My dad has Fujitsu laptop that is about 5 years old. No major problems. In the last year, he has had wifi connection problems in various hotels. Early simple diagnosis showed that it was either connected or not, no "limited connectivity" warnings. Long distance trouble shooting is not practical, but I tried. Oh, the issue happened to my mom as well, when she recently was in Germany with my dads borrowed laptop. My cousin (IT) in Germany even gave it a try without success.
We were all in Apsen and our condo has wireless and my dad and I both had our laptops. Most of the time, they were sitting next to each other. My laptop did not have a problem, but I was able to see that his was having issues. I played with it for a bit, but could not see a problem, other than thinking that the card may be bad...
We just ordered a new wifi and and I installed it last night. The laptop immediately saw the home wifi connection and connected. OK, it's the card.... Sooo, I take the laptop to their backyard and manually disconnect and try to connect. Nope, it sees the router, has 4 to 5 bars, but will not connect. I DL and install the drivers from Fujitsu's site and it connects. Back outside and same problem. The SW has an event viewer, so I watch what happens. When I am inside the house and within a certain radius from the router, the logs show a clean connection with handshake. If I walk right outside but leave the door open, it connects, but the handshakes do not happen. Step inside and it's all good.

Reading from bottom to top..
Look at lines 46-36. It shows the 'handshake' and that an IP has been given. Lines 17 to the top show show that it connects to 'Beech', but never does the handshake and subsequently drops the link and tries again.
For the record, I was able to duplicate this inside the house as well. Instead of walking out the door from where I was standing, I walked to the other corner of the room and the same thing happened. I don't think walls are an issue, as I was able to walk into a different room that has a lot of wall space between the laptop and the router.
I'm stumped, my laptop does not have this problem, granted, it has a newer wifi card (both are Intel).
Any ideas?
