The D-Link Dir-300 router cuts a lot of Wi-Fi speed from Dom.ru

Hi! I’ve been using dedicated internet since 2011, and a month ago I changed my tariff to 100 megabit, after which I noticed problems with speed and ping in the evenings, and also that the maximum I get is 20 megabits at best.

Router dlink dir-300nru (sort of), and the Internet itself is received USB – adapter 2011 year of purchase and also from dlink.

What can be the problem that the speed is reduced? Maybe it’s the router and the adapter?

I’m just thinking about which router to buy, and I don’t know what to choose.

ASUS RT-AC51U
ASUS RT-N56U
KEENETIC Air
KEENETIC extra II

But I think I’ll need to buy an adapter as well.

Can you recommend something?

Answer

Hi. In your case, I would advise you to solve the problem first. Find the reason why the speed is dropping.

You write that everything seems to have started after changing the tariff. I think it’s a coincidence.

First thing to do is check your ISP. Connect the internet directly to your computer. No router. Or through a router, but with cable. Check the speed (here’s the instructions). If as a result we get 100 Mbps or so, then the ISP has nothing to do with it. If we get 20 Mbps on the cable, we complain to the provider. What’s going on? Fix it.
Let’s assume that the speed is good on cable. Then there are two options: either the router cuts the speed or the adapter. It can be both. In any case, on Wi-Fi through D-Link DIR-300 you will not get 100 Mbps. But 20 is not enough. You need to check the speed on Wi-Fi from another device. Preferably with a phone, or a planet. If they will be low speed, I can only advise you to follow the recommendations in the article how to increase the speed of the Internet on wi-fi. Perhaps it will be possible to raise it a little.
If it turns out that on other devices the speed through the router is basically normal (50 Mbps and higher), then you need to do something with the adapter on your computer. Most likely replace it. Or maybe the reception is bad there, and that’s why the speed is reduced so much. You should check it right next to the router itself.

If nothing can be done, and the speed will still be low, and you have a desire to replace the equipment, then you can take any router from those you listed. All options are good.

But it is better, of course, to take a model with support for the 5 GHz range and the 802.11ac standard. There you can get all 100 Mbps over the air. These are all the listed models except ASUS RT-N56U.

As for the adapter, it should also support 802.11ac standard. And get one with antennas so that the reception will be better. Although, I don’t know how things are with reception. Maybe a router near your computer.

Do not forget that the speed depends very much on obstacles and interference (in the range of 5 GHz they are almost nonexistent compared to 2.4 GHz). You should also take into account the fact that in the 5 GHz range network coverage may be slightly less.

If you are interested, you can also read the article about choosing a router that does not cut the speed of Wi-Fi and gives 100 Mbps and more.
