Very Slow Time Capsule WiFi Speeds - Disappointing

Same problem here.
Backups via Ethernet, 1mbps transfer rate max.
Backups via Wifi, 700kbps max transfer rate.
I tried reformatting the 1TB HDD several times, I changed the Wifi transmission channels and modes (2,4ghz and 5ghz) with no issues.

Definetly not satisfied. I think I'll sell it.

I'm using 1TB TC as my router hooked to my Comcast cable modem and the USB-to-Ethernet dongle on my MacBook Air.

With AirPort disabled on the MacBook Air so to force internet traffic across the ethernet dongle and using the speed test at http://www.speakeasy.net/speedtest/

I'm seeing

Download: 22608 kbps
Upload: 1531 kbps

I did this again with just WiFi (ethernet disconnected) to my 802.11n Apple Time Capsule and I'm seeing

Download: 10360 kbps
Upload: 1513 kbps

From this I conclude my ethernet dongle gives me 2x that for WiFi on downloads and no issues with my 1TB TC.

Wouldn't you expect 802.11n to easily support 22608 kbps download speed ?

I have a 10Meg down and 1Meg up internet connection. I have noticed that since I put my 1TB Time Capsule in the wireless has been slower than what I have been used to on my old Linksys WRT54G router.

This morning I decided to run some tests and have seen something really weird, when I directly wire into the TC, my test results are 10.XXMeg down and 1.00Meg up, but when I run the same test on a wireless connection to the TC, I get 1.XXMeg up, but only about 300K down, yes, that's K and it's consistent.

For grins, I am going to go back to the linksys and try the wireless test again.

I am running the tests from a C2D MBP 2.33 and am using www.speedtest.charter.com as the benchmarking tool.

I have since connected my Linksys, powered off the TC, and have rerun the test several times. I am getting the 10.XXMeg down and 1.XXMeg up.

This definitely shows that the TC is somehow affecting the downstream link. It's pretty crazy that it is taking it from 10Meg to 300K.

Here are my results using speedtest.net to their recommended server for me.
Using Linksys CM100 cable modem for connection to ISP, 100MB ethernet from modem to TC WAN port.

First the iMac via TC gbit ethernet...

Next the macbook connect via TC wireless n...

As expected, not much difference at all, the bottleneck is my ISP link speed.

Had almost identical results using a Linksys WRT-54G prior to swapping it with a 1TB TC.

As for LAN transfers, I have posted about speeds previously, all were at pretty much maximum.

Used same speedtest.net today at approx 8am PDT and here are my results using the Seattle server, ISP Comcast cable and 1TB TC as router

Don't know if this has anything to do with your problem but when the AEBS first came out several testers were disappointed by very slow speeds. Eventually they realized that they were not using the single WAN port on the AEBS to connect to the wired network. Turns out that it makes a huge difference over using one of the LAN ports.

My speeds as of this morning. The test was run from my Macbook Pro over 802.11n. Really would like Shaw's 25 MB Nitro connection but for $93.00/month I still find that a little steep 😉 This connection is over their 5 MB connection with a Motorola SB5100 cable modem.

OK, I'm not sure about this, it's just speculation, but I have an idea. The problem with AEBS, and why it couldn't be used to backup to USB drives reliably, is that the data being sent there was not acknowledged, i.e. there was no receipt from Airport saying, "I successfully received that data." I would imagine lots of wireless routers don't bother acknowledging - if the data gets lost, another request will surely get sent again. ACKs tend to slow things down - satellite cable modems even pre-acknowledge packets due to TCP's problem with ACK latency. TCP requires decent timing and ACKs to perform well. But you can't have that on a backup solution. You need to ACK the data. So the TC (and now with the firmware upgrade, AirDisk) have to ACK the data, which slows things down, which makes your wireless seem slower. Again, this is all just speculation, but I think it's a reasonable theory.

I posted this earlier but got no responses:

Why is TC 3x slower slower than AEBS?
TC download speed 7700 kbps while AEBS set up exactly the same is 22700 kbps using speedtest.net
DNS the same etc. I am talking about internet speed only. This is the same set up as N only or B&G.

Any Help, or reason why?

???

I replaced my AEBS 802.11n (GbE) with a 1TB TC and my internet downs/ups have not deteriorated at all.

TC or AEBSn made no difference in speed for me either, both max my connection.

I went back and connected my TC, reran the test at speedtest.charter.com and got 10Meg down and 1Meg up and thought maybe it needed a restart. I have left it alone all day and came back a little while ago and was seeing 3Meg down and 1Meg up. I came back here and saw the test results some of you have achieved and decided to switch for consistency.

When I am on a wired connection between the TC ad my MBP I get this:



When I am on a wireless connection, I get this:



Strange?

Here's my result from earlier today using PM G5's (June 2004 model) GbE to TC


and same using PM G5's AirPort card to TC
