Which access point does it please??!

I am assigned to implement a wireless network and i intend to use repeater mode in the building but, there is one problem, iam not sure which access point supports more than one MAC address to repeat to and the other to recieve (trying to input more than one MAC address in each AP for redundancy).
Does anyone know anAP that supports more than one MAC address for repeating mode?
Thanks.

Hi aeronav01,
What pinkyzeny suggested is fine. Bridge mode configuration might not be the right one for the set up you want. WAP300N has a repeater mode. You just have to make sure that the access points configured as a repeater should be facing in different directions to avoid interference. Or you may just configure it as a plain access point and create different networks for each. You may also refer to this link for Bridge Mode .

Access Connections 5.61 - Which Access Point am I on?

I have 3 access points in my area (a mobility center), and it appears only one of them is working. When I go near that one I can get connected but when I logoff and walk near the other two, nothing. I see all 3 listed at 100%, but is there a way to specifically connect to one access point, as it appears to always choose the closest (whether it works or not). I am using Access Connections 5.61. I just noticed there is a field where I can put the preferred MAC address in, but that secion is greyed out. Can I at least determine which access point I am connected through when I do get connected? Thanks in advance.

Hi,
You can do it in the way, that you configure 3 different wifi connection for each AP and then you configre the on, that you want to use to be always the prefered using following method:
in this situation please configure AC in following way:
- open Ac->Tools->Location Switching-> in the screen make sure, that the location switching in enabled and the key point is, that you specify the correct Wifi AP in the "Preferred WLAN profile".
Let me know, if you have reached to this situation and cold configure it in the correct way.
Cheers

Which Access Point?!

I am assigned to implement a wireless network and i intend to use repeater mode in the building but, there is one problem, iam not sure which access point supports more than one MAC address to repeat to and the other to recieve (trying to input more than one MAC address in each AP for redundancy).
Does anyone know a Cisco or non Cisco AP that supports more than one MAC address for repeating mode?
Thanks.

Depending on the size of the building, that approach may not work well in practice.
Ignoring the potential bottleneck of the 100/1000 connection between the single AP and the WLC/Switch (depending if Autonomous or WLC), repeating the signal X amount of times also reduces the speed/throughput as mentioned by Leo above.
If you only have a handful of clients using this Wireless Network, it may be fine but its definitely not suitable for a larger deployment where you expect to have maybe 10-15 people per AP.

Which access point do i use????

ok then i know how to access the internet and live messenger when i am at home as i use my bt homehub as the access point.
but when i am away from home i dont know which access point to choose, these are the options i get -
02 MMS
02 MOBILE WEB
O2 PRE PAY MMS
O2 PRE PAY WAP
O2 WAP GPRS
O2 WAP GPRS STREAM
I am on o2 pay as you go. i think i managed to access it the other by accessing pre pay mms, but it used nearly £5-00 credit in just a few minutes.
I really need to be able to acces the internet away from home, to use live messenger and also the pre installed satnav, as it always gives the message no route found, must connect to the internet to plan route

Those with "MMS" are for sending and receiving multimedia messages (MMS = Multimedia Messaging Service).
Those with "WAP" are for "Wireless Application Protocol" and the connection go through the network operator's WAP gateways, which may limit what protocols are passed through and they might also do something to the content.
So, for regular Internet access, without knowing O2, the "O2 MOBILE WEB" is most likely to give to a straight-forward, pure Internet connection. No idea what kind of rates O2 will charge, though. Call them and ask, or check their web site.

Locating failed wireless login attempts and which access point they're hitting

We have a cisco 5508 WLC with about 190 access points. They use Cisco Secure ACS to authenticate Microsoft Active Directory logins. We sometimes get non-normal accounts attempting to login to our wireless but are unable to figure out which access point they're hitting.
When I look at the failed attempts in our Cisco Secure ACS 5.5 Radius Authentications report, I don't see an IP address, just the MAC address of the failing device. Is their a way to configure either the WLC or the ACS box to report either the IP address or MAC address of the access point they're connecting to?

Is this something I need to set the ACS or WLC to send? When I go to Other attributes in the "Authentications - RADIUS - Today" report, this is all I'm currently seeing.
Other Attributes:
ACSVersion=acs-5.5.0.46-B.723
ConfigVersionId=3
DetailedInfo=Invalid username or password specified, Retry is allowed

Which access point is better for hospital environments?

