networking – WiFi is connected but still cannot access internet

I have a fresh install of the current version of antiX (19.3)

The WiFi appears to be working, but I can’t connect to anything.

The WiFi wasn’t working after the install, so to start the WiFi I did this:

  1. I first unblocked the wifi:

rfkill unblock 0
2. I used “ceni” to set up the connnection (all I did was select the wifi option, then selected my wifi’s name and then entered the password)

Two small graphical monitors then appeared on the desktop (“wlan0” up and “wlan0” down) which seem to show ingoing and outgoing packets – that is why I think the connection is working.

However I cannot connect to anything (in a browser or using ssh). I also tried to set up the connection using Connman, but that didn’t seem to help.

What could be wrong?

I have included some diagnostic output below.

radius – How to protect against MAC spoofing in WiFi network?

I have this scenario:
I want to create a WiFi network for a hotel that the customers should pay to gain access to the internet.
I tried Captive portal, but captive portal is very vulnerable against MAC spoofing.
So I tried wpa2-enterprise without Captive Portal. But NAS(Access Point) in wpa2-enterprise doesn’t enforce any rule and each user had unlimited access.
Then finally I tried both together but after first authentication in wpa2-enterprise each user was able to change his/her MAC address to a any other user.
I’m using PFsense as RADIUS server and Mikrotik RB433 for Hotspot(Captive Portal) and wireless AP.

  • Is there any way to prevent users from impersonating to an authenticated user in WiFi network with Captive Portal?

  • Is there a reason that NAS in wpa2-enterprise doesn’t enforce any policy or something is wrong in my configuration?
    These are the policies that PFsense generated in users file:

"amir" Cleartext-Password := "amir", Simultaneous-Use := "1"

    Framed-IP-Address = 10.1.3.85,
    Framed-IP-Netmask = 255.255.255.0,
    WISPr-Bandwidth-Max-Up := 50000,
    WISPr-Bandwidth-Max-Down := 50000,
    WISPr-Redirection-URL := http://www.google.com,
    pfSense-Max-Total-Octets := 10485760,

    Exec-Program-Wait = "/bin/sh /usr/local/etc/raddb/scripts/datacounter_auth.sh amir daily"

And this is clients.conf file:

client "mik" {
    ipaddr = 10.1.2.2
    proto = udp
    secret = 'admin123'
    require_message_authenticator = no
    nas_type = other
    ### login = !root ###
    ### password = someadminpass ###
    limit {
        max_connections = 16
        lifetime = 0
        idle_timeout = 30
    }
}

iphone – Does iOS hide your Wifi SSID information from your apps?

I recently asked a very similar question for Android, where it is a serious concern that any app can record what Wifi SSID you’ve connected to.

To quote:

This means that even if you are on a VPN, even if you turn off wifi
scanning, even if you turn off location services and take out your sim
card, even if you stop broadcasting your router’s wifi SSID, your apps
will be able to know what wifi SSID you are currently on.

This means that an attacker (read: the surveillance capitalism 🙂 ),
can figure out if/when I am home, and which other devices that
are/were online have used the same SSID. E.g. all my family’s
(mandatory) banking apps will know where my family members congregate,
and could change my insurance score, or other “insert dystopian
scenario here”.

Considering what I described, I don’t think there is any wiggle room
for you to ever hide your real location from a bad (state, corp,
hacker) actor. Am I wrong? Can I hide my SSID from the apps that are
on my phone?

Is this also how iOS works? I’m aware apple knows what color underewear all of your family members are wearing, and that it is selling (yes, sells less data than others but still also sells data) or otherwise using conclusions from analyzing that data and then sending/selling, to other services and/or third parties. But, does it technically allow apps to build this kind of connected device (e.g. SSID) history?

Also, (since I’m less familiar with iOS) is there a feature where your iPhone constantly scans all devices around you (wifi and bluetooth) to improve location or other features? And if so, do specific device names (e.g. bluetooth devices you’ve never connected to but are always around you) ever end up being visible to your apps? (and how to prevent that)

wi fi – How to hide your SSID from apps / keep your Android apps from finding your Wifi SSID?

As far as I know, all android apps are able to scan nearby / available Wifi networks. They can either get a list of nearby SSIDs, or at least they can get the SSID of the Wifi you are currently on. Correct? I remember the “get wifi scan results” unrevokable permission from some time ago (stoppable only if you were rooted and had xposed framework) (Also, exhibit B: Google, SkyHook, and Apple SSID databases).

