hmm, that's kinda weird as my SGS I9000 didn't experienced any WIFI problem either since in eclaire or Froyo.
now i use Firmware DXJPA (Froyo Region : SEA)

Very similar issues in reconnecting with the Wi-Fi router once you go out of range and return for Samsung Galaxy Tab too.
Resolved it in a similar fashion by selecting a Static IP.

Hey,

I read you post and entered the same IP address settings using static IP as i use on my laptop for wifi.

I still cannot connect to the internet on my Samsung galaxy s. Please help resolve this issue.

Thank You,

i read this and apply the settings ysterday and then the problem resolved but now 2dy again a new problem arises that wifi is showing connected and no response on internet or market my laptop by which i am posting this comment is on same network and its working great but phone is showing only simble of wifi connected

In my Aztech 550 3G router the place for secondary DNS is blank,Primary DNS is 192.168.2.1.
So can I leave this space blank in the Galaxy?

PERFECT! WORKED LIKE A CHARM! I WAS GETTING TIRED OF RESETTING TO FACTORY DEFAULTS AND LOOSING ALL MY INSTALLED APPS! THANKS A LOT!

nice and easy setup and pics Thanks

Thanks!!!!
It Work!!!!

Thanks for this guide. I've searched numerous forums and tried installing some wifi fix apps - all without success. Following above instructions fixed the problem on my Galaxy S at once. Thanx pal!

Brilliant!! Thank you. Great phone but Wi-Fi used to work but then no connection . Secured but disconnecting all the time.Really serious problem spent hours checking phone ....would never scrub phone or do anything drastic. Persistence in reading up problem found this great site. : MegaLeecher.Net. Followed Your Brilliant screens Galaxy phone, on the advanced button in Wi-Fi...... all my IP settings were missing including all the 192.168.....etc settings . Don't know where they all went or if an app. deleted them as app. say they can change your phone settings.I set up all the numbers exactly as shown above . Double checked them ...one was incorrect and I entered correction.
Went back to Wireless connection setting picked Wi-Fi connected immediately.

Thanks again !!!!

Hi,

My phone has worked for weeks and then suddenly 2 days ago will not connect to wifi. I have followed your steps above and still keep getting the same message "unable to scan network". It then instantly switches wifi off, the only thing i can see different on my phone is that is saying MAC Address "unavailable". How do i find out what this should be?

Thanks

I try the setup of a fixed IP on my mobile too, but it is not working at all :-( I can connect to the WIFI, all data inside like ip and so on are correct, but i cant go into the internet.
I can open the router page in my mobile and i can ping the mobile from the router ... with both ways - fix IP or dynamic, its no difference ....

But i will not surf on my router :-)

It was working perfect before and with my mobile connection its still perfect working but suddenly not by wifi anymore .... :-((

Anybody have an idea ?????

Thanks in advance !!

I read it, but I have problem at step 1, I can't turn wifi connection On, it says "error"...what does it mean?????

Guys

Fixed IP address need some more network adjustments to work fine:

1) That IP must be reserved on your router so the router dont assign that IP to any other network device

2) That IP must be in the same network mask of your router so that example you gave will not work on every router unless you change the router LAN parameters

3) With a fixed IP address when you walk out and try to connect to a different WiFi (airport, office, etc) your chances to find a net with that exact configuration is very low and if you do, still need to be lucky enough to find that IP address free for you

Fixed IP configuration will only work on your home network if you make sure points 1 and 2 are set for you

My 2 cents

If it could be configured like ip/net/rtr per wifinetwork it could be correct. But it is global to ANY wifi connection so or You have only one wifi network or You must rewrite ip/net/rtr every time.

So this info is useless for anyone who want to have its phone mobile ( :-D )

Samsung does not know why such things happens.

Hi, GalaxyS Men !!!

The games with fixing IP adress on our GT-I9000 may result to damage of system file "bcm_supp.conf" in Android system directory "/data/wifi/". And our lovely device never be able to connect to WIFI-nets. If we want to reanimate our WIFI, this file must be deleted (http://forum.xda-developers.com/showthread.php?p=7947523#post7947523). It is a problem. The thing is that access to system area is closed. Therefore We need Root access to i9000. Or reset to factory defaults and all personal setiings will be lost...I checked this issue on myself.
May The Force be with all Galaxy Jedi Knigths!!!

