As far as I can see, this seems to have started to occur within the last week... 2 computers on LAN: desktop and laptop. Both using wired (gigabit ethernet) connections My little network icon in the system tray often goes to a yellow ! exclamation mark, sometimes a red X (it seems to happen mostly upon initial logging into Windows after booting up) Clicking troubleshooting says to check the router. My 2 computers can see each OTHER fine when this happens - I can view shared folders and copy files fine between them. But NO internet access when this problem occurs. I can still access the router's admin pages via 192.168.0.1 Cannot ping anything on internet - says no route to host. This problem started occurring on both computer roughly over the last week. (It's Sep.20/2015 as of typing this right now). I noticed both computers did a large batch of Windows Update updates (like 20+ on each!) a couple days ago. OS on both: Win7 Home Premium Has there been a Windows 7 update recently that has made this a common problem with people? My network drivers are up to date. I have not changed any config on my router or on either of the 2 computers recently (not even remotely recently). This is very important as I'm not a person who uses the computer infrequently to go on YouTube and watch funny cat videos - my desktop here is what I do all my work on: banking, work emails, other important things on the web, etc, etc. Suggestions? Thank you SO much in advance for any help!!
