Roaming Network With Multiple WAPs?
Sep 27, 2011
Just checking in to ask about setting up a network with multiple WAPs. Right now, I have it set up with two WAPs, and can roam seemlessly between the two. Same security, SSIDs, etc. I have one broadcasting on channel 1, and the other on channel 11.What I wanted to ask is this: in the future, I'd like to add two wireless access to a different network that exists in the same building. So I'd have two more WAPs, broadcasting a different network with a different SSID. I can assign one to channel 6, but the last WAP will not have a non-overlapping channel to use. Is that going to cause interference issues?

I'm trying to figure out if it is possible to configure in one site a wireless setup that goes like this:
One WLC (5508), multiple LAP's in H-REAP mode.
AP's will be splitted in multiple VLAN's belonging to different departments but with the same SSID.Each VLAN will have it's own DHCP scope. All AP's are located in the same site and I need to know if it is possible to roam between AP's that belong to different departments?

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?

I have configured some iPads and iPhones to Connect to an ASA via AnyConnect (ASA 8.4(1), iOS 4.2.1, AnyConnect 2.4.4009).I have configured the devices with the "iPhone Configuration Utility" (iPCU 3.2.0.267).
My question is: How to configure the "Network Roaming" feature of the AnyConnect via the iPCU?I can configure everything else correctly with the iPCU (server, certificate, connect on demand, proxy settings,...) but as mentioned NO network roaming!

The old configuration was a Linksys/Cisco WRT120N plugged into a NETGEAR ProSafe VPN Firewall FV336GV2. I will list the settings below, but the short of it is that the WiFi router was in charge of getting the wireless clients but the Firewall was the one that assigned IP addresses and all that. This setup worked out just fine except that the WiFi router was in the basement and clients could only connect to it while still in the basement. They wanted to be able to connect to the network wirelessly while on the third floor, but couldn't even see the basement router from there. We shipped out an identical router configured beforehand exactly the same way, save for its MAC address and local IP address (those having premonitions, during troubleshooting I try setting different radio channels as well). The client plugged an Ethernet cable from the wall to port #2, and a desktop to port #3.
The desktop has internet access. Wirelessly, however, had issues The client only had a single laptop to test with, an XP SP3 machine. Unfortunately I couldn't pull specs from it as of this post, so I don't know if it connected by G or N. This laptop, which worked fine in the basement, wouldn't connect upstairs (it would sit trying to get an IP address forever) until I had him "forget" the basement network. At this point, he was able to connect to the upstairs router and access the internet. However, he could then no longer use the access point in the basement. I tried the same troubleshooting steps, like having him delete the wireless profiles from his network card and rebooting the router, but he couldn't even see the basement router while down there anymore.
Occasionally, it would show up for a moment, then disappear before he could connect to it. To make sure it was the basement router that was briefly appearing, I renamed the upstairs router to something else; this confirmed that indeed it was the basement router that was doing the "now you see me, now you don't" act. I then tried setting the basement router to Channel 1 while leaving the upstairs one at Channel 6. Still nothing, even though the laptop was about 25 feet away from the basement router and I had him wipe the wireless profile again. Rebooting the computer didn't solve the issue either. After this, I named the upstairs router back to the same as the downstairs one and had him go upstairs to test; he could connect to it right away.
I figure this is either a configuration issue on the laptop or routers (or firewall). Unfortunately, there weren't any other wireless clients to test with, and I'm not sure there will be when I continue troubleshooting on Monday. By the way, I looked for a "bridge mode" option on the WRT120N and couldn't find one; I'm told that the firmware doesn't support it. I don't feel comfortable putting on alternative firmware unless it's literally the only thing that will solve this. The configurations for the networking equipment are listed below.
NETGEAR ProSafe Firewall:
IP Address: 192.168.50.1
Subnet Mask: 255.255.255.0
DHCP Server: Enabled
Starting IP address: 192.168.50.50

I live in a new apartment building which means a lot of concrete. The internet (fiber) enters the house at the beginning where the modem is hooked up to my Linksys WRT320N. From there two cables run through the house:1 to the home office, where two computers are connected through a switch.1 to the living room, where the Xbox, blue-ray player are connected through a switch.I also have a wifi network running from my WRT320N, but as it is at the beginning of the house, there are some black spots in other parts of the house. I tried to fix this with a Netgear repeater, but that keeps disconnecting.
What I want to do know is place a second linksys device in the living room at the end of the already existing cable that will also broadcast a wifi network, but I want this to be exactly the same Wi-Fi network as I already have. What I want to achieve is that I can walk from one end of the house with my iPad, streaming a video, to the other end of the house and that I always stay connected to the internet and that my tabled just picks up the strongest broadcaster, basically the same as with a mobile phone.

