[Q] Wifi - problems.. - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi,
let me thank you for all the help you may give me.
The problem is i get stuck on obtaining ip address or the cell doesn't even try to connect automatically so i have to manually start the wifi connection to the network after turning on wifi.
The problem of my SGS not connecting automatically is rare, the first is not, it's actually quite often.
I looked through all the guides and sugestions but i couldn't find any permanent solution for this problem.
Note: I've used the AllShare app but sometimes even that doesn't work.
Thank you for all help

The same problem kept happening with me. Some of the fixes which I tried were
Change channel on router - didnt work for me
Use the allshare app first - worked
Set up a static ip in advanced settings - almost always worked
But I have found that I didnt have this problem with other routers, only mine, maybe because of a power problem with the router.
Many of baffling errors are usually caused by bad input power to devices.
Hope it helps

Thanks for the reply, the problem is that i use it alot on my university, where i can't do any changes to their router (or use static IP).
Also the AllShare app is indeed a fix, but only if used every time i think. I'll do some more testing, this problem is really annoying and that's a shame because it complicates the use of most of the smartphone capabilities.
So if anyone else as another solution i would be glad to hear it.
Also i'm on stock rom installed by my operator Vodafone (had the same problem on JPY).
Edit: After a very quick test, it seems that using Allshare once does work, but i had the impression that sometimes it would be needed more than once (even without rebooting). TY for the tip.

Update:
After some more tests i came to the conclusion that at home i need to use AllShare every time i want to connect to my network.
This seems to be a problem affecting several users of SGS, does anyone know the answer to this problem? Or at least an app that minimizes it?
It's quite bad and very frustrating. Thanks, for any and all help.

I had the same problem with stock Android 2.2.1 on 3 phones all Galaxy S. Dropping the packages on voip calling, internet was slow most of the time. I use a linksys wrt54g with dd-wrt, I never had problems with any other devices.
My problem was solved when I installed GingerReal. Also on Miui I didn't had any problems with the wifi connection.
Maybe is just the stock driver incompatibility with some devices.

Thanks for the reply,
I've only had bad experiences with flashing, last time i did everytime right and Odin just hanged, i almost had a serious problem in my hands.
Since this is probably the first and last good phone i'll ever have, i would really like not to kill it (also some people in my family would be very disappointed, it was a gift).
So any workaround? Sorry i'm so insistent but i think that are a lot more people interested in this. TY.

[Q] wifi problem (azusaROM 1.04.29062010)

hi, I bought a second hand tattoo last month, the previous owner installed azusa 1.03 on it but wifi didn't work at all (I was able to switch on the wifi) So I flashed with the last Azusa ROM (1.04).
first the wireless worked fine, but, I think after a reboot, the phone wasn't able to get IP address on every AP I tried. however I can connect a wireless network if I set a static IP on the phone...
any idea to fix this, please?
(sorry if it's a problem to post it a second time, but I don't know if the problem come from the ROM or not...)
Well, I have the same problem with the wifi. It sucks cause this rom is really fast and non-functional wifi is the only deal beaker... Try to contact the developer Coburn and ask him. If you reach him, tell him that I already posted a log of the problem on the project's site.

Any news on this? I really like the ROM but not having wi-fi completely kills it =\
None so far... And I doubt that there ever will be a fix for the issue. I abandoned this Rom.
hi, I didn't find a real solution for my problem... I just installed an app named "wifi static" and I set the few network config I use usually, it works, but I can't connect to any free hotspot easily.

[Q] Problem with WiFi

Hi!
I have a really weird problem with my SGS.
When I'm installing ANY firmware (I've tried every single one) except of my original FW "JPB", I can't get my WiFi working.
There are actually 2 types of Wifi behavior on the different ROMs. The first one is when you're connecting to the Wifi and you can actually open Google.com, Android Market, etc, normally. But when it comes to a "heavy" sites such as youtube, wifi connection just freezes and nothing helps before you'll close the browser and reconnect to the access point.
On some other roms you're connecting to Wifi without any errors too, but you can't actually open any site at all. And only on FW "JPB" (which is russian official) there is no such a problem.
Also Samsung Apps doesn't work on other ROMs, I even thought that it can be related somehow... I know that there's no logic here, so I'm really confused.
Oh, and even if I'm installing Voodoo lagfix on my official firmware I'm still getting into this trouble
I really want to hear your opinion, so please don't hesitate to reply.
Thanks in advance,
Jay

