    Hey guys!
    I'm going on holiday soon, and, as we all know the wifi at the hotels has very poor signal.
    I'm going to take with me a router and try to boost its signal.
    So how can i do this the easiest way? i want to use my router to connect to the hotel's router as a client, and then re-emit as an access point for my phone.
    thank you!

    If they have a LAN connection available, that's always the better option. But if it's only wifi ...

    On the Basic->Network page, configure Wireless Client mode under the WAN w/ your choice of freqs for the wireless client connection to the hotel wifi. Then goto to the wireless section for that freq (on the same page) and configure it as Wireless Client (it will be greyed out and disabled if you don't first enable Wireless Client on the WAN).

    What this does is convert that radio (AP) into a wireless client and virtualizes the WAN over it, thus replacing the wired WAN (you'll then notice you can optionally reassign the WAN port to the LAN). From that point on, you configure the router just as if it was using the wired WAN (configure a DHCP server, DNS, etc.). Just make sure the local IP network on your own router doesn't conflict w/ that of the hotel's local IP network. IOW, if the hotel is using 192.168.1.x, perhap uses 192.168.2.x. Or just pick something obscure and unlikely to be used by the hotel (e.g., 10.39.81.x).

    Depending on the wireless chipset, you may be able to virtualize that same freq into an VAP, which would be helpful if the hotel only supports 2.4GHz, thus leaving you w/ only the 5GHz for your own AP. You just have to try it and find out.

    don't forget that wireless repeater in tomato is vulnerable to KRACK - not that it would matter in hotels where almost everyone knows the password :)
