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.

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.

  • My printer can not connect to WiFi if there are two or more APs with same SSID

    I tried to connect my printer to WiFi but failed.
    My network has more than 2 WiFi APs and all the APs have the same SSID and security settings.
    I found that the printer can connect to WiFi only if I left one AP on and turn all other APs off.
    Other devices like notebooks, smartphones all works fine with these APs.
    Any solution to solve this problem?

    No, I gave you a solution to try, you rejected it. BTW using channel 3, it is getting clobbered by all APs on channel 1 and channel 6. If you use channel 1, you only have other APs on channel 1 to contend with. That's why you should only use channels 1, 6 or 11 on the 2.4GHz band.

  • 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.

  • No auto-connect to WLAN with hidden SSID

    I work in Infrastructure Services at the IBM Zurich Research Laboratory.
    Across IBM, there is a standard setup for wireless LAN access. There’s a public WLAN that provides access only to the internet; and there’s a private WLAN that provides access to both the internet and the corporate intranet. The private WLAN requires authentication via WPA/WPA2 Enterprise using LEAP or a certificate, and has a hidden SSID.
    Both WLANs are served by the same access points.
    The iPhone and iPod Touch do not automatically reconnect to the private WLAN with the hidden SSID.
    Each time the iPhone wakes from sleep, the user must connect manually to the private WLAN. The user must go into Settings and then Wi-Fi, wait for the private WLAN to appear in the list (there’s always a delay) and then tap on it. Also, if one opens Mail or Safari application before connecting manually, the the blue pop-up list of available networks will not include the private WLAN with the hidden SSID.
    This is a major inconvenience, because it adds half a minute or more to each operation that requires network access. Checking one’s email—something that should normally take no more than ten seconds—instead takes a minute or more, depending on how quickly one manages to connect.
    This bug also results in needless expense, because network operations that should go over the local WLAN often go instead over the mobile phone network.
    The inability of the iPhone/iPod Touch to reconnect automatically to networks with hidden SSID has been a problem since the original iPhone came out.
    This problem is an obstacle preventing wider adoption of the iPhone within IBM.

    Anyone have an update on this ?
    I have a new 3GS with 3.1.2 and have the same issue. I haven't tried the factory reset yet, but from this link;
    http://l00pback.wordpress.com/2009/10/14/iphone-3-1-bug-no-auto-reconnect-to-hid den-ssid-wireless-networks/
    “Work around”: Not really a workaround, but a sightly less frustrating way of reconnecting… when in range of the network… recreate the network by entering the SSID and leave out any of the security stuff then click Join. The join will fail (for obvious reasons), but will then “remind” the phone that that network exists and will then connect using the previously configured settings."
    takes some of the pain away.

  • Flex Connect Across Multiple VLANS same SSID

    I just need to find that if we have flex connect setup for differnet vlans using single controller, will roaming works when client connects to AP in a differnet VLAN but using same SSID.
    Example below:
    1) Client connects to AP on specific SSID mapped to VLAN 100, get an IP address ..all good at this point
    2) Client walks and connects to a differnet AP on same SSID but mapped to VLAN 200...at this point I observe client doesnt get a new IP address in fact it retain IP from step-1 and there is no connectivity
    3) Client walks back to first AP and connectivity is restored
    Why in step-2 client doesnt gets a new IP from VLAN 200 even when it shows connected to AP.

    Just to add to Rasika.... L3 isn't supported....I just ran into this a few days ago.... clients should request another dhcp when roaming to another FlexConnect AP that is mapped to a different VLAN.  The issue is, that some clients don't try to renew their dhcp address and gets stuck with the default 169.x.x.x.  I see this with Apple devices in general and what we are going to do is get rid of the multiple vlan setup (vlan per floor) and create a bigger vlan that the SSID will be mapped to.

  • 3 wifi networks (no password) with same ssid  how to choose? in Mavericks

    I have an issue-- at a location where I sometimes work, the wifi (which is set up for guests, so no password) has the same SSID/name as 2 other networks in  range.  I'm using Mavericks on a macbook.  using wifi explorer I can see all 3 (one channel 1, one channel 4, one channel 5), but under the system utilities it only shows one of the 3.  It is connecting to one that doesn't seem to work.  I know that one of them works, because my iphone is connecting to that one and works ...
    I tried disconnecting and reconnecting wifi 4 times on my macbook hoping it would reconnect to the one that works, but no luck.  Guessing it is connecting to the strongest.  Is there a way to choose which of the networks to connect to manually???  set the channel or something???  This is frustrating.   As I said I can see all 3 in wifi explorer, but in OSX sys utilities I only see one instance of that ssid.
    Thanks

    No, generally speaking it's not possible to manually choose what network you want to connect to when they all have the same SSID. Some apps that are similar to WiFi Explorer but that offer the ability to join the networks they find might let you choose, but it will not work very well since it ends up conflicting with what the system does, which is to automatically choose the "best" network based on different factors such as signal strength and security configuration. This "best" network is the one you see in the menu of the Wi-Fi system bar icon.
    Are the two other networks in range also part of the "guest" network? If not, and they're not under your organization's control, then the only solution is to have the "guest" network use a different SSID to make it distinguishable from the others.

  • IPOD touch OS 3.1.2 can't connect to wifi with hidden SSID

    This isn't so much a question, rather than a complaint. It seems like other people have the same issue. I have a Linksys router configured with hidden SSID and encryption. My newly purchased iTouch can't re-connect to it after I cycled the wifi settings (or cycle the power). I have about a dozen other wifi enabled devices, some as old as 5 years, that have no problem reconnecting to the hidden network. I find it unbelieveable that this fancy new OS can't support something as common as hidden SSIDs. Now I have no choice but to broadcast the SSID which is not something that I wanted to do. I hope Apple will fix this eventually.

