WiFi Shuts Down
Old HP laptop. Win XP Pro with all updates.
At startup and hot reboot the WiFi comes up and always shows the WiFi list but does not always automatically connect the "Automatic" (default) WiFi. Sometimes I just have to click connect and other times it automatically does the connect. Then after some time all WiFi-s vanish from the list and it says it cannot find a WiFi. If I reboot I get the list of WiFi-s back and can click on the one I use and make a connection. This is a hot reboot in that the laptop does not have power turned off on a restart or for only a second or so if I do a shutdown and turn it back on. Either way the WiFi list comes back and I can use it. So I do not think it is a temperature related problem. I have no other problems with the laptop. Now running MS Security Essentials and just previously Avast with no problems. Same WiFi problem with either. Any suggestions on what 1) to look for? 2) what to try? TIA |

Suggest you check your wifi's power management settings. I had a similar problem with a Thinkpad T61. Traced the problem to Lenovo's Think Vantage Power Management. Fix was: uninstall Think Vantage Power Management and use XP's, and set wifi not to turn off. Worked fine after that. Stef |

Stef You can also check Device Manager, and see if the power setting there allows the device to "go to sleep" or not. Do Properties on the Wifi adapter, and look for a tick box like this, and untick it. Just as a test. "Allow the computer to turn off this device to save power" Paul |

TIA I checked all suggested and found no problems. All WiFi access points, my router and the neighbor's vanished and I had a blank list. After playing with settings I found a "Repair" button and clicked it. I had the Network Connections open at the time and the not connected changed to connected and I had WiFi access points (including my router) and Internet access. But why does this need "Repair". Is there something corrupting the WiFi access that needs constant "Repair"? What can I look at now? Is there some place I can look to find out what was "repaired"? |

I couldn't find info on a log file specifically for the repair. The repair procedure is described here. I suspect the description isn't really complete.

These steps are shown below in the order that they are initiated: Broadcast DHCP Lease Renew Flush ARP cache [Address Resolution Protocol] Nbtstat –R [clears the NetBIOS name cache] Nbtstat -RR [re-registering the machines names with a WINS server] Flush DNS cache Register DNS name [re-registering... with a Dynamic DNS server] " Before trying a repair, you could run this. http://support.microsoft.com/kb/894568 "netsh ras set tra * ena [ Netsh ras set tracing * enabled ] [ probably as administrator, in cmd] Reproduce the problem netsh ras set tra * dis [ Netsh ras set tracing * disabled ] The logs will be at %windir%\tracing Wzctrace.log Eapol.log Rastls.log Wzcdlg.log Xmlprovi.log Netman.log Netshell.log " So that generates some logs. You could also try Event Viewer, and see if a log entry was dropped in there. That's all I could find so far. Paul |

Wait 15-20 seconds, turn on modem and router, boot. -- dadiOH ____________________________ Winters getting colder? Tired of the rat race? Taxes out of hand? Maybe just ready for a change?
