2 routers same SSID

Hi,
I have 2 WRT54G routers v1.1 and v5.
I want to make wireless network with same SSID.
I've read thru all similar topics and couldn't find why it's not working in my case.
This is domain environment so I already have main router 192.168.1.254
How should i configure these two routers so they both just broadcasting wireless signal?
Thanks

Worked!!!! Fanally. I've changed and tryed all the settings!
The problem was I inserted LAN cable not into port 1thru 4 i put into Internet port!!!

Using two routers for the same SSID

So here's my story. I have a standard Actiontec router in my basment, connected straight to the coax outlet, and connected by LAN Ethernet to a crappy computer nobody uses. It gives off a WPA2 wifi network, let's call it MyNetwork. For the longest time it's been the only router in the house. The coax outlet is on a splitter, splitting the coax outlet into one wire that goes to the Actiontec modem/router and the other to my TV STB. Recently we installed a new coax outlet on the other side of my house and next to it we have a brand new desktop computer that we use often. It has no wifi so and we can't run an ethernet cable throughout the entire house so we got a new Actiontec modem/router from our neighbor who just moved out. It's the exact same Actiontec device.
What we want to do is make it so that both routers give off signal on the same MyNetwork we have to make it a wider reaching signal, and so that I can connect the new desktop computer to the new router with an ethernet cable. I've read so many guides and they're all so confusing and it's such a mess that I almost completely screwed over my network. it seems like the two routers are completely independent of one another, not even aware of the others' existence. The new router is definitely in range of the old one. I've logged into 192.168.1.1 on the new computer and the new router seems to think it IS the old router (or so I think). It showed me all the same devices that have connected to MyNetwork and such, but then again it's always hard to be certain exactly which device is which. After messing around I must have changed some IP address or something, but it seems that 192.168.1.1 doesn't take me to the Verizon login screen, but 192.168.2.1 does. Can I reset those IP addresses?
And of course, can somone please provide a clean, easy to follow course of action as to how to set up two routers on one network?

I suspect it might be a good idea to step back reconsider your ultimate layout. Essentially you now have two (or if the STB is also included, three) coax drops connected to the ONT. It seems that you desire that one of these service the STB, and the other two each service a desktop and a wireless access point. If this is the case, continue reading.
There is no need to consider the original Actiontec router as the primary router, wireless or otherwise. Use the new coax location to connect to the primary Actiontec router (you can use either router). For starters, reset both routers to their factory defaults using the reset switch on the back of each device (for details, do a search).
Once the primary router has been located (or relocated) to the new coax drop, just connect the new desktop there using an Ethernet cable connected to one of the LAN ports on the back of the router. Then set up your primary wireless network based on this router (once again, do a search on these forums for specifics on setting up a basic wireless home network).
Now use the original coax outlet where the first router was located to set up another access point. This access point will provide Ethernet connections plus an additional wireless network (if it's still needed). However you cannot have two wireless devices on a single home network with the same SSID (i.e., network name). Here are details on some methods to do this:

Take a careful look at these suggestions and references to decide if this is what you want. Then report back if there are remaining questions. Good luck.

Is there any way I can control which specific access point I connect (and stay connected) to from amongst a set of access points with the same SSID?

I'm working from a boat in a harbor in which the ISP has deployed numerous access points around the periphery. All the access points share the same SSID and each is configured to use either channel 1, 6 or 11. From my location, there are over a dozen of these access points "visible" (based on the the output of WiFi Scanner) with a range of RSSI and S/N values that vary over time.
The ISP has told me that the quality of my connection should be "perfectly fine" for any access point with an RSSI value better than -75, but I know from experience that my connection quality is miserable (i.e. < 50Kbps download) for almost all of these, including those with RSSI values better than -75. There is at least one exception, however, which gives me on the order of 2Mbps download, which is "great" in this context.
I've tried using a more powerful USB antenna plugged into my MacBook Air (mid 2011), but as far as I can tell, it really doesn't make much difference. Neither does my location within the boat. The overriding factor seems to be which access point I happen to connect up to.
I should point out that the closest access points are about 75 yards away, with many of them being several hundred yards away or more. I'm guessing that even though the signal strength of some of the distant access points is causing them to get "chosen" some times, the results are unacceptable due to the distance.
I'm hoping that I can determine, through experimentation, which access point(s) provide(s) acceptable performance and then configure my Mac to limit my connection to those points through whatever mechanism I need to use (e.g. channel, MAC id, etc.).

