A very strange thing happened and wanted EE advice.  We have android phones and a iphone phones.   We are setting up some computers and its wifi router in an office.  In order to detect the best signal possible, we used an apps that would detect a wifis' router signal connection and see speed or fluctuation, etc. so we can discover the perfect spot for all devices.

For some reason the android phone had better reach to a wifi router and the iphone super less.  For example, the apps would display 121 mbps and the android phone and in the iphone would detect 23 or 50 mbps - placing both phones next to each other, inches away the wifi.  

Please advice on possible cause.

Thank you in advance.

New to Aurba Clear Pass.  Where can I find training for Aruba Clear Pass for a Aurba controller.
Ubiquiti USG will not hard reset.

I have tried using a paper clip but it does'nt seem to make any difference.
Experts - have what should be a fairly simple setup, comprising an HP 1920S switch - a Ubiquiti Access Point - and a TZ-400 Sonicwall. Trying to get public/guest WiFi running on VLAN-100, but users not pulling an IP address. Works fine on the Private WiFi network, running on default VLAN-1.

I have this near same setup working at other locations I've done so far - with the only difference between this non-working site and the working sites, is the switch in this non-working site is an HP 1920S switch - whereas other sites have rebranded Aruba switches installed that support CLI.

I've worked with Sonicwall support earlier today and they're not seeing the guest wifi DHCP request hitting the Sonicwall X0:100 interface when a user attempts to connect to the public wifi. They've confirmed the configuration is correct on the Sonicwall.  SHould be OK as it's basically a mirror configuration from other sites that are working.

So this is what I have so far:

**DHCP**   Managed by Sonicwall

DHCP assignment for private internal/wifi office 10.10.x.x and is working,
DHCP assignment for public WiFi is 172.16.1.x and is not working.

** VLAN Info **

Private WiFi and internal office traffic all running on default VLAN-1
Public WiFi is configured to run on VLAN-100.

** Switch Info **

Port #1 is the Sonicwall
Port #2 is the Ubiquity Access Point

Sonicwall support thinks it's an issue upstream, most likely the 1920S switch.  The 1920S only allows GUI. …

Hi everyone, I have a bit of a challenge to setup a streaming task and hope I could get some ideas and suggestions from the community.

I try to make a streaming video that runs 24/7 and wonder if anyone has some tips to me for both hardware and software.
My company has donated a piano that will be on a public spot. Now I have the tasks to setup a live stream that is accessible on a website 24/7.
The area has WiFi that we can use. So I try to come up with the best equipment and method to make this happen.

It has to be a 360 Video stream that is broadcasted to a website that is made with wordpress.

Does anyone have some ideas on this, of course I cant pay for a expensive cloud service. So my originally thought was to stream it to YouTube (of alternatives) and than embed this into the website. However, I do not find any good explanation, which surprises me since there are so many people that broadcast on webcams all the time.
I have the added issue that I cant connect Ethernet, it need to be standalone wifi so that i do not need a computer in the piano.

The idea is of course that web viewers can see the person playing the upright piano and they can also see 360 degree around so see the people watching.

Any guidance in terms of setup options and best camera for the job, would be very much welcome. I cant afford to make mistakes because the budget is very tight.

I have 2x 8500 WLC’s in HA SSO active-standby. The primary unit is faulty and failed over to the secondary unit which is HA-SKU. I have received a RMA for faulty unit and want to put it back into the SSO.


 In this case the new primary unit does not need license because once it is in the SSO it will inherit the licences again from the secondary unit is this correct.
I have Aruba Wireless Controller and HP Procurve core switch that connected and working with 4 different SSID. Each SSID setup with each VLAN. I have an issue connecting these two when I added new SSID with new vlan. For example, new vlan 88 with / 24 on hp switch, and /24 with vlan 88 on Aruba controller. I can't ping each other.
Other VLAN can ping each other just fine and these two devices connected directly.  What could that be wrong?
I have a wireless guest network and I'd like to test to make sure that it cannot get into my internal network. Excluding ping sweep utility, what other tools can I use to do some sort of penetration testing? Thanks

Some friends are purchasing a portable auction system running on a few laptops. This system is being purchased from scratch, so the technology on the laptops and networking hardware is open for debate as well.

Since the system will be portable and each auction location will have different "levels of local WiFi interference", I want a cost-effective wireless system which will "blow a hole in the atmosphere" wherever they will be for each auction. Coverage shouldn't need to be more than 3-4 acres (max) but a single auction may have a house, barn and steel building which would need coverage on the inside as items are being sold.

As a result, I'm wondering:
  • Are there technologies we should focus on (or stay away from)?
  • Is there hardware we should focus on (or stay away from)?
  • Are there brand(s) we should consider (or stay away from)?
  • Are there antenna(s) we should invest in (I realize this may dictate brand(s))?

I would rather not use WiFi boosters / amplifiers but they may occasionally be in basements, barns, steel buildings, etcetera. I would also rather keep it as open as possible (i.e. interchangeable antennas as needs arise (if special antennas end up being part of the solution). I've had experience with Cisco, Ruckus and your standard everyday brands like Linksys, NetGear, etcetera but am brand agnostic, as long as it is cost-effective, reliable and the coverage is what it needs to be.

