wifi - Galaxy S II Q&A, Help & Troubleshooting

hey people,
i able able to connect to my home wifi no issues. yet when i am at work it says connected but i can not access anything on the internet. one thing i have noticed i do not have cell reception at work. is always been that way thats why i use wifi. i have tried restarting wifi and reconnecting. also the bars are grey not blue like usual.
i am on cm9.
thks

Two situations i can come up with:
- The company uses a proxy connection to connect to the internet.
- Your WiFi MAC address has to be registered to properly connect.
If possible, you should contact the company's it helpdesk to help you further.

HD2 WiFi Internet Problem please HELP

In the Wireless Networks it says "Connected" next to my "SSID" i have the correct key and dns/static ip setup. I go on Marketplace, internet browser (Opera), and another internet browser (Skyfire) and none of them work, so basically I'm connected to my router but I have no Internet.
I have HSPL3, ChuckyROM, and Radio Radio_2_11_50_26, I used to have Radio 2_12_50_02_2 but the internet didn't work with that one either.
What could be wrong??

First off why are you using static?
Second have seen these types of issues before with static , try dynamic(DHCP).
well i have to use the dns, i don't need the static ip, i switched to dhcp and only input the dns but it is still not working.

In your settings, when you configured your wifi , in the box that says "connects to:" did you select "The Internet" or "My Work", this should be Internet ...
yea its says "The Internet" and by the way, after i removed the static IP my connection just says Unavailable when i try to connect (I hide my router's SSID so i input the stuff manually)
Oh and i had a motorola cliq before and it connected just fine
ok so for some reason i retried it just now and the internet works...so i guess problem is solved
Hi, I searched the forums and found this thread regarding wifi Internet problem so I'm posting my problems here.
I'm having similar wifi issue. I can connect to home router just fine but when I'm out using either free wifi from some stores (like panera or starbucks) or School wifi, it shows up as "Connected" but when I try browser it won't even show the home page or log in page. I switched from "Work" to "Internet" but it still won't work...
I don't think it's hardware problem but more so OS problem or something i'm missing. This problem only occurs with WinMo 6.5(I use stock rom), and when I boot Dan Android, wifi works fine. I'm not sure if Android's usage of wifi is somehow affecting my WinMo's ability to log into wifi but this is my wild guess.
If someone knows what my problem is could you please help me?
thanks
i think my problem was that when i tried to connect to my wifi, my hd2 was connected to my pc via usb. when i tried to connect when i'm not connected to my pc it worked
that's about all i know, hope it helps
did recognize this too...i think w-lan is disabled when active sync is activated...because the phone can use the internet connection of the pc.
back to topic: do you use static ip's in your home network or does the other networks (school) require a static but you're on dynamic ip?
DN41
hm, I have no idea which ip I use when I'm connected to home or public. How do I check?

wifi good..no data

Vegan gb 7.0. I can connect to the web just fine, but I can't download anything and anything needed for a data connection wont work. It's an intermittent problem, my wifi status bar will be white when it doesn't work and green when it does. Pershoots latest kernel.
I've noticed the same thing with the white icon vs. green icon when using wifi that is filtered/proxied. Like using wifi at a local coffee shop where you have to agree to the terms of use. You are connected to the access point but not to the outside WAN.
I think your connection issue may be more network related than device related.
What type of wifi connection are you using? Is this a personal one or a public one? Do you have access to the router's configuration? (Linksys web interface is 192.168.1.1 by default, for example.)
Personal wifi...psa2. I put my tab to sleep last night not working ...now it is. I've restarted before and it didn't fix it. Belkin router.
Yes this is happeningto me.....so when thewifi is green I can download but when its not I cannot download..... I did nothing itjust goes back and forth from time to time ....anyone know how to fix???
Network troubleshooting.
To the best of my understanding, this occurs when you have connectivity to the wireless access point, not to the internet itself. I think it turns green when it is able to contact Google services. Generally, this would mean that your wireless router is either not reaching your internet service provider (ISP), or there is a proxy not allowing your device to use the access point as a gateway to the ISP.
If you're on a public network, like Starbucks, McDonalds, etc., you may need to agree to an acceptable use agreement. I've found I need to use the default browser for this.
If you're on your home network, the next time the icon is white, check the following things.
Are any other devices on your network having a similar problem?
Does your modem have power? and are the lights indicating trafic?
Can you access your modem's web interface, and run any diagnostic tests to be sure it's reaching your ISP? (You may need to contact your ISP for further instructions.)
Is your router able to contact the modem?
To determine if this is the case you'll need to trouble shoot your router and its connection to your modem.
(The following are some defaults.)
Model IP address user password
Linksys 192.168.1.1 admin admin
Belkin 192.168.1.254 admin "blank"
Netgear 192.168.61.1 administrator password
I could have mixed up one or more of these, but it's one variation or the other.
The info may even be on the bottom of your router.
Once you've accessed your router, make sure it's getting an external IP address from your modem.
Let me know if any of this helps. I'll try to get back on later this evening. Leaving work now.

Galaxy S2 is able to connect to wi-fi router but can't access Internet ??

hi,
I've linksys wi-fi router model WRT54GH in my home & it has a good amount of signal strength to cover entire area.
My recently bought galaxy S2 is able to identify linksys wi-fi access point & connects too with the IP assigned to it, also at wi-fi settings connected being displayed.
Now when I try to access Internet (any url google/FB), it doesn't connect at all.
I tried almost everything about router configuration, restart etc. but with no success
can someone plz help on this ?

