how to fix issues with windows 8.1 pc wifi-limited

Day 6 since the problem began. I started having issues after a program installed incorrectly, uninstalled it & tried again-ending in another failure. I opened advanced SystemCare & cleaned registry, files, & used other tools-optimizing, cleaning, & fix small errors. After pc cleaned, I changed settings in my firewall (removed programs rules I no longer had). When my wifi started saying limited, I reset router, checked plugs/wires to ensure a good connection, the correct info (password & username) was being entered. Checked all other devices & they're connected. I made sure my wireless network adapter drive was enabled, working & updated. I disabled my wireless network adapter then enabled it again-command prompt. I tried every troubleshooting option given. I tried accessing restore points i had saved but the pc removed them & replaced them with restore points after I began experiencing issues. I tried doing a refresh but received a message saying I didn't have a system image on pc, & my usb media recovery wasn't working. the first thing I did after getting my laptop was create a system image backup & a usb recovery media, which leads me to the next thing I had tried. I put my usb in my laptop & tried using it for a refresh or restore, but it kept saying insert recovery media which was already inserted. I went ahead and used a restore point anyway, but it was unsuccessful & I tried 2 more times- each time being unsuccessful. I use my pc to work from home, I would appreciate it if someone could please help me fix this issue so I'm able to get back to work
