Cisco Wireless :: Wi-Fi Phone 7925 - Packet Dropped When Roaming Between APs?
Jun 25, 2012
recently we have deployed a Two APs in branch office warehouse and I have one wifi phone 7925 used over there. the problem is every time when phone roaming from one AP to another, 2 or 3 packets dropped, following is result of the 'debug client ':

have configured Cisco IPPhone 7925G with EAP-TLS setting. (With manufacture installed and Userinstalled certificate). My issue is while roaming from 1 AccessPoint to another AccessPoint the call getting droped. I need to restart the IPPhone to reauthentiate again. In ACS am agging the authentication time-out error. (I had changed the time out value for EAP-TLS to 20 in WLC as per recommendation.)
If am using static web key there is no issue in roaming.
What is the reommended setting inorder for the EAP-TLS to work properly.

How to get the FCC ID from a 7925 phone. We have one on order for an upcoming VoFi site survey but I wanted to take a look at the maximum output power by channel so I can begin cell/channel planning.

I've been fighting with my E2500 since I got it back in June with lag, dropped connections, etc. It's a bit intermittent but can hang around for hours at a time when it kicks in. Restarts but the issue always comes back. Most noticeable while gaming online or on a VOIP program such as Team Speak. Generally when it happens If I'm monitoring my Team Speak connection the incoming packet loss shoots up between 20-30%, starting to drop out every other word or so. No out going packet loss. The connection drops are random between computers (I have one mac and one pc in the house) where one will be fine and the other wont, or when the whole system will stay connected and drop all transfer. In the case of this last one it's not my ISP's connection as any streaming happening between one computer and an Apple TV device will also cease. I've also swapped back to my old router (an older model linksys) and all problems have stopped. Fully rebooted and reconfigured the router about 3 or 4 times and am on the latest version of firmware (1.0.003). It was much worse on 1.0.002 but still very noticeable on 003. Also no difference with a different wireless adapter. I've tried the chat technical support but all they did was take 45 minutes to tell me how to reboot my router after telling them I already had.

We have some remote H-READ APs at a branch office and a 7921 phone which drops calls/loses audio when roaming between APs.We are just using WPA2 without any 802.1x or CCKM/PKC.
Do we absolutely have to set up a radius server/8021.x/EAP to enable fast roaming?We had 2 AP's autonomous with WPA2 before and roaming didn't seem to be an issue. We now have 4 APs over WLC in the same office and the phone calls are very unstable.

We have a problem when I call bettween two 7925 in same SSID, VLAN voice. They cannot hear each other. The SSID and LAPs are in Flexconnet. From desk phones there are no problem and betwen one deskphone and one wireless phone there no problem too.

I have a customer that have trouble with the update of the position of a client. Even if the clients walks across the whole building, the client will stay at the same place for several minutes. Is there any way to tune the refresh rate? When I push the load button in the map, the clients position will refresh, or it did when I was on the site, now they just test with an application.
The setup:
WiSM 7.0.220
WCS 7.0.220
MSE 7.0.220
They use the API for MSE to get the location information to the external application, and that will show the information on a cisco 7925 IP phone.know a way to increasing the refresh rate?

I have an issue with the 7925 phones. We have a Cisco Call Manager with a couple of access points and a wireless lan controller. But we have at some points some sort of hole in the sound. He doesn't loose it's connection because i don't hear the beep when he's out of range. And according to the phone he still has a connection with the access point. But there is no sound anymore. And if i walk a couple of meters further i got sound again. If i walk back i somehow get in the same hole and loose the sound. Further back in i got sound back.
I know when it comes to WiFi that there can be some sort of blind spot but there isn't. He still has it's connection with the AP. Is there a value regarding de RSSI value that he needs to have to get a normal speech?

I'm currently in the process of the setting up a new wireless network and I want to test out our 7925 phones on it. When I try uploading the certificate to the phone it fails and I find the following error in the trace logs
[code]...
I created this certificate using using Windows Server 2003 and it is 2048 bits. This certificate works fine with my laptop but I'm unable to upload it to the phone. The app load currently on the phone is CP7925-MFG-D.8.LOADS. Are there any specific guidelines out there when creating a certificate for a Cisco 7925 phone?

