Netgear firmware update issues

Netgear firmware update issues DEFAULT

It’s extremely annoying when your ISP (Internet Service Provider) promises you a good modem router combination, and then issues start occurring. That’s the deal with Netgear firmware updates getting stuck.

This is supposed to be an otherwise automatic upgrade/update system, and it should happen without you, the user, noticing that it ever happened. So, the user experience should be flawless and there should be no interruptions in your hardware’s functioning.

What Is Firmware?

Firmware is an operating system of any device that has greater technological functions. This means that current washing machines, refrigerators, routers, modems, etc. all have operating systems.

When you think of a laptop, the main operating systems we come across are Windows, Linux, and Mac OS. However, the fundamental operating system of any computer or laptop is BIOS (Basic Input/Output System).

BIOS is the firmware, and it’s just basic code, data, and memory that works to boot our computers and laptops. You can also find firmware in traffic lights, cameras, watches, even our blenders. It’s a necessary part of any hardware that makes our lives easier.

Why Firmware Updates Get Stuck?

When a firmware update gets stuck, it can be something as simple as a glitch in the system, or it can be something much worse. Sometimes, we might need to buy a new piece of hardware to solve the problem. Let’s see the reasons firmware updates get stuck:

  • Power outage: If there’s a power outage at the ISPs headquarters, or there’s a power outage on the server that’s supplying your internet connection, it interrupts your automatic update.

It can also be the node that’s closest to your home. Here, there’s not much more we can do. We need to do a reboot for the router. That’s the only thing that can help.

  • Firmware issue: There might be an issue with the firmware itself, and this means that you should get a replacement or a refund. You can’t do a lot if the firmware has an error in its code.
  • Hardware damage: Physical damage to the cables or the hardware itself might lead to an interruption in the power supply, and this might keep the update stuck. If you notice any physical damage, check if it voids the warranty.
  • ISP issues: When the hardware manufacturing company issues an update for the firmware, they provide this firmware to the ISP. From that point on, the ISP distributes the update to their subscribers.

If there’s been a breach of contract between the ISP and the manufacturer, some problems might occur. However, it’s best to contact the ISP to figure out what’s happening.

Netgear Firmware Update Fixes

Knowing why firmware updates usually get stuck, we need to understand that there are a few things we can do to resolve the situation with the Netgear firmware update that’s stuck. Let’s go over these in more detail.

Factory reset

As always, a factory reset should solve any glitches or bugs with the firmware or functionality of any hardware. To do a factory reset on any piece of Netgear hardware like a router, extender, etc., just find a button that says Reset.

By pressing and holding the button for over 30 seconds, you revert your Netgear router or modem to its factory settings. This should definitely resolve the Netgear firmware update being stuck.

Manual update

If the power supply gets interrupted at any moment, you can always try to update the firmware on your Netgear hardware manually. The thing you need to do is go to Netgear’s support page, and you need to find your router’s model.

Once you find the model, you can click on Downloads, and you can select the firmware version you need. Download it, and log into your router’s web page. You can use the www.routerlogin.net address to log in, or you can follow different Netgear login directions.

Either way, once you get to the web page, go under the Advanced tab, find the Administration section, click on Firmware Update, and upload the file from your computer. The router needs to finish restarting after that, don’t disrupt the restart, and everything will work properly.

Netgear Firmware Update Stuck

Firmware downgrade

Sometimes, our hardware works better with the previous version of the operating system. You can downgrade to the previous version and you might not need to update it at all. The steps are the same as with the manual update.

Check the internet connection

The reason your Netgear firmware update is stuck might be the internet connection itself. If you’re working with Netgear’s router connected to a different modem, check out the connection to the modem.

Look for damages on the Ethernet cable. If there are none, try to test it on two different devices to see if it works as a connection between them. Also, there might be an issue with the modem’s internet access point.

Check for damage on the coaxial cable to see if that’s the reason the firmware update got stuck. Interruptions in the connection to the internet access point can cause many glitches, even in the firmware update process.

Why Should You Contact Your ISP?

The reason you should contact your ISP when a firmware update gets stuck is that they need to know in order to improve their service to you and other clients. The more people report the issue, the more pressure the ISP feels to test a new firmware update on the routers/modem they provide.