Establishing a wireless connection with a client computer is left to the access point for various reasons. One reason that your Mac may not connect to the strongest access point is that it may have reached a limit of the number of clients it can serve, leaving it unable to accept a connection with another. The limit may not be very large.
Suppose that happens, and your Mac establishes a connection with a more distant access point having a weaker signal. Then, suppose a client drops off the network. Doesn't this mean your Mac will switch to the stronger access point? Not necessarily. The throughput delivered to and from your Mac would have to drop below a threshold specified in the AP for it to drop the client, leaving your Mac free to connect with another one. The reason for this is to prevent rapid switching from one AP to another in an area in which two signals are of approximately equal quality. If that were to occur the frequent and repetitive handshaking between the two devices would slow throughput to zero.
In an environment in which several access points are broadcasting the same SSID, Apple provides no insight as to how it determines which access point to choose. This is the reason I suspect this "choice" is a function of the router, or access point. The connection originates with it, not the Mac.
Now, what would solve your dilemma would be to determine a way to control the access point with which your Mac connects, by specifying the access point's unique MAC address for example. In this happy circumstance, you could maintain an editable "whitelist" or "blacklist" of the harbor's access points and be able to choose which among them you prefer.
I do not believe OS X maintains such a record of MAC addresses though, only those of the routers it uses. If I am correct about that, such a solution is unlikely to exist. Don't let that discourage you from searching for one though... I would concentrate on something like "selecting access point by specific MAC address".
I did find this patent application though:
Roaming Network Stations Using A Mac Address Identifier To Select New Access Point
Perhaps it's a start

Same SSID, different passwords

Greetings all,
My work takes me to several schools every week, each with the same SSID (let's call it "faculty"), but each with a different password. I have to enter all the settings manually everytime I walk into a new school, and I'd love for the macbook (and iPhone too) to just remember all the settings for each school. I'm only a teacher so I have no power to change SSIDs or passwords. Is there a way for ML to remember networks by the AP's MAC address (and not just the SSID), or some other method?
Thanks!

I have 3 linksys routers and the iPad has been able to connect to them all. I settled on the Linksys WRT54GL because the others are old and starting to exhibit dropout problems.
My suggestion would be to temporarily shorten your password to one or two digits and see if that helps. Before playing around with the Linksys I would suggest that beforehand you save your config file in case you need to restore the router.
I am on G band only, channel 6. My wireless security is set to WPA Personal, TKIP+AES, and I have a 26 digit WPA shared key. BTW, the 26 digit key is a real pain in the butt, but perhaps provides additional security.
Like nearly everyone else, I am occasionally experiencing short internet disconnects followed by an automatic reconnect. I'm hoping the next iPad upgrade will remedy this.

Cisco ISE 1.2 AD Auth and Internal Auth on Same SSID?

Hello everyone... I'm fairly new to Cisco ISE 1.2 and am looking to try and setup a certain configuration. I'm trying to figure out how to create what amounts to a BYOD dmz'd wireless network that is PEAP based (or tls) but authenticates known users (employees from AD groups) but for users not found in those AD groups uses the internal user database and/or Web Auth? Make sense?
So, I of course can get the Authentication/Authorization policies configured for PEAPTLS and make to AD based on group and provide a VLAN number. No problem... I'm having trouble wrapping my head around how to combine the internal users or web auth users in this mix on the same ssid? I know by reading the ISE statement that the authentication policy if PEAP/TLS, ect is used, then a user not found is rejected and does not continue... Can someone provide an example as to how to accomplish this?
As a side note in 1.2, is there the ability to limit the number of consective logins as in ACS, outside of guess access only? What about in 1.3, which makes me nervous to upgrade in reading the instructions and the 'newness' of it.
Thank you for any help, it's greatly appreciated.

