Comcast XFINITY → Re: [Speed] Comcast 2014 Side Discussion about Doubling Speeds

Are you connecting on wireless? if so you should try a wired connection, I had the same results via wireless but once I connected wired I got the max bandwidth.

Thanks, I'll try that!

Man.. Can't believe I have that much of a loss on wireless..

.. and on wireless.. any ideas? I'am only about 15 feet away from the modem/router combo (SBG6580) .. no walls to pass through, just a clear shot..well, there is a couch but that should be ok.

How is your device connecting to it wirelessly? N...AC...G? Using 2.4 or 5 Ghz? Do you live in a condo/apartment building where there's a lot of networks (interference)? All of those things can play a significant role in your wireless speeds.

It's a 802.11n device, that's about as much as you're going to get. If it was an 802.11g it would be half that. Wireless is never an ideal way to transfer data.

I disagree, and I don't have a problem getting full speeds with AC equipment.

I'm sorry but I'm going to have to agree with C4 here. You're never going to get the max theoretical throughput advertised with wireless whether it be 150Mbps, 300Mbps, 450Mbps, 600Mbps of N or 1.3Gbps of AC unless in a strict environmentally controlled laboratory. Maybe close to it with the right conditions, but not exactly it. »en.wikipedia.org/wiki/Throughput

When i had Extreme 105/20 i had no problems getting the full 120/23 over wireless N the speeds were no different then hard wired right to the modem.

Will agree with you mike.
I have had many different routers and have never got anywhere near the levels wireless as I have wired.
With the update yesterday I am getting 177 down, wired.
My Granddaughter was over last night with a tablet that has AC and 15 feet from the router she got 92.72 down. With my Dell tablet with a N, I get about 63 down.

Are you talking about 2.4GHz or 5GHz and in 20MHz, 40MHz, or 80MHz mode. 120Mbps is easy to do on a 5GHz connection in quasi close range, I can even do 126Mbps on 5GHz near my own router. What I'm talking about is wireline speeds and theoretical speeds. Every router I've ever read a review on has never done the advertised theoretical speed that N or AC can deliver. Here's some charts from TweakTown of 1300Mbps AC routers. Notice that on the 5GHz range none of the routers are near their advertised theoretical 1300Mbps. Heck there are even YouTube videos of people taking AC routers and connecting them to GoogleFiber's 1Gbps connection and showing their speed results of being below it.

All I'm saying is that when it comes to doing a speed test, it's best to do it on a hardline like Ethernet.

 
I have a HP ProCurve MSM410 access point that is rated for 300mbps (802.11n).

When I use it on the 5GHz band, I get a 150Mbps link, occasionally 300mbps.

(to see the link speed, on Windows 7, click on the wireless signal strength icon on the taskbar, then select your SSID, then right click to get the drop down menu for that SSID, then click on Status).

Around me, the 5GHz band is all but unused, usually, I'm the only one there.

When I use the 2.4GHz band (in which there are many overlapping users) I'm lucky to see a 65Mbps link speed.

When I do get the 150Mbps link speed, the actual data transfer rate is around 90Mbps.

I'm about ten feet from the access point when I make these measurements.

I try not to use 2.4 GHz just to crowded here and all my devices support 5 GHz. With 5 GHz at 40 Mhz for N devices 80 Mhz for AC clients. I am only referring to speed tests online i have not tried any local network data transfers. But at least with speed tests i always get my full band width.

Of course having top end clients with multiple antennas helps a lot my Ipad wont get full speeds only about 50mbps my Android AC supported phone does and my desktops and laptops no issues.

Well, my wireless adapter on my computer states it's 802.11b/g/n ... Looking at my modem settings its on 2.4 GHz and I live in a house.. very little interference and great signals.

You need a very good dual band wireless card/USB adapter to get the wireless speeds to match your router.
