Wanted to see if anyone had any knowledge regarding providing 4G LTE as a backup line for an enterprise office.
I was investigating some Cisco / Meraki options, including :

- Cisco 890 series ISR
- Meraki router + Inseego (formerly Feenet Wireless) Skyus DS

Would anyone have any info or experience with one of these as a solution for a temp situation or as a backup solution.
Appreciate in advance.

Hi all,

Few machines in the wireless infrastrucuture is showing/resolving to .When seen from wireless controller these machines are connected to wireless accesspoint and resolving to with the specific mac address of that computer. Please advise on the possible reasons for this happening and what is the solution? Kindly advise
Hi Experts,

We have 20 Open Mesh Wireless Access Points in our building serving over 250+ Clients. Everything was running fine until we added 2 new SSIDs and tagged them on VLANs. These access points are connected to Netgear POE Switches and All these switches are connected to our Netgear Core Switch which is backed by iBoss (Firewall and Filtering) and Sonicwall (As a Router).

After we added two VLANs, our wireless network has been unstable since. We cant airplay to Apple TVs, Cannot connect our wireless computers / iPads to our 2 newly created SSIDs most of the time.

I did the VLAN for the first time and could be doing something wrong on that front. I have tagged the ports where i have access points connected and the ports that connects to the core switch. On Core Switch, i have tagged the ports that connect these switches and the port that connects with the iBoss.

Please let me know if you need any additional information on this issue.
I need some help if possible.  

My school is very much behind the times, so we are in need of upgrading.

Our president wants specifically to have wireless connections (literally no wires needed to connect a laptop to the system), a very simple way to record high-quality video and audio in the classrooms, and the ability to broadcast class sessions online in real time.

Can anyone give me some suggestions on this?
Okay... Here's the situation. I have sort of inherited a system. I have a 'working' location and a new location we are creating. Horizon View 7. We use dedicated pools with static machines assigned to users. There is a mix of both Win7 and Linux (CentOS and Ubuntu and something else I can't remember). All the VM's have to autologin to a desktop with a local user. This is a requirement that can't be changed. According to users in the other location, they are able to connect to their running VM's with no issues and it connects to the running session. In testing the new environment, this doesn't work. We get the resource busy or unavailable error. On my Win7 VM that I am testing with, I have installed the console plugin. This allows me to connect directly to the VM with a user already logged in, but I'm prompted for the local user account. Connecting to the Horizon server, does not work. The VM's we started working with at the beginning of this were VM's from the other location. Now we are building from scratch.

We've had our networking guys investigate it was well and according to them, this is all connected at the switch level and nothing is being blocked. I would not rule out networking though.

Any ideas what the issue is or if what we need to do is even possible? I've been told to make this work even though it does seem like it would be easier to just allow console access.
This is one of those odd ones that I can not pintpoint and nothing makes sense. One point in an office where the networks drops throughout the day. Just one of 15 computers. It is not the wifi router because the everybody else has connectivity. It is not the ethernet because I replcaed the lan cable and switched the pc with another known good computer - which does the same.

So, if everybody else work happily on wifi and ethernet, it is (can not be) not the router or switch. I replaced the cabling and if it was the cabling, why would the wifi drop? It is not the pc, because another, good pc, does exactly the same.

So what the heck? What am I overlooking? The office is in reception with steel bars facing forward and the PC and network on the same side behind the bars. The is no obscene electronics in the office. Only a printer. I am out of ideas!

Ideas anybody?
I have at some locations cisco ap 1142. Using this link:https://www.cisco.com/c/en/us/td/docs/wireless/compatibility/matrix/compatibility-matrix.html

I see that cisco 1140 series is not listed under software version or above. Do we have to replace these access points with newer ones? We cannot upgrade the software for the controller to or above until we replace the access points? Please advise.
I manage a small legal office and have a SonicWall TZ 400 wireless that covers the current building ( 15 people on the LANand only one using wifi)
The owner of the company will be expanding into a separate building across a 30 foot Breezeway next door.
I have tested the current TZ 400 Signal and it "peters out" just outside the current office facing the new office space.
 the new office space will only have two people in it)

I cannot move the existing TZ 400 closer to the new building. ( I cannot use the AC wiring to extend the wifi)

QUESTION:  SonicWall just came out with a new "mesh" Sonic "WAVE" that are around $850 each . And it requires yearly fees but support is probably great and an integrated package may make sense.  But I don't even really know if the "Wave" is the right product.  Will a SonicWall Point that not on a ethernet lan act like a mesh ?

