DHCP address DHCP server doesn't issue new address to a wireless client. Or sometimes it can assing an IP address but then connection is dropped (in about 5 minutes) and no IP address issued any more. This usually happens in the night. When I try it in the morning (before leaving for work, so I can't test it longer than 10 minutes. But even 10 minutes is longer than those at most 5 min I can have in the night) it seems to work fine. The thing works fine for the wired connections (I have 2 other machines connected to the router). And it used to work okay for wireless client about 6 mo ago.

If the IP address pool has much more resources than needs of clients, the following two reasons may cause address exhaustion:
1. An attacker keeps changing the CHADDR field and sending DHCP Discover packets to exhaust addresses. If so, contact Huawei engineers to deploy DHCP snooping to protect the IP address pool.
2. The DHCP server ping function is enabled on the DHCP server. This function tries to ping the allocated addresses before responding to DHCP Offer packets. If a client responds to any ping packet, the DHCP server considers that there are address conflicts and addresses are exhausted. To solve this problem, two methods are available:
1. Capture packets on the ports connected to the DHCP server. If a client responds to ping packets, prohibit the client.
2. Disable the DHCP server ping function using the undo dhcp server ping packet command.
3. Such as S5700, S6700

Log in on your router manager http://192.168.x.x and enable DHCP.DHCP provides an automated way to distribute and update IP addresses and other configuration information on a network. A DHCP server provides this information to a DHCP client through the exchange of a series of messages, known as the DHCP conversation or the DHCP transaction. If the DHCP server and DHCP clients are located on different sub-nets, a DHCP relay agent is used to facilitate the conversation.

1. Connect to your router (by typing 192.168.0.1 or 192.168.1.1 into the URL bar) and log in. Check your user manual or documentation if you do not know the log-in credientials.
   
2. Router Setup tab Make sure you are in the Setup -> Basic Setup category.
3. DHCP is Disabled Scroll down until you see 'DHCP Server' - if it is disabled, select 'Enable'
4. Enable DHCP If you want, you can change the number that the DHCP IP assigning starts. This is optional, and is totally dependant on personal preference.In this picture, the maximum number of DHCP clients is 3. You may need to increase this number according to how many people will need a dynamic IP address on your network. Once the max is reached, no one else can get an address until one expires!
5. Use the DNS servers provided to you by your ISP, or use the following DNS servers: 205.152.37.254, 205.152.132.235, 205.152.132.23; There are many DNS servers out there. It's best to use your ISP's if possible.
6. Don't forget to save! Scroll down and click 'Save Settings'
7. Open up the network configurations for the computers on your network (Control Panel -> Network Connections -> Local Area Connection or Wireless Connection) and select 'Obtain IP address automatically'

A DHCP Reservation is a permanent IP address assignment. It is a specific IP address within a DHCP scope that is permanently reserved for leased use to a specific DHCP client.
You can configure a DHCP reservation in your DHCP server when you need to reserve a permanent IP address assignment. You can use these reservations for DHCP-enabled devices like print and file servers or other application servers which always have the fixed IP address on a network.
To configure a DHCP reservation, follow the steps provided below:

Step 1:
Access the router's web-based setup page. For instructions, click here.
NOTE: To learn how to access the web-based setup page on a Mac computer, click here.
Step 2:
Click Setup > Basic Setup.

Step 3:
Make sure that the DHCP Server option is Enabled. Click the DHCP Reservation button if you want to assign a fixed local IP address to a MAC address.

Step 4:
When you click on DHCP Reservation, a new web browser window will pop-up. Click the Select checkbox to reserve a client's IP address. Click the Add Clients button afterwards.

Step 5:
If you want to manually assign an IP address, enter the client's host name in the Enter Client Name field. You can do this as well in the IP Address and MAC address fields.
Step 6:
Click the Add button.

Step 7:
A list of DHCP clients and their fixed local IP addresses will be displayed at the bottom of the screen. If you want to remove a client from this list, click the Remove button.

You'll want to configure your router as a dhcp server. Connect the switch to your router's lan port. Connect the remaining devices to a port on the switch. Your wireless access point should have it's dhcp server disabled. You can only have one dhcp server per network. The wireless can get it's address from the router's dhcp and the wireless client devices will get their ip address from the router, as well. If your wireless access point is a router with a wan/broadband port and some switch ports you will want to make sure that you are connecting to your Asus switch via one of the switch ports.
Be sure that your client devices are configured to get their ip address via dhcp and you should be surfing the interweb in no time flat.

if you have problem sir/mam just contact me. Reggie is your best contact solution to your problems.. Thanks

What seems to be the problem of your wireless internet?

Hi
I am try to take a stab at answering your query.

Internet Protocol (IP) Address preceeding with "169" means your PC is not receiving IP Address "generally" from your Boradband Modem or Internet Service Provider (ISP). The PC through Automatic Private Internet Protocol Addressing (APIPA) is assigning itself a temporal IP address.
This conditions means either
1. Dynamic Host Configuration Protocol (DHCP) Client service is not running properly on your PC (Unlikely)
2. There is no connection between your PC and Broadband Device or ISP wired or wirelessly (very likely)
3. DHCP Server Service is not configured or not running on Boardband device (likely) or ISP (unlikely)
4. Some firewall software when improperly configured are known to block all ports and services. This can block TCP Ports 67 and 68 used by DHCP Client/Server communication (quite likely)
Some pointers for more info;
1. Your query suggest your issues are limited to Wireless connection. Can you access Internet through wired connection? If so;
a) What Wired connection is in use? USB or Ethernet?
b) Is wired connection through same Broadband device?
c) What IP is assigned to your PC in wired connection?
d) If wired connection works, is IP assignment static or by DHCP?
e) What Boardband device is in use? In which mode is the device set to? Router/Bridge
2. If you can't connect both wired and wireless, then it is unlikely your PC hardware is at fault. Call your Broadband Provider for further help and configuration. Try entily disabling your firwall software (if installed) and test conection.
3. If you can connect through wired connection and your IP Address does not proceed with "192.168" or "172.16" then your boadband device is likely in a bridge mode. In bridge mode, the DHCP Server Service on your boardband device is disabled. Most ISPs will only assign only one IP address to a user. If an IP address has been assigned to your PC on the wired connection, then the wireless connection will not receive an IP address and therefore your PC will assign itself an IP in the range "169.254"

Usually you will have an IP address starting with 169 if the adapter cannot get an ip address from anywhere, it is an autmoatic IP address.

What operating system (Windows XP or 2000 or Vista) are you using?
