hey guys, so my laptop was able to connect to my house wifi for about a year but it suddenly it won't connect to the wifi. I brought my laptop to school and it's able to connect to wifi easily, but when I come back home i can't access the internet. all of my parents and sibling's devices are connected except mine. I ould troubleshoot the problem and it would work for like 5 seconds. On google it would say the DNS server couldn't be found or the network is changing and then it would say there is no internet access. please help, I need this computer to do school work and it's frustrating to do everything by hand when there are no resources available.

stuff I tried but didn't work:

netsh int ip reset c:\resetlog.txt <-- I did all of the netsh int ip options I don't remember the rest but they didn't work

ipconfig/release

ipconfig/renew

resetting network settings

restarting computer

manually connecting to wifi

Factory Reset

PC Refresh

updating network drivers on device manager

uninstalling antivirus programs

EDIT

so i am using the ethernet cable and the wifi is very fast. however, i need to use my laptop with wireless because my office is in the upstairs. is there anyway I could fix this???
 
Solution
If you have already gone into the network control panel and deleted the home network and then restarted, I would try changing the wireless MAC address using THIS free tool. It has worked for me on many difficult wireless connection situations.
