WLAN + Bluetooth = FAIL

Why is it that when I have WLAN switched on and try to speak using my BT handsfree I only hear interference???
Man it sucks!!

i do believe they operate at very similar frequencys however why that isnt a problem on other bluetooth and wifi enabled handsets i do not know.

I noticed this the other day too. Whilst connected to my router via WIFI I tried to bluetooth a file to another phone and my WIFI link dropped.
Surely they can both live and work together happily!?!

Strange - I don't have this problem. I regularly use wifi and BT together with never any problem.

Try to change the wlan channel in your wlan router. My router has 13 channels. I guess your router has also more channels. Set an another channel so will be more place between the bluetooth und wlan frequency.

wifi and BT
Well on my notebook (toshiba) when activating bluetooth first time with wifi on, I got information message, that as mentioned at the top, they operate on same frequencies, therefore, they can (but must not) interfere.

I will try that! Thanks for the tip.
EDIT: Tried several other channels and seem to have found a working one. Many thanks!

I´m happy to hear that my tip was the solution for your problem. Have a good time with your HD!

[Q] serious wifi issue!!!

After spending time searching the net for a solution i couldnt find anything as it seems my problem is unique. The issue is when i connect to my router through wifi every thing goes fine however when i go out of range or disconnect for a while and try to reconnect i get a message "Connecting..." then "Disconnected" and it never connects until I restart the router. The issue was worse where it connects for 1 time but the next time it does not detect the router, this was resolved by setting the wifi channel from auto to channel 6. But now i am stuck with this issue that has no solution. I have tried everything from static IPs to mac filtering, i also wanted to update the router (gigaset 504 agu) firmware but could find it. I am currently using x10 with firmware 026 -global. If anyone has a solution plz share it as this problem is really annoying

I have the same problem with my netgear router, it is very annoying...I think this a known issue with some android phones and certain routers.

Its seems no one has a solution, I guess we need to wait for 2.1 and see if the update resolves this issue

Well you could provide internet connection to your phone via your computer. What OS do you have and what kind of internet connection (wired/wireless) does your computer use?

Not that I've ever tried or used it seen as I don't have issues but perhaps this might miracally work..

I believe its worth a shot
P.s - Im pretty sure I've read up on a similar thread to this before..?

It's an android problem. I have this with my x10 and froyo nexus one. The only solution is to quick toggle wifi on/off in the power management widget. I've seen this happen on a Linksys wrt54g and wrt120n. Same with a D-Link dir655m and dgl-4300. If you are really unlucky like me. Having wifi and bluetooth on at the same time with this problem will cause your phone to either freeze or reboot on its own.

I get this with some routers, what works for me is. Data /3G, wifi off, 3g on, wifi on. I use switch pro to quickly configure the toggles.

just to be clear...do you mean you switch off data/mms then wifi off...then switch on data/mms and wifi.

thanx guys for the reply, but none of the mentioned solutions worked
I am seriously thinking of moving out of android because of this issue, its as if the phone doesn't have wifi?!?!

SGS1/SGS2 Wifi connects but no Internet data transfer

I was wondering if anyone else have the same issue, I tried on my galaxys ,galaxy s2 and even on my galaxy tab 10.1 wifi could connect but there is no data transfer, I have tried this on several routers in my office but the result is same, is this a bug on android or hardware problem?
I have tried static IP, change many things but no chance, I even tried on different kernels but...
** my friends with blackberry and Iphone can connect to the same router and have internet

most likely your office has blocked access through mobile devices

But as I say in the first post blackberry and iphone can connect

Yes I have the same prob, goes steady for ten mins, then just stops receiving a network connection, but my desire is fine. My honeycomb tablet does the same thing, but just turning wifi on and off fixes it. This appears to need a full reboot then works perfect again for a while. I've only had this phone two hours and have noticed it so surely others have.

