[NEED HELP] DROID3 WiFi and Data connection problems [SYDNEY AUSTRALIA]

Hey so I bought a DROID3 off ebay, Unlocked ofcourse.
Its a great phone except for a few things such as no good roms and mainly that I can't get my mobile data to get working, i can call and text people Ok I think, also when I connect to my home wifi it has no connection. I think that might be a setting on the router but im not sure.
Does anyone have any ideas?
I bought a G2 before I got this phone and everything worked fine.
thanks!
I have the same issue, i can text and phone no problem. Wifi connections work great but my phone doesn't even see data over the network.
Im on mts in manitoba Canada.
Any ideas?

[Q] New Lead and Wifi Dropping like crazy

My wifi connection is dropping within seconds of connection. The phone switches to 3g, wifi turns back on and connects again for a few seconds, drops then kicks back onto 3g.
Ive had this issue on multiple roms, so I am relating it to something similar to RezRom and CleanRom or to the leak itself.
Anybody have ANY ideas?
Update: seems that after the firmware update, my router and phone did not like each other. I was able to tweak my router quite a bit and it appears that the dropping connection issue is resolved.

It is a wireless N router? I do believe I read that our phones are having issues when on the 5Ghz band.

The phone does not have 5GHz abilities, but regular 2.4Ghz N is supported.
Via Rezound using XDA Premium
EDIT: Take that back, however it doesn't see any of my 5Ghz access points here at all.
I have a wireless N router at home with no problems. It is on the 2.4ghz band though. I think.

What settings did you wind up changing? I have a similar issue with my phone and one of my routers.

Ditto. My wi-fi is dropping intermittently. If I toggle it off and back on, it starts working again.
What router tweaks did you do or phone tweaks?
My rezound picks up N 5ghz just fine.

I'm having the same problem. However, mine doesn't drop out within seconds, it'll probably be good for a couple hours then I'll notice it's trying to sync with my Exchange server for a while, and will eventually time out and then I lose all internet connectivity until I turn wifi off and back on again. This happens on multiple wifi networks, including wireless-N and non wireless-N.
I do also see that the 3g icon will come and go every few seconds when connected to wifi. Anyone know if this is just a bug with the new ICS leak or is there some kind of fix floating around?

I am unlocked and rooted but I am running the stock ROM and mine does exactly what yours is doing. I don't actually know if this happens outside of my house since I'm generally using 3/4G then.
I have a thread on this in the question section but no answers yet.

This is true. The rezound does seem to have 5ghz capability. However my POS netgear doesnt get the same distance on 5ghz as 2.4ghz.
As far as what I did was actually reset my router and update firmware. This seems to have fixed the issue for now. I only started having this issue with the updated leak and it was happening on all roms and even stock. Reinstalling a ROM would fix it for about 2 to 3 minutes then it was back to switching between both data and wifi.
My phone burned up the battery in a matter of an hour and half as it was constantly going from wifi to 3g.
My phone does the same thing!! I think it happpened when I flashed the new leak zip without re locking vootkoader. In hoping that official ics will fix it

Just curious if anyone found a solid solution to the Wifi problem that we seem to be experiencing with the new leak? I tried the suggestion of disabling auto wifi in the dock mode but that didn't seem to fix it for me. I guess I'm just trying to see if this is widespread, or if it's only affecting certain people in different scenarios. It doesn't seem to be getting as much attention as the overheating/battery life issues that others are reporting.
So far I've tried connecting to multiple networks with different security types (open, wpa, wpa2, wep) all seem to the have the same result of showing that wifi is connected, works for a couple of hours, then will lose wifi connectivity, even though the wifi indicator is showing that it's connected. I've done everything i can think of other than re-flashing the ICS leak. I've also never unlocked my phone, just installed the update per the original instructions on Android Police.

[Q] Samsung Galaxy S3 Data freeze.

Hi,
I'm new to the forum so apologise in advance if this is a stupid question.
I recently bought a Sim Free S3. I haven't rooted it as i'm quite happy with the stock os for now. Everything had been working very smoothly on it. But since getting the over the air update for it my data signal randomly drops out or freezes. It seems to do it over WiFi too. It does this even though it shows a wifi connection or with the H+ visible. I've also noticed it cycle through H+ to 3G and back again.
Sometimes the signal works again on it's own and other times i have to switch the phone off and on aain.
I find it happens on tweakdeck the most but has also happened whilst browsing the net.
Do you think this could be linked to the update or could this just be a coincidence and there's an underlying hardware fault.
Let the new update run for a little bit...let it settle in
It might just be the spot u in and I doubt its the phone
Might be uodate but how long u been on the update?
Sent from my SAMSUNG-SGH-I717 using xda premium
Think the update came through on Tuesday.
Will give it a few more days to settle and see how it goes.
Thanks.
Still having an issue with this.
My internet worked all weekend then today started to fail on me again today.
The phone shows a HSPA connection but will not download any data.
I know it's not the network as my wife is on the same network and is having no issues.
Any help will be greatly appreciated.
Same problem
I am having the same problem here. I just bought SGS3 about 3 days ago and I started noticing data drop out yesterday. I wish someone could help me. I was hoping the problem to be solved by the time we get firmware update.
BTW, I am also having problem using usb tethering or wifi hotspot. After using usb tethering for about 10 minutes, it stops connecting although the phone still has data connection.
Is it hardware or software problem???
Thanks!!!
having the same issue after power saving goes on i lose h+ until god knows when

[Q] Wifi Issues

Just picked up this phone very happy with it. Only problem I have is it will not connect to any wifi hotspots. It will attempted to connect and quickly drop signal and disable it. Is this a software issue or a setting I am missing?

Im having a different wifi issue, it wont turn on period. I know it worked when i got it but i havent tried since s-off, hopefully unrelated. Maybe a kernel issue. do u have s-off?
I had to exchange my first max because the microphone wouldnt work during calls. It also worked the day i got it then stopped.
Everything is completely stock I haven't tampered with it yet.

No mobile internet after wifi disconnect

Hello everyone
A week ago I bought my Galaxy S9+. Sad to say that I've been having connection issues. When my wifi connection drops neither apps nor browser can connect to the internet even though the 4G logo is present at the top bar. To resolve this I need to do a reboot and then everything works normal.
Anyone have an idea what the problem might be?
Does this seem like a problem I could fix myself or should I return the phone (which I prefer not because of the hassle)...
Hi, have you found any solution to your problem? I have a similar one and it starts doing that after the last update in June, before it used to work fine.