If the tests go well, they might distribute a new update that works properly. Also, if they can’t handle your situation, it might be time to look for another provider.

Conclusion

Firmware is a necessary component of every sophisticated piece of hardware we come across. It’s necessary to maintain it, and it’s very annoying when we try to update it, but it takes an eternity.

The Netgear firmware update gets stuck because of multiple reasons, but we can fix it by doing a factory reset, a manual update, a downgrade, or by establishing a proper internet connection. If all these fail, it’s best to contact customer support of your ISP or Netgear.

Firmware Update Causes More Problems than it Solves

You have the R?

What firmware are you currently on?

there has been issues with the firmware for the R but the vast majority of people don't have these issues. You see many posted on here but thats because the community forum is where people come with issues. 

 

If you are one of the unlucky ones that has a device with firmware issued, the version I'd recommend and that tends to be the most stable is

From what I've seen with the R, the best results have been to install over an ethernet connection, factory reset after the firmware change. Most can install from backup without issue but I tend to recommend a manual reinstall so an old setting doesn't cause issue. 

 

And this is the community forum. Its rare to find an actual employee of netgear on here. 

 

The other thing to keep in mind is that router was released in Its 7 years old. I'm fairly impressed that its still getting updates at all being that old. My tp-link from 2 years ago hasn't gotten a single update since release.

Netgear not working Modem/Router/Repeater firmware update with TFTP Client software
Back of a router with antennas up

It’s easy to overlook that routers get firmware updates. These updates are not brought to people’s attention, but are important and should be checked on periodically. Firmware updates can be done through Netgear’s Nighthawk app, but sometimes the router simply refuses to do it. What should you do in this instance?

If your Netgear router is connected to the Internet, but won’t update its firmware, factory reset the router and turn off auto-updates. In same cases, the auto-update feature is the culprit, and can soft-brick the router, causing it to not function as it should.

This is an odd issue, but one that some people encounter. There are several other issues related to a Netgear router not updated and this article will go over some troubleshooting tips.

Netgear Router Stopped Working After Firmware Update

Router on a wooden table

Sometimes a firmware update can “break” a router. The most common issue resulting from this is a WiFi signal failing to broadcast. Considering most folks rely on the Internet in their daily lives, this is a very serious problem.

The first thing to doing is to reset the router to its factory settings. Doing this is very simple. Here are the official Netgear router factory reset instructions:

  1. Verify that your router’s power light is on.
  2. On the back of your router, locate the Restore Factory Settings or Reset button.
  3. Use a paper clip or similar object to press and hold the Restore Factory Settings or Reset button for seven seconds.
  4. Release the Restore Factory Settings or Reset button.
  5. Your router resets.

From there, follow the setup process that you did when you first got the router.

After the router has been reset to factory default settings, follow the setup process you went through when you first got the device.

Why do a factory reset? New firmware can introduce changes that are not compatible with an old configuration. By doing a factory reset, you wipe out user-enabled settings that might be in conflict with the new firmware.

You can also power cycle the router by shutting off all devices connected to it. Unplug both the router (remove the backup battery if it has one) and modem. Then wait 2 minutes for all the power to discharge before plugging everything back in. Restart all your devices and wait for the modem to establish a connection to your ISP.

Netgear Router Won’t Update Firmware

A man plugging in an Ethernet cable into the back port of a router

Normally, you should be able to update your router’s firmware from either the Nighthawk app or a Web browser. However, some people experience an issue where their router fails to update its firmware during the process.

It’s entirely possible that Netgear released a bad firmware that some routers can’t get past. We’ve ventured through the official community forums, and this indeed does happen to some people.

But before jumping to conclusions and requesting a replacement, try to downgrade your router’s firmware. To do this:

  1. Visit the support page and navigate to the corresponding section that your router falls in.
  2. If you have a standard router, click on “WiFi Routers.”
  3. If it’s an Orbi mesh system, click “Orbi WiFi System“; if it’s a Nighthawk WiFi System, click “Nighthawk WiFi System.”

From there, navigate to your specific model and click on downloads. How do you find what your model is? Underneath or behind the router, you’ll find Model: model number. It’s on the same side where the default password is printed.