I too faced the similar problem in the beginning dude...later some where in the forum one user stated to reduce the security level of modem or router from WPA/WPA2 to WEP/AES...then it works flawless...i don't know whether it is a problem with android or hardware...but most of the router or modem is secured with higher level of security which could not be accessed by our SGS2..i hope this would be fixed by software update..

Its is most likely router specific problem as its not a general problem and the majority have no problem with the highest security level .

It seems to be a problem with just some devices as indicated by this thread: http://forum.xda-developers.com/showthread.php?t=1194635. For a high end smartphone worth £500, temperamental wifi is a problem i shouldn't have to put up with. My router has no problem with any other devices so it's clearly a fault with the phone.

Never had an issue with wifi and wpa / wpa2 on multiple hot spots and home. Try a factor reset and flash . On kf3 xeu

http://tweakker.com/wizard/step1

That tweaker site is for GPRS/3g connection, this thread is about WIFI connection, so it won't help.
I have wifi problems as well. It connects just fine when i first configured the network but it won't work back from standby, although it still looks connected it won't transfer any data. Today i noticed an extra detail, it would seem that an app that was connected was still working but anything else i started fresh (like openinng the browser to access a page) wouldn't work.
I also noticed it loosing connection once after using it continuously for around 15 minutes.
Still haven't tried changing the security settings on the router, but, i previously had an ipad2 (for a short time, then sold it because it's just an expensive toy) and it would display the same behaviour.
Before that, i had a Nexus S with the same router and it always worked flawlessly! No settings were changed in the router.
I'm going to try lowering the security to wpa or wep and test it later.
If it works it might be a problem with the router but it's also a problem with the device (phone/ipad).
EDIT: one more thing, when i first got the SGS2 it had an older rom (vodafone KE7 i think) and it worked flawlessly until i updated it to a newer version the next day. I can't be to sure this was the culprit because i didn't use it that much the day before and it was a fresh install so maybe the issue didn't have time to show up.

one of my friends has a captivate sgs he also has the same problem, seems to be an android bug, or maybe samsung, another issue on this phone is about the bluetooth , it can not discover my headset bluetooth (sony DR-BT50) I have tried galaxy s , galaxy s2 and galaxy tab 10.1 but none of them can discover the headphone seems my galaxy life is messed up

Well i had similar issues with my vibrant and even on my nexus one....i think it is android bug....but if u r using cm7 or miui...u can easily get rid of it...by going to wifi settings>>>>advanced settings>>>regulatory domain>>>>change it to 14 channels....
but my sgs2 doesnt have this prob so far....i used those settings on nexus one and vibrant....and it worked....
Hope this helps..

Surely it would be backwards compatible.

It should be meaningless if bluetooth 3 not support BT2.x many devices still using BT2.X, anyhow my laptop is bt2 but I can connect to my sgs or sgs2

My Glalaxy s 2 has the same problem. It was fine till i was on KF7 but things changed with KG6 now.

My SGSII connects fine to every WiFi I've tried to join (open and ones that I know the password for). That is at least 3 different models of D-Link routers, a few Belkin and others that I can't recall.
I don't count a connection until I can actually view the internet and live stream the radio and I have been on it for more than an hour (I was proving to an ipad & ipad2 users that there was nothing wrong with a WiFi router and it was their toys that kept on dropping the connection).
I am was using the E7 and now F3 stock ROMs.
I did have a problem for about half a day. It would say connected to the WiFi but I couldn't get to the internet. I had to switch off the WiFi and connect via data connection and then try again with the WiFi - sometimes it would work sometimes it didn't. The only thing I installed prior to the problem was the Twitter app (from the market). Once I uninstalled that app and rebooted the phone everything was working fine. I can't say for definite that it was the cause of the problem.
To the OP: since you are connected to the work's WiFi, could the problem with not seeing the internet be due to the Work using a proxy server. That is what my work has.

