Wireless Networking





Wireless networking is anything related to the transfer of data between two (or more) devices without the use of a physical connection, ranging from getting advice on a new Bluetooth headset to configuring sophisticated enterprise level networks.


refer to above link which I've followed but when my PC connects to
the Vonets  SSID (with a good four bars signal), it says "No Internet"
: will attach screen.   What did I miss?

Have set it to "Bridge mode" as recommended by previous expert.

I ever set this same device up successfully previously but someone
in the house pressed the 'Reset' button & this time round I can't
get it right\

Manual is here:
I wanted my PC to act as hotspot, eg: by installing Connectify
or MyPublicWifi: the PC connects to a wired LAN but wanted
this PC to act as AP so that other devices could connect to it
& surf the Net.

I'm not allowed to install 3rd party softwares like Connectify
on office PC but can install a driver for a USB/dongle-like
device to make the PC a hotspot & thereafter the USB port
will disabled files transfer (in & out) but the USB could still
provide power supply & charge my mobile phones.

Anyone can point me to an Amazon or eBay link of one such
USB adapter/dongle??

I'm not looking for a device like one below as device below
connects to a broadband router  or  possibly an RJ45 port
of an ethernet switch but a dongle that connects to a PC:

        I have a Asus RT-Acrh13 router that I am trying to tether to a Verizon Hotspot. The Hotspot has USB 3.0 so there no USB version conflicts should be causing this.

 What happens is this:
1:  I power on the Asus and let it get to ready.
2:  I plug in a ethernet cord to the 4th port on the system and connect it to my laptop.
3:  I then connect the Hotspot to the Asus. the Hotspot detects that a device has connected
4:  I start the Quick setup (for some reason I can't get to the setting otherwise ) and set the device as USB Modem and finish the quick setup.
5: I then go to the network map and see that the Hotspot is there but I have no internet connection.

Unplugging and reconnecting the Hotspot shows that it is dis/connected on the hotspot and on the router but nothing happens. I can set the Hotspot to USB and Wifi but that still does not let the USB connection work. Thinking that it could be the Hotspot that is the problem I tried my cell and it was the same result except that it says that the cable is unplugged ( which it is but that is not the point ) I did some research on it and as luck has it I have a phone that is just incompatible with this router: a Samsung S7. I borrowed a 10S from a co-worker and hers "worked" as in it gets a IP but I still can't get online from our systems.. I updated firmware and tried 4 different cables. the results are t he same. Any tips on this?
I'm practicing a bit of pen testing against my WIFI network.  I am trying to see if I can uncover the hidden SSID using Aircrack-NG via Kali-Linux.  I've loaded Aircrack-NG, put my wlan0 into monitor mode then ran an airodump-ng to see if it picked up any channels.  It doesn't, nor is it picking up any other wireless channels around me.  Can anyone that is familiar with this program tell me what it is I am doing wrong here?
Hello and Good Afternoon Everyone,

          Recently, I purchased an AT&T WiFi extender that broadcasts on both, 2.4GHz and 5 GHz frequencies in order to secure a wireless connection on the other side of the house so my friend can access the internet.   While he is able to load web pages and playback videos on YouTube, the signal strength is very low, about 1 to 2 bars.  My concern is that the low signal strength will eventually drop off to nothing, thus, leaving my friend without any internet access.  Given this situation, what would everyone recommend with respect to boosting or increasing the wireless signal strength?  Will another WiFi extender be in order to place on the other side of the wall where my friend lives?

           Any feedback that can be given here will be greatly appreciated.

          Thank you

I have found out today that on my notebook the wifi connection is not working.
I am using an EAP-Auth with NPS on Windows Server 2016.
Sometimes it happens because of using other wifi areas that I have to reset the network and re-intialize winsock int ip.

None of all worked today, I recognized a new icon in task bar, attached you have a pic of it.
No toolbar is shown.
The only article I found pointed into outdated credentials.
So I changed my passwords, exit and re-entered the domain, right now I am working with a local admin account inside a workgroup.
The icon is still there.

