[Q] Nook Color - Wi-Fi connected but can't add google account or browse web.

I just loaded phiremod 6.3 onto my Nook Color. When I attempt to add my google acount, I get "Can't establish a reliable data connection to the server." When I click on the market app, I get "Could not launch the requested activity." When I open the internet browser, I get "Web page not available."
I have a strong wi-fi signal that my computer, cell phone, and another Nook Color are able to use without problems. The tablet says that I am connected, the signal is strong, and I'm not in airplane mode. I can't seem to find any posts that address the problem of not being able to add a google account AND not being able to browse the web with a solid wi-fi connection.
This is my first post so let me know if I put this in the right category and if I need to add any additional information.
Thanks in advance.

I thought this might be a problem with the newly released phiremod 6.3 because my device was working just fine on 6.2. However, I just flashed back to 6.2 and experienced the same problems. I can't make sense of this especially since the device is successfully connecting to the wi-fi.

Have you verified that if you reboot a PC on the same wireless network it works properly? Could your router have run out of available IP addresses? Possibly not handing out DHCP properly? Maybe your DNS servers you have listed in the Router were down temporarily and your computer was using cached information previously. Several scenarios that could be valid here. I'd like to find out first if a PC on the same wireless, connected wirelessly, is working.
Also do you have MAC address filtering on the network? So you're connecting w/ no issues but not able to surf because it's blocked.
If you go to the admin GUI of the router do you see the NC in the DHCP client table after you are successfully connected to the WiFi network?
Good Luck, I'll try to think of any other things.

Thanks for your reply Deltabear.
I share a wireless connection with my apartment landlord so I don't have access to the actual router. However, I can tell you that his computer is the only other one that uses it, and only for a few hours during the day. I rebooted my pc, and it's having no problems with the wireless connection. I rebooted my other Nook Color, and it too has no problem with the wireless connection.
I just remembered that when I loaded phiremod 6.2 it connected to the wi-fi. Then I experienced a boot loop when I tried to flash 6.3. I still have no idea what went wrong when I flashed 6.3, but everything went downhill from there. I ended up trying to revert back to stock, but instead of a bootloop at "Touch the future of reading" I got stuck in a bootloop at the N. I performed the 8x method and received an OTA update, but remained in the bootloop. At this point I decided to just go back to trying to flash phiremod 6.3, and this time it worked...except for the wacky wi-fi problem.

When you go into settings>Wi-Fi settings Is the router listed with connected underneath it? Or does it keep saying 'connecting'?
If it says connected press the router name and it should bring up a box in the middle of the screen with
Status
Security
Signal Strength
Link speed
IP address
What does it say under each?

Well the problem seems to be resolved but I don't know how or why. I turned the Nook's wi-fi off, and when I turned it back on I was able to add my google account, browse the web, and open the market. I know turned the wi-fi off and on several times yesterday so I am still perplexed as to why it seems to be working now.
To answer your question DreamingWolf, the router always said it was connected. I don't remember what the info was for it when I was having the problem, but I know I looked at it a few times and nothing seemed unusual there...I am however a noob.

[Q] WIFI not working anymore.

Hi guys.
first my wifi became unreliable, it disconnected, didn´t reconnect sometimes etc...
now, it´s not working anymore at all.
when i go to wi-fi settings it says turning on, then the red arrow appears, then immediately it says turning off. down there comes a message "unable to scan for networks"
i searched the whole forum, but didn´t find a simlar problem.
i reseted it to factory, didn´t help.
it can´t be a router problem, ´cause all the other devices on the wifi work, even my friends myt4G.
any tricks or ideas anyone?
i got this form a friend in the states, bought last december, he ment, in the US they have mostly only 90 days warranty, in germany we got 2 years.. is this true..?
stock rom. 2.3

Try chaning the channel on your Wifi Router. Most of the new routers you can go to routerlogin.net from a computer that is connected to the router and change the settings. I had the same problem and it appeared all of my neighbors were using the same channels i was. I move to a different one and haven't had a problem since. It will not affect the SSID or the password So all of your login it stuff will stay the same. Any WAN connected device just might lose signal for a second or two while the router changes channels.

thx. channel was on auto. changed it to 11 out of 13. didn´t help. also, i have only 3 wifis in my neighbourhood, i can get with my pc. on the htc, it shows only mine + the direct neighbour..
it seems that wasn´t he prob here...
could it be a hardwareprob? anyone any knowhow on american warranty?
the wi-fi button is almost not responding anymore.. when i turn it off, it turns itself on again, when i go into wifi settings, ist keeps truning on and off again in an endless loop....
edit: tethering does also not work anymore. when i click on portable wif hotspot, it says error...
hardwarefailure?

i found these guys who have the same problems.

seems to be a gingerbreadissue... perhaps i´ll try downgrading first.

so i downgraded to 2.2.1 and it worked. got to bed, woke up, not working anymore "unable to scan for networks" again

