    Hello, I have a question about my router. Today I have a 300Mbps optical fiber. I bought this router especially so that I could use Wi-Fi with at least 200 Mbit (The packaging from the router says that the speed is 450 Mbps). After connecting, I have 90 Mbps on wi-fi. And now the question is whether this is the fault of the company that provides me with the Internet, or maybe this router does not really reach this speed of up to 450Mbps. (I have a good wi-fi network card in my computer for usb up to 300Mbps).

    Card in full N, router with 450Mb / s LAN / WAN 100Mb / s and at 2.4GHz 90Mb / s speed, which is all right and even very good.

    So it's the supplier's fault? Is everything ok with the router? The WAN port somehow does not limit the speed I should have (300Mbps)?

    No, the provider gives 200Mb / s but the router has a WAN of 100Mb / s. It is good but not for this link, needed with the 1Gb / s switch. It is this port that determines the speed also after WiFi. When it comes to WiFi, on the 300Mb / s N card you will achieve a maximum of about 100-120Mb / s, on a 450Mb / s router maybe around 150Mb / s, but this is under ideal conditions and with a router. You want to have a certain 200MB / s, you buy a router with WAN, LAN 1GB / s and you connect the computer with a LAN cable.

    Overall, it's probably one of the better routers, but:

    It limits because it is only 100 Mb / s. However, the 450 or 300 Mb / s for Wi-Fi is still unattainable. In practice, up to 30-40% of this is achieved, so with this card it will be something like 100 Mb / s

    As for WiFi, I can add something like this:

    rt-ac1200g +

    2.4GHz: approx. 2m
    DL "201.01" UL "158.60"
    DL "213.71" UL "159.64"

    5GHz: approx. 2m
    DL "357.74" UL "221.03"
    DL "349.84" UL "221.56"

    INTEL(R) DUAL BAND WIRELESS-AC 7265

    And if I just bought a router with a faster WAN? Would it then be faster? And how could someone give me a suggestion of a good router with some faster WAN? It's best that I could buy such a router from a stationary saturn store, because I wanted to take it home for a test, and if it would work with higher speed, I would leave it for myself. (I mainly want the WI-FI to be as fast as possible because the router is in such a place that it would be difficult for me to connect to the computer with a cable.)

    Real 200-300 Mb / s? It must be a router with Wi-Fi in the 2.4 / 5 GHz aa standard, but then the network card must be ac. Also remember that walls will be a problem, because the 5 GHz band passes through walls and other obstacles much worse. The WAN entry alone will not do the trick.
  • Network and Internet specialist
    How much will you achieve with the N300Mb / s card has already been written on the computer. A router with a Gigabit switch will not change that. A question about the budget? the mentioned Asus AC-1200 is 250-300 PLN. in general, it pays to buy equipment with 1Gb / s and WiFi in AC.

    How would I have these devices? Router -> https://www.morele.net/router-tp-link-archer-c1200-1020021/ Wi-Fi card -> https://www.morele.net/karta-sieciowa-tp-link -ac600-archer-t2uh-701788 /. It would be better?

    Router OK but card is only 600Mbps AC, mainly based on 5GHz. It is difficult to judge how it will match you with the router and whether it will give 200Mb / s WiFi. I have an AC 1200 router with Gigabit, but I connect all devices that require high speed and gigabit LAN cards with a cable. After LAN, I calmly pull 600-700Mb / s in communication between these devices. And I use WiFi for mobile and laptop, although the house and neighbors are about 10m away from it, so the air is clean.

    Solved this case, so the problems were 2 one is a router that should be 5GHz with a WAN input of 1000mbps. The second thing is a damaged twisted pair cable. After the replacement, everything worked fine.
