Hello Experts,

I am investigating options for setting up remote cameras at our work sites.  I have a system that we purchased from a provider a few years ago, and am trying to determine if this is something that can be done cost effectively in-house.  The one part I am looking for advice on is using a 4G wireless modem and how to get it connected to a given carrier (Verizon Wireless, for example).  I have a Sierra Wireless RV50 in hand.  I am new to this process so would need to start from the beginning.  I am guessing that I would first need to contact Verizon and create a new line \ account, and get the required SIM card for that line?  If that is the case, then once I have the activated SIM card, I presume there is additional setup required on the modem?  I've reset the modem and have access to its management interface.  Additionally, once the modem is connected, and I've set up an "internal" LAN on the modem and addressed the camera(s) for connectivity, I am guessing I could use DDNS to reach the cameras remotely?  I've been told that VZW charges $500 for a static IP.  I would want to avoid that if possible.  Any \ all info on how to get the wireless modem connected and available on the internet is greatly appreciated!!

Thanks in advance,

Russ

I have an indoor bike trainer called Computrainer.  Communication protocol is old-school serial port.  Eventually, SERIAL/USB became available and is still used today however with so many newer mobile apps, it would be ideal to have some way to communicate over Bluetooth, WiFi, or ANT+.  Prices for adapters vary a bunch.  Are these solutions all viable?

We would like seek for advice for the Aruba’s firmware version convention.We will implement WiFi in our ware-house soon we found out our Aruba IAP 305 firmware version is 6.5.4.3

We want to integrated with our Air-Wave and AirWave mention that support Instant 6.5.0.0-4.3.3.3 ,Can we confirm if IAP version 6.5.4.3 is the same with 6.5.0.0-4.3.0.0? I am quite confused with Aruba’s firmware version convention.

Hi,

I have been searching for a matrix listing the security advantages and disadvantages of wi-fi vs Bluetooth vs cellular vs ethernet.  I searched for a specific technology I mostly find publications talking about the general connectivity differences using the technologies but nothing side by side like a matrix that includes all three measured against the same baseline. I tried using two different articles and list the information in a spreadsheet but the categories and the baselines used were not the same - problem. Do you know of any resource that may have this information in a matrix view that I can review.  

Thanks

Cisco Mobility Express - I have 2 - 2802E's and a load of 2702's
One I have setup as a controller works fine, now I want to setup the second 2802 as a failover controller.

Initially I flashed it with the lightweight firmware it joined then went into my ME controller and said convert to ME, now it comes up ME capable.
That one seems to sit on the setup wizard at least when I look at the console port.

The first time I gave it some time thinking it would get the config and eventually just come up as a controller but nothing.
It does show up in ME as ME capable. I went into my controller and clicked make ME Controller it just rebooted and went to the same place.
I ended up rebooting it there essentially killing the setup wizard. It seemed to work but the secondary controller kept disappearing in ME until I rebooted and then it would show up again for a while.

I reset it and flashed it as a CWAP again, worked fine.
I had ME convert it again and this time went through the wizard and gave it the same settings as my main controller, it came up and I click Make ME controller now they are fighting back any forth I'm guessing over the management IP which makes sense so I just shutdown the second one for now.

I can't find a single document regarding bringing up a secondary controller using on premise ME unit.
I found documentation using cloud based services and using full blown WLC's but nothing in regards to what I'm using.

I found a few brief mentions about …

Cisco 2802 CWAP will not join 2802 Cisco ME Controller.

Pardon me I'm not Cisco expert but we've been running 2702E's in Autonomous mode successfully for a few years so obviously ME is a step up.

I have a 2802 online and I keep ending up with "Max retransmission count exceeded, going back to DISCOVER mode." when it tries to Join the controller.
This is first AP I'm trying to join and I don't have another one to test with right now. I need this one online so I can pull another offline and get it online.
Devices are on the same LAN and even switch for testing.

I changed the retransmit count and interval on the ME controller shown here:
(Cisco Controller) >show ap retransmit all

Global control packet retransmit interval: 5

Global control packet retransmit count: 8

AP Name             Retransmit Interval  Retransmit count
------------------  -------------------  -------------------
TX-2802-1                5                8


However this is what I end up with when the CWAP tries to join:

(Cisco Controller) >show ap retransmit all

Global control packet retransmit interval: 5

Global control packet retransmit count: 8

AP Name             Retransmit Interval  Retransmit count
------------------  -------------------  -------------------
MX-2802-1                5                8
AP00A3.8E90.F1DA         3 (default)      5 (WLC default),5 (AP default)
(The second one obviously being the one I want  to join)

I have an issue where a HP ProBook 4540s cant see the wireless network. It picks up other nearby networks and all other devices can see the wireless network and connect. The network is not hidden and the laptop has the most up to date drivers. The laptop used to see and connect to the wireless network and nothing has changed in the setup.

Hello,

I have a device, camera that connects to wifi and transmits the video via wifi. How can I read this video buffer from this device using Delphi Desktop application and display the video in this desktop app? Via ethernet LAN connection. Using TCP read buffer? But how to read the right buffer exactly from this particular device? Please show me some code.

Imagine this scenario. I have a video surveillance  camera transmitting video via wifi in country A and I want to see the video in country B. Via LAN.

