Problem: if for some reason router 1 does not have internet, i turn on WIFI adaptor for hotspot. When both LAN card 1 and wifi adaptor are enabled, internet connection doesn't work. But when I disable LAN card 1, internet works from wifi adaptor but I loose LAN to other PCs and NAS. How can I fix this?
Here's my setup:
LAN card 1 (Built-in) ISP Cable Modem >>> Router 1 >>> LAN 1 (using DHCP provided by the Router - full control) IPv4 Address: 192.168.1.201 IPv4 Subnet Mask: 255.255.255.0 IPv4 Default Gateway: 192.168.1.1 * Router 1 - this is for internet access and all other LAN computers and NAS devices etc.
LAN card 2 (wifi adaptor) - any working wifi-hotspot as ISP >>> Wireless Network Connection (using DHCP provided by the hotspot - so cannot change anything here ) IPv4 Address: 192.168.43.44 IPv4 Subnet Mask: 255.255.255.0 IPv4 Default Gateway: 192.168.43.1
