[solved]wireless setup

I just installed archlinux on my new laptop. All settings are complished except the wireless setting.

I have read the related wiki page, and do just as it says step by step:
https://wiki.archlinux.org/index.php/Wireless_Setup

It seem that the wireless system have already worked.
Here is the output of the 'iwconfig' command:

wlan0     IEEE 802.11bgn  ESSID:"hello508old" 
          Mode:Managed  Frequency:2.437 GHz  Access Point: 00:21:27:22:2A:22   
          Bit Rate=54 Mb/s   Tx-Power=20 dBm   
          Retry  long limit:7   RTS thr=2347 B   Fragment thr:off
          Power Management:off
          Link Quality=59/70  Signal level=-51 dBm 
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

I use NetworkManager to set a static ip address of wlan0. But when I try to ping the gateway, something wrong happen:

ping -c 3 10.13.88.1
PING 10.13.88.1 (10.13.88.1) 56(84) bytes of data.
From 10.13.88.64 icmp_seq=1 Destination Host Unreachable
From 10.13.88.64 icmp_seq=2 Destination Host Unreachable
From 10.13.88.64 icmp_seq=3 Destination Host Unreachable

--- 10.13.88.1 ping statistics ---
3 packets transmitted, 0 received, +3 errors, 100% packet loss, time 2007ms
pipe 3

But if I use NetworkManager to setup my wired card (static ip), it works fine. I can ping my gateway...

Sorry for my poor English.

Re: [solved]wireless setup

Maybe it helps if you compare the output of the commands

ip addr 
ip route

for static and wireless. To see if your static entries result in the same routing.

Thank Strike0  very much.
Problem resolved.

The problem is wrong static ip setting. And I just set a static ip for the WAN port of the router, and use DHCP in the LAN. Then it works.
