Hi WLC 5508 with its AP3500 in network. The PC can receive two ssid from the AP.  When the PC uses first ssid, it would get 802.11a signal, while the PC uses the second ssid, it got 802.11n. My question is how we can change configuration in WLC so that the fist ssid has 802.11n and second one has 802.11a?  Thank you

we use gpo and certificate server to control access to our corporate wireless which works well for domain joined computers. Is a way to install the gpo and certificate on a device not joined to the domain?
I'm trying to setup another SSID on a Cisco 2504 WLC. I've mirrored (I believe) the settings of an already existing SSID/network with the difference of subnet, etc. The traffic is routed through a Cisco 2811 and various switches. The switch that identifies the VLANs, has also been configured accordingly. Could be problems in multiple places since I've done this a number of times, but never came across this issue.

To start, I can't ping the interface IP of that newly created SSID from any device, including the switch that the controller is connected to.

This is the config of the switch that the controller is connected to where the other networks work:

I figure if I can get to the interface IP (as usual), I'll be able to get to my DHCP server, get an address, and get to the internet.

Any assistance is greatly appreciated.
I have two WLANs at my site.  These are controlled by a Cisco WLC.  I am able to connect to the one of the WLANS and access the internet with no problem, but with the other WLAN, I can only connect, but am unable to get to the internet.  But if the Access Point is sitting in my office, I can connect and get internet access. This seems strange to me because the AP serves both WLANs.   I have uninstalled and reinstalled my network adapters.  I can ping both WLANs, but I can only connect to one of them and get internet access.  This is happening to no one else.  I figured it had something to do with my computer, but then I got another laptop put it in my office and it did the same thing.  What could be causing this?
We purchased a Kronos301 from Nexxt to be used as a repeater.  We follow the instructions but no internet.  We can see the kronos device in our mobile and even connect directly, but no internet.  We downloaded an apps that displays the wifi signal and also the kronos is read close to 190% mbps.

We have contacted Nexxt but it's a to/fro of emails with no solid answers.

  • When having a repeater configured to connect to the WiFi router, do the mobile devices also has to be configured to actual kronos301 device or the mobile just read in the amplify signal, no need to change the wifi setting on the mobile device?

  • also, when reaching the end of our wifi router signal range and supposedly entering the kronos301 range, there is no internet and the signal bars of the iphone/ipad stays the same or lower as to leaving the wifi router signal - how can we troubleshoot this?

Please advice
Hello, I got a few users that using Mac's os High Sierra and in their office, we have one guest Network, main office 2.4 and main office 5ghz but all day their systems keeps jumping on to the free Xfinity connection in the area. I have gone into network properties and removed all other connections and just added the main office connection and it still happens... what am I doing wrong?
Installed 2 APs and all worked fine

2 years later all is still working ok
iPhones etc can see APs all named different to the main router


Risco Viewpoint APs can’t see the SSIDs

He wap300n are wireless n and modern, surely these cameras just being installed are not G

Any ideas ?

Ubiquiti Nano-Stations M5 ( p-2-mp )

I have 4 Nano-M5s / 1 In AP mode and 3 in station mode ...

Until Monday the stations we are fine and connecting to the AP - 1 stopped.

Config looked fine / flashed to the latest firmware and even reset to factory.  Assumed that it was that M5 Station.  Took it back to our lab / configured another AP, and walla - it connected to problem.

So appears that something on the M5 AP is the problem.  

Is there a connection log that I can check on the station side ?

Any thoughts?
We have a Domain controller/DHCP server, Cisco wireless controller 2500 in our server room.

Already 2 wifi has been created using WLC wifi1 and wifi2 it has full access with out any webfilters.

I wanted to create another to Wifi_guest1 and Wifi_guest2, the users come to our office will connect this without password and with limited access of internet.

How can I create this can anyone give me steps or any suitable articles.

Thanks in advance
Anyone knows Aruba controllers well?   They normally pass through the same VLAN on the main switch, or the management VLAN.
Wonder why Aruba not recommending doing a direct heartbeat between Active and Passive controllers.  Using 7030 controllers at this point.
Normally I do a direct heartbeat between Cisco controllers.  But Cisco has a dedicated HA port for this.  Arubas not.  7030 controllers have 8 fiber and 8 copper ports.
 Anyone knows about it and have an advice?

Hi Experts,

I use a freeradius 3.0 and OpenLDAP-Server acting as 802.1x authentication server.
Windows OS use EAP-PEAP encryption by default. That means Windows sends out an encrypted credential to my radius server, and I can not decode it to a clear text password. But without a clear text password, how can I do authenticating in ldap server?
And Does Freeradius 3.0.x support CHAP/MSCHAP authentication against ldap?. If it possible, how I configure it?

