Did you make the wpa_supplicant file on Windows? Because, from the error messages, it looks as if it was it was saved as "rtf" and not as plain text. And if that's what happened, the pi will barf on it. Rtf files have lots of formatting information embedded in them which is no use at all for linux configuration. Try writing the file on your windows machine ...

The raspberry Pi showed a connection for longer than it was connected. When I tried again, it was no longer connected and could no longer connect to the router. The connection between the Pi and the router was across a courtyard and possibly heavy rainfall had disturbed the 5G connection, as this site mentions: The weather condition that has the greatest ...

I don't know how to show a hidden WLAN network with the WiFi Icon. I think it's by definition not to show it. But another main problem seems to be that wpa_supplicant modifies its configuration in /etc/wpa_supplicant/wpa_supplicant.conf. By default it has an option update_config=1 set that exactly allows modification and to disable a network section with ...

If you use wpa_cli you can use for example this script for a more 'user friendly' way ? #!/bin/bash # switchnetwork.sh LOCALNET=0 EXTERNALNET=1 function switch_to_local_net(){ echo "SWITCHING TO NETWORK ID $LOCALNET" wpa_cli enable $LOCALNET && wpa_cli reconnect $LOCALNET } function switch_to_external_net(){ echo "SWITCHING ...

OpenWrt is the best choice for you. It makes Raspberry Pi to a wireless router device and you don't need to run a lot of commands. Easy to use with an interactive web user interface named LuCi like picture below: I believe it going to help you better than in other ways. The thing you should concern is that you should don't attend this page. As this ...

It's weird. Sounds like HDMI signals conflicting with Wifi signals, however, change the cable to another one (better, if it has a shield it'd be better.) and add an external wifi dongle. If you change the cable, maybe you would realize that it's ok with "1920 x 1080" and it's not with "1280 x 720". The list below can help you. 1920x1080 working ...

Just download and install a Raspbian Buster image as described at Installing operating system images. Don't use NOOBS, instead flash a Rasbian image. Then enable WiFi as described at Setting up a Raspberry Pi headless and all is done. Connect and reconnect to an access point is doing out of the box on a default Raspbian installation. On my RasPi I see this ...

Every device that conform to IEEE 802.11 must support a wireless ad hoc network. In the specification it is called independent basic service set (IBSS). The supported interface modes of your WiFi USB dongle show that it also supports it of course. So IBSS is the keyword you have to look for your ad hoc network. You are using old style deprecated Debian ...

It is possible to forward traffic from the wired interface (eth0?) to the usb0 interface. Because you do not have provided any details about your network configuration I can only guess. You have to enable ip forwarding. There are several ways to do it: within /etc/sysctl.conf or by systemd-networkd or with /proc/sys/net/ipv4/ip_forward. Because you have ...

See How to set up networking/WiFi Most of us don't use NOOBS so its operation is a mystery. It is a violation of the licence conditions to activate a 5GHz network without setting country code, which is why it is disabled by default. Raspbian (at least a normal installation) prompts you on initial boot to set required parameters. NOOBS probably attempts to ...

Try swapping the two Raspberries around: I would expect that the one you connect via the Ethernet will still be the one that cannot be pinged. The problem then lies in the router (or whatever device you have which provides the Internet access to the rest of your network). ping sends data via Internet Control Message Protocol (ICMP), so that's what you ...

As far as I understand you want to have an access point that is connected with a WiFi client connection as uplink to your internet. All tutorials and automated scripts I know that work with the RasPi are made to use a wired uplink to the internet router router but not a wireless one. This is because it isn't an easy task to have a wireless access point and a ...

Your wpa_supplicant file should be something like : ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 country=FR network={ ssid="wifi name" psk="password" key_mgmt=WPA-PSK } key_mgmt is the type of security your wifi is using

I have a 2012 Samsung smart TV which has a dlna client. Like you, I cannot link my TV directly to the router using Ethernet cable. My Raspberry Pi 4 replaces (and works better than) a 2012 Seagate Goflex NAS (it died) which also had minidlna running. To connect the TV to the router I used what are called powerline adapters. They plug into AC outlets and use ...

SOLVED! First, I answered the bold question in part 1: "Where can I look to find more information about what exactly is happening during this failure?" The answer was in: pi@raspberrypi:~ $ sudo systemctl status wpa_supplicant.service ● wpa_supplicant.service - WPA supplicant Loaded: loaded (/lib/systemd/system/wpa_supplicant.service; enabled; vendor ...

You could also try this tutorial: Start with a clean install of the latest release of Raspbian (currently Buster). Raspbian Buster Lite is recommended. Update Raspbian, including the kernel and firmware, followed by a reboot: sudo apt-get update sudo apt-get dist-upgrade sudo reboot Set the WiFi country in raspi-config’s Localisation Options: sudo raspi-...
