I don't know if BitDefender is involved at all, but I'll ask the question anyway.
I'm trying to get Win10 Mobile Hotspot to work, using Lenovo P70 laptop which is ethernet cable connected to a router/modem/internet. I want to share its wired ethernet connection, via the Win10 Mobile Hotspot functionality, so that nearby devices (phones, other laptops, etc.) can connect via WiFi to the P70, sharing the P70's wired ethernet connection to the internet. Same concept as using mobile hotspot functionality on a smart phone, to provide internet via Wifi (to the phone's hotspot functionality) to nearby laptops, tablets., etc.
Everything is set up and configured to work, and it all looks like it's correct. Except that the nearby client phone and laptop do not successfully connect to the P70's Mobile Hotspot SSID. The phone fails to be given an IP address, and the laptop connects (ending up with a bizarre IP) but "no internet access" (no doubt because the IP address is garbage).
The issue may be elsewhere, but I'm just asking here if anybody who's running BitDefender has ever successfully implemented this Win10 Mobile Hotspot functionality, and had client phones and laptops successfully connect via WiFi to the Mobile Hotspot running on the PC running BitDefender. If so, did you have to do anything special in BitDefender to facilitate the success? Firewall exceptions? Anything?