Samsung S4 I9505 Can't see any wifi networks

I have a Samung Galaxy S4, GT-I9505, Android Version 7.1.2, using LineageOS 14.1-20180309-NIGHTLY-jfltexx. Baseband version: I9505XXSPQA1. Kernel version 3.4.112-Lineage-ge8d93e0
It has worked fine for months. But on the 1st of July, while a friend was borrowing it, it was all of a sudden unable to see any wifi networks. My friend doesn't know what he did to it as he was just trying to connect his wifi. Now I can't find ANY wifi networks. None at all! All other devices in the house can find and connect to wifi networks and to the home wifi network.
I've tried the following:
1) Restarting the phone
2) Turning on airplane mode and looking for wifi networks.
3) Restarting the router
4) Factory resetting the phone
5) Flashing the same Lineage OS version from the SD card using TWRP.
6) Removing the battery for 1 minute and putting it back in and restarting the phone.
What happens normally?
I go into wifi settings by pressing and holding down on the wifi icon in the notification tray. When I get there, there is a blue moving bar near the top which makes it seem as if it is searching for a network. I still attempt to turn on the wifi using the switch to the top right. There's a message in the middle of the screen saying "Turning Wi-Fi on …" And then it searches and searches. Eventually the "on" and the wifi switch get greyed out and are unresponsive to any touch, but there is a moving blue bar just under it that makes it seem as if it is still searching, but it sees none. If I wait long enough and the phone screen times out and I turn it back on, in wifi settings, at the top it says "off" but the blue bar under it is still moving as if it is searching. If I press the switch, the same thing happens.
If I got into "Configure Wifi" the MAC address is set to 02:00:00:00:00:00 and the IP address is "Unavailable".
Doing all this gives me the impression that it is a hardware issue, not a software one.
But I'm wondering if there are any solutions that I haven't tried, or is there agreement that it is most likely a hardware issue.
My wife took it to a local market to see if they could fix it. The guy went to the TWRP app that was installed and claimed that somehow it had been used to delete the wifi software. It didn't seem right or likely. I don't think he knew what he was talking about.
Can anyone help at all please?

get a new phone lol serranoltexx is old

@amenyahu
Hello, If you have any FULL Backup include EFS, preload etc. Restore. If you don't have backup, you can try flash STOCK ROM using for ex. samfirm - https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647
Also you can use one of thread https://forums.oneplus.com/threads/...-02-00-00-00-00-00-after-3-5-5-update.480733/
Let me know if there is any progress.

Is my wifi chip (hardware) broken? (Lenovo A7600-F)

Hey,
I recently got a used Lenovo A7600-F tablet from my office because they weren't using it anyways.
Everything seems to work perfectly fine - except the wifi connection.
Code:
Model: Lenovo A7600-F
Android: 4.4.2 (no further update available for that model)
Kernel: 3.4.67
Build: A7600F_A442_000_029_150401_ROW
Here is the thing:
I disable/enable wifi
I click my home network and enter the password
Nothing happens for ~2 seconds
"Failed to connect to network" (no "connecting" or similar)
To make sure my WPA2 security isn't the problem, I made an unprotected hotspot on my phone. Absolutely identical problem.
One thing I noticed: The tablet is able to find all the networks around me and updates their signal strength in the list without any problems. As soon as I try to connect to one, it takes around 2 seconds until it says "Failed to connect to network". If I then try again, the message pops up instantly with no delay for all networks. From that moment on, the list also stops updating and can't be refreshed until I turn my wifi off and on again.
I downloaded "Wifi Analyzer" and I can see all the networks' strength values moving. I can close the app, do something else or go to standby and come back to see the values still updating. But as soon as I try to connect to a network, it will give that error again, stop updating the list in the wifi section and Wifi Analyzer will not be able to find any more signals. If I close that app and bring it back up now, the list of networks will remain empty. Same with the networklist on the wifi settings. Turning wifi off and on again resets the whole thing.
In short: My tablet sees all networks around me and updates them, but gives an error ("Failed to connect to network") as soon as I try to connect. Then no more wifi updates until i disable/enable it again.
Factory reset did not help, I let the battery drain and charged it back up - no success! I also tried an app called "Wifi Ruler", which was mentioned to fix a similar problem in a post I found on another forum. Connecting through that has exactly the same effect.
Does anybody have an idea about what is going wrong and what else I could try to fix this?

Moto G6 Plus black screen

Hi
my MG6+ got a black screen out of the blue. Pressing the power button did not help. To connect it to a Windows 10 PC does not help - it tells me that the usb connection does not work. What is really strange that the device is somehow alive. It is logged in my wlan. I can ping it. Is there a way to get the data from the phone or do something to get it work.
I tried to use a usb-c to hdmi cable to connect the phone to my tv but nothing has been displayed on the screen.
Thanks for help

What do you mean by out of the blue?

I meant that the phone stopped working (black screen) without any pre-warnings.

What is strange that the phone is logged into my LAN and I can ping it. A network scan also tells me that this is a device from Motorola Mobility LLC, a Lenovo Company.
