  2. Open your web browser and type the router IP address of the router (by default, the address is http://192.168.2.1.) in the address bar and press Enter.
  3. Click Login on the top of the page to login to the router. By default the Password is left blank, click Submit.
  4. Click Security under Wireless menu.
  5. Under Security, you can select 64 bit WEP (or 128 bit WEP) or WPA/WPA2-personal (PSK). Note: make sure that your wireless computers will be able to support WPA encryption since not all wireless cards/adapters will be able to. if you're not sure, WEP is the encryption to use
Configuring WEP Encryption:

  1. 1. Select Key 1 and enter any 10 hexadecimal digits - any combination of 0-9, A-F (26 digits if you selected 128-bit as the encryption strength). You may also enter a pass phrase and have the router generate a key for you.
  2. 2. Apply the settings. Please write down the key – You will need it later to configure your wireless computers with the same key.
Configuring WPA-PSK Encryption:

  1. Select WPA2-PSK as your Authentication
  2. Select AES as the Encryption Technique.
  3. Enter a word or group of characters in the Password (PSK) box. The Pre-Shared Key must be 8 to 63 characters in length.
    Note: The PSK (Pre-Shared Key) is case sensitive ("A" is different than "a")
  4. Click Apply changes to save the settings.
once you have enabled your wireless security, you need to reconnect your wireless computer to the wireless signal using your wireless password/network key.

hope this'll help you and just ask me if you'll have other concern
ciao!
