WHY DO I LOSE MY CONNECTION TO THE NET WITH MY CELL-C HUAWEI E1752 3G USB INTERNET STICK BEFORE MY ACTIVE DATA BUNDLE HAS DEPLETED?


If the device has worked for you in other locations, the most likely answer is that you have low signal strength from your network carrier to your device. To test if low signal strength is the problem, try moving your laptop to another location, closer to the cell tower you think might be servicing you to see if it starts working. If your laptop connect software has the ability to show you the signal strength, look to see how many dBm the signal strength is. The larger the negative number, the worse it it. Below -85 dBM, you will have frequent drop outs.
-75 to -80 dBm should give you usable results. -65 dBM and lower should give you very good results. If you can only find the strength in bars, 1 or 2 bars is bad, 3 bars marginal, 4 & 5 bars useful to good. You can buy repeater devices which pick up cell signals and rebroadcast them, making them stronger for you laptop to pick up the cell signal. They usually have an external antenna port which you can put outside and high to help pull in the signal. Trees, hills, and rain all block and lower the signal strength between you and the cell tower. Distance is also a big factor.

What does the red circle on the face of my Casio wv200a watch mean or signify?


This is the strength of the receiving signal for time calibration! The 3 sectors are to measure the strength of signal! 3 is max strength and 0 is no strength!

How to increase connectivity and strength of 2G and 3G network


@Surendra

It's based on dBM and asu and not the bars you actually see. Even if you may see fewer bars you could have equal quality. The phones, based on different OS may be calibrated a little differently. It's best to contact your service provider and verify....

1. Your SIM is properly programmed.
2. Your PRL is updated
3. You have a recent SIM

Are there firmware updates? My iPad is dropped from wireless intermittently.


im not really familiar with the ipad but my best guess is your wireless router signal strength is what is causing your ipad to drop. No firmware update is going to fix that. i would recommend downloading a wifi analizer from the app store to get a reading on your dbm (signal strength) from your router. the dbm scale will be 100 dbm(best) to -100dbm anything below like -50 dbm and you will start seeing disconnects.
I would either A. Invest in a wireless n standard router or buy a repeater to boost your signal.
Comment if you need additional assistance.

Try cutting the phone off for 5 minutes then back on. If that don't work you'll need to call the company to see if the tower is down or if they can reset the phone.

Connect my Lynksys WRT54G2 Router with my Belkin (F5D6231-4)


You can connect 2 routers to each other. But the IP address will be different for both the routers .
It will be better to keep different names for the wireless network.
If you keep the same name, then it doesn't mean that the signal strength will be good. Because both the routers will broadcast their own signals.
If you want to increase the signal strength then you can purchase a wireless range expander.

The range of a Bluetooth device depends on the Radio Class. I am not sure what the Class on a BlackBerry Curve is, but here are the options:

Class Maximum Permitted Power mW (dBm) Range (approximate)
Class 1 100 mW (20 dBm) ~100 meters
Class 2 2.5 mW (4 dBm) ~10 meters
Class 3 1 mW (0 dBm) ~1 meter
