[michael 123]

When I connect usb device to the second usb port of my computer ( from the left side) it don't work!
During the start ( from hibernation ) my phone shows me that it is connected to a usb device but when it had finshed starting my phone shows that it is not connected. Also my computer can't connect to my home wi-fi and it show that there are no available networks even that it had connected to it before and my phone is still connected. At my friend's house it shows that it can't connect to the network. My Bluetooth also don't work. Help pls.

L'chaim!

Do any of your USB ports work? If only some of them work, then you may have a bad USB port. An easy fix for this problem would be to connect a USB hub to one of the good USB ports, which would give you a few extra USB ports. (Be sure that you get a powered hub, that is, a hub which has its own power supply. Sometimes the power coming in over the USB line isn't sufficient.)

It is possible that your phone cable is defective, rather than the USB port. Have you tried connecting any other USB devices to the port in question?

If your cable is not an Apple-brand cable, then it probably won't work for data transfer. Apple-brand cables have a special chip in the plug. If this chip is not present, then the cable won't work for data transfer, although it can be used for recharging the phone.

As for the wifi issue, have you tried connecting with an Ethernet cable? Also, try reinstalling the driver for the wireless adapter. Do the same for the Bluetooth adapter.
