Access points will act as dhcp

Hi,
I am using static ip for all the systems.And installed 1131 acees point in automouns mode with the switch.I don't have dhcp server,can access point itself will act as dhcp server.To lease ip addres to client's

Yes i have a router
But i don't want to use.So i have a doubt whether access point will support r not.
Thank for reply..

3502 access point will not connect to 4400 Series WLAN controller

I recently upgraded our controllers to the latest version 7 software, as I read this was one of the requirements to get them to connect. But I am not having any luck getting into a controller. Normally I plug them in to the network, they pop into the controller listed as something like AP5057.a844.xxxx and then I can finish configuring them, but a static IP on them, etc...
This is the first of this model AP I have tried to deploy, so I am wondering what is different with these. or what I might be missing in the default config in the WLAN controllers.
Niether of which are set to "Master" either.
Thanks in advance, Tandrist

Hi,
The 3500 as you mention are supported on code 7.0
To get the access point to join the WLC we have different options.
If the access points will be on the same subnet as the WLC then you just need to get the APs to get a valid IP address from the DHCP server and once they have an IP address they will join the WLC because they are on the same subnet as the WLC.
If the access points are on a different subnet then the WLC you will need to have a DHCP server configured to give the unit an IP address and use option 43 or DNS so that the APs can send the join request to the correct WLC on a different subnet.
Or if not configure the AP via the console port with the static IP address and WLC IP address.
Also make sure that you have the correct country code enable on the WLC, and that the APs you purchased are the ones to work in this country, because if not the AP will not join the WLC.

E2500 as an additional access point will not connect

Hello,
I have AT&T Uverse which provides Internet for my home. The wireless capability of this router is pretty bad, I don't get good/reliable wireless reception upstairs in my office. The solution was to buy a Cisco E2500 and add it as an access point upstairs.
I have the E2500 LAN port connected to the LAN port of my uverse router downstairs. DHCP is turned off on the E2500. I have my office PC wired into the E2500. The home PC works fine, its getting DHCP from the uverse router downstairs and connects and good speeds. The problem comes with my wireless devices trying to connect to the E2500.
I should mention that yesterday when i bought this, all worked fine. This morning when I came into my office none of the wireless devices would connect to the E2500 at all. But as soon as I remove the cable that connects the E2500 to the uverse router downstairs they will connect via wireless but of course not get an IP address since that is disabled. No idea what is going on here.
I have factory reset the E2500 and uverse router several times and am getting no where. Any ideas what could be causing the wireless devices to not connect at all?

I think you are having problems because you didn't give the E2500 an appropriate static IP address outside of your Uverse gateway's DHCP range.
A better option would be to reset the E2500 to factory defaults and then follow these bridge mode intructions:
http://www6.nohold.net/Cisco2/GetArticle.aspx?docid=28cee6a2fb0d4176a2210942d1d5836c_Setting_up_the_...
You should give the E2500 seperate (different names) SSID's and make sure your wireless channels are different on AT&T gateway and E2500. Use 1, 6, or 11
The best option, however, would be to reset the E2500 to factory defaults and use the IP passthrough feature on your AT&T gateway. If you use the IP passthrough feature on the AT&T gateway, you would use internet connection type DHCP on the E2500 and it would be functioning as a NAT router. The IP passthrough feature on you AT&T gateway allows your E2500 to receive a public IP address and you will be able to avoid the AT&T gateway's NAT. So you will just be using the E2500's NAT. You will need to change the MTU to manual and you can ask AT&T what the appropriate mtu is for Uverse.

E4200 v2 - Using as an access point, will USB storage still work?

If I were to take a e4200v2 and use it as an access point (disable DHCP), would the USB port connected to a Hard Drive still function as network storage?

Yes, it will. The only thing you need to do is make sure you still have a Static IP address on the E4200v2.

2702-UX-K9 Access Point will not associate with controller.

Hi,
I recently purchased nine new 2702 APs. Two of them will not associate with the controller. I realized they they had a different part number. They ended with UX-K9 instead of -K9 like the others. It turns out that these are new AP that are universal for any country. They APs find the controller but need some sort of password to pull the config down. I"m not sure what this could be?

Rasika,
I have the same issue on my home 2504 with these 2700 UX, I have tried code 8.0.100.0, 8.0.110.0 (Docs say this is the min version supported), and even 8.0.115.0 (latest available) still no dice. The AP won't register, and gives the error stated above. I am seeing 2 images available for the AP, the AP shipped with the later image but I AP recovery isn't working because it say's unable to find image with XX in the name? I see the TFTP logs, and name the file accordingly no dice, then the unable to find file name -XX pops up too. As you know I am busy during the day this week, but let's jump on a skype and take a look later maybe you have seen something I haven't?
For good measure, also attempted to join a 3650 here at the house IOS-XE 3.6 no dice, going to try 3.7 too tomorrow, It worked for the 3700 UX AP's we had??