This means that even if you are on a VPN, even if you turn off wifi scanning, even if you turn off location services and take out your sim card, even if you stop broadcasting your router’s wifi SSID, your apps will be able to know what wifi SSID you are currently on.

This means that an attacker (read: the surveillance capitalism 🙂 ), can figure out if/when I am home, and which other devices that are/were online have used the same SSID. E.g. all my family’s (mandatory) banking apps will know where my family members congregate, and could change my insurance score, or other “insert dystopian scenario here”.

Considering what I described, I don’t think there is any wiggle room for you to ever hide your real location from a bad (state, corp, hacker) actor. Am I wrong? Can I hide my SSID from the apps that are on my phone?

I can’t believe there aren’t any hits on this subject on the internet.

(PS: obviously, the point of the question is not whether or not I am paranoid, the question is whether this is technically solvable)

20.04 – Installed Ubuntu 20.01 on Lenovo Ideapad 130S-11IGM with 2GB RAM, no wifi and no additional drivers found

I was recently given a Lenovo Ideapad 130S-11IGM, and it has 2GB RAM. After some research I learned that Ubuntu 20.04 requires at least 4GB, although so far it seems to be working smoothly on my 2GB. However, I need to connect to wifi, and it says no additional drives available. How can I remedy that?
Is this issue perhaps due to a lack of space, or something else?

wi fi – Switch from Wifi to mobile data while roaming

We use international SIM cards in our our standard Android phones (SAMSUNG XCover4s). When they opperate in a weak Wifi environment, we would like them to switch to the mobile data connection (even though its on roaming), so my question is:

Is there a way to activate the “Switch to mobile data” option in the “intellegent Wifi” option of Android (10), when the device is roaming?

We have full access to the devices. Current Android Version.

Thanks for any help/hint.

Unfortunately I only have the screenshot in German:

iphone – Does recipient of WiFi call to toll free number know where you are calling from?

I have a US telephone number for my iPhone. Currently I’m traveling outside the US and need to call a US toll-free 888 number. When I call it using WiFi calling, I get a recording saying I cannot call that number. But I can call other 800 numbers. Can the owner of the 888 number tell that I am outside the US even though I’m using a US number over wifi?

wifi – 5th Gen Airport Extreme Randomly drops connection – but only on some devices

Here’s the situation: I am using a brand new MacBook Pro, and thus far all seems well.

I have a 5th Gen Airport Extreme that has worked well for nearly a decade. (I hadn’t realized it was so long, but there you are).

So lately what’s been happening is my wife’s devices seem to randomly lose connections. She has to have our internet connection function, so clearly this is a REAL problem. She is using a ThinkPad / Windows machine and connecting to a work VPN.

The other device she has is a late model iPad mini, which recently lost a zoom meeting.

I have had no problems with the Internet but she seems to run into a problem about once a month, where she gets randomly kicked off the network and it takes a minute for everything to find it again.
Anyhow, I had a few ideas as to what is wrong, but I need some help even figuring out how to diagnose this. Our ISP is Spectrum, and they said all is well with the modem (an Arris DG167OA I think, that is directly connected to the Airport Extreme)

My ideas:

  1. Distance. The problem is just that she is in the kitchen about 20 feet from the router, through a couple of walls. The thing is, I have worked out there too (on the terrace) and never had a problem yet.

  2. Some weird compatibility issue since the problems seem to come up most often with the Windows machine and recently I was able to get her on the Internet using a local hotspot from my phone (which was set to Wifi)

  3. Something I haven’t thought of, related to the age of the router.

What I have done: firmware is version 7.8.1, and I am not getting the “update” notice.
Haven’t tried hard reset yet, since we need Internet to work (so I likely need to do it at night or something)

I have an airport express I bought also some years ago (it was originally hooked up to the stereo to play music) and maybe that could help extend the network if that’s the problem, but do let me know.
Any ideas welcome . Thanks!

Also: if anyone has suggestions for an Apple Router to buy please tell me; the only ones I saw were $500 and that seems crazy compared to what I spent years back. I need a solution that “just works” — I am not interested in playing Tech Support Guy as I have a job too, you know?