Folks,
I have a customer in hospital, who requires to have wireless deployed everywhere. The fact is , customer is budget concious, so I designed in such a way to place it in corridors , so that wireless coverage could get inside the rooms, but the doors are fire-proof which blocks RF .
What are the best practices in deploying AP's in hospital, for eg: is it safe to install AP's next to Medical Imaging Room or other devices which may cause interference
Which model is suitable for this sort of installation?
Thanks,
SID

Hi SID,
Please consider in your budget for a Wireless LAN Site Survey. WLAN Site Survey will allow you to better understand WHERE to deploy your AP's and HOW MANY AP's to deploy. When deploying an AP, also bear in mind for AP failures. You can address this issues with either keeping "spare" stocks or putting additional AP's per floor so when an AP would fail, the WLC will calculate and increase the transmission power to cover the loss of an AP.
In regards to what models to buy, I'd recommend looking at the 1140 or the 1250. These AP's are geared up for Draft N (2.0 Ratified).
For AP's that are geared up for 802.11N (Draft 2.0):
Data Sheet Cisco Aironet 1140 Series Access Point

http://www.cisco.com/en/US/prod/collateral/wireless/ps5678/ps6973/ps8382/product_data_sheet0900aecd806b7c5c.html
If you are going to choose the 1250, note that the Antennaes are optional. Here's some information regarding them.
Antenna Product Portfolio for Cisco Aironet 1250 Series Access Points
http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/at_a_glance_c45-513837.pdf
The AP1250, when operating with 2 radio modules on Autonomous IOS, requires a minimum of 18.5 watts (ePoE). So you'll need either a Power Injector or PoE switch that will support enhanced PoE such as the 3560-E or 3750-E.

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

How to tell which lightweight access point is offline?

I may be missing something really obvious here, but is there a coherent way to tell which access point has dissociated from a Cisco controller? For example - i have a controller here with many hundreds of access points being installed. If i have say 500 access points associated and i unplug a random one, the "all APs" in the controller summary will simply drop to 499 total, not 500 total, 499 up and 1 down as i would have expected - it's therefore a bit of a nightmare to trace a missing access point when the number suddenly drops below what i am expecting based on the number i know are physically installed.
Hope that makes sense!!! Appreciate any guidance you guys may have!

Several ways of doing this:
1. If you have a network monitoring tools like WCS/NCS/PI, then it is Cisco's preferred method. You can enable WCS/NCS/PI to email alerts (personally, I wouldn't recommend it).
2. WCS/NCS/PI uses SNMP to poll the different WLC in your network. You can craft your own to generate your own system (what we are doing now).

Determining which wireless access point a computer is connected to?

Apologies if this is posted in the wrong forum...
I am working in a large open space where there are multiple overlapping wireless access points -- not Airports but from another vendor. Unfortunately, several computers are experiencing wireless performance and dropout issues. I think the problems may be because the laptops (both PCs and Macs) are connecting to a more distant access point across the open space which is more "line of sight" than the closer access point. We can't confirm this theory, however, because I can't pinpoint which access point we're connecting to. This is possible with a PC, but I can't find such a piece of software for my PowerBook. Is anyone aware of such a utility?
Thanks so much.

Air Traffic Control widget. Search the download section for this useful widget. This widget lists all wi-fi access points, shows what channel each one is on, what the signal strength is and some vendor information.
Whichever access point you are connected to is listed in italic on the list. I like the fact that it is a widget as it makes it very easy to access.

Can a single Access Point support both bridge mode and Access Point mode at the same time

Hi Guys
Does anyone know which access point can work in both bridge mode and AP mode ?
Cheers

Well what are you trying to cover. If its really a large outdoor area, then look at the mesh AP. Those require a WLC. Autonomous or stand alone ap can perform bridging on one radio and client access on another. You can also look at AP that support indoor mesh that also controlled by a wlc. If your putting APs outdoors, then look at the outdoor mesh.

Specify an access point.

Hi all,
I have a wireless network in my house, with a wireless extender from Dlink to reach those out of the way places.
I'm wondering if there is a way to specify which access point you connect to.
One things to keep in mind:
The extender has the same ssid as the main access point.
On my xp box, I there is a spot to specify the mac address that you want to try first ... just trying to find the same thing using OS X ... 10.4.5
If you're wondering why ... the extender only has half the available bandwidth because of the way it works .. half to connect back to the main router, other half for people connecting to it.
Thanks in advance for your help.

iBook G4 800Mhz Mac OS X (10.4.5)

In reality, this shouldn't even be a user option but my guess is XP doesn't do wifi correctly without some manual assistance. The wifi subsystem of the airport card should automatically detect multiple access points for a single SSID and dynamically switch based on of the signal between the two.
Of course, this is tricky if the extender isn't full bandwidth as I'm not sure the algorithm checks bandwidth (i think there's an assumption that a network with multiple access points wouldn't be unbalanced).
I'm be curious if anyone knows if it does. One thing you could try (you'll need someone to help) is to get close to your extended and have someone disable the primary. If you notice a temporary signal stall and quality change it means that you were still on the primary. You could also monitor he base station ID in the internet connect.
Rinse and repeat until you find the range balance and then decide on your own if its appropriate.

