Re: only getting 23mbps on blast!!!

Not exactly true.

My area was recently upgraded to D3 and blast is now 25/4 without powerboost. It was previously 16/2. We do not have an Extreme 50 tier but do have Extreme 105.

Look at what I said: "When Blast is upgraded to 50/10, there is no offering for Extreme 50."

I'm sure that rollout will happen sometime in 2013, but until then I'm okay with paying extra for 50/10 if it means not having to deal with outsourced CSRs telling me that PowerBoosted speeds of 25/4 are what I'm supposed to get with "Blast!"

And when you get the upgrade, you will be upgraded to 105/20 for the same money you pay, if memory serves. So sit back and enjoy the speeds.

I am new to Comcast and got the Blast 6 month promotion. I was getting 35/6 until a couple of nights ago. My connection went down for about 12 hours. When I called technical support they did some kind of reset to my modem (Motorola 6121) from their end and said that sometimes things get out of sync. Since the reset I get 25/4. When I subscribed at the local office they said I would get Blast for 3 months and then drop to Performance so I wonder if this is what happened. If it is, it happened a month early since my service stared October 15th.

In CO the speeds for Performance are 15/2 and the speeds for Blast are 25/4. If you were pulling in 35/6 then it was overprovisioned, as a lot of areas are.

Perhaps the 35/6 speeds quoted were just the temporary Powerboost speed bursts (which trick many of the popular speed tests) and not the actual sustained speeds that they were receiving ?

Correct, specifically on the Ookla branded tests you can see precisely where PowerBoost kicks off with the Performance tier every time in the middle of the download test. It starts at 25mbps and bumps down to 16mbps. "Blast!" however doesn't throttle back for the duration of that test.

I always found that a little odd since PowerBoost is reported to be based on the amount of data transferred rather than based on time.

Nobody asked this yet?

Mike...are you doing the test over wireless?

That 23 mbps speed does look suspiciously like a WiFi maximum.

I've got a ASUS RT-N56U and i get 34-36 MBPS on average on my WiFi connection. We do have a small one floor apartment so it helps. 802.11g maxes out at approximately 54 Mbps, whereas 802.11n can reach theoretical speeds of 300 Mbps (actual results will vary).

Maybe, but with my connection 50/10 via wireless, I see no difference wired or wireless.

Wow. I'd love to know how to get that speed over wireless. I get 50+ but only when plugged in.

If you aren't seeing the full potential of your "N" capable network, I would look at your encryption settings, chosen band, channel width & DFS.

As example; my settings:

Security: WPA2 Personal / AES
Standard: N Only
Band: 5 GHz
Width: 40MHz Only
Wide Channel: 159
Standard Channel: 157 ( 5.785GHz)

I have blast Houston Meyerland Willowbend area I am getting 24/3.5 I use to get about 2 to 3 mbs faster. I would love to have 50/10 I have just blast not the higher level

Some of these options are missing. I may just be dumb.

Not all routers support 40MHz wide channels, which means your max potential throughput is half. It should still be plenty for 50/10mbps, so you might want to look at other potential fixes.

5GHz N is great up to a point, but the higher frequencies result in vastly reduced range. For example, my network uses two AirPort Extreme routers positioned roughly 50 feet apart in a straight line. This is basically the sweetspot for most routers for the purposes of extending networks. Any further and your throughput goes down the drain at the expense of more range. I use the ethernet ports on both routers for wired clients as well. If you use wired connections for a particular application you may as well...it will reduce the overall amount of radio traffic.

Client adapters aren't all made equally. Most laptops and many routers only have two antennae. Some only have one. The best have three or possibly even more and that helps with MIMO and radio diversity. In addition, some devices only have two-stream radios rather than the newer three-stream ones. Most desktop oriented client adapters like PCI/PCIe cards and USB devices are downright awful.

I figured out that it is my work laptop that is hamstringing my speeds (can't adjust settings). My Galaxy Nexus gets 40+ on Speedtest's app. When I get a new laptop, I'll have to configure and re-check it.

At least you are eliminating variables.