I have not found any process or something strange on the system.
Windows license is digitally equipped.
Bitlocker is up and running.

Do you know this icon? Do you know that it means?
Hope you can help, I am getting a little paranoid and running malware scans...

Thanks in advance.

I'm looking for help determining the best solution for our environment for wireless.  We currently have an 8 year old Cisco 5508 Wireless LAN Controller, and 94 Aironet access points split between really 3 buildings.  We are due for a refresh and have a bid in from a vendor who is recommending using Meraki WiFi6 with licensed cloud controller, and did not suggest using a locally managed WLC with Aironet APs.

We are a school district and need feedback as this is a vendor I have not dealt with before so I have trust issues.  I like the idea of not having a physical piece of hardware on site that if fails my wireless is down, but I don't like paying costly yearly licensing fees either.  Any insight?

I am looking for help regarding settings on my NetScreen SSG5 firewall.  Two days ago I updated my internet from a legacy Time Warner plan to a new plan from Spectrum.  This involved swapping out my model.  The old Time Warner product was a combination modem/wifi router while with Spectrum I was given two devices - a modem and a separate wifi router. I have two networks in my home - one is for personal use and for our streaming TVs.  The other is a work network I use for my home office and my wife's PC.  When I made the switch the personal use network worked fine but nothing sitting behind the SSG5 could connect to the internet. Attempting to ping anything public, including google, resulted in timed out errors.  I suspect that either a port needs to be opened in the new wifi router or an IP setting(s) needs to be changed on the SSG5.

I called Spectrum tech support and logged into the SSG5 and looked at all of the settings.  It was correctly sensing the new public IP address.  There was a problem with respect to the DNS settings.  The IP address listed as the primary DNS address was actually the secondary address and the one listed for the secondary was incorrect.  I changed these to the correct values but the problem still remains.

I realize you probably need more info than this to figure the problem out.  Please let me know what you need.

One idea I had was to unplug the SSG5 for a minute and replug i in, to sort of reboot it.  I have not done any …
Hi Experts,

I know that that there are WiFi Extender products, but my question is not for these products, but rather, how to Extend my WiFi?

My apartment is close to 1200SQFT and used to have Bell Canada Internet Residential, which came  with 5 "Bell Pods" with a "Bell 3000" Router/Modem combo and my WiFi was good.

However, as I run a Web Design business from home, for one project I needed to get Static IP which was not offered through Bell Residential, so I upgraded to Bell Business. It comes with "Bell 2000" instead, but much higher down/upload speed 300/900 mbps. They don't provide the Bell Pods for business, saying that they only provide the bare minimum, and I need to build it up, which makes sense.

My networking aren't that great, but I'm not afraid of Router settings neither. So, my question is how can I extend my WiFi in economical sense. A few years ago, I had Rogers that also provided a Modem/Router combo, but I did add my own router and disable Rogers router feature, so I am able to do that as well if the Bell 2000 allows it.

My Bell is Fiber and the Fiber runs through the room with no WiFi, so I am also wonderig if I can take advantage of that by placing a device there, and then a Fiber extension.?However, currently my router in my office with a lots of wired devices.

I also came across https://www.youtube.com/watch?v=ie4imVwn9vk, which talks about Samsung SmartThings and I like that signal bounces pod to pod and finds the less congested route. …
Hello and Good Morning Everyone,

         Recently, I ordered and set up a WiFi extender provided by AT&T.  I did notice that both, the 2.4 GHz and 5 GHz lights are a steady green which is the way it is supposed to be.  Just out of technical curiosity, I am wondering why the WiFi extender needs to simultaneously broadcast on both frequencies as opposed to just one.  

          Any shared views or thoughts regarding this question will be appreciated.

          Thank you

DHCP  for Wired and Wireless Devices

I would like to have an Expert explain the path Wired and Wireless devices take to get IP address from DHCP  

I put a diagram below, it might not be the right path that devices take to get IP address, but it can be corrected by an Expert.

