I couldn't log on the net earlier, but I had a couple of times during the day.
It said "network couldn't recognize IP address".
So I try a few things still nothing.
Phoned my ISP's help desk thinking my router was shot or their network was down. After listening to Vivaldi's The Four Seasons for about an hour I finally get throught. 1st level support, they tell me to do all the thing's I have already tried and then rerun the set up cd, if that fails call 2nd level support.
Still nothing, called them, more of Nigel Kennedy. Back through the lot again ( learned a couple of new dos commands) still nothing. He said you have a virus or spy ware, which I know I didn't (PC get's a full scrub up at least once a week). 2 1/2 hours after a full wash down still nothing.
Then it came to me. I have my PC, two laptops and two PS3 all connected in to the router, but I grounded the kids and set it to one IP.
My son was upstairs on his PS3 (which I have noticed in the past, for some reason takes priority of IP addresses)
That was what was stopping me connecting downstairs. Problem solved.
Some help desk.