Unable to get ip address from DHCP server for Aironet 1130AG Access Point

I have a network in which DHCP server is enabled. I have read the installation guide also there it is mentioned that 1130G Access point will not have any staic ip assigned to it.So it will automatically get the ip from the DHCP server from the network. I have connected that from the network but it is unable to get the ip address from the same. The same thing i have configured in the netgear it is coming fine. I have seen the sonic wall and used the IPSU tool also from checking the ip address from Mac Address but i am not able to get the same. Please provide me some tips to check where i am wrong in configuration because the first web page also not coming because of the ip address.

narendra,
I would suggest that the AP be connected to a laptop or desktop pc that would run a local dhcp server with a small scope setup...plenty of free ones on the web(this pc would obviously not be connected to your currnet network). This way you can watch the dhcp server hand the AP it's address (this can take a few minutes). Once you have the address use it to access the GUI and give the AP a static address (I find it good pratice to give all my autonomous AP's static addresses for ease of troubleshooting)...Hope that helps.

WRT160N v2 as access point inside LAN

I got this router and I need to set it as an Access Point (will not be using the routing functionality) in the far side of our building. Our LAN uses IP addresss in the range 10.*.*.* with subnet 255.0.0.0, so I need to put the access point ino this subnet. The dropdown box only allows me to set some predefined subnet masks, none of which matches ours. So how am I supposed to set this router in our LAN? Please, help!

Set the access point to a unused LAN IP address inside your LAN (not used by any other device nor inside the DHCP server address pool).
Set the subnet mask to 255.255.255.0.
Disable the DHCP server on the WRT.
Connect a LAN port of the WRT to your existing LAN.
The wireless part is bridged into the ethernet LAN. The IP address of the WRT does not play a role here. The wireless works anyway. (Just like you can use the other LAN ports on the WRT to wire devices to your LAN).
The only limitation you have is that you can only access the web interface of the WRT from an IP address inside the incorrectly configured LAN subnet on the WRT. If you have set the WRT to 10.0.11.12/255.255.255.0 then the WRT is only accessible from IP addresses 10.0.11.*. If you computer does not happen to use an IP address inside this IP subnet you must set a static IP address temporarily to access the web interface. But you only need access to the web interface for configuration purposes. After the wireless is configured it works just fine.
Unless, of course you use WPA/WPA2 enterprise mode which requires to contact the RADIUS server. In that case you must use an IP address on the WRT which allows it to send packets directly to the RADIUS server.
Moreover, I would recommend not to use the broadcast IP address of the LAN IP subnet assigned to the WRT for any other purposes. If you set 10.0.11.12/255.255.255.0 I would suggest not to use 10.0.11.255 for any computer inside your LAN. You'll never know what traffic the router may be broadcasting to the LAN and that could become problematic if there is a computer sitting on that broadcast address (which of course is not really a broadcast address inside your LAN).
The other option would be to change the LAN subnet mask and maybe split the LAN into multiple routed networks.

WRT610N - Both laptops lose connection to access point intermittently

I've tried searching the forums a little but don't see my exact issue.
I have a WRT610N and two laptops (one Windows7 connected over N 5ghz and the other XP connecting over A 5ghz). From time to time, but at least twice a day, especially when doing a heavy download or streaming media, the laptop connection to the access point will be dropped. I have to disconnect from the wireless network and reconnect.
I verified that I was running the latest firmware. I never had to upgrade, was shipped with 2.00.00.05. THe 5ghz network uses WPA2 security and I tried switching from AES only to TKIP and AES. I also tried changing the key renewal interval. One laptop has a DHCP reservation and the other is allowed to get whatever IP. 20 or 40 Mhtz channel width is set to auto.
If anyone has any ideas of things to try before I go return the thing I would appreciate it.

Wireless Roaming with more than one access point

Dear All,
I am trying to set up roaming access points around my home. My main router is the Hub 3 and what I am doing is setting the SSID and channel i want on the hub 3 then setting the same SSID on the additional access point (WNR1000v3) and disabling DHCP on the additional access point and setting a static IP and a different channel to the one on the hub 3.
The problem I am getting is that my devices (android smartphone and tablet) will either only connect to one of the access points when I am near it and then when I go to the area that the hub 3 is in it drops the connection.
I want to know why this is happening because at another house where I work I have additional access points broadcasting the same SSID as the home hub 2! which works.
Please could someone tell me why this is happening and what I can do to prevent it.
Many Thanks,
Dominic

Thanks for the reply Keith,
But why does it not allow for Roaming?
There is an internal Ethernet switch which routes the Ethernet frames to a specific device MAC address, via the wireless module, or the LAN ports, but not both.
Once a device MAC address appears on the LAN side, all frames are routed to that interface, until the physical interface is disconnected.
That prevents the same MAC address connecting to the wireless interface.
Universal wireless repeaters do not have that problem, as all connections take place on the wireless interface.