Thank you

Hi Experts,

after DHCP migration, all WIFI clients do not get any IP.
But over LAN it works.

Here is the error:

PTR record registration for IPv4 address [[]] and FQDN PC1-NB001.wittur.com failed with error 9005 (DNS operation refused.

Open in new window

The DHCP is not on DC.
It is installed on another server.

Any ideas ?
I picked up a couple of the new Linksys Business APs that allow VLAN Tagging and I am having fits getting the VLANS on the switch configured properly to get these APs to work. There are currently 3 VLANS on the switch:

1: Management, ports 1-28, port 1 goes to SonicWall
2: Guest, ports 29-34, port 29 goes to SonicWall
3: Printers, ports 35-44, port 35 goes to SonicWall

Each port on the SonicWall is a different network and does the rules between networks. It is also the DHCP for each network. So... what I was trying to do was put these APs on the Guest network and if I were to tag a specific SSID with VLAN 3 it would give the clients on that SSID access to printers.

So what D-Link told me to do was to tag port 35 and share it with the Guest VLAN. So when a client on that specific SSID (tagged with VLAN 3) came in to VLAN 2 it would immediately pass the packet to VLAN 3 and in turn give it access to printers.

When I did that the management VLAN could no longer avvess printer. What a mess. It seemed so simple. Any ideas on what I am missing?
Does someone have a policy statement or can direct me to one for Wifi.  My company has internal wi fit, staff that travels so airports, starbucks, bars (!).  What should be telling them.  So far, we have said avoid any wifi with no password protection is a no. I rush off the plane and check my email and before you know it, I have been on the airport wi fi (no password) for an hour.  Executives pay for access on the plane, is that safe?

I recently purchased a Netgear Nighthawk Wifi 6 router and Wifi 6 mesh extender.  My ISP provides a cable modem and router together. The modem/router from my ISP has a wifi connection as well as LAN.  I have heard when you add access points to a network, the network speed gets cut in half.  My first question is, does that happen on a mesh network? Second question is, if I am getting all my connections from my Nighthawk, does the wireless on the modem/router cause the speed to get cut in half as my connection from my ISP modem/router to my Nighhawk is connected through LAN? Another words, should the wireless signal be cut OFF on the cable/router?
The client notebooks (Windows 10) of our company can only access the Internet using a proxy in our security infrastructure. When they are connected to an external (W)LAN, they use Citrix Netscaler VPN for connecting internal services and our secure proxy. That perfectly works.

If they try to access an external WLAN with a captive portal web page though (for example in a hotel), they have to disable the proxy first, so that the captive portal can be loaded.

If users are allowed to remove the proxy, users easily find out, that they can access the web bypassing our secure proxy.

Do you have any idea how to connect to a WLAN with a captive portal when a company proxy is mandantory? Is there maybe a WLAN-connection-client with an internal browser and individual proxy settings?

Best regards!
On this new gig - the predecessors put one AP in the ceiling for 1/4 of the building which is top
execs. It looks like there are about 80 devices attached to it and 2.4Ghz is said to be 46% utilized and the complaints are off the chain. I wish to maximize performance and money's no object for adding more APs if I need to. How do I optimize the Merakis for peak performance with less regard for coverage radius?
Went on a call to a new client today, who has been having issues with their network.  They have a DSL modem with WiFi on channel 1 (Since disabled) cascading to a TP-LINK Archer c5400 (Upgraded firmware today).  They are working on getting the PPPoE (Centurylink DSL connection) so we can bridge the DSL modem and set the router up properly.  Some devices hardwired and wireless will not function because they are getting a DHCP address from the DSL modem.  I can log into the DSL modem on those computers.  Is this a malfunction in the TP-Link (It only happens less than 10% of the time and very random on devices)?  I have had very bad experiences with TP-Link switches, are their routers any better?  The owner said the problems have always been existant and the old IT company (who installed it), could never get it working 100%.  I am recommending replacement of router, but wanted to hear thoughts on this subject.  The client will be ordering their own new router, and won't have until Monday.  This should be a non-issue once the modem is bridged.

