Can someone explain, and provide answer to the following:
Background:
- have Xfinity service with DPC3941T wireless router.
- environment is suburbs; each 1 family house is on 0.25 acre lot up & down the street, and about 0.5 acre separation between my street and parallel street.
- channel rating from wifi analyzer for 2.4 ghz band says None, try alternative WiFi Band 5 GHz.
- I have disabled my 2.4 ghz wifi and want to run best channel in 5 GHz band.
Using WiFiAnalyzer for 5GHz band:
- shows channels 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 144, 149,153,157,161, 165.
- channels 36, 40, 44, 48 each show an access point count of 11 at < -85 dBm.
- channels 149, 153 show an access point count of 1 each, not sure why.
- rest of channels show 0 access point count
- says best channels are: 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124...
On My Xfinity provided DPC3941T router for 5 GHz band:
- I only have these channels to manually choose from: 36, 40, 44, 48, 149, 153, 157, 161, 165
- Channel bandwidth choice of 20, or 20/40, or 20/40/80.
- The three choices of channel bandwidth does not changes what is offered for manual channel choices.
If I leave channel selection on automatic, the DPC3941T chooses channel 36. Is this good or bad? Should I use that or can I do better by choosing a channel manually and if so then which? Please elaborate on the reason why, given this scenario, to help one understand how to choose a best channel for 802.11ac wifi at 5 GHz band. Thanks.
