Hello,
Why is this happening:
I'm using xoom 3g with hsdpa -connection. If I ping my xoom's ip from outside (or another address from the console) to maintain hsdpa -connection, the browser does not work as it should.
Sites do not load completely; the browser 'loading bar' stops in the middle and nothing happens. About only 1 image is loaded from the sites then nothing. But the ping keeps getting responses. I'm a bit confused why this is happening

Ever heard of a DOS attack? It's where multiple clients ping a host on the internet so that there's so much traffic going to the host that it can't operate properly. Now, most hosts on the internet have a decent connection meaning it takes a lot to bring them down. You're on a 3G connection... which are flakey at the best of times, nevermind if someone's constantly jamming icmp packets down it.
Of course, I could be wrong, but your symptoms definitely sound like that's what's happening.
Why do you have a constant ping going anyway?
Thnx for your quick response!
The host that I'm pinging from the xoom is google.fi and when I'm pinging xoom, it's from my own server that is not under dos attack. I know that 3G connection can be a poor one but that's not the case imo. At least my ping response times are 20-40ms.
I did a fast testing with the new firefox5 and this effect does not happen with it. I have to do some more fiddling with firefox.
The reason why I'm pinging constantly is to maintain HSDPA -connection and prevent xoom from roaming when I'm actually using the device like browsing the web and using gtalk. The roaming happens way too quickly (xoom drops to 3g from hsdpa)

Does that actually work? I see no reason why it should.
ed. I can't even reproduce what you're seeing. It may be that we're on different carriers, but my device isn't responding to pings from the world while on mobile data.
It's normal for HS*PA to fall back on 3G sometimes when it can't actually maintain a HS*PA connection.

Yeah I thought the whole point of it falling back to 3G was because the wasn't capable of holding an HSPDA connection? Certainly if I'm travelling I get a mixture of 3G and H... and sometimes still GPRS (*shakes fist at Orange*).

Yes it works with my provider anyway.. On the status bar when roaming/doing nothing xoom says that my connection is '3G.' When I start to ping it (or from it) the connection changes to HSDPA; logo changes to 'H' and it prevents it from falling back to 3G. Everything works much faster when the roaming doesn't happen and for some reason even the conn dies sometimes (no internet connection) when it keeps changing it back and worth.
Didn't have too much time to test it with firefox5, but it seems that this doesn't happen with it.. but firefox itselfs crashes a bit too often Maybe this whole "thing" is fixed in honeycomb 3.1.

I noticed something with the G2X the other day that I never noticed with any other phone I had before, althought this is my first android. But I've noticed that if I have Wifi on with a weak connection with 4G (1 bar), it will not switch to the stronger Wifi signal for data, but rather keep trying to do things over the radio. Has anyone else seen/noticed this, and any idea how to make it hand off to the stronger connection?
I believe the my account app or something like that only works with phone data and not with wifi. Do a search it was posted somewhere in here about it. To figure it out further I would kill all running process you don't need under settings/application. Then try connecting wifi. I find myself running into a few bumps with wifi calling. Please could you provide more info like what version of android/ or rom. And any apps you may have? I have some ideas but could use more info to help trouble shoot.

Good point - more information is better . I'm using stock froyo, rooted with things like my account and I have the My Account and other similar things frozen.
This issue is something I noticed in my house. For example, if I go into the bathroom, I'll watch my bars drop to 1. So I then turn on Wifi, and it connects to Wifi, but then if I load up the browser to access the web, or market, etc. It'll still be using the radio instead of detecting the stronger signal and switching to that. So that's the biggest issue now. It's just weird it doesn't sense the stronger connection is there and go.
Try this. Stand near the wireless router and connect to you wifi...does it connect every thing correctly? ( ie wifi radio wifi calling if you use it and does the cellular bar shade out? If it all cconects correctly was away from the router towards your dead zone. As you walk slowly watch and see what your radio's do. This to see signal strength. I am sure they have an app that can show signal strength. I say we try this first to see if we can get it to connection properly. If your unable to connect properly I would try fixing permissions and possible dalvic wipe. I will be honest I am not an android guru like some but want to learn. I was a windows mobile user till a few months back. I will help you the best I can.