Hi, all

I have a cisco WLC 3504, I need install AP Adder License, of course, I know how to install it, just choose the Management>Software Activation>Commands, then click install license.
I could do it in cisco WLC 2504, but the most important thing, I could not find the  Software Activation>Commands in WLC 3504. as picture show.,
I try to click set count,

but nothing to do with the AP Adder License, what's wrong with WLC 3504? where is Commands?

I have a working WLC5508 which I want to replace with 2 WLC 3504 configured in HA.
I'm trying to figure out how to proceed with having the 30 AP now managed by WLC5508 move to new WLC3504. What is your suggestion ? Do I have to cope with a disruption window time ?
What about having APs survive in case of WLC3504 sudden death ? Is Flexconnect the answer to this ?

I have a WLC 3504, and I want to install 5 ap-count license, according to the Cisco Wireless Controller Configuration Guide, Release 8.5,
but I could not found 'Commands' in 'Management>Software Activation', as attach picture show.

I need assistance in diagnosing cable broadband internet issues at my Girlfriends house where she and her daughter reside.
The modem being used is a Technicolor MediaAccess TC8715D and these problems have most recently affected me also.
Today, it was connected to my laptop via wifi and stopped working almost immediately after I sent the first email.
I am one room over from the router so the distance is not a problem and should be more stable on the non-5G band but it wasn't working.
I connected via the 5G band and even though I had slightly lower signal strength according to the bars showing, and it appeared to be more stable, when the opposite should be true. Everything is now working again on the higher band, but will inevitably stop working, causing me to have to switch bands again.
We have of course restarted the router, with little positive results.
I think it's the company Spectrum that is at fault in this area but I can't confirm it.
What I would like to do is find a measurable metric that would clearly identify the problem and allow me more of a leg to stand on when it came to asking Spectrum to fix the stability issues that might exist.
Assistance is greatly appreciated.
I am looking at getting a new Wifi solution for our new building.  I have looked at Meraki, Ruckus and Arruba, Sophos and even at a Cisco controller option.
I'm having a hard time deciding which solution is best for my environment.  We have two separate buildings, but will all be one system.  Hands down, the Meraki cloud has the best analystics and displays the data the best, my opinion, but it's not the cheapest.  Going from a controller based to cloud based design makes me uneasy, as if the internet goes down, then my entire wifi is down as well.  
By far I like the Meraki dashboard and the options available in their cloud.

We will need about 50 APs for both buildings.  I'm working with a vendor that said after we move forward with the purchase, they will perform a heatmap analysis, so we know where to place them, so that's good.

Any suggestions what to look out for, or any recommendations?  
Does anyone not like Meraki or any of the others I mentioned?
What's the best WiFi Extender, Repeater, Access Point? I need to have a better signal in a back room and need a recommendation. I have Xfinity from Comcast Internet.

I am thinking about offering a paid service on my guest wifi router. Considering no one around me has internet aside from their phone which has 1 bar and it isn't 4G, I think this may be a smart idea. I know how to set up a log in self service screen using Ubiquiti hardware, however I am on a budget. My starter gear is a nighthawk AC 1900 router OR a DDWRT Linksys router.

Are their any tutorials out there on how to set up a self-service access that directs the user to a paypal or square page to pay for a set amount of time? Once I get some flow of money, I can gradually upgrade the hardware.

Anyone have any suggestions?

IF I  need to, I also have a desktop I can install a service on, once the device is connected to the wifi hotspot and it can redirect to a pay for website. I just don't know what to look for.
Hi Experts,

I'm looking for a solution for my problem.

I have a captive portal setup for users to access Internet. Users authenticate via enter account and upload image. I'm trying to upload an image by using web-view (POPUP), but it does not work on mobile (Android, iPhone). I had tested it on normal browser of laptop, it works normally.

I am not android programmers, I am web developers.
Currently migrating an old Cisco Wifi network to Ubiquiti UniFi with In-Wall accesspoints, connected to Cisco PoE switches.
On the PoE port of the In-Wall accesspoints we connect a Cisco 7911 IP phone.

Wifi/AD service account for kiosks getting logged off in the middle of the night, requiring us to log back in using AD credentials in the morning.

Is there a way to make it so that we can apply group policy to one service account to make it so that we do not have to re-authenticate every day back to AD via NPS?
I setup a 3rd Aerohive AP230 at a business location.  The Cisco switch it is connected to is configured correctly (vlans).  I loaded, reset and reloaded the correct aerohive profile.
When I am connected to wirelessnetworkA on my laptop/iphone the connection will not move to the new access point, it will either stick to the previous AP, or say connected, no internet.  If I rename the SSID to wirelessnetworkA-2 I am able to connect to the 2nd access point no problem.  

What could be the issue?
I want to share a external drive hooked to my win10 laptop with my wife's win10 laptop.  I have told by friends not to use homegroup if I can avoid it.
Any suggestions and both laptops are wireless