In my case the problem was with frozen "WiFi sharing" in combination with juicy defenders "Location" fearure. It seems such combination is dangerous. Solutin (in my case):
1. defroze
2. remove all wifi networks
3. reboot (for "clean" frozing)
4. make WiFi sharing frozen
5. reboot again just for fun
Try to check your router's MAC address restrictions. In my router, as security, I have to add MAC addresses of each device to share internet. They take IP's, connects etc. but does not have accesses to internet
as above, check that there is no MAC filtering set up.
one other thing it may be is the security settings, if you have a WEP Key to access the router it may need the Hex conversion of your key depending on what level of security you have (64bit or 128bit for example)

Try setting up a static IP address for your phone, I presume your network is a 192.168.1.0, go into router settings and LAN setup, give your phone the address in a static DHCP assignment of 192.168.1.5, or any other address in the same subnet your in. Some SGSII's have problems with dynamic DHCP for some reason, some NS had the same problem too,

I have a similar problem and I fix mine temporarily by turning my wifi off, then in wifi settings > advanced, I change wifi sleep policy from 'never' to 'only when the screen is off'. However I have to do this every time I want to use wifi so it can become quite annoying sometimes.
So I can get through however only for a short period of time as it seems as long my Galaxy S2 keeps turning off my wifi even though it's on :/
I had exactly the same issue on Linksys E4200 with my laptop, could connect to network, even to router's attached storage, but not to internet. Restart helped
On SGS2, I couldn't connect to the router at all at first, but fixed this by switching from WPA2/WPA mixed mode access protocol to WPA2 private. But I guess this is not exactly your issue.

Yes, you are right this is not an issue for me.
In fact my SG2 being assigned with an IP address from 192.168.1.xx subnet.
Also at a same time my laptop connected with an IP from same subnet able to ping SG2.

My SG2 being assigned with an IP address from 192.168.1.xx subnet.
So I think IP addressing may not be an issue.
Also another thing I tried was, at a same time my laptop connected with an IP from same subnet able to ping SG2.
So wi-fi router may not be an issue here, whats say ???
Even I am facing the same issue at my office network. I am able to connect to the wireless network but if I try to access any app I cannot browse. This is really frustrating looks like some issue with the modem drivers.
I was able to browse on another wifi created virtually by mobile tethering. This looks like a major bug with the current firmware. Another interesting thing to note is that the Wifi network has a hidden SSID and uses WPA2 auth scheme.
I have seen a Galaxy S able to connect to the same n/w without any issues.
Has anyone figured out a solution to this one ?
Hi, thanks for your reply.
I am yet to figure out a solution for this
Even I am also agree on the probable issue with modem driver.
I've D-link modem.
Are you aware of anything about this modem that can be reconfigured to get this worked ... ?? pl let me know
The wifi router at my office is Cisco Aironet 1200 Series, anyone else facing this issue ?
I'm having the same problem at work connecting my SGS2 with v2.3.3 Official Firmware (customized for Orange service provider) to a Cisco Aironet 1130 AP. I can see that the Galaxy authenticates with the AP correctly and gets IP from the DHCP server, but it cannot send or receive any traffic, although the phone stays connected and authenticated. At home, I use an Atheros based Fonera with DD-WRT without any problem.
As I'm the company's network administrator, I will try to further investigate this problem, but it seems like some kind of incompatibility between the devices or misconfiguration ....

try turn off the wifi, turn off the mobile data and turn on the wifi again
It seems the SGS2 sometimes has problems with DNS.
Try a static IP and use 8.8.8.8 as second DNS server, which is a free Google DNS server.
This fixed MY problems
I rooted my SGS2 and voila wifi worked at my office finally I have been able to find a solution.. love my SGS2 the Beast...
I'm having this same problem..
I think I've tried all the solutions above, but one (Sorry - noob question):
Rooted?
is there a firmware patch or something that I should know about?
Anyone got any other ideas?
ETA:
I can connect to hotspots (DHCP) and at home (Have to set it to static tho)
No internet
AP works - Laptop and i8910 (had to set static and advanced settigs etc). I've rebooted it a few times, set DHCP on and off. DHCP seems to be running on the router

This is an issue with SGS2 with wifi server using authentication protocol TPIK, if you use AES as encryption then it will work without any issues.
That should be a setting in my AP? I can't see it...
If I get a new non-crappy AP is that likely to solve my problem?
ETA:
Ah - that's a WPA thing? Mine only seems to do WEP - is that right?

VPN direct connection - problem

Hello everyone,
I have problem with VPN software in Android. I wrote "Android" because the same problem appear on every phone with android which I've tried. I have server with which I connect via VPN, server has two internet connections. One is ethernet connection via router (local internet provider), second one is mobile internet. Both solutions use static IP.
Android does not has any problem with connection via router, however in case of mobile internet there is no connection. The program show "Connecting..." and after few seconds there is information "failure".
Settings of those connection are very similar. Anyone know how to solve it ? I know that my description is probably a little bit chaotic but I'm willing to explain everything because it is quite important.

Problems using a wifi login network

Hi!
I'm on an Asus ZE550KL. Now, i use to connect to a wifi network offered from my city. Fact is, it needs a login to use it. With some devices the login is "bypassed", so i connect to it and i'm ready to surf.
With my old phone if i remember right it was baypassed. Now, these days the network has problems, so on pc i can surf, but there is a sort of problem with login so after i insert credentials, there is an error, can't reach the server, so on phone i'm out of wifi.
Now my question is, why this difference on devices? Can i maybe change something about it? I'm not rooted.
Thanks!
