MDA Vario stops transfering GPRS data after minutes

Hi everybody, I have some troubles with my new MDA Vario here in Austria:
When the devices goes online (through scheduled Active Sync or manually when browsing the internet) GPRS data will be transmitted only a few minutes, after that no data returns over the air to the phone. The device IS connected (the 2 little arrows are visible).
With some network monitors (Phatnet for example) I can see that the MDA is trying to send packets to the GPRS net but nothing ever returns. I have to disconnect the GPRS transmission and reconnect, sometimes twice or 3 times before data flow starts again...
What's up here? Network signal quality is ok, I don't believe it's on the providers side (A1) because moving the Sim card in an older mobile does deliver error free GPRS connections for hours.
I have found a similar problem here : http://forum.xda-developers.com/viewtopic.php?t=32936
But my problem is not dependend on my phone usage...
Has anybody else seen this occuring?

some additional information
Hi, did some additional research: This problem seems to be a provider issue, does anyone in Austria have the same problem with A1?
If that really is a provider problem, MSFP will never work... I hear a lot of cries right now... The data connection is stable from a few minutes to a max. of about 30 hours

GPRS / EDGE - always "connected"?

I am using GPRS/ EDGE. Sometimes when I have NOT used any Internet program, the G or E icon become a pure square G or E only without the 2 arrows. Does it mean it has DISCONNTED the GPRS/EDGE? Now if I launch IE and click a URL, the E/G icon will flashing with a moving 2 arrows and eventually after 1 or 2 seconds, become a "square E/G icon with fixed 2 arrows".
I am wondering, shouldn't the GPRS/EDGE be ALWAYS connected, such that the "G/E icon with fixed 2 arrows" should always appear? What setting I should change in order to make my Xda neo perform that way?

Hi isomania!
1) The icons are interpreted as follows:
Solid G/E - GRPS / EDGE network present, but not connected.
Small G/E with moving arrows - connecting to network.
Small G/E with solid arrows - connected.
2) There is no point to keep GPRS\EDGE connected when no programs are using it, since that would only shorten battery life. If I am not mistaken the timeout on the connection cannot be changed from the device side. I know push mail function sends some data (I think 400 bytes every 120 sec) to keep the connection alive, but it kills the battery and racks up the phone bill (unless you have unlimited data).

Thanks for your explanation. But for me, "connecting GPRS/EDGE" is STILL costing some time (may be 1 to 2 seconds). so i am wondering if I can keep GPRS/EDGE connected all the time I want, so that whenever I want to check POP3 email / go to any website, then I don't need to wait the 1 to 2 seconds connection time. Now THAT'S would be my definition of "always on"

One or two seconds to establish a connection? How will you ever manage having to wait that long? :roll:

Check the various tweaks n tips floating about, there's always a couple that will force gprs to remain on at all times. The downside isn't battery life, it barely affects that or push mail wouldn't exist. It's that eventually you will lose the signal, the connection will die and you won't notice the difference until you try to use it. Then you have to either toggle flight mode or reset the phone...after you figure out what happened. If you're constantly having to connect to gprs, you may be better served by looking for a disconnect timeout. With that, it'll get the occasional chance to reset the connection, making sure it's active. I have no idea what they are offhand and don't use them but I've come across them in the past so try a search and check the wiki.

Sorry, but I have to disagree.
Maybe if you manage to somehow keep the connection without transmitting anything (not sure this is possible) the battery drain will be minimal.
I am using push mail on my Jamin for only 3 days and the difference in battery drain is very noticeable. In fact even with no mail (I don't sync the rest) to transfer the battery life is cut almost in half.
I read an article where the same is reported for the universal.

i have a question about this related topic, i'm a noob, just got my mda on wed and i called them and added the data plan to my existing line, the guy said it would take about 72 hours for the browser to be surfing the web normally, well today is sunday and i still can't surf, my G icon on top is with arrows moving, and it shows i'm connected to EDGE but my browser only says Locating and never loads anything, please help?

Hi werkmeister47!
Arrows moving means GPRS is trying to connect, but not actually connected.
There are two possibilities:
1) The provider hasn't connected you yet (72 hours??? When I bought a SIM from Orange I was surfing in 5 minutes)
2) Your connection settings are incorrect. You have to contact technical support for exact settings for your network.
Good luck.

