8 reasons to turn down the transmit power of your Wi-Fi

 

By default almost all WiFi access points transmit at full power (100mW on 2.4GHz). This gives maximum coverage and users see a good signal (“full bars”). However, there are good reasons to turn down the transmit power to a fraction of the maximum.

 

It even makes sense to start with minimum power and increase it until the necessary area is covered.

 

0. Wi-Fi is about sharing, not competing

 

In a congested environment it doesn’t matter if your access point is stronger than the neighbor’s. If your AP can receive other APs it will share the air time with them. All APs on the same channel will give other APs equal access to the spectrum. This is how 802.11 was written.


[Edit: I added this point as an afterthought, since this isn’t obvious to many users.]

I don't have a problem with different tech if it's actually available and genuinely useful.  Clearly, you think it's useful and going to gain further support and I disagree.

 

And yeah, it might have a few devices supporting it, but AX already has an similar amount readying for release.

At any rate, enjoy whatever you want to use.  I think there's not much else to add to this conversation.

Yeah because change never happens.. Even if its not ad, the days of 1 AP in your house have been long gone anyway..  ax is going to have the same problems as ac, and to get the bandwidth your talking use of 160mhz channels - which not going to work on these freq where you have all the overlap with other wifi.. Especially when everyone loves to blast up their power as high as it goes ;)

I don't have a way to lower the transmit power in my Hitron CGNV4-EU router, or am I looking in the wrong place? 😛

From a quick look at the manual I found for that - I don't see anywhere to adjust it either..  That model is a bit dated is it not.. Does it even support AC.. I see some places that say it does, but another manual lists only N?

 

edit;  Ok looking through the manual at the 5ghz setup, it looks to support AC if you enable it??

I have 5GHz enabled, i have the two bands enabled because Nest's "Heat Connect" (which must be connected via wifi for the thermostat and heat connect module, even though they are also connected by wire) keeps disconnecting, from reading online, other wifi devices on the same channel can cause the link to drop, which is nice /s

 

Nest requiring the thermostat and heat link to be connected via wifi makes no sense to me when it has a physical wire connection between it and causes me a lot of headaches in winter months, but that is a different discussion eh!?

So you have a 3rd gen thermostat?  If so then it uses nest weave to talk to your heat link and not the wire..   I think problems your having with those systems would be a different thread sure ;)  Happy to help if I can, I don't have a heat link - that is a EU thing and not something here in the US..

 

But nest weave is not your wifi network..
