Our shared internet network goes down when our friend who pays for a unlimited LTE plan leaves. His phone is essentially the main router. However, recently we decided to create a local network aswell. At this point, I've set up our secondary router (Linksys WRT54G) as an access point. However to do that, I had to disable the DHCP. Is it possible to enable DHCP when the internet connection when the main router goes down, so our devices automatically get assigned IP-Addresses?
In short: Phone (LTE) (used sometimes for internet access) -> Linksys (Either for just LAN access or internet AND LAN access) -> Devices When the phone is gone, the Linksys should start assigning IP-Addresses, since the phone can no longer do it.
If I’m understanding you correctly, you and a group of others connect to a WiFi network provided by a friend’s cell phone for internet access. When that friend leaves you and a group of others connect to a different WiFi network without internet access so you can continue to have a LAN for the computers to use. If that is the case why did you have to disable DHCP? Turn it back on. – Appleoddity – 2018-12-09T15:33:43.853
Maybe you are suggesting that you have all your computers wired to the Linksys and they additionally connect to your friends LTE hotspot via wireless? Please [edit] your question and clarify all of this. – Appleoddity – 2018-12-09T15:41:32.127
