Why does wlan1 not get a static IP?

Why does wlan1 not get a static IP?

I have a Raspberry Pi with two USB wlan adapters. wlan0 is configured with DHCP and wlan1 is configured with a static IP address and hostapd (access point) is running on this interface. The adapter supports master mode. But wlan1 never gets it’s IP address after boot and the network does not work properly. Any clues to why?

What can I do with two static IPs?

ISP modem -> unmanaged ethernet switch -> two Fortinets (one using DHCP, other using static IP address) The owners have a second static IP address that is not being used for anything. They would like to be able to access their camera’s DVR through the internet and possibly use a separate router for only employees.

How is DHCP used in multiple static IPs networking?

One is running off of DHCP that provides internet to a POS system and the other is using a static IP address that allows public internet access to the customers of the cafe. ISP modem -> unmanaged ethernet switch -> two Fortinets (one using DHCP, other using static IP address)

Why are my devices not picking up static IPs?

The strange thing is that when one would be picked up from the ISPs end, the other static IP address would not be picked up, and as a result whatever device was connected to that static IP address wouldn’t work. I’m not a network expert, so this is very confusing for me.

When is eth0 IP address is lost and not renewed?

I use eth0 interface on RPI 3B+ with DHCP and when cable is disconnected then IP address is lost and when cable is reconnected then IP is usually not renewed. I tried to set static address in /etc/dhcpd.conf but the issue is similar (+ debug option).

Do you need static IP for Ethernet port?

The ethernet port is connected to a DMX interface box. In this case, a static IP is not needed for the ethernet port since I am only transmitting data to the DMX interface box. However, I still cannot load webpages or run the apt-get upgrade commands. The process seems to be held up on connecting to a server.

When to use DHCP for eth0 and wlan0?

Feb 23 09:33:01 pren7 systemd [1]: dhcpcd.service: Unit entered failed state. Feb 23 09:33:01 pren7 systemd [1]: dhcpcd.service: Failed with result ‘exit-code’. So can’t I use DHCP for wlan0 when I configure eth0 using a static IP? Is there a workaround?

Why is my wlan0 unable to bring up?

However, when I checked using command ip addr state of wlan0 was down. Then I stopped networkmanager and switched back to the network scripts of Arch. My eth0 needs static IP which is correctly configured in /etc/rc.conf and it does work.

How to bring up wlan0 using iproute2?

After setting everything up, I tried to bring up wlan0 using iproute2: However, when I checked using command ip addr state of wlan0 was down. Then I stopped networkmanager and switched back to the network scripts of Arch. My eth0 needs static IP which is correctly configured in /etc/rc.conf and it does work.

Why is my wlan0 not getting an IP?

So wlan0 is connecting fine to my router, but I’m not getting an IP. Changing manual to dhcp doesn’t seem to help, I get lots of messages of the form: And eventually it fails. Perhaps it’s looking in the wrong place? I’m fine to either configure a static IP or get DHCP working.

Why is my Raspberry Pi static IP not working?

Disable ifplugd, then static IP address should work. I suspect that hostapd reinitialises the interface which is what causes this to fail. You can manually add the ifconfig command to the /etc/rc.local file which will auto-execute it on boot.

How to start wlan0 on a Raspberry Pi?

I would be trying to add the following lines just above your current wirless interface config: This tells your interface config to start the wlan0 interface automatically, and that it may be inserted later (hotplug). You may also need to add a gateway line as well to get routing working.

Can a Raspberry Pi access a wlan0 IP address?

The ip address configured for wlan0 should now appear if ifconfig is issued. If this is the case you should be able to access the Rasperry Pi using ssh with the IP address configured for wlan0. I hope you are happy and everything works fine for you so far.

Is there an IPv4 address for wlan0?

At this point even no IPv4 address will be shown for wlan0 if ifconfig is issued In case it fails and you didn’t do anything wrong so far (carefully check for typos), then you have another issue that must get fixed first; in this case this solution is probably not for you.
