Many fail to understand that their router broadcasts more than adequately but it is competition with neighbour’s wifi that plays havoc with their wifi connections?
Very often it can be the 'free' channel that causes problems.
Here's a typical scenario. There's 3 routers using channel 6 and 3 routers on channel 11. No routers on channel 1.
You scan the wireless channels and see channel 1 as empty. You then use this channel.
Chances are this channel has at least one the following, wireless doorbells, wireless telephones, bluetooth devices, wireless baby monitors, AV transmitters etc. WHY? These devices avoid populated channels too. So they wont choose 11 or 6 usually as they're already in use.
1 of these devices is much more likely to wreak havoc on your WiFi. This is because many of these devices aren't regulated in the same way that wifi routers are. A WiFi router will work quite well on the same channel as another WiFi router.
A wifi router and several cordless phones on same channel = a nightmare.
several wifi routers on same channel = some performance loss but not too bad
Of course on inssider you never know if the channel you are choosing is populated by these devices. You only see wifi routers which are a very small part of the true picture.
