Help Wifi in Galaxy S

Hey guys I had the wifi drop issue on my galaxy s. I resolved it by switching my router to 802.11 b & g.

When my router was broadcasting in 'N' mode I would experience wifi dropping constantly on my galaxy s. Once I switched to B & G mode ONLY, this is when I wasn't getting dropped any longer.

You shouldn't have to do this to your router but at least the wifi connection stays connected and wont drop.

I think the android wifi package has issues with draft N frequency.
 
Hopefully you can bug report this on the samsung support website so they are aware of it. I haven't read anything about this problem anywhere else (but that doesn't mean much) I just want to make sure samsung knows so they can fix it.
I tried to report this to sammy, but all they did was send back a link to the bada developers site. Not really sure where to submit this but...
 
There is definitely a problem with galaxy s wifi software. It randomly makes wi-fi sleep without notifying the user, hence the frequent disconnection.

The solution is to plug your device, when connected to wi-fi. While charging, it doesn't need to sleep at all, hence no disconnection.
(Cross-posting to some other thread)
 
I found something unusual in galaxy s. I found that Wifi works without disconnection in the night time, but in daytime, there is frequent disconnection.
In the night time, my wifi router is not being used by any other system, whereas in the daytime, it is being used heavily by others. Can that be a problem ?
 
Hi,

I have found the issue with my galaxy s wifi. If there is any other laptop using the wifi-router, then there would certainly be a problem(20s frequent disconnection).
However, once the other laptop stops using the connection, wifi is perfectly fine.

Can other people confirm whether they are also experiencing the same ?

I do find each time I use the wifi whilst the Laptop is running it works if you load an application and use the Internet just the once. However, if you try again it often just hangs or waits continually.
The only course of action is to close down wifi on the Galaxy S and then run it again.
 
Im also having terrible issues with my captivate galaxy s. Seems to be an issue while connecting to my cisco WAP4410N at work, specifically. The wifis run all day long on my old dlink router.

Im noting some very strange issues, here are the facts:
I get the page cannot be displayed error in the browser.
I can access public sites through their IP address.
I can ping any public IP address.
I can ping any private IP address on the same subnet as the access point (10.10.2.x).
I cannot ping private IPs on a different subnet (10.10.3.x)
DNS resides on a different IP subnet, which is why I cannot browse.
The router (juniper ssg20) has no record of any sessions to a private IP address on another subnet, however it will show all sessions from the phone to public IPs.

I wonder if android is not honoring the subnet mask, and is attempting to broadcast to any and all private IPs? The settings look fine to me in the DHCP server. Also, it works fine for all laptops and my buddys droid.

And now to really play with your mind, when i manually enter the settings, it works fine. Sadly this is a problem when I go home and am on a different private network.

Just wanted to add my findings to this thread. I hope they fix the issue quickly.
I have the same f%#$!*g problem as well at work as well, it is VERY annoying. We have about 10 Cisco access points (I don't know what model) that all use the same SSID and are completely open. My Vibrant (T-Mobile) can connect to these just fine but I have the same symptoms you do. I have zero issues connecting to wifi at home with my old WRT54G v4 with Tomato firmware using WPA2.

I have a co-worker who bought a Captivate (AT&T) and he has the same problems as well so it isn't just my phone, so I am 99% sure it is a Galaxy S problem. We have no problems with other Android devices around the office. I know people who have the HTC Hero, HTC Evo, Nexus One, Motorola Droid, MyTouch 3G, and G1 and these phones can connect to our APs just fine. My old phone was a G1 and I used it from 1.0 firmware to 2.1 and didn't experience any problems either.

I'm curious, how did you find what your subnet mask was? I tried running ifconfig using the Terminal Emulator app and it was blank. I wonder if you need to be root to run it. I will investigate this problem more when I get back to work.

Ditto here. But when you stop the laptop, it works without any problem, otherwise same as yours. So it looks like we have pin-pointed the problem with galaxy s.
 
I have the same problem. Connection to the internet drops in and out. I would have to turn my wifi off and on to fix.
I have noticed that every time this occurs, my ip address is something funky. This happens even if I have a static ip set up for my phone and router.

Any ideas?
 
I hope this fixes everyone's problem

I was trying to connect my wife's new Galaxy S to our wifi and was having the same issue.

In my wireless settings on my modem (Netcomm NB6WPlus) There is a setting for "channel" I set this to 11 and the Galaxy connected immediately. Also make sure static IP is not set.

Cheers

I'm also having problems with wifi... the signal seems incredibly weak.. We have a wireless access point that has a strong connection, but the phone always shows the connection as weak.. what's the deal? could a firmware update fix this?
 
FIXED FOR ME NOW!!!
After trying everything all of you have posted here's what worked for me.
Unplug power from your modem and router for 15 seconds +. Then replug power (I read / heard once that it is important to replug these devices in the order they are connected: modem 1st then router)
 
Same problems here. I've just about tried everything, max I can get is 30mins using combination of entering IP address etc, turning off sleep and to turn 3G off. The dropping is really irritating!:mad:

I've also had my first Galaxy S exchanged for a new handset, but second one has same issues. I know my Wi-Fi network is fine as never have an issue with any other device, and I don't think it's an Android issue, more likely bad skinning by Samsung, my HTC Desire is faultless!

We have 3 Galaxy S's at our company, all have same issue.

Dear Samsung u need to fix it and fix it damn fast, these issues have been dragging on for to long (you should have done a 2.1 update fix months ago).:mad:

It's a real shame because the Galaxy is a great bit of kit, camera is awesome, but it's let down with the numerous bugs, app lag, freezing, GPS and Wi-Fi being the most irritating!

This would solve only private wifi problems. You can't unplug public wifi... I can't connect to any public wifi (but one), with or without password, and I've tried many. Not even at my workplace... I've only managed so far to connect to my home wifi without problems.
 
My brother just got his Galaxy S and when he came to my house last night and I gave him the wifi access key to my router. Today he calls me mad about the password I put on his "Internets" true story. Now after reading this I have plenty of things to try on his phone and unlock his "Internets" but I'm wondering If any of you tried removing all saved wifi connections on the phone and start from a fresh restart? Sounds like a software issue that may be patched if we squeek loud.

Ive been making a factory reset every 4 or 5 days in order to fix the wifi issue, and I also would like to know if there is any easy way to clean the saved wifi connections.

Thanks on advance for any cooperation.
 
dnubpa,
no need to reset that much to fix the wifi issue.
* to get rid off unused wifi - go to wifi set up and hold press (2 secs) the wifi you don't want anymore, then there will be 2 options pop up:
1) forget network
2)change password
---> choose the first one, it will gone

another suggestions:
* setup your network according your operator - mine is GSM only (don't use auto detect GSM/WCDMA)

* Choose your operator manually

So far, my wifi and Phone connection just fine. Can't wait for my froyo - THEN , ALL HELL BREAK LOOSE !!! YEAAAAAHHHH
 
Wow i just fixed it if your static ip is set to on turn it off and it works like a charm i think that's the problem hope it helps worked for me :)

My first post on this forum is to thank you. I was getting 'web page not available' on the home page of my new galaxy, using default browser. Worked fine in Opera. I changed static IP from ON to OFF. Works great. Oddly enough, it still works after I changed static IP from OFF to ON, where it sits now.

Either way, thx.

I have the exact problem..and ive been doing the same thing over and over again...i have been factory resetting my phone 10 times now just to access the internet through wifi.
I havent had this problem until I updated my phone to froyoX-(...

My phone can detect our router and im sure that it's not the router's fault..
whenever i click the access point, it will say "obtaining ip address " endlessly but it wont connect :
