I have this weird problem with the WiFi on the phone. Sometimes it just stops working, websites wont load basically no internet. WiFi icon is shown with exclamation point at that time and in settings it says "internet may not be available".
Internet is ok since I can use it on the PC.. I can solve the problem if I turn off and on WiFi or after a minute or so it comes back by itself.
This happened not only with the S9+.
How can I find whats causing the problem since it happens randomly??

Compatibility issue with some routers.
I encountered same issue with my broadband service provider's router.
Tried to test with every possible WiFi settings, change channels, change band, change WPA settings, etc. but it still intermittently showing exclamation mark, sometimes no exclamation mark, but only up arrow light is on.
Once I change the router to another brand and model, it works perfectly fine till now.

Hi all.
A per my post in this thread. http://forum.xda-developers.com/showthread.php?t=1117077
Code:
Hi all. I also have weak signal problem as well as fon router issue. The signal strength isn't as bad as being mentioned above, but still could be better.
But with my fon I can connect and connection is as showing connected, but I can't browse or have any connection to Internet whatsoever. When connecting to fon both lights on the router start flickering like normal and once connected when browsing or going to market for apps just one light blinks, when both should under normal activity.
Also I get this error message " a network error has occurred. retry or cancel and return to previous screen." when I try going to market.
I've tried setting security to none and wpa and still same no net.:confused:
Now some personal thoughts with experience with Linux and wifi. I think the problem is with driver or the firmware of wifi card on GS2. I had netgear card even thought it was claimed to work with Linux it kept on overheating and dropping connections with weak signal and every time I had to patch it to make it work properly, Many have reported same issues with other devices with Linux when it was claimed that devices should be working but were not.
My question is there anything I can do other than I haven't so far to check the problem why am not getting Internet through my fon router? Or any other checks I can do other than wifi tools I downloaded?
Thanks

Thats the router not the phone .
Set router to no security or passwords .
DELETE ROUTER WIFI FROM PHONE REBOOT AND RESET UP WIFI .

Hi, I've tried that still the same problem.
And it's not the router since every other device connects to it and many laptops and computers, without any problem.
Like I said I've tried it with wpa wep and no security just open, and still no Internet, even though it's showing as connected with signal bars at the top of the phone.
I've tried the phone with friends routers and it works on those. But not with mine which is Fonera.
Does anyone know what chip is used for wifi in these phones?
In case anyone else is wondering it's Samsung's own brand.
manufacturer=Samsung Electronics
device_type=1-0050F204-1
1.Hello guys. I have some weird problem. I can't turn on my data/3g connection. When i press turn-off button and i press turn od data connection nothing happens, my apn settings is good, i checked it twice, i tried to turn it in settings too, but nothing happened, and the most weird thing is that a week ago it was working very good;/
2.I've made one thread instead of two. My second problem is when i back to stock(custom stock,or normal stock) i try to connect to my ad hoc wirless what i've created by connectify, but android dont see my connection, any solution for this 2 problems? please guys its not good to not have internet connection on smartphone
That sounds like a carrier problem. I'm having problem with 3G my self (Not like I care since I'm always on Edge) but I asked my friend and he told me that the network running some tests.
If worse come to worse, do a factory reset. As for your other problem, I don't really understand it. xD
Hi i went from stock ics on my ray to cm9 by followingnexact step by step guide provided by cm9. Used their kernel as well. Have never modded my phone before. Having a small problem with wifi though. After my phone has been asleep for a while, if i wake it up the wifi icon in status bar is no longer blue its a dark grey and i can no longer browse anything or use the internet. Ive tried rebooting. I did the whole wipe cache etc when installing cm9. In wifi settings in advanced ive also left the setting to "leave wifi on when sleep" checked. If i turn off and on the wifi connection the phone ofcourse is able to reconnect again the icon is blue and i can connect. It not jsut a one off thing its been happening since i isntalled the rom.
If i wakek from sleep a few minutes later i have no issue with wifi. Its only when its been sleep for a while do i have this issue.
Any solutions?
I have the exact same problem but for me it's even bigger, whenever i turn on wifi on my modem, i can connect to internet on my phone, but after awhile i lose my connection completely, on my phone and on my pc also, the only way to get it back is to reset my router and wait for like 5-10minutes...

