VERY WEEK NETWORK IMEAN SIGNAL VERY LOW

Hi if your siemens A57 mobile is locked to network provider .Then you can easily unlock it using network unlock code .You can purchase code from sites like ClassicUnlocking.com they are rendering unlock code for all mobile models at reliable cost .You first verify that whether the code is available for your country and network provider .If yes then pay for it and unlock your phone .

call your service provider and ask them to provide internet settings for conecting to pc.while you got it apply those settings as default and then try connecting.
good luck

i'm trying the activesync fix.

Firstly try the Off Line option, sometimes this can be ticked. Or go into the Netword Card settings and try to force the speed to auto config, this will enable different speed connections

i think it is hardware issue need some parts to replace or try to Update or format ur device

Use Restore CD's or what method they provide.
