Hard to detect 5 ghz networks?

Maybe its just the fact that it's a phone. But I have a 5 ghz network at home and the galaxy s2 cannot detect the network from 10-15 feet away. I have to move as close as 5 feet before it detects the network. Oddly enough though it can maintain the connection as I move away to my room.
Not a big deal because I have 2 routers with one with 5 and the other 2.4 ghz for the phone, but just saying that I dunno why the range detection for 5 ghz networks is so poor.

I have a dual band router and my phone seems to detect both fine. Although the 2.4ghz is more reliable.

Yeah, I have the same problem. I move away from room, where the router is, and my phone can't detect the 5ghz band. 2.4ghz no problem even outside of my house. I wonder if this is an issue with all Skyrockets.

it might be the nature of 'wireless N' itself, I think N is most efficient the farther away from the router you are provided signal strength is sufficient.
maybe you're getting interference somewhere near your router?

5Ghz bands by nature have a relatively smaller range. I have an E4200 v2 router, which is a high end linksys router and i use the 5ghz for N band because i stream a lot of HD from my computer to apple tv, or do a lot or LAN transfers. My E4200 5ghz is easily available in my entire house, but it always has 1 bar less than my 2.4ghz connection. The fact that 20 feet away you don't get the signal is your router not being very powerful (unless you have 10 walls seperating you from router). I would suggest to put the router in a central point in your house, elevated. I have stairs that go down to the basement in the middle of my house and i stuck velcro and glued it to my ceiling. I have a 2 story house + basement and i can get the signal very well 40ft away
You can also use an app called Wifi analytics to scan for interference and see if you have clogued up channels

Yeah I'm aware that 5 Ghz networks have worse range than the 2.4, but I use the 5 GhZ in on my dlink because of all the 2.4 in my building. inSSIDer shows that I'm the only 5 Ghz around my floors. Less interference is always good. Plus my laptop's network card (intel 6300) has no problems detecting and connecting to it. Same with my HP touchpad.
I guess it's just the nature of the phone itself. Which is why I have 2 routers (basically a dual band).

Wifi Turns Off

My wifi turns off almost instantly after turning on. Sometimes it will connect to my network and other times it's a no go.
This is a wifi only version and I'm still in the return window so thinking about swapping it out or just taking it back
Android Version 3.2
Kernel 2.6.36-P6210UELA3-CL616928
Build HDJ85B.UELA3
I've been googling for a couple of hours
Stock reset device and wifi sleep policy is set to never. I have nothing installed
thoughts?

I assume that other devices connect and stay connected just fine?
There are wifi tool apps (https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer) that might give you a little better insight to what is happening

Yes, all other devices work fine with the router.
I have tried both DHCP and static and have assigned a specific IP to the tablet from the router.
If I could get the wifi to stay on i'd see what I could download
Edit: Seems to be something to do with the router. I have two in my house (one upstairs and one down). Both resolve back to my uverse model so the routers are just wireless bridges I guess. If I connect to the downstairs and turn wireless off and on I have no problems. If I connect to the upstairs router things go down the crapper

by chance is the upstairs router wireless-n?

Yes. the upstairs is wireless N
Think if I changed it to G only it would work better?

Solution : only connect to WiFi G ?
I have the same issue on my european GT P6210, connected to a Netgear WNDR3800, which has dual band WiFi (2.4GHz B/G/N and 5GHz A/N).
Yesterday evening, everything worked like a charm on the 2.4GHz band supporting N (up to 130Mbps) but today the connection is really random. I tried to connect to the 5GHz band network but to no avail.
So I restricted the 2.4GHz band network to B/G only (up to 54Mbps) and it is way more stable.
HTH, too bad for the DLNA streaming

in my experience the wireless N on the tab + is downright unstable. using wireless G tends to correct this problem. and since i can think of no reason i need 130mbps throughput to the tab, i see no reason not to continue using the G. disappointing though. the tab 7 experiences the same issues

Did you set the tab to only use G? or did you set the router to only broadcast G? I had to set my router to only broadcast G

I have had this problem with 3 different Galaxy tabs. Keep in mind that this is connecting to a work WIFI using wpa2 enterprise. Boggles me that it connects for like 2 mins then drops, only way to reconnect is to disable/enable the wifi. At home using wpa2 non enterprise I can connect perfectly with no drops.

