Just a general tip here. I was in the LG2 modem (the latest modem) and I was having sub par data speeds even in areas with good signal strength. Huawei E3231 Drivers For Dongle For Tv more. I tried PRL and profile updates to no avail. I tried last modem version before the current one which is LF9 and even at work where I am in a steel and concrete 'bunker' of a work place (lol), I am now getting good data speeds. And at home where I was barely getting LTE, I get decent data speeds considering Only about 20% of the LTE towers are in place here in the San Antonio area. I tried the original 'LEN' version modem, no improvement.

I'll try to explain my story & scenario the best I can so you can get a picture in your mind of what's going on here at home, or should I say what is not happening properly. As most of you are aware, the Galaxy S3 has wi-fi capabilities of 2.4 GHz & 5 GHz. My home router is the Netgear WNDR3700. I use both channels here at home (2.4 & the 5 GHz bands) for various components.2.4 GHz for my TV, Blu-Ray player, Wi-Fi thermostat, & a spare laptop. All four components can use the 5 GHz band, but the bandwidth rate is much better on the 2.4 GHz band because they are physically closer to the router, which is downstairs on the main floor. That's the way the 2.4 GHz channel works.the closer, the better & faster the connection is.

But I use the 5 GHz band for my main laptop & my GS3 as those devices are used primarily upstairs. I have better coverage & data rate with 5 GHz upstairs than I do on the main floor, even though I may be closer to the router when those devices are downstairs. I guess that's just the nature of the beast with 5 GHz. Software 3d Home Design Architect 2000 there.

But when I'm downstairs, the 2.4 connection is better than the 5 on my GS3. Flash Version 9 0 Plugin on this page. Oh, I have a 45/35 Mbps fiber optic connection here, in case you're wondering. So continuing. Let's say I come for the day & want to turn on Wi-Fi on my GS3. I do this because the 3G connection I have here at home is absolutely dismal! I'm lucky (even on a good day) to get.02 to.1 Mbps, but.now get this.I'm only two blocks away from the Sprint tower (yes, their own tower location maps shows this, & I've driven by there many times). I have 1 to 3 bars displaying at any given time, even this close.

Loading a text only page can take anywhere from say.30 seconds to several minutes. Forget about surfing the web here on 3G, it's impossible! I could try to load up my local RADAR image, go to the kitchen & make a sandwich, then come back & the page is still loading! On Wi-Fi, it's 'click', BOOM!

No wait time. Instant page load. But getting onto the issue here. Whenever I switch on Wi-Fi, it always. Always connects to the 2.4 band instead of the 5 band, which is what I need to take & use my GS3 upstairs. Running a speed test while on 5 GHz shows me a respectable speed of 90 to 95% of my bandwidth of 45/35 Mbps.

On 2.4 with the same speed test, it will show 20 to maybe 40% total bandwidth. Remember, the bandwidth is better upstairs on 5 than on 2.4. If I take the GS3 downstairs, the results are reversed. So.should I just tell my GS3 to 'forget' the 2.4 connection & use the 5 GHz band exclusively?

Or is there something I'm missing in the GS3 to 'prefer' to use the 5 GHz band over the 2.4 when I switch on Wi-Fi? It would be an extreme pain to type in the password for the 2.4 band to use it each time, as both channels on my router have a 63 character alpha-numeric, upper case-lower case ASCII letters password (if that's what you want to call it). It's a secure way to lock down my router, as it's not 'guessable'. Maybe I'm just making a mountain out of a mole hill, but it's something that really 'irks' me. I'm all ears & open to anything simpler than what I have now. Heres a few things to keep in mind. 2.4 vs 5 have different RF values.
