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?
This has been plaguing me for a few days now and I just want to share the solution I found for you guys. Have you ever had this issue? Your selected wireless network has been working great for days and suddenly one day it refuses to connect anymore. I would hit connect and the phone would be stuck in a "Obtaining IP address from WIFINETWORK" "Disconnected" "Scanning" cycle and so forth. You can wait forever and the phone will never connect to wifi.
The first time this happened to me I did a hard reset. Worked like a charm, I was able to use the network again for a few days until it began happening again. I decided a reset was not the solution so I looked for an answer. I happened upon sites like this:
http://anxiousnut.wordpress.com/201...d-obtaining-ip-address-wifi-issue-workaround/
Where certain solutions were posted but none seemed to work for me. I decided that it definitely wasn't my router (although some said resetting your wireless router may also work sometimes).
I finally stumbled upon the answer. The solution is to use a static ip by going into to Settings>Wireless & Networks>Wi-Fi settings>Menu Click to Advanced and then check Use static IP. You must figure out these values: IP Address, Gateway, Netmask, DNS 1, DNS 2.... Luckily, it is pretty easy.
IP ADDRESS
To find this, go back and select your wifi network. Hit "Modify" and see the IP address listed. Copy that down, this is your IP Address.
GATEWAY
This is your router's IP address. You will need a computer that is connected to the network already. For Windows, run a command prompt and type ipconfig to show you the default gateway address. For Mac, go to the network preference pane in system preferences. Click advanced and go to TCP/IP tab.
NETMASK
You will find this in the previous step. Often it is 255.255.255.0.
DNS 1
Put in the same IP you found for the gateway box.
DNS 2
Same as above.
In the end it will look something like this:
IP Address: 192.168.1.107
Gateway: 192.168.1.1
Netmask: 255.255.255.0
DNS 1: 192.168.1.1
DNS 2: 192.168.1.1
Connect again and it works. No need to factory reset. Enjoy!
Update: After a few days, something in the phone's wifi settings seem to "correct" itself and your wifi will not work with this method anymore. Simply go back and disable static IP and your phone will be back to its old self again. If the symptoms appear again, you can follow these steps again.

thanks solved my problem i m so very grateful
Careful, this "fix" could be very temporary... If you set a static IP and do not configure your router to use static IPs you will at some point run into conflicting IPs if you have other devices on the network. The router is dynamically allocating IP addresses if you use a standard DHCP setup and can give your chosen IP for your phone to any device on the network, creating a situation when you cannot connect or you can connect but it does not work. If you want to use static ips on your phone with the router, you have to configure the router to understand this by disabling DHCP and setting up static IPs for all devices or by allocating fixed IP for certain MAC addresses. SO either setup both your phone and router to use a static IP or change the DHCP lease time to something other than "infinity" .
Most routers strart DHCP allocation at .100. Check with your particular routers manual. If you assign the IP less than .100 you should be fine as long as you don't assign another device with the same IP.

I'm with DigitalMD - this is a very kludgy "fix" that will lead to trouble in the future. I am coming to believe there is a consistent interoperability issue between Android and some other systems (OS X and some routers??) that leads to issues - both my GN with 4.0.4 and my JetStream with 3.1 will routinely fail to connect both to my Mac (10.7) and the routers, primarily in a couple of particular offices - maybe it's just a high-noise area (one is an older building). The devices both connect fine to my home wifi (WRT54G) and most internet cafes.
Not a good fix
This isn't really a fix for the problem. I connect to multiple wireless networks, between work and home and friend's houses, and they all have different routers. Setting a static IP is impractical, because I have to turn it on with certain networks and off with other networks, or change the static IP from one router to another.
Why does this happen? It works fine for a while, then one day it just doesn't want to take an IP address from the router. For me, it works fine at home and at my parents, but at work, it doesn't want to connect anymore. It's been connecting fine for months, then yesterday it got stuck with obtaining IP.
Setting a static IP isn't a solution; it's a cop-out. Does anybody know why this happens? Does anybody know how to fix it?
I was experiencing this from past couple of days than I just put static IP works really great for me :laugh: it was a biggest headache, now past.
I am currently on Genesis3D v6.1 ICS sense 3.6, everything is perfect except wifi. It could be turn on,it can successful search wifi, it can connect to any hot spot, and succesully get ip address, however the internet is not transmitting any data. I tried quite few different internet router (public and private ) I still cannot access internet through wifi. Any one has idea about what's going on?:angel:
Check what ip yer getting at home. I had a similar issue with wifi. Turns out it had some weird ip address. I assigned a static, rebooted and runs great...
It's most likely the router. Also, depending on Internet provider, the modem could be at fault. Comcast does something stupid where new devices connected are blocked or something. I have had other people's laptops connect to my wifi but be denied Internet access. Have to reset the modem and router or something stupid to connect the first time.