Wifi showing 1Mbps connection speed

Hello guys,
I just received my Motorola Photon Q mobile. Asked Cornholio to do the SIM mod.
Tested my new phone yesterday with carbonROM . Well I Must say all looks good except wifi.
Wifi speed is showing me 1Mbps
My old xperia mini pro is showing me someting around 70Mbps. My wife has got new mobile too ( Lenovo Vibe X2 ) and she has 150Mbps.
Even her old Iphone 4S is showing her 70Mbps or so.
So it looks like there is some problem with my new phone.
My router is Netgear JWNR2000V2.
Do you guys have some experience with this ?
Thanks a lot

Is it actually slow?
You won't get 150 or even 70 mbps as the phone doesn't do 802.11n IIRC. G is limited to 54mbps, and that is 'ideal'. Also the phone doesn't do the 5ghz band, so you are limited to 2.4ghz.
Unless you wifi speeds are actually slow, who cares what it says it is connected at.

That's not completely right.
It does 802.11n but not the 5GHz band.
It also has only one WLAN antenna, so the speed is limited.
Looking in OpenWRT it shows for my PQ:
RX Rate -> 72.2 Mbit/s, MCS 7, 20MHz
TX Rate -> 65.0 Mbit/s, MCS 7, 20MHz
MCS Index -> http://mcsindex.com/
Btw. it is actually better using 802.11n over 802.11g.
So don't disable 802.11n in your router, consider to disable 802.11b instead.

Well yeah it is slow.
I was not able to connect or load the Google store yesterday on my new Photon Q.
But I must say it is connected. I saw some threads whre ppl were complaining that wifi is connected and disconnected after some time. I do not have this. I have just this connection speed is 1Mbps So watching youtube videos or surfing web on the phone through wifi is not possible at the moment
So I am oging to do some testing today. Hope I will find the problem.

I was never able to get my N network to connect... but I may have been forcing it to 5ghz, which explains why it wouldn't have connected.
I haven't used my Q in a year or so personally, so this was all from memory. Either way, the hardware is 3 years old at this point, so the newest wifi tech is a bit beyond its manufacture date.

@arrrghhh, sadly I cannot disable 802.11g in OpenWRT with my router (a driver limitation I guess) so I cannot test it.
There were also some limitations on wether it connects and if it is stable (a wireless setting "preamble" [short/long] caused me random crashes).
@Jovzin, if I remember right, there have been reports that a defective WiFi antenna might be the problem.
Though, I'm not sure where and how the antenna is connected. I only know that there is a "special plastic" within the phone, which replaces the antenna.

Do you think this will help ?

Cause I am desperate. I tried now to do the Wifi tether from my wife's new mobile Lenovo vibe X2 the phones were close to each other and still 1Mbps Crap
Did test with my router: When I was about 5 meters away I got 26Mbps. I got closer to router and it drops back to 1-2 Mbps. So really do not know what is happening crap.

What is your router configured to broadcast? Have you tried changing any of the settings? Are you sure the hardware is OK - did you test it before the SIM modification?

@Jovzin, it might help, yes. (Shipping costs are pretty high.)
But first you should open your PQ and take a look.
Maybe CornholioGSM just forgot to attach it correctly and you don't need to replace anything.
Also, please answer to arrrghhhs question.

Are you sure it isn't a power saving function? Try downloading something in the background and then checking the connection speed.
My droid 4 also connects at 1Mbps when the connection is idle. Laptop wireless adapters also commonly do this to save power - they show their unthrottled speed on the wireless panel but you can see it connecting at 1mbps when idle on both the router and 3rd party wireless utils.

Hello some good news.
I did a factory reset.
And now somehow it is working. And I am sure taht I have uncheckd that battery saver for wifi.
But when the phone is idle it is 1Mbps. When I am downloading somethign from store it is 65Mbps. Hmm there is some build in saver ? Which is different than this power saver wifi which I can tick in wifi options ?
Anyway I am happy that somehow it is working
Thanks for help guys
If I may one more question.
It is possible to watch HD youtube videos on PQ ? Cause in youtube app I see only 360p Was hoping that there will be option for 720 at least...