Using Sha1 for Cisco 7925g and sha256 for data. Two separate CA's, one EnTrust (SHA1) the other Local Wondows CA (SHA256); ISE can only use one at a time to process a particular protocol (ie..EAP-TLS, HTTP, etc...) As a result we have to have a separate PSN just for Wireless and Wired VoIP (which can only hold SHA1 RSA1024).

I have 5 access points (WAP4410N) all connected to a befsr41 8 port/switch router, each AP has it's own SSID. Is it possible to to have one SSID for the entire wireless network so users do not have to change SSID's every time they change locations?

I have more different client networks with one ssid, when a client is in another network gets an ip it still from the old network.
How can I to the wlc change this so he gets one right address. I have a Cisco WLC 5508 and 1262/1252 Access point

I have an issue where I have an AP in one room and another in another.When I walk from one room to the other, I lose signal but manages to see the SSID and join.But, I cannot seem to surf the Internet, I have to manually disconnect and reconnect. Normal wireless routers I reconnect seamlessly without any manual disconnect & reconnect.Currently using cisco 5508 and ap2600.

I´m trying to find the best configuration to improve the roaming in a WLC 7.3I changed the power threshold under the TPC to -67 and in the client roaming I put in custom mode and the minimun RSSI in -78 dBm.but I was wondering if there is a specific configuration to improve the roaming.

Currently have a 5508 in the lab and testing 4 AP's with it. Eventually there will be 18 AP's spread thru out different floor in our building.
So far access is working fine using WPA, 802.1x and the client configured to use windows logon credentials..But it doesn't seem to automatically transfer between access points.

I have 3 Cisco 1242 WAPs that I have deployed at a site that has NO RADIUS/AAA devices. I have given all of them a different channel (1,6,11), but the same SSID and crypto (WPA2-PSK). The issue is when a machine boots up it associates with the closest/strongest AP, but as the device "roams" it does not which to a different AP. It stays associated with the original AP until that signal is gone. Then it quickly associates with the closest AP with no problem.
How do I get the device to associate with the strongest WAP? I have research "fast roaming and WDS" but it seems like you need EAP/LEAP and they do NOT have that at all.

Is it possible to set up a roaming wireless network with wireless access points that are different brands from one another (i.e., D-Link, Cisco, Belkin, etc.)? If so, is there anything special that needs to be configured?

But my laptop often times changes access points as I move about in my office to try to optimize the signal strength, which causes the network to stop working and I had to do "ipconfig -renew" to continue using internet. Problem now is that the IT desk told me that the AP's are overloaded.

I am having some troubles with client roaming on a 5508 controller running firmware 7.3.101.0. As soon as a client roams outside the range of an AP they lose data flow and do not seem to transition to another AP for about 1 minute.This is a small network with 6 x AIRCAP3502E-N-K9 AP's (running in H-REAP mode) on the same floor and clients are a mix of HP notebooks, Mac Books, iMacs, iPads and iPhones. There are several seperate SSID's setup and the problem occurs on all. All are WPA2/AES with either a PSK or 802.1X. Both 2.4GHz and 5GHz radios are enabled with auto power and channel selection.
I have tried changing the roaming settings from default and also playing with the AP power settings to no avail.Is this normal behaviour or is there something I can do to improve the reconnection speed?

Under the section intra controller roaming, WLC 7.0 config guide states that " When the wireless client moves its association from one access point to another, the controller simply updates the client database with the newly associated access point. If necessary, new security context and associations are established as well" URL.Within the phrase "If necessary, new security context and associations are established as well" . What is meant by the new security context ? My understanding is that only an update to the MSCB (with the AP info) is the only requirement as the client is within the same controller and subnet.I just can't think why would the security info needs to be updated.

Actually we have a 4402 controller with 1120 APs both of which are marked as EoL products, we want to jump over the new 2600 APs and 5508 Controller for increase signal coverage but we have the following deals:Last firmware for 4402 controller is 7.0.Firmware needed for 5508 to support 2600 APs is 7.3.Is it possible to configure mobility between 4402 and 5508 even with different firmware branch?

I have two 5508, no anchor, only one SSID with internal web authentication using radius server.Under "Configuring Mobility Groups", Cisco guide says: "If a client roams in web authentication state, the client is considered as a new client on another controller instead of considering it as a mobile client".
I understand that if a client that has already autheticated via web roams between two LAPs that are associated with different WLCs, it has to reathenticate.

