Iphone 5 wifi and 3G

[Samtb]

Is it normal to find that the iphone won't connect to weak wifi signals, only 1 or a few times even 2 cones? Is it also normal to find that 3G is very slow with anything less than 3 bars? I also find that indoors, there will only be 1-2 bars of network signal. Are these all normal and if not is it a carrier issue or an issue with the iphone?
