WIFI always disconnects, and reports "no internet access". It might connect back after some time. It happens in many different locations: at home, in coffee shops etc. My colleague told me that it might be a problem with WIFI adapter in my laptop. It might be loosely connected and overheating. Or might require replacement. Before I go that way I wanted to get second opinion. Thanks.

Right after I lost internet connection I got the following from the Chrome Diagnostics:

Windows Troubleshooting

"The default gateway is not available."

I have the following adapter

Intel(R) Centrino(R) Wireless N-2230

Router

AirPort Extreme 802.11n

EDIT 1: - OS: Windows 8.1 - other devices usually stay connected to wifi router at the time when my laptop drops the connection. - It looks like it depends on how much data I send to the web. For example, If I work with the cloud, and it often then the connection might drop every 5-10 minutes. - The signal is usually good, when it reports "No Internet Access"

  • Might want to try a >netsh winsock reset for good measure before you spend money on a new adapter. Feb 10, 2015 at 0:12
  • I did just that and restarted my laptop. Is there any definitive test for adapter to confirm that it is defective ?

If it drops connection frequently and/or it doesn't matter how strong is the signal, then it's the adapter. Recommend replacement.

  • With some other connections it has stable connectivity. Can it be some frequency mismatch issue ? Or, timeout issue ?

  • Edit your query as you just provided new and question-contradictory information. What other connections? Include also how often connection drops, how far was it from AP and/or what singal strength was at the moment? Do any other devices have same issue? OS installed on laptop?
