Ever since I switched to Verizon FIOS from Verizon DSL a year or so ago, I've had an intermittent problem on my Windows 7 desktop machine where the system boots with no internet access and the ncsi icon in the taskbar showing a caution sign. The same system never exhibited this problem with the old DSL router. The computer is connected via ethernet (not wireless). The problem seems to occur on about 10% of system reboots.
Some googling has come up with the solution to disable and then immediately re-enable the network connection, which does seem to do the job. However, I don't want to have to keep doing this. More searching came up with this solution, but this states that it is for Vista only and Win 7 should not have the same problem. I made the change anyway, and have not had the problem since, but I just did it yesterday.
Any ideas how to troubleshoot and fix this issue?
Does the internet work even when you have the caution sign? – uSlackr – 2012-02-02T21:23:39.920
No. No internet access when the caution sign is displayed. – PIntag – 2012-02-02T21:33:48.393
