MI424WR Rev. I Firmware Upgrades

Actiontec made this model device for several different Internet Service Providers (ISPs) and we never made a Non-Customer Specific (NCS)/retail version. So at the request of those ISPs, they have asked us not to post any firmware upgrades on our support site. So you will need to contact the ISP that your model came from based off the logo on your device. Also, if you purchased this device from another location other than your current ISP please refer to ISP whose logo is on the device for help finding the most current firmware. If you are still having issues please let us know below in the comments section.

  • It isn't Verizon -- it is Frontier. I am only asking about the F/W version 52.0.7 on a Frontier-supplied device because of your reply to an earlier post:

    ( November 2, 2017 -- "He was only asking if he could upgrade to the 52.0.7
    firmware. Which he cannot. ... MI424WR Rev I... was made for Frontier ".

    This would make it appear I shouldn't have been upgraded to this F/W version unless something has changed in the last couple of months (since 2 Nov 2017).

    Frontier indicated, in a call to their support line, that this was up-to-date/current but I am not particularly confident in the response they gave. I am not sure they had a configuration management table they looked at for this.

  • Dear Jadrian and Actiontec Support,

    Thank you for providing this support page. You are the Alex Tribec to all the fake Sean Connerys with old frontier routers in this world.

    One day I will stumble upon this thread again and be just as entertained. Thank you

  • Unforantly the contract that we have with Verizon does not allow us to post any firmware for the devices that we have manufactured for them. They do this so that they know every device on their network has the correct firmware. So we would have to direct you back to Verizon to obtain the firmware upgrade.

    Is there a reason you are looking to download that particular firmware?

  • Hi
    I have an Actiontec MI424WR Rev. I router with firmware 40.20.4.2. When I try to upgrade to 52.0.7, a notification appears "Bad upgrade file signatures.". How to upgrade it? I live in Russia and it does not work with my provider.

  • Now that there is the KRACK vulnerability, does anyone know if Verizon/Frontier have released a patched firmware? I am a customer of neither, but I do operate two MI424WR-Rev-I routers as MoCA bridges in my home networking setup and would like to upgrade firmware if possible. Mine are both currently Verizon branded.

  • I have a MI424wr Rev I router provided by Frontier. I tried to connect a wifi extender to the router and the WPS button doesn't seem to do anything. The extender failed to connect. After a long chat discussion with Frontier I am being told that the WPS button is non functional with the current firmware on my device. The WPS button was included on the router, but was to be enabled with a future firmware update. What I'm being told by Frontier is that there is no firmware update available for this router. My question is this, is there a firmware update that enables the WPS button on this router? I have read all of your comments about contracts with ISPs and not being able to release update except via the ISPs. I just want to know if there was an update that enabled the button.

  • That is disappointing to hear. Is there any alternative to the GUI for configuring the new router? I find the entry of MAC addresses into the DHCP static assignments particularly problematic, as even though I have them in a spreadsheet I cannot copy/paste them into the GUI.

  • Mike,

    What firmware do you currently have on your MI424WWR?

  • Subsequent to my comment above, I discovered a simpler solution on dslreports.com and it is:

    Disable DHCP : Go to Advanced - IP Address Distribution - Change to Disabled.

    Assign Static IP : My Network - Network Connections - Advanced - Network/Home Office - Settings - change the Internet Protocol setting to 'Use the following IP address' (192.168.1.2 / 255.255.255.0 works).

    Same SSID / Passphrase : Wireless Settings - Basic Security to change the SSID, Advanced Security to set the passphrase - I would also suggest using a different wireless channel than your primary router (like 1 on primary, 11 on secondary - set to maintain through a power cycle on both).

    No need to reserve the address on your primary router, just adjust the DHCP pool on the primary to begin with 192.168.1.3 (if you used 192.168.1.2 as the IP for the secondary).

  • Can anyone confirm that the MI424WR is not vulnerable to the Cable Haunt exploit? (https://www.zdnet.com/article/hundreds-of-millions-of-cable-modems-are-vulnerable-to-new-cable-haunt-vulnerability/)

    I know it's not on the published list...but not 100% sure it's an inclusive list.
    I'm using the MI424WR-GEN3I with firmware version 40.22.3.3 with Frontier (modem itself has Verizon branding emblazoned on it.)

  • Mo,

    What we meant to say is we cannot say if this device will work with your ISP or not. It was only designed to work on the Verizon network. It can be used just as a router but we do not recommend you using it as the main router for an ISP other than Verizon.

    Also, it has been discontinued so there will be no new firmware releases coming out for this device either.

  • Randy Gritton -- I suggest you first check: advanced> system settings > Configure number of concurrent users that can be logged into the router. It has been my experience that attempting to obtain firmware downloads from Actiontec for a proprietary device is too painful and will ultimately be unsuccessful. That leaves ISP support, which is also painful and time consuming. I am interested in how you solve the problem.

  • Morace,
    All support on those discontinued units is provided by Verizon.
    They may or may not have some of the features enabled/disabled but they would know which ones. Since these are built for the Verizon service they will automatically configure to their settings. The DNS name and IP should be configurable. You may have some sort of javascript security program or setting preventing changes.

  • Michael,

    40.21.24 is the most recent firmware for the Verizon MI424WR Rev. I. The site that you are referring to is a Verizon controlled site we here at Actiontec have no control over what firmware they put up there or why so, we cannot tell you why they posted an older version there. It is also Are understanding that the MI424WR Rev I has been discontinued by Verizon so no further firmware upgrades will be made available for your device.

    I have a Frontier aka Verizon running on MI424WR-GEN3I firmware 40.22.3.3, in the logs it says it failed to update to the latest so when i check frontiers' website. they show my model linking to https://frontier.com/helpcenter/categories/internet/other-services/open-source-software-portal from there it links to http://opensource.actiontec.com/mi424wri.html where i see 52.0.7 is an option. How do i get this version on my device?

  • Robert,

    You have the most current version. The 52.0.7 does not apply to your device.

  • Hi, I have a verizon router MI424WR Rev I. I have tried to update the firmware, but it is telling me it is up to date as version 40.21.24, released Jun 24, 2016. Is this the most recent update and if not, how can I update it? When I query the link on the update page (https://upgrade.actiontec.com/MI424WR-GEN3I/MI424WR-GEN3I.rmt), it points me to version 40.21.10.3, which sounds older, although it has one more digit in the version number.

    What is the latest version firmware version. Why does the update link point me to older firmware? Should I downgrade to 40.21.10.3?

    Thanks

  • Nick,

    The only way to obtain a firmware upgrade for the MI424WR Rev. I is from the ISP which you obtained it from. The http://opensource.actiontec.com/mi424wri.html website is only for people who know how to build their own firmware form the GPL source code. The 52.0.7 will not work on your unit. Your firmware 40.22.3.3 is the latest firmware for your unit and there is no upgrade for it.

  • I also have a Verizon MI424WR-GEN3I Hardware version I not 1. I wanted to change the DNS address on the router to use cloudflares new fast DNS service 1.1.1.1 1.0.0.1.
    Could you help me with the setup options. When I go in to DNS Server screen and atempt to edit the existing entries the only allows thing I am allowed to change is the host name.
