Can you post the model of the Cisco AP?

On the casing,charging base,registration form/card or the original package of the PDT6846 there is a long alpha numerical label or a MAC address.

This is an alternate method of identifying a unit instead of the DHCP or manually entering an IP address.

===

At this point,I can only recommend you to recheck the IP address of the Cisco AP,PDT6846 and any other items on immediate wireless network.

Please list them in the format.

Name of the unit:
IP address:
Subnet:
Default gateway:

Keep a log like this will help you save time troubleshooting down the line,

====
Without the require information,I can only tell you to do simple tests.

1)Ask the Administrator/owner/manger to enter the Cisco AP setup to verify the ip address of the AP unit.

2)Use a pc,mac,linux,or laptop that has the wifi card *(802,11a/b/g or n) to ping the Cisco AP.


I have to make sure the AP is up and running before we start troubleshooting.

Please post all answers on the comment window.


I will following up on it.

How to connect wap4410 with pc to confgure


Try disconnecting your Cisco Wap4410 from all other network devices then restart it - it will look for a DHCP server, and when it doesn't find one will choose the IP: 192.168.1.245 ---
Set the TCP/IP settings on your laptop to:
IP:192.168.1.250 / Subnet Mask: 255.255.255.0 / Default Gateway: 192.168.1.245 and connect your laptop ONLY to the WAP4410 using a cat5 ethernet cable ---- you should then be able to load a web config page using internet explorer and browsing to: http://192.168.1.245
-------- I've paraphrased the following info from the Cisco User Support Forum (User Juunda):
"...If you read the administrator guide it states that the WAP4410N will search for a DHCP server first, if the dhcp request times out then will it default to 192.168.1.245 this is done so with a user friendly plug and play mentality in mind. Best practice would be to give the AP a static IP of your choice and in your subnet/network so the fastest way to configure the AP out of the box is to assign a static IP on your pc/laptop in the 192.168.1.X /24 and directly connect to the WAP4410N and give the WAP a static IP, define your gateway, DNS servers and then implement it into your network..."

Failed to verify router settings


Factory reset your router by holding the reset button for 10 seconds. Then hardline directly to the router and log in. If it is a linksys or cisco router you can log in by typing 192.168.1.1 into the address bar. Most ISP's use dynamic addresses but if you have a static one make sure that the subnet and the gateway are correct and that your static IP is on the network. Exp. if gateway is 192.187.20.1, any legitimate static IP would be 192.187.20.2/254 depending on the IP block that your ISP has. they would be able to tell you the settings. But like I said, most ISP's like Mediacom and Comcast use dynamic addresses. Maybe a bit more datail on your issue could help find a solution.

Can't get an IP address over time.


Ok I have guessed a couple of things. Here goes.
the version of software 12.4 (3g) is very old
I think that you have DHCP configured on the AP

the cisco site lists loads of issues regarding DHCP and memory leaks in numerous guises with not only your IOS version but newer versions too.

the reason why I have homed in on this is that you say that the unit works for about a week then essentially stops until you reboot the AP. (I guess that you do this by power cycling not by issuing the reload command) in the short term you have fixed the problem.

I would suggest that you upgrade the IOS to something newer. the current version listed is 12.4(22)T if it's of any help.

lastly as you know when the system actually goes wrong. You are able to issue the reload command with additional settings so it could reload @ X date and time if NTP is configured or you can specify a time duration in minutes if preferred.

I can't think of anything else I afraid.

Dynamic IP address


Dynamic ipaddress - is temporary, the ip changes when you disconnect for example.

Normal, or static ip - It's the same address from day to day.

Just a bit of explanation. E0 interface is for inside network (LAN interface). E1 is for outside (ISP or WAN physical interface). Dialer1 is for PPPoE (the "actual"/logical WAN interface). The 1.0.0.13 is ISP provided static IP address for the use of the server. This configuration example is for running FTP server, which uses the standard TCP port 20 and 21.

The LAN uses 10.10.10.0 network with 255.255.255.0 subnet for both servers and workstations. All servers within the LAN use static IP address. The router is configured as DHCP server to give out IP info (IP addresses, subnet mask, DNS) to workstations that are configured as DHCP client.

Basically I suggest that you deploy NAT (Network Address Translation) and PAT (Port Address Translation) to setup your own servers behind Cisco router. The NAT is used to translate the ISP's given static IP address to your local IP address. The PAT is used to translate TCP ports (the port 20 and 21) between the two IP addresses.

When using NAT/PAT, keep in mind that the Internet-accessible servers are seen from the Internet as their NAT/PAT-ed IP address (the Public IP address) and not the local IP address (not the Private IP address). This understanding is very important when you or someone need to test connectivity to the server and/or when you need to create filter (access list or ACL for short) to allow only certain incoming traffic from the Internet and block others.

Side Note:
For more info on NAT/PAT concept, check out the following FAQ
»Cisco Forum FAQ »NAT and PAT; Introduction and Implementations

Instruments used in this illustration are pretty much standard for running your own servers. Please note that IP addresses, username, and password are changed. However, you could always modify the configuration to suit your situation.

This sample configuration assumes that you have a block of IP from ISP. There is a dedicated Public IP address for the router WAN interface (the Dialer1 interface) and another dedicated Public IP address for the server PAT IP address. If you only have a single Public IP address for both router WAN interface and server PAT IP address, there are several ways to configure the router.

One way is to use the same command as shown in sample configuration.

view plaincopy to clipboardprint?
  1. ip nat source static tcp 10.10.10.2 21 1.1.1.14 21 extendable
ip nat source static tcp 10.10.10.2 21 1.1.1.14 21 extendable
This one configuration way is suitable when you have static IP address from your ISP and you know exactly what the IP address is. In this case you have the 1.1.1.14 single static IP address for both the WAN interface and Public server IP address.

When you are unsure which IP address you receive from the ISP, or when your Public IP address keep changing; then another way to configure the static PAT is following

view plaincopy to clipboardprint?
  1. ip nat source static tcp 10.10.10.2 21 interface Dialer1 21 extendable
ip nat source static tcp 10.10.10.2 21 interface Dialer1 21 extendable
With situation of dynamic IP address, at some point you still need to know the exact Public IP address you receive from your ISP for server connection testing and production time. To find out, you can issue show ip interface brief command on the router. You will then see the associated WAN interface Public IP address.