Well I have a router that was supplied by imagine.ie, its a Motorola router and they with-hold the password to change settings on the router, have you heard the like????
Anyway trying that twitter suggestion, maybe the sync function was causing intermitttent wifi problems
Edit: Scrap them not giving out passwords http://www.imagine.ie/wimax_hub_setup.html

After a few hours survey I could connect my phone to the wifi, but Im not sure if this method works for you, anyhow I will explain here check it on your phone and report back
-Downaload the application "wifi static" from the market and install
-turn your wifi on and then run the application
-in the application choose add configuration,a window will popup saying have found a wifi connection will ask you to set for this connection or no just accept
-exit the application and turn off wifi
-turn on wifi and try to connect to internet,if you can connect then you are done if you can not go to below
-go to wifi static and choose the configuration which is already set and change the DNS I changed DNS1 to 8.8.8.8 and DNS2 8.8.4.4
-reboot (maybe not neccessary but recommended to do)
-turn on wifi and connect to internet and check if you still can not then...
-wait for me for further study

Nexus 4 wifi disconnecting

my nexus 4 connects to wifi for a few seconds and is really slow then. the wifi colour turns grey and is not working should i return it or is there a fix ?

wifi is controlled by kernel, are you on stock kernel or what are you using?
is it your router thats causing the problem? try it on another wifi network.

If you're talking about the Wifi going grey and not being connected to Google services but otherwise the internet works, this is a known issue that Google has acknowledged
http://code.google.com/p/android/issues/detail?id=40065
In the comment sections, a Google engineer has made a few posts and it's clear this affects numerous devices, which would mean wait on a fix, don't return it.

[Q] Nexus 4 Wi-Fi issues.

First - Hi all, long time reader but this is the first time I've needed to start a thread - so sorry about my first post being a problem/Q!
I've not had my Nexus 4 long, but have got some pretty annoying Wi-Fi issues. I've searched for answers but it seems that people have different Wi-Fi problems and I just wanted to see whether my issue was a common one and, if so, is there a fix on the horizon?
My issue is that I can connect to some routers but not to others (work, home, most open networks)... when I connect it simply says "saved, secured with WPA/WPA2" but wont then connect.
Phones running stock 4.2.1 with franco kernel r28 and the things I have tried are:
Resetting routers
Assigning static IP address
Wi-Fi direct from my Nexus 7
Cleared cache from recovery
changed the Wi-Fi band from 'Auto' to 2.4Ghz and 5Ghz
Flashed new kernel
Very frustrating and because of my signal the lack of Wi-Fi has made me go back to my old phone while I wait for a fix... which connects perfectly to the networks (S3 running CM 10.1)
Is this a 4.2.1 issue - as seems to be the consensus with other Wi-Fi issues or possibly a hardware issue?
Thanks for any info!

There's one fix you've not tried which might work for you (it didn't for me). You would have to be rooted though, which is going to system/etc/dhcpcd and changing the permission on dhcpcd-run-hooks to read and execute from "others". This help some people out but turns out for me that my router isn't compatible with my phone. (DSL-2780).

I've noticed that some of the mobile devices(eg iPhone 3gs, SGS2) are quite sensitive to wireless channel which your router/ap broadcast on.
Try manually switch to channel 6 or 8 that solved my issue - I don't believe in incompatible routers usually problems are related to config.
It is more complicated with an access to the public WiFi as you can not modify the setup.

Just to update.
I've now tried this and still can't connect to the affected Wi-Fi networks, probably going to have to wait for 4.2.2 to see if that fixes it...

I too have wifi issues with my N4. We have several phones at home - an HTC Aria and believe it or not the SGS1, SGS2 and SGS3!
All of them connect with no problems. My brand new N4 will see the router but refuses to connect until I toggle wifi on/of serveral times in succession, sometimes 6-8 times!
I have avoid poor wifi disabled but it does not help
I really hope El Goog fixes this asap as it is very frustrating.

I've had this issue forever. Android phones hate low or overcrowded signal. Though my nexus 7 always works fine. Makes me think it is the lack of WiFi antenna strength
