    Galaxy S4 - Samsung Wireless Signal Booster

    Hi All - I searched the forum and couldn't find anything on this topic - my apologies if I missed something. I just got a Galaxy S4 (switched from iPhone). The signal strengh is very weak in my house - mostly because my downstairs is underground. I puchased a Samsung Wireless Signal Booster (runs calls through my internet? not a techie - but think that's right). It worked great with my iPhone - but doesn't seem to do much for my new Galaxy - I tried resetting the wireless booster - and I also downloaded a signal booster app on the phone - still seems to only show 1-2 bars - with spikes to full bars sporadically - then back to 1-2 bars. Any suggestions? Thanks!

    Need more info. Where can we get some on that device?

    Was your iPhone LTE? If not, then you are probably on a completely different network.

    The S4 will be looking for an LTE network first, then fallback to an HSPA+ network, followed by EDGE, GPRS....

    Hi Beer Goggles - thank you for your response. I think I got this figured out - but would appreciate any additional direction you could provide (or confirm I'm correct in my findings) - I noticed that my phone says 'wireless extender' when I'm at home - when at work - it says 'verizon wireless'. I also used the info below and dialed #48 to see if I was on the network extender - it says I am - and provides some code. I also checked settings and signal strength was between -73 and -75 dBm at home - at work it's -87dBm. I'm not sure what is 'good' based on these numbers - but assume the 'higher negative' is the better? The blue lights are on and solid on the network extender. I 'assume' that the signal strength bar isn't representing my true signal strength at home because it's running through my internet? That would explain why the bars jump around so much at home. Below is the network extender detail. Thanks again for your help - I'm new to forums and you guys are giving me much better info and help than I get from any customer service number I call.

    Below is to the guide - but not sure if you have to go through the link above to get to this one.

    That is incorrect, higher numbers mean a better signal. -70 is 10 times stronger than -80

    Firstly, remove any "signal booster" apps, they are all nonsense.

    Secondly, in the -70 to -80 dBm range you should be getting 5 bars easily.

    I'm at home on LTE with -94 dBm and I'm at 4 bars.

    What type of network does the extender appear to be? LTE? HSPA+?

    Hi BG - sorry it's taken me so long to reply - crazy week - I cannot find anything on the device or in the user's guide that gives the 'type of network' - I found one reference to EVDO - but only in reference to trademark/copyright. I'm at the office now - signal is -84 dBm 56 asu; and I have four bars. At home it's running anywhere between -73 and -93 with 1 bar - sometimes jumps to 4 bars briefly. I am on the network extender - according to the device itself - as well as when I dial #48. I haven't done enough testing to know if I'm going to drop calls - I'll try that next. Question - should the bars be high if the signal is run through the network extender? On my iPhone - they were - but maybe that's not the case with the S4...maybe network extender signal strength has to do with the wi-fi/internet connection? Thanks agian for your help.

    The booster may be only a 3G booster and not helping 4g lte.

    My 2 cents

    Is it just me or do they only boost the signal they receive?

    I'm not sure what you mean.

    They act as a mini cell tower and their "backhaul" is the Internet.

    Are you asking if it's a repeater or relay?

    the guide has a whole section for radio waves so comparing dbm is better then comparing bars. it also says that you can have a maximum of 3 devices, and each connection slows everyone down. the antenna is also important.
