Dropping wifi with multiple APs

Hopefully this is another known bug in 4.2 but on my N10 the wifi frequently drops from my router if I connect to a SSID with multiple access points.
Basically I have 3 x 2.4Ghz and 1 x 5Ghz access points around my house. All APs are on the same subnet, have the same network name (SSID) and same security settings. All my other devices (laptops, ipad, android gingerbread, android ICS, etc) all play nice with this and move seamlessly from one AP to the other when moving around the house. My new Nexus 10, on the other hand, does not. Even sitting in one room, right next to one of the APs it will randomly drop and reconnect to the network. Wifi analyser shows that the signal to all APs is fine. I'm guessing its flicking between APs.
As a workaround I changed the SSID on one of the APs to be unique and told it to connect to that - its been fine since but obviously this isnt the ideal solution.
Another 4.2 bug?

I've never had any luck with Android and multiple WAPs with the same SSID. At least for handoffs so I was forced to use mutliple SSIDs. Wish Google would get this taken care of! One of my only real complaints with Android...

I just found and installed this...

Not sure if it works yet.
Theres also an open bug:

I'll report back...

Note 2 not automatically switching to stronger WIFI signal?

Ok this may be kind of a long post but I'll first address what I think is the issue.
My note 2 doesn't appear to be automatically switching to stronger available wifi signals unless I manually toggle the wifi off then back on again. It will then connect to the stronger signal.
The reason why this has become an issue is because I bought a Diamond WR300n wifi range extender. I'm using it as a reapter. I want to have better wifi signal in my garage where I spend a lot of time. My current wifi signal drops off pretty much near the garage when using my phone. My laptop still gets decent wifi reception when I'm in the garage though.
I went through the fairly basic setup for the extender and got it working. I confirmed this by plugging in the ethernet port from the extender directly to my laptop and its receiving a signal just fine, browsing the internet etc.
So i put this extender in my garage, it connected normally and I confirmed it was working using my laptop again. Everything appeared to be working fine. The extender has the same SSID as my main wireless router (uverse 78wireblahblah).
The issue is when I'm inside my house I'm connected to the main wireless router because this is obviously the strongest signal. When I walk out of my house the signal diminishes as I approach my garage. I can walk into my garage and my wifi signal is pretty much gone even though there is this repeater putting out a working wifi signal with the same SSID as my main router.
Weird right, one would think it would automatically switch and connect to the repeater in the garage, but it doesn't.
Now if I manually turn off wifi and turn it back on while in the garage, bam, very strong signal and I'm connected. There really is two issues though, 1. my note 2 is not automatically switching over to the stronger signal (both the repeater and main wireless router have the same SSID) in the garage and 2. sometimes it connects to that stronger signal in the garage from the repeater (only after i manually toggle wifi off and on) but the internet doesn't work. I'm actually connected to my network because I can access my "Yamaha receiver app" that lets me turn up volume etc on my receiver but I don't have internet access etc. This is usually the case but after awhile it just seems to start working and I have full internet access.
I know this is only semi phone related but I figured since alot of guys on here are very savvy with this tech stuff, maybe someone could help.
Again
1. why won't my note 2 automatically switch over to that stronger wifi signal which should be the same in the garage.
2. why does it sometimes only connect to the network but doesn't allow outside internet access.
Should I try the "wifi jumper" app that supposedly auto switches to best wifi signal (i thought our phones do this anyways)?
Not sure if this is the right place to post this so please move if need be =)
Thoughts?

Stay on what Samsung preset.
Basically I owned a nexus s, it does have automatically jump to higher signal router or access point in android 4.1+.
So basically the WiFi just jumping from my router to access point and from access point to router and I ended up getting no WiFi signal. I have to switch off my access point (extender) to get my WiFi working again...
And note 2 won't give me this problem.

If you'd ask me, just buy wifi jumper, you won't regret it!
It works perfectly fine with my 4 routers, all with different SSID. It's nice to have the best signal available wherever you are in the house. Wifi jumper gives me the best results I have had since trying a few different apps like it. The owner just finished rewriting the code for connecting to different routers with same SSID, so it should be the perfect solution in your situation!
And no, I'm not affiliated with it in any way, just a happy user :thumbup:

wifi jumper is a good idea

Yeah, Wifi Jumper is probably the way to go. In an ideal world, the WiFi stack would roam properly in all cases, but sometimes you're just not quite far enough for it to roam. This is even an issue with the PC also, but most manufacturers allow you to configure the roaming behavior of the driver to your tastes (max range or max speed).

will android switch to a better wifi if available?

