I have an ASUS board with an onboard WLAN card. My pc is connected via a normal LAN to my router in a completely different area of my house (out of range for this WLAN). For months, I could simply connect my phone and other WLAN devices to the WLAN my pc send out. From one day to another (after an avast startup scan) the firewall blocks this. If I disable the firewall everything works instantly fine again, but with active firewall (of course with the allow_internet_sharing_flag) it blocks all internet access on all devices.
Windows version: Windows 10
Avast edition: Free 23.4.6062 (build 23.4.8118.762)
Avast settings you changed from default:
- Allow internet connection sharing mode = true
Exact error messages: none
When the problem first happened, and when it repeats, what triggers it: around 3 days ago. The problem persists.
Any steps you already took to try fixing the problem: - Lots of reading
- Setting private and public network rules in any combination
- Followed a guide about how to fix it supposedly - changed the icmp timer rules - did not do anything and was reverted afterward.
- discarded all custom rules one by one
- Reinstall Avast
Any recent changes to your system, its configuration, or your network: none
Finding anything about this bug proved to be difficult, the vast majority of the search hits are idiotic 10 min tutorials how to press the sharing flag…
