[Q] wifi range

i have trouble to connect to wifi. have problem connecting to wifi where other phones, NB dont its just showing low signal... can someone hlp?? thx in advance

How many "bars" do you get when sitting right next to (3 feet/1 meter) a wireless router?

its full but when i go further like next room it drops to one bar and disconnects. thats my wifi at home and when i want to connect to someones wifi i have one bar where he has full ... would it work if i go to winodows mobile 7 or i checked forums and there is a way to enable 802,11n and it should fix the range of the wifi

looks like ur having the same problem as he is. check this thread and read thru post #5 to last.
http://forum.xda-developers.com/showthread.php?t=1150312

+ check if you can get any BLUETOOTH connection (pairing)
if it fails...definately a loose cable issue as i mentioned in that thread.

BT is working perfect even in range where wifi makes problems so i dont think the cable is the problem. if im in one meter distance wifi get full bars but when i check the signal longer it drops to half and back to full. so when the signal is half or less it drops below range and the connection failes. can you tell me whats the max distance of the wifi in HTC HD2??? have the phone in warranty so will try that but dont think they accept this so trying to solve it my self...

depends on the router

is it possible to buy better wifi chip to my phone?
my router is D-link dsl 2641R

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.
Accidentally sent from my Samsung Galaxy Note 2

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:

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).

Selective Wi-fi

Hello everyone,
I checked the forums and I haven't seen anything like this, but I'm hope my situation isn't unique.
So I got the Nexus 4 and I love it. I have it linked to my wi-fi at home and the campus wi-fi. Every time I got to the college campus it links just fine. However, when I get to the home wi-fi, it sometimes takes a while for the phone to connect to the wi-fi, or say that the wi-fi is out of range.... even when standing next to the router.
I've tried rebooting the router, rebooting the phone. When it connects it's awesome. Sometimes I have to turn off the wi-fi on the N4 then back on again for it to connect.
Does anyone know what this may be? Anything would be great help.
P.S. - everything else works on my wi-fi just fine. A couple Rokus, a notebook, and etc.
Thank you

Nexus 4 has several flaky wifi issues. When I first got mine I could not get it to connect to my home router at all. Then it just started and has been working fine ever since. You may try changing your frequency settings on the router or using a different security protocol. In my case it seems once it got connected the situation was resolved. Good luck!

I tried changing the frequency, seeing that my neighbor was on the band as me. I'm not sure if that did the trick, but now my N4 seems to be picking up the signal a little more quickly.
Thank you for your suggestion.

Same issue here. Sometimes I'm connected to campus wifi, I drive all the way home and look at my phone, it's still trying to connect to campus wifi. I have to turn wifi off then back on for it to disconnect and auto connect to my home wifi.

"Internet connection too slow" notification

Hey kids.
I came from the S3 the beginning of November. One of the "new" annoyances I've come across is a notification that the wifi connection Internet speed is too slow. Which is bull. The only way to reconnect after that is to reboot. Sometimes enabling airplane mode does it as well. So my question is twofold. Has anyone else come across this? Has anyone figured out how to turn this stupid setting off?
Thanks in advance.
♢NoteIII♢

I haven't encountered any of these problems. My Wi-Fi signal it's weak at times, but when I have a good connection internet speed is fast
If I helped hit thanks!!

im not saying this will fix your problem, but i was getting these messages as well. I switched my wifi power saving off via service menu. I also changed my router band from 2.4ghz to 5ghz 40 bandwidth and i havnt seen the message in about 2 weeks.

Thanks. Actually did the power save to off this morning. Happened again this afternoon. As far as switch to 5ghz, I've found that my wifi signal's reach gets cut by about 20-30 feet on that band. Which means I lose reception in part of my basement. I can move my router more centrally in the house, but overall speed suffers (goes from a solid 8-10mbps connection to about 1.5 mbps) cuz the wiring to that receptical is sketchy.
I can get that stupid message in the same room as the router.

yeah 5ghz band will cut your signal strength in half probably. Maybe buy a dual band wireless access point? Its wierd that your speed goes down on 5ghz. Mine practically doubled on my note 3. My house connection is 100mbps / 5mps. On 2.4ghz i can only get up to 30 mbps, when i enabled 5ghz wifi, i shot up to ~110mbps down.

that's ridiculous... buy another router or access point? Its the phone, not the internet, when you get the notification when you're right next to the router. The Note 3 is the only device on my house giving me Wi-Fi issues. Sorry I don't mean to sound like an arse, but it seems silly to buy a phone and have to replace your router, when everything else works just fine with the WiFi signal.

Just to clear up, speed goes down when I connect to the other phone plug. So my router (brand new, furnished by internet provider) is on one side of my house. And this happened before moving in mid Nov as well. Before was cable Internet, now dsl. It's the best thing I can get @ current location.
I'm not sure if it will actually solve anything, but I received the latest update ota. Tomorrow gonna download latest firmware and flash via odin avter wiping everything with safestrap.

