wireless networking – Outbound VPN is Blocked by a Physical Wall


Consider my typical home network, consisting of a cable ISP and retail LinkSys WiFi router.

My iPhone automatically joins the WiFi network when it’s in range. Installed on the iPhone is ProtonVPN, client software for a popular VPN provider.

The VPN client connects “on demand” and for the most part works flawlessly.


All connections over the VPN fail when the iPhone is used from a particular room in my home.

Using another VPN client (e.g. OpenVPN) or even a different VPN provider all together (e.g. BraveVPN) triggers the same problem.


The room in question has a concrete wall in the router-facing direction, so naturally one would assume that the WiFi signal is having trouble penetrating the wall, and perhaps I need a range extender of some sort.

Except that, while standing in the room in question…

  • The WiFi signal indicator shows full strength.
  • Manually disabling the VPN allows full connectivity to resume.
  • SpeedTest.net with VPN disabled shows 50ms latency, 80Mbps down, and
    10 Mbps up. The connection is totally solid from that room.

It’s only when the VPN is connected (any VPN, not just ProtonVPN) that connectivity is hindered, and only in that one room.

I’m familiar with the idea of a firewall blocking outbound VPN connections, but this case is unusual insofar as the connection seems to blocked by a physical wall.

Any idea what would cause an odd problem like this to manifest and how one would fix it?

wireless networking – Windows displays a globe icon and won’t automatically connect to WiFi

Sometimes when I resume my laptop from sleep or hibernate, Windows displays a globe icon in the system tray (instead of the WiFi strength icon) and doesn’t automatically connect back to my preferred WiFi network. I’m unable to access my home network or the internet in this state.

To resolve, I must click on the globe (which displays a list of WiFi networks), click on my chosen SSID (which already has “connect automatically” ticked) and then click on “Connect”.

How can I make it so that Windows always connects to my preferred WiFi network after it wakes up?

Is there a wireless modem with an ethernet jack?

I am in the market for a “mobile hotspot” but I have certain preferences that don’t seem main stream, and I’ve been having difficulty finding a hardware unit that meets any or all of these preferences.

What I want, ideally, is a 4G/5G modem that has an ethernet jack to connect my client machines to. Preferably, I DO NOT want wifi at all. I don’t need wifi to connect my client devices, and I view it as a security problem. The only wireless capability I want is to connect the modem to the 4G/5G network for internet, from there, I want a strictly wired connection.

Is there any device like this?

Thank you,

broadcom – How do I install wireless adapter for ubuntu 21.04 on Macbook pro 2019

I’m new to these forums and am a super noob to linux/ubuntu (I’m not sure how to do most things yet) and I’m having trouble finding help for this problem I’m having.

In the settings it’s showing “No Wireless adapter found”. I’m dual booting from my Macbook pro 2019 13.3 in with touch bar.

I’ve searched for previous solutions to this problem but none seem to work in my case. I ran sudo apt-get install --reinstall bcmwl-kernel-source and rebooted but it didn’t work. (I’m currently on ethernet direct connection but would like to move to wireless)

When running lspci -nn -d 14e4: I get:

01:00.0 Network controller (0280): Broadcom Inc. and subsidiaries BCM4377b Wireless Network Adapter (14e4:4488) (rev 04)

How exactly do I go about installing the proper drivers for my wireless network adapter?

I’d be happy to provide more information or run any commands if need be.

networking – How can I use a Linksys AC 1200 Wireless Adapter?

I tried following this guide, but when I ran sudo modprobe -v 8812au I received the error modprobe: FATAL: Module 8812au not found in directory /lib/modules/5.4.0-72-generic I also found this same guide in an answer to a question on how to get this to work.

I came across this thread where the OP was having the same issue, but it looks like he never received any replies. Does anyone have any ideas? I tried rebooting and doing everything again and the same thing happened. My other WiFi adapter that is actually meant for Linux and I believe uses Broadcom drivers works perfectly fine.

networking – Is it possible to have a wireless network and a wired network simultaneously, and to have different applications use one or the other?

Is it possible to have a wireless network and a wired network simultaneously, and to have different applications use one or the other?

For instance, to have Chrome use the wireless network, while everything else goes through the wired network?

I’m using Ubuntu 18.04 and Network Manager.


networking – Connecting Comcast modem, unmanaged switch, and wireless router correctly in small business

We recently purchased an Orbi Pro mesh router with satellites to extend the WiFi coverage in our small business. We have a cable modem (Comcast Business Gateway), an unmanaged switch (Netgear Gigabit), and the wireless router (Orbi Pro w/3 satellites).

If I connect the modem to the internet port of the router, and the switch to one of the ethernet ports on the router, then I have internet connectivity but can’t communicate with any of the devices on the switch:

Modem -> Router (Router Mode) -> Switch

Alternatively, if I connect the modem to the switch, then the switch to the internet port on the router, I am able to access some websites — but not all:

Modem -> Switch -> Router (Router Mode)

At first I thought this was a DNS issue, but I’m guessing it’s a routing issue, since there’s no router between the gateway and switch.

It seems the only configuration that lets me access all websites, and all of the devices connected to the switch, is to place another router between the modem and switch, then place the second router in bridge mode:

Modem -> Router #2 -> Switch -> Router (Access Point Mode)

I feel like I’m missing something here. Is there any way I can connect the modem, switch, and single router together so that I can access the internet and connect to all devices (both wired into the switch and wireless via the router)?

The only change to the modem configuration was to turn off WiFi. The only change to the Orbi Pro configuration was to switch between router/AP mode and enable WiFi. The switch is unmanaged.

Thank you!

ADB wireless :- problem with IP

I use adb wireless tcpip connection but every time I connect my device to my router it assigns a new IP address to my android device which requires me to plug my phone again and restart adb in tcpip with the IP address provided, I dont want this to happen every time, I just want to enter the same IP address and put adb connect <ipaddress>:<tcpip_port> and connect to my device.

i tried to use static IP for the network using the mobile but due to some reason this restricted me to use internet(it was connected to the modem but not able to use internet).

More info:

Android 10
redmi note 7s

i use scrcpy and have created a bat file(.cmd file) which when clicked runs a series of commands to connect to my phone wirelessly using adb and mirror the screen and control it remotely but because my router assigns a different IP ever time i connect my phone i have to edit the bat file.

Even if I type the commands manually without connecting the device with USB cable (adb connect <ipaddress>:<tcpip_port>) it says: unable to connect to <ip addr>:5555: cannot connect to <ip addr>:5555: No connection could be made because the target machine actively refused it. (10061) , then i have to connect it with USB cable and again start the adb in tcpip.

What is the use of adb wireless connection if I have to connect it to pc by USB every time (at the beggining) to make it wireless for that specific time.

Outdated: Lenovo default driver for Realtek 8822CE Wireless LAN 802.11ac PCI-E NIC

I found a driver that works at https://www.drvhub.net/devices/network/realtek/8822ce-wireless-lan-802-11ac-pci-e-nic (2024.0.10.129)

The problem was that no networks were detected.