Problem with PowerBook (but NOT MacBook) and two access points on network

I recently installed a wall-plugged ethernet adapter system (Netgear XE104 and XE103) and plugged a wireless access point (Netgear WPN802) into one of the adapters (in the part of our house where we lacked a wireless signal) in order to extend the range of our (DSL) wireless network. I configured this new access point--disabled DHCP, assigned an IP address to the access point that does not fall into the wireless router's IP adress range, put the wireless router and access point on different channels (6 and 11), and made sure the router and access point had the same SSID.
I have had no problems using the resulting setup with our new MacBook--everything goes as planned. BUT I am having a terrible time with my PowerBook G4. It has a really strong signal everywhere, but when I open my browser it says that I am not connected to the internet. The problem seems to be that my PowerBook refuses to change channels once it connects to one. I installed iStumbler to see if I could manually control which access point/channel the PowerBook uses, and, while I can track the signal strengths for both access points, I can't get my PowerBook to switch from one access point to the other.
I've tried just about everything I can think of. I suppose I could try giving a different SSID to the access point (and then try to switch with the airport menu in the toolbar), but I would like to avoid this if possible.
I would really appreciate any advice you have. Thank you!

Can you connect if you temporarily turn off WEP or WPA?
This will determine if it is a WEP or WPA issue.
Does your PC support WPA, from both a hardware and a software perspective?
The problem you are having probably lies with the encryption key.

Bootup order on Cisco Aironet Access Points

Hello folks
Could you please help me in clarifying the bootup order on Cisco Aironet Access Points
Does the SNMP Agent on the device start before the Startup config is copied to Running Config ?
Because everytime the Cisco Aironet Access Point restart , SNMP trap is generated from Admin down WLAN interfaces (Dot11Radio1/Dot11Radio0) mentioning "Administratively down " .
So my best assumption is that
Access point Restarts - > SNMP Engine starts -> Startup Config is copied to Running config -> Interface is made admin down -> SNMP Trap is sent
Is that correct?
Please help !

The Clean Access Manager (CAM) manages out-of-band Clean Access Servers (CASs) and switches through the admin network. The trusted interface of the CAS connects to the admin/management network, and the untrusted interface of the CAS connects to the managed client network.
When a client connects to a managed port on a managed switch, the port is set to the authentication VLAN and the traffic to/from the client goes through the Clean Access Server. After the client is authenticated and certified through the Clean Access Server, the port connected to the client is changed to the access VLAN. Once on the access VLAN, traffic to and from certified clients bypasses the Clean Access Server.
In most OOB deployments (except L2 OOB Virtual Gateway where the Default Access VLAN is the Access VLAN in the Port profile), the client needs to acquire a different IP address from the Access VLAN after posture assessment.
For Real-IP/NAT-Gateway setup, the client port is bounced to prompt the client to acquire a new IP address from the admin/access VLAN.
The below URL describe the configuration steps needed to set up your OOB deployment:

Firewall considerations ZfH Access point to MGT server

Hi there,
According to the TID10095278 the ZfH access point talks to the ZfH
Management server on port 2398. I presume the Access point does all the
initiating to the Management Server.
I know to can use HTTP encapsulation on port 80 but I've never got that to
work.
In the case where you want to locate an Access point on the public side of
a firewall and the Management Server on the private side. I presume an
inbond rule of 2398 needs to be allowed using TCP.
In the paragraph in the TID "In some cases the ZfH will send a UDP packet
to the Access Points over port 2398, but this is to optimize some things,
and will work correctly if this packet isn't delivered correctly." I'm
presuming this means from the handheld to the access point.
Does anyone have any thoughts on this?
Thanks,
Fred.

N95 Wifi, home network and hidden access points

Hello-
Just picked up a N95 and having some problems. First, my home network doesn't broadcast a SSID. I stumbled across the home network option and was able to configure it. However, it's never an option when I need an internet connection; e.g., it never shows up in the wlan list.
So, how do I congigure a hidden access point so I can use it? The user guide says you should be able to do it manually, but doesn't go into any details.
Secondly, exactly what is the home network setting for and why is it separate from the other wlan settings?
Thanks,
Jay

Jay,
I too have a hidden network (SSID not broadcast), the N95 seems to have a problem with this. It may or may not show up on the active standby screen (on my Voda N95, it shows up when I take my sim out!).
To configure your accesss point :-
Tools / Settings / Connection / Access Points
then Options / New access point
Connection name
(enter a name, whatever you want to call it)
Data bearer
=wireless LAN
WLAN network name
(enter your SSID here)
Network Status
(public or hidden)
WLAN network mode
(Infrastructure or ad-hoc. If you're using a router, infracstructure should be the one you want)
WLAN security mode
(Open, WEP, 802.1x or WPA2. Check your router)
WLAN security settings
WPA/WPA2
EAP or Pre-shared key (consult your router)
EAP plug-in settings or Pre-shared key
(which one you get depends on what you set above)
WPA2 only mode
(leave alone)
Having done all this it still won't show on the active-standy screen (at least it doesn't on mine) in the WLAN section BUT if you know try and surf the web it should ask which access point you want to use - assuming you've got it set to 'always ask'. What this seems to do is only list the connections that it can find (i.e if you've got a 'Starbucks' and a 'home' connection defined, it'll only show 'home' at home and 'Starbucks' when you're getting your latte. The standby screen may show, how to decribe it, a four leaf clover near to the battery level indicator, this is the indication that it's either found or connected to your wireless lan.
I think the 'Home netw.' option is for use with the Home Media Server application supplied on the CD. I haven't tried it so can't confirm for sure.
Hope this helps,
Simon
