[super noob] Extremely unstable data connection (phone issue, with linux on pc) - 8525, TyTN, MDA Vario II, JasJam Software Upgradin

Hi there,
i'm very noob to pdas in general, i have this herm100 that my friend sold me when i needed to get internet access (i combined my budget for phone and internet in one).
Well, after a while of hard work, i was able to get data working on my Linux PC (EeePC 701). The connection was closing automatically when not in use, this behavior is useful when not used as modem (to keep battery).
I created a script that "connects" my pc to the phone (it setups the interface's ip, etc...), when connected, it then pings the phone (10.0.0.1) and pings my host on the internet by IP (this tests that i have access to the internet). It makes other tests too to make sure dns is working and that my webserver on that host is still working too...
I make the pings to the host by ip every 15 seconds (or less when it fails). With this and minimal internet usage, the connection will drop on the phone 2 to 5 times a day.
When i say that the connection drops, i mean that ping to the phone works, but ping to the internet fails, times out. Most the time, the internet sharing prog on wm6 says it's still connected. Many times, if i try to access the web from the phone it will fail (wait forever, rarely will also freeze). So when the internet is dropped, one time out of 4 i have to reset the device (i found that shutting down for a while gives even better results).
I just recently got a super promo for my data package with my isp and my limit got increased a lot... I tried downloading torrents. Downloading torrents will cause the phone to drop connection _at_least_ every 5 minutes!!! The device is also pretty hot (like i wouldnt like to have that heat in my jeans pocket but doesnt hurt when touching). I have setup my torrent application to limit download and upload speed so that overall no more than 15 KB/sec is used and this increases stability a lot, but it will still fail within 10-20 minutes.
I wonder if the hardware could be responsible, but i'm clearly sure that the OS is the one most responsible (it fails to detect the network is down and fails to at least try to bring it back). Maybe an os upgrade or hard reset would help. But if i have to go that far i might just try to install linux on it instead (openmoko probably,unless you suggest anything else?)
I was wondering if you guys could help stabilize my connection a bit?
Thanks!

[Q] Internet connection problem (WIFI)

Hi all,
I got problem with internet connection on my HD2 (ROM 1.48). There are 2 ways I connect to the internet - WIFI and GPRS. GPRS connection works fine - I can download and read e-mails, make backups with MyPhone, update weather information, etc. But when I connect to the internet with WIFI, there are only 2 things I can do. I can browse web pages with Opera and update Twitter messages. But I can´t download e-mails, make backups, update weather information, etc. When I try to update or backup something, there is connection error (through that connection between phone and router is fine and web pages are running).
It seems to me like most of applications want to connect to internet via GPRS only. Is there any way to set up (or check) the phone to connect to the internet via WIFI when it is turned on?
Thanks for any advice
Sorry cant help but agree - it would be fantastic if there was some way of knowing / controlling when it used GPRS data and when it uses wifi. When wifi availabe obviously would rather use that than be charge a small firtune for data.
Any one out there about to help with this??
Internet browsing
Ditto. I can - after HUGE effort - connect WiFi but I cannot browse the internet using either Opera or IE. 2 year old Nokia connected and browsed literally within 2 secs! Also, the phone keeps connecting via GPRS all the time even with data connections off. Can anyone help? Thanks PS I know it's unproductive & forgive me, but I have to get this off my chest: this is the worst cellphone I've ever owned. Bluetooth doesn't work, internet doesn't work, handsfree car kit doesn't work. Does anything work?

