[Q] One device has connection problem, but not others - AirDroid

Hello,
Airdroid works fine on several devices here (my phone, my son's phone, my mother's tablet), but is very picky on my mother's phone.
All devices are connected on the same wifi network.
She has a samsung GT-S5839i. Here's what happens:
First, after installation, connection was ok.
Next day, no connection, the browser could not reach the phone. My phone could connect (over same wifi network, same browser on my PC). I restarted her phone, launched Airdroid : works fine.
Today, one day later: everything the same: not working at first, I had to reboot her phone.
So she has to reboot her phone to use Airdroid, that's not very convenient
What could cause this? How can I investigate this issue?
Thanks a lot ^_^

Hi,
Sorry to hear you're having trouble building connection for Samsung GT-S5839i. To help us find out what's happening, would you please tell us what's your Connection Mode, Android version and your AirDroid account?
And if you're using LAN Connection Mode, you can check if the network connection works fine on your GT-S5839i.

A510 NO internet connection

A510 connected to router, can easily access files stored on lan, but I can't open any webpage ("Webpage not available", same with gmail or facebook). If I conect my HTC Desire over wi-fi to the same network, internet surfing works without any problem. I also tried connect to other network, turn off - on tablet but nothing new.
I am sure that yesterday it worked ok, but after that was only using lan connection.
Last night I have rooted tablet (using simple method), installed SuperUser, then TitaniumBackup, Asphalt, GTA3 and Kineticalc (from mobilism) and at the end tried to use cifmanager (without any success). I do not know if anything there make something wrong.
What to do?

Now I made reset under settings and at first boot it asks to sign in to google but I can not do that since network connection is still not working
Ive tried a few apps that didnt connect properly after bieng on another network for some time, particularly apps that needed authentication like Dropsync, and I sorted it by having my tablet connect to the internet through my mobile data connection. I dont know if your HTC Desire has that, but on my Sensation I just started mobile data and wifi hotspot, connected my Tab to it and was able to get online with any app on the tab. When switching back the Tab to my home wifi, everything worked as it should.
Might be a dns reset issue, that the Tab is forced to do on connecting to another network, it has to, but I cant say for sure that this trick will help you..

No connectivity to only 1 LAN PC

Hey so I rooted my Nexus 5 recently and pretty soon after I noticed that I can't connect to my main computer on my LAN. I use apps like airdroid and it refuses to connect over LAN mode and goes to remote mode. If I use terminal and busybox to send out pings, I can ping my router, along with most other devices on the LAN, but just not this computer. Firewall is turned off for testing purposes. I use apps like XBMC remote almost daily so this is become sort of a nuisance. I had a Galaxy Nexus before and it didn't have any of these problems. Any ideas?
I dug out my Galaxy Nexus and tried it again. Same issues. So I'm chalking this up as more of a network issue than a device issue. Still, anyone have any ideas as to why this is happening?
Sorry for the triple post guys. I solved the problem though. Turns out it was just my ****ty Telus all-in-one router acting up and was refusing to forward packets to my computer. Rebooted it and all is good again. Suppose this thread can be closed if that's something you guys do here.

[Q] Phone will not connect to Wi-Fi at work

I’ve received my One on Monday. It’s working very well except it won’t connect to the Wi-Fi network at my work place.
1) The phone connects without problems to my Wi-Fi at home
2) I have the exact same Wi-Fi settings for the work network than the ones on my other android phone which was connecting just fine to this network.
I’ve rooted the phone but otherwise I’ve not changed either the ROM or the kernel.​Any idea what might cause this or what I could do to fix it?

Phone connected to WiFi but not IP being pushed and Internet not working

Hello XDA Members,
I am having a mysterious issue that has been very annoying. I have an EVO Wingle Wifi Device for Internet from PTCL in Pakistan.
It was working fine a couple days ago, my phone used to connect find to the wifi of the device and I was able to use internet on the phone, but all of a sudden one day, something went wrong.
Now the issue is that:
1. The phone can connect to the wifi, and it says "connected" but the device is not pushing the phone an IP anymore, it says "::1" in that place, and also the internet is not working on the phone.
2. On the devices stats page, I can see all other devices connected to the device, but not the phone. The wifi limit is 5, and I only usually have my laptop connected with it.
3. I also have tried to use a static IP on the phone like 192.168.1.128 and manually set it on the phone, and the phone still connects to the wifi, and it shows the IP, but still the internet doesn't work and the device doesn't register the phone in it's stats.
4. All other devices can connected and work fine with the wifi, with the internet working on all of them.
5. The phone works with any other wifi connection fine, just not with this device.
I have tried to:
1. Factory Reset my device, it didn't solve the issue.
2. Forget WiFi many times on phone, used different passwords, clear settings, etc.
3. Reset the phone, whitelisting phones MAC address on the device.
4. Used wifi fix apps from google play without any results.
But nothing seems to be fixing the issue.
Now I am at loss, I don't know what to do anymore, can anyone help?
Device: 9.1 Evo Wingle WiFi Device, PTCL.
Phone: Samsung S3 Verizon - Running KitKat 4.4 with CustomROM (SUPERLIGHTROM V5) with Safestrap, and rooted phone.

VPN suddenly won't connect through Google wifi

hi....I don't know where to post this, but I need help.
up until 3 days ago, I had no problem using my VPN through Google wifi. worked beautifully.
however, for the least 3 days, I cannot get connected. I've tried both on my android phone (Galaxy note 8) and my android tablet (Galaxy tab a; both android v9). spent an hour+ with VPN support, then realized that I COULD get connected on phone if I turned Google wifi off (just used phone data). i still can't get connect with tablet, which is only wifi.
for some reason, Google wifi is blocking the VPN connection (recent update?). why? and more importantly, how do i fix it?
thank you!
