      Windows 7 / Dell Vostro laptop / Intel Proset Wifi

      Following a recent MS Update I had a problem with the wifi hanging on start, with a revolving blue circle over the Wifi Systray icon.  I got so fed up I rolled back to a previous backup and the problem went away – for a long time – with just the very occasional wifi hang, of no consequence, I thought….   Problem has subsequently returned in full battle dress, my not having done any Windoze Updates.  Turn the machine on, everything(-ish) starts, and *randomly* the wifi may or may not start.

      If Wifi does not start I cannot then start the Services inspector to see what tasks are starting/started etc, since it simply won’t start up itself.  I can still use other bits of the machine – Word, Excel, Process Explorer; it can be a bit slow.  If I then “Restart” (rather than shutdown >> start up) the machine, it comes back up ok and the Wifi starts straight away and all is fine from then, until the next time I turn the machine off.  It’s either a turn off/turn on sequence or an alternating booting flag or some such, and possibly “Restart” temporarily cures the problem.

      I now don’t think it’s any windows updates causing this, since I haven’t done any.  It seems to me it must be something else that has updated since my rollback.  I have updated Firefox, but that seems an unlikely culprit as it is an application not a system program, and anyway I don’t have it on autostart.  The other thing I am suspcious of is the Avast antivirus where I do think I have updated the engine (still looking for logs to confirm when). I have heard that there have been recent clashes between AVs and MS Updates, though not any due to AVs themselves.

      I have taken to turning the AV off before shutting down, and so far the wifi has not hung on boot, but I have not accumulated sufficient data sets yet to say it was or was not the cause, due to the randomness of the problem.

      So I thought I would post here anyway, with the following questions:

      • anyone seen this?
      • any way of debugging this – are there wifi system logs anywhere?
      • any other suggestions?

      Thanks in advance

      When the wifi is running check for bad packets. This may indicate a hardware problem.
      How to.

      cheers, Paul

        Paul, thanks, yes I am getting a higher than 0.1 packet loss. Whether this is the machine or the very dodgy rural ADSL we’re on I will have to look further.

        Cesar, thanks, will check.

        Re this and the other, I don’t really see why either of these woudl lead to a change in behaviour.  So far the Avast shutdown before machien shutdown seems to be working.  Having just said that of course….  [/sods law]

      Turning Avast off before shutdown seemed to work for a while.  Then had a recent Avast engine update and have tried not turning it off, and so far looks to be starting the wifi OK on boot-up.  He said, tempting fate…

      Thanks. Having had no startup hangs after stopping Avast before shutdown, I then had done the most recent Win 7 Avast update and reverted to not stopping Avast before shutdown.  All went well for about a week, then yesterday it hung again (it’s that random).  I will recheck the latest Avast update in a W7 context. Incidentally, down that link, there are problems installing the latest Avast + 1903.

      Update.  Updated Avast engine. No change.  Still re-starts fine if you shut down Avast before shuttign down the machine.  If you don’t shut down Avast first, there’s about a 40% chance of a hang on re-start.  I think it’s time to take it up with Avast…

        On my Win7 computers, it takes longer to establish any network or wifi connections on cold boots, in comparison to warm reboots.

        When your issue occurs again, try simply logging off and then logging back on. This also is the quick fix for whenever Windows Explorer crashes, rather than rebooting the computer.

        Have you tried checking the Avast forum for similar problems? If this is happening with other computers maybe a solution exists there, support was good there and may still be good for users.

          Yes I have, thanks, but have not really got any clear answer as to why. The Woody site reports of multiple AVs having trouble with network connectivity is the closest I’ve got, hence my experiment (successful) with trying stopping Avast.  I may try a full uninstall and thorough purge of Avast followed by a reinstall.

      Good idea, I’ll try that next time I forget to stop Avast first and it hangs

      A note about a seemingly unrelated issue…

      I have been testing anti-ransomware. First, I tested ZoneAlarm’s Anti-Ransomware. It works, yet it does create honeypot folders which can grow in size over time. Next, I tested Cybersight’s Ransomstopper. It also works, yet one of its low level drivers occasionally crashes with a BSOD on boot.

      The upshot is that Microsoft has been messing with the Win7 kernel since around August 2017.

      Final word.  It settled down to starting OK, this was some time after the last Avast update.  Had also stopped doing MS updates.  Then I went and did a cleanmgr.exe (Disk Cleanup) and cleaned up everything including system files.  To my surprise (which I haven’t seen before) after this it went into “Configuring Windows xx% Do not turn off” on shutdown, then of course ditto on start-up, which now took ages – probably an hour at the 100% stage!, followed by “Clean-up in progress do not turn off”, which took about 3 hours and I thought had hung.  The total disc usage reduction was 3.8 GB (!) stated by Cleanup.  This does seem to have done something, the machine starts and shuts down quicker and the wifi also starts quicker.  Weird.