WGB & light weight Access Point

Hello Experts,
Need your suggestion, though I have gone through some documents the solution does not work as per my requirement as below. Still to confirm.
I wants to use LAP in flex connect mode & standalone access Point to act as WGB. However, as my standalone AP is dual band I want to use 5GHZ for backbone & 2.4 GHZ for my wireless users can it be possible?
Or, over the same backbone can I pass multiple VLAN traffics ? as I, have read it as client after configuring the WGB in standalone so, it should not work !!!
Thanks in advance!!
Lenka...

Yes, you can configure the 5Ghz to handle your "backhaul" if you will from WGB to FlexConnect LAP. Just make sure that only 5GHz has the "station-role workgroup-bridge" configured. 2.4GHz radio will keep the station-role root, for your client access.
The second question; multiple VLANs. Customer facing documentation is conflicting, but newer documentation shows this should work.
http://www.cisco.com/c/en/us/support/docs/interfaces-modules/wireless-lan-controller-module/115752-mesh-wgb-00.html
On the WLC, make sure you enable WGB Vlan support
>config wgb vlan enable
On the WGB you will need to make sure you have the SSID setup with
# workgroup-bridge unified-vlan-client
and then make sure you have all your applicable sub-interfaces on radio and Ethernet.

Trying to figure out difference between Access Point & Gateway

Hello All,
I am trying to figure out how to expand my home network and getting confused by the terms. The following is what I have for equipment"
WRT 130N
WRT 54GS
4 hard wired assorted items hard wired to the 130N
Here is what I want to do and not sure if I can do it:
I would like to use the wireless side of the 54GS to connect to the wireless side of the 130N. By [lacing the 54GS on a different floor of our home we will have four more hard wire ports to utilize for addition hardware we want to network.
My questions are as follows:
Is there a way that using the firmware in the 130N & 54GS to do this> The 54GS is V.7 and the 130N is only about six months old so it's the most current firmware. I am completely confused as to what the difference is between a gateway and an access point.
Today was spent reading everything on the net about after market upgrades and in the end I am only more confused.
Can anyone offer me some advise or guidance?
Thanks,
Ted

access point:
A device that allows wireless-equipped computers and other devices to communicate with a wired network. Also used to expand the range of a wireless network.
gateway:
A device that interconnects networks with different, incompatible communications protocols
Analyzing the network environment that you want to create, is it?
1. wrt130N )))))                                    ((((( wrt54gs ))))                              ((((( 4 devices
2. wrt130N )))))                                    ((((( wrt54gs ----------------------------------------- 4 devices
If it is figure 1. it is not possible, neither figure 2. to get it working that way, because wireless routers can only function as a wireless router, wired router and an access point.
What you can do though is :
wrt54gs- at least fw: 7.50.5   ))))))             ((((( wap54g - in repeater mode - ))))))            (((((( pc
wrt54gs- at least fw: 7.50.5   ))))))             ((((( wap54g - access point client mode- wrt130n - dhcp disabled --------------------- 4 devices
Take note though that wrt54gs has not been know to work with wpa54g access access point client mode
Your best bet is to just wire wrt130n to wrt54gs and change the ip address of the latter to i.e. 192.168.5.1.

LAP Access Point - trunk or switchport ?

Hi Folks.
I always thought that an access point (unless configured not to) would tunnel back to the controller, so would be connected to a switchport in the same VLAN as the management interface. However, if you apply smartport, it configures the port as a trunk port.
Which is the correct way to go ?
Many thanks,
NM

Hi, Surendra.
Thanks for the reply, however it doesn't really answer the question. I can set the port to be a trunk port and the access point will get an IP address if there is DHCP on the default VLAN and it will be fine if the access point management port is also on the same VLAN.
Or I can set it to be a switch port in the native VLAN 1, where the curreent management ports are and there is DHCP.
The question is, "If best practice tells us to use a switchport for access points, why does the smartport role make the switch port a trunk port ?"
That's what I want to know, there must be a reason for it.

