Markie posted : In my opinion they should only provide 1, 5, and 9 as channel options BUT the problem would be legacy 1-6-11 deployments. Channel 13 would be on Euro routers.

Regardless, 2,3,4,7,8,10, and 12 should just be removed. There's NEVER a reason to use those - ever.

MovieLover76 posted : Most newer routers aren't dead-set on channel six, you can switch the band through the web interface, and many routers now dynamically choose 1,6 or 11 based on the AP's they detect around them.
putting an ap on any other channels is worse than adding another router as on channel 4 that AP will cause interference with router using channel 1 or 6. Instead of just affecting routers using one channel 1,6 or 11 which enables the most AP's to function.

In my opinion consumer routers should only provide 1,6 or 11 channel options.

MovieLover76 posted : Yea right now 5Ghz is free and clear. When I moved to my current apartment the wifi was absolutely horrid in my apartment, I can always see at least 15 APs

I switched to a dual-band router and almost all of my traffic goes over 5GHz, I was surprised how many devices supported this very underutilized band, even my older blu-ray player and my Galaxy S2 support it.
In this 2.4 ghz nightmare area, 5Ghz is wonderful right now, I can only see one other AP on the band and real throughput is normally 180mbps to my desktop 450mbps adapter.

But newer wifi revisions rely on 5Ghz by default like 802.11ac, the 5Ghz band is going to eventually get more crowded and is capable of using much more spectrum including 80MHz and 160MHz channel support, 2 to 4 times the spectrum wireless N can use.

Spectrum changes take awhile, this spectrum is in use by the government, they'll have to vacate the spectrum. And hardware manufacturer's will have to build wifi gear that utilizes this additional spectrum, before 802.11ac really takes off would be the best time to do this.

For urban and apartment dwellers this is important. 5Ghz will eventually become crowded like 2.4Ghz in many areas.
To dismiss this rare good decision by the FCC as not important is short-sighted.

Yes, yes it is...

There's a good reason for that. That is the most common set of non-overlapping channels. The rest of the channel have slightly different center frequencies, but they overlap each other.

Markie posted : Which is good. 2,3,4,7,8,10,and12 should NEVER be used. The only channels that should ever be used are 1, 6, and 11 as a set or 1,5,9, and 13 as a set. That's it. Ever. Using the in between channels causes and is subject to far worse interference than two AP's on the same channel since they can't use CSMA to play nicely.

RWSI posted : Some of the signals you can't see doing a standard wifi scan. Over the decades different non ssid broadcast wireless devices have been deployed. Some of these devices are designed to wipe out interference. The only true way to see is to have on hand a very expensive spectrum and special antennas. These signals could be ruining your home wifi at 5gHz and you would never know it. Adding more spectrum only helps the few who can afford the good stuff coming down the road but gives a wireless ISP like us more room to grow.

I think they're jamming 2.4ghz because that's the default of most routers. The range in 5ghz mode seems acceptable.

2.4ghz is horrible. I'm not even in an apartment. Everything wants to use that band. I have a pair of wireless outdoor speakers that obliterate 2.4ghz wifi when turned on, regardless of what channel you use. :(

I have to maintain a couple APs on 2.4ghz because we have cell phones and a NEST thermostat that can't pick up 5ghz.

And they all default to 1, 6, or 11; even when they're on auto.

I've got a couple of access points around my house on 2.4GHz for phones, and devices that can't pick up 5GHz. They're all on channel 8. I've got my neighbor on channel 4. I do a quick Site Survey and see a flood of AP's on the big 3.

I think the issue comes down to range. 2.4 simply works better.

It has better range but when everybody in my apartment building all has 2.4ghz routers (if not two) then it completely ruins that. I have a (pre?) 802.11ac router (netgear r6300) and the 5ghz works flawlessly compared to the 2.4ghz band. Much better range on 5ghz due to less people using it.
