fixed : Nokia glass fiber modem all lights flashing but no internet

Question :
I have no internet signal on my Nokia XS-2426G-B glass fiber modem. Only the power light was flashing when I first discovered the problem. So I restarted the modem by taking out the power cable for at least 30 seconds and plugged it back in, but that did not resolve the problem. Now, all lights are flashing, and they keep flashing, there’s no progression in any way… Trying yet another restart by temprotarily disconnecting the power doesn’t change anything… All light keep flashing and noting happens, the internet doesn’t come back on…

What can I do ?


Answer :

The flashing of all lights indicates that the power adapter is broken. The obvious way to fis this is by contacting your glass fiber internet provider and asking for a power adapter replacement. But that will resolve your problem very quickly, as it will take a few days for you to receive the part, and that isn’t going to get you back online as soon as possible…

The quickest way to fix this is to find another power adapter with similar specs and get your modem the power it needs to reconnect to the internet.

The specs for the power adapter are :
output : 12V DC 3A
connector : 5.5 * 2.5mm tip (tube shaped)
polarity : inner centre positive (+) and negative (-) on the outside

So to resolve your problem, do this :
-1- contact your glass fiber internet provider and order a new (original) power adapter ; ask how long it will take for you to receive it and choose one of the following to save you in the mean time :
-2A- see if you have a 12V DC adapter with a 5.5 * 2.5mm inner centre posisitve tip and at least 3.0A lying around that you can temporarily use
-2B- if you don’t have one lying around and you need to get back online a.s.a.p., go to your local electronics shop or DIY shop or hardware store and get yourself a universal 12V DC power adapter that can be adjusted to 3.0A and can be fitted with a 5.5 * 2.5mm inner centre positive tip
-2C- if you can do without cabled internet (e.g. because you can do with 5G mobile telephone internet) for about 24 hours and you want a cheaper 12V DC power adapter, buy one online with overnight delivery and make sure it meets the above mentioned specs.

On Amazon you can get several power adapters that will do the job :
[ we get a fee if you buy on amazon using these links ]
on amazon.com : multi-purpose 12V DC Power Adapter max 3A
on amazon.co.uk : multi-purpose 12V DC Power Adapter max 3A
on amazon.de : multi-purpose 12V DC Power Adapter max 3A

So, once you receive the official/original power adapter from your glass fiber internet provider you can use that one, and you can keep the other adapter as a spare in case of emergency.

That’s it !

fixed : error message -2101F when trying to reinstall macOS

Question :
I have a 2019 MacBook Air and when I tried to install the latest macOS system update, it froze… I called Apple, and they told met to reinstall macOS, but evert time I turn my Mac off and back on with the OPTION+SHIFT+R key-combo pressed on my keyboard, I run into a black screen with a light grey globe with a white triangle with an exclamation mark in it (a warning icon) and a text below it that just says “support.apple.com/mac/startup -2101F”

What can I do to fix this ?

Answer :
The -2101F error message that you are getting means “cannot connect to the internet”, and connection to the internet is essential for your Mac to do a regular reinstallation of macOS nowadays…
There are some options to solve this problem. First try this one :
– check if your WiFi internet is working properly by connecting to your WiFi using your iPhone (or any other mobile phone)
– if it turns out that your WiFi is not functioning properly, restart your modem to make sure all lights on it (like “Power”, “Internet”, “LAN” end “WiFi”) start blinking
– then restart your Mac and try to initiate the reinstallation process again

If that didn’t help, try this :
– connect your Mac to the internet using a UTP/Ethernet-cable
– for this, you need a UTP/Ethernet cable that is has connection to your modem (preferably directly)
if you buy anything from Amazon by using the links below, MacManus.nl makes a tiny profit, but it will not affect the price you pay
– if you don’t have a UTP/Ethernet-cable, you can borrow one or buy one
to buy one from Amazon US, click here
to buy one form Amazon UK, click here
to buy one from Amazon DE, clcik here
– modern MacBooks don’t have a dedicated UTP/Ethernet-port, so you will need a UTP/Ethernet-to-USB(-C)-converter-cable also
– if you don’t have a UTP/Ethernet-to-USB-C-converter, you can borrow or buy one
to buy one from Amazon US, click here
to buy one form Amazon UK, click here
to buy one from Amazon DE, clcik here
– if you have a UTP/Ethernet-to-USB-converter-cable, but you only have USB-C ports on your Mac, you will need a USB-C-to-USB-converter also
to buy one from Amazon US, click here
to buy one form Amazon UK, click here
to buy one from Amazon DE, clcik here
– after you have connected your Mac to the internet using a UTP/Ethernet-cable, restart your Mac and try to initiate the reinstallation process again

