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?
Hi
I'm not sure if it's Android or Transformer prime thing.
My google data (gmail, gcal) syncs properly and immediate when i'm @home with my wifi network, but refuses to automatically sync at the office wi-fi network.
The office network is freely available to the device, i can browse the net without any problems.
Can figure it out why the sync doesn't work.
I have noticed the same issue on mine except my home network sometimes has the issue too. I have resolve it by disabling the sync and then enabling it again. This method works for a little while then it seems to go into the no new notification mode. I have to manually refresh in gmail to get my new mail to show up. It is annoying. I even send test emails to both my phone and tablet, but it will not ccome through until it feels like it or unless I manually update. My xoom does not do that.
I have a sort of similar thing. All I know is that I'll be delivering pizzas while tethered. As soon as I get home, and turn off the tethering, my tablet connects to the home WiFi and gets one or more notification noises as it if wasn't syncing the same way when tethered. The oddity is that it doesn't know I'm on a mobile connection so it isn't trying to save bandwidth. I suspect there is something in the security or ports that makes it's connections to the home network different than when tethering, or when you are at work.
I can't speak to the issue regarding tethering, but for those of you having issues at the office, this is most likely due to firewall rules. I work for a cybersecurity software company, and have been fighting for them to address this as both my phone and prime suffer from the same thing.
If you have a good relationship with your IT/Corporate security people, try bringing it up with them.

do you know if google sync services uses other than 80/443 port numbers?
Not only did I notice this same thing happening I also noticed emails I had are disappearing when not on home network and Wi-Fi tethering with my phone this is weird...... they disappear from my gmail application......
Got an s3 today from radioshack. I had an S2 before. I went home and tried to connect to wifi like I normally do. I use WPA2 Personal TKIP+AES encryption with MAC filtering enabled so only devices I know about can connect on my WiFi (friends were jerks and I needed a way to control who gets on.) Anyway, I added the Mac address to the list of trusted devices and tried to connect after putting in the WiFi password. I was unable to connect and the error message it gives is "authentication error occurred" "incorrect password". A bit of trouble shooting later, because i knew the password was right. I decided to disable the MAC filtering for a moment to see if I could connect. I was able to connect, but as soon as i enabled the MAC filtering it disconnected with the same error.
My Question is, is there a way to fix this problem? Without rooting and without disabling MAC filter permanently
Things I have tried:
changing the frequency of the router tried channel 1-11 (phone only works on channel 6 with filter disabled)
changing the authentication type
removing re adding the mac address
rebooting the router
rebooting the phone
standing in-front of the router with the phone pass-phrase input
dialing *#0011# and turning off power saving on the WiFi
I assume you've double checked the mac address is correct? Ensured lower case for a-f chars? Oddly it does seem as if its an incorrect mac address.
Does your router show macs of connected devices if you turn filtering off? If so, copy / paste from there?

just wanted to update and let you guys know whats going on. I found out what the problem was, and I am currently taking steps to fix it. So the mac filtering is the problem for sure. I did not input anything wrong. I found out that because the S2 and the S3 are similar the mac address of both phones cant be added at the same time or neither device can connect to the network. I decided to root the S2 and change the Mac address so that both devices should be able to connect.
Better than rooting the S3 since i dont have insurance on it.
anyway hope this update helps someone else who has the same problem.
I travel a lot for work from the US to China. In the past, I've utilized wi-fi calling on my LG G4 on Sprint for texts / voice capabilities. Sprint doesn't allow wifi calling in China, but there was an easy work around: I would VPN to a US based location (needed to access anything google), connect to a wifi network, turn on global roaming and then use a fake GPS locator app set to somewhere in the US. When used in tandem, I was able to to connect to wifi calling just as if I was in the states. I've done this successfully for the past six trips to China over the past year, but my most recent trip to China this method no longer worked.
When trying to authenticate wifi calling, it times out and gives an notification error in the status bar "wifi calling is not allowed in this country". I believe Sprint does its locating via Google (one of the main reasons wifi calling doesn't work here) but that shouldn't be an issue if I have VPN access and can utilize the suite of my other Gapps. During the timeout, sometimes I get a redirect to the following site:
http://clients3.google.com/generate_204. Does anyone know what may have changed in the past two months in regards to this verification?
Once I left China, I was able to successfully connect to wifi calling in both Hong Kong and back in the US without any issue. I believe the root of the issue is somehow the location verification has changed and I can't figure out how to properly spoof my location while in China. I've tried different fake GPS apps (need to turn on mock locations), so that's not the issue, but something to do with the network verification. I know the VPN is working because I can access all my other google apps.
Thanks for all your input!

I'm connecting to wifi to my GL. Inet mobile router which is connected to a US private VPN (own server). I don't use VPN on the phone, nor do I use a location spoofer.
Always worked for me. Phone thinks its in the USA.
Apologies for necroposting, but how do you get around your home carrier trying to connect to a tower in the other country while roaming?
Also, what app do you spoof GPS? I'm a bit reluctant to download a random GPS app off the playstore.
I have an LG G4 running stock Android 6. Been using the stock email client for years to connect to a google hosted email account, via their imap servers.
All of a sudden I get intermittent connectivity to imap.gmail.com over my wifi connection. The message 'The server is unavailable. Please try again" comes up all the time. If I turn on the Private Internet Access VPN the phoen connects fine, if I turn on cellular data - it connects fine.
I ran a trace route on the phone to imap.gmail.com and it gave me one hop which resolved to a Verizon host.
My desktop connects to the same servers and have not had email issues with it, seems isolated to the phone. So my thought is that there is not anything wrong with my local network here. The rest of the apps seem to work ok on the phone, so it doesn't seem to be a global wifi issue.
Any thoughts on further testing or ideas on what to try?
Some more diagnosis steps.
I installed K9 mail and it works fine.
I tried the native mail client app on another wifi connection without VPN and it worked.
I changed from imap.gmail.com to imap.googlemail.com and get the same result.
I am running out of ideas on things to check, beginning to think that I need to do another factory reset and see if that fixes the problem. Unless there is someway to adjust server timeout settings on the native client.