Thanks so much!!
Hi, dear all

I am not a cisco wireless expert, our company want to build a cisco wireless,
the requirement as below:
two SSID, one is 'Office', for our stuff.  the other is 'Guest', for our Guest, 'Office' and 'Guest' are in the different vlan, 'Office' needs set Radius, Guest doesn't need.

I have a WLC 2500 series, and some AP,could one WLC do that? should I use two WLC to finish the work?
pls kindly give me some suggestions if you have experience about wireless design for company.

I am having issues with a Cisco WLC wifi deployment using radius authentication setup on an NPS. User certificates are installed by Group Policy and users are able to connect and work just fine however if they move out of range for an extended period of time and return the wifi SSID says connecting but never connects until the user manually clicks disconnect and connect again which prompts them with the certificate and asks to connect. In extreme cases users have to restart there PCs to reconnect to the wifi. PS. - Enable Fast Reconnect is checked under the Microsoft Protected EAP (PEAP) settings.
My internet at office was blocked from using utorrent by mikrotik Router, and i can't access any Utorrent site. Is there anyway i still can use Utorrent? (Microsoft Window 10)

We have a Ruckus ZoneDirector 1100 ver 9.5. Recently get trouble on preparing the landing page for guest to confirm T&C before using the free wifi service.

There is no problem on IE and Firefox for showing the page. For Chrome and safari, it cannot show the landing page. we need to remove all the cache / history before the page.

Any suggestion on it?
I asked this question concerning Cisco Wireless and restricting wifi users to specific OUs within my Active Directory. The response I got was: "Set you base OU to the "main" OU, set deny read permissions to the OUs you do not want for the account the WLC is using to connect and problem is solved." I've created a test OU, placed a test user in this OU, denied the account I've set up for my WLC full control on this OU and yet the user can still connect to the wifi. What am I doing wrong?

I've attached two sanitized screenshots showing my LDAP config on my vWLC and the Security properties on my test OU. Any help is appreciated.
NEC SL2100 over an Engenius EnStationAC wireless bridge is having issues with Echo on the VOIP phones.  The phones are PoE powered from a Netgear GS724TP.  All equipment is brand new (Phones and network).  The cabling is not new and has not been certified.  The VOIP phones over the internet and not over the wireless bridge work fine.  Only the 7 VOIP phones on the far end of bridge have echo problem.  It is intermittent, sometimes not at all for several minutes.  All equipment has the latest firmware.  All phones are on G711u codec.  A massive amount of monitoring and testing has been done so far, and their is no latency (1ms or less) or dropped packets (0%) ever.  The phones also can monitor packet loss (0%).  The bridge has RSSI of -34, and for testing purposes was lowered intentionally to -45 and -50.  Bridge is 100% stable with no obstructions between the buildings (Clear line of sight).  I have used multiple 5GHz channels, and their is only one other 5GHz broadcast anywhere near this building (That channel is never close in frequency and has been adjusted for testing).  The bridge is currently in 20MHz (have used 80MHz also).  There is no data devices of any kind on this network (Voice only).  The bridge is NOT running in Green mode.  Engenius has been working with me on this and doesn't have any more ideas to test.  I have tested a phone directly connected by 3' cable to PoE switch, and problem exists.  We are going to test directly in front of the bridge (with PoE …
I have to send SMS on table insert trigger via GSM modem in MSSQL

Is that possible and how
I have a Cisco 881-W ISR and have configured the wired portion of the router successfully.  I'm trying to configure the wireless portion, however, I can't login to the Privileged EXEC level of the AP.  I can only login to the USER EXEC mode.   I've tried to reset using:

            # service-module wlan-ap0 reset default-config
            # service-module wlan-ap0 reset

After doing those 2 commands, However, I can only login to AP USER EXEC mode using the username/password I setup in the wired config.  But, no matter what I try, the Privileged EXEC mode keeps returning that password is incorrect.  Any help would be appreciated.   Text file attached shows AP version information.
Hi Guys,

I have a small Python program running on windows 10:
This program observes and configures the wireless mobile access (mobile broadband) of the tablet it's running on.

This means:
- detect whether the SIM card is inserted.
- extract the EMEI, operator id, etc
- configure the APN, user and password
- check whether the mobile network is up or down

At the moment I have a solution using ctypes and a custom DLL, written by somebody who left the company many years ago.
Now this solution fails to work with a new tablet and certain SIM cards (Windows 10 itself has no problem using this tablet and this particular SIM card)

Therefore I wonder if there's any solution to  achieve above mentioned tasks with any of below:
- python ctypes
- win32 lib
- netsh
- powershell
- a cool command line tool with a permissive license
- .bat
- or anything else, that does not require Installation of Visualstudio or SDKs.

I would like to avoid anything that requires Visual Studio for compilation, as this is  rather complex  for long term maintenance. (Trying to recompile some old C code years later is sometimes tricky. and having to install the whole build environment on a tablet or having to build on a dedicated build host is something I'd like to avoid.

Thanks in advance for any pointers / ideas
