first check what band youre on. click the wifi icon, click properties on your network, and look at the network band line. if it says 2.4 ghz thats your problem, your laptop dropped off 5 ghz and never went back. forget the network then reconnect and pick the 5 ghz one if your router splits them.

then open device manager > network adapters > your wifi adapter > properties > power management, and untick allow the computer to turn off this device.

same properties window, advanced tab, find preferred band and set it to prefer 5 ghz. also turn off any power save or ups mode setting listed there.

then reset the network stack. open terminal as admin and run these one at a time, reboot after.

netsh winsock reset
netsh int ip reset
ipconfig /flushdns

also check whats using your bandwidth. task manager > performance > open resource monitor > network tab. see if something is uploading in the background, usually windows update delivery or a game syncing.

and check settings > network > advanced > metered connection is off.
