Wireless Connection Has To Go Both Ways?

Question

I was having a chat with a friend yesterday and I realised something, or I didn't understand something.

People always say get a more powerful router if you need go further away. But you could have the most powerful router in the world, but if computer had a rubbish wireless adapter, surely it could only receive information and not send it?

Answer 2

You are correct. If your laptop is unable to transmit its requests with enough power to reach your router, then it won't matter if your router is more powerful or not. Both points of access have to have sufficient signal strength to work. Not to mention the further away you are, your laptop will have to crank up it's transmission wattage to try to reach your router, thus reducing your battery life.

Answer 3

Yes! The limit on distance is caused by the transmission power of each device. This is normally set at a level dictated by radiation safety levels. If the router is set up correctly, as high as possible and totally clear of obstructions (walls, televisions, fridges and even people are obstructions) you will get better performance. The power of a machine's card is always going to be low as you need to sit fairly close to the antenna. If you really need to get longer range you need to buy a wireless range extender, this locates between the router and the machine and simply relays the signal.
