Thread summary and practical next steps based on the replies from , , and . The symptom (phone tethering to a Windows 7 laptop that drops after some time) can come from three places: phone-side idle/power rules, Windows power-management (USB/Wi‑Fi/Bluetooth), or a protocol/carrier timeout. Missing details that matter: phone make/model, tether method (USB, Bluetooth, Wi‑Fi hotspot) and whether the phone physically disconnects from the PC or only the internet session drops (as and hinted).

Concrete troubleshooting (apply one change at a time and retest):

  • Power plan and adapter power: Control Panel -> Power Options -> Change plan settings -> Change advanced power settings. Disable “USB selective suspend,” set Wireless Adapter Settings -> Power Saving Mode to Maximum Performance, and set PCI Express -> Link State Power Management to Off.

  • Device Manager: open USB Root Hub entries and the network/bluetooth adapter properties -> Power Management and uncheck “Allow the computer to turn off this device to save power.” Swap USB ports/cables and avoid hubs.

  • Drivers/firmware: update or reinstall phone-tether and laptop network drivers from the vendor. As suggested, driver faults can drop connections.

  • Dial-up/PPP style connections: if the tether appears as a dial-up/modem connection, inspect the connection’s Properties -> Options tab for any “hang up if idle” or idle-timeout setting and disable it.

  • Diagnostics: check Event Viewer (Windows Logs -> System) for disconnect entries and capture network state with commands:

    ipconfig /all
ping -t 8.8.8.8
netsh wlan show interfaces

Notes and cautions: disabling power saving increases battery use. Carrier or plan tethering limits can also cause drops; test with another phone or PC to isolate the side that’s failing.

What phone are you using?

I would inspect the driver for options re disconnecting.
Unless u r using a cell phone and the signal is weak enough to make it drop the call.

By disconnect you mean the phone from the computer (vs losing connection to internet), right?
If not could it be a fair usage policy thing?

If it is disconnecting from your computer, how and what is connected in the first place (is it a cell or land line, do you use cable or bluetooth for cell or if land line, is it a usb modem, an internal one...)