If its also an issue with your. Pc then your issue might be also the router.
My other devices actually work fine in my case its oky this phone that has issues. Macbook iphone ipad nexus s no problems with those.
Same issue here. I can see available networks but unable to connect. There should be no problem with the wifi router as all my other devices work well and I have tried another router. Now I have to flash back to stock firmware.

Your issue seems more severe than mine. Mine actually connects and works, just that when it wakes from long sleep it wont work until i turn off and on wifi.
I get this problem too, but my problem even worse than yours. My wifi lose it's connection after a while, but the icon on status bar shows it's connected, running ping test, browse, even play store can't be accessed. I pinged the router and got unreachable.
And yeah, this problem occurs when I'm using all ICS based rom..
Anybody has any idea if this is a known problem, or if its just us few having thisissue?

I have same problem. I have SE xperia mini with CM9. WiFi worked fine until yesterday. Now phone can't connect to AP (full signal - try connect -> signal drops down), but sharing 3G internet over WiFi works fine. I cleared dalvik cache, but that didn't help.
Hi
i have a problem with wifi. it remains connected but loses internet access randomly. i found this solution:
"In the wifi networks, select the network you want and select ‘Forget network’
Turn off the wifi
kill all the apps with your task manager
Turn on the wifi again
Connect to the network
Check the internet connectivity
If still the problem exist, switch off the phone and redo the above steps"
it solves the problem, but it happens again after some minutes. actually, i also installed an app named "wifi fixer" which does the above process automatically. when the program is active, it turns the wifi off and on every 2-3 minutes. and the phone has internet access when the program tuns the wifi on.
does anyone know what is the reason of this problem and how to fix it?
thanks in advance
pls i really need help over here
Anyone else having problems reconnecting to a WiFi connection, or even seeing WiFi SSIDs after disconnecting from WiFi?
This happens to me intermittently. I have 5 WiFi SSIDs in my house. 2.4G and 5G from the FIOS router, and the same from a WiFi access point on another floor at the other end of the house, and a Guest network from the AP. I can normally see all of them from any point in the house, as well as half a dozen from nearby neighbors. And my s9+ normally connects, automatically, to my primary 5G connection without any problem.
But occasionally, after being out and coming back home, or after the phone has been asleep for a while, it won' see any SSIDs. Not mine, or the neighbors. I've tried scanning for WiFi networks, turning WiFi off, waiting a few, and turning it back on, but it doesn't see anything, and won't connect. I've even tried manually inputting the name of one of my access points, but the phone won't find it.
Turn on WiFi automatically is on, WiFi power saving mode is off (although I've had the same issue with it turned on), Keep WiFi on during sleep was set to While charging. I've changed it to always, but it will be a while to see if that helps.
The only way I've found to get it to see WiFi networks again is to reboot the phone.
Oh, and other devices, including other Android phones, see all the SSIDs without issue.
Any thoughts or ideas?
I have te same issue here, I can't find a fix.
Mine will not connect to mobile date after I turn my wifi off. I have to reboot the phone in order to be able to make a call or use data. It all seemed to happen when a pop up came on to enable wifi calling. I can't figure out how to turn that off.
I don't have acupp1's issue with mobile data, but I seem to have resolved the WiFi connection issue by not letting the phone turn WiFi off during sleep. Haven't had the problem since I changed that setting.
I got the same problem since I rooted
Been trying to figure out if its a VENDOR Firmware problem or what. I do know that every developer says its a bug with the s9 when rooting. I've personally watch the live log on TWRP when flashing and seen where it mounts the VENDOR Firmware and then unmounted at the end. So it could possibly be a problem between TWRP and the s9 ROMs idk know exactly yet but I'm looking for a solution also. But I'm going to try what you did with your WiFi then report back here.
