I switched to windows 10 about 9 months ago and ever since my connection has been dropping in and out, It gets better when I reset my modem but even then it is slow, My network adaptor is Realtek PCIe GBE Family Controller, I am connected using ethernet through the power line but wifi with an external usb adaptor doesn't work either. Troubleshooting says Default gateway not available, it usually says not fixed, although once it randomly said fixed.
