Recycled cable modem, router and same. In a hour it worked all on its own. The ISP was at fault. Lesson? Don't fix your PC, call the ISP.
hello! I know, that this question has already been asked many times, but i still cannot find something that works. I've tried everything-deleting c/temp files, cmd prompt ipconfig/release ipconfig/renew , network sharing center enable/disable wifi, deleting LAN card - they work for 10 to 15 mins and then i lose the access again. Please help me! I would be very grateful!
