    When will there be a fix for this problem?
    Solution 1 doesn't work all the time. And solution 4 has other problems in my network. And solution 3 isn't where I bought my Firewalla for.
    And solution 2 I have a very expensive home network (unifi) what I use for dhcp.

    Please come with a solution so Firewalla works normal with android 14.

    Unfortunately, this is not something firewalla can fix. It is how the Android operating system deals with ARP spoofing. 

    If you own one of the Purple/Gold units, it is best to run them in router/bridge mode, these modes doesn't rely on the arp spoofing trick to grab traffic, and likely much more stable.

    This is also happening with a Motorola phone. Neither option 1 nor 4 works on my Red. I just get a no Internet message. Any other tricks?

    We believe the issue is related to the android operating system and arp spoofing. If none of the work around in solution 1 work for you, you should use the DHCP mode on the RED.

    If you have purple or gold, the best is still router (or bridge mode), these do not rely on tricks like ARP spoofing

    I just want to add for the purpose of google search, that the Samsung OneUI 6.0 update caused similar behavior with my S23 Ultra.

    Followed these steps to get a stable connection again.

    S23 ultra, S22 Plus and S21 are all doing this as well for me. I am using Firewalla Blue Plus at 2 different locations and now in the process of switching to Golds. Wasn't exactly what I wanted to do, but I am going to stick with it.

    Also just to add, non of the steps above worked for me other than router mode.
    I've also found my devices were negatively affected only if they were on a wifi6 connection.

    @wh39, likely newer Android (14?) overall does not like arp spoofing used in simple mode. 

    As of your case, if wifi 6 connection, it can be issue with your router; did you change nay router recently?

    I've unplugged my Blue+ and it will remain unplugged until this issue is resolved.  I'm not going to ask every guest and family member to change their Android phone to meet my network requirements.  I'm not going to turn off monitoring Android devices.  The vast majority of traffic I blocked came from Android phones.  And I'm not going to use DHCP mode with issues like "Our recommendation is to disable monitoring on the satellite mesh devices in the Firewalla app."  What's the point of having Firewalla if it can't monitor the satellites?

    @scott, the issue is not firewalla, but how Android 14 is working. Have you tried to use DHCP mode?

    I did read the info above!  I understand this is an Android issue.  No, I did not try DHCP mode.  As I said originally, I'm not going to use DHCP mode with issues like (from your website) "Our recommendation is to disable monitoring on the satellite mesh devices in the Firewalla app."  What's the point of having Firewalla if it can't monitor the satellites?

    Mesh AP units most of the time DO NOT send/receive traffic;

    Scott, just to try to be clear, that comment from Firewalla about satellite mesh devices only applies if you are using a product like a Linksys Velop router with wirelessly connected additional access points.  Only those extra access points would need DHCP disabled since the main router node manages the satellite nodes.  

    I would love to convert my 3-year old Red to DHCP (or upgrade to a Blue+!) but it's just not reliable - about every 4-6 months it just decides to quit working and I have to completely reload a fresh copy of the OS on the microSD card and re-import all the rules from the previous configuration.

    I am equally frustrated with the situation but generally love the Firewalla product and recommend it especially to non-techie friends who want to have control of their network.

    Hi,

    I just updated my Samsung S22 to the latest OS update and started running into this problem.

    Pls find a "real" solution to this or my firewalla's usefulness will go down a lot and I may have to quit using firewalla. Do note I have had firewalla for a few years and have loved it. But not having the ability for android phones to connect properly to my network is not feasible.

    But would have to disagree with comment that it is not firewalla's problem.  It is, if I turn off firewalla I can connect to wifi.  Firewalla needs to find a solution that is compatible with this android change. Android and IPhone are the most popular devices in the world so things need to work with them.  If not you just won't be relevant.
