I have a personal laptop, a work laptop, and a cell phone, all of which have been connected to my Xfinity home wifi. About a week ago, my personal laptop stopped connecting to my home wifi and even showing my home wifi network on the list. I am still using my home network on my cell and on my other computer. I have also power-cycled the router; that isn't the issue either. I have downloaded all current wifi/connectivity drivers from Dell and Intel and rebooted my computer. I also told the computer to forget my wifi network and manually re-added it with my Xfinity security key, security type WPA2-Personal AES, and told it to connect automatically. My router has never showed up as a "device" on either computer, so that can't be the issue either. My computer can still connect to my cell phone (wifi tethering/mobile hotspot), and it still shows my neighbor's wifi on the available network list. Please, do you have any advice?