Wi-Fi Won't Turn On most of the time

My HTC HD has WIFI Problem: WiFi will not turn on most of the time.
After tapping the Wi-Fi Switch (in Communications Tab) it hangs for about 7 seconds then stops.
Sometimes after 6 seconds the wifi Icon will appear for 1/2 a second but then disappears.
The only way I can get it to connect at all is if the device is cool and I remove the battery for a while....
...Then restart it and Wi-Fi will switch on sometimes (but fail most of the time).
I have flashed the ROM (by different Cookers) many times, Hard Reset the device many times, and used all different power settings: Still no good.
If error reporting is ON I get error message "device.exe' problem.
As I live in Australia I would have to pay heaps for freight if I send it back to UK so I'm loath to do so.
Anybody know what should I do to fix it?
(PS. My old Diamond connects every time)

I have a similar WiFi connectivity problem, but after reading of the poor service provided by most vendors and HTC itself, I will try to gather some more experience with the problem before I contact HTC or my vendor, and hopefully find a solution. Bellow is my experience so far:
I own an HTC Touch HD since January and have a similar problem, only it surfaced last week. Before I had only used the WiFi connectivity briefly. The problems started after I installed an AP on my house expressively for the new PDA. The node is fully open and set to B/G/N protocols.
After a couple days of medium (couple hours per day) use the WiFi connection suddenly quit, the device would try to connect (the top bar showing the WiFi connection animation continuously) and after a few moments gave up with a dialog box stating the current network settings were wrong (even thou they worked fine a few hours earlier).
I tried several hot and cold resets, but only solved the problem after flashing a new ROM; even then the same symptoms reappeared after a couple of days of regular use. Again no re-setting would cure the problem, and now not even flashing the ROM again would work. Nonetheless, some hours latter the WiFi would connect perfectly with the same nodes it refused to before, and in very short time.
I have witnessed this cycle twice and have yet not been able to find a trigger for it, but will keep my eyes open for any tell tale signs, and post any findings here.

What I found out is that If you are using CommManager in TF3D together with other wifi mgr it screws up the wifi. Either you use CommManager or you use 3rd party one but not both at the same time.

Agreed!
Yes I agree completely; something on the permanent storage area got corrupted last week after I installed WiFi Monster (which I like, and recommend, only not at the same time as the standard connection manager).
I managed to get the WiFi conection working again (if only for a couple of days...) by doing the Start>Settings>Clear Storage thing and following the re-install.
Ok, so at least now I know of one more thing that can screw up th HD's WiFi besides itself!

i cant connect to my wifi in my same bedroom !!!

Enhancing WiFi performance
If you get very low range, or frequent connection interruptions, it might help to go to: Settings>Connections>Wi-Fi>Advanced>Power Mode and set it to "Best Performance"
PS. I wonder if anybody gets intermittent WiFi problems like myself. One day it works perfectly, the next it will not connect showing a dialog box: "Warning Cannot connect to the network. Check your network and service provider settings and try again"

time to connect is getting bigger amnd bigger

Resently I noticed that the time needed to connect to a remote server is getting bigger and bigger. I made an application that measures the time from sending a request to and getting a response from the server.
About 6 months ago I made a hard reset. At that time the server response took only 12 seconds, after 4 months it was 40 seconds. One month ago it was 55 seconds and now it is 65 seconds. I connect via gprs or 3G+, in both cases same result. I alwas use the same application that connects to the server.
The same situation is if I want to see www pages. No matter if I use IE or Opera browser and switch between http or socket connection. When I type the url address and click connect, approx. the first 50 seconds - nothing is happening, then an indication of data connection pops up at the top and the page is opening. After that when I connect to any different url address, the page opens very quickly.
I tried to delete cookies, temp files but with no effect. Something is apparently growing up in my device but don't know what. The time to connect for the first time is getting longer and longer/
My device is Acer DX900 with WM6.5.
I don't want to make a hard reset again. All advices are wellcome.

A300FU WiFi locks entire Router

OK - I use LOS 14 which has been more or less fine ( a few documented niggles on the thread, but OK up to now)
About two weeks ago, without any obvious changes my WiFi locks the entire router - resulting in a router reset. Router is a "TP Linke AC750 Wireless Dual Band Gigabit Router"
I did initially think this was triggered by the IP lease expiry, but set IP addresses or maxing out the lease time didn't seem to work. But it does seem to occur when the phone reconnects
I have increased the log settings - see screen shot - with "network_selection_disabled_association_rejection=3"
Also, in the Logs there is WiFiQualifiedNetowrkSelector: <ssid>: <mac of router> is on blacklist
Looking around the net this error seems to be down to the phone blacklisting the router due to poor connections - but I didn't even leave the house today and it hit
I've tried lots of tweaks to WiFi, keeping it on, keeping it off. I have now just moved my Routers channel to a less busy one - but I have no idea what is causing it.
I have removed all the apps that I can recall installing just before this happened.
ROM is as it is and was stable for months before this happened - Router firmware is up to date and went through factory reset - can't do that for phone for a week as it is my key generator for 2 factor authentication to work network and if I zap phone you can bet work will need remote access before next week!
Ideas anyone?
Cheers
