3G Switching to HSDPA and back

[MrOoze]

K. This is what I came up with at lunch.

A simple little batch file as follows:

cd\
:start
ping -n 1 -l 1000 google.co.za
ping -n 2 127.0.0.1
goto start

What this does is send 1000 bytes to google (testing revealed that pinging at 940 bytes was sufficient to keep the HSDPA Link open). Then, purely to minimise bandwidth usage, I put in 2 pings to your local machine (This seems to be the most you can do before the HSDPA Link breaks from non-throughput)

These 3 pings run in an infinite loop - so remember to close the thing down, should you try it. I'm guessing the numbers may need to change for different people in different situations. If you're still switching to 3g, try removing the "ping -n 2 127.0.0.1" line. If you're still switching after that, try incrementally increasing the "1000". (1024 = 1kb)

My rough calculations put this batch's usage at around 3mb/hour. It could be a complete failure - I'm going to try gaming with it tonight, and will report back tomorrow.

Well, I tried my batch last night (if you know what I mean) and I must say, it worked a treat.

I played WoW and TF2 for a few hours and only saw 3G twice. Due in part to the fact that I had adjusted the "1000" down to "500" and upped the "-n 2" to "-n 3" (I did this to see how little bandwidth I could get away with using) Came out at an extra 1-2Mb/hour.

So I'm quite pleased. I would like to hear back from anyone else who was having this issue with Skyping to see if it helps there as well.

Hope there's no copyright on that there batch file - just tried it and it works well for skype texting which has been problematic for me out here in Australia.

But I still say:
"Notwithstanding the fact that I shouldn't have to ping or trick the system into giving adequate service."

Thanks MrOoze

No copyright.. but I do ask that every time anyone uses it, they tilt their head to the left, look up and think pleasant thoughts about me.

Glad I could be of some help.

Hi there,

Also going nuts with this switching of 3G and HSDPA. Been like this since beginning November, my phone does not survive a day with all the switching.

Also no calls calls be made or received (Tytn II) during this crazy switching.(Weird)

Eventually downgraded to EDGE connection level and have no problems now. Wife is also experiencing it with her S320.

Strange that MTN is so quite about this...

Hmmm, I'm up for trying anything, but am a bit of n00b when it comes to using the command prompt - anyone know how to run the batch infinitely? I manage to get it to run once, but that's it

Copy the text and paste in notepad, and save the file on your desktop. Make sure to save the file with .bat extension.

Double clicking the file pops up a command prompt window with the commands going in the loop.

yeah, for the record, what makes the text MrOoze wrote a loop is the go-to-start part, lol

cant wait to play tonight.

Awesome, thanks guys

 

[MrOoze]

Very glad to see this is helping other people too - it's been a lifesaver for me.

3G HSPDA Switching the answer... maybe

Ok I am sitting on the "inside" to this issue. I am going to chat to the 3g guys here (at MTN) and find out why this is happening and how we can put a stop to it. I believe that recently this was loaded on our sites to stop idle users taking up HSDPA throughput. But it's created a whole new set of issues. Let me see what I can come up with and maybe actually have a decent solution other than end users having to setup loops.

More info

for those of you still reading this thread and experiencing the problems mentioned in it, please can you post the area that you are getting these issues. Seems to be a radio problem and we are going to get people to investigate further. Please state the province and suburb. e.g. Gauteng, Sandton

Hi Slaphead.

AFAIK, it's all over. But I'm in Constantia Drive Roodepoort. This is affecting allot of online gamers also, might want to update the other thread in here and the WoW subsection.

Updating the firmware on my e220 to the huawei 7.2 mbps version improved things for me. (Vodacom, BTW). With the same firmware on the same modem, however, in Oz over xmas, I was still getting the switching thing from 3g to hsdpa and back all the time. ( I posted above). So I guessed it must be a network thing. VC seems to have fixed it - on my local tower at least anyway. E220 light stays cyan (HSDPA). What a pleasure.
