[Q] "Authentication Problem" When Connecting to Wireless - Samsung Galaxy Nexus

I am having issues connecting to wireless using my Galaxy Nexus. I have tried connecting to 3 different WPA2 networks with the same results. All are configured to use WPA2. Each time, I get the following series of events that show up underneath the SSID:
- Authenticating
- Saved
- Connecting
- Authenticating
- Authentication problem
I haven't tried fiddling with the settings of my home or mobile hotspot as I feel it should connect to WPA2 without any problems. Any suggestions?

Are you trying to connect to a 2.4 or 5Ghz?
I was experiencing something similar but only when trying to connect to 5Ghz.
I solved the problem by switching security from WPA2-TKIP to WPA2-AES.

To be honest, I am not sure if its 5GHz or not. I would assume my Nexus One would be broadcasting on the 2.5GHz frequency, but I could be wrong. I'll check when I get home and test that setting change.

[Q] Wifi randomly disconnecting

An issue I am having is:
I will connect my phone to wifi it will connect fine and tell me I am connected.
I could then later on go into the market and try download something I will have wifi bars but the item will pause download. I then come back out to check if my wifi is still connected and it will say authenticating but doesnt change so I then turn the wifi off and back on. It connects again this time when I go back into the market to download something it works fine.
Anyone else have this issue?
Hey guys still having this issue where my wifi looks like its connected but when i go to settings->wireless&networks-> wifi status will say authenticating with wifi.
It only happens me in my house with my router which is a zyxel router doesn't seem to happen in my parents house.
Is there anything I can do to stop this as its really annoying?

Try changing the authentication type of your router's settings. And if you use MAC security for your wifi, you can disable it.

Well it depends on your router but generally it's under Wireless->Security settings. Mine is with WPA-Personal authentication and TKIP algorithm.
Ok just to update this I have resolved the issue of my zyxel router by changing the security type from wpa-psk to wep.
Wep isnt as secure as wpa-psk but it suites consoles and portable devices better. Since I have changed I havnt been disconnected from the wireless.
I would say that your router has a problem with wpa authentication, I wouldn't recommend a wep authentication. If your wifi signal can be detected from the road where you live I could hack into it in about 10min and many other people plus there a custom antennas that can be made to detect signals and get better range etc.
I recommend you get a better router, something from netgear or belkin would do the job to keep your wifi safe and use wpa+wpa2 together with tkip+aes encryption.

[Q] 5 Ghz WiFi impossible on Linksys wrt610n

Hello,
I cannot connect to my AP on 5 Ghz
It sees it, it asks for password, but then disconnect and reconnect endlessly
Any idea why
Cheers.
One X does not support 5GHz wifi. I see only 2.4GHz in official spec
Oups, I thought it could as i can see it
Switch your router to 2.4, and it will work
I thought it was 2.4ghz only cos of the specification too but i can connect to my 5ghz frequency on my Netgear WNDR3700.
I can see and connect to my Netgear 5Ghz WNDR4500 no problem at all.
You guys can tell me what parameters do you use for your 5ghz ?
Thanks.
My router is fairly new, just bought it 2 months ago. I didnt change any of the settings, just plug & play. Even didnt change the router password.
The problem is with Linksys router's wireless .
even in my house we used to have a Linksys router , kept on disconnected when over 3 devices are connected to it , keeps on disconnected every 2-3 minutes really.
changed the router , and everything is smooth now

WIFI Channel 44
WPA2 AES encryption
Up to 300 Mbps speed setting
5Ghz a/n network types.
That's all the settings that i've configured, although it works out of the box with stock netgear settings too.......

I have seen some places (specs) where is doesn't show the 5GHz, but the phone supports it.

I have tried to double check this spec on the HTC offical website and it does indicate this phone supports WiFi 5Ghz, as it is with Wi-Fi 802.11 a/b/g/n
htc.com/us/products/htconex-att#tech-specs
however, i have tried to link with a DLink router, DIR-857, and it sees the 2.4Ghz SSID and could connect without any problem, however, not able to see 5Ghz SSID though, i have also tried to set no security and with different channels but seems not have any lucky to this.
i am wondering is there any particular setting to the phone or router double checked with customer service but seem not really help, only ask me to change and try with another AP or router.....
I'm connected to my 802.11a AP with no problems at all. Ditto for 802.11g. I don't have 802.11n here so no idea if that affects it or not.
I didn't need to do anything special on the phone. The AP is a Cisco AP1242AG and it has the usual configuration with WPA2-PSK.