I'd like to confirm if the required changes in the VM server were
made, as there are a few changes in the ISE OS. The changes required are
listed in the release notes, under "VMware Operating System to be
Changed to RHEL 5 (64-bit)". Here's a direct link to the relevant section:
http://www.cisco.com/en/US/docs/security/ise/1.2/release_notes/ise12_rn.html#wp384531
Other causes can be :-
certificate issue on ISE or not enough disk space.

Need to setup AP's with the same SSID

We are looking to purchase two Acess Points for our new building. Currently at our old facility we have two lower end AP's with two different SSID's. Users just manaully switch between the two. I'd like to know how difficult it would be to set things up so users wouldn't have to manually switch as they traveled through the building.
I have been looking at Cisco AP below and was wondering if it had the capability to do this. Is there any other hardware or software required to set something like this up.
Just to clarify I only need two AP's and want things transperent to my users. I want them to be able to walk from area covered by AP1 and to another area covered by AP2 and not loose any connection. Also want this to be automatic so the users do not have to do anything to switch things over.
Any info anyone can provide to help me out would be greatly appreceated. Thanks in advance.
Cisco Aironet 1140 AIR-LAP1141N-A-K9 Wireless Access Point

Note that the part number you gave (AIR-LAP1141N-A-K9) requires a controller to operate. That is because the OS on it is a lightweight image. If you already have the APs, they can be converted to autonomous mode per the instructions at http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lwapnote.html#wp161272. If you haven't yet ordered them, use AIR-AP1141N-A-K9. (Or,use 1142 if you want both the 2.4GHz and 5GHz radios.)
And, yes, if you configure both APs with the same SSID and the same encryption/authentication, clients will be able to connect to both without changing their parameters. Whether or not they roam properly is dependent on how close the APs are to one another and how well the individual clients roam.

Same SSID different MAC address

Ok... This is the best place for me to post this I think...
I am sharing an internet connection and am relatively close to the router (linksys) but because of the materials my building is constructed with I get a **** poor connection. So, there is a closer range extender that I can connect to, the range extender is also a linksys range extender, and I have no problems when I connect to it. The only problem is actually getting connected to it in the first place. My computer will automatically connect to the router rather than the base station. They both have the same SSID, and obviously different MAC addresses. Is there a way to force my computer to only connect to the range extender and ignore the signal from the router?

I have no problems with the range extender itself. It works great. The problem is that my airport card cannot tell the difference between the range extender and the router. Sometimes it will connect to the router, and sometimes to the range extender. I want to force it to connect to a specific MAC address rather than using only the SSID. Is there a way to do this?

How to auto-switch Wi-Fi network for the same SSID?

Hi. In my testing, iPad will auto-switch to antoher same SSID Wi-Fi network when the signal become weak. My question is : What is the condition of auto-swith for iPad?

Question again！

The same SSID used at 3 sites and the same vlan for client IP assignment?

we are deploying 5508 controller and LW APs for wireless IP phone 7925G
Controller is installed at site A and there are APs and wireless phones at site B and C as well.
1. can I use the same SSID for all three sites for wireless phones? or have to use 3 distinct SSIDs?
2. If I can use the same SSID, can I associate one subnet e.g 10.10.131.0/24 for wireless IP phones at 3 sites? (our Cisco UCM is fine with this)
3. if I have use 3 distinct SSIDs, do I have to assign three subnets for IP phones at three sites?
thanks for the help!
Eric

yes.. this is done by HREAP mode.. the below link will help you out!!
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a00807cc3b8.shtml
That is, by default the WLAN will get pushed to all APs.. so if you have a single wlan then this will broadcast the SSID and the remotre site clients will connect to it..
Lemme know if this answered your question!!

