Intermittent wireless on a single desktop while other machines and a wired link work points to problems local to that PC or its adapter (driver/profile, power or USB/PCI hardware) or a mismatch with the router’s wireless security/settings. Common real-world causes are saved/incorrect wireless profiles, authentication/encryption mismatch, DHCP failing after a brief association, adapter power-saving, or chipset incompatibility with a particular router.

Recommended checklist (prioritize in this order):

  • Update the wireless adapter driver and, if available, the adapter’s firmware.
  • Remove the saved wireless profile for the SSID and reconnect from scratch to force a fresh handshake.
  • Disable adapter power saving: Device Manager → Network adapters → Properties → Power Management → uncheck “Allow the computer to turn off this device…” and set the OS power plan’s wireless adapter setting to Maximum Performance.
  • Force the router to a single, modern cipher (WPA2‑AES) and re-enter the passphrase after clearing profiles; avoid mixed TKIP/WPA modes which often break stability.
  • Temporarily assign a static IP in the router’s LAN range to rule out DHCP lease/timeout problems.
  • If the adapter is USB, try another USB port (rear ports) or a powered hub; if PCI, reseat in a different slot.
  • Change router channel to 1, 6 or 11 and set channel width to 20 MHz to reduce interference from nearby networks/phones.
  • If available, test with a different USB/PCI adapter or a spare AP to isolate hardware vs router.

Useful checks and commands (Windows): run ipconfig /all to confirm DHCP status, ipconfig /release then ipconfig /renew to test leasing, and ping -t <gateway> to observe drops; netsh wlan show interfaces reports signal and auth state.

Notes: ’s interference tip and ’s chipset-compatibility observation are both common and worth testing. Recreating the secured network or rekeying credentials often resolves stubborn auth/DHCP mismatches (as reported by ). If problems persist after the above, swapping the adapter is the fastest way to prove a hardware fault.

Hello,

I have seen this type of activity before when the wireless is getting interference from other devices or even the adapter it's self. If you have a cordless phone move it away from the computer having problems or unplug it and see if the problem goes away. The other thing is that the wireless signal is a very high frequency and if the system is close to the ground floor (cement foundation) it can cause interference with it's self by reflecting off the floor.

If the router is near by then use the wire instead of wireless. Wire max speed with good signal is 54Mb and wire is 100Mb and has no interference. Just a suggestion.

Have seen this type of problem before. My own laptop always has a hard time to connect and keep connected with the wireless router at work. At home no problems at all.
The reason is that the chips in the router and the onboard wireless card in the laptop doesn't seem to like each other. There are a lot of wireless cards that can connect without any problem with almost any router, but always have problems with routers of brand X or Y or Z.
Maybe if you search the internet for incompatibility between your router and wireless card....

reset the password on secured access with wired connection and after changing password , disconnected wired connection , connected with wireless connection - it got connected.