[Q] Wi-fi N connection to Dlink DIR-655

I can't get my Note II to connect to my Dlink DIR-655 running in N-Only mode. My Blackberry Torch would connect and my laptop has never had an issue either. I have not changed anything recently and have been using this router with it's current settings for over a year without issue. The N2 sees the wi-fi network but, fails to connect once the password is entered (password verified). I can connect to other G mode wi-fi routers just fine.
DIR-655
Firmware Version: 1.35NA
Hardware Version: A1/A2
802.11n - Only
40MHz
WPA2 + AES
Anybody else experiencing this problem?

Hi 09GraySilverBusa
I have a DIR-825 and I had almost the same problem with my note 2 but I kept getting the reauthorizing problem. I went to dlink and posted there and the thing that finally worked for me was to change from AES to TKIP.
I have my 2.4 ghz band set at n and g
Auto 20/40 mhz
Auto (WPA or WPA2)
5GHz band is set to n only with all the other settings the same.
Hope this helps

Thanks but, I suspect your Note II is connecting via G mode. Also running in N only mode I can't select TKIP instead of AES. I'll try posting in the D-Link forum.

[Q] WiFi problems...

Anyone having trouble with WiFi? With my home router it just keeps cycling between "Authenticating" and "Obtaining IP Address". It will connect with my Nexus 4 if I use my N4 to create a WiFi hotspot. My old N7 connects to this router just fine. It has full bars and is using WPA/WPA2 PSK security. I tried WPS and it didn't work either. Anyone else having issues or have any ideas? I want to root this, but I need to make sure the wireless is working correctly first.
Edit: It appears to work correctly if I switch to 2.4 GHZ mode, but will not connect correctly under Auto or 5GHZ mode. Curious if anyone else is having this problem.

WiFi dropping out unable to reconnect

I'm having problems with WiFi on my 5x. The connection drops intermittently and refuses to reconnect. When I go into the WiFi settings it shows "authentication problem" although the settings have not changed. Sometimes it will reconnect after 10-15 minutes. Rebooting the phone always resolves the problem.
I have both a 2.4ghz and 5ghz access point (dual band router). The phone has problems connecting to both. I have other devices connected to the same access points working fine when the 5x disconnects.
I've also noticed the WiFi connection reporting no internet connection on and off as well, but again other devices are connected just fine.
Is anyone else having similar problems?
My Wi-Fi works flawlessly. That said, I encourage you to update the firmware on your wireless access point/router and see if that resolves the issue. If not, you can try using the legacy DHCP client on your phone by going into Settings, Developer options and turning it on there under Networking.
Good luck.
I'm running openwrt on a tp-link Archer c7. I'll give the legacy DHCP client a try. Thanks.

@jeffmhasty , any update? I have the same issue. Unfortunately I have to reboot my Nexus to fix WiFi connection. Tried legacy DHCP client, tried disable IPv6 connection, nothing helps.
I have router with openwrt too.. Thanks for reply.
Legacy DHCP seemed to work for a while, but it ended up in the same state even with it on. I have it off now, and haven't had any problems with WiFi for a few weeks. I played around with some settings in OpenWRT, but I'm not sure that actually helped anything. The only setting I can remember changing for sure is enabling DHCP and DNS -> General -> Authoritative.

@jeffmhasty I found fix from Openwrt developers- it looks like there is/was an issue with Atheros driver in combination with Qualcomm chipset in Nexus 5X, look at here:
https://dev.openwrt.org/changeset/47469
https://dev.openwrt.org/ticket/20854
https://dev.openwrt.org/changeset/47984
I am facing the same issue of WiFi connection dropping. I observed this after turning off the WiFi scanning under the location setting.
Re-enabling the scanning fixed the issue.
Can anybody explain this behavior?
Also I want to turn the WiFi scanning off and still not get a connection drop.
How do i achieve it?
Sounds like same problem I'm having. I have an archer C5 at home and and Linksys E3000 at work that I have problems with. It seems to have only started since the 6.0.1 OTA. My wifi seems to connect fine, but sometimes shows the limited connectivity warning.
I've just started having this problem as well. I agree, it seems like it's started with the recent security patch (was that 6.0.1?). Mine gets stuck saying it's trying to get an IP address, so presumably something in the DHCP aquisition. I have 3 different APs in my house, but only one is responsible for issuing addresses. That is an Asus RT-N66U running Tomato USB.
It had to be the last ota update that's when it started for my ...kicking me off networks I've been on everyday including my home router ....I do not believe the router is the issue at all ....its the software in our phone