Hi guys
I'm well known for being quite wordy. I'll try to keep it short with this one. Summary: my data stream is interrupted, apps don't get or lose connection.
Network situation:
Signal strength ok up to excellent (~75-90dBm). Technology usually UMTS/HSPA, problem also occurs on GPRS/EDGE though. Happens when stationary but equally when on the move.
Devices affected:
HTC DesireZ, Samsung Galaxy Note, Samsung Galaxy SII, Motorola Defy, HTC Desire HD. Occurred first when I was using the DesireZ but is still happening now on the Galaxy Note.
Issue/problem description:
Despite the steady and good connection to the network and of course an open data connection - we speak of Android - the actual data flow seems to be/get interrupted all the time.
When I hit a window of "data deadness" the browser doesn't load pages, online-apps refuse to work showing a spinning busy/wait indicator and eventually timing out, Maps doesn't load content, Tapatalk throws an error, in short: any online bound activity comes to a halt, despite the connection being "up".
Bad issue: when at some point the timing is really bad, GMail push gets interrupted. Worst issue: GTalk is unable to stay online. Basically whenever I load/bring to foreground GTalk, it has to reconnect. It also loses connection though when in foreground. Wake up the device, GTalk greys out the contact list and first has to reconnect. This can happen after 5 minutes, but also several times within a minute. There is no indication of any interruption or error, data just doesn't flow.
I discussed the issue several times with my providers network engineers, they are unable to help at this point. They observed my device and are happy to report that wherever I was, I had good signal and am usually connected to their HSPA network. No anomalies. The engineer yesterday said they rebooted all antennas around where I am the most, they all rebooted and came back up without any error, so their network seems to be fine, from his perspective. Since it does not only happen to me, but to several friends and relatives, and on several devices, at very different locations (one friend lives 150km away) it must be something they changed in the network. The outages don't happen when connected via WIFI, Talk is rock-solid then, they also don't happen when using another operator. One friend even tested with a pre-pay card from another operator in another country: stable connection, all the time.
So what I'm looking for is some kind of a possibility to collect logs, network data, anything to somehow try to pin down the issue and solve it. It's not like the operator is unwilling to help, he said he is just running out of options. And since it works brilliantly via WIFI, on other operators and did work for years on my operator until last August/September-ish, it must somehow be solvable. It's not the services, it's the network.
Anyone any options or ideas? Maybe an insider which has an idea what it could be?

Does anyone know of a possibility to steadily log network connectivity, data streams/flow, network stability or interruptions? It is turning me crazy and I don't know how to help my network provider help me. Duh...
The signal strength indicator will usually change colors when a internet connection is lost or being established. I believe the default colors are green for connected or grey for disconnected. On Motoblur its blue for connected and white for disconnected so the colors may very.
When it drops is the indicator changing colors or is data just dropping?
...not on Samsung-ROM's. The ability is not implemented in Samsung-ROM's.
I was running Cyanogenmod on a DesireZ, where the indicator is implemented. I also suffered the same problem on the DesireZ. The indicator never changed.
As described above, the data connection to the network is up constantly, indicated by a never-changing G, E, 3G or H+ indicator. Signal levels are good or excellent. There is no feedback by the system or obvious indication that the connection is interrupted. I do notice it only by (online) apps suffering a time-out situation, usually only when actually in use and in front. As for example:
- (mentioned) Talk having to re-sign in when being brought to front all couple minutes.
- (mentioned) GMail losing server-connection and push-capability.
- (mentioned) When trying to browse a page in the browser.
- When pulling up a train table on the public transport app.
- When buying a "mobile-ticket" in the same app, often while verifying my CCard details.
- (mentioned) When browsing various forums with Tapatalk.
- Trying to load videos in YouTube app.
Uuuhm... running out of examples
Anyone else with WiFi issues? 90% of the time I have no problems but 10% of the time it seems the connection hangs. Data transfer will pause and resume 30 secs or a minute later. I have tested this with speed test and was able to reproduce. Happens on both my 2ghz and 5ghz networks. I am rooted but I'm going to do a factory reset to see if issue persists. I do know it's not my WiFi as my other devices have no trouble. But this is quite annoying.