correction, YOUR Bluetooth doesn't work, YOUR internet doesn't work, YOUR handsfree car kit doesn't work.
Get it exchanged. (if they genuinely dont work)
@others, go to settings menu all settings connection connections advanced select networks.
there are two dropdowns, in teh top one should be the name of your mobile data, , this is what automatic progs will use to connect to the web, in teh bottom one it should be 'the internet' (or sometimes 'my work network'), meaning they use wifi if available, and data if not.
(At least thats how they should work....)
If you set the top one the same as teh bottom one, nothing should try to use mobile unless wifi is not connected.
Could be a proxy problem? some operators set up a proxy, which can screw with connections.
samsamuel: Thank you for your advice. I´ve tried it - in both dropdowns I got "my work network", but no success.
I´ve found something interessting. When I turn on YouTube client (using WIFI), I can´t play videos. That should be ok when I got problem with internet connection. But YouTube client shows on the welcome screen preview of today´s added videos. So the question is why should application download preview of video, but it can´t play the video? I´m a little bit confused
Thanks for the suggestion, but I had tried that already and it did not work. I don't think it is just my cellphone. There are many comments re the HD2 that make it clear that it does not work with a Parrot handsfree carkit, Motorola S9 headset etc, and the 2 earlier posts reveal problems using WiFi too. It seems to be problematic on many fronts. I cannot even connect it using Windows Mobile via an USB port! And while I appreciate all suggestions it seems to me that this model is a (very expensive) lemon and frustrates huge numbers of owners. I find it odd that a 2 year old Nokia N95 can connect and browse instantly and a 'smart phone' doesn't work at all. I find it to be very gimmicky. I don't need twitter, facebook etc. I need voice dial, good PC software (like Ovi and PC suite) and bluetooth that works etc. The HD2 has none of this, but great graphics of a windscreen wiper, exactly the sort of pointless gimmick that reveals that the designers were interested in making a toy and not a useful phone.
I suggest you try and install "HTC_Wi-Fi_onDemand_by_Krocher". This program will always use wifi when available and stop the GPRS from connecting and will also keep your wifi on a stand-by. Please do read through the thread as you have to make sure that no programs using wifi are activated when you want it to be off. For me it solved several problems with wifi.
Second thought is to upgrade to one of the much more stable and already tweaked OS's. There are quite a lot out and you'll find everything about that on this forum as well.
Last thought, if it does not work it must be something to do with either the settings or the OS version as for others it works absolutely fine. These are complicated phones that, much like computers, must be set and tweaked to the correct settings in order to get the best out of them. If you just want a "buy and run" phone this is not the one.
Success,
Itamar

[Q] USB Tethering dies off in several minutes

So judging by the quick search, many people have this problem on many different phones, and no solution was found.
I know I've had this problem with my old SGS 1, and even Nexus One.
Same problem on my SGS II, tethering to many different desktops and laptops.
So it seems to be android-specific, or Windows specific problem, really.
Basically, when you tether with USB, first several minutes all is well and speed is good, but in about 5-10 minutes, traffic from the phone just stops.
Phone still shows tethering ON, PC still thinks it's connected, but nothing loads, it doesn't disconnect, it just drops to speed or 0 kbps.
The only way to restore it is to disable tether and reconnect.
Anybody has any idea why would this occur and how to prevent it?
Does it say no internet connection on the network indicator on the bottom right of the notification center? My guess is your carrier has an issue with tethering. I see your on AT&T. Do they have a plan that is specifically for tethering?

No internet connectivity loss is indicated in windows, it still thinks it has a good internet connection. I'm assuming that after a while, it will detect that although there's a connection, there's no actual traffic flowing through it, and will say that there's an issue... but for a long time, it's simply as if I'm connected, but actual speed is at 0kbps.
Browser tries to load pages and times out in 10-30 seconds.
Unfortunately (or fortunately) this definitely doesn't have anything to do with AT&T. I have unlimited grandfathered plan with AT&T and a custom rom, AT&T has no idea that I'm tethering. Internet on the phone is still working fine.
I kinda feels as if the usb tether drivers in windows (RDIS or whatever it's called) simply gives up after a while. Or maybe it's the android tether process that "forgets" what it's supposed to be doing.
you are running a stock ROM right?

Nope, latest CheckROM.
But as I've said, I had same problem with Captivate and other ROMs on SGS2 =(
i haven't found a custom rom where tethering fully works....thats why i went back to stock
Have the same problem on BOTH my Huawei ideos U8150 and my HTC sensation.
My wirelessly tethered devices still work flawlessly but my USB tethered desktop disconnects after a few minutes. Screen time out set to Max in case something in the phone went to sleep but no difference. Definitely not a network problem as my operator confirmed but an android (or windows problem) .
I even set USB Port power settings to always stay awake.
Hope we can find a solution to this.
Sent from my HTC Sensation Z710e
i got the same problem under ICS. tried on stock ZSLPE and custom XXLPQ firmwares. both do not work!
my stock gingerbread was able to work flawlessly without disconnection problem on the same pc. wtf is happening?!
I have Samsung Galaxy S Plus.
I am facing exactly the same problem.
Have tried different ROM's around 5, 3 were custom ROM's.
Looks like Android OS issue.

