it is normal, when i start my IDm download sometimes ping will shoot up to 200~500ms, it is very normal especially when u uploading file,
my example:
[attachmentid=3161653]
ping will raise :
- when your Download & upload speed either one or both running nearly @ max ( Max in your available connection from your area base station )
- when u upload huge big file
- when tower congested/super busy
- when weather is super bad affected the SNR ( sound and noise ratio ) measurement of your signal
just remember to limit any of your software upload speed, so your ping will be maintain low and Download speed will increase
before using panel antenna from blacktubi, ping even higher than what u see in screenshot, and now after using, ping consider much lower already during heavy Download session
Added on November 18, 2012, 3:19 amyou should place the usb fan blowing from either of the zte mf680 side, can remove the sim card cover, it will help,..
blowing from the side of external antenna hole or the microsd memory card slot, the wind will penetrate better compare to just blowing like in your photo
thank chuah for explanation about this...i did not realise it before...only 1 tower with 3G support...oh maxis...please laa upgrade