I used static ip at home, I am sure the ip address is correct, it is in the same ip domain as my computer. it is not a wired ip address.

I dont think it is the router, I tried different routers, and I also tried public hotspot. all the wifi I tried does not work. however, the IP address issued to my phone is totally good.
I have the same problem with every sense 3.6 ROM, and with Sense 4.0 or 3.0 (with GB) works perfectly...
Anyone knows how to solve it, please?
I had the same problem only when using a static IP address.
Changing the subnet mask to 32 (although 32 stands for 255.255.255.255 and is obviously wrong) worked for me

Hello guys, i have a problem about connecting to wifi. I have been using the same ROM for a year, but since this morning i have a problem on connecting to the wifi, it says Obtaining ip address but it just never ends. I changed the ROM two times today, nothing has changed. I think the problem might me caused by the wifi antenna itself just because it's old (bought the device two years back), but i mostly believe in it's an inner software error, if there is a possibility about it's a software error can you help me to find out what it is and fix it?
Thank you (Device-> YP-G70)
FIGURED OUT HOPE THIS HELPS ALL OF YOU:
Use static ip on wifi settings, and as ip address i don't know if this works in all countries but enter 192.168.1. (some value between 1 and 200) as gateway enter 192.168.1.1 and as netmask you can use 255.255.255.0 this solved my problem thanks

I tried that way and it didn't work out but finally i figured out what happened, i had the same problem a month ago on all my computers and tablets and phones they didn't connect to my wifi so i entered other ip adresses gateways etc. that i found on a webpage and they connected, the thing is i found the ip online and when you enter it on two devices working on same network it will discconnect one of the devices, does anyone know where can i find more alternatie ips' like that? Hope that will be helpful to the friends who has obtaining ip address loop problem.

Let me see if I understand what you're trying to do. You have multiple devices, not just your YP-G70, connected to a router. The router is distributing IP's, some of which are static, some of which are DHCP. The key is to make the router assign static IP's outside the DHCP range.
For instance, if your router has a gateway 192.168.1.1 with a subnet mask of 255.255.255.0, that gives you 254 addresses to choose from. Typically, the DHCP range is fifty addresses, from 192.168.1.100 to 192.168.1.149. So long as you assign your static IP's outside the range of .100 to .149, you should have no conflicts. I generally assign printers, NAS, other services lower IP's. 192.168.1.4 might be a printer. 192.168.1.6 might be a PogoPlug. Desktops/laptops with static IP's might be in a range of 192.168.1.20 to 192.168.1.40. Tablets and phones might be from .60 to .80. When friends and extended family visit and want to borrow some wifi or ethernet, they use the DHCP range -- .100 to .149.
Make sure to use the most secure method for wifi available on the router, usually WPA2 Personal (PSK) + TKIP / AES. Give your friends the random-10-digit-or-more-character password you created to keep your wifi secure, and they're in. If you have trouble getting in, delete the saved wifi connection to your router in the network connections area on the YP-G70 and recreate it. You should be in.
Did you changed your router before? I had same problem AFTER changed my router (from old router linksys 54mbps mode 11b/g, now using tp-link 300 mbps mode 11b/g/n)... i've tried several type and brand (tp-link, tenda etc.), same results. My assumption for now, YP-G70 is not compatible with router above 54mbps or mode above G.
Just my two cents.

On a lark, I set my ASUS RT-N16 router using tomato-USB firmware to N-only. I am assuredly connected via my YP-G70. Samsung bills the YP-G70 as b/g/n compatible. Perhaps the problem is with one or more specific router models?

