For the past couple of weeks, sometimes I've had trouble connecting to the 2.4ghz on my quantum router. The network name shows when I search for wifi networks but when i try to connect it doesn't allow me to. the 5ghz one works fine. If i log into the router settings and change the channel i can then connect, but after a while (sometimes a couple of days, sometimes a couple of weeks) the same thing happens and I have to change the channel again to get it to connect. I don't know why I can see the network but have a problem connecting. it happens on all the devices that I use.
any help would be appreciated
