[Q] having connectivity issues with wi-fi - Samsung Galaxy S Relay 4G

hi...
ever since i got this phone i've been having problems connecting to internet via wi-fi, while at first i thought this might be due to faulty AP, replacing it didn't improve things, and although i get good signal (standing infront of the AP) and have an IP address, there's still no internet, (or have some but then it goes away).
could this be a faulty device?

[Q] Wifi signal high but no internet connection (Samsung Galaxy i5500)

I just upgraded my router to a wireless one. Firstly, it's connected via ethernet to a PC and it is happily getting internet access.
On my i5500 I get a strong wifi signal. Wifi Analyser shows the signal at max constantly. I can also connect with Gmote and it works just fine.
The problem is that I can't actually access the net at all from the phone.
So basically I know that my phone is talking to the router with no problem. It's just getting out onto the internet.
Does anyone know of a solution?
try logging into your router and change the broadcast channel to something else and test it again. it should be something like a/b/g mode... define a single channel and see if it works.
I had originally thought that was working. It did for the first few minute where I had connection but then it just dropped.
I have noticed that I have some very small bursts where I can connect.
Do you think that trying the different channels may be the solution?
I have the same problem. Have you found a solution?
Still no solution. I went through every channel and every encryption method.
So far I've found that having the channel set on 'Auto' and then disabling encryption seems to give me internet connection through WIFI for at least the initial period but it eventually drops. But that's also not always.
I've also Googled it to death and found nothing. If you do find the solution please post it here and I'll do the same.
Maybe we can help each other.
make sure you entered the right password of wlan.
use a pc to connect the router and in the wlan you'll find the password.
Ok, just to clarify. My phone connects to the Router via WLAN. In fact I can use Gmote to control my PC. So the WLAN connection is great.
The problem is accessing the internet when using that connection.
I had similar problems with a router last year. I resolved the issues by flashing DD-WRT firmware. The manufacturer's firmware was junk.
Sent from my ADR6300 using XDA App
I had that idea but they don't have firmware for my router yet. I have asked them if they intend to make one.
Any chance the firewall on your phone is blocking your browser from using the Wifi?
Sent from my DInc via XDA App
I have no firewall on my phone.
Ok I've tried some new stuff and they I've had the longest connectivity so far (which is about half an hour).
First I made sure my Wifi wasn't set to turn off when the screen goes to sleep. Second, according to a forum I read, Netgear recommends channel 7. If that channels doesn't work try 1,3,6,9,11,13.
I then disabled encryption.
Fortunately no one near me uses Wifi at all and I've got the kind of walls that stop the signal from getting outside.
Anyway. It's working so far but I'll monitor and report.
[edit] And I forgot. The router was checking for firmware but it wasn't actually finding so I downloaded it myself. Seems that also made a difference.
Ok. I can confirm after 2 and a half hours my internet connection is stable. I even left half way through and when I came back it connected perfectly.
So as a summary here's what I did:
1) Get latest firmware
2) Change channel to 7
3) Disable encryption
I will change encryption and see if it still works

[Q] Conflict with EnGenius EAP9550?

Hey all,
I have a Nexus S (GT-I9020) and an old Netgear WNDR3300 router which I put DD-WRT on.
If I connect directly to the router, I get an IP address and everything. I'm able to browse the Internet/market from the phone and my signal bars turn green, which means everything's syncing fine with Google's servers.
However, if I put an EnGenius EAP9550 between the phone and the router, (used to repeat/extend the signal) I'm not able to browse the Internet/market or get green signal bars from the phone. I do, however, get an IP address. I have a laptop (which I'm currently on) that is using the EAP9550 without issue, so I'm a bit perplexed if this is a Google/Samsung issue or an EnGenius issue.
Does anyone have any issues with the Nexus S and any signal repeaters?
Thanks all!

[Q] Wireless distance issues with Sharp IS03

I originally posted this in the IS03 sub-thread but received no replies.
Not root-related but since a little under a week ago, my IS03 has been having a real hard trouble with wifi when at home. If I move more than 4 meters or so away form the router, I cannot access anything.
When this happens, I'll disable/renable wifi (from 4-5 meters away or further) and one of two things will happen: 1. My network will not even show up or 2. My network will show up (with a 'good' or 'fair' wifi status) but when I try to connect, it will disconnect immediately.
What I noticed through the Wifi Analyzer app was that even when the Android wouldn't show my network on the network list, wifi analyzer still registered it about -70dbm.
I originally thought the router is to blame but both my wife's AU HTC Evo and my Amazon Kindle have no problems using wifi from the same distance.
I also thought that perhaps the cover I have for the phone may be collecting dust so I removed it to no avail.
Any ideas why the wifi in my phone is acting up?
Thanks.
UPDATE since original post: I moved my router (Linksys WRT160N V3) to a more central location and installed DD-WRT (TX Power power set to default 71) and the problem went away for about a week but now it has returned. Both my Kindle and my wife's Evo have no issues with accessing the internet through wifi from the other side of the apartment but the IS03 cannot.
If I try to connect to wifi and I am right next to the router, one of three things will happen: 1. It WILL connect but I cannot access the net. 2. The network will show up on the available network list but it won't automatically connect (will say the network is disabled. If I try to manually connect, it will immediately disconnect. 3. Network won't even show up.