Access Connections - Many APs with same SSID (Again)

I have a W520 running Access Connections 6.11 (release December 2013) on Windows 7 Pro 64-bit. Access Connections is still broken in regards to dealing with multiple Access Ponts having the same SSID. It keeps hoping from one access point to another regardless of signal strength of the AP.
The most desirable strategy would be if Access Connections would find and lock on to the best signal strength AP and stay there. However, it doesn't do that. It acts almost randomly. It also keep shifting around. The rate is almost random as well. Sometimes it will stay locked on to an AP for up to 10 minutes, at other times it shifts in as little as 30 seconds.
Other laptops, from other manufacturers like HP, Toshiba, and Apple do NOT exhibit this behavior on our campus. Other Lenovo machines running Access Connections DO exhibit this behavior. The problem is NOT machine specific (ie, not hardware or some weird idiosyncracy of the particular W520 i'm posting about). The problem is Lenovo's Access Connections. The problem is also not a configuration issue with the campus. I have a network at home running Airport Extremes all having the same SSID's and the W520 in question does exactly the same behavior there. Totally different hardware at home vs campus and same behavior. I cannot change the names of the AP as a fix. This is not a capability in the configuration of the AP's. Even if it were, I shouldn't have to do it. Campuses are often configured in this way. Campuses that are large commercial users who I believe are the most lucrative Lenovo customers.
This problem has been going on for literally years with different versions of Access Connections. Here are two threads in the Lenovo Community I found in under 30 seconds. Neither was solved correctly. In other words, Lenovo never fixed the software, and people had to either give up or resort to kludge solutions in their campus configurations.

http://forums.lenovo.com/t5/ThinkVantage-Technologies/Access-Connections-Many-APs-with-same-SSID/m-p...
Lenovo has actually made the problem progressively worse over time instead of fixing it. They have done this by removing the abilty to prioritize AP's by MAC address. Initially, Lenovo allowed you to configure 5 MAC addresses in order. Then, Lenovo removed that capability making it possible to only give a single MAC address as preferred. Finally, in recent iterations, Lenovo removed that capability alltogether. The box is still there in the UI, but it's greyed out. It is very frustrating to have this kind of thing happen. The prioritize capability is fundamentally a kludge, but at least it's something to give a bit of a workaround. Now we don't even have that.
Can a lenovo engineer please look at this issue and give me a timeline for resolution?
BTW, It is still not possible to configure Access Connections with a blank SSID either. I bring this up, because if you're going to fix the Access Connections code for multiple SSID's, you should be aware of the blank SSID problem as well. I imagine they are both in the same part of the Access Connections codebase, at least from a logical standpoint.
Thank you.

I found that there is a setting in the Intel driver (15.9.1.2, released 8/22/2013) for the wireless card (Centrino Advanced-N 6205). The setting adjusts the "roaming aggressiveness". I can only guess this means how often the driver goes out and tries to find a "better" signal and/or bandwidth. The card supports a/b/g so the calculus is complex as to what constitutes "better", and I have no idea how sophisticated the algorithm the driver uses is.
That said, if I set the "aggressiveness" to the most aggressive setting, things work somewhat better. They are still not as a good as other wifi managers bundled with competing products (specifically HP, Toshiba, and Apple so far), but it helps. It does appear that more of the time now, the AP having the best signal appears to be the AP the laptop is attached to.
Lenovo, please consider that forcing your customers to dig around in arcane driver settings and relying on the whims of driver writers and hardware companies to do things correctly and well, is a recipe for failure. Your customers are just going to get annoyed and say to their colleagues, "My old Toshiba seemed to do a better job of WiFi connections. I think next time, I'm going to have IT get me one of those again." And, of course, that colleague will look a lot harder at buying the Toshiba instead of the Lenovo, as well. Wifi connectivity is a very big deal for people who have to move around - and lets not forget, this is a laptop we're talking about, which is explicitly designed to, well, be moved around.
I apologize for being so pedantic, but it often takes such measures to get managers in these companies who control programmer time, to take these issues seriously and allocate the programmer resources to fix these problems.
The problem I am having is still not considered "fixed." I would very much like to hear any other solutions that work better. I would love to hear from Lenovo on the matter. Still waiting.
Thanks.

Same SSID, different vlans

I currently have a 4402 in place, with my main office building working fine.
We are looking at bringing in the wireless at 4 other sites, but we want to use the same SSID.
How would I go about assigning different vlans (networks) to the same SSID.

