Hi folks,
Weird thing happening to me while I'm out of the country on vacation. Being out of the country is probably irrelevant though.
I'm in a hotel that has crappy slow "captive portal" wifi. So, you connect to the SSID without password, and it redirects you to a login page (name/room number), then it provisions the device.
The wifi frequently hangs or disconnects here, and is super slow even when it is working, so I decided to bail and just use my phone's mobile data. So I went into Internet and turned off the wifi. Slid that switch to OFF.
Looked down an hour later when I had trouble connecting to a site and found the wifi was back on and connected to the hotel site. I turned it off again, but shortly the same thing happened again.
Eventually I turned off the other part, where it can scan in the background for improved location etc, and THAT seems to have stopped the problem, but why does the wifi keep turning on and connecting when I've explicitly switched it off?
Bug? Feature?
Bit of a guess... you are on data roaming? If roaming, I bet the phone is looking for "better options" if discovery is on, and it will re-connect if it finds a wifi that it can use. I'll go with buggy-feature.

The problem here may be my old Linksys router (the ubiquitous WRT54G), but my tablet never has this issue, nor have roommates' laptops and PCs. Most of the time, but not always, my phone fails to reconnect to my home network when it wakes from sleep.
Usually I just toggle Wi-Fi off, then back on, and it finds the network. I've never actually gone into network settings to see what's happening there, and of course now that I'm trying to recreate the problem, Wi-Fi's connecting like a champ
Any ideas what's going on here?
Hey guys,
I have a problem with my wifi...
Here is the before: Wifi works about 70% of the time, occasionally the connection would be dropped (as in "no network access", it still said it was connected).
Here is what then happened (in that order): Wanted to find a less crowded channel and installed Wifi Analyzer. Quickly decided that Channel 1 would be cool, browsed to the router configuration on the Desktop machine (LAN connection), changed the channel. Back to home on Android (don't remember whether via the home or back button). Into settings to see whether I would have to rescan or whether it would pick up the change of channel itself. It couldn't connect... It scans and attempts to connect, but doesn't
What I tried:
I restarted the Galaxy. Still couldn't connect.
Deleted the connection and re-entered the passphrase. Still couldn't connect.
Uninstalled Wifi Analyzer. Still couldn't connect.
Restarted device again. Still couldn't connect.
(At some point during all this, probably quite early, the Wifi symbol also stopped showing up in the status bar. Doesn't appear no matter whether Wifi is on or off)
Switched back to the channel I came from. To no avail
Switched of encryption on the Wifi. Still to no avail
Any ideas as to what might have happened and, more importantly, how to fix it? As I said the connection itself has never been the most reliable, but this is a different league
Thank you everyone!

If you haven't tried it yet, reset your router. That fixes the majority of Wi-Fi issues out there. If that doesn't work, it may be your router itself. Certain routers have more issues with mobile phones than others.
You may want to go to a friends house and try connecting to his router and see if you can troubleshoot and isolate the issue. Either way, best of luck...

Damn you sitecom router!!!
Alright, one thing I hadn't tried until now was to restart the router. That fixed everything including (for whatever reason) the lack of the Wifi symbol!!
So if that is possible feel free to delete this thread! I didn't find the option anywhere...
Sorry for the unjustified disturbance

I've been having this problem for about a week now (no wifi problems at all before then). Occasionally when I try to use my phone to access wifi I'll be unable to access the internet (tested using Opera Mobile), even though I'm connected to the network (AirDroid works fine, my phone shows up in the router settings). Turning wifi on and off doesn't fix it. The only solution that I've found is going into airplane mode for a tiny bit (fraction of a second). This fixes it every time, but it's a pain in the ass to have to do a few times a day.
When this first started I thought it might be related to me having changed my wifi sleep policy to when the screen is off, but I put it back to "never" and I'm still having this problem. There doesn't seem to be any pattern to when it happens. It never happened at college (where I was constantly moving around and switching between different routers), and it happens both at my house and at my friends' houses (where we each only have a single router).
I'm rooted with stock 2.3.4 ROM and a kernel with CWM (but otherwise stock, I believe).
Any ideas?
When I deliberately turn off wifi cos there is none available I can use at work, on wake up my phone seems to always drop the 3G connection and attempt to connect to wifi, if there is a known one nearby it says connected to ' xxx hotspot' this happens when wifi is off and the connection doesnt actually get made, it then takes a while for 3G to come back on again, this is annoying as I dont have instant on data as it faffs around trying to connect to wifi when it is meant to be off.
I have a Stock phone, UK Vodafone on XXELLA version.
Is there a setting I have missed as this is starting to really annoy me now.
I wish I had kept my SGS2 as the freezing issues I keep getting and now this wifi make this a poor performing phone for the costs/specs..
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.
