Wifi settings – mode, channel, bandwidth

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.

CHANNEL: This is not a great article, but tolerable starting point How to Boost Your Wi-Fi Speed by Choosing the Right Channel  (

    There is no room for panic in these situations. You can only go on and try the basics first. Check if your connection has been reset, check your modem, router, check the status with your ISP. If everything remains unchanged, then you’re gonna wanna turn to more advanced stuff. I can offer some insightful advice and tips in the form of a comprehensive guide: https://solutionbay.com/solutions/no-internet-connection-causes-troubleshooting-fixes-computer-phone-tablet
