I think this accounts for your speed test results. You are connected to the 2.4Ghz band using 802.11n (Wi-Fi 4) at a link speed between it and the router of 65Mbps. Your card is capable of working in the 5GHz band at the faster 802.11ac (Wi-Fi 5) at a link speed of up to 433Mbps.
So why aren't you connecting at that speed?
The initial decision is down to Windows/the network adapter as to which band it connects to. This should be based on the band with the best signal quality (mixture of signal strength & the amount of interference). The signal strength of your 2.4GHz band is a bit higher than the 5GHz one, once connected to the router, if band steering is enabled in there, it should then automatically try & move you over to the 5GHz band after a short while.
I would check the network adapter's properties to see if there is a Preferred Band option. To do this go into Device Manager expand Network adapters, right-click your network adapter & select Properties. Click on the Advanced tab & look in there. If you have such an option set it to 5GHz first.
I don't think we have investigated the physical location of your router, to see if signal strength can be improved a bit.
This is the best router location, but obviously, this is not always practical & a compromise has to be reached.
The general rule is to keep it away from:-
- Cordless phone (DECT) base stations
- TVs
- Loudspeakers & any sub-woofers (including those used with a PC)
- Computer monitors
- Electrical appliances – they often transmit their own signals that can interfere with Wi-Fi signals.
- Bluetooth devices – they operate on the same Wi-Fi frequency as your broadband, which can cause signal problems.
- Mirrors – they actually reflect Wi-Fi signals, stopping them from passing through walls and reflecting them back into the room.
- Anything containing large amounts of water – things like fish tanks and boilers can absorb Wi-Fi signals like a sponge.
- Large metal objects – radiators, for instance, will have the same effect on your Wi-Fi as mirrors. If you have a tower PC case with an internal WiFi card, the metal of the case can block signals to & from the antennae if they are located behind the tower case.
- If you are using a USB Wi-Fi adapter, use a USB socket on the front of the PC, as there is more open space around it than at the rear. If a USB extension cable is used, try to ensure that it is fairly short, so as the power from the computer is not attenuated. Long extension cables can cause the adapter to not have enough power from the computer to work correctly.
As a very general rule, the signal travels best on the same floor as the router and to the floor below. It does not always propagate very well to a floor above the router. However, with more modern routers, if they have a higher specification, they may be able to get the signal upstairs OK, but your ability to receive it also depends on your device's network adapter being of a higher specification, as well as its age.
