I use the ComicRack PC and Android programs to sync comic files to my tablet on my home network. This generally works okay but occasionally the tablet will not connect to the server.
When this occurs, I have tried pinging from my tablet to the PC (using various android network tools like Fing) and the pings fail. In fact, when this happens I can't ping ANYTHING from my tablet, not even localhost. But my network connection is active because I can still get to both my local network files (using ES File Explorer) and the internet just fine.
I have tried resetting my wifi connections, setting static ip addresses, changing from 2.4 to 5 g networks, and a number of other things. The fact that it won't even ping localhost, however, would seem to indicate the problem is with the tablet and not the network.
After a few days (or weeks), it seems to start working again randomly - not from rebooting or anything else, it just does.
I am currently not rooted, running factory rom (see attachment). I'm considering rooting to see if I can get around the problem but since I use Private Mode I've been hesitant to do so.
Any ideas? I seem to remember reading somewhere that Samsung devices occasionally had wifi problems, but don't know if that applies to this issue.
Any help would be appreciated. Thank you.

Hi,
So far the AT&T Tilt has been kicking some serious ass. However, there has been one glitch that I'm hoping someone might know more about.
Twice now, the internet connection has stopped working through the cellular data connection. Connecting through active sync and wi-fi still works. The last time this happened I called Fido (Calgary, Canada), found out that everything was OK on their end and then tried a bunch of connection settings. Doing what they asked me to do didn't solve the problem. Then, seemingly by magic without doing anything in particular, the connection started working again and I could connect to web pages again through IE.
So it has happened again, and I can't to connect to the internet using IE (or any other application). Here is the status so far:
- tried rebooting the device
- been able to connect via wi-fi and active sync
- Installed Microsoft's Network Analyzer application which reports the following: IP address is assigned (cellular connection) and able to ping microsoft's http server (www.microsoft.com ). Note that when I disconnect my data connection the ping to microsoft fails so I believe it is actually reaching the server. There is no MAC address for the cellular network adaptor, but I don't know if this is normal or not. See the attached document which is the log file it generated.
- Tried to connect via Google Maps, Direct push (Exchange), Octro Talk. All of the applications give the same message that the page or service can't be found. It is odd that the Network Analyzer seems to be the only application that can talk to the outside world.
- Also re-ran the diable proxy cab for the Tilt
I didn't play with any of the connection settings prior to this happening so it's hard to tell what is causing the problem.
Thanks in advance,
Alan
Flash your ROM
If you are having the same trouble, I fixed my problem by flashing to an HTC ROM. Screen layout switching is faster now, my network connection is working and the system seems generaly faster. I'm using Dutty's Hybrid test final rom V4. If there is stuff about your tilt that you don't like, and you aren't actually using AT&T as your carier, then I would just ditch their ROM.

I can't get AirDroid to connect using ICS leak 213.
I can't even get my phone to respond to a ping from my laptop on the same network, though I can ping my laptop from my phone on the same network.
Any ideas?

It sounds more like a network/router issue than an AirDroid issue, it worked fine for me in .213 and .215 leaks.
Is your phone on a VPN connection? If yes, then it's possible that your phone has multiple IP addresses and AirDroid is showing one which is not accessible from your laptop.
Did you try both connection methods? Via the local IP and via the AirDroid.com wensite?
No VPN connection.
I tried both by local IP and web.airdroid.com, and checked that the local IP is correct from both About>Status and my router.
If I try to connect just through Chrome, I never get anything. If I try to connect by scanning the QR code through my phone, I can sometimes get it to connect initially and bring my to the AirDroid desktop, but I almost always can't access contacts, messages, etc.
I tried port forwarding 8888 for my local IP, but that didn't seem to make any difference.
The strange thing is that my Touchpad works fine with AirDroid. In the past, I've had some odd Wifi issues with both my Droid 4 and my Droid 3, e.g. adding an Exchange account won't complete setup if I'm using wifi on either of those phones (on GB and ICS), but it has worked fine on Android devices without cellular radios (my Touchpad and Archos 101).
It appears like it's a network/router issue, but at the same time appears like it's not.

