Optimum WiFi speed increase

I saw an ad on TV saying that the download speed of Optimum WiFi has been increased to 15 Mbps. I only got 9.5 Mbps in my test, but the speed has definitely been increased.

That little green "79" in the lower left part of your screen wouldn't happen to be your signal level in negative dB, wouldn't it? If it is, your signal is marginal, and +9Mbps is a very good result.

The area you were in (where?) may be too congested on the 2.4GHz band to ever get up to 15Mbps, and there's a very long laundry list of factors influencing speeds:

• number of other APs within reach, whether you can see them or not (handheld devices tend to have poor WIFI antennas, like: my iPhone and Android phones consistently show 3-5dB lower signal levels than my laptop in the same location, and are seeing distinctively less APs, yet their signal is there!)
• By-the-second amount of traffic to/from all clients to all those APs
• noise levels from all sources, including wireless cameras (especially video baby monitors) employing direct-sequence spread-spectrum channel use, Bluetooth devices
• APs that can't see your (sending) signal, but who're talking over you to CLIENTS that are closer to you than the AP itself - the hidden-talker problem that is essentially pure and sustained noise to you.
• APs that employ 802.11N, and who are owned by inconsiderate jerks that think using 40MHz (8 out of 11 usable 5Mhz channels!) instead of 20MHz (4x5MHz) bonded channels is without consequences (or provides a performance boost in the real world for them - NOT, it's just hogging channels)
• APs that use partially overlapping channels, e.g.: channels OTHER than 1,6,11 in North America. Again - owners are jerks, or don't know WTF they are doing: use channel 3, and you're disrupting (=creating noise) channels 1,2,4,5,6 and 7!
• whether you are using 802.11G instead of N (some OptimumWifi APs support N, as observed), with N definitely being the better-performing protocol under the same RF noise and channel-utilization conditions.

No, I didn't say it was easy for you as an enduser, to recognize why your wireless speeds are what they are. Performance analysis in this space is very difficult, even with professional tools and knowledge.

that 79 should be battery level.

I thought there was something that saiid that they bumped it up to 15/5 and people were saying how it's faster than their standard 15/2 connection

True, and it's been like this for a couple of months.

Opening up the caps on WIFI doesn't necessarily mean you achieve these speeds, as the RF environment that defines actual performance is completely uncontrolled by CV and for the most part uncontrollable (other than changing the 802.11 channel occasionally if you detect too much noise and suffer high error rates, which is what an enduser would do as well) - "up to" really means exactly what it means here. There are no guarantees of performance for unlicensed bands, it's all a wildcard.

Regarding this from your previous post:

• APs that use partially overlapping channels, e.g.: channels OTHER than 1,6,11 in North America. Again - owners are jerks, or don't know WTF they are doing: use channel 3, and you're disrupting (=creating noise) channels 1,2,4,5,6 and 7!

You're telling me that anyone and everyone should be using either 1, 6 or 11 even if that by itself causes interference to the point of being unable to use WiFi or causes perfomance issues itself where you can't even get half the speed on your speed tier?

The problem is that if you use Channel 3 you actually "interfere" with channels 1 through 7. There are really only 3 non-overlapping channels for Wi-Fi even though there are 11 US channels. See the chart 1/2 way down in the following link on "WiFi channel overlap and selection"

Given that, then why make other channels available aside from 1,6 and 11 if that's the case given your argument and subsequent link? Either way one slices it...it seems impossible otherwise to cause interference.

I wondered about that also, but I looked at it a long time ago and the literature makes it clear that if possible you really should use one of the 3 channels.

I suspect, but do not know if it is the exact logic for having more channels, if there are more than 3 networks with very strong signals in the exact same area you can move them to the intermediate channels and get slightly better performance even if there is some interference. So while rule of thumb is use 1,6,11 there may be a situation where 1,4,7,11 or something like that makes sense.

The "79" is the percentage of battery power remaining. The test was performed in downtown Morristown, NJ.

Are there any 5 GHz APs?

I've never seen any. I don't think that they exist in the Optimum Wifi world. I don't think that 5 GHz APs are necessarily suitable for this sort of application.

Definitely noticed a speed increase. At the platform of the New Brunswick train station I get 7 megabits down and 1.5 up.

Definitely no increase in CT - at least in Norwalk and Fairfield. Yesterday the speeds in both areas were abyssmal.

Optimum Wifi provisioned speeds are uniform across CV's entire service area.