Click on DOWNLOADS, then Previous Versions, select an older firmware version and download. The install instructions will be in the release notes, which are different for each router model.

Netgear Router Firmware Upgrade No Internet Connection

If your router isn’t connecting to the Internet after a firmware upgrade, similar problems and solutions apply to an earlier section in this article.

You may need to factory reset the router if you aren’t getting a connection. The reason being that new firmware can clash with settings that the user used.

here are the official instructions to factory reset the router from Netgear themselves:

  1. Verify that your router’s Power light is on.
  2. On the back of your router, locate the Restore Factory Settings or Reset button.
  3. Use a paper clip or similar object to press and hold the Restore Factory Settings or Reset button for seven seconds.
  4. Release the Restore Factory Settings or Reset button.
  5. Your router resets.

How To Fix Corrupted Firmware on Netgear Router

If you have what is essentially a bricked router, don’t panic, this can be solved easily in most cases.

  1. Refer to above, where we discussed how to found your router’s firmware version. This time you’ll want to download the latest version.
  2. Next, download the TFTP client software. That’s the Windows link; here is the link for Mac. If you are reading this on your smartphone’s cell tower data, you will need to plug your computer into the router directly with a LAN cable.
  3. Assign a static IP of the router’s default range, which is either x or x.
  4. Ping your router’s IP.
  5. Run the tftp2.exe.
  6. In the server field, punch in the default IP of the router.
  7. Shut off the router for 10 seconds and turn it back on.
  8. While the router is booting, click Upgrade and allow the process to complete.
  9. The power light should be a steady green now; in that case, the fresh firmware is successfully installed!

How Do I Reinstall Firmware on My Netgear Router?

Man configuring a router using a smartphone app

Refer to the section where we instructed on how to download the correct firmware for your router. If you were already on the latest firmware but just need to reinstall it, you can do it via the browser, provided the router isn’t corrupted. From Netgear’s website:

  1. Unzip the downloaded file if needed.
  2. Enter routerlogin.net into a web browser.
  3. Enter the router admin username and password.
  4. The default user name is admin. The password is the one you specified the first time you logged in. The user name and password are case-sensitive.
  5. Select ADVANCED > Administration or Settings > Administration.
  6. Select Firmware Update or Router Update.

What if My Router Is Hard Bricked?

The back ports of a router

Hard bricking refers to a rendered completely useless device and cannot be restored via conventional methods. This may happen if there is a power outage while the router is updating its firmware, and this scenario can happen to almost any device where you would update the firmware, such as a smartphone or game console.

Your router comes with a one-year warranty that needs to be registered with 90 days of purchase, but unfortunately, a hard-bricked device due to a power outage or disconnection isn’t covered.

From the official warranty page:

“This warranty does not apply if the NETGEAR product fails due to damage from shipment, handling, storage, accident, abuse or misuse, or if it has been used or maintained in a manner not conforming to product manual instructions, has been modified in any way, or has had any serial number removed or defaced.”

There is hope, however. Some retail stores have a very pro-consumer refund policy, and you may be able to get a refund or replacement if you got your router there. Amazon is also quite forgiving most of the time.

If you had an old router and were considering upgrading anyway, you might be wondering what your best options are. It depends, but generally, you don’t need a crazy $+ model. We recommend looking for a model that supports WiFi 6 since more and more devices are beginning to utilize it, and it does make a big difference.

The Netgear 4-Steam strikes a good balance between performance and price and should be suitable for most homes. Alternatively, a mesh WiFi system such as the Netgear Nighthawk Mesh System might be better if your home is large. We’ve linked a video below for even more suggestions:

Final Thoughts

Having any problems with a router can be frustrating since it allows people to connect to the vast world of the internet. Many people don’t use ethernet, and thus it is quite a big deal when your router is rendered useless due to broken firmware. However, with some troubleshooting and fixing, you should be able to get it up and running again!

Thousands of Netgear routers can be hacked — here's what to do

Dang kids. Because of an optional parental-control feature that apparently wasn't so optional, nearly a dozen widely used Netgear home Wi-Fi router models have a serious security flaw and need to be patched.

