Wireless-N - Galaxy S II Q&A, Help & Troubleshooting

just got my new s2... loving it. one quick question.... have a wireless-N router thats in wifi-N mode only... yet my cellphone barely gets a good signal off it when i hit 10m away... plus i only connect at 54mbps "wifi-G". is there a way to enable wifi N or its auto ?

You could try forcing in Wi-Fi Settings - Advanced - Regulatory Domain - 14 channels.
Not sure it'll help.

Hero's Wifi problems

Hi,
so kernel sources are released. Is there any fix for hero's wifi problems? I mean dropping connection to AP. It is so annoying, I tried to do everything: change channel, mode, encryption... Nothing helped. It is Linksys wrt160nl. The same applies to other networks (some public hot spots).
I never had this problem with my Linksys WRT54GL...

Could you paste your wifi settings? (mode, encryption mode, channel)
Using the Modaco custom ROM 2.8 (never had problems with modaco ROM and generic)
Router: Linksys WRT54GL running Tomato 1.25 firmware
Wireless Mode: Access Point
B/G Mode: Mixed
Channel: 1 - 2.412 Ghz (try a free one)
Security: WPA / WPA2 Personal
Encryption: AES
Group Key Renewal: 3600 seconds
No Mac Filter
Under Advanced Settings I changed "Transmit Power" to 251mW for a better signal, the rest are default values.
Try to update your router firmware
Are you alone with this problem?

In case you haven't done so yet. Check out the Wifi Sleep Policy (access by pressing menu when you are in wifi menu). Normally the Wifi is turned off then the screen is turned off which can cause problem.
Similar problem with netgear wnr2000

Hi got similar problem with my router netgear wnr2000.what i found funny is that when i reset the router, the phone connects perfectly to the router, but after abt 24hrs or so, it fails to connect.even if i reboot my phone, or reset the connection on phone.fails to connect.it will only connect when i reboot the router. i will try the 'aes' encryption n see if that helps.will update if it works
Thanks for your replies. Please could other members share their experiences, used options and solutions. This issue is too common to simply forget it. I am trying to find some kind of pattern or special options, it requires.
i dont have a problem with wifi apart from the wont find or connect to n-range device other wise i use wifi all the time it never drops, on stock orange uk firmware
I have a Sitecom WL-173 router.
I cannot connect at all. I can, but only with no or WEP security. That is no option for me.
When I use WPA or WPA2 my Hero does view my network, but does not connect.
I called HTC about this problem. He told me that they do not support all routers. He could not tell me which they support and which not.

I also have the same problem. The way to solve it is to change the above setting to 'G' only. Not mixed/Hybrid.
Cheers!
I have not had any problems trying to connect to WiFi networks, until i went over to my mates place where he has the Virgin 50MB B-Band and also a D-Link wifi-N router, and my Hero could no see the network at all, even though his iPhone connected straight away.

I'm sorry, it hurt even more when i was sitting there pissed off that my Hero wouldnt connect to the Wifi!!!
I have Virgin 50meg at home no problem at all, went to my GF's who has basic Virgin cable 10meg on netgear G and would not connect at all.
No idea why, as it should be all fine!
I have the same problem. It is so ****in annoying. My router is a Linksys WRT54G with Tomato firmware v1.25. Router is in "G only mode", WPA-2 PSK-AES security, I've set a static local IP for the phone, the phone's wireless is set to always ON... I basically tried everything I could think of. Ended up rooting the phone and installing Modaco 2.9... but didn't change anything. The only way I can get it work again when it drops is shut the Wi-Fi off then on...
Worst of all this is the problem seems widespread (but not universal)... What the **** does HTC think putting a ****in smartphone on the market with defective Wi-Fi... This is non-sense.
I really hope someone comes up with a fix or HTC updates this... otherwise we might want to start thinkin bout class action.