The goal is to get rid of different corporate SSID and just have one Company authentication.   User roles determine what networks and resources they can access.

What's the best way to do this?  Radius, RSA Radius, NPS, LDAP, DaaS?

There's request to set up a dedicated Internet Wifi hotspot
that will be used to connect up IoT : one such item in mind
is power meter.

We are not a financial/banking/healthcare organization but
still need to adhere to government guideline on cybersecurity.

I can only think of the following if this is to be granted:

a) restrict it to IoTs only ie corporate laptops/PCs/user devices
    can't connect to it : so what kind of mechanisms out there
    can stop corporate PCs/laptops and user BYODs from
    connecting?

b) we'll make the SSID unscannable

c) as many IoTs have been known to be compromised, such
    as Mirai, botnets attacks, how shall we mitigate these as
    the IoT is exposed to risks from Internet.
 
d) any other mitigations?

Hello,

I need a line added in the VBScript that will delay setting environment variables for 10 seconds or so.  It appears it doesn't work well when using Wifi.  There is sometype of delay.  What would be nice is to verify Active Directory is available then run the script.  That might be the most helpful.  If doing this in Powershell would be better, let me know.

Thanks!

Set objShell = CreateObject("WScript.Shell")
Set objUserEnv = objShell.Environment("USER")
Set objADSysInfo = CreateObject("ADSystemInfo")
Set objUser = GetObject("LDAP://" & objADSysInfo.UserName)

' This will create the variable %mail% for the primary mail address
objUserEnv("MAIL") = objUser.mail
' This will create the variable %FirstName% for First Name of User
objUserEnv("FirstName") = objUser.givenName
' This will create the variable %LastName% for the surname of User
objUserEnv("LastName") = objUser.sn

As we know, AP needs to get ip address first when it wants join WLC. so its dhcp server is very important. My question is if the AP is assigned with static ip address, do you think the dhcp server is still very important? I mean if the AP needs other function from the dhcp server? thank you

I setup a new 2016 server to be our dhcp wifi server. I went through all the steps to export the dhcp file of the 2008 r2 server and then did the import to the 2016.
All seemed to be ok and I see all of the reservations and scope on the new server and the ipv4 and 6 both have green check marks but when I run the authorize managed servers, it says The DHCP server could not contact Active Directory.. I get this when I run Netsh dhcp show server..

Do I need to make any other changes?

Windows 7computer is having WIFI problems where it will connect to networks at hotels, for example, but will say "you may need to visit a login page to gain access to the Internet".  This happens at  multiple hotspot locations, where it "connect" to the network, but shows "no Internet". IF the user connect to their Verizon hotspot on theior phone, however, they can get out to the Internet without an issue.  On the capture portal login page topic, when she pens a brower to wait for the page to show up, othing appears - just says "no connection".  Is this something that is Windows 7 related, or most likely browser-related?  Thanks

Connecting my WiFi Xerox 6022 Laser Jet (Macbook)

My printer stopped working, and before I realized the router was blinking, I deleted the Printer.

Now I have reconnected it with the WPS button, but I can not find how to add the printer to my MacBook, so I can use it.

What am I missing?

Thanks.

What are some good Wi-Fi hotspots that have unlimited internet access?

I need a Wi-Fi hotspot (separate from my cell phone) that I can use on my Windows 10 laptop anytime I am someplace that doesn't have Wi-Fi access available that I can use.

What are some good hotspots and plans that offer unlimited access?

understand wireless Network setup.



I would like to understand in the Nutshell  how comapnies setup Wirless network

I believe you Need a wireless controller, Wireless Controller will be connected to you existng Wired LAN switches, if you plan to give access from Wireless Network to Wired and vice-versa.
 

Then comes the Access Point part, I believe you need to  configure Access points to connect wirelessly to the Wireless Controller.

If I am missing any step, please correct me.

Tahnk you

We have one laptop that every time it turns on the wireless icon is gone.  I have to run the troubleshooter to fix it.  I've watched two videos on how to fix it by making sure the Network setting is turned on and by restarting the Windows Explorer process.  Neither work.

We have 2 x Aruba 7030 hardware appliance controllers that we want to use as local controllers for our Aruba Wireless system.  Another administrator setup:

2 x Virtual Master Controllers.
2 x hardware 7030 controllers.
1 x specific VLan IP Subnet where there Hardware local controllers reside on with the Wireless Access Points.

Both Aruba hardware appliances are in 'Standalone' mode. We wish to change the mode from 'standalone' to 'local'.

My question is how can I change the mode of the hardware controllers from 'Standalone' mode to 'Local' mode?  I hope I do not need to reset the controllers to factory default settings.  

I have found a web site ( https://community.arubanetworks.com/t5/Wireless-Access/change-controller-role-from-standalone-to-local/td-p/279521 ) that states

"... You should only have to add it as a local controller to the master via cli
 
>masterip <ipaddr> ipsec <key>  ..."

Since, I have never done this before I just want to make sure that I understand what needs to be done.  Hopefully, I can communicate with someone that has actually done this before.    My understanding from the above web site is:

1.  You can change the mode of a controller without re-setting it to factory default settings.

2.  Login to the hardware local controller and from the C.L.I. >masterip <IPaddress> ipsec <preshared key><enter>

3.   The IP address that must be entered is of the Master Mobility controller; but, what if you have 2 master mobility …
