Well it's so nice to see that someone else has been suffering from dropouts until SP2 was installed.
Prior to that my two XP machines suffered from constant drop outs and really annoyed me. I too was saying that wireless wasn't much cop if it didn't stay connected.
Since I put SP2 on and have a wireless ASUS router upstairs in the house (in UK) the performance has been superb.
I can sit in my warm living room and just surf away to my hearts content with only an occasional dropout - perhaps once an evening or so.
I am converted and would NEVER go back to wired networking unless I had no choice.
Brilliant. AND . . . a big thankyou to Microsoft for sorting out the wireless facilities in XP SP2.
They got it right.
