So you want to increase the signal strength of the hotspot? It doesnt look like your router is capable of becoming a repeater. It could become an access point, but the requires it is plugged into a modem.

Nah there isn't a modern or anything for this hotspot.
I'll buy some new antennas and a signal booster tomorrow. Thanks for all your help, I wouldn't even know what Google searches to try haha
