I have just got my desire on T-Mobile, and am happy with the phone. But the signal strength both on my wifi and phone signal is very week. I was originally on T-Mobile for many years and never had a signal problem at home, so I tried my sim in an old Nokia and I am getting full bars, in my desire it fluctuates between 1-3 bars. I also have an N-router set up and get perfect coverage right across the house with all my wifi devices, but not the desire, even if I am only a few feet away from my router the best I can get is about 50% strength. Is there a problem with the firmware, or do I have hardware issue, any comments welcome.