Kancerstick pretty much had it right. Rather than switching the band from direct 2.4 to 5.0 though, go into your router settings and look for a setting that says "channel".
What channel are you running on? There are 1-11 channels, try different ones or the idea is to find the one that matches the channel of the phone/client device

The one solution that did work for me was to go into the WIFI Settings -> Advanced option under the menu key -> Uncheck the "Auto network switch" option. I haven't had any further issues with that message so far.

tried everything...
I think I have tried everything on this issue. I got my note 3 a few days ago and it will not keep a stable network connection. tried:
1. uncheck the auto switch
2. turn off mobile networks
3. turn off wifi when sleeping
4 changed my router to static ip and not DCHP
5. forget and reconnect to network
6. reset router
I don't thing I can change my router settings anymore or I will have issues with other equipment
I am sitting right next to my router and everything else works fine but my note 3 will not keep a connection. I keep running speed test and half the time it works and half the time I get a no connection error.
Any other thoughts? Should I try another unit?

Wifi disconnects and reconnects constantly

Hi,
just had the phone for an hour and almost right away after first setup the wifi radio disconnects/turns off and re-connects/turns on automatically every 20 seconds or so. No matter wich network I try.
Working fine with my S7 Edge laying here beside me, never had problems. I have three different networks around me I can try out.
Anyone had the same problem? I can find som info about this exact issue for the S7 Edge for some, but no solution from that works on the S8..
N

this is an old problem S7 had
you need to toogle in settings > connectivity > wifi > advance > smart network swithc OFF
i think this was - but dont remember well since it was a while ago - but basically you need to turn off the option of phone switching between phone and wifi data

Having the exact same problem with my Ubiquity wifi network (ie, not some janky cable company router) with my just-booted up S8. Smart switch was off by default, and after switching it 'on' and back 'off', no change.
This was the first thread I found on the topic, will update with any solutions.

Try downloading wifi analysis app and see what it's picking up. Maybe you could try changing your wifi channel if it looks low?

No this has nothing to do with the routers or access points. I am 3 meters from the AP, its at 100% signal rate etcetera..
This has to do with Samsung and the software.

As I wrote I've tried all that I'm afraid. All the things that was recommended for the trouble on the s7.

have u tried going to a free wifi spot (starbucks, mcdonalds) see if the issue persists - maybe is your router refusing connection

As I wrote I have three different wifi to test with but yes makes no difference. This is a well known but not solved problem with Samsung phones.. three different makes of manufacturers, different settings with a/b/g/n and all show the same problems.
I also installed the small new update today for the firmware. Still same problem.
I'm guessing I'm about to get a replacement phone. I'll try that on Monday.

I'm not seeing the same problems with public wifi as I am with my Ubiquity Unify AC AP Pro access points at home - definitely weird.
When it is connected, I'm getting my usual 100mbps speeds, but it continues to drop regularly (not the every 10secs it did when I first powered it on, but every minute or so).
One thing that was mentioned was changing channel bandwidth from '40' to '20'... I don't see anywhere to do that on the S8?

Doesn't that mean on your router?
By changing the broadcast bandwidth from 40 to 20 you will increase the signal produced (same power is covering less channels)

I had this happen on a UniFi UAP-AC-Pro network with my S8 as well. I turned off Nearby Device Scanning on the S8 under Settings-> Connections -> More Connection Settings and that seemed to fix it. Strangely, I did not have the issue on my home network which has a single UAP-AC-LR access point with an otherwise similar configuration. Not sure if this setting change was really a fix, or if I just temporarily got lucky.
If turning off Nearby Device Scanning doesn't work for anyone, it might be worth playing with other settings within your network such as Band Steering. Some of these require turning on advanced features within the UniFi controller. Also I would be curious to hear whether those who have issues are on networks with a single access point, or larger installs with multiple access points.

Very recently got the Samsung S8 and I'm having some wierd WiFi issues. When connecting to the network everything is fine i get almost maximum download/upload speeds(500/500) from my UniFi AP-AC-PRO. But after being connected for awhile 30-60mins the speed drops to around 30mbit downstream and upload around 200mbit. If i disconnect from the Wi-Fi and instantly reconnect i get full speed again. I've tried switching settings in the ap, went from everything on auto settings to static channel/transmit power and been trying vht40/80 but makes no difference. If i have smart network switching on i get disconnected and put on LTE instead. All my other devices have blazing WiFi speeds as usual. I'm gonna try turning of nearby device scanning and see if that helps.
I started a thread in the ubiquiti UniFi forum as well but i cant link that here(not enough posts on this xda account)

I'm having the exact same problem as you. Wifi connects at full speed at first, then after a while speed drops. Has gone down to 1Mbps numerous times. Disconnecting then reconnecting fixes it for a while then it starts all over again. I'm connected to a TP-Link AC1900 running dd-wrt. May try going back to stock firmware on the router to see if that helps.

So has anyone come up with a permanent solution to this? I'm in the same boat with my ac-ap-pro and s8+. Disconnects every 20 seconds or so.
