hello experts
i will using Cisco autonomous AP to setup wireless network for users, they will separated with VLAN for wireless they will using different SSID base on different department, i will using NPS as the authentication server, my question is how can i mapping different SSID to different policy on NPS?
on the NPS configuration wizard i noticed that there is a option calling-station-ID and called-station-ID, not sure i can using this option or not, but i don't know how to configure calling called station ID on SSID, please advice.

thank you

hi techs,
I am trying to play videos and pictures from my Note 5 to my Apple TV and suddenly it's not working in the last one year or so. The last time at work successfully was about a year ago and I was using allcast.  this week I've been trying to connect my phone again and no matter what I try my Note 5 will not detect the Apple TV and if some of the apps do list it it will not connect. I also tried my work Android phone which is I think an S7 and it wouldn't connect either. I have reset the network connections several times on both units and tried repeatedly with no success. I'm starting to wonder if Apple has made a change that everybody but me knows about. at this point what I think I'm going to do is buy the Chromecast and plug that in right alongside the Apple TV to see if I can use that to interface with my phone since all of the apps I've downloaded aren't working at all. My Note 5 is up-to-date with the most recent software and the Apple TV is also up-to-date with the most recent software and it is only about one year old. Any assistance with this issue is appreciated.
 thank you

There are several users with Macbook Pros in the office & about a week ago, once of them started having network issues.
The only thing he could connect to was a Win 2k8 server inside the LAN, that's used for remote access, when connected to network via Wifi. He couldn't get on Internet or couldn't connect to me via Instant Housecall. Once he plugged in an Ethernet cable, everything worked as was expected. He's getting IP address from the same server, whether wired or not, but for some odd reason it won't let him out to internet when on Wifi. Other mac users all are having no issues.
Any suggestions?

I want to add a device to a network that would NOT replace a Comcast router to allow secure wifi guest networking.
What I envision is a device that would be connected to a nework with say a 192.168.0.1/24 subnet using the Comcast router for DHCP.  The guest networking device would have DHCP server built in and dole out say subnet 192.168.2.1/24 addresses.    The device would also block any traffic from going anywhere on the 192.16.0.1/24 subnet other than the gateway out.    Does such a simple home /smb device exist?

Hi AP cannot join WLC. The AP is not in management vlan. I added command ip helper-address and ip forward usp 5246. It began to work. but I do not know why it cannot work now. The below is error message from the AP console. Thank you

Hello

We have a WiFi network with 802.1x authentication. The system runs with Mikrotik APs and authenticates against a Windows 2012R2 AD using the NAP service.

Overall it works just fine ... except for Windows 10 clients ! MacOS X, IOS or Android devices connect without issues (for instance my Mac just shows:  Authenticated via EAP-PEAP (MSCHAPv2)).

However when connecting from a Win10 machine (tried multiple laptops with various WIFI hardware) the UI prompts for user / pass and then returns a completely unhelpful message "could not connect".

The client machine event log shows (sorry it is a French W10 build)

Will your db performance match your db growth?

Will your db performance match your db growth?

In Percona’s white paper “Performance at Scale: Keeping Your Database on Its Toes,” we take a high-level approach to what you need to think about when planning for database scalability.

I connect the windows 7 with no AV protection and Windows firewall disabled to the LAN and it doesn't ping from any computer if it's on the wireless network via hostname or IP.  However, it does ping when I enabled the wired NIC.  Anyone see this?  The Access Point is in the next room over and I just replaced the AP/Router yesterday,  The old Sonicwall had no wireless connectivity issues for this particular computer.  This one doesn't either.  You can can still do all LAN and WAN surfing but you simply can't ping the wireless computer.  Oh, LAN and WLAN are both on the same segment.

A client has Comporium WIFI internet service package. They have 1 static WAN IP, subnet and gateway.
From this, they get 10 usable Static LAN IP's to be populated in 9 other separate WIFI routers. The main router gets the static WAN IP as it's static info, and an address pool must be created that is the range of the usable LAN IP's, for example, 204.158.15.10 - 204.158.15.19 in this main router. This is used in place of the standard 192.168.1.100 - 192.168.1.199 found in most routers. The client purchased 12 TPLink C1200 Wireless Routers, but these units will not allow the change in address pool to a LAN static IP range.

