Cannot connect to wirless network during installation.

I tried to install archlinux according to beginner's guide and there is only wifi available to me. I followed instructions given by beginner's guide and when I run

dmesg | grep firmware

, I got the following messages:

 [  7.953350] platform microcode: Direct firmware load failed with error -2
      [  7.989047] platform microcode: Direct firmware load failed with error -2
      [  7.989727] platform microcode: Direct firmware load failed with error -2
      [  7.990090] platform microcode: Direct firmware load failed with error -2
      [  8.075045] iwlwifi 0000:03:00.0: loaded firmware version 39.31.5.1 build 35138 op_mode iwldvm
      [  13.830064] psmouse serio2: trackpoint: IBM TrackPoint firmware: 0x0e, button: 3/3

Does that mean firmware is not installed correctly? And how could I figure it out?
Thanks in advance.

I do not quit understand, would you please explain it more clearly?

Your firmware is loaded and your interface is up: what exactly is the problem?

But I cannot connect to the Internet, after runing "wifi-menu" , choosing SSID I used and entering its passwd, I ping www.google.com, it returns "ping unknow host www.google.com" error. And also why it shows "platform microcode: Direct firmware load failed with error -2" when I run "dmesg | grep firmware"?

I don't think the message "platform microcode: Direct firmware load failed with error -2"
has anything to do with wifi. See this thread. What kernel are you running?

Back to the Wifi. If you can see the access point in wifi-menu, then your network is working. After you try to connect, what does ip addr report?

After entering wifi-menu, I get the following messages:

 Select the network you wish to use
       Flag description:
       * - handmade profile present
       + - automatically generated profile present
       - - no profile present
       ! - active connection present
             TP-LINK_2A5F4A - wpa -38
             TP-LINK_C9     - wpa -61

             happy tom      - wpa -88
      
       < OK >             <Cancel>

I select the first one which is my wifi, and then enter OK, then it shows that:

 Enter a name for the new profile
       [code]wlp3s0-TP-LINK_2A5F4A[/code]
       < OK >        <Cancel>

I entered OK, and get the following messages:

Enter wpa security key for 'TP-LINK_2A5F4A'

I entered the passwd of my wifi, but the following messages are listed:

   CONNECTING FAILED
    Do you want to keep the generated profile('wlp3s0-TP-LINK_2A5F4A')?
      <YES>  <NO>

I am sure the passwd for my wifi is right, so why does it show CONNECTING FAILED?
The kernel version is 3.13.5-1-ARCH
Really appreciate your help.

After the failed connection, are there any clues in the last couple dozen lines of the journal?
I would guess from the AP names that those are all residential routers. You try to connect with the first one and it fails. Do you have access to any of the others?
Can you get to the logs in your router? What clues do the router logs provide?
Is it possible that your router security is set up to not allow machines it does not know to join? (Based on hostname or MAC)
Have you tried disabling IPv6?
Can you turn off encryption in your router in order to test whether you can connect without a password?
What kind of interface do you have. Find out with lspci -nn. There are some very old chipsets that do not support WPA. I had one in my 2000 vintage Toshiba laptop.

Aside from that, it appears that the hardware is working. You card is capable of performing a site survey.
