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 !

enjoy 😉