If I release the DHCP enough times, it will go back to the correct DHCP server of the router and start working properly.  The DSL modem is not accessible by devices connected when getting the working IP address.
I purchased a Nighthawk AX8 to replace my Orbi 5 system. My goal was to start adding Wifi 6 equipment as it is available.  Although the Nighthawk has pretty good coverage, my house is about 3,000 sq ft and my office is in the opposite side of the house, 3 floors up.  I can still get a 5ghz connection, but it is very weak.  I am considering purchasing a Nighthawk EAX80 Range Extender that also has Wifi 6 (Mesh Network).  

I have two questions.
  1. I assume I will not have to have a hard wire on the extender
  • Since it is not an access point (its a mesh network), I should not lose bandwidth (splitting bandwidth in 1/2)?

My goal is to have a full 5ghz connection throughout the house.  At this time, I am not considering running more wire in the house. I would like to keeps it mostly wireless.
How can I disable "all INTERNET access, including WIFI"
on the below #4 via gpedit.msc or something else ?

   ** Operating System = Windows 10 Pro
   ** User = 15 year old child
   ** Domain = NO

  1. I login as me since I am a "Local Admin"
  2. All "all INTERNET access, including WIFI"
     fails since I don't need it to work
  3. my 1 year old logs in with NO "Local Admin" rights
  4. All "all INTERNET access, including WIFI" fails
We have several Lenovo laptops, mostly Yogas.  All are having the same issue.  They connect fine to our (and other) wifi network, but the drop after a few minutes.  We've updated the drivers, turned off power saving, and it still happens.  We've tried limiting the dual band to a single frequency, no luck.  Anyone else have this problem.  We have a variety of other laptops by other manufacturers that work fine.  We like the Lenovos better other than this problem.
I wish to add an email account to the email client on my iPhone 7. My  email address is s…….@eircom.net (an Irish  provider, formerly Eircom.ie and now  Eir.ie)
 I have .’chatted’ online with Eir.ie  technical support. They told   me I have to get the details about outgoing and incoming servers from my own internet supplier, which is not eir.ie  but Lycamobile.ie. When I contacted Lycamobile support the didn’t seem to know what I was talking about (and probably I don’t) when I asked them about the  outgoing server I needed from them.
I rarely use Lycamobile for my internet, depending on the local WIFI in my office or home. I always thought that my email works with any  WiFi connection even if my supplier (Lycamobile)  is out of range or down, or if I have clicked on ‘forget this network and enabled a local WiFi). I’m probably wrong.
Anyway I have not succeeded in getting adding the account to my iPhone)
SDN and SD WAN and SD Access and DNA Center

I have read about SDN and SD WAN.  if I understand They both are based on Centralized Control Plane.

So if I have  the Traditional Local Area Network  made up of Access/Distribution/Core   Layers,  and when I want to Implement SDN Technology , at what layer should I integrate SDN.
in other words if there is a hardware on which SDN is installed on, where should that hardware be located ?

SD WAN is WAN Technology , if I want to implement that technology  where should  I put the hardware that holds the SD WAN software.

if you can briefly give the    difference between SDN , SD-Access, SD WAN, DNA Center that might also help clear up the Terminology confusion.

THank you
Hi all,

I have wifi at work which and it is for guest users. it works fine with laptops and other devices. The only App on the mobile phone that is very slow is Whatsup.

I tested with our new App for Microsoft Teams and it works fine. So the issue here is only Whatsup App. My question is:

How can I make this Whatsup App work faster?

Can you help?
A friend of mine recently recommended I get an access point in addition to the router I have.  What access point should I buy?  I have an Apple AirPort acting as my router/access point for about 30 wireless devices in the house.

My plan is to have my router hard wired to my desktop and smart tv, then an access point setup to serve the rest of the devices that use wireless (Nest, Baby monitoring cameras, cell phones, ipads, etc).

When you recommend an access point should I make the Apple AirPort the main router or have the new recommendation be the router and turn the AirPort into the access point?

Thank you.