So we have the main router that has to have a static WAN IP. The address pool is setup with the range of usable static LAN IP's and then each of the other routers get setup with one of the usable static IP's. They want 10 routers in all. It seems they need a business WiFi router instead of a home based unit. Would prefer all 10 to be the same brand/model? Maybe just the 1 that has the odd settings for the address pool to be business class, and leave the other remaining 9 in place? They are all currently mounted on a wall.

Any suggestions on a router that can have a static WAN and then the address pool set to static LAN IP range?

We have (2) DAP-2553 DLink access points installed at opposite ends of a very large building.  Both have the same SSID, Security Settings, Password, etc.

Our laptops connect easily to our network via either one of these access points.  However, as the laptop moves and begins to lose it's signal from one of these access points, I would expect the other access point to provide seamless auto-connectivity to the device.  Instead the device simply drops its connection.

Am I missing something in the initial configuration of the access point?

DLink tech support has been terrible.  Their solution is for me to purchase 2 new access points along with a controller.  This would be a last resort due to expense.

Please advise.

I need to change a company's WIFI password.  They are using the Ubiquiti Unifi.  I am not the one who set it up, nor is the company who set it up still around.

When I run the Discover program, it locates the device, showing a particular user name and password.  When I click "manage" I get "The device is already managed.  Please reset the device to factory before perform L3 operation."

All I want to do is change the wifi password.  Seems inexplicably difficult, or complicated.  Anyone have experience with this device?

The network provider in my area recently shut down their 2G service and now my GSM modem doesn't work. Is there another kind of modem that would be compatible with a 3G network? I've looked a bunch of other places and it doesn't really seem to be terribly clear about it.

I have a cable connected to its wan port from a router with broadband


Should it be in one of the 4 other ports of its an access point ?

A customer bought this

Thanks

Here is a description of the setup I am having difficulty with - we have an Ethernet cable running from a wall jack going up a wall, through some ceiling tile and down another wall in a different room. The wall jack is live. If I connect my wireless router the computer sees the router but  the connection is unsuccessful. I have seen messages such as - limited access, unauthenticated, no internet access etc. I am getting a 169.xxx.xxx.xxx ip address.

This is what I have done to troubleshoot -
1) Reset and reconfigured the router
2) checked the Ethernet cable with a cable tester and found good continuity
3) tried a second router with no success
4) Uninstalled and reinstalled the wireless adapter in the computer
5) Tried different ports on the switch for the wall jack

If I use a shorter cable and keep the router in the same room as the wall jack I can connect. Is it possible my cable tester will show good continuity if both ends of the cable are set the same way but are not set in accordance with proper procedures? Is there something else I should be considering?

Thank you.

Trying to project my Wifi signal to reach 700ft with a beamforming signal to reach my property across the road from me. I was thinking of using a Wireless N600mW smart router R10000 from walmart. Would this be adequate or would this require a directional antenna to broadcast the signal?

Recently we deploy the 8 units Cisco APs and ship with the Mobility Express .Once we connected the uplink to core switch we able to get the IP address correctly in each vlan but we found virtual controller IP up and down and the wireless network also not stable.I try to unplug the uplink using my NB connected directly to AP switch then ping the virtual controller was stable then i try to plug the uplink to core switch again the ping is up and down.

I am sure that some thing is conflicting but don't know what is the cause.Please advise


We have configure APs switch all the port as below:
APs Switch
Untaged default  vlan 1
tagged management Vlan 2
tagged Internal Vlan 3
tagged Guest  Vlan 4

Core-switch
Port 7 (uplink)
Untaged default  vlan 1
tagged management Vlan 2
tagged Internal Vlan 3

Before moving to the cloud, it is important to carefully define your db needs, plan for the migration & understand prod. environment. This wp explains how to define what you need from a cloud provider, plan for the migration & what putting a cloud solution into practice entails.

i have the main wireless working fine.

I want the guest network to be on a different VLAN I created a wireless vlan and everything.

and I'm not getting any IP when I'm connected on the guest network .

