For the past few days, EXCLUDING today, My computer loses internet connectivity. In the system tray a warning appears and REPAIR may or may not work. Also when I try to search the results page does not come up nor does any web site. In addition my mail client icon starts to MOVE as opposed to being STEADY until an email comes in when it FLASHES. All indicators that I need to reboot. This solves the issue until it reappears. EXCEPT today. I have been using this tower for several hours with no issue. Is it possible that my ISP had intermittent issues at THEIR end? Rebooting the modem and router was never an issue. It was always rebooting the tower that fixed the issue. Any insight would be welcome. At one point I installed a net card assuming the on board connection had an issue. I have not reconnected the on board yet. If the issue returns I will try that.
