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.

I am testing a  Meraki for spoke site VPN. Most of these sites are very small - 10 - 20 people.
Does it help anything to have a separate WiFi vlan/subnet apart from the wired vlan/subnet?
With one /24 they'll have more than enough addresses.

Thoughts appreciated.

Hi All,

We are currently configuring a wifi solution for several hospitality suites. The Internet feed has been installed and we will be using a Watchguard Firewall with three Vlans. One for management that will host the switches and Access points. And two for connections to the outside world. One VLAN will be used to broadcast the SSID the second is for private use.

What is the best way to configure the Watchguard Firewall. I was thinking to have one interface for each vlan. IE trusted for Management, and then a seperate interface each for the other two. Or would it better to leave the trusted interface alone and configure one of the other interfaces for vlan use and put all three VLANS on this one. Or is there a better way of doing this?

Thanks for your help.

We have an SSL Certificate that will expire soon.  The current SSL Cert is issued from a Certificate Authority and it is used for Captive Portal (Guest) user access to allow guest users to login to our WiFi  using a username/password.

The current Domain name is something generic as "WIFI.DOMAIN.COM".  I have instructions on how to generate a new .csr for this appliance: https://community.arubanetworks.com/t5/Controller-less-WLANs/How-to-Create-a-Certificate-for-Instant-Captive-Portal-using/ta-p/277025

The instructions are pretty straight-forward; but, my questions are:  

1).  Will I need to create a new SSL Certificate for a new Domain Name (example: OFFICE.DOMAIN.COM) ?  or can I re-key the existing SSL Certificate and use the same domain name?


2).  What is the difference between Re-Keying the existing SSL Certificate and creating anew one?

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:

Hello,
        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?

refer to attached: the "Start Hotspot" button is greyed out even
if I launch MyPublicWifi using local administrator.  Had earlier
rebooted PC as well (a requirement for post installation).

i've also click "Automatic Hotspot Confign" button & the tab
'Set Up & start Hotspot" is greyed out too.


This software did not indicate it requires .Net Framework etc.

Don't want to use Connectify as it's not free;  actually the free
version had to be restarted every 60mins

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

           George

Key Symbol with Yellow Triangle in Task-Bar.

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?

Hello,

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 [[172.23.22.111]] 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 ?

We have multiple smaller type ISP providers in the city using microwave technologies.  Basically installing antennas on buildings and pointing to their HQ location.  Trying to figure which one to pick based on their building location, etc.

What's the max distance they can go without the hop/repeater?

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.
