I have searched, attempted, etc. for countless hours prior to posting my question here. I am looking to add a Guest SSID/wireless network to my existing topology. For whatever reason, I cannot seam to get anywhere using the Cisco configuration guides. One in particular, https://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-vlan/70937-guest-internal-wlan.html#configs

It is rather dated as well.

Here is my current setup:

ISP--> Cisco ASA --> Cisco Router --> Cisco Switch
Cisco WLC and Cisco APs connected to Cisco Switch

The ASA and Router are on network, and the port from router to the switch are on network.
I have a Win 2012 Server on the network that acts as my DHCP and DNS server.
I have 3 Cisco APs that are on the network. (my management interface on WLC is on the network as well)

What is the best method to incorporate a guest wireless network? Also, to correct my above setup (granted the management interface on WLC should not be on the same network as everything else)

I have attempted to create VLANs, but end up losing connectivity to the network, and there are two many possible areas of failure given all the components.

Should the router be the DHCP server instead of the Win 2012 server?

Please advise!!

Thank you in advance!!

I have a SonicPoint ACe and we're using it as an AP for public wifi, so it's not attached to the SonicWall FireWall, since the SonicPoint is in standalone mode, I can't enable the 2.4/5 radios in wireless router mode.
Need to change WIFI properties to metered, on a group of laptops. Hoping for a batch file, or small script, an assistant can run on each. Hard drives are too small for Win 10 auto updates, attempting to stop auto download of them, so we can do them in a controlled, scheduled fashion, instead of when students are trying to use.
I have a wireless modem/router which manages the main part of my network.  Its LAN IP is and it is a DHCP server.

I have also connected a TP-Link C60 Wireless router via cable to the modem/router.

I am wanting to configure the TP-Link wireless router to give wireless access but then have the DHCP managed by the modem/router.

At the moment I have the TP-Link router getting a WAN IP of from the modem, but then the TP-Link is issuing IPs to wireless clients in the scope.

Does anyone know if I can get it to simply act as a wireless repeater for the modem rather than have its own DHCP scope?

Warning: If your device uses WiFi, it's at risk!
News broke today about the Krack Attack, a new cyber threat that can decrypt and potentially view everything users are doing online. The Krack Attack preys on a weakness in WPA2 protocol. Hackers near the vulnerable devices (Android and Linux are at greatest risk) can retrieve sensitive user data and information.
Steps to Protect:
1. Apply patches as they become available. For phones and computers, the patches will come in the usual update format. For wifi routers, the manufacturer's website will have the patches.
2. Don't use public WiFi, especially for sharing or sending any sensitive information.
3. Double check that you are browsing with HTTPS. If you are unsure, install this plug-in to encrypt your communications with major websites and make your browsing more secure. https://www.eff.org/https-everywhere
4. Otherwise, use Ethernet.

We recently implemented EAP TLS in our Cisco WLC/AP WiFi environment. I was having a problem where at least once a day I would get dropped from the network and it wouldn't automatically attach. I believe I have this solved but I would like help understanding why it solved or if you think I'm just hitting a lucky spell that's fine too.

The fix seemed to be - in Windows 7 I ran msc and then added in the certificate snap-in. I browsed to Personal folder for certificates and there I found two certificate: *.allyoop.com and *.lab.allyoop.com. I deleted the *.lab.allyoop.com certificate. And now my EAP TLS WiFi auto attaches in the morning without my having to select one of those two certs in the morning. But additionally I am staying attached the entire day without getting detached.

Can one of our WiFi experts comment on how the deletion of the lab certificate might have improved the stability of my EAP TLS WiFi connection? Thank you
I manage I.T. for a small non-profit theatre company, and I am not particularly strong on networking. We have a single 100 mbs internet connection (Comcast) and support both wired ethernet and wireless access. Our boxoffice computers and a couple of administrative computers are connected to the network via ethernet. We also have actors and staff who connect various devices via wifi. The problem is this: the boxoffice computers are critical because if we can't sell tickets, we can't exist. But there are times (e.g., when rehearsals are over) when everyone jumps on their wireless devices and use all the bandwidth, so boxoffice and admin computers grind to a halt.So my question is: is there a way to place a limit on the amount of bandwidth available to the wireless routers (we have several access points across our campus) and maintain availability of bandwidth to the ethernet network? The people and devices accessing via wifi is constantly changing, so setting individual limits by IP is not practical. Any ideas would be appreciated.
I downloaded Intel® PROSet/Wireless Software and Drivers for Windows 7*
Version: 19.70.0 (Latest) Date: 7/11/2017 - ran install. But still my WiFi driver
remained at 15.17. So then I tried to manually update the driver. But when I
point to the dir Windows preemptively says it has the latest. Is doesn't. What
could be going on?

Helping a friend a couple hours away add encryption to their wireless network using an apple airport as the wifi source.

They have some wireless cameras (and some wired... I am hoping these are the same model cameras both with wifi and RJ45?)

using the foscam camera's web interface, I set the wireless encryption key on each of the wireless cameras - a 7 character password that they accepted.

Then tried adding the encryption key in his airport. But it wanted at least 8 characters.  We changed the password to one that has 8 characters but are now unable to access those wireless cameras.

Any ideas on how to get into the web admin / set them to the new 8 character wifi password?  And again, they are 2 hours away and not tech savvy. I really don't want to have to drive out there.