Is it a router setup or a Hero setting?
Pleaes explain if it's one of the options
probs here too ...
Linksys WAP54G v3.1
vs
HTC Hero
was working perfectly for first month or so, but has been getting worse and worse. ie, for a few weeks it would see the wifi but would usually fail to connect. now I'm lucky if it can see it at all!
have reflashed the wap with dd-wrt and experimented with a lot of settings. no diff.
have reflashed the hero with hero21 comunitry v1.6. no diff. (and also latest radio)
it just starts and stops when it feels like it.
oh, and my eeepc works fine on the same wifi, so I know it's not some wap screw up.
tried every tip I can find like 'use mixed mode' or 'g only', etc etc.
I am starting to think it's a hardware fault?
Same problem
Siemens Gigaset Tiscali modem with wpa psk2 tkip and T-mobile hero rom.
Sees the modem and connects with security first time but then says 'remembered out of range' on wifi settings but interestingly in wifi buddy it constantly has the syncing symbol next to the network.
Really annoying.
I've tried WEP and security off, wireless g only etc etc.
I have problems too but seems different to yours... but who knows : in fact i can't connect to wifi when the SSID is masked. Even if - or course - i put manuualy the ssid before with the good wep key. It happens on a livebox ( orange box )... but if i press the button to show the wifi network - it has to be made when you connect a device for the first time on this box - then it connects to the network... else it tells me that the network is out of range...
So does the wifi on hero has problem with masked SSID ? To compare i never had this problem - on the same box - with the touch diamond and the touch hd... and at home, not masking the ssid, the connection is ok without doing anything.
Ciao
Fred
I had the same problem with a Zyxel 660 router. I was able to connect to the wifi (WPA/PSK enable) but there was no data transfer possible.
So I updated the Radio ROM to the 63.18.55.06JU_6.35.08.29 version and it solved the problem.

[Q] Wireless N on SGS2?

Hi guys, anyone can help me out here with regards to connecting our SGS2 to Wireless N network? I have tried changing my radio frequency setting and even resorted to using WEP authentication instead of WPA, but I just can't get the phone to connect via N network, it always connects via G instead. But under the same settings, I am able to connect my acer laptop and my wife's iphone4 to the N network.
Is there any specific settings I need to configure on my router? I am using a Prolink H5004N adsl2+ modem with wireless N router. The modem is compliant to IEEE 802.11n standards, not draft-n and should work with the SGS2?

Not sure, but I think that it will connect if your N-network are in the 2.4 GHz frequency area, but not in the 5.0 GHz

Yup, tried that too, but still connects to G only. I have also tried configuring router to accept only N networks instead of G/N, but then the SGS2 will not even see the SSID when its performing a wireless scan.

Ive got the same issue. Router Asus RT-N16 (b/g/n, 2.4GHz). Playing with different router firmwares, settings and so on - no luck so far.
Check the "advanced" settings by pressing the menu button in the wireless and make sure nothing wierd is set in there.
Otherwise, as long as the router is set to N only on the 2.4ghz band, it should at _least_ see the SSID.
That modem supports WPS, try pressing the WPS button on the back of the modem and then use the "WPS button connection" option in the wi-fi settings menu on the SGS2.
Remember the single-channel 802.11n 2.4ghz such as the SGS2 supports will only max out at 72mbps anyway so there's not a huge improvement over the 54mbps that 11g will give you, although 11n is more efficient.

I've got the same unit and it works fine with it, that said I'm running a recent build of the Tomato firmware on mine. I don't think I even powered it up fully with the original firmware...

thx for fast reply
SGS2 can see SSID, but fails to connect until I force RT-N16 (with custom firmware, RT-N16-1.9.2.7-rtn-r3121) down to "Use 802.11 G only".
Never had any problems with other 802.11 N powered devices.
only wpa2-aes or no encryption are N-standard

wireless N only officially supports either WPA2-AES encryption or no encryption. Devices with drivers that more closely comply to the spec will not connect to WEP or WPA.
I hope you fixed the issue. I stumbled across this thread while asking the same question; maybe someone else will benefit by having this thread wrapped-up also. No haters, egos, persons, etc please. It's been necessary already to block a few of you.

WIFi signal never more than 1 bar

Wifi signal on this phone is never more than 1 bar and i could be in same room as router which has a/b/g/n and the signal always cuts out completely
is there any fixes for this ?
Did you try changing the router's settings? Enable only 1 band at a time. Also I would try changing the routers security protocol. Some routers also have a setting for adjusting the transmit power to use. At 10% I had one bar at 12 feet. my htc sensation wouldn't play well with N bandwidth enabled by itself but it was fine with b/g/n.

Thank you for the reply, but I do not always have the right to touch the router - in a cafe for example and even in a office...
any other solutions to the wi-fi problem?

