I gave up on the WIFI issue after troubleshooting it from so many different angles. I am just too lazy to call Samsung and get a replacement shipped out. It happens with stock Eclair DI18 and with Froyo DK28. I had it fixed for a while once after updating Profile/PRL, but then when I flashed to Froyo it appeared again. Its such an odd problem, at least for me. It seems too buggy and as a result just too difficult to isolate. (I just got done reading the last 10 pages of the forum to see what people had to say regarding the WIFI issue, I do not believe wiping clean will fix it as I have done that 6-7 times now).