If that didn’t work, try this :
– connect the UTP/Ethernet-to-USB(-C)-converter-cable to a different port on your Mac, because sometimes that USB/USB-C port on your Mac may be faulty, misfunctioning of broken
– then restart your Mac and try to initiate the installation process again

If that didn’t work, try this :
– make sure that one of the USB(-C) ports on your Mac is functioning properly by connecting a USB-mouse or USB-keyboard or USB-stick with a light in it (you might also need a USB-C-to-USB-converter-cable for this) and check if the light is switching on
– if the light in the mouse, keyboard or USB-stick doesn’t turn on when connected to your Mac (do make sure that the light is actually working when using it on another computer), your USB-port is broken and you will need a hardware repair (or a new Mac, which might be more tempting in a lot of cases)
– if the light does turn on, disconnect the mouse, keyboard or USB-stick and use that USB(-C)- port for the reinstallation of macOS from a USB-stick
– first you will have to create a USB-stick with a macOS-installer, to do this, you will need another Mac that is the same age or newer than your Mac and if your Mac doesn’t have an M1/M2/M3-or-newer processor, you will need an Intel-based Mac for this
– follow the directions to create a USB-stick with a macOS-installer that are outlined here :
https://www.macworld.com/article/671308/how-to-create-a-bootable-usb-macos-installer.html
or the instructions from Apple itself :
https://support.apple.com/en-us/101578
– if you don’t have an empty USB-stick at hand, you’re best of buying a 32GB USB-C-stick
to buy one from Amazon US, click here
to buy one form Amazon UK, click here
to buy one from Amazon DE, clcik here
– after you have created the USB-stick with the macOS-installer on it (on the other Mac), plug the USB-stick into your faulty Mac (make sure you use the USB(-C)-port that you know is working) and restart your Mac and initiate the installation process

That’s it !

fixed : no internet connection while WiFi and LAN are okay (after running Jaksta)

Question :
I was running an app (Jaksta Media Recorder) that crashed. Now I am no longer able to make any connection to the internet from macOS using my regular settings. Safari, Apple Mail.app and Whatsapp for macOS can no longer get propper connection to the internet.
I have tried resetting my internet modem, and my VPN now works, but the apps still cannot get a propper internet connection… so it appears to be a DNS problem, but changing DNS servers didn’t help…

What can I do to solve this ?


Answer :
As you might have expected, Jaksta Media Recorder has caused this problem when it crashed… to fix it, do this :
– restart your Mac
– do not startup any apps, startup the Jaksta Media Recorder app first
– when the Jaksta Media Recorder window opens (where you can see your previous downloads a.k.a. recordings) go to the bottom left corner and put the slider (that is turned ON automatically) in the OFF position
– then quit the Jaksta Media Recorder app

That’s it !

enjoy πŸ˜‰

Note : Jaksta Media Recorder for Mac is no longer being supported, as of 2023 Jaksta is a Windows-only app, so if you run into any problems with Jaksta for Mac you are pretty much left hanging… so, if you’re looking fro an alternative for Jaksta, see this post :
fixed : current version (or replacement) for Jaksta downloader app on macOS

fixed : Nintendo Switch can’t see iPhone’s Personal Hotspot

Question :

I am on holiday and since there is no WiFi-internet here, I would like to connect my Nintendo Switch to my iPhone’s unlimited internet plan by connecting to it’s WiFi using the Personal Hotspot feature in iOS. But if I have Personal Hotspot turned on, my Switch can’t see it… even if I can connect to the Personal Hotspot from another iPhone.

What is wrong ?

Answer :

There’s an easy fix for this :

  • on you iPhone, goto the Settings.app
  • in the Settings window that opens, click on “Personal Hotspot” (should be just below “Mobile Data” – if it is not, your mobile phone provider has blocked this and you have no way of wirelessly sharing your iPhone’s internet connection)
  • in the Personal Hotspot window that opens, set the “Allow Others to Join” slider to ON
  • you can just use automatically generated WiFi password for your Personal Hotspot, but if you want to set your own password, click on the triangular arrow right next to the password and a new page wil openen where you will be able to set the password of your liking
  • now, the one crucial step : set the “Maximise Compatibility” slider to ON
  • then exit the Settings.app
  • goto your Nintendo Switch and now you will see your iPhone’s personal hotspot listed as an available network

That’s it !