I'm looking to deploy a 2504 controller and some AP1142s but would like to provide the client with an alternative, lower initial-cost option in my proposal. I've been researching the AP541N access points but several areas of their implementation seem unclear to me.
Clustering: For the clustering feature is it necessary for the network to have other SBCS components (500 series platforms)? All of their other features are either unapplicable to or already implemented in the network in question; if I have to add another appliance I would rather go the LWAPP route and use a true WLC.
What are the cababilities of clustering? Can I implement some form of wireless resilience by spacing APs closer together than necessary and they will lower transmit dBm and intelligently respond to attempt to cover a new cell where an AP has gone down?
What about roaming? I believe Cisco advertises this as part of a small business voice solution. A client roaming between two access points in the same mobility group (cluster?) on a wireless voip phone should be able to keep connection, as it's analogus to some critical UDP communications that are going to take place on the clients.

I am running a WiFi network built on Cisco 1262 APs and Cisco WLC 5508. My APs broadcast two SSIDs, let call them "WiFi_Pay" and "WiFi_Free". I have a problem: when users migrate from "WiFi_Pay" to "WiFi_Free" (not moving, connecting to the same AP), the connection fails. If they try for second time, it is always successful. My task is to ensure that such migrations run smoothly and be successful from the first attempt.

my hardware set-up : 2x AP 1100 series, 2x AP1131AG (not connected to a Cisco Switch)...all with the latest Cisco iOS
What i want to do is connect these APs and broadcast the same SSID (e.g Aironet and NOT Aironet1,Aironet2..etc). Doing that, a user with a laptop can roam between these APs and won't have to re-enter the password of the SSID every time he changes AP. I would also like the encryption to be with a 128bit password key. From what i have read, i need a local authenticator to do what (Something called Local Radius Server).

I have three Autonomous AP´s in a small office running voice applications, all of them are connected to the same infrastructure switch and they have same configuration, voice Vlan is configure to open authentication. I have two models of AP 1252 and 1262 and I paste Radio configuration below.
First issue: During calls users are facing problems when roaming between AP´s, and eventually calls are dropped.
Second issue: Sometimes one of these AP´s(1252) lose all transmit signal and when return I got authentication error on log.

Setting up a multi floor WLAN using a 6500 WISM Controller. Each floor has an AP group with the floor WAPs assigned. Each floor has a VLAN and the WLC has an interface configured. Each floor has a WLAN configured with the same SSID and the only change is the interface on the WLAN per floor.DHCP is remote on AD servers and each floor as a scope configured.Each floor works fine - we can get connected and get assigned to correct IP address. The issue we had with this setup was moving between floors. When we move up a floor the client loses connection to the inital floor (coverage - as expected). if we disconnect and reconnect it connects to the new floor SSID and gets an IP from DHCP.When looking into this - I then created an interface group and added all the floor interfaces into the group. I then applied the interface group to each floor WLAN and did soem testing - it worked as expected. I could now move between floors.The issue with this is though. When I was testing I already had an IP address assigned from DHCP - before I changed to interface groups. The issue is that the intial DHCP assignment no longer works and we cant connect to the WLAN anymore,

Since two months they work full time with the new Dutch Electronic Patient Dossier.We installed 3 Cisco 5508 controllers, version 7.0.230.0 last year on a HP-switched network on a layer 2 mobility domain.Cisco 1041 AP are
The personnel works woth thin clients url... The one with the double antenna.This client has a Broadcom BCM943228HM4L 802.11 a.b.g.n (2x2) adapter.
On the client they have a connected RDP session to a server with the documents.Now they are walking from one patient to another patient. The problem they experience is a very late roaming. At the beginning of the corridor, the client will associate, but is going to roam at the end of the corridor. We installed 4 AP's on each corridor, so they signal is very well, maybe to well?
I disabled client loadbalancing and band select.The lowest data rates are also disabled. Mandatory begins at 12 Mbps. I can increase this to 18 Mbps.These clients work with PSK, with both methods (WPA-TKIP and WPA2-AES) enabled.We did this because of many old and new clients.
The customer tried to find out the problem with a smartphone, same issue. Very late roaming.I can upgrade the WLC to 7.0.240.0. The only problem I have is the WCS. When upgrading to 7.2 and higher I need to have NCS.
