After the last OTA on my unrevoked Desire, my WIFI started to give me issues. It can only discover WIFI channels when I'm 2-3 metres away from the router, which is pathetic. And if i move away, the WIFI drops. I reset the phone back to factory default, and the WIFI works again as expected and not just when close to a wifi router. Thing is, i have a lot of things installed in my last rom (2.2 which i have nandroid backup using clockwordmod). Is there a way i continue to restore my last rom (which gave me wifi issue) and fix the wifi problem without starting from scratch again?