Downgraded A1240 Access point to IOS that support CLI command

I have a new A1240 and it IOS is working with new command LWAPP and need a control server to manage the access point. It (ios) does not have configure terminal command. I think I can delete the IOS in the flash and load a older version IOS. I went ahead and deleted the IOS and assumed the access point will go to rommon mode and allows me to archive a tar file (older ios) into the access point. However, I only get AP: prompt and stuck here. I can not run copy or archive command. What are recover process. Need your expert guidance. Au Ray Singapore

Hi Au Ray,
Have you tried this method?
Using the MODE button
You can use the MODE button on 1100 and 1200 series access points to reload the access point image file from an active Trivial File Transfer Protocol (TFTP) server on your network or on a PC connected to the access point Ethernet port.
This process resets all configuration settings to factory defaults, including passwords, WEP keys, the access point IP address, and SSIDs.
Follow these steps to reload the access point image file:
Step 1 The PC you intend to use must be configured with a static IP address in the range of 10.0.0.2 to 10.0.0.30.
Step 2 Make sure that the PC contains the access point image file (such as c1100-k9w7-tar.122-13.JA.tar for an 1100 series access point or c1200-k9w7-tar.122-13.JA.tar for a 1200 series access point) in the TFTP server folder and that the TFTP server is activated. For additional information, refer to the "Obtaining the Access Point Image File" and "Obtaining TFTP Server Software" sections.
Step 3 Rename the access point image file in the TFTP server folder to c1100-k9w7-tar.default for an 1100 series access point or c1200-k9w7-tar.default for a 1200 series access point.
Step 4 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.
Step 5 Disconnect power (the power jack for external power or the Ethernet cable for in-line power) from the access point.
Step 6 Press and hold the MODE button while you reconnect power to the access point.
Step 7 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds), and release the MODE button.
Step 8 Wait until the access point reboots as indicated by all LEDs turning green followed by the Status LED blinking green.
Step 9 After the access point reboots, you must reconfigure the access point by using the Web-browser interface or the CLI.
From this doc;

Is Access Point name and cluster name same, if we have only 1 access point ?

if we have only 1 Access Points, will the name of access point be same as the cluster name ? can i create more then 2 cluster on same role ?

Hi sid,
You can not create a role same with your cluster name, it will cause the DNS resource confilect.

Configuring Cisco Access Points 1602i Air-SAP-1602I-Z-K9

Hi everyone,
I am having touble configuring cisco access points 1602i. I have configured them and they are broadcasting SSID and clients are able to connect to them, but the only thing which is troublesome is speed. I have 100Mbps bandwidth speed but at access point I am getting speed between 17 to 25. Can anyone please tell me where I am gone wrong.
I have Juniper Srx210 configured as backbone for providing internet on fiber. Then further I have attached one POE switch (managable). From that switch I have attached 4 access points.
One more thing,two ports of Juniper is configured as Vlans, one for staff and one for students. I have attached this POE switch to Student Vlan, but haven't configured ports of POE switch as trunk. Please tell me do I have to configure ports as trunk on POE Switch. Is this the cause of slow bandwidth over access points.
I am also planning to go for Wlan Controller to manage Access points. When I contact my supplier about it, told me the following:
"You just need to convert the Access points to autonomous mode. Here are some details, there is no additional charge."
https://supportforums.cisco.com/message/3889653
http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lwapnote.html#wp160918
http://www.youtube.com/watch?v=QQ_NuxdRhQ4
https://supportforums.cisco.com/docs/DOC-14960
I looked at the links but couldn't understand properly. Then I searched over the internet and found out that
"a cisco autonomous access point basically runs on its own while a lightweight access point uses a centralized device called a wireless lan controller to get its configuration. autonomous access points are managed individually, while the lightweight access points can be managed centrally. also, the switchport configurations to support both types of access points will differ. "
I didn't understand, why he suggested to go for Wlan controller and to upgrade access points to autonomous mode, when according to above finding, it says that autonomous access points runs individually.
Please advice.
I shall be thankfull

Hello Scott and Leo,
Thanks for all your help.
I have managed to install and configure 4 Access points and Now Access points are giving speed between 25 to 45Mbps. Still not enought but it sloving the purpose. Everyone is enjoying their face book. I will soon get the Cisco Wlan Controller as well. I dont know if there is a way to get more speed from these access points. I am ready to buy more equipments if required.
Anyway, today I need your guys expretise once again. As you know Junipr Srx 210 is configured for fiber internet to provide internet services to school. Now we are changing the building and transfering the line to new building. This time I want to use Cisco router in place of Juniper Srx210. But I need to know what model will support the current configuration for fiber. Would you please tell me what model/series router will be suitable for fiber internet and for implementing other restrictions.
I am attaching a picture of current jiniper Srx 210 for your consideration.
I shall be very thankfull to you