If you enabled 40mhz channel width on the router (you're using 20mhz now), you could double the 65mbps to 130mbps, but this only really works well if you're using 5ghz channel, or have a very quiet 2.4ghz channel, otherwise you're subjected to more interference.

Correct.
In 2.4GHz (what the PQ can) it is contraproductive to use 40MHz channel.
It even can be slowed down in a "noisy" environment (I gave it already up).
Also, this is ruthless to your neighbours, so don't.
In 5GHz it is only usable if you can use more than just a few channels.
Even then, it is obvious that most devices are 2.4 GHz and just "a few" can 5GHz (the PQ cannot).
So it actually is not a problem to use 40MHz channel in 5GHz. In future this might change.

5GHz WiFi Issues

Hello! I'm wondering how many others out there may be having issues with the 5GHz WiFi band on their Galaxy S6? My wife and I are both running a Telus 64GB model and haven't been able to connect to our 802.11ac band since we got the phones last week. I've tried every available channel on 5GHz mode and even turning down the number of channels bonded and enabling 802.11n/a only, but the issue still persists.
If I turn off the smart switch feature, I can at least stay connected and it says I've got a strong signal (anywhere from 580 - 780 mbps) however nothing loads online. I'll also notice that if I am connected to my Chromecast, the signal almost always dies as well so i doubt it's internet-related (although I have tried switching up the DNS entries on my router)
The router is an Actiontec R3000 with WPA2 security, but I noticed I was having the same issue last week on my friend's RT-AC68U when connected to the 5GHz radio. I've never had any issues with my iPad/Apple TV/laptops when connecting to the 5GHz channel on this router.
Any kind of feedback either way (same issues, resolutions, etc) on the concern would be greatly appreciated!

Terrible wifi downlink speed over 5GHz

I'm having some serious issues with my 5GHz connection on my brand new Honor 8. 2.4GHz works just fine, getting around 40Mbps which is expected for 2.4, but sometimes on 5GHz I'm not even getting 1Mbps down... However, the upload speed is mostly fine.
I have a 100/10 connection btw. Asus rt n56u router with padavan firmware. Not experiencing this issue with any other devices. I have tried changing channels on the router, and the bandwith to 20/40 only but it didn't make any difference.
What might be wrong? I appreciate any help I can get.
Thanks.

Have you tried rebooting the modem/router? Sometimes that helps.
Ps i`am getting 200-240 MB download speed on my 300 mb 5Ghz router.

Yes, multiple times, unfortunately it didn't make any difference.
However I noticed something interesting now, it only seems to suck in my room. When I went to the kitchen I was getting around 90Mbps. Can it simply be interference? But what else can there be in my specific room that operates at the same frequency? And why is only the downlink bad, and why isn't it happening to any other devices? It seems weird to me...

Use wifi analyser to check issues. Sometimes when router is set to auto channel, it may setup the connection in such a way of excellent short distance data burst but medium/long distance signal loss. Check for channel overlap.
Also 5Ghz is by nature a closer range frequency, compared to 2.4Ghz.
First you must rule out phone problem: test with other network and/or router at 5Ghz. Even using different wifi equipments doesn't mean a thing. Same chipset can have different implementations and network antenna.

Its just the range of the 5GHz signal. The maximum usable range of 5 GHz Wi-Fi is 3m and 2.4 GHz Wi-Fi is 12m. Thats all its nothing to do with your device. Walls etc will reduce that even further.

Max 5ghz speed only 433Mbps
Anyone know a way to get more? My router is capable of much higher speeds. On my Nexus 6P I got around 800+

1. install WiFi analyzer app and see what channels are being used most by 5GHz networks. If is set to automatic, manually set your 5 ghz network to an unused channel (try using the lower 5GHz channels instead of the upper ones)
2. there's an existing bug in Android where connecting to some IPv6 routers makes data lag. Try turning off IPv6 or at least IPv6 broadcasting on your router.
3. make sure your router firmware is up to date.

Unfortunately after further research last night I'm afraid this is simply a limitation of the of the wifi chip on the phone itself. I use wifi analyzer often and always keep my firmware up to date. I've tried adjusting various settings, even using other Wireless AC routers. 433 is the highest the phone will go. Perhaps Huawei can push an update to remedy the situation.
