Upgrade my old D-Link DI-524?

[Thitn]

Hello,

I dont know anything about modems/routers but I know that my router is fairly old.
Its a D-Link D-524 from 2004/2008. Its connected to a b-box2 modem (the free modem my ISP gives me, which is Belgacom in Belgium)
My internet speeds are pretty slow, downloading stays mostly below 1 mb/s. I feel like I should be getting a higher download speed.

Should I upgrade my router, and should I try and get a better modem too?
Will I see an improvement knowing that my PC is connected to the router with a cable and not wireless? But I do use the same router on all my wireless devices.

If theres any more information needed, let me know.

ADSL, wireless or fibre cable internet?

Internet plan DL and UL speeds?

It's ADSL.

Should be atleast 50 Mbps - 70 Mbps download and, 4 Mbps - 6 Mbps upload.

Maybe you got what I've got - it goes through a crappy phone exchange that can't put out more than 9mbs and by the time it gets to the house its less than that.

But I still updated my modem/router to a Netgear DGND3700 - N900 dual band wifi. It suits my family. We got mainly 2 PCs and a laptop. My PC is connected by ethernet. The laptop by 2.4GHz wifi and my son's PC by 5GHz wifi. We also got 2 smart TVs and can run movies to them over the wifi from our PCs.

Our download speed varies from 3 to 6 mbs.
