My wifi antenna is not picking up a signal very well, i lose wifi if I am more than 20 ft from router. The code to get into service mode doesn't work on my galaxy s4 model SCH-I545, nor do any of the codes for that matter. Suggestions?

Nothing wrong with your antenna - device is susceptible to frequency interference.. not enough insulations involved in "non-Apple products" casing so it gets detered by magnetic waves , heat variations and signal parameters . Your best solution apart from getting a new phone or new wifi AP device would be to remove physical interference between the two communication points . Meaning if your connected to a wifi - ensure there is little (or if you know your $@$* you could angle other antennas to boost the range parameter) electronics along your line of sight and definitely no aluminum objects places between this path (line of sight-physical distance between you and your router/satellite or Arial) and hope your signal is enhanced .

Do the same with regards to cellular ,locate the nearest cell tower and point your device in that direction -finding the clearest path ahead (no walls and stuff)

If you are on a newer update that won't work. I'm running the 4.4.2 update and they don't work.

A factory reset, also known as master reset, is a software restore of an electronic device to its original system state by erasing all of the information stored on the device in an attempt to restore the device's software to its original manufacturer settings

So do you know how to do this without errors..

By hard booting *you'll have access to a regular filesystem menu, in which a factory reset should be displayed as an option . That is the only safe method (You doing it) trusting apps and programs to do it for you won't result in 100℅ successfully wiped device .

As far as I can recall the method used for Samsung devices would be to hold the volume down+power+home button (all 3) continuously whilst rebooting .