I’m thinking get him a 100' cat 5 cable and he'd run it from the airport to each camera’s RJ45 port then they’d get on the network, maybe with a different IP address and I can remotely get into the web interface and change the wifi password??

Or because they are set up for wireless now, they ignore activity on the RJ45?

Other ideas?

Hi everybody!
this is Latif, I am going to configure Cisco Access Point Series AIR-LAP1262N-K-K9, But i am not able to login and i have forget the user name and password. so, please help me to reset my Access point.

Many thanks in advance
Run all the updates from the dell web site and windows 7 but still no internet. There are other computers connected with the same wifi.
When I am attaching to my WLAN with EAP TLS enabled - my PC (and I hear Macs) are asking to confirm the certificate to be used. This prompt I am seeing pretty much every morning. Then I am seeing this prompts part way in the afternoon. I could swear I did not get prompted to validate certificate up until recently. Any thought on why windows would prompt me for the certificate instead of just attaching to the network as desired?
We have three Cisco ACS RADIUS servers ACS1 ACS2 and ACS3. ACS3 is the active monitoring and reporting server.
But I notice on the WLC that it points to all three ACS servers for RADIUS Accounting. I think this should only be
sending to the monitoring and reporting server - correct? Any insight appreciated.

We have a sonic wall that is transmitting bad frames.  How would I go about troubleshooting this?  this is only happening on the TX and not the RX.

Also, this older sonic wall is used as an AP connected via lan to another sonic wall.  We are setup this way because we disabled WIFI on the main unit since the WIFI was giving us troubles.

We have some printers that we'll be using in warehouses across the country.  All of our warehouses have Cisco 2602 access points.  However, some of these special printers do not have wireless, only Ethernet.  I need a business solution for making these Ethernet only printers wireless.  Do I just get a Cisco AP and make it a bridge?  Thank you.

hello experts
in my AD i have a service account for example name guest, it used to authenticate guest WIFI, i am using NPS as the radius server, while trying connect to the wireless network after input username and password, IOS and Android device will pop up a notice about the certificate, once i click trust then network connected, but for windows client only notice me can't connect, except i create the wireless profile manually and uncheck "verify server certificate" then network works, for this is for guest only so i can't let them setup it themselves, so i think i need to do something with my NPS server. does it necessary i purchase a certificate for my NPS server? so that each device could trust it.
give me your solution please.

thank you
I have three TP-Link EAP245 access points managed by an EAP Controller. The speed on any of those three APs is very slow in compare to the wired Ethernet speed (internet). Measured wired speed was 495 Mbps down, and 113 Mbps up, but the Wi-Fi connections are between 7Mbps and 19Mbps from laptop or phones. There are 2.4 Ghz and 5Ghz radios enabled, and one SSID.

Are there some EAP controller or EAP245 settings that I could tweak to get this going?
I have a wireless envorment with:

Server 2012 R2 running the NPS service for RADIUS authentication to the AD
Ubiquiti UniFi APs that are set to forward auth to the RADIUS NPS server

Now I have that setup, and it works, and authenticates the users AD login, and connects to the network just fine, the issue I have, comes after that, when the user is not authenticated through the single sign on through RADIUS for the WatchGuard firewall. I have followed what little information WatchGuard has on this, but most of their information points to MSDN pages, that get me no where.  I understand that the WatchGuard needs to receive accounting packets with information from the NPS server, but it doesn't seem to be getting them, as the firewall still tries to route users to authenticate through the web portal.

Not sure where to go from here in order tell which system to send to what and where, and how.
I didn't want to hijack a thread so I created a new one. Here is a link to the original thread: https://www.experts-exchange.com/questions/26724470/Sonicwall-WLAN-to-WLAN-Printing.html

I have a SOHO wireless-N
I have WLAN to WLAN open any any any.
I followed the solutions from the other thread with no luck.
Here is the kicker, this setup worked for over a year with no problems.
We assigned 4 ShoreTel phones static IP's and instantly our wireless to wireless printing stopped working.
We have it set up to use TCP/IP printing. The printers don't show up when you go to setup a new printer.
When you run the TCP/IP method it finds the printer and selects the right drivers.
When you send a test print it starts the print job and then after printing about 1/8th of the page it stops and says print job failed.
It will then endlessly try to print the same test print until you cancel the print job.
I have hard reset the printers, I tried giving them static IP's. I called the manufactures etc.
When you connect your laptop to the LAN it works perfectly. Wireless it has an error every time.
It has to be something with the sonicwall. I just don't know enough to figure it out.
How to increase speed on a Wi-Fi router.   brand new netgear 1750 ac.  ISP speed 200Mbps.  
I'm getting close to that bypassing Wi-Fi router on direct cable.   with Wi-Fi router I'm only getting about 40Mbps.
tested with different devices.  used speedtest. net and fast. com.   same results.
also what's routerPIN?  I disabled it.   not sure what it is.
please advice.   thank you!
We currently have a WLC 5508 with a 2nd for High Availability. It is managing the following models:
We are considering adding the following models:

The questions are:
1. What firmware version do we need to upgrade to, to handle the proposed new models?
2. Which, if any, of the existing models will not be compatible with the new firmware version?
3. From the point of view of licensing, we don't need to have separate licenses for the HA, do we?

Thank you
