Hi Guys,
i have a short question.
at home i have the option between 5GHz and 2.4 GHz wifi with my ASUS router.
my question, does the 5GHz Wifi on my galaxy s4 consume (significantly) more battery than the 2.4GHz WiFi?
i do not really need the 5GHz WiFi for my mobile device at home. so if the power comsumption would be much more than on the 2.4GHz of course i would just use the 2.4GHz frequency.

...really? Anandtech says that the Prime has a Broadcom controller capable of 2.4 GHz and 5 GHz but that the Prime only works at 2.4 GHz. Why is this? Is this a hardware imposed limitation or can it be changed via software? My 5 GHz WLAN at home is screaming and interference-free whereas my 2.4 GHz WLAN is being thrashed by my wireless IP cams and there are lots of neighboring APs on that band. It won't stop me from buying the Prime but really ASUS? Why limit it? My POS Atrix 4G connects to my 5 GHz WLAN.
I was dissapointed in finding this out too. I doubt it could be made to work since the wifi antenna would need to be created for the 5.8ghz band and most likely, connected to the 5.8ghz portion of the chip.
AFAIK, the only dual-band Android tabs are the OG Xoom and the Samsung GT 10/8.9/7+. Everything else is b/g/n only. The Moto Xoom 2 (aka XYBoard) tabs should be dual-band as well. Yes, I'm keeping track since I have a dual-band setup.
For DYI'ers, you can try replacing the built-in antenna with a dual-band PIF antenna. The antenna pigtail (cable) uses a U.FL connector, so no soldering needed. I have some pulls from a busted Cisco router. Probably won't work, since supporting chips (RF amps, etc) for 5GHz band are probably missing, but couldn't hurt to try.
Anandtech and CNET both reported severe issues with WiFi connectivity. Is this something we should be concerned about?

It's already known they both got deffective units.
About the antenna, the first thing i read in the specifications of the tablet was that it would only connect to 2.4GHz, so it was there since day one.
Wow, I didn't realize this... This might actually be a deal-breaker for me, since the 2.4GHz freq is so saturated around my house and inside, I pretty much have to run on 5GHz. Why in the world would you exclude 5GHz... This totally blows.
how would this affect my daily usage?
the hardware supports 5GHz, but Asus disable it in the software for battery life reason.

It most likely won't affect most people at all.

The interesting bits were about wifi performance:
"The original Transformer was made out of plastic, through which RF travels quite nicely. The Prime's metal construction makes things a bit more finicky. Indeed this is exactly what I saw, where depending on tablet and AP orientation I'd see anywhere between 10Mbps and 36Mbps downstream (average speed tended to be in the 15 - 20Mbps range)."
"TF Prime's WiFi performance is far more sensitive to orientation to the AP when compared to the original Transformer."
Just going to have to wait for devs to hack the wifi module.

This has affected me severely. I have tried everything to use my Prime with Bluetooth headphones for watching Netflix. Without Bluetooth streaming, I get about 17000kbps download speeds. With Bluetooth streaming, that drops to under 1000kbps, making Netflix buffer constantly. 5GHz connectivity would solve this problem right away. I'm very disappointed that they would exclude this basic functionality.
wait the prime doesnt support 5ghz networks....
Hi Guy's,
Does anyone have any idea how to improve the wifi strength?
I am using a BT homehub 3 wireless N router and all of my other devices (laptops, iPod Touch, ZTE Blade etc) are able to pick up wifi ins ome areas of my flat and my viewpad will show no signal. My router broadcasts all of the wireless type at the same time and I have tried only broadcasting wireless g.
Are there any tweeks that can be made or is it just an underpowered chip that cant talk back to the router?
My first post, please be kind.
Anyone else use a 5Ghz wifi network and notice slow performance with the Dinc4G? I have a dual band router, with one network on 2.4Ghz, 20Mhz of bandwidth, lots of interference since I live in an apartment complex of mostly younger people. Everyone has a 2.4Ghz network, most of them are bandwidth hogs and are using 2 bonded channels, so the 2.4 Ghz performance isn't great around here. The Dinc4G gets a solid 65mbps connection on the 2.4Ghz side anywhere in the apartment.
My 5Ghz network is 2 bonded channels, 40mhz, the only detectable network on 5Ghz high anywhere in the complex. My PCs average between 240-300 mpbs on this network anywhere in the building. The Dinc4G barely breaks 20mpbs connection and has latency issues, constant wifi drops, etc.
I'm running a Netgear WNDR3400 dual band router with DD-WRT.
Isolated hardware issue or is this a known problem with these phones?
I haven't noticed any issues with mine but then I haven't put actual numbers to it. I haven't had drop outs or anything like that though.
I can say that I've been experiencing similar issues with a Linksys WRT 610N v1 device, which is configured similar to yours. I'm also utilizing the 5Ghz band for the same reasons. While I haven't measured speed, my Dinc4 is constantly dropping connectivity, despite excellent signal strength. Moving to the 2.4Ghz channels seemed to make it worse.

