Hi there,
My friend just formatted his pc in office and installed windows 8 32 bit. He had a samsung mobile phone with 2G/3G internet. He is using internet from the mobile through his laptop with usb cable in his home. So the phone part is ok. But he is unable to connect the same mobile phone internet in his newly formatted office pc. His connction provider is Idea(India). He don't know how to fix this. So he told me to help. But i can't say anything by phone without knowing what is happening in his pc. I need help.Thanks in advance.

Short, practical checklist that follows and ’s driver suggestion. When a phone successfully provides Internet on one computer but not another over USB, the problem is almost always either (a) the phone is not presenting itself as a network interface (USB mode/tethering off) or (b) Windows lacks the correct RNDIS/tethering driver. The steps below focus on verifying both sides and installing the right driver for a Windows 8 system.

  1. On the PC: connect the phone, open Device Manager (Win+X -> Device Manager). Look under "Network adapters" or "Other devices" for an unknown entry. Right‑click -> Update driver -> Browse my computer -> Let me pick -> if available choose "Remote NDIS based Internet Sharing Device". If that option is missing, install the phone-maker’s official USB/tethering driver (match the OS architecture — 32‑bit vs 64‑bit). Prefer the manufacturer or Windows Update; avoid unsigned third‑party drivers.

  2. On the phone: confirm mobile data is active, use a known good USB cable and select the tethering/USB‑modem mode (Android: Settings -> More -> Tethering & portable hotspot -> USB tethering; iPhone: Personal Hotspot + accept Trust). If the phone is stuck in “MTP/charging” it won’t expose the RNDIS interface.

  3. Network checks: open Control Panel -> Network and Sharing Center -> Change adapter settings and confirm the new adapter is Enabled. If the adapter shows “Limited”, ensure IPv4 is set to obtain IP automatically and temporarily disable firewall/proxy to test. Small commands that help diagnosis: ipconfig /release and ipconfig /renew.

Quick extras: try another USB port/cable, reboot both devices, uninstall the tether device in Device Manager and reconnect, and compare behaviour with the laptop that works to isolate PC vs phone. Most cases are resolved by enabling USB tethering on the phone and installing the correct OEM RNDIS/tether driver.

And how do you expect us to troube shoot his PC?

But my first guess would be broken/missing drivers.

As Anima had said. This sounds like a problem with drivers. You will need to check with the phone's manufacture to see if they have/support Windows 8 drivers.