There could be a clue right here. Do you have a mobile data subscription?
If yes, then perhaps there are some very small WiFi drops which cause Android to try to connect to mobile data instead of WiFi, and the time it spends without the local IP might just be enough to impact AirDroid performance.
You could try the following:
Put the phone in Airplane Mode to disable all wireless connections
Manually enable WiFi - this is possible without disabling Airplane Mode
Now you are on a pure WiFi connection, no mobile data or Bluetooth PAN to interfere. Does that improve AirDroid's behaviour?
Also, if you know how your router works, you can give the Droid 4 a fixed IP address to avoid the IP changing when there is any network hiccup. Most modern routers usually seem to remember which IP they assigned to a device via DHCP anyway (at least for a limited amount of time) but it's worth a shot.
No such luck with the Airplane Mode/Wifi. I outright turning the cell radio off with Phone Info too, still didn't work.
With DD-WRT, my router will keep IPs and MACs associated, so it's not that the IP is changing.
If I reboot the phone, it'll work a little bit initially but eventually stop working and I won't be able to ping it either.
Hi guys,
My phone: Samsung Galaxy S3, GT-I9305, Android 4.1.2
I changed the ISP (Germany: To Unitymedia) and are now supposed to use a cable modem which as well serves as wifi router. My hardware is TC7200 (Technicolor).
After setting up everything, the wifi connection to Win 7 laptop and Apple iPhone/iPad is working fine (also LAN connection to laptop of course).
The S3 showed a funny behavior: It is possible to establish a wifi connection and it gets IP address assigned. Default gateway, DNS server looks all fine. However, this is only the wifi signal but not an internet connection. It is not possible to reach any website.
The strange thing: If the google site is cached (from a different connection and then switching back to this problematic one) I can run a google search and get results displayed. However, it is not possible to open any websites displayed as results here.
I tried several things based on suggestions in the net, like restarting the s§, using static IP address, changing wifi ports, disabling wifi encryption completely, restart the router, factory reset the modem/router. Finally I performed a factory data reset for the S3 but this as well, like all other things, did not help. The phone was never rooted until before yesterdays factory reset, because I wanted to use Titanium Backup which requires root rights.
Of course, in all other wifi networks so far, this S3 works absolutely fine!
I am not sure if this matters at all, but with the new ISP I got an IPv6 IP address while before I had IPv4.
To be honest, it might simply be a hardware problem which has to be fixed by Firmware upgrade by ISP. This problem is sort of known to them and when I called in they promised a firmware update in November. But anyway, it would be interesting to understand more about it and usually there is a solution for everything Nevertheless, I couldn't find a solution in any forum yet.
Any suggestions / ideas welcome.
Thanks!
EDIT:
Post already moved.
Reads like wrong settings more than hardware .
WiFi is kernel you can flash a kernel .
But i would reboot router and phone then set up wifi with no security first .
I have been having issues where i am connected to the wifi but the device stops passing any traffic. I have fing installed and i can't ping any other devices on my network. I know its just my phone because i have my work phone and tablet connected to the wifi and they still work fine browsing webpages, watching movies etc while the droid turbo can no longer communicate with the local lan or out to the internet. If i switch the wifi off then on again it will reconnect and then work normally. I can then ping devices on the local lan and access pages on the internet. This has happened a number of times now since i got the device.
Edit: I just updated the phone and still get the issue. I have a cisco WAP at home, we have cisco WAP's at work which i will test tomorrow. If this thing still has issues i am just going to swap it out for a Note 4.

I've been seeing issues with Cisco wlans too.
Sent from my XT1254 using XDA Free mobile app
so it looks like it works good at work, something with my home cisco ap and this phone as all other devices at home work ok.

Yeah this phone does not seem to like my router for some reason. Keep in mind I'm not a networking expert, but I've tried every combination of options and settings every which way from Sunday and I just can't get the thing to work. When I do connect the phone to my wifi it kills the the connection on every device in the house. At first I though it was just a wireless thing, but even the downstairs computer which is plugged in directly to the router doesn't work. Then as soon as I disconnect the phone every device works again. I thought maybe there was too many devices, so I disconnected all but the downstairs computer, still had the issue when I connected the Turbo. I've tried just turning off the WPA2 and just having an open system, I've tried connecting the phone using a WPS pin (This one actually worked for a good 5 minutes before crapping out and hasn't worked since). On the advanced options of the phone I tried an automatic IP as opposed to the default DHCP setting (This also worked for a good 5 minutes before not working ever again). I've tried limiting it to just one frequency band. I have tried so many different things and I just cannot make this phone work on my router. And I know it's my router because the phone works fine at work.
phone: Droid Turbo
Router : Asus rt-ac66r
yup within ten minutes of getting home, the device no longer passes traffic. My work S5 still works fine at home and so does my samsung tablet. The device worked on wifi all day at work on our enterprise wpa2 network no issues. I tried doing static ip at home, changing to 2.4 ghz, trying new ssid. Not sure what else to do with this thing...

I posted a comment on Motorola's forum where people are discussing their wifi issues... And my work around. I currently beleive its a software issue and can be fixed via update. Also, today I found (it appears) that the longer the phone goes without a reboot, the shorter amount of the it appears to go with out needing the wifi card reset.

My work around fix...
First, over night my wifes phone now behaves just like mine. It now connects to wifi and after sometime passes it no longer passes data (but stays connected). I needed a way to auto disable/enable the card... I installed Tasker. I have it set to check every 15 minutes, if the phone is connected to WiFi, to disable then enable the WiFi card. I use WifiMatic to enable the wifi card when the phone is connected to the cellular tower that is near my house. (Doing this by GPS uses more battery power...) Using Tasker with the rule to verify its connected to wifi first helps not enabling wifi if its nit needed and lets WifiMatic enable/disable it as needed.

I own an OnePlus 3T running Open Beta 8, and I've come across a rather strange problem with the Wi-Fi.
It is basically a problem with this one network. It has worked fine with all others I've had it on. It'll connect to the router but will have no Internet access, a Wi-Fi fixer tool I used reports Internet as disconnected and it also fails the DNS ping tests. When you connect after a while there'll be Internet access for a minute or so but then it disconnects again. What's interesting about this problem is, that other devices on this network lose their Internet connectivity as well. Upon disconnecting the phone, they regain Internet access.
I've tried all the standard fixes, resetting the router, resetting the phone -- which solves the problem for about a day or so but it comes back around. I've changed the IP to static and back. Assigned DNS manually. Even attempted creating a hotspot with another device connected to the network. And tried the WiFi Doctor app, but nothing has worked so far. This problem was also persistent in Open Beta 7