I have the Netgear WNDR3700. I tried using 5ghz and the speed was the same but with much less range. I use WiFi analyzer on my phone to compare signals and the 2.4ghz signal is always stronger than the 5ghz. If I'm out in the yard I pick up the 2.4ghz but lose the 5ghz altogether. From what I read this is normal, 5ghz has less range than 2.4ghz?
For what it's worth, I use 5GHz for the same reasons with a Netgear N600. I'm usually seeing connection speeds between 52 and 72Mbps and no connection drops. This is being used in my condo & on the balcony. Maybe 1800 sq ft. My tablet, which runs on the 2.4 has frequent connection drops.

Canpitt27 - Yes, 2.4 will typically yield better range due to the signal propagation of 2.4Ghz vs 5Ghz. A radio signal transmitted at the same power from the same gain antenna at 2.4Ghz will typically propagate farther and penetrate structures better than an equivalent 5Ghz signal. 5Ghz is beneficial for users like me in an area with congested 2.4Ghz bands as a means of eliminating interference from nearby wifi networks running on the same frequencies. Multiple access points utilizing the same channel interfere with one another and can lead to packet loss, poor signal to noise ratios, etc. 2.4Ghz is also occupied by bluetooth, cordless phones, and can suffer interference from poorly shielded microwave ovens.
5Ghz is a newer standard in the US, so there aren't as many users on it (yet lol). Of course all of this is dependent upon the quality of the radio equipment in question. I should be seeing results similar to Jafmf95's, where the 5Ghz signal is of a higher quality than the 2.4Ghz signal, but that isn't the case sadly . Neither band is particularly impressive on the Dinc4G, though I do experience more drops on 5Ghz than I do on 2.4Ghz, which makes no logical sense as the 5Ghz signal is of a much higher quality throughout my building than the 2.4Ghz.

I have very frequent drops on 5ghz. And none on 2.4. From what you explained that makes sense. I definitely have leas range with 5ghz. I lose it if I go upstairs in my house.
Thank you for the very good explanation. I understand much better now.
Glad I could help! I'm usually the one on the receiving end of help on XDA as I'm far from an Android / Linux guru heh.
Whe you're connected to a 2.4GHz hotspot, what's the speed you get into the settings menu? Do you only get 72mbps or 150mbps (in the case you take advance of a 40Mhz band).
I'm asking since, on the same 2.4ghz network, my g5 only "sees" 72mbps (apparently it can't use 40mhz band) while other devices, e.g my laptop, connects with a 150mps speed.
Bonus question: have you ever experienced interference between on board bluetooth and wifi?
In my case the speed I get with bluetooth on are significantly lower than those I get when bluetooth is off.
I think I only see 72 Mbps as link speed, even though a have a powerful router at home, capable of 300 Mbps on wifi N with 40 MHz channels.
Will test further.
I have done a side by side comparison using a Pixel XL 1.
One next to each other, connected to the same wifi network,
the G5 always has half the link speed as the Pixel.
150 to 72, or 100 to 48
So G5 definitely has an issue, and a lower wifi speed, possibly cannot do 40 Mhz wifi channels
6MB/s upload and download(with 15MB/s internet), 5ghz wifi n work with 15MB/s download
i digged among PDF documents about the broadcomm chip: this device cannot use the 40mhz band, only 20mhz
Hi, I can't seem to find an answer to this, but what consumes less battery:
putting my phone in 2.4ghz or 5ghz for the mobile hotspot?
Cheers