Thankyou greeky510
Now I have full bars
What I did was change router to exclusively G ,I tried N first but only got 1 bar
And signal to frequency 11 from 1
while this fix does work where you can access router this problem will remain for routers outside of the home
my galaxy S 2 doesnt have this problem at all it always gives a good strong signal no matter where as long as wifi is in good range
You are very welcome maniAK. Unfortunately my technical skillset has reached its limit with a phone i have no experience with since i'm still waiting for my Razr Maxx in a few days.
I'm only guessing that the problem is that the rest of the routers you mentioned use either a dandwidth that your phone doesnt play well with or an authentication protocol that it doesnt like. Try turning off LTE, GPS and BlueTooth and see what happens then. Also try holding the phone a "different" way.
I would still go to Verizon and request a replacement phone, just to make sure there is no hardware issue with the phone.

[Q] S3 Wifi, Roaming and Time Issue. Please help

I am away form home now and facing some frustrating issues with my new S3.
1. I cant connect to any WIFI network though the WIFI connection has very good signal strength. I always get the msg 'Network disabled. Poor Connection'. There is nothing wrong with the WIFI as i can connect it with my laptop and my buddy could connect to it using his IPhone.
2. My roaming time is completely wrong. It does not follow the time of the country I am in. It is showing the same time as my home country network. Shouldnt it automatically detect the network and shows the correct time like Iphone?

1. Restart the router & try just using 2.4Ghz in settings > wifi > advanced
2. Ensure: menu > settings > date & time > check [auto date & time] and [auto time zone]

1. I cant restart the router as i am connecting to the Hotel's wifi. Everything else can be connected to it except for this S3. I followed your instructions but it keps showing "Connecting". and nothing else happens.
2.I have already check both auto date & time and auto time zone earlier. But the problem still persists.
Please help
Beginnin to regret my decision to get a S3. So complicating!
If you happen to have a case on, remove it and try again.

Hi, this is my first post, as I created my account specially with the purpose to answer you.
After being faced with the problem all day and reading all possible materials on the topic in google and here, my dad walked in and asked me why he is not able to connect to our home wireless connection.
This was when I retrieved my hope that the problem is not in the phone. And it was not! My iPhone, my laptop were able to obtain a internet connection in contrast to my other laptop and my S3! I restarted the rooter and everything was ok! Everbody got their internet dose !
So, most probably it isn't you!
Also have wifi problem, except it tells me it's an authentication error. I cannot connect to the WiFi unless I stand right next to it. Can't connect to WiFi anywhere (if you think it's the router in my house), even though the device detects the router. Sent it back to Samsung.

Hey, I experienced the same problem. But in my case, I am able to connect to the AP, if I am using a static IP address in the SGS3 instead of DHCP. Same router, no settings changed there. Just configured a static IP.
Cheers,
Jaegermeister
Same problem
Tried everything still not working, took it back to samsung they said it's working fine any other device is connecting without a problem but the S3 wont (i have 15 S3 with this problem)
Thanks
Bring back the phones to Samsung!

I'm also frequently getting the "Network disabled. Poor Connection" message when at home. I have 2 wifi routers:
- Buffalo WHR G54S
- Draytek 2920n
If I turn wifi off/on on the S3 it sometimes resolves the issue, but not always. Sometimes after turning off/on it shows a status of "Connected"but there is no internet connectivity. If I then switch to the other router I can sometimes (but not always) connect successfully.
I'm running Checkrom v5.5, and have tried both the Perseus and Siyah kernels - both have this problem.

[Q] Connecting to 5Ghz wifi

Dear All,
the phone sees the 2.4 Ghz wifi but not the 5 Ghz wifi anyway to solve this
regards
A lot of times this is router related. I have to set my channel width to either 40 or 20 in order for it to work. Be sure that you do not have it set to Auto or Mixed on your router.
Dear Globalrebel
Thanks for replying, I have already tried with auto & selecting each channels individually but still my phone doesn't see it, on the other hand I can see the 5Ghz wifi on the Iphone & on the note3
Regards
I'm not sure I have any suggestions for troubleshooting but I can see my 5Ghz WiFi at home and at work on my S6. At work I connected to the 5Ghz rather than the 2.4 and have not had any trouble with it.

Maybe you hided the 5Ghz SSID from broadcasting?
Try creating a new Wi-Fi connection on the S6 manually.

No, My SSID is not hidden and tried to add it manually still no success
any app to confirm if this is faut due to faulty hardware in the S6 edge?
Regards
Any possible way for S6 to see wifi 5Ghz channels 36 40 44 48?
regards
Same problem with S7
I have international version of S7 and I can't connect to 5GHz either.
Do you think that flashing a firmware from a different region can fix this.
Has anyone tried doing this?
