Hi,
I have a LG G3 phone. I'm trying to use Guest mode but it doesn't work. Simply, the Cast icon does not appear in any app. Normal cast (when connected to the wifi network) works.
BEFORE YOU ASK
1) I tried everything the FAQ and the Troubleshooting said, including Factory reset, reboot, wifi and data settings
2) It's not only my problem. Other people with G3/G4 have the same problem:

https://productforums.google.com/fo...hromecast/category$3Areport-a-technical-issue
3) I investigated and found out this in not Chromecast bug but phone bug. In fact, Chromecast creates two wifi networks with hidden SSID which work as a beacon for the phone. You can't see them in wifi network list, but if you download wifi analyzer you can see them (I saw them with a Samsung Galaxy S4) with SSID '?', which means no SSID, and the MAC address following. Well, I installed wifi analyzer on the G3 and they don't appear in the list.So this means that LG G3 and G4 can't see networks with hidden SSID (whereas all other phones can), and this is the cause of the problem. The bug is several months old. Has anybody got a solution/suggestion?

I have recently returned to my apartment with my brand new archos 70. I use WPA2-PSK encryption for my wifi network. at first everything was golden, I could browse the web and whatnot just fine. as of a few days ago, wifi has not been working correctly. my device connects to the network (pulls an ip address from the router) but when I try to browse web pages or open web based apps they hang up and act as if I have no connection. it works fine on other networks (to limit the problem to my network) I have tried doing a factory reset of the device, tried power cycling my router and modem with no luck. I have also changed encryption types to no avail. i have the latest firmware for the gen 8 series. also from time to time during this session of events, sometimes it will connect to the router, then disconnect and reconnect. I have no clue whats going on because I havent changed any router settings since I got back. the only other devices on my wifi network are two laptops. any help would be appreciated.
you mean you restored to the factory settings ran through the start up all over again and it still won't connect to your router? have you tried any other types of connections or routers?
I had this problem just the other night was this close to reformatting the whole thing. but I solve the problem by turning the device off, then holding the reset button while it rebooted to turn it off again, an reinitializing the drivers.
how do you reinitialize the drivers? I did a factory wipe. and it connects, it shows as having network connectivity (even my router lists it as a dhcp client and currently making use of the access point) but no internet functions work. ive connected to other networks fine.
This happened to me when I first got my A70. What I had to do to fix it (after getting incredibly pissed, reformatting twice, and almost returning the thing) was to set it up to use a static IP address on my home wifi network. Don't know if it'll solve your problem, but it works beautifully for me and I'm able to enjoy the device now.
Just remember to uncheck "use static IP address" when you get on other wifi networks.
well, I set up static addressing, gave it a private ip, set up the gateway and dns, and it still wont connect to anything.
If set as wireless N, set as N+G or G only, latest firmware may have trouble connecting to wireless N networks.
na, I dont have it set to n, I have it set to auto which I believe puts it to g with my archos. thing is, it used to work. now it suddenly has problems.
Im beginning to wonder if the archos tablets are just picky about wireless routers. I wouldnt think so...
Upgrade the firmware
Archos published a firmware upgrade to solve this problem (December 2010). The related bug in the release notes is...
Wi-Fi: fix Wi-Fi stuck after a while when using WPA2/AES encryption mode
The new firmware download link is in the Archos website.
you can download the firmware to your computer, copy it to the root directory of the tablet using the USB cable, and run the upgrade process in the tablet.
... or you can use another WiFi network (without WPA2/AES) and download the update in the same tablet
Note: I cannot send the links, however you can use the information to search the links in the internet.
Hey all,
I've had my Galaxy S II GT-i9100M for a bit more than two months now. It's been on ICS 4.0.3 since the first day I got it, and is unrooted.
Wifi was working fine the first month or so that I've had it. However, in the last month, while trying to connect to my university's networks from the wifi settings screen, it will display "connecting" for a long time, then change to "saved", without successfully connecting to the network. Odd thing is, if I turn the wifi on and off repeatedly, it may connect eventually, with around a 5-15% success rate each try. However, there's also a relatively high chance it will automatically disconnect itself within a few minutes.
The school has three main wifi networks: one is unsecured, while two are secured with exactly the same authentication methods (PEAP + MSCHAPv2) and takes the same login credentials. All three have the same problem when I try connecting. It's not a problem with signal strength, either, since my friends nearby can connect using their phone or laptop without any problems.
Here's what I've already tried to do to fix this:
Asked the school's IT helpdesk
Forget both secured networks so the phone can autoconnect to the unsecured one
Tried wifi diagnostic tools, such as Wifi Analyzer and Wifi Fixer, and tried changing to a better channel
Deselected "back up my data" in the Back Up and Reset settings screen, deleting existing wifi settings from Google's servers
Connect using a static IP address rather than DHCP. Either it has the same Connecting->Saved issue, or says something about "avoided a poor connection"
Did a factory reset, including wiping all user data
The wifi has no problems connecting to my home wireless network, and to most, though not all, other public networks I've tried (same problem as above if it doesn't work).
On a somewhat different note: there are two networks (each of which I've only connected to once at most) that are permanently saved on the list of access points; there's actually no way to forget/delete the network. They even survived the hard resets, and are listed before I link the phone to my Google account. Could this be related to the main issue above?
Is there a fix for this issue? Thanks in advance for any suggestions!
One problem I had with Android on 3 devices (LG GT540, LG P920 Optimus 3D, Dell Streak 5), usually with custom roms but rarely on some stock roms, was that the phone wouldn't connect to my Wifi networks (hidden SSID, WPA2, one AES, one TKIP) when Wifi was turned on via widget, notification power widgets or other apps. I would press the Wifi button and wait. Sometimes it would connect after a few minutes, sometimes it wouldn't connect at all. However every time I went to Wifi settings it would find the network and connect within seconds. If I let the network broadcast its SSID it would work normally, it's just the hidden SSID that caused problems for me.
Well, the problem is in the "wifi.supplicant_scan_interval" line. Custom ROMs often increase the interval to 100-150-180 as a battery saving tweak which explains why stock ROMs didn't have this problem for me. Additionally, in all of the (few) cases I found across the Internet with the same problem the common denominator was Cyanogen Mod, even though there were different devices. I deleted the modded line with 180 value from my build.prop and the system reverted to the default value (which I heard is 15), and now wifi connects to my hidden networks just fine when toggled via notification widget.
I wanted to post this somewhere because, as I mentioned above, I saw other people report this problem, but their posts are scattered over the web on different forums, and none of them managed to find a solution (or didn't post it). I only have access to one router that I can configure, so I can't test different routers with the same scenario, to see if it isn't just my router it doesn't connect to in the given conditions, but I hope some people test this and see if it's a universal problem. It would be nice if the few people who use hidden SSID's on their home network can avoid this issue.
I forgot to mention: all my phones that exhibited the problem were running 2.3.5 or 2.3.7.
I can't connect my phone to any wifi. Everytime i try to connect it just give me 3 words "connecting" then "saved" then "disabled". If i activated verbose logging it told me Network_Selection_Disabled_Association_Rejection
Please help me

