Wheres my AC?

[JewishBacon]

So I just got a linksys EA6500 AC router. I can do the 2.4 GHz band, and the 5 GHz, but I dont see the AC band? Am I missing  something here??

AC doesn't mean another band it means it has more than one 5Ghz band itself to choose from to give more bandwidth capability.

Your in mix mode on the 5GHz, put it to AC only with 80Mhz channel width. Also Linksys has a issue on the 2.4Ghz side were it will drop the link speed so set the channel width to 20Mhz manually.

the band is ac 2.4ghz and ac 5ghz its not a separate band from what i believe. plz keep in mind i dont really care much about networking so i have little knowledge on it.

What happens if you set it to auto, I have that same router and I always left my settings on auto.

If you have around 10 clients on the 2.4GHz is drops the rate to 5-11 Mbps for some reason, it's can only run at 20MHz anyway so your not loosing any performance. Manually setting it seem to resolve this issue.

Hmm good to know didn't hear about this before.

It seems to effect the EA 6500 and below the most, also there's some pretty gaping security holes in the older firmware so using the new firmware is recommend.

That sounds more like a scheduling issue that you would only expect to be able to get around on a very high end AP. Also that range is right around the area of wireless g, are you sure you didn't have a legacy device connect?

No it's a bug in the firmware, I run 3 UniFi AP AC for wireless now anyway. I have my CCNA in R&S and I'm a huge radio nerd so I'm not just guessing here. Also where in the did you get anything about range from what I said?  2.4GHz has a wavelength of 12.5cm regardless whether you use G or N thus it will have the same range granted your outputting the same EIRP with the same hardware, the only difference is your just doing spacial multiplexing across two or three channels.

 

What your talking about is total wireless throughput the AP can handle which isn't the problem here when only one or two of the ten clients are only pulling in a few Mbps at any given time.

Meaning theirs no "scheduling issue" because pretty much all new APs have some sort of time division multiplexing now. It's purely a matter of the chipset's throughput on consumer routers nowadays when you have congested networks, up to a certain point of course. Most new Linksys routers are using Broadcom SoCs from 2008.

I think you miss-understood what I meant by range, I was referring to the data rate range you listed. Your statement about TDM confuses me a bit as TDM is a form of time allocation and scheduling. If you are saying it isn't an issue with total throughput, what do you mean by it is a matter of the chipset's throughput? This may be irrelevant as I never stated anything about total throughput regardless however I'm just trying to understand here as I'm not the most familiar with this particular piece of hardware.

 

And since you mentioned it, I'm about to write my CCNP R&S, have my first exam this week. Hoping to be fully certified by the end of August!

Sorry for the miss communication, it's pretty late here. TDM coupled with spacial multiplexing on multiple stream allows more bandwidth so the bandwidth part theoretically isn't much of an issue but general wireless interference limits this since this isn't a perfect world.

 

But rather what I was talking about is that the wireless chipsets along with the SoCs are usually really cheap on consumer routers and really underpowered so they only are capable of so much load. Considering your getting you CCNP soon (good luck by the way ), think of it this way. Try running an large College campuses entire network off something like a 2611XM vs a 7600 series router, it's not going to work so well, same issue here. The hardware is so crappy for the job that the theoretically link maximums can be achieved. Most consumer routers that have gigabit ports can't route even close to wire speed, especially the budget ones.

 

So my point was that do to the advancements in Wi-Fi quite recently it has come a long way but is completely limited to consumers due to crap hardware causing most problems. So most people's wireless issues stem from their cheap and/or old router but in this particular case it's actually the firmware. But it makes sense, they have to put a router/switch/ap all in a box smaller than most books any on top of that make it stylish and make a firmware with a GUI that grandma can use making not much room for profit and time spent of the firmware.

 

I could have worded what I was saying at first much better if I wasn't so tired but who need sleep right? :rolleyes:

To put it really simply:

a -> 5Ghz

b -> 2.4Ghz

g -> 2.4Ghz (with backwards compatibility for b )

n -> 2.4Ghz (with backwards compatibility for b + g) and/or 5Ghz (with backwards compatibility for a)

ac -> 5Ghz (with backwards compatibility for a + n)
