Living in Japan.

3LDK apartment so not very big.

1gbs fiber.

Currently using a Buffalo whr-1166dhp3

Speeds are abyssmal. Had it 3 hears. I get 40-50 down on wifi and 90-99 on ethernet.

My ethernet link speed is fixed at 100 on pc and can’t change it so I want to change ethernet cable which is easy but what router should I get?

I ordered a TPlink AX80 but I believe it is overkill?

My devices are PC, Smart TV, two smartphones. Sometimes laptop/switch but rarely.

We do lots of 4k streaming, downloading and playing online games together (couple).