1) On my backup V30+ which is on stock US998 30b Pie (but doesn't have a SIM card inserted nor even signed into my Google account), it's connected fine to my home Wi-Fi network so I know it's not a stock US998 Pie issue...
2) This happens even on public free Wi-Fi networks? (Here in the U.S. we have McDonalds, Starbucks?) That would give you clue whether it's one particular router or all your phone has problem with. Or possibly problem with the type of encryption you have on your router.
Usually that message means the router is rejecting the device. You just have to figure out why. But is it one router or all?
3) If one particular router, try rebooting the Wi-Fi router itself.
4) Make sure you don't have any kind of router whitelist for certain devices or MAC addresses and your phone is not included. Or that you don't have some older b/g Wi-Fi chipset standard set; this one is not likely but I had that happen for an older Wi-Fi printer when I had "N" or higher set on my router.
5) On the phone, try forgetting the Wi-Fi network and refinding it. Enter in the password again.
6) Almost last, on the phone try the Network Settings Reset. (See screenshot from US998 30b Pie.) It will reset all network settings including Wi-Fi, Bluetooth.
7) Last, try Factory Reset?

Now you're complicating the question with hotspot...
Let's go back to original question:

If you can connect to public WiFi, then you need to figure out the reason you can't connect to other WiFi. Is it one WiFi router in particular?
I gave a checklist of stuff to go through. Rebooting the router itself, making sure you don't have a whitelist set on the router, reset your phone Wi-Fi and Bluetooth settings, or factory resetting the phone.

One thing I noticed that is different between Pie and Oreo Wi-Fi settings is in Wi-Fi Advanced section, in Pie LG removed that stupid setting to turn off Wi-Fi when your Display was off. I don't know of anyone who would ever want that turned on. When my display is off I still want to receive email, I still want to receive messages, I still want my phone connected to the internet.
But in Oreo, that setting is hidden in the Wi-Fi Advanced section, which is some people don't even know exist. Or if they found it one time, may not remember how to get back there.
Hi,
Both myself and my wife's phones worked fine with our previous ISP. We have moved to a place that our old ISP does not provide service to, so had to go with another ISP. All of our devices work fine when connected to WIFI except my wife's android phone (Sony Xperia X Compact, latest stock rom) and my old Android phone (Moto G 4G running Lineage OS 14.1).
When either of us try to connect either of these 2 devices to our WIFI, they connect for a couple of seconds, then disconnect. They go through the following steps and then constantly loop
obtaining IP address
connected no internet
connected
saved
disconnecting
Rinse, lather, repeat, they both keep doing this constantly. Both these devices work fine on other networks and worked with my old ISP, so the devices themselves are physically fine, and all the other devices in my home connect to the new ISP's router fine as well.
Ive done the following to try to resolve the issue
Forget network and join again
Renamed device names
Temporarily disabled wireless encryption on router
Made sure Mac filter on router is off
Assigned static IP address to both devices
Cleared cache on google play services
Connected a 2nd router to main router as an access point using a different SSID
Used WIFI analyzer to see what WIFI channel was being used the least in my neighborhood and changed the channel on the router accordingly
Turned airplane mode on and off
Turned device off for 30 seconds then back on
Reset network settings
None of these steps have worked, the only thing I haven't done is factory reset both devices which my wife isn't prepared to do with her device but I might do with mine. Are there any other steps that might resolve this before I pull my hair out ?.
Thanks in advance.
@J0hnick
1. A Factory Reset doesn't take effects on Android's system settings
2. Android by default always tries to connect to near-by Wi-Fi networks you've connected before. Hence you've to remove saved networks ( i.e. Forget network ), then add new new network ( i.e. Add network & Save)
Have you tried restarting the router?
