Our trainers experience bad internet connections at some schools. I would like to provide them with a "mobile" (as in take it on the train) version of our platform running on a laptop, which the students can connect to directly via a private WiFi network. "The internet in a suitcase".

I have been troubleshooting some enterprise wireless issues with Intel Wifi cards and Meru Virtual Cell APs (AMA!). Either by changing some Intel Driver settings, or by resetting DNS/WINS stacks (prompted by "Configuration Change" events on wifi driver causing dro ...
I have recently started working with a museum (UK) who's 1-year-old Cisco wifi setup has been experiencing connectivity issues from day 1.
Essentially a significant proportion of devices (both in-house and personal) are unable to connect to wifi - user selects an SSID, enters correct password, authenticates and instantly the connection is dropped. This effects some laptops, phones and tablets, bu ...

I'm using Windows Mobile Hotspot on my laptop to share its Internet connection with other devices.
It sets up a DHCP service, using 192.168.137.1 as the gateway address, and leasing out addresses on 192.168.137.xxx network.
How can I change these settings? Suppose I want my gateway address to be 192.168.13.37, and the users of the Mobile Hotspot to be assigned 192.168.13.xxx addresses.
We have differents wifi clients Some of them on Android/Apple phones, others on PC Windows. Wifi is authenticated by NPS and we have a DHCP in wwindows server.

I'm trying to find the keyword which proves/states that an USB wifi adapter can act as an 802.11ac access-point.
So far I have tried 3x 802.11ac usb adapters and the internal card on a Pi4. All have only been able to create 802.11n networks. At this stage I do not believe it is a configuration/driver issue as all USB adapters have been tested using ubuntu (Pi4) and Win10 on an x86_64 device with ...
If the issue happens, it happens at 10am, for about 1minute between onset and return to stability. It does not happen every day. During the minute, pings go through the roof and packets start to drop, then the pings settle down and packets stop dropping, everything is fine again. This occurs on our wifi to the point that wifi users effectively loose internet, signs of the issue are visible on the wired ...
Here is my networking setup:
The system is running Proxmox (Debian-based) so it has a bunch of VMs.
The default bridge of the system is vmbr0, connected via ethernet to a network with the 192.168.86.0/24 IP range
I wanted to create a new bridge (vmbr1) that bridges the current VM to another network with the 192.168.1.0/24 IP range, via wifi

We use TCPDump on an RPI to capture WiFi signals from nearby devices as a means to get an estimate of number of people.
We have notice the on "normal" days the numbers are reasonably accurate but for a couple of times where we had much larger numbers of people the counted devices are no where close to what should be counted.
I have read a couple of articles saying the default buffer size may be to l ...

I am trying to connect a Bresser 5-in-1 Weather Station to a workplace's wifi network, which uses RADIUS WPA2 Enterprise security. From a laptop or smartphone I can connect to the network and then enter my credentials (user name and password) to get on the Internet, but this won't work with the Weather Station since it lacks a web browser. The only configuration that I can perform on it is through a ded ...
I am working at a site where DECT is implemented on Mobile Devices, and I am wondering if it is possible to setup a TCP/IP network using DECT as the data transmission layer.
i'm using TP-Link MR3220v2 with its Openwrt firmware. what I would like to do should be simple, but I am not succeeding. i have 3 devices in two different subnets and i would enable communication through each devices (i don't know if i can say that i would like "bridge" the 2 subnets). this is the devices list:

I am currently setting up new laptops in our system. All users have a specific group in AD with different credentials for WiFi and login.
The issue is that in order to connect to the domain controller the users have to connect to wifi before logging in (on the lockscreen), unless their credentials are cached.
My goal now is, that every user has to use their own WiFi credentials to access the WiFi. I ...
It's probably possible to go to any restaurant/cafe/bus with public Wi-Fi Hotspot and flood it with DHCP DISCOVER / REQUEST packets. If this network is created by a router that works as a DHCP server, than such attack should lead to IP starvation, right?
Is there a way to prevent such attacks?
I'm talking about the wireless networks only. The place where every client use the same shared medium and i ...
My company recently purchased a few Mikrotik hAP Mini. These units are used for Site to Site VPN. The first unit I setup manually worked flawlessly. I then exported the configuration to the second, third and fourth units.
On these 3 units, when my Pixel 3a is connected, it receive an IP address, proclaming "no internet connection" and after one second it disconnect and reconnect to the WiFi over ...
We're setting up RADIUS authentication for wireless network connections through a Windows Server 2012 R2 (NPS).
We have to allow both domain computers (registered in Active directory) and non-domain devices, typically Android smartphones.
Following this official documentation, the behaviour is as excepted and working fine for domain computers.

So we have EAP-PEAP over MSCHAP working. What I'd like to do is have a MAC Address check, for the purpose of making sure people aren't putting their credentials into random devices. I know SCEP would be the better option here, but this is where we're at right now.
So I noticed that the mac address is passed to FreeRadius under

I have major issues with a device (Ubuntu 20.04 installed) in a warehouse with multiple access points. I am frequently losing the SSH connection. Investigating the matter, I found out that I lose connection whenever the device roams to a different AP (same SSID). Digging deeper, I found out that the SSH connection is only killed when the device roams to an AP with a different OUI (lets say YY:YY:YY indi ...
