Imagine you are speaking to someone. The further away they are the harder it is to hear you and they may end up having to say, sorry please repeat that (that's your data rate dropping as it takes more time to relate given amount of info). Then imagine someone drilling near by. When the person is near you the noise of the drill does not overcome your talking. As you move further from them the noise of the drill has more effect in terms of making you harder to hear.

Distance reduces the received signal strength thus the signal to noise ratio also decreases, even with a constant level of noise. It's the ratio of the TWO things that defines how much information peer second can be sent

The important thing for a consumer such as yourself is to aim for the 802.11n wireless standard when buying a new laptop (also called "Wireless N").

At the moment that's the latest and best protocol.


Er actually 802.11ac is latest WiFi standard.

Can you actually buy a laptop with this standard today or in the making?

We've been able to buy devices with ac cards for a few years now, the routers have been around for 3-4 years. I guess this technology is yet to arrive in Tseri :D .

Well mobiles have led the way with this, been in Samsung Galaxy phones since the S4. Laptop wise it is starting to become more common now. A quick look a pc-world.co.uk website lists 109 laptops with 802.11ac wifi built in vs 228 with 'standard wifi' (which would be 802.11n).

Ha! Things move slower in Cyprus mate… all the previous stock needs to run out before they bring in the new stuff, or it’ll be priced astronomically so you buy the old stuff. :lol:

- If you are further from the broadband hub, and say you pick up 2 bars instead of 5 bars, why should your upload/download speed go down?

Why does it depend on the signal strength? Why isn't Internet On or Off?

Surely, the bars should indicate how far away you are from the source and not influence the speed (a separate thing, surely?).


I get the same problem plus my wireless keeps dropping out when I use my iPad even when I'm next to the router. Change the channel on the wireless router and it all works ok for a few days. Neighbours wireless interfering with mine and possibly yours :?:
