Hi all

wanted to check with all the experts here regarding TM Unifi. I just had Unifi installed at my place last week but the WiFi signal is very weak, especially upstairs. The "router" or "residential gateway" they gave me is some brand called InnaTech RG4332.

I was wondering if I can swap out this router for something else like an Apple Extreme or a TP Link or whatever.

Can someone please let me know if this is possible and is it very troublesome to re-config everything? I'm not that IT savvy

Thanks in advance.