[Q] WiFi occasionally 'killing' routers

Search function is currently unavailable, so apologies if this is a dupe...
Anyways, I'm currently running Rooted Stock 2.3.4 on my N1, and I've noticed that whenever I connect to my friend's DLink router (DIR-655, I think) the Wireless will work for some amount of time, but eventually it will stop working. And not just on my phone, either - the entire router stops working (at least for Wireless requests. Didn't have any wired devices connected to it). Thing is, last time I noticed it, it worked for quite a while - hour or two, maybe - then everything broke about 10 minutes after I received an email... At that point, the router needs to be rebooted, after which it continues working just fine.
The router is using WPA2 encryption, for what it's worth.
I've noticed this with previous versions of Android, so it's not a breaking change introduced with 2.3.4 or anything.
Unfortunately, I don't have an awful lot of Wireless routers to test with, and I haven't yet found an opportunity to test at home, so I'd be hard-pressed to say whether it's a router/D-Link problem, or if it's a device problem...
Has anyone else experienced this? Would flashing a custom ROM (e.g. CM7) fix this? Or would I need a new device? Any thoughts on what else I could do to debug this problem? As I said, this is a rooted device, with an unlocked bootloader and the latest version of Busybox installed.
I'm running 2.3.4 and haven't had this issue with this version or any previous ones.
I've had my phone disconnect from Google Services (the icons turn white instead of green), but the internet stays on and all other devices work just fine.
I have a Netgear router at home and a Linksys one at work and I'm connected to both the whole time I'm at either place.
Hmm... That's interesting.
I've never had Google Services disconnect, but I do have another issue with data randomly turning off. That's not a big deal, as I can just turn it actually off then back on again, and all is good.
Anyone else able to chime in with their experiences?
I have had this happen with cheap, crappy routers. Sometimes upgrading the router to DD-WRT helps, sometimes it doesn't. I had an ASUS this would happen to all the time, and an Airlink that this would happen to occasionally.
This doesn't ever happen to my Linksys WRT610N, and it never happened to an old ZyXEL X550.
I'm going to say, it's just a crappy router.
Thanks. Not really what I was hoping to hear, but that's life.
Did either bad router ever have this issue with other devices? One of the other folks living there has an iPad, and never has this issue, so I'm inclined to say it's at least partly my N1s fault. Also doesn't happen with any of the PCs connected to it.
Yeah, they actually did occasionally have issues with other devices. Hard to narrow it down because I have a ton of Wifi devices. The ASUS also seemed to go down based on time... after so long, it would just stop working properly. The Airlink seemed to get stuck based on demand and range. If I had my phone or laptop at the far end of the house and started using it a lot, it would get stuck. It was as if the router decided it was too much work to pump its signal that far and it would get tired.
Stock ROM on my N1 doesn't seem to allow it, but if you have a custom ROM, you might see if there is any way to set the Wifi to G-only. I had noticed on my old router that G wireless devices seemed less demanding for it.

[Q] after update to 2.3.6,wifi can not connect

My WiFi connection has always been reliable and robust before the update to 2.3.6,but now it works wrong,the wifi is scanning repeatedly.When I try to connect my wireless,the connection button is disable.
Anyone else seeing this? Would you give me a suggestion?
Thank you!
I've had the same problem since 2.3.6 was pushed to my Nexus One. There seems to be some people with this and other serious issues, but there doesn't appear to be any acknowledgement of the problems from Google. I have read some posts by people who use their phones for their business and such, and the issues with 2.3.6 are causing them to lose time and money. I don't know why they released this, they obviously didn't test it very well.

[Q] why does wifi always die in DjangoManoucheX?

Okay guys I've got a constant problem with DMX, not just with this version, but I start to get tired of it. So after a day or two of flashing, wifi starts to stuck at "Obtaining IP address", and does not connect at all after that. As I said it's not only with this version (I'm on 1.6.5), I have also tried different kernels, etc, but it's still the same. I don't want to always reflash, but I'd also stick with this ROM as I really like it. This problem does not come up on CM-based ROMs at all. Thanks for any tips.
Btw I've also tried static/dynamic IP settings, I've changed a router (not because of this), reseted it many times, so not that I didn't try anything at all.
I never had a issue... Have you installed the rom with full wipe?
Of course I did a full wipe, didn't restore any system apps, and as I said it works perfectly for a few days, then bamm! I was playing SongPop, started a game with someone and it stopped when downloading songs.. then I went in wifi options and it showed this IP bug once again. By the way I've just finished reflashing (now without full wipe), and it doesn't even connect now. I really like flashing ROM's etc, but not the same one all over again lol.
Finally I could set static IP on my phone, works now, Thread can be closed. If anybody has the same problem (I've read I'm no the only one), then holla at me!
I'm having a wifi issue from the day i have purchased this phone my wifi always go in the sleep mode don't know why no matter which ROM i use it goes to sleep after the screen is locked or after 5-6 sec of no use of phone.
i'm the only one having this prob i guess.. I thing its an hardware issue, not sure, hope some1 could help me out ^_^
Note: i have kept wifi policy sleep never
Problems with wifi is a kernel issue.
Its adviseable to post which kernel is used
Well I wouldn't be sure, as I was using Kowalski kernel and KoB kernel too, both had the same problem, and only on DjangoManoucheX ROM. But it seems to work now with static IP set.
akash.mahadeshwar has his ROM/kernel stated in his signature, too bad I can't help you.
Lol I don't know if its hardware or software issue but changing rom or kernel dosent fixes it :-/

have you tried changing your wifi to static ip?
if not, then go into wifi settings and long press/modify the one you cannot connect to. Go to advanced settings and change from DHCP to Static IP. Run Windows commander (just type 'cmd' in the Start Menu search box), and type 'ipconfig /all'. It will show all the informations you need to type to your device's wifi settings. You can give almost any number to the first IP field (when your IP getaway is, for example 192.168.7.1, you only have to change the last number to any you want to, like 192.168.7.155.. but the best way is to get the IP number your device used before wifi got stucked). If you can't see DNS1 and DNS2 in your ipconfig, then you have to go into your router's settings (in browser), that will show them. If you type everything correctly, then Save button won't be greyed out no more, and voila. Wifi works perfectly for me since then. I hope it helps.

Changing Wi-Fi to static is far from being a solution; at best it's a workaround.
It's probably related to LG code, used to compile the module loaded by kernel.
I'm not sure if the problem you're reporting us exactly this: I have a brief disconnection/reconnection sometimes when I unlock the phone (Wi-Fi suspends policy sets as never), but this it's not annoying me to much because while sleeping it's connected, and the 2-3s after wake-up is not to much.
Do not say "thanks"; just press it under here.

No, my problem was I could not connect to my wifi AT ALL. Couldn't even do it after a full wipe and reflash, so using a static IP is a solution for me, as it works for 3 days by now. It can be related to the stock ROM's code, as CyanogenMod ROMs don't have this problem for me.
Try flashing KoB kernels again, in mine its wifi work correctly