Heyho, i currently have access to my wifi as well as to my neighbors network as my wifi gets weak while i am in the garden. I feel like android isnt awitching to my neighbors wifi automatically. Only when my wifi is completely gone, android will look for a new one.
I thought about making a task with tasker which looks for another wifi as soon as the current wifi strength goes below 25%.
Or is/should android do that aleady on its own?
Thanks

In wifi -> Advanced settings there's an option to avoid poor connection. I have no idea what it actually does, but give it a try.

I did the test with my router, which supports 2 frequencies.
Assuming both networks are saved in the phone, it connect automatically to the one with better signal or look for an alternative if signal is lost.

Thats what I mean, it will connect to the other WiFi if the connection is lost. But if the connection is crippled (bad) enough to not handle a music stream, but still "availabe" it will not switch to the other WiFi eventhough that other WiFi has 100% signal strength ?
I activated the "use wlan only if good strength available".. lets see how this works

I have multiple APs in my house and the only way I've ever got it to switch is by toggling wifi off and on (or loosing the first signal completely). This is an Android issue IINM, my GS2 and my N4 both have this issue.

I tried the "do not use weak WiFi".. didnt work.

It has never worked for me either. Didn't work on my GSM GNex or with the N4.

I think it's how most WiFi clients work, otherwise if you were in the middle of 2 equal signals, it would spend more time disconnecting and reconnecting creating a DOS attack on the 2 AP's and leaving you with no data.
As for 2 home wireless routers, use the same SSID and authentication settings for both, and put one on channel 1 and the other on channel 11.
Make one a AP only (no router, no firewall, no dhcp server) and connect it to a client wired port on the first one. You can roam between them like people in large offices do.

or I try to make a tasker profile
if wifi strenght below 20% and another wifi is available with more than 30%, connect to that one.. then wait 5 minutes ?

Wifi not reconnecting

What happened:
I am using a new Nexus 4 in various buildings on a campus (specifically, the University of Washington). For simplicity, let's assume that there are just two buildings, Building A and Building B.
There is a strong WiFi signal within both buildings, and I can connect to the WiFi network in either one. When I walk between buildings, the signal drops outside, and the phone switches to 3G networking (as expected).
Once I'm inside the other building, however, the WiFi does not always automatically reconnect. Instead, the phone will often remain on 3G mode, despite being in the presence of a strong WiFi signal.
If I restart the phone, the phone will then reconnect to the WiFi signal. Unless I do this, however, the phone will remain in 3G mode indefinitely. This drains the battery and results in high data usage with my phone plan.
Steps to reproduce the problem:
1. Connect to campus-wide WiFi.
2. Walk outside. WiFi connection will drop, and phone will switch to 3G.
3. Walk inside another building. Phone will remain in 3G mode, rather than switching back to WiFi, despite being in the presence of a strong WiFi signal.
4. Restart the phone. After rebooting, the phone will now connect to the WiFi network.
What you think the correct behavior should be:
The phone should automatically switch back to WiFi when in the presence of a suitable WiFi signal. A manual restart or manual reconnecting to the network should not be necessary.

Did this issue occur before you were on PA rom 3.5?
If it didn't then I think it could be the rom if it's not then it's the school's wifi. It happens to me when I'm on campus too and I found out it the school's WiFi network was getting hammered and the signal was disrupted. No clue how that any of that happened.

Hi, I have the same problem. Did anyone manage to solve it? I have my Nexus 4 since yestereday and it's not reconnecting to my home wifi. Previous phone HTC Incredible S didn't have this issue and since that phone my wifi settings wasn't changed. I have AirLink AP, no name router and wifi is encoded with WPA. But i don't have to restart the phone to reconnect. It's enough to turn wifi on the phone off and on in settings. But it's really annoying. Thanks for hints.
And please excuse wrong expressions, I'm from Czech republic
Edit: I have stock rom, JB 4.2.2

Wifi issues on Airport Extreme 750AC

The only issue I've had with the phone since receiving it on Friday is network issues using wifi over and Airport Extreme 750AC, that we have at work.
I upgraded to the 6p from a 2014 Moto X, which had no issues at all with the wifi at work. Also no one else at the office has complained about this kind of issue either, with a mixture of Android and iOS devices.
The phone connects to the wifi quickly, with very strong signal strength. But something is interrupting the connection after 10-15seconds, causing full loss of transmission. After another 10-15 seconds of no connectivity, it will come back strong for another 10-15 seconds. At home, wifi signal strength and speed has never been better, using a Cisco e4200.
Has anyone else experienced this with their 6P?
EDIT - This still occurs if I tell Android to connect to 2.4ghz, or 5ghz only, and not automatic. Both 2.4 and 5ghz networks use the same SSID.
EDIT2 - Issue resolved. Was not due to anything on the device, but an issue with the network DHCP instead.

I've brought a Nexus 7 to work running Android 6.0 as well, and it has no issues with the wifi. Posting just in case someone else runs into the same issue.
