Tried a couple of things. First, I used cross cable from the router to my laptop and got a good connection, also put that IP in ZA as exclusion. I could ping the IP from the laptop but could't get any sharing with the PC. Nor could I use IE to access the web.
Second, with wireless network re-connected and cross cable unhooked, I could share files, print, ping, but still cannot use IE to browse the web. I even tried to use the shared PCs IE but it would not go on-line from the laptop (works fine from the PC).
So with the present ZA exclusions I have for wireless, I have everything - sharing, printing, pinging, EXCEPT NO laptop web. I don't understand it - As soon as I had connected wireless earlier this week, I could browse the web, now it's gone... Noel
