I really hate repeaters and would rather do the work to run cable to another access point.

But on your point I did recommend a survival game for my friend group to play after playing a little and we all bought it and played for a month and then no one wanted to play it after so I feel like my recommendation was not great.

Maybe it was set to the same wavelength as the router and cause destructive interference. IME repeaters work quite well if you don't have any other option.

Repeaters can add fuel to the fire if there's already a lot of access points around. Especially on 2.4ghz which has limited number of channels. It can be helped by reducing the transmitting power on all devices.

Id rather recommend the wall plugs (they connect to wall power socket and transmit Internet over power wires via RF), if you can't run Ethernet.

The wifi repeaters work the best if you wire them to the network and always disable 2.4GHz on everything. (Basically not using them as repeaters)

Razer gear the quality of their stuff has gone down since they became a publicly traded company.

A friend of mine had the problem that her rather old tablet did not support a GSM stick, so I recommended her to buy a newer one. Which did not support any kind of GSM stick, either.