Thank you so much

i just recently updated my firmware from android 2.3.4 to 2.3.6, i was always pretty scared for problems because my phone runned just fine. but when i did update it i got a problem with the wifi. it lost its signal and switched from wifi to 3G+. but thanks to your great tutorial my phone is saved from a fatal fall from 11 high XD

thank man

i was wondering why my iphone keeps disconnecting my wifi from time to time . never knew there is advanced settings under the wifi option :) thxxx alot i fixed it and it works great ... u are the best

Hi am using Galaxy 3 i5801. it has been found MAC address unavailable on my WiFi settings, may i know how to rectify and input MAC address

Working perfectly for me..... thank you very much

Great job! Well explained and easy to follow procedure. After updating my router's IP address, immediately got connected. Only problem is you can only browse from your home router which means if you find yourself in any open wifi, may no be able to connect from there.
Any help or go round on this?

oh man thanks a lot it worked perfectly for my i had kind of the same wifi problem only that when i switched the wifi on in my samsung captivate it would stay there forever trying to connect to my router and i just used the same values that you used and it worked perfectly for the record i have a linksys router and i had to leave the wifi switched off when i was changing the values in the advanced settings and then turn it on with all set up as told here and worked once more thnks

worked perfectly for me thanks

Thank you it worked for me

God Bless YOU.

in my samsung galaxy y duos lite wifi connected but iam unable to browse the internet....
what can i do now?
please help me

Tried the above and does not solve my problem which is:

Everything has worked perfectly since I bought the phone, until this week when my browser keeps saying: "web page not available" when trying to connect via my home wifi.

Browser works perfectly via phone network data link but NOT via my wifi. Absolutely everything else works via wifi including all apps and email.

Wifi (router) is working perfectly - PC and netbook are connecting perfectly.

one of my friend is connected to wifi through static ip. I copy the same data for my static ip setup, but it doesn't work. becauase after entering all the data the connect option is greyed out, i have SG3 witth 4.04

Further to my last post, I can now confirm that my browser is not working with any wifi router or hotspot.

I would like to thank you so much for solving the WiFi issue with my Galaxy S. The fixed IP solution worked for me. I did need to switch off and on my WiFi again to finaly solve the issue, but my internet via WiFi is fast again and also my phone seems to act faster in general.

i read this and apply the settings ysterday and then the problem resolved but now 2dy again a new problem arises that wifi is showing connected and no response on internet or market my laptop by which i am posting this comment is on same network and its working great but phone is showing only simble of wifi connected

I have followed the above steps and internet started working but only in default browser(Internet ; because here it is asking for username and password), and rest apps including opera mini are not working.
Model : Samsung Ace-S5830i

I HAVE SPENT 45 MINS TO FIND OUT THE PROBLEMS ON MY SAMSUNG GALAXY S+. IF YOU HAVE A BELKIN ROUTER.. YOU JUST NEED TO: RUN CMD OR COMMAND PROMPT... TYPE ipconfig .... THEN LOCATE THE "GATEWAY" OF COURSE IT STARTS USUALLY FROM 192.168.... (MINE WAS 192.168.2.1)... THEN USING THAT IP ADDRESS OR GATEWAY NUMBER.. GO TO YOUR WEB BROWSER. ANY BROWSER WILL DO AND PASTE IT ON... YOU WILL THEN SEE THE BELKIN ROUTER SET UP... LOG IN USING UR PASSWORD... I HOPE YOU DO KNOW THE INFO.. AFTER LOG IN.. GO TO "channel and SSID" TRY TO CHANGE THE CHANNEL FROM AUTO TO CHANNEL 13.. CLICK APPLY CHANGES... AND YOUR GOOD TO GO.. NO NEED FOR SOME ROOTINGS AND WASHING YOUR PHONE'S FILES AWAY... HOPE IT HELPS..

Thanks heaps - typed in the same values as you and working fine now.

Very effective ways! I believe Samsung Galaxy I9000 users are being finding this post helpful whoever is facing that similar problem with networking.

I don't know why people are praising this solution so much. Here I'm sitting biting my fingers on a Galaxy S SHW-M110S (Korean) which is refusing to even identify the networks that are being picked up by laptop and my htc. Same holds good for the GPS signals. I'm repenting having bought this useless phone

Yay!!! It worked. THANKS

I've been trying to get the above settings done on my GT-I9000; but for some reason the above has not worked for me. For some reason the Wifi symbol does not get activated.

My Phone had issues and kept restarting so had done a factory restore before i tried out the above.

Is there any other solution? Your inputs will be valuable to me...

THANK YOU SO MUCH!!

Hi im wondering how to solve my problem . My wifi is turning on but for another minute it wont work its still disabled and i look at the ip address it is 'unavailable' pls help me i want to use my wifi . My phone is samsung galaxy duos pls help

Wow Man U Rock . . . .problem is solved thanks alot dude keep it up . . . :)

plzzzzzzz help me to giv answer

I have done all the settings as you discuss but still its not working.
Wifi signals shows but no access of internet!
can you help me with that please?

This is not a fix, it is a workaround. How do you know the ip address for public locations like starbucks or hotels? Google is clogged up with these so called "solutions". If you label it as a workaround people don't have to sift through gb's of crap to find the real answer.

Having said that, it is a good workaround for your home network.

i tried the steps above.
the addresses i typed were the exact thing as in my laptop's wifi connection.
it only says it's connected but you can't use the internet at all, facebook and viber notifications doesn't come up as a result.
my cellphone is like useless now when it comes to internet connections, i'm gonna buy a new phone next year and i won't be Samsung, that's for sure.

Thanks friend my connectivity problem got fix...
Keep it up!!!

GMX

I went to samsung service center for two times and no resolution and now you gave me the PERFECT solution......thank you so much yaar....!!!