Upgraded our WLC 4404 from 6 to 7 so we could upgrade some WAPs to 3500i. After upgrading all 8- 1120 and 1240s connectivity were lost.
We reverted back to OS 6 and all came back to Controller
WLC Software version = 6.0.199.4
WLC Emergnecy Image Version = 7.0.235
[Code].....
Our vendor states this should be a compatible mix and they are also checking as to why it is not working as planned.

I am looking to enable the internal DHCP on my WLC. I have enabled it and it seems to be operating correctly but I think my routing and or settings allowing me to access anything beyond the private network is wrong.
DHCP is handing out correct IP info and DNS info. How do I route the new private network (10.1.9.*) out to our existing 10.1.4.1. (management IP is 10.1.4.253) Can this be done within the WLC ?

I'm working on migrating autonomous WAPs to lightweight mode in a WLC 5508. Some of the older WAPs are being decommissioned at the same time.
One issue I have found is that after replacing an old WAP in autonomous mode with a new WAP (3502); some clients near the coverage of this new LWAPP are now connecting to another WAP in autonomous mode that has not been converted or replaced yet; but that is located quite far away from where these clients are, actually two floors down. Users on these clients have reported wifi dropouts, which is obvious due to the distance where the old WAP is. A workaround that seems to work is removing the wifi profiles in the client machines and recreating them again, which is not a good solution for all of the wifi profiles we have in place. At this point of time we still need to have the older WAPs until they are all replaced.
How can I get clients connecting to a LWAPP that is closer to their location? I'm wondering what causes those clients to look for an existing older WAP rather than connecting to the new LWAPP, which is broadcasting the same SSID closer to where they aree. Bear in mind that the new LWAPP is working fine and has live sessions working just fine.

We have about 20 of the above WAPs in our company network and are quite satisfied with the performance.However occasionally we need to manually reboot the WAPs in order to resolve sporadic connectivity issues that cannot be resolved on the client devices. In order to optimize the performance we would like to automatically restart our WAPs at a certain time (e.g. at night) on a daily or weekly basis.We are currently using WAP4410N-fw-2.0.0.5-K9.

I am looking for a reference document for the type of devices that are supported under 5Ghz. We are using a 5500 WLC and 3600 WAPs. Lot of users cannot connect to network via mobile devices. Is there a reference doc from cisco which i can use to inform them?

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?

How can I allow AND prevent connection to wireless networks based on their BSSID(MAC Address), when their SSID(default/custom name) is the same and changing SSID is absolutely NOT an option? Physicaly moving closer to the Preferred Network Wireless Access Point is also absolutely NOT an option. i.e.
Allow connect/reconnect to:
SSID - Linksys
BSSID - AA-AA-AA-AA-AA-AA
and
Prevent connection to:
SSID - Linksys

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.

We have a customer who has a WAG120N as their broadband wireless router, and we've sold them some new equipment, part of which is another WAG120N as our salesperson didn't realise they had one.They have a section of the building which the current WAG120N will not reach. Reading around this forum, it seems that I can give the second WAG120N a different static IP on the LAN and use it to expand the range of the WLAN.If I've read correctly, I need to make all the wireless stuff exactly the same except to use different wireless channels on each router. But what do I do with the DHCP server on the second WAG? Is it fair to say that the clients won't suddenly jump to a different IP because they won't have a cause to request a new one? I read one comment that suggested the second should be configured for DHCP relay, and another which contradicted this. Presumably I just don't configure the ADSL on the second WAG as that will only connect to the LAN.

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.

After completing an AD upgrade to 2008r2 I've had my fill of roaming profiles. I want to change all users back so that their profile is on their pc. Of course ideally I'd like this to occur with the user affected as little as possible. Most users are still winxp but some win7 machines too.

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.

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.

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.

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.

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.