WiFi Roaming between AP's

I've done some research on WiFi roaming between AP's with the same SSID and posted my findings on the Google Product Forums but I'm hitting brick wall.
Anyone who has any clues on how and why this doesn't work? Here is the link that contains all my finding:
https://productforums.google.com/d/topic/nexus/93GcQ8O75q8/discussion
Situation:
I'm standing next to my WiFi access point downstairs, I have full signal bars and perfect connection. I then move upstairs (2 stories up) and move next to the AP located upstairs.
Expected behaviour:
The phone should notice that the AP it is connected to has very weak signal, barely 1 bar left near -85/-90 db which is hardly usable. On the next background scan it should also find the second AP has much better signal, around -45db and decide to 'roam' to the other AP.
Actual behaviour:
The phone maintains a persistent connection with the AP downstairs for hours and does not 'roam' to the AP upstairs causing bad connection and battery drain.
Anyone any idea's? Can we maybe start a discussion about this issue and get some dev involved maybe who can shed some light on how this is supposed to work in Android?
I have the exact same problem. My 2 accesspoints are both Asus wireless router RT-AC68U. It's very frustrating. I know this is an old topic but maybe there is a solution available? Or is the problem solved with Lollipop?
You could test it and let us know, I no longer have 2 AP's mainly due to this issue.
Same happened to me and i found my fix on an app called Wifi Jumper. It might help you.

Doesn't matter the SSID, it will just scan for a better signal every interval you set it to in the settings.
Yeah apps like that will do the trick but this is a workaround for the actual issue. The apps are user space whilst wpa_supplicant should deal with this. It will drain more battery than a proper solution.
The solution is quite simple, wpa_supplicant can do this but android does not put the proper directive into the conf file. It will need a code change in the android framework.
I can confirm on the new android lollipop preview my phone jumps to the high WiFi signal in my house. I have Asus ac68u and a airport used a extender and my phone never gets stuck on one signal.
Is it in extender or AP mode? If in extender mode the device does not need to roam, only in AP mode with the same SSID the android needs to actually roam..
The airport is a ap. I just set it to bridge mode in the airport settings so it can pull ips from the main router. They're connected thru a DECA connection. DECA is like moca but using different frequencies on coax wires.
Sounds like the issue is fixed if it roams before fully loosing the signal.
If you have root you could check the wpa_supplicant.conf to see if they have now added a line for the bgscan module. This would complete the theory.
Out of interest, do you have "avoid poor connections" set in WiFi settings?
I do find mine does roam, but I'm not sure if it is down to losing signal completely or avoiding due to poor

Android Devices Unable To Maintain WiFi Connection

I have four handheld Android devices and, currently, 3 standalone WAPs plus Verizon's FIOS router.
.
None of the four devices can maintain a connection to any of the standalone WAPs or the router for more than a half-second or so: they solicit the PW, Authenticate, connect briefly, and then drop the connection.
.
I normally have only one WAP, but added the two just to make sure the problem was not in the WAP. Ditto Verizon's router, whose WiFi is normally turned off, but turned on now for troubleshooting.
.
For the life of me, I cannot think of any changes I have made in the week leading up to the onset of this problem.
.
One of the standalone WAPs is an Orbi Mesh system, but currently with no satellites - the satellites having started to act weird with onset of the problem and therefore having been turned off.
.
I also have two instances of AndroidTV running: one on a Sony Bravia TV and the other on an NVIDIA SHIELD box. And, weirdly, both of them are able to hold a WiFi connection - but UNABLE to hold a Ethernet cable connection. Same appearance as the handhelds over WiFi: connection gets dropped, only almost instantly so the screen just kind of vibrates with the connected.
.
If I turn off all standalone WAPs, leaving only the WAP in the Verizon router, the problem persists - with the Verizon router's WAP on channel three and, according to the WiFi Manager Android app, no competing signal sources on channel 3.
.
The problem persists even with the handhelds within 10 feet of the various WAPs.
This started about a week ago. Before that, no problems. And I don't *think* I have changed anything.
Right now, the only thing between me and hiring somebody to troubleshoot the problem is the weirdness of the problem - and the fear that their billing by the hour could cost me too much.
Can anybody point me in some direction?