    I think I may have figured out part of the rhyme, but the reason is still bewildering. Nobody is stating the router they are using. I figured out a clue to this. I was using the D-Link DIR-825 router with iPhone os 3.1.2 and had no trouble at all with my hidden SSID. Two weeks ago I purchased the Linksys WRT610N, and the iPhone will no longer automatically connect to the router unless I enable broadcast SSID. So why did the iPhone connect to D-Link and not Linksys automatically? There's got to be a difference in the way these companies are treating hidden SSID. The iPhone and iPod Touch will recognize one and not the other. Now it makes a little more sense as to why some people are ok and others not.
    What's more peculiar is that my laptop and wireless bridge both work fine with the hidden SSID from both routers. It's only the iPhone that is being finicky.

  • Advanced wireless config - 2 base stations with same SSID

    Hello, in my home I have 2 stations running with the same SSID (one is a repeater)... Is it possible to be able to select the station I want to connect to??? With "Internet Connect" I can't.
    Thank you

    Rafael
    Welcome to discussions. When you say repeater do you mean relay? You are not connecting to a base station per se but a network. If your second station is configured as a relay station or in such a way so as to expand your existing network, the answer is no. However, you can use your second station to create a separate network you can connect (you will not be able to use it as a relay station, for example, though).
    My answer is kind of generic. If you can mention what you are trying to achieve maybe I or somebody else (more likely) can come up with suggestions.

  • Access Connection​s Problems With Windows 7 and Microsoft Security Essentials

    There appears to be a conflict with Access Connections and Microsoft Security Essentials which causes Microsoft Security Essentials to generate high page faults and high CPU usage, and prevents normal operation of Access Connections.
    After fresh install and reboot Access Connections would not launch, and when cursor was moved to the taskbar, the cursor pointer changed to a spinning loop.  Clicking on the Access Connections gadget did nothing. Looking at Task Manager, Microsoft Security Essentials program msmpeng.exe was experiencing 5000+ page faults per interval.  Terminating msmpeng.exe immediately caused Access Connections to launch.
    System configuration: Lenovo Thinkpad x200s with Windows 7 Ultimate 64 RTM (installed with a fresh install) with all current updates, and all updates from Leovo including Access Connections V 5,42 Build 6JC725WW,

  • How to connect many devices with only one FW800 port in iMac?

    Hi,
    I am upgrading to a new Intel iMac from a 2004 vintage Dual2.0GHz PowerMac. I currently have 8x d2 Quadra drives chained by FW800, and 2x Iomega drives connected vis FW400 hub which also connects HD cams.
    My questions is that with only one FW800 port in iMac, I think my devices connectivity is the following?
    (1) Get a FW 800 hub (I can only find 2 port ones at the Apple store and BestBuy)
    (2) Connect the d2 Quadras to one port of the FW800 hub
    (3) Get a FW 800 to FW 400 cable
    (4) Connect my 6 port FW400 hub to the 2nd port of the FW800 hub
    Thanks for reviewing this solution, and I would also appreciate other suggestions or hear about your experiences if you have a similar set-up.
    Will

    In addition to your listed considerations, you should consider the following.
    Many storage needs do not required FireWire 800 speed. For example, USB 2.0 works fine for your Time Machine backup drive. If you are just storing user data such as your iPhoto or iTunes media files, USB 2.0 is more than fast enough. So, as much as possible, if any of those external drives have USB 2.0 connections and the data storage does not need FireWire 800 speed, offload as much as possible to USB 2.0. I used to be a +FireWire snob+, but since getting an Intel iMac, I find that USB 2.0 works quite well for most data storage purposes.
    There are new hard drives that are power efficient and as large as 2TB. Consolidate your data storage needs onto a smaller number of very large drives, partitioned as needed. This will make your setup more reliable (smaller number drives), and save reduce power consumption. If any of your current externals are SATA, you can probably replace the existing drive with an extra large one.
    So, I think you setup should be, extra large FireWire 800 drive connected to the FireWire 800 port directly. Using a 9-pin to 6-pin cable, connect the FireWire 400 hub. Connect any non-storage FireWire 400 devices there. Do some data transfer testing to make sure having the 400 hub there on the chain does not cause the 800 connection to slow down.
    Connect other drives as needed using USB 2.0, existing or new. Retire the smaller of your external drives.

    I am having trouble with an xsl stylesheet. This is what one of the rows of my output xml document looks like

    Does anyone know how I can access the 2nd CCDESC ("CHARDESC2") . When i run this in the workbench I can only ever access the first CCDESC, it acts like the 2nd isn't there. However I was also using a 3rd party xsl editor called "XMLSpy" to look for other possible solutions and when i render it with XMLSpy, everything is displaying correctly. Is this some sort of limitation of the workbench? Any help would be much appreciated. Thanks

    Muzammil,
    Thanks for the response. I may have explained my situation a little poorly. I am not trying to access the 2nd CCDESC within the workbench via a repeater or such. It is after the XSL renders the page that I don't see the second CCDESC. When the XSL renders the page through Internet explorer i get something that looks like the following......
    Res # 1
    CHARDESC1 
    When I render it in the application XMLSpy it shows both CCDESC's like follows.
    Res # 1
    CHARDESC1 
    CHARDESC2
    In XMLSpy if i change the line of xsl code from      <td align="center"><xsl:value-of select="CCDESC[position()=$i]"/>  to       <td align="center"><xsl:value-of select="CCDESC[2]"/> the page is rendered in XMLSpy with both labels the same as follows.

  • PinListener triggers many times with same value, then segfaults