I had this problem on both my Samsung Charge(Stock app 2.3.6), and my Motorola Razr(Stock app 4.0.4). I believe it is a driver issue inside windows. It seems less of a problem on the Motorola phone as I get a few hours of USB tether before it exhibits the same problem whereas the charge started after a couple of minutes. ie. Phone has data and can access web, computer thinks its connected to the web and okay, but any attempts to connect to the internet from the pc fails.
The wireless tether works fine and does not exhibit the same issues so I would suggest you use wifi tether. I don't know if wifi tether uses more or less power than usb tether (assuming your phone is connected to computer and charging). If I get some more free time in the next few weeks I might try and do an analysis.

I've had this problems with pretty much every Samsung phone I had.
I have HTC One X now, and it doesn't have this problem. So something with Samsung drivers, I think.
Cool fact - HTC even has a one-click reverse tethering. So cool.
I have the same problem, but can't find out, where (windows or android) is it.
What I have:
Motorola Atrix (rooted with SuperOneClick, stock ROM)
PC with Windows XP x64 without WIFI
The only RNDIS drivers I could find was HTC RNDIS (for XPx64)
Situation:
I'm living in hostel for one month, and there is only WIFI internet here, so I tried to get my phone WIFI to tether into USB
What have I done:
Connected to WIFI over phone.
Turned USB tethering ON.
By default WIFI is not tethered to USB, so I found that turning USB tethering ON creates usb1 network and WIFI is eth0. Then I configured NAT by iptables on my phone to accept and forward connection from PC (usb1) to WIFI (eth0). [usb0 on Atrix is for Motorola Portal, didn't try yet to connect to internet throught portal connection, not USB tethering]
The problem in short:
At the begining everything works fine. But when many connection threads are opened (didn't look for that many count) connection stops. As it was already mensioned, PC thinks it is connected, on phone USB tethering is still ON, even more - ifconfig still shows the connection. The only diffrenece is that "ping 192.168.42.129 -t" on PC (192.168.42.129 is usb1 IP on phone) starts showing "Request timed out" messages. On the other side - from my phone, I cannot ping my PC either. So connection is like broken, no traffic can be passed, but both sides sees they are ON.
After turning off USB tethering, PC sees connection is off immediately and the Local Area Connection #23 is gone. After turning on USB tethering everything comes back to the beginning.
Current workaround (for me):
I am using VPS service, so I open dynamic SSH tunnel over putty, and use it as my SOCKS5 proxy. The worst thing is that not all programs can use proxies, and when I use such program it tries to crash my connection.
Sorry for my english, it is foreign language for me, if anything is not understandable or you need more test from me, please ask, I will try to do my best.

Hi,
I had the same problem with my Android Phone - P999 running Cyanogenmod 7.2
I had to go into usb debugging screen to adjust the Display power Settings to - Always ON when Charging - Option.
There is probably some power setting in your device that allows you to do that as well.
Basically Power Saving (Screen Off) Powers OFF the Tether.
Ensuring the Screen is ON while Charging (it charges while plugged into a usb port) ensures the Tether stays ON ALL the TIME!
Hope this helps you.
Took me quite awhile of messing around to find the right option.
I do have a similar problem but it's not time-dependant.
Phone:
Nexus 4 mako
AOKP JB-MR1 Build 6
franco kernel 3.4.0 build #121
Situation:
I use FolderSync to backup my sdcard to my Windows 7 FTP server. The reason for doing this over USB Tether is that I get speeds at around 14MB/s instead of 1,2MB/s over WiFi.
I noticed that it doesn't really matter how long tether is connected and nothing really happens as long as FolderSync is scanning the folders on the ftp server at low bandwidth. However once a larger file is transferred the connection is almost sure to break and show the symptoms described by the other posters (interface still up, just no packets being received at either end).
So I assume that some driver (either on Android or Windows) chokes on certain packets and then just dies. Anyone got an Idea how to tell which device causes the problem to investigate further?
I also noticed that if I had ADB enabled before starting USB Tether that the tether connection on the android will be disabled once the failure occurs.
I have problem with my realme c2 when i connect it to pc via usb tethering, it connects it running ok. if i make screen on by playing youtube or any video on it run but as soon as screen sleep it disconnect after some time
I'm a bit late to this, but for anyone else still having this problem:
in Developer options of my phone(Redmi note 11) under Networking, there is an option called "Always keep mobile data on". Turning this on should fix the issue
@Denav
This doesn't work for me. I have a Moto G Power 2021 and that option is already checked.

