Wifi problem - Vibrant Q&A, Help & Troubleshooting

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

[Q] connecting to a non broadcasting wifi signal

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.

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?

[Q] Wifi has connection but no internet access

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 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

S3 can connect to WIFI but no Internet

Hello everybody.
Since last saturday i'm testing a Galaxy S3.
I want to test if everything works properly before buying it.
I have some problems deling with the WIFI stuff.
I gave him a static IP (192.168.1.15), configured the gateway as the ip of my router (192.168.1.1),
the network class is 255.255.255.0 (network prefix = 24), the DNS points to the IP of the Router (192.168.1.1)
It connects without problems. form the S3 i can ping any device in my network and from other devices i can ping the S3.
I can connect to the configuration site of the router and from the page of connected devices i can see that the S3 is connected
with the correct ip and also the MAC adress is correct.
And for now everything is fine.
Problems raise up when i try to surf internet. The answer is always "Page not found"
If i open the browser and try to navigate to google] the answer is "Page not found". Same for any other site i try to connect with.
I cannot ping external adresses from the S3. Only the ones inside my LAN.
On the same LAN there are 3 laptops, 1 IPhone, 1 TV, NAS NETGEAR , home automation screen, all connected in WIFI.
All of them configured in the same way. (static ip, gateway=ip router, dns = ip router, network class 255.255.255.0),
And they all access internet without any problem.
The network is protected with WPA2/PSKey, encryption AES.
I tried to configure channel with WPA, WEP, without protection, but no changes.
The S3 connects to router but does not connect to internet,
I also tried to make it point to a public DNS 8.8.8.8. No WAY!
Works for other devices.
I tried to reset S3 to factory parameters, same thing i did for the router.
I reconfigured everything from scratch but no result.
I do not have any filtering based on IP or MAC adress on my Router.
I tried with DHCP, with reservation of IP adresses or without reservation. No change.
Other devices can access internet. S3 does not.
I have to say i'm quite desperate.
If you guys have some good ideas to solve or diagnostic the problem i would be grateful.
Cheers,
Fabio
I get that around my office as I walk around, I find that when I change AP in range my internet connection drops. I have to constantly disable/re-enable WiFi.
Even around my house, I have the handset to WiFi always on, yet when I wake up in the morning the internet connection is not working yet there is an IP. I couldn't be bothered to telnet to port 80 etc., but I hear that the Jellybean update will resolve this issue.
Same problem

[Q] My YP-G70 won't connect to wifi

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?