Hi!
I just got my new Honor 7 and I'm now experiencing a major flaw: I can connect to my WIFI, but won't get Internet connection.
Details:
- Wifi router supports 2.4Ghz and 5Ghz, same error on both.
- IP Configuration (DNS, Gateway, DHCP) set to same as on Laptop and other android devices - all other devices working fine
- When connected to Wifi, Phone can be pinged by other devices & phone can ping other devices
- Phone cannot ping the router but is shown in it's "connected devices" list (correct MAC adress and everything)
- When opening a Wifi Hotspot from my Notebook (forwarding the router's wifi), Phone can connect to internet & ping router (everything works perfectly)
How is it possible that if my Notebook forwards the router's wifi everything works perfect but I can't get it working by connecting directly?
Hope any of you can help me with my problem!
Best regards
Do you use a MAC filter? Sounds like your router blocks the connection.

Nope, no MAC-Filter in use!
As i said the device gets listet among all other (working) devices in the router's DHCP devices list...
Sounds like a router issue. Any way to check if WiFi works on somebody else's WiFi? Suggest maybe change channels that WiFi is transmitting on the router

\\EDIT: Both Networks at my University work fine.
Is your subnet mask 255.255.255.0 or something else for the gateway? This affects the network prefix length. Also check DNS, try static setting instead of dhcp and use Google DNS 8.8.8.8 and 8.8.4.4

I noticed that when I do an arp scan for the network, I can find other devices but not the router. On my old phone the router will show up on arp scan!
If router can see phone, then assign it static IP address, then add that IP address to DMZ - that way it's fully open. Sadly with routers it's a matter of narrowing down the problem with trial and error to resolve. You can also try temporarily deactivating firewall, and/or temporarily removing WiFi security to see if any difference.

Router can see phone! I have just added it's temporary IP as DMZ Host to check whether it solves the problem - and it does!
When the phone is set as DMZ Host in the router it can ping the router and connect to the internet (so far it seems like any other device).
Before setting the static IP and using this method permanently, I'd like to ask if this causes any changes to other users in the Network ? I am sharing the router with two other people using it for phones, tablets, IPTV etc.
I'm sorry I have no idea what DMZ is exactly.
Thank you very much for your help so far!
No problem. It's not really a permanent solution as it just opens up the IP address to all traffic. It does mean that the router is somehow blocking the phone in normal conditions. This could be for all sorts of reasons, firewall rules on the router, or port forwarding, or Mac filtering, or IP filtering, difficult to say. DMZ shouldn't affect the other users.

I'm not too sure about this router's configuration because it is a rather cheap NoName device provided by the ISP while at my home I'm used to AVM devices.
But I can nowhere spot any specific rules, there's not even a single port-forwarding set on the device. So I can't spot anything that could be blocking my phone :.
Anyway I have just removed my phone from DMZ, reconnected it to the Wifi and so far it's still working fine!
Even if I have to re-do this procedure every now and then after device reboots it shouldn't be a problem.
I have no Idea on how temporary setting it up as DMZ haschanged everything, but for now I'd consider the issue solved! I owe you one for this

Tested all 10 channels but still no internet.
Also tested disabling the WPA/WPA2 PSK safety but same result.
Put it in DMZ, find DHCP table and see which IP adress phone get, put that adress in DMZ, DMZ settings are on the same place as NAT (usually). I think that phone cannot get DNS server from router because of some rule in firewall, but try to ping 8.8.8.8 from phone without setting up DMZ, if DNS is problem he should ping that adress but not be able to load page in browser....
@ MaxMonument94 can u connect to any other Wifi ? or all having same issue ?
The internet connection is working in any other network exept the network at my girlfriends place but she has the same router/provider as i have.
If there are any german users, we both got “telecolumbus“ as internet provider.
Now its just more curious.
After i entered the IP in DMZ my ookla speedtest on my phone showed perfect results.
Also the Chrome browser loaded pages and other apps (like 9GAG, Telegram, Whatsapp) worked for a while without any problem.But after a while they all got connection problems (page dont load, waiting for connection on telegram, GIFs dont load).
After that i started a new speedtest and the results were again quite good.
Then the same procedure again and again.
I have really no clue what kind of problem that is.
Btw: my mobile internet was disabled all the time to dont distort the results.
When that happens again, try to ping 8.8.8.8 and tell me what is output, remember ping it when it wont work....
I have pinged 8.8.8.8 with Android Terminal Emulator
The results in the screenshot.
