[Q] Do you have speed problems with Wifi? (N-band)
I have wifi N router and set to N only. I have two laptop both wifi N capable. When I transfer file usung file sharing betwen two laptop I m getting speed abt 3Mb/s but when i transfer file between laptop and SGS I only get speed of 300 Kb/s. SGS support wifi N standerd then why it so. Well I use ES file explorer to access file in my laptop over Wi- Fi.

It's a mobile device, they have lower throughput and probably only 1 antenna (most 802.11n devices have 3). There are a lot of factors, but basically, all that's important is that it supports the 802.11n protocol. Optimisation may lead to faster speed boosts over time though.
Network traffic might also be set to a low priority to help ensure the phone runs reliably for other tasks, but I have no idea why exactly it's slower exactly.
I get 1.5mbs from my nas and wireless n network
Sent from my GT-I9000 using XDA App
i get 19.5mb downlaoding speed
and 4.3mb uplaoding speed
on my wi-fi
my connection 500/500mb
I m talking abt internet speed. I m asking abt file transfer speed betn my SGS and laptop
Sent from my GT-I9000 using XDA App
87 Mbps according to mine
i'll grab a screen shot when i get back home
87 seems too much I only get 25 while copy file on hard drive it self
Sent from my GT-I9000 using XDA App
that's actually low for me, but is better than nothing
my PC down in the cine room gets around 218+ Mbps
I get about 80Mbps laptop <-> network (802.11n 5Ghz), and about 5Mbps SGS <-> network (802.11n 2.4Ghz). Not horrible, but certainly not wonderful. I wish it had a 5Ghz radio too, so I could turn off my 2.4Ghz stuff :-/
[Q] Do you have problems with Wifi? (N-band)
Since my phone is on it's way to the repaircenter I would like to ask you all this Question.
I have problems with my wifi connection. The strange thing is, is that my router is brandnew! b+g+N!!!
The weird part is that it has only problems with the N-band
SO I hooked up another wireless router only with the b+g band and BAM it works.
But that's just messed up to have 2 wireless routers one for laptops and one just for my mobile phone...
So can u try the same thing and give me your comments about this issue?
there was already a topic about this
however one topic we did not touch base on, on the other topic was about the B+G bands
if you read the documentations you'll noticed that for N to work at full speed, it must only listen to N no B no G
when you use Mix mode, N doesn't work well
to use N, you need 2 bands, B + G only needs 1 band
if you enable all 3 B+G+N you only get 1 band for all, so making the N useless
the trick is to update all your old hardware that still runs G or B to N
then you can use pure N, and gain full speed
the SGS phone can run up to 87 Mbps on N
meanwhile computers can go up to 280+ Mbps

Can't connect to home WPA2 wifi
Hello!
The problem is that I've been trying to connect to my home wifi like 100 times or more, but I'm still unable to get it working... The wifi it's WPA2 and it has a long sentence password...
Any ideas? Thank you!

Maybe you need to shorten your password to try.
[Q] manual wifi fix app?
Hey, like many Android users I'm often having problems with Wifi not connecting to APs. While that can be fixed by restarting Android that takes a lot of time and is more than annoying. There are some apps to solve this issue, they "fix" wifi whenever the screen is turned on (e.g. http://www.appbrain.com/app/wifi-fixer/org.wahtod.wififixer http://www.appbrain.com/app/blade-wifi-fix/com.bladewififix).
That however I don't like either as due to the fixing taking place always wifi connection becoming established takes quite a lot of time. So my question: Is there an app that fixes the wifi connection but does so only manually, e.g. by clicking a widget button?
[Q] Can't connect to Wifi?
I select my Wifi network, I enter in the password, it says connecting, authenticating, connected, remembered, then it says disconnecting, searching, authenticating, and it repeats. The H at the top never disappears, no Wifi icon ever appears, what is the issue exactly?
And yes, I am connecting to a Wireless-G signal.
Don't worry I can't connect to your home network either so it's not a problem with your phone
I suggest you delete the password from the router and try and connect .
If you connect setup again with the password .

