Wireless adapter being the Netgear USB A6150 model - correct?
"Sometimes(and at the current moment) it wont even detect any 5ghz networks."
Meaning that sometimes the computer is able to connect using 5 GHz?
Make and model router, make and model wireless adapter (if not the above mentioned Netgear USB adapter), how far away is the router, and what (walls, furniture, floors) are between the router and the problem computer?
My immediate suggestion is to obtain a USB extension cord. Plug the wireless USB adapter into the extension cord and the extension cord into the host computer.
The extension cord should permit you to raise the wireless USB adapter up and about. Away from the computer and to a position that will facilitate improved reception and transmission.
May only require a few feet to improve connectivity.
Also note if the adapter is getting overly warm or hot. Generally a sign that failure is occuring.
let me clarify:
for the first 3 hours, the computer was able to connect itself to the 5ghz wifi. I, unhappy with the ping i used to get, changed to 2.4ghz and then back to 5ghz, and it stopped being able to detect 5ghz networks(it says "no wi-fi networks found"). I changed something (dont remember what) and it detected networks, but i got "cant connect to this network" while connecting. I left my computer to idle for 5 hours, and it is now detecting the network once again. I still cant connect though.
yes, i do use the adapter you said.
im around 6 meters away from the wifi, and there is only a glass door which is open most of the time. I dont think distance is a problem since when it worked, I used to get around 55 mbps, that is a lot more than the 3mbps i get with 2.4, and the high package loss and ping. Also i bought the adapter literally today
EDIT: forgot to add the router. it is made by sercomm, and is called smart modem by tim. i doubt you will come across documentation in english though.
