Wifi settings – mode, channel, bandwidth

Read this: and this (from tpg)

Bandwidth Channel Mode
2.4 Ghz 20 Mhz Auto 802.11g/n  This ensures that pre-2009 adapters (like the one in the ground floor) can receive 2.4 Ghz signals.
5 Ghz 40 Mhz 149 802.11ac/n

If you use 802.11n with 20MHz channels, channels 1, 5, 6, and 11 – I think best is to set to auto

MODES OF 802.11

My router has FIVE modes: 802.11 a/ac/b/g/n.

a and b were released in 1999, g in 2003, n in 2009, and ac in 2013 (ac builds on n).

a/ac/n use the 5 GHz band.  b/g/n use 2.4 GHz band. Thus n is common to both.

BE AWARE THAT OLD ADAPTERS CANNOT RECEIVE n. SO YOU NEED TO SET UP APPROPRIATE LEGACY MIXTURE 

===DETAILS==

BANDWIDTH: The wider the channel, the more you can get out of it. For maximum range, use 20 MHz, for maximum bandwidth use 80 MHz channels. i.e. 2.4 Ghz has a lower max speed but provides more distance whereas the  5 Ghz has higher max speeds but covers less distance.

First, his photo:

 

Ian Earl This bloke has done this before went bankrupt. Before this one went down believe took family for holiday to hawaii

Sue Volpe We dealt with Shane Guymer a few years ago. We signed a contract with one builder, yet it was his company that was building the home which was somewhere in the small print. Would have to be the dodgiest person I have come across. He has worked under a number if business names. Im sure next week he will set up another company and keep going ripping off innocent families.

Kevin Vermeer That’s why they haven’t paid my $1200 invoice. Looks like I’m one of the lucky ones only down 1200 .
But I saw it coming although I was assured all was good I got out.

George Penna This same guy was involved with a different company 10 years ago it also went under. A friend of mine lost $300k

Andrew Killingsworth Shayne Guymer is very easy to pick as a wheeler and dealer. You know instantly hes not one worthwhile building a business relationship with.