I had the same problem and i manage to fixit with "WIFI STATIC". It's free on Market. Access your router config and add your Galaxy Mac adress, then fill the parameters in WiFi Static. It Works! Never had problems again! Oh, i think you have to put your's computer(s) mac adress too in the router.
is there really no such app? :-(
my ms2 connect to my home wifi
after i enter the password, then it said disconnected, and my home wifi are also disconnected, even i factory reset my ms2, the problem still hvnt solve, wt can i do now?
did you try change the authentication type, mine works fine with my home network with wpa/psk2, some time ms2 connect, then tell disconnect, and if i try again he jump to acquiring ip address
where can i change the authentication type?
it works fine in hk
but after i bk aus, it not work anymore
What's the model of the router?
rounter midel
:
dynalink
RTA1025W
me too.
y?
After working for some time, it will disconnect, to switch to flight mode, then switch back. However, after a period of time disconnected
i think my problem is more serious
cuz is the whole wifi disconnect, even the computer :S
make me suffer alot
try this: change the wifi mode from "B/G/N mixed" to "B/G mixed"
it is already 802.11 b/g mix mode
Hi,
In my MS2 this problem also occurs when I'm connected to a router with
"B/G/N" suport, like the TP-Link TL-WR1043N / TL-WR1043ND.
I have a old d-link with support only for B/G mode, and the phone works perfectly on G mode (54mbps).
This behavior can be a MS2 of the failure of the wifi networks with N standard ?
regards,
Daniel

That's right, Motorola defective drivers for wifi don't stand being connected on N connections...
Sent from my Milestone 2 XDA App
My WiFi on the Atrix crashed all my 3 routers (ActionTec/Dlink/Linksys), sometimes after a few minutes, sometimes after several hours.
The routers needed restart after that. Also wired connections were affected.
I tried messing with static IPs and sleep mode, nothing worked!
Now I upgraded my Dlink DIR 655 from 1.11 to 1.33 (supposedly the best).
Things changed
Now my Atrix takes only itself down, the Dlink keeps working for other wireless and wired devices.
The Atrix says its connected and I get the icon with full bars, however no data is transferred. The market and other apps say network error.
I can switch connection over to my other WIfi network and all is good again.
Has anyone seen this behaviour?
Also is there an app that shows me the link mode G or N and the current link speed? I cant seem to find a good app. I would also like to see if I can lock the Atrix to G or N only. Is there such a toggle switch?
Thanks.
Update: Switched connection from Dlink to Linksys and it worked for about 30 minutes then the linkksys crashed (could not reconnect got no IP). Switched back to the Dlink, got connected, good signal but no data. Even after a phone reboot. So I think it might be still on the DLink side although I have Netflix (PS3 wireless) and another PC connecting fine. This and the VOIP mic problems (Skype etc...) bug me the most about the phone.
ive been having this same problem since i got my phone and im still having problems. its pissing me off. cant even use my netflix through the Wii to watch on the big screen

