crickt wireless broadband card strenth too weak and slow.

Get a better wireless card. A better antennae.

if a600 open cricket broadband and press ctrl+d password ##ftm*. that opens a hidden options menu ignore manual activation. goto settings.

there are several options in this menu that could help you.

If they have a USB dongle do this. Get a USB cable extender, and an aluminum pea strainer. Punch a hole in the back of the pea strainer and insert the USB dongle into it like a satellite dish. Connect the USB cable extension. This works with WIFI and should work fine with cricket. I don’t have cricket, but if the software has a signal strength meter you can move the pea strainer until you get the best signal. You also need to tweak the depth of the USB dongle in the “dish” to adjust the focal point. If the software does not have a strength meter, try some speed tests in different directions, that should be a good indication of your connection quality. AskHack.com