Are you by chance using an Apple router or access point? For some reason, they don't seem to play well with Android devices, including my M8. I've had a similar experience with 4 Android devices and 2 different Apple routers. The devices continuously disconnect and reconnect.
No I'm using an Asus ac66. The funny thing is the connection doesn't drop. It always says connected. The data just stops flowing and then starts again. For example I'll run a speed test and the download will pause then start up again. Very odd. Never had a phone do this before

I've got an Apple Airport Extreme. I also have several Android devices. Have had many that I no long have or use. I've never had any problem with my wifi on any of them. I have to wonder if your problem isn't related to something else. Or, possibly your router needs to be replaced. Might be a matter of settings too. But, like I said, I've never had any problems with mine.
Within the "Advanced Wi-Fi" settings there is an auto-enabled option called "Wi-Fi Optimization" which minimizes battery usage when Wi-Fi is on. I assume this monitors for extended periods of inactivity (screen off, no active downloads, etc.) and temporarily disables/hibernates Wi-Fi activity.
I've kept this option enabled and haven't had any issues so far, but maybe you could try testing with/without this setting enabled? Another thing to try would be checking highly-used radio channels in your area with an application like InSSIDer and making sure your router is broadcasting on a low-use channel. I see no correlation with the radio channel and your new M8, but it's worth a try

I have the same issues. and ive turned off wifi optimizaiton, ive set my wifi control frequency to 149, ive tried to switch between 2.4 and 5ghz. i feel like my issue is with the phone not picking up the wifi signals very well... we live in a brick house, and the asus ac68u sits right in the middle of th house, and my room is only right around the corner. everyone elses phone picks up 5ghz or 2.4ghz frequency fine in my room, even my gf's M8 (we bought ours from verizon same time for the deal). i literally get wifi in my rom 10% of the time or its choppy and slow. so everytime im in my room i have to switch to cellular :|
Hello there,
I'm having a bit of a issue with my 3G connection; I'm getting a lot of different issues while using it inside of my house. The main problems I'm having are the following:
My connection keeps freezing; even with 3-4 bars in 3G coverage. It also happens randomly, it can work a while then stop working and then continue to do so. Sometimes I'm even barely able to use the 3G connection. Putting the phone in airplane mode, and then back "usually" solves it, but sometimes it happens every fifth minute so it's really annoying.
The phone keeps changing cell towers to other towers with poor 3G coverage (which pretty much kills my connection), even when it's connected to a 3G network with 3-4 bars it changes after a while to a network with 0-1 bars in coverage.
Sometimes while loading pages or when trying to download files they get corrupt due to the connection; I've got no idea why this is happening.
I've been in touch with my telecom provider before and they've told me that there's no issues with their celltowers in the area; they've even been there to check it and I'm the only one in the area who've reported the issue. I've tried to put the simcard in another phone, but still no luck.
Is there any way to resolve these issues? I've been thinking if there's any way to force the phone to stay on the same celltower, but I've not found anything regarding it as of now. Any ideas?
Bump. Anyone?
Hello, I recently bought a Pixel 5. I have a cabin in a remote area where we have DSL internet service. It worked GREAT 2 months ago when we had a certain modem (which type I can't quite remember). Anyway, one of our business guys had it switched with CenturyLink to a new Modem. The bandwidth in the area is admittedly weak with only 9-10 Mbps download, but that didn't seem to have an issue on my phones ability to access the internet in the past.
Anyway, this last trip I can find and log into the new wifi no problem, but I quickly get a "No Internet" message on my phone which persists for 99% of the day. On occassion I get a quick connection and get notifications of emails etc. but then it goes right back to "No Internet"...
Meanwhile all my friends have iPhones and other older smartphones and have no problems getting on the internet even though it isn't the fastest.
It must be a setting on this PIxel 5 that quickly gives up after identifying a slow speed of Wifi instead of letting me use what is available like those around me.
HOW CAN I CHANGE THE SETTINGS IN THE PHONE TO NOT BE SO DANG PICKY AND ARROGANT ABOUT THE BANDWIDTH IT NEEDS TO GIVE ME INTERENET ACCESS INSTEAD OF "NO INTERNET".
I'll pay for tech support!
