Some Magic Jack users are seeing the 3002 Error code when attempting to plug in the device into a modem in order to use VoIP calling on a Windows computer. This problem occurs on every recent Windows version including Windows 10.
As it turns out, there are several different potential culprits that might contribute to the apparition of the 3002 Error code:
- Common TCP / IP Inconsistency – As it turns out, one of the most common causes that might cause this problem is an IP or TCP inconsistency. To fix it, all you need to do is restart your router in order to force your router to recreate the connections (including the one involving the Magic Jack device).
- Firewall interference – If you’re using a 3rd party AV that includes a firewall function, chances are it ends up interfering with the functionality of your Magic Jack device. In this case, you should try to uninstall the 3rd party AV suite and see if this ends up fixing the problem.
- Magic Jack ports are being blocked – With certain routers, it’s possible that the ports used by the Magic Jack device for VoIP are being actively blocked. In this case, the most efficient solution of getting the problem resolved is to create a static IP and then use it as a DMZ in your router settings.
- MAC Filtering is enabled – If your router is configured to actively use MAC filtering, the Magic Jack device is an obvious target. In this case, you can either disable MAC FIltering altogether from your router settings or you can whitelist it from the list of blocked MAC addresses.
Method 1: Restarting your Router
Before you try any other fix, you should see if you’re actually dealing with a common IP/TCP inconsistency. This problem is commonly reported by Magic Jack users the very first time when they attempt to configure the device.
But according to their reports, the fix is as easy as forcing the router to restart and recreate the connections. If the 3002 Error code is indeed being caused by a common network inconsistency, this operation will flush the DNS, IP, and clear the temp data that might be responsible for causing the issue.
To perform this operation, look at the rear of your router for the power button. Once you see it, press it once to turn it Off, then wait for 30 seconds or more before powering it on again. While you wait, you can ensure that the power capacitors are completely drained by physically disconnecting the power cable from the power outlet.
After you do this, restart both your router and your computer and see if you’re still encountering the 3002 Error code when connecting a Magic jack device.
If the problem is still persisting, move down to the next potential fix below.
Method 2: Disabling or uninstalling the Firewall
If you’re using a problematic router/modem combo coupled with a 3rd party firewall, chances are you’re dealing with an overprotective suite that ends up interfering with the functionality of Magic Jack.
This problem is only reported to occur with non-native Firewall suites like Comodo, Mc Afee, and Avira. We didn’t manage to find any users’ reports claiming that this problem was caused by Windows Firewall.
Keep in mind that if you’re using an old fashioned firewall, the same security rules will remain in place even after you close/disable the real-time protection of the security app. Because of this, the only way to determining if your firewall is indeed causing the problem is to uninstall it all together before drawing a conclusion.
Here’s a quick guide on how to do this:
- Press Windows key + R to open up a Run dialog box. Next, type ‘appwiz.cpl’ inside the text box and press Enter to open up the Programs and Features menu.
- Inside the Programs and Features menu, scroll down through the list of installed applications and locate the security suite that you want to uninstall. Once you see it, right-click on it and choose Uninstall from the context menu.
- At the uninstallation screen, follow the on-screen instructions to complete the process, then restart your computer if you’re not prompted to do this automatically.
- At the next startup, see if the problem is fixed by connecting your Magic Jack device once again.
In case the same problem is still occurring, move down to the next potential fix below.
Method 3: Create Static IP and set it as DMZ
If none of the fixes above have worked for you, chances are you’re using a router that distrusts VoIP services like Magic Jack. Some users that encountered this problem on Q1000 models and similar have reported that they managed to fix the problem by setting a static IP on their computer and then establishing that static ip as DMZ inside their router settings.
A home DMZ (demilitarized zone) is a host on the internal network that has all UDP and TCP ports open and exposed – which is exactly what Magic Jack devices need to function properly.
If you want to give this potential fix a try, follow the instructions below:
Part 1: Creating a Static IP
- Press Windows key + R to open up a Run dialog box. Next, type ‘control’ inside the text box and press Enter to open up the classic Control Panel interface.
- Next, use the search function in the top-right corner to search for ‘network’ then click on Network and Sharing Center from the list of results.
- Inside the Network and Sharing Center menu, click on Change adapter settings from the vertical menu on the left.
- Right-click on your Wi-Fi or Local Area Connection (depending on if you’re currently connected on a wired or wireless connection) and choose Properties from the context menu.
- Inside the Properties screen, access the Networking tab, then scroll down through the list of connections, select Internet Protocol Version 4 (TCP/IPv4) and then click on the Properties button.
- Inside the next screen, enable the toggle associated with Use the following IP address and set your own values.
- After you set the correct values, click Ok to save the changes, then move over to part 2 where we show you how to create a DMZ spot.
Note: If you don’t know which values to use, press Windows key + R to open up a Run dialog box. Inside, type ‘cmd’ and press Ctrl + Shift + Enter to open up an elevated CMD. At the UAC prompt, click Yes to grant administrative privileges.
Inside the elevated CMD prompt, type ‘ipconfig /all’ press Enter, then take note of the IPv4 Address, Subnet Mask and DNS Server. so you can paste them inside the Internet Protocol Version 4 (TCP/IPv4) Properties menu.
Part 2: Configuring a DMZ in Router Settings
- Open your default browser and ensure that your computer is currently connected to the same network that your router is maintaining.
- Inside the navigation bar, type the same IP address that you previously set as static and press Enter to access your router settings.
- If you previously established any custom credentials, insert them to gain access to your router settings. In case you haven’t searched online for the generic login credentials.
- Once you’re inside, click on the Advanced menu (Expert Settings) or whatever it’s called on your particular router model.
- Inside the Advanced model, click expand the menu named NAT Forwarding (or WAN Setup) and click on DMZ.
Note: Depending on your router model and it’s manufacturer, the name of these menus might be different. If you can’t find the equivalent DMZ menu on your router settings, search online for specific steps.
- Next, set the DMZ as the static IP address that you previously configured in Part 1, then enable DMZ functionality and save the changes.
- Restart your router, wait for internet access to ve re-established then connect your Magic Jack device and see if the problem is now fixed.
Method 4: Disabling MAC Filtering
If none of the fixes above have worked for you, chances are you are experiencing the 3002 Error code due to the fact that MAC Filtering (MAC Code Addressing Filter) is enabled in your router settings. In most cases, this problem is reported to occur with Belkin routers.
If you suspect that your router is currently configured to work with active MAC Filtering, you should be able to fix this problem by accessing your router settings and disabling this feature.
In case you’re unsure on how to do this, follow the instructions below:
- Open your default browser and paste one of the generic router addresses into the navigation bar and press Enter:
- At the login screen, insert your credentials or search online for the default username and password if you’ve never logged into this meu before.
- Once you’re inside, click on Advanced (Expert Menu) to reveal the Security menu.
- Next, click on the Security tab and click on IP & Mac Binding from the list of sub-items.
Note: The names of these settings will be different from manufacturer to manufacturer. You might also find this security option as MAC Filtering or MAC Addressing Filter.
- Inside the IP & MAC Binding menu, disable the option and save the changes.
- Restart your computer and your router, then see if the Magic Jack device is now working without triggering the 3002 Error code.
