WIFI signal is very weak but strong right next to router
i have a iPad 2 wifi 16gb model.
The wifi is very weak, 1 bar, but if i move it right next to the router then i get 4 bar, if i move it just 10 cm away from router then its 1bar again.
I have removed the wifi board and replaced it with a known good board but it is still the same.
I have replaced the wifi cable/antenna but no go.
It is not a software problem, it is not a router problem, it is a hardware problem on the logic board but am lost as to where to look next, i have removed all the covers and checked under a microscope but cant find any corrosion or damage anywhere.
I have repaired many iPads but this one has got me flummoxed and electronics is not my forte so at this point i am truly discombobulated.
If ever i needed an "oldturkey03" at christmas its now.