But it  seems like a pricey solution  and I might really need two of them ( $1700)
One to boost the TZ 400w inside the edge of the existing office and one to pick up the signal in the new building.
I would like to have a ethernet port from the  device in the new building and would also like to lower the cost (above)
Does anyone suggest the SonicPoint or Ubiquity or Meraki or even Google  Wifi mesh to accomplish this ?
Please delete this question

I have a wireless network with a bunch of wireless repeaters all from SonicWall. When I am connected to one of my repeaters I can ping the company server and it responses with no loss packets. I can browse out to the internet no issues. However when ever I try to connect to my company drive It says it can;t make the connection

What could be the issue?
I just had a looked at some at the electronics store, and found these options:

1. Netgear Aircard 785s; Mobil 4G Hotspot Netgear; usage 10 hours on battery, standby 300 hours; supported network bands 4G LTE FDD, 4G LTE TDD, 3G 850 2G 900; wifi 802.11b/g/n; 127 gram; micro-SIM (very convenient: so I can carry it in my pocket and use anywhere if I have a mobile internet with a micro-SIM)

2. Zyxel wireless router AC750

3. Zyxel indoor router LTE3301; 350 g

4. Netgear AC750

5. Netgear AC1200; 385 g (a bit too heavy)

6. Netgear N300

7. From Amazon: https://www.google.se/search?q=%22router%22+hootoo&oq=%22router%22+hootoo&gs_l=psy-ab.3...6573.6940.0.7189.

Which one should I choose? The first one seems a good option.

I received advice here at EE earlier that I should always use a travel router when using public wifi to get better protection. However, I'm not sure about the definition of travel router: is it just a wireless router or is it something special that is called travel router? The shopkeeper didn't know anything about the term travel router, only wireless router.

Most often when I use public wifi at hotels it's wifi and not wired, although it happens there is wired also.

The shopkeeper told me that the main criteria that determines the capacity and price of a wireless router are these:

Number of outlets for wired connection
Frequency (higher frequency, like 5 GHz, gives …
my cobrand wifi stop working as wireless, what cause it? how to get it working back normal? it freezed and not oworking on any other devices only computer
We support a church that uses electronic hymnals via an app on their mobile devices. During services they can have up to 500 members trying to connect to 4 Sonicpoint's with the same SSID. My question is, Is there a way for the sonicpoints or the firewall to distribute the user connections equally between the AP's?  

Right now most users can't connect and the ones that are have terrible connections (speed). Which I assume everyone is connecting to just one AP.

I thought about sectioning off the pews RF,LF,RR,LR . Then create SSID's associated to those sections. But there has to be a better way.

Thanks in advance for your help.
Hello - we are experiencing some problems with limited wireless connectivity on some laptops at our company, and we're looking for some advice.  Here's what we're working with - we have 2 buildings next to each other - each have a wireless network. Bldg A has had a WIFI network since 2008, comprised of Cisco Aironets - its a hidden SSID and is on subnet A.  Bldg B is new, and has Cisco Meraki APs which are on a brand new network backbone, and on a different subnet B.  The telecom installer who installed and configured the Cisco switch and the Meraki APs tested the WIFI connection with his Windows 10 laptop and it worked fine - in that it received a valid IP configuration via DHCP on the 2nd subnet B.  We also pulled a Windows 7 laptop out of a storage cabinet (which had not been used for a month) and it also received a valid IP config via DHCP.  Another IT guy, however, brough his laptop over from the 1st building (subnet A) and tried connecting on the WIFI in the 2nd building (subnet B) and it fails.  Says limited connectivity.  We tried "Diagnosing" his connection and a few other things like uninstalling his WIFI NIC and reinstalling it.  Also tried forgetting the old WIFI connection and setting up the WIFI connection all over again, and nothing seems to work - unless we manually code an IP address for the 2nd subnet B.  So - it does not work with DHCP, but does work manually.  But we have OTHER machines that DO work with DHCP, on the subnet B.  So - I wanted to brainstorm …

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.
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 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?
WatchGuard Case Study: NCR
WatchGuard Case Study: NCR

With business operations for thousands of customers largely depending on the internal systems they support, NCR can’t afford to waste time or money on security products that are anything less than exceptional. That’s why they chose WatchGuard.

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.
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
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 subnet using the Comcast router for DHCP.  The guest networking device would have DHCP server built in and dole out say subnet addresses.    The device would also block any traffic from going anywhere on the subnet other than the gateway out.    Does such a simple home /smb device exist?
Since the phone beeing bypass its showing that the network service as been blocked. How can i unlock the network service for free without a pc?

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)
