Intermittent loss of wireless internet connection on reboot.

This is the second time i have this problem.

The bug/issue

  1. What you did: Booted computer
  2. What actually happened or you actually saw: For some reason after some computer startups I have no Internet connection. Repairing the connection does not solve the problem and the rest of the computers sharing the same router have normal Internet.
  3. What you expected to happen or see: normal functions
  4. How you tried to fix it & what happened: Repairing the connection does not solve the problem. When I go to the wifi adapter and uncheck the Comodo driver my Internet is back. When checking the Comodo driver the Internet connection stays.
  5. If its an application compatibility problem have you tried the application fixes?: can’t say, no idea
  6. Details (exact version) of any application involved with download link: N/A
  7. Whether you can make the problem happen again, and if so exact steps to make it happen: just install cis and after a view hours\days it’s there. sometimes immediately sometimes later.
  8. Any other information (eg your guess regarding the cause, with reasons): No

We would very much appreciate it if you would edit your first post to create an issue report in line with the bug forum guidelines and format here. You can copy and paste the format from this topic.

To understand the reasons why we ask you to follow these guidelines please see below.

Bugs/issues can be impossible or very time consuming to fix if developers don’t have enough information to reproduce them. Since CIS is free, development time is limited. So if you want your issue fixed, please use the format below to describe it.

To avoid clutter, issues not described in the format below your post will not be moved to the ‘moderator verified’ issues topic. This means that the developers may not look at it.

Best wishes and many thanks in anticipation


Thanks for the bug report in standard format I have edited you report and title to clarify it - hope that’s OK. Please do check it to see if all is correct.

Could you please add your UAC setting and service pack in the appropriate place in the format? Then I will forward to format verified.

Also please answer:
4. Any other major changes to the default config (eg ticked ‘block all unknown requests’, other egs here. )

Best wishes

This has apparently happened to my wife 2 or 3 times and she was able to resurrect the connection by disabling and re-enabling the wifi adaptor.

Thanks Ewen. Yes I have seen other reports too, so I think a few people have this problem.

If you have time please add a bug report to this topic as it may help narrow down the range of environments where this is being experienced. (Or not but thats useful to know too!)

WIFi adapter is an other issue, this does not resolve with that action.

Going to throw this out there…

Is your WIFI adapter/network set as a trusted network?

I’ve had a similar problem that setting it to a trusted and defined network helped, but I may be thinking of a different firewall/application.


Thanks for the added info. And for making the report in standard format

Moving to format verified


Sorry, but I can’t post a bug report as I only have second hand knowledge of how the issue manifested itself and how the fix was implemented and consequently couldn’t complete the bug report faithfully.

No problem :slight_smile:
