I can't seem to connect to wifi. The phone keeps cycling between connecting, Obtaining IP address and Disconnected.
Anyone else having this problem? Any advice?
Are you connecting to a WPA enabled router? I've had issues on my Droid with certain routers (D-Link for one)... If I switch the router to WEP, it will connect fine.
For a phone to not support WPA is pretty lame. I picked up the TB today but I am at work. Hopefully it will connect to my home wifi network, I will update you on my results!
Had a similar problem on one of my TBolts...power cycle resolved it.
I can log onto my WPA network with no issues. Maybe bad password?
Well, I do use WEP and it will not connect. I turned off WEP just to see and it connects fine when I leave the network open.

Mine seems to be working fine, just connected to home network - I don't get a wireless icon up in the notification bar, but it goes green on my toggle.
So it seems that there is no way to connect to a non broadcasting wifi network in any of the current froyo roms. Anyone got any ideas on how to resolve this?
I have tried hidden wifi enabler and even added it separately, but it just says out of range when its sitting right next to the wireless router. With broadcasting on it connects with no problems.

I've done it in Vegan... what encryption are you using? I know there are issues with WEP...
using wpa2 I heard rumors that tkip doesnt work with it. This correct?
I got mine to connect running stock and TNT 4.4 but it wasn't easy. I intially went into wifi setting and "add a network" typed in the SSID (not being broadcast) and password (WPA2/TKIP) and it would find the network but not connect. I did some searches and found various suggestion but none worked.
After a lot of failed attempts I got frustrated and turned off wifi on the tablet and then turned it back and suddenly it connected with no problems. It may have been a one off thing but couldn't hurt to try it.

Ill give this a try and see what happens. But I am not getting my hopes up.
Just out of curiosity.....
What's the point of connecting to non-broadcasting router?
It's like turning on WiFi in the middle of desert?
JMO.....
turn on ssid bdcst. connect then turn bdcst off.

If your wireless router doesn't broadcast it's SSID, others can not attempt to access it.
My Stock 3588 connects fine
I have a non broadcasting router in my home and stock 3588 on my gtab. Did the connection once when I bought the tab and it has been connecting just fine for couple months now!

So not even close to true
Using a non-broadcast SSID as a security measure is probably the weakest (well...next to no encryption at all) method available.

Using a Linux PC, I can see ALL available wireless APs with this command:
Code:
iwlist wlan0 scan
Hiding the SSID is not even considered to be a security option, it is that poor. Save yourself some trouble and let it broadcast the SSID.
Following on from my investigations on why the SGS2 takes *so" long to re-establish a WiFi connection, it now seems part of the problem is a major delay in obtaining an IP address.
In another thread (I forget which one) it was suggested that slow WiFi could be caused by a router not being able to cope with 802.11b, g & n traffic at the same time, which got me thinking - what if I disable the n part of the WiFi on the phone to revert it to 802.11g - would this make acquisition time on an older router faster?
So - does anyone know which file / script etc. could be altered to keep WiFi enabled, but ONLY at 802.11g; not utilising 802.11n?

Just a guess, but is likely a build.prop tweak
Is this a frequent problem ? Has never happend here
Sent from my GT-I9100 using XDA App
As I've said in my post on the general forum, I get a horrible delay every time I ask the phone to connect WiFi.
I've got the WiFi sleep policy set to "when screen turns off" to save battery power; and using the same router as on my SGS (hell, i can sit the phones next to each other to try this) I get the following:
Waking the SGS up from a sleep results in a delay of 1 or 2 seconds before WiFi connects.
Doing the same with the SGS2 results in a delay of up to 1 minute before WiFi will connect. (sometimes it can be seen to give up trying to acquire an IP address, then try again)
...so yes, may be a router issue, but clearly there's something different between the 2.3.3. on the SGS versus the 2.3.3 on the SGS2 as well.
You could just disable n mode on your router if you think mixed mode is slowing it down. Most new routers will let you choose which wifi modes to broadcast via their web interface. The best option would be to only use n if all your devices support n.

Router only supports g. I'm suspecting the phone looks to n first, hence my interest in disabling it.

quick side note, wifi sleep policy set to NEVER saves you much more battery power because when it switches over to 3g, 3g uses way more power than just leaving it on wifi. counter intuitive but true.
Have you tried hard coding an IP address on the S2?
And by Hard coding, he means manually setting a Static IP address and now allowing the DHCP to provide you an IP address each time. Although the IP will most likely be the same while using DHCP, it has to request and authenticate each time. Setting a Static IP address eliminates the process of "Asking" for a IP address each time.
when the phone scans and finds the ssid, as part of that scan it checks if the router supports b/g/n then will try to connect at the highest speed. If the router isnt n compatible it wont even try.
I don't want to give the phone a static IP as I regularly visit three or four different wireless networks and they don't all use the same IP range.
I do know how DHCP works, this isn't a newbie question.
It seems definite now, watching the phone, that it tries to connect once (presumably on n), fails, then re-connects (quickly) on g.
Of course, I'll be changing the router eventually; I'm just interested in what's going on first

Understand about leaving it set for DHCP. Trying a fixed IP as a test may tell you if DHCP is part of the delay. If the b/g/n search is that slow it would be useful if it could be configured more precisely.
Have you tried it using another router using only g? If n is available it connects quickly? Seems like others would have mentioned this if it is something with the phone as g-only networks are still common.
I too am interested in disabling 802.11n. wpa_supplicant keeps hanging on some wifi networks and I suspect it may be because of n.
I am having trouble with the wifi, i was able to connect to my home connection and a mobile hotspot, but with my friends home wireless (which is working) it'll connect but not load any website/app. I'm not sure if it matters, but my home is secured with WPA and my friend is secured by WEP. but it shouldnt matter right? whats wrong?
I have already tried rebooting, re-entering password, changing modem... nothing.
What type of router your friend is using? Is it just WEP authentication or WEP + MAC ?

it is just WEP i believe, but whats the difference? i seriously dont know what could be causing the problem.
Yes it sounds weird with plain wep auth.
Are you positive you are getting an ip address from the router? Can you download terminal emulator and ping the router from your phone after connecting to wifi?

I had the same problem for a while, with my home router, then when I went into my phones wireless settings I noticed that every time I tried connecting to the router it would automatically disconnect and attempt to connect to any other connection it picked up. I rebooted the router and ever since then I have been able to connect(connection isn't always stable but whatever).
I should also add if its a Linksys router then you might get dropped connection...happens to me a lot...check for any interference(i.e. 2.4ghz cordless phone)

i believe his router is linksys, but there were no connection drops or anything.
after you open the terminal on your phone type "ifconfig eth0" and note the inet addr:
then type ping x.x.x.1 ( Replace the part after ping with the inet addr you got and make sure you modify last octet to .1 as that is usually your wifi routers ip address)
if you get request timed out that means the problem lies in authentication

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.

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?
