Interesting Wifi Problem

Hey Guys! I hope you can help me!

So upfront: I am currently living in a Hotel because of work, so I dont have any access to the router nor can change its position.

Now to the problem:

I like to game in my freetime, so I brought my PC along. The only mean to connect it to the internet is via the Wifi of the hotel. As many of you know, to play competitive online games you need to have a low ping, and a low packetloss. The Wifi of the Hotel is sending signals in both the 2,4 Ghz and the 5,0 Ghz frequency. When I connect to the 5,0 Ghz network I usually have a low signal strengh, but an extremely low ping and flat 0% Packetloss. The 2,4 Ghz network on the other hand has an extremely high signal strengt, but because of interfereing networks and devices (i think) the packetloss of outgoing data peaks to 10% a lot of the time, needless to say it is not at all suitable to play any games.

So a few days ago there was a change in the network.

While before my PC would show me 2 Networks (HotelXXX2,4Ghz and HotelXXX5,0Ghz) it now only shows one network, that is HotelXXX. If I connect to this network and I look into the status of the connection it always shows me that I am connected via 2,4Ghz (it presumably automatically connects me with the 2,4Ghz version, because the signal is stronger). Today I checked my surroundings with "Acrylic Wifi Professional" and indeed, it shows me 3 Networks with the Name "HotelXXX", 2 on the 2,4Ghz frequency, and one on 5,0Ghz. And indeed, if I bring my laptop near the router I get a connection to the 5,0Ghz network. My Question is now: Is there a way for me to make my PC ignore the 2,4Ghz frequency completely so I always get connected to the 5,0 Ghz network? Of ist is possible to connect to a specific wifi via only the mac-adress (because the 5,0Ghz network has a different one than the 2,4Ghz)?

I am thankful for any help or suggestion I get!
