Wireless AC (R7000)...confused on my home network

[SomeGuy133]

Alright so I have 2xR7000 and have 600Mbps 2.4G and 1300Mbps AC set up on 5G

My understanding is to get 1300Mbps it uses 600Mbps 2.4G and 866Mbps 5G to make the 1300Mbps correct?

Why do I only get 866Mbps on my S8 and laptop (Intel dual band 8260AC). Need 4 band?

How do I get AC to work exactly?

Note I picked the best channels given the channels and routers near by and I am 1-10 feet away with direct line of sight and everything appears to be programmed right in the router.

2.4G
There are a piss ton of routers in my area but I live in a house with good walls and only one house is next to me given there is a road, pound, field on 3 sides and a house on the 4th side and each house is on 1/4 acre lot so only like 1 router is actually even remotely close to me so hgihest signal is like -80db or less on 2.4G

???That is a pretty clean airway right if nearest signal is -80db? That is like 1 or 2 networks at -80db to -90db and like 5 or 6 that appear and disappear at -90db

5G is 100% clean

I also have 2 of these in the house. 1 on top floor and one in basement and both get about same signal being 1-10 feet away and on different channels that get 0 interference between my two routers. Like channel 1 and 12 for 2.4 and 5.8 and 5.2GHz for 5G or something like channel 161 and 43 respectively or something.

2.4G signal is -30db to-40db at like 5 feet

5G signal is -30db to -40db at like 5 feet depending on where i set my S8 according to wifi analyzer.

From 5 feet away.
5G=866Mbps(not consistently(400-866)) which is max for 5G
2.4G= 192Mbps max (120-192Mbps) which seems offal.

Also newest firmware is installed.

Any input?

Your adapter only supports speeds up to 867Mbps - http://www.intel.com/content/www/us/en/wireless-products/dual-band-wireless-ac-8260-brief.html

To clarify the channels on 2.4ghz, the only channels that don't overlap with other channels are 1, 6, and 11 - so for this reason APs should always be configured on one of those three channels, and if there is a 4th AP in the vicinity that uses 2.4Ghz, you will have channel overlap and other problems.

I hope this helps.

No, 1300Mbps is 80Mhz of 5Ghz spectrum only. As Cmustang87 mentioned, your Intel adapter is only AC1300 (867Mbps max), while the r7000 is AC1900 (1300Mbps max).

If you are only getting ~192Mbps on 2.4Ghz 802.11n, you are likely only using a single 20Mhz channel. To force the r7000 into 40Mhz operation, in addition to picking channel 1, 6, or 11, you may also need to disable "20/40 MHz Coexistence" to prevent 20Mhz fallback when it detects something else on an adjacent channel. Your NIC manual doesn't mention max rate for 2.4Ghz 802.11n, though it does mention 5G is 3x faster than 2.4G in its marketing blurb, suggesting that it may only support 20Mhz (289Mbps max) 802.11n operation itself.

correction I am on channel 1 and 6 since neighbor is on 11.

So is wireless AC just 5G i thought AC was using 2.4G and 5G at once?
Never mind, Googled again and yea AC is only 5G...I thought AC was using 2.4G and 5G as combined for more speed. Wonder how i thought that lol :/
and see the post above someone explaining it

I have 20/40mhz coexistence enabled. What happens when I disable it? Does it run at 20 or 40Mhz?

highest signal is -80db thats pretty good as in little interference right? I am sure outside house interference will be trash.

I know my wifi blasts to about 1000 feet away lol. I had to enable aggressive wifi to mobile hand off because cell wouldn't switch fast enough until out of my neighborhood lol

Spoiler: wifi

When you disable 20/40mhz coexistence + set 'up to 600Mbps', it should force 40Mhz operation on the R7000 assuming it wasn't already in that mode. That option is enabled by default, so you don't end up unintentionally jamming other 2.4Ghz WiFi networks.

okay. I had 600 and 20/40 coexistence so i'll turn that off and try again.

is the 8260AC and S8 400MBps devices since it is 2 band?

2 band is either 300 or 400Mbps

okay interesting turned off coexistence and moved to channel 1 for upstairs which is cleanest and channel 11 for basement:

I get 300Mbps on laptop for 2.4G now but S8 is still 150-192Mbps range.

Spoiler: channel 1 and 11 for NSA sucks
