I have modded a friends apad a bit because he asked for it haha. He complainsthat his wifi reception is poorer than most of the Filipinos. First step was to build a brand spanking new internal antenna and solder it to the existing flat wire antenna. His wifi reception is very bad even when his sitting 3 meters away from a router, there was only one little bar.
First thing I did was to calculate for a new band of antenna, what i really did was solder a shielded wire but please, don't tell him haha
heres what it looks like
Pretty neat huh?
Now he's got 3 bars and lived happily ever after lunch.
