How to Wifi works better w cp and tablet..

Did you update your bios, which is recommended, before "updating" to windows 10? HP probably doesn't support your device after w10 update.

It may be just one of many w-10 bugs.

If restarting helps temporarily it could be a number of things software related, virus, orphaned bit of code. I would check the dongle that you got to make sure it works on another computer and if it's ok then you have eliminated hardware as your problem. It might then be possible to track down what starts running that is not there immediately at startup. I have a cannon printer that I use wired because it screws things up if connected wifi.

How much and how valuable is what you have on this computer? Can you back up what is important and do a windows 10 clean install? I have a 5 year old Dell laptop that came with Ubuntu which I later installed windows 7 on and when I "upgraded" to w-10 I went to Dell and updated the bios and I tried to install w-10 with the "update" and it was noticeably slow laggy and erratic. I downloaded Microsoft media creator for windows 10 and plugged the flash drive in and a notice popped up that it appeared that I had tried to update to windows 10 and it asked me if I would like to recover but with the warning that I would not be able to return to windows 7. I had the important stuff backed up and I could always wipe the drive and return to windows 7 so I let it go ahead and it fixed things. Still not as good as windows 7 but as good as I have seen w-10 run on anyone else's computer. If you can back up and recover, it might be worth a try.

 

Try deleting your browsing history, it can fill up fast on older models without much RAM.

 

I just now hooked up a 3m ethernet cable and it seems to be working much better. I don't know what that means overall but we'll see if that improvement lasts

Edit: Wow much faster. Better than ever. I ordered longer cable from China already