The affected models are the Rv2, R, Rv3, R, RP, R, RP, R, R, R and RS, most of them in the "Nighthawk" line and physically nearly identical. Firmware updates are now available for all of them. 

The flaw can be exploited by a bad guy who gets access to your Wi-Fi network, which may not always be as hard to do as it seems, and then used to seize control of your home or small-office network and send you God-knows-where on the internet.

Because Netgear markets its home routers using somewhat misleading terminology — for example, the R is also labeled as the "Nighthawk AC Smart WiFi Dual Band Gigabit Router" — you might want to flip your router over and check the sticker on the bottom for the real model name.

How to update your Netgear router's firmware

To update your router's firmware, Netgear's security advisory recommends going to its support page at https://www.netgear.com/support/, then punching in your model's number. From there, you'll be taken to your model's support page. You can download a Zip file to your PC and unpack the file. 

Then use your favorite web browser to access your router's administrative interface (it's most likely at http://), click the Advanced tab, select Administration and click Router Update. You can upload the file to the router from there.

However, for most of these routers, it's going to be just as easy to download the firmware update directly to the router. Follow the web administrative-interface instructions in the paragraph above, and then click the check-for-update button instead of uploading a file from your PC or Mac.

Vulnerable Disney Circle software

The problem here stems from the Disney-designed Circle parental-control feature, which was rolled out to Netgear Nighthawk and Orbi mesh routers, some of them already in customers' homes, as an optional add-on feature in  

The Orbis and newer Wi-Fi 6 Nighthawks got parental-control software built in-house by Netgear earlier this year, while the Circle service was discontinued for older Nighthawk models in late

Here's the catch: If you have one of the affected routers, the vulnerable Circle software is on your device regardless of whether you ever ponied up the $ monthly charge for the Circle feature. 

"The Circle update daemon that contains the vulnerability is enabled to run by default, even if you haven't configured your router to use the parental control features," explained Adam Nichols of the D.C.-area security firm GRIMM in a blog post. (Bleeping Computer earlier reported this story.)

"While it doesn’t fix the underlying issue, simply disabling the vulnerable code when Circle is not in use would have prevented exploitation on most devices."

In other words, you've got a problem that came with software you probably didn't ask for and that may have been introduced to your device via a firmware update after you bought it. 

We've run a lot of Netgear router security alerts in the past few years, with at least twoin So we want to reiterate that Netgear's consistent policy of finding, patching and publicizing its security flaws is a Good Thing, despite the resulting negative headlines. 

The only reason you don't hear about many security flaws with some other major router makers is because they don't tell you about the flaws. At least we know when something goes wrong with Netgear routers and how to fix it.

The same principle goes for Windows PCs, Macs, iPhones and Android phones. All of those devices get regular security updates to fix flaws and are the better for it. You don't want a router that never receives firmware updates.

What's going on here?

This flaw, catalogued as CVE, was discovered by GRIMM researchers. They noticed that there was a Circle update daemon, or mini-program, called "circled" (presumably pronounced "circle-dee") on older Netgear Nighthawk routers.

After some probing, they found that the Circle update daemon ran as root, was enabled by default and could still be exploited even if it was disabled.

"The update process of the Circle Parental Control Service on various Netgear routers allows remote attackers with network access to gain RCE [remote code execution] as root via a Man-in-the-Middle (MitM) attack," Nichols wrote on the GRIMM blog. 

Because Netgear's firmware updates are downloaded over plain old HTTP and are not encrypted, Nichols explained, they could in theory be intercepted, altered, and then passed along in poisoned form to the routers — a classic man-in-the-middle attack.

Netgear protects against this by encrypting its firmware update files and digitally signing them, making it pretty difficult for an attacker to read, alter or install altered firmware.

Not so Circle. Its update file is just a compressed database without any kind of internal protections. 

GRIMM showed that it wasn't hard to sneak malicious code into a Circle update and from there completely seize control of a router, which in turn would grant the attacker complete control of your home (or small office) internet traffic. 

This may not entirely be Circle's fault. It could be that the firmware-update connections on its since-discontinued Circle with Disney hardware devices were encrypted, removing the necessity of encrypting the update files as well. 

If so, then this new flaw may be the result of something falling between the cracks in the differing update models when the Circle software was ported to Netgear devices.