Hello I have a startech wfrepeat300n wifi repeater in one part of the building to extend the wifi witch is hard wired from a belkin router my goal was to keep the wifi extender users away from the hardwired network users by having the extender using a subnet of 192.168.10.x and the belkin router downstairs to have subnet of 192.168.1.x now the problem I am having is some times the computers down stairs that are hard wired not using wifi are picking up ip address of 192.168.10.x and no internet so I fought with that for a bit, then just to get things working I changed the wifi extender to use the 192.168.1.x subnet with pool of 107-200 and the belkin router to use a pool from 1 - 100  now I am still getting computers hard wired not getting internet, I don't know what ip addresses the hard wired systems are picking up but I just had them remove the cable from the wifi extender and everyone hardwired connected .....What am I doing wrong ? I didn't think the wifi extenders broadcast back threw the cable to the switch to the hard wired pc's connected to it, I thought the extender would only broadcast to the wifi connections that are attach to it????

Hi

I've been working a lot with RADIUS and Wireless networks, but this one troubles me. The case.
WIndows 8 and Windows 10
Radius 2012R2
Aruba Instant AP

We user user account for logging in to network, and have configured wireless profile on PC to make it log on to wireless network before user logon. That works.
When a new users logs on wireless - he can log on even though credetials are not cached.
When a user gets a new password he or she can log on wireless
When a user gets a new password and will have to change after next logon - the user can log on after password is chaned

But when the user account is in the DirectAccess OU everything works, except form changing password after next logon.
Move PC in another OUT - it wokrs.

Not any error messages in Event Viewer on RADIUS server - other than ACCEPT.
move it to another OU - everything is OK.

any ideas? all GPOs are only for configuring Direct Access

Hi Folks.
I have a situation where our Corporate Wifi ( just a name)  is what our staff uses to log in and access our Network ( only with laptops). Wifi has Single Sign-On enabled so once they are logged in to their Ad account, they don't need to provide the credentials again on the same device. We have added a certificate as well for additional security.

Q 1- The users who do a password reset while being hard wired in network ( Ethernet Cable) , there is a delay where the wifi wouldn't authenticate them. Is there a way we can diminish this  time delay for password update for our Wireless Network. ( i would imagine it probably has something to do with the Radius Servers Settings).

Q 2- Some users just randomly loose connectivity to the wireless ( laptops are brand new , they connect to other wifi, they work just fine so its not hardware related).  And if they try to connect again they don't get authenticated. We have as a work around tried rejoining the computer to the domain + renaming the computer to something else and after that it also comes back to normal.

Q3- and lastly some users cant even connect for the first time. It just doesn't let them connect.

On the Radius Server, we have Network Policy set to authenticate using Only 1 condition
- that the user trying to access CORP-WIFI is part of the CORP-WIFI security group in AD.


Any help would be appreciated.

Thanks

It seems that some of the CLI commands have changed from the 3700 series to 3800 series Cisco access points.  Can someone help me with the follow:

3700 Series:
To change the IP address: capwap ap ip address 10.0.0.1 255.255.255.0
To change the gateway: capwap ap ip default-gateway 10.0.0.2
To change the primary controller: capwap ap controller ip address 10.0.0.3

3800 Series:

I setup wifi in a 4 bed 2 storey house & there have been alot of wifi issues!
Multiple devices & 4 heavy users.
Apple Tvs, Ipads, Macbook, Iphones & 2 windows laptops
Constant drops on wifi & constant reboots of Fiber router.
EG Freezes when watching netflix & need to connect to another SSID.
They get approx 50mb download from the router (which also has wireless enabled)
They didn’t want to wire so i used 4 tplink powerline av600’s
(i’ve used them before with little issues)

http://uk.tp-link.com/products/details/TL-WPA4226-KIT-V1.2.html

So i’m thinking of just swapping out the AV600’s with Archer C2 wifi routers & using standard tplink powerline plugs

http://www.tp-link.com/us/products/details/cat-5506_Archer-C2.html

I setup as Access Points.
I disable dhcp, wan, use separate channels, disable firewall,nat,guest network. I set dns to 8.8.8.8 & 8.8.4.4
All have seperate SSID's. A mix of 2.4 & 5G.
I set the 2.4 channel width to 20mhz
I’ve been testing on my home network & it works fine then just loses connection for a couple of mins.
Happens every hour or so.
I get obscure DHCP error messages in the system log.
I upgraded the firmware & it’s more stable but not perfect.
I try continuous pings from a pc & ipad & they seem fine?

Other than hard wiring is there any advise to minimise issues?
Or is it a limitation of powerline?
