Wifi settings – mode, channel, bandwidth
This is a comprehensive article: 10 Tips To Fix – WiFi Connected But No Internet Access
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

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 (