Were you able to figure out the issue? I'm having trouble as well. Mine disconnects after a certain time period and the times seems to be random. I've played around with the dev options and other cables and still having same issue. It seems to happen with mac and windows laptops.

CRC/MD5 Sum errors

I've tried to download the latest firmware for optus but every time I do I get an error with md5/crc
First was from an external site and 2nd from Check fus.
How do I fix this??
Keep trying. If you're using your phone, don't. Use a PC. If you're using PC & have a firewall or any IP blocking software, disable it. Try a different internet connection.
At some point one or more of the files are becoming corrupt/damaged.
These are the things I've tried whenever this has happened to me. This kind of thing tends to happen a bit with mobile broadband, tho it does happen on cable/DSL connections sometimes.
Using laptop. (wired connection ofcourse)
The router is shared with two other computers, so do you think if I only use it for downloading the firmware it will work?
Really pissed atm, takes so long to download too.
First time I tried to root my phone I borked it, so had to download stock to fix it. Just wouldn't work from home, every download ended up corrupt. So I went to a net cafe the next day & got it.
Nowadays, I find it only tends to happen if I forget to turn firewall & IP blocker off, but it's definitely a network issue if keeps happening. Definitely try the tricks I mentioned & do it without anything else using the connection at the same time.
Sweet. I'll try it tomorrow and see how it goes. Hopefully I don't have to end up going to internet cafe haha

Transfering data to a phone via SSH or Samba slow and often fails

I've fought and fought with transferring data to and from the phone, now I have an SD card, at least in my current phone, and only real way to move data is to yank the SD card copy and replace. Now for small files (say pictures) I've gotten ssh or samba clients/servers to work well, but only for small data sets. Any large file (A movie, over say 400megs) fails no chance of success, a ROM image at 250meg works 1 in 3 times.
I've fought this battle for years with an SIII (that was decent as at least I did not need to pull cards as they were un-mounted when you plugged into the computer), but remote transfers were a mess. My S4 never worked well, nor has my Note3, Nexus 5's or my current Note4. MTP is a nearly useless protocol (on Linux it is even worse than useless) and pulling the SD card is a hack. Now the network connection is not bad as I have 0% packet loss and I can download the same movie via HTTP from a local server, but that is also not always practical, since it requires getting the phone and moving the file to a location where the http server can locate it extra steps.
What I want is to have the Phone auto start a server (be that samba or ssh) when connected to my home network and then allow for transferring data (real data of any size). It is the transferring that is my issue, the autostart is simple with Tasker and works well enough. I've tried many different ssh and samba Android servers without much difference, and also different networks.
I also want to mention that downloading a movie to the phone is about 12 to 15 megs a second, yet to upload using ssh or samba is about 1.2 megs a second or 1/10th the speed, it should be at least 8/10th the speed. I assume the failures have something to do with Android interrupting the server communications as a notebook on the same network running Linux never fails. Cloud drivers are slow and impractical (however do work in a pinch) as it is also multiple steps and requires me to move data to a remote location I do not control.
My question is how have other people handled this issue with Android?
Thanks,
ERIC

Weird WiFi Problem Not opening Pages

Hey guys. So my Mate 20 Pro has the WEIRDEST issues. When connected to wifi a few web pages etc are not opening. Instagram can't refresh feed etc. But if I use my Mobile Connection or use a Proxy when connected to the wifi everything works. The same wifi connection on the pc works flawlessly. Opens every single page immediately including the ones not opening on the phone, and even plays games effortlessly.
What do you think is holding back this connection on my phone?
Sounds like you were using public WiFi and some tend to use a firewalls which block lots of different things, I was on the train the other day and they didn't allow forums
The wi-fi on my phone has been screwed since day one. It still 'works' for most things, like games and such, but web pages or links in a reddit app will mostly load (the progress bar will speed along and then grind to a halt) and then... Nothing. When I googled around, it seems like Huawei devices in general are known for this - a smattering of people have devices that are simply broken on wi-fi. Now, I haven't done extensive testing, so it may be the wi-fi devices in combination with the phone that are the problem. It isn't like I have tested this with all kinds of types of routers/bands. It certainly is strange, normally when a wi-fi signal is pooched you simply 404 or stop dead. The way my phone 'almost' loads sites makes it feel like an error checksum protocol spiraling out of control, choking the connection.
If I didn't have a lot of data with my plan, I would have attempted to return my phone.
