WLan Repeater using USB WLAN Adapter
I know there are already many questions and tutorials regarding this topic, but most of them seem to go in a slightly different direction and none of them could really help me so far.
So what I'm trying to achieve is a temporay WLan Repeater-setup. I want my build in WLan card to stay connected to the Router, while my TP-Link Adapter runs as AP. But I only want to use it once in a while. Therefore I'm looking for a lightweight solution which, as far as possible, works without changing any System properties and dont need something as a DHCP server which is permanently running.
I got an AP running using hostapd, but now I dont really know how to move on from here. Do I need a DHCP Server at all, or can I just forward any conecctions and requests to the router? If so how could I set this up? And how do I keep my internal wlan connected, after disabling the network-manager service in order for hostapd to work? Would it even be possible to get the whole thing to work using only my internal Wlan? I mean Windows could do it, so Ubuntu should be able do do it as well, right?
The perfect solution would be transfereable into a bash script, which then starts the process inside a terminal.
Any help would be very much apreciated.

You don't need a dhcp server if you set your IP addresses and gateway manually on the client machine.

You need however to enable IP forwarding firstecho 1 > /proc/sys/net/ipv4/ip_forwardfor one-time (i.e. until reboot) forwarding on the AP

@spacelander ok but how to i tell the computer to forward all the connections from the AP to the router? right now theres only the AP running with hostapd which i can connect to, but the devices obviously dont have internet access.

You need to enable something called IP Masquerading on your firewall. I haven't done this in a few years, so I didn't respond only comment. I would suggest reading help.ubuntu.com/lts/serverguide/…

Alternatively try setting up a bridge. This is described here: help.ubuntu.com/community/NetworkConnectionBridge