centurylink is my isp. i dont know if its my router that is just crappy or my cell phone is interrupting it while the wifi is on and im trying to browse causing the routers wifi to cut everything off thats on wifi
I don't know if the good post but I've got WIFI problem on my tablet Polaroid MID 9748 Android 4.2.2 kernel 3.0.36, CPU RK3188
Tell me if I've been moderated.
For example, when I switch from an application to the other as my browser to google play. Then I've to switch my tablet in plane mode in and out for refreshing the WIFI connection for connecting back. The wifi bars are showing me that I'm connecting all the time, but my browser can download any page.
I don't know where this problem is coming from because I'dont have any problem for watching streaming also the wifi card should work fine.
Could be MTU problem? How to check?
Thank for advise
Have you tried to reboot your access point in first place? MTU should be 1500 as default.
Does is happen with other devices ie. laptop?
Hi Ollve,
My laptop has never been disconnected from WiFi. Only my tablet is. I setted a fix IP address for my tablet in my access point. I installed WiFi fixed. This app found when I m disconnected but it didn't restore the connection well. So I've to do it manually.
In hoping may help
Thank for your support.
Just got the S8 and I have 3 Wi-Fi access points at home to cover the whole house. My S8 has been registered with the passwords for all of the APs but it continually rejects the connections with an exclamation mark after the WiFi icon having connected and then shown a message that the Internet connection may not be available. The Internet connection is available as other devices are connected and using it perfectly. If I switch the Wi-Fi on and off and reboot the S8 the issue corrects itself but I should not have to go through that nonsense every time I come home and want to use my Wi-Fi. I have explored the advanced options on the connection settings and they appear to be quite limited (DHCP Etc). Is there some way to solve this issue? I have no problem with other android devices connecting to the same hotspots. Any ideas that might lead to a solution would be appreciated.

I had this problem when i first got my s8 from vodafone but when i got this latest update it's been good no issues with internet anymore.
I have this problem as well with my S8 from Verizon. Worked flawlessly for a week and them today I get this error. Very frustrating. I know the SMG955U from Verizon is already unlocked but is there any way to put the International ROM on the phone seeing that the Verizon and the International are the same?
I've tried all the resets etc and the WiFi connects but I get the 'Internet connection may not be available' message.
Update 27/04/2017
Thanks for the reply. My S8 developed some interesting issues including the switching on of 'do not disturb' mode intermittently and along with the Wi-Fi issue the mobile data was failing in areas where a full 4G signal was present. Rebooting, resetting etc did not resolve the issue and I returned the phone to CPW for advice. The staff at the Glasgow store wasted no time and exchanged it on the spot after some negotiation with their technical service centre. Full marks to CPW for the prompt service and I can report that all of the previous issues have now been resolved with the replacement handset. I thought it worthwhile to post this information so that others who experience similar issues may be able to get a similar resolution.
Poor WIFI performance
I also have issues with the wifi of the phone, /i will get the terminal replace some time today or next week.
1. WIFI keeps disconnecting, actually it's flapping connct&disconnect for 5-10 min until it finally connects, on this matter I have seen on the acces point that it tried to allocate an ip from an unknown without asking DHCP server for an IP renew it actually tries to alocate itself the last known ip, and clearly disconnects because of lack of internet access, this happens normally as power saving mode is on, disabeling power saving and assigning a static ip on the phone seems to resolve the issue.
2. poor wifi signal... no fix for this thus far
- i have 580Mbps speed connection on my S5 and only 120-240Mbps on my S8, steaming not working and connection in general very bad, time ots and stuf, although I position myself at 10cm away from the wifi router antenas i only get 540Mbps signal, although I have an AC1750 router , s5 gets 840 in the same spot... I think the modem(that is part of the Exynos chipset) does not work wekll with Atheros based AP´s , I have an Archer C7 with 2.4ghz QCA9558 chipset capable of 450 Mbps theoretical speed, but only uses 2 antenas as s8 only has 2 from my knowledge and reaches a max of 140Mbps(should of connected at 300Mbps at 10cm in theory ) with the s8 and QCA9880-BR4A on the 5ghz side of things with a theoretical speed of 1300Mbps should work at 866 with the S8 because of the 2 antenas of the S8.
phone changed 90% of problems fixed
Hello, just got my phone replaced, tha new unit has way better wifi signal considering I hace atheros router and the phone has broadcom 43xx chipset... worth considerign changing to a broadcom router...
Hi,
I have found a solution to this problem.
1. GO to wifi settings
2. Forget the wifi network
3. CONNECT AGAIN BUT BEFORE CONNECTING GO TO ADVANCED OPTIONS AND CHOOSE STATIC INSTEAD OF AUtOMATIC. Enter in the ip address etc and connect.( It requires to be entered manually) Problem will be solved.

