I have set my Raspberry Pi 3 as a wireless router per instructions here, so that now it has the following contents in /etc/hostapd/hostapd.conf.
interface=wlan0
bridge=br0
ssid=rspi
hw_mode=g
channel=7
wmm_enabled=0
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=12341234
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
It now broadcasts the expected SSID ("rspi"), but none of my wireless devices can connect to it because of wrong password, even though I check closely that the password I type to connect is 12341234.
I tried in vain to change the channel number to 1, 6, and 8.
Any idea on how to resolve this?
Incorrect password can often mean that something else is wrong. I know when my raspberry pi says the password is wrong, and I know it's right, it's either still booting or it's failing to authenticate. Don't know how to fix it besides rebooting/ reimagining it to start the setup from scratch.

I am attempting to connect MATLAB with a Raspberry Pi 3+. Using the application installer in MATLAB, I downloaded and installed the necessary support hardware (https://www.mathworks.com/hardware-support/raspberry-pi-matlab.html) and then used the configuration dialog in those apps to flash a microSD card. Booting the Pi with that card, I set up passwordless sudo and enabled SSH. Using an ethernet cable to connect my laptop with the Pi, I can ping the Pi from MATLAB, and I can SSH in using PuTTy. However, when I try to connect in MATLAB (having opened MATLAB in admin mode), I get the following error:
I'm not sure where to go from here -- this error isn't listed on MATLAB's help page, and I cannot find anything online. Any help is appreciated.
Answer is straightfoward: problem found between user and keyboard. The device address should ONLY be the IP address of the Pi.
I have one device that is bluetooth PAN capable and had success with a different raspberry pi. I think I messed up the configuration files on this new one but didn't change them before I enabled some process that I beleive created the pan0 network interface (seen in ifconfig). This is the guide I used "prog.world/raspberry-pi-pan" and I think I put in the wrong Address in /etc/systemd/network/pan0.network. I later tried to alter that interface with "ifconfig pan0 <actual IP 192.168 address that I assume is correct>. I tried to connect again and still am not recieving any info but I get confirmation that the connection is up and running on both sides. Could there be a way to restart or edit something to fix this? Look at the guide I mentioned above. Not sure how this all works after I make the config network files but it might have happened when I did the "sudo systemctl enable" command for systemd-networkd, bt-agent, and bt-network. Maybe there is another file I need to change the IP on?
I've an issue connecting with my raspberry from a specific computer on home network.
Raspberry is connected on WiFi and my computer is connected on LAN.
The issue occurs only on the actual raspberry IP that is a static IP (192.168.1.3. This is correctly reached from every other device in the home network.
If I change the IP assigned to raspi it becomes reachable from my computer but I don't know why.
I've tried deleting DNS cache from the computer and checking Firewall rules but nothing found. I've also checked raspi to see if there are rules blocking the connection but nothing found here too.
Could you please help me understanding why this is happening? I would like to keep the actual IP assigned to the raspi.
Thank you
I have a nodejs server in my raspberry and I want people to be able to connecto to it just connecting to the raspi.
The ideal scenario is where in my phone I see the raspi SSID, I connect to it. Then I open chrome enter the ip:port of the raspi itself and it works. Nothing fancier.
What I don't know how to search for in the internet is how to set my pi in a way that it opens itself to the world and appears in the SSID list in my phone. I don't need internet sharing nor anything. Just accessing the nodejs server in the pi.
This can be easily achieved depending on the OS you are using in your pi. Use basically need to use hostapd and a DHCP Server.
You can use a script like create_ap.
I want to install MATLAB and Simulink support package for Raspberry Pi. I follow this link to do . I directly connect my laptop with Raspberry Pi using Ethernat cable.
But i didn't get output.
while installing i got error - "Could not detect a Raspberry Pi board on "Local Area Connection". Check your Ethernet connection to Raspberry Pi.
The FDX/LNK/100 LEDs on the Raspberry Pi board should be illuminated.
For network trouble-shooting instructions see http://www.mathworks.com">The MathWorks Web Site"
Can anyone help to solve this problem?
I have also experienced your same issue but after proceeding in this way I solved it.
Before you put the SD card on the Raspberry Pi you need:
power off the Pi
connect the Ethernet cable to the host computer
finally power on the Pi
In addition you may take a look at this troubleshooting guide.
Try the following steps.
1. Open cmd and execute 'ipconfig'
check for a network interface with '169.x.x.x' ip address
If there is one, you could access your Pi via IP 169.254.0.2
If there is none, check if your Ethernet port is enabled and no static IP is configured.
The above steps make sure that your Ethernet port is in proper state.
Repeat the hardware setup with direct connection in the network settings.