You can use the "AAA Override" feature on controller. You need to have different dynamic interfaces for different vlans configured on the controller. After sucessful authentication, radius server could pass the dynamic interface information to the controller and controller can put users to different vlans according to the feedback from radius server:

Error fetching network with same SSID, different floors

Dear,
I would like help from you, because I have a problem and I can not detect.
I have six devices installed in the WAP model 4410N on two different floors, and a third on each floor.
Both are with the same SSID, but when I'm walking him on a quest equipment that is in another floor, which causes the machine to drop the connection due to fluctuations and barriers such as walls, doors, windows, elevators, etc. .. .
I wonder how to detect only the AP network of walking even with the same SSID.
VLAN use one at each andaar.
If you have any suggestions thank you.
thank you
Anderson

Hi Anderson,
It sounds like you have 5 access point in standalone and 5 SSID broadcasting but you can't know the difference between which SSID is good depending where you are at.
If you can use any of the AP as a repeater (you may repeat 2 additional ap), when the signal strength of the original connection is low enough, it should fall to the more powerful strength of the repeated SSID.
Additionally, if you'd like to use more than 3 AP in a repeater group, you may want to look in to something like the AP541N. These devices support clustering, up to 10 units.

I want to use the same SSID in two sites (central y remote)

I have several AP in H-REAP mode, one of them is in a remote location anthe other are in the central location. I want to use the same SSID in both locations with differents VLANS.
In the central site, i have 3 WLANS (SSID) whit 3 different VLAN eachother. I put the local swicthing in one SSID that I want to use in the remote site. In the remote location the users can authenticate and everything works fine but in the central location that SSID doesnt work, the user in the central location can not authenticate.
It seems that i can not use the same WLAN (SSID) and use it en both locations checking the local switching.
What can i do?
Many thanks for your help

Look I have 2 two VLANs Interfaces (vlan 252 & Vlan253) created on WLC, beside the management VLAN (ID 254), and there are 8 AP´s installed at the central location, each AP has been connected to my CORE Switch through switch ports mode Access vlan 254.
th aeuthentitcation i have been used is "LOCAL: WPA-WPA2-PSK" in both locations (Central and remote). In the remote sites, tha AP is connected to a cisco switch through switch port mode trunk, and I use VLAN 251. When the local switching feature is activeted on WLC, I can map the VLAN 251 (in te remote site) to the SSID I am using inthe central site and everything works fine but in the central locations the user can associste to he AP but they can not receive IP from the appropiate VLAN.
I don t know what parameter have to change....
Can you helpme?

Centrally Switched and Flex Local Switched WLAN - same SSID

Hi All
I am currently working on a WLAN migration from lightweight to autonomous and would like advice on whether the following scenario is possible.
We've deployed an 8500HA pair at the customer's central HQ with the plan that SSIDs at the central HQ will centrally switch with SSIDs at branch sites locally switching. AP and Flex groups have been configured for the HQ and branch sites. There is a legacy SSID at HQ that will need to break out locally so a flex group is required for HQ.
My original plan was to do this with one WLAN Profile per SSID, configured to locally switch. The HQ AP group will map WLAN to the relevant IP interface with the SSID omitted from the HQ Flex Group so that the SSID will centrally switch. The branch AP groups will be configured with the SSIDs required for branch and Flex groups will be configured to break out the SSIDs into the relevant local VLAN.
My question is, is it possible for an SSID to be configured as locally switched for branches but also centrally switched for HQ, by configuring it in the HQ AP Group but omitting it from the HQ Flex group?
Configured as above a client debug gives the below which seems to suggest that it isn't possible, unless I've configured something incorrectly...
*apfMsConnTask_5: Oct 03 15:48:51.012: c0:18:85:48:c0:5d Central switch is FALSE
My alternative option is to create a second WLAN profile for each SSID with the same SSID name but centrally switched and then apply that accordingly in the AP groups.
If someone can verify the above I'd be very grateful.
Many thanks in advance
Mark

Hi Mark
My question is, is it possible for an SSID to be configured as locally switched for branches but also centrally switched for HQ, by configuring it in the HQ AP Group but omitting it from the HQ Flex group?
When you configure an SSID for local switching, it is only applicable if AP in Flexconnnect mode. So as long as your HQ APs are in Local mode then all those users traffic will be central switch for the given SSID. At branch those AP are in Flex mode, they will locally switched.
