802.11ac on gt-i9500 - Galaxy S 4 Q&A, Help & Troubleshooting

Has anybody seen issues with the 802.11ac network on the s4 gt-i9500. I can get 100% signal throughout my home but I am only able to browse when I am in front of my netgear r7000 router where I get 120mbps connection speed.
I can't browse from the bedroom upstairs although I get 100% signal but only 6mbps connection speed.
My nexus 10 which doesn't have 802.11ac has better connection in the bedroom.
Please let me know if its the problem with the phone and not the router.

Wireless N

Does anyone know why the wireless N channel of my dual band router doesn't show up on my A500?

+1..
Can't even see my N network either.. My wife's Xoom has a setting under advanced/wireless to change your setting, but my Acer doesn't.
It might be because the A500 doesn't recognize 5Ghz N networks, only 2.4Ghz.

If it's a 5Ghz that could be the problem, but maybe it's just the channels (12 or 13) that doesn't play nice and there's a fix posted already.
Well, mine is a 5Ghz N network.. so that may be the problem. Oh well.
a500 is 2.4 only not dual band like the zoom
Another strange thing.. Speed tests with the a500 are half as fast as my dinc using my wifi

I just did a post about the wifi, since IMO, this is the feature the A500 is weak on.
No adhoc
No 5gz
Weak signal that is unstable in weaker wifi areas
The signal seems toggle in weak areas from one bar, two and zero, disconnects and then reconnects. Rinse and repeat.
My gTablet is a good device for wifi comparisons, but makes the A500 seem weak.

A little help about wifi

i am using Netgear N wireless router at 150mbps
but my phone shows link speed of 65mbps
any way to force the device to connect at 802.11N
Are any other devices connected to the router? If there is and there not N speed the router will only work at that speed unless it is dual band.
No only my phone is connected

any one? please
The Galaxy S uses a very restricted form of the 802.11N. In fact, it limits it to the 2.4GHz band and only a single 20MHz spatial stream.
Therefore, even on a router that supports N, 65Mbps is the best you are going to be able to get.
Ok i understand why my wifi is so bad too. Thanks

Whats your network 5ghz wifi speed?

I get around 3-4MB/s using Airdroid, thats pretty slow since my laptop does 12MB/s. The phone is set to 5ghz, not sure if Airdroid is limited to G speeds since thats about how fast it goes, but my internet speedtest.net speed on the same server is half as fast as the laptop too.
If you have Airdroid I think the easiest way to test the speed is download a large file and see how fast its downloading rather than upload a file.
Using Speed test.net I got 26Mbps down, which would be maxing out my internet connection.

home network file transfer speed not internet speed
Using the 5ghz doesn't do anything faster. What it is is just another band to use. If you live in an apartment complex with 100 nearby WiFi signals, they are all most likely on 2.4. Things get congested. Switching to 5 helps out this.

Poor WiFi Range

I'm on my second Nexus 4 and still can't get over how poor the WiFi range is on these phones. Both of my N4s have had the same results. When I'm in an area of my house about 20-25 feet from the router I get 0-1 bars of WiFi, where my laptop and PS3 both get 80-100% connectivity. Every other smartphone I've owned has had better WiFi reception than this. Anyone have suggestions?

Try changing the security settings on your router to use a different protocol. For some reason that made a big difference for me. Generally I've found the WiFi range to be fairly good.

There hasn't been any security on either router I've been using so I know that isn't the problem. Thanks though.

I'm experiencing the same thing: within 20 feet of the router, signal drops dramatically
I'm getting the exact opposite. I've noticed a huge difference with reception versus my Galaxy Nexus.

Even when I'm standing 10 feet away with the router in site I get 2 or 3 bars. Pretty pathetic

I setup a repeater recently but my nexus still gets 1 or 2 bars with WiFi.

Also experiencing a similar problem. I don't think I've ever seen 4 bars on wifi since my 3 weeks of owning the phone. Almost all the time it's at 2 bars, even when other devices right next to me will have full signal.

Its terrible dude. I've got an iPhone 4s next to my N4 and the N4 is going between 0 and 1 bar of WiFi and the iPhone is getting between full and 1 less than full. Speed tests on the iPhone are also much faster

Are you on 2.4Ghz or 5Ghz band? My N4 refuses to work on the 2.4Ghz band. When it did connect, I would get less than 1MB connection link. Switched over to 5Ghz band, and I get a consistent 72MB connection. It even picks it up out to the middle of the street. Try changing bands if you have a capable router. Hopefully the next update will solve the WiFi problems this phone has.

The router I'm using right now is 2.4 only. When I go back to my apartment next week I can test the 5GHz signal

You guys should give wifi analyzer a try. I it might show that there are other signals on the same band?
I personally get poor wifi signal, but with wifi analyzer I saw that there are a total of 13 networks nearby

Try flashing a aftermarket kernel such as Franco Kernel. You can change the WiFi algorithm as well to see if it improves at all (changable with his app, Franco Kernel updater)
A lot of people reported that R19 and newer fixed their N4's wifi problems.

I get decent range on both 2.4 and 5 GHz ranges. Dont have it set on channels and allow the router to set that. Obviously do to the higher freq I get less range on the 5 GHz range but use this for my phone and my wife's S3 as it will run on it as well. Keeping the 2.4 side as clutter free as possible. Love my dlink dual band router.

The bars really are not a good method of determining anything. My WiFi works just as good as any of my other devices, iPod,iPhone,nexus 7, touchpad and more. I am not looking at the bars though but rather just going by how it works and it works fine for me. I can go as far as my mail box at the end of my driveway..

Hi, I have a Linksys EA 6500 router that has an Wireless ac mode in the 5GHz range. I cannot get it to connect to my HTC One. I have no idea why!!!

You can connect at 2.4 GHz and 5 GHz. this provides wireless internet connectivity using WiFi instead of Mobile internet. This lowers your cellular bill at the end of the month and provides much faster internet speeds for your phone whilst connected to WiFi.
In my case i am able to successfully connect to the 2.4 GHz frequency, but my HTC One does not see the router when i configure the router to 5 GHz frequency only. My Dell Laptop connects, but the HTC does not see the SSID.
Others have successfully connected at 5 GHz and using ac to improve their connection speed, but i have been unable to get this with the EA6500 router ((
I am using WPA-2 for security and i tried both N and ac modes on the 5 GHz frequency. I have no problems at 2.4 GHz and N with WPA-2.
So yo be ssfe I should buy a 2.4 Ghz router?What's s decent name brand, model of a router should buy to connect to my Gs4.hey if you can could you pm me a web link for s good router. Thanks

Unfortunately you need to have an internet connection to your home, connect this to the wireless router (i would suggest ASUS RT-AC66U and not the crappy EA 6500 i bought). Once connected there you should have WiFi distrubuted to your home, and you can connect your mobile phone to this. You can use this to share files etc throughout your home network..
I hope this helps.