I had just the same problem with s8 plus and s7 edge(after updating to android 7.0), it kept saying "internet may not be available", I changed the DNS to 8.8.8.8 and tue problem solved. Go to SETTINGS》WIFI》SSID》MANGE NETWORK》change the IP SETTINGS to STATIC》then change the DNS1 to 8.8.8.8 hit save and you are good to go.
Sorry if there are any mistakes. I am new to XDA and not good in english.

I have same problem and it is very annoying. I got 2 S8 plus and both have the problem.
There are 3 WIFI Router that covers my house. I have problems saying internet might not be available every time I connect. This is very annoying. Other Phones in the house like Iphone do not have the problem.
What I noticed is that the IP range of my router is:
192.168.1.1
But my S8 says he is connected but the IP is
192.168.0.100
Anyone have same problem?
Thanks!

I found a quick work around on how to fix this temporarily until Samsung issues a patch.
just turn off 5ghz SSID broadcasting and you should be ok for now.
here is a quick how to video i made on just in case.
https://youtu.be/Nu5FjDPLn-M
I'm having a very similar problem with my home WiFi and my Verizon S8+ I bought from Samsung's website. I've tried switching from DHCP to static and entering all my info. No luck. I've also switched my dns1 to 8.8.8.8 and dns2 to 8.8.4.4, and my WiFi router is set to 2.4ghz only. No success in resolving the issue. Currently my phone will show the "internet may not be available" with the added exclaimation point for a few minutes when first connected, then the exclaimation goes away and I'll have regular full speed internet for around 25-45 seconds before it goes back to a non-internet state. Any suggestions?
Try changing in your router the security setting. If your using WPA2 AES/TKIP, change to just WPA2 TKIP and see if this works for you...
I was having the same exact issue for months. I changed to TKIP only and have been rock solid ever since. No more ! at all... I'm gonna switch to just AES today and see how that works.
Changed to WPA2-AES and within the hour had ! back and no internet. Went back to TKIP and rock solid again. Looks like a possible bug with AES to me. Sticking with wpa2-tkip setting for now.
I'm having this same exact issue.
Anyone who knows what to look for to fix this, what info or files do you need from me? I'm at the end of my tether with this ****
I am having the exact same issue on my galaxy tab s2, even on the replacement. Due to the being such an intermittent problem, it wouldn't do it when Samsung support checked it out...
This happens on both 2.4 ghz and 5 ghz frequency for me. I've tried downloading a wifi fixer, I've reset network settings, and turned off nearby device scanning. I've also tried doing what a forum suggested by changing the ip settings from dhcp to static but it wouldn't connect to wifi at all. Not sure what else to try...
I read that it may be due to nougat 7.0 software. I was suggested by Samsung to first put the tablet on safe mode (this disables third party apps, and would reveil if an app was causing the problem) but the problem still persists. Also did a hard reset on the first tablet I had but it still done the same problem...
I always thought that this was a is problem in 7.0, and was addressed in 7.1. Hopefully, when the next major update comes out, this issue will be resolved.
Oh come on Samsung!
It's been 4 months since the first post and still no solution.
And it's a basic wifi connection!
Internet may not be available! = Samsung may not be available
Heya all. First post I guess
Edit: Gah it was the second. I have to controll myself better and not spam.
So I had the same problem and tried more or less all.
My "solution" was to disable the firewall on the router which means some settings/security there was triggered. My guess is that it's the "Smart Network connection" that trigger it if the phone have both poor Wi-Fi and 4G. It then jumps back and forward = firewall detect strange behaviour and block. That's why there are so many strange "fix" related to the router - hidden network - no security - disable 5Ghz and so on.
Can someone please test asap as I have a plan But if it's not this to test
