need help to fix my wifi - no network available

good day to you

modem firmware 04.05.04_G

thats my iphone info
please someone i must have the wifi fix soon
i don't know what to do
i downloaded to 1.1.4 and even to 1.02 and it's the same
now i'm back to 2.2

thanks

check the link in my signature.

i will try do it again

i've tried to do it but still the same
i have no wifi network in 1.1.4 and in 2.2
i think the problem is with the mac address
i saw in some forum that the mac address and the bluetoote need to be the same with one digit below each other or something
and in my iphone there totally different
i don't know what else to do

The forum you saw that on i.e. the wi/fi and the bluetooth have to be the same except for the last digit also documents how to revert back to your orignal address.
The problem is being blamed on zipphone though Ive used it a lot and never had it change my wifi address.

Wifi support on the iphone is pretty sketchy.
And if you want it fixed quick and dirty vs spending over 1 month playing with it. Just bit the bullet and get a new com board for 80$

Every single person with a problem wifi has had it resolved without fail by replacing the com board.

I suspect its a either a hardware issue or a Nvram corruption issue.
If geting a new com board dont fix it then it just may be worth geting another phone. (Which is the route Im taking).

This is what I recomend for most wifi issue guys.
a. Make sure you revert to your orignal wifi address
b. Dont bother with the going down to 1.1.4 and back up again thats a complete waste of time circus.
c. Open your phone clean / unscrew the two screws above the com board and press down again.
d. THe back of your iphone will have 5 white square on it. Make sure these are isolated if not put some tape on it.
