Intel Mac :: Slow Transmit Rate On Wireless Network
May 28, 2012
My 2.4 ghz IMac is showing a transmit rate of only 78 on our wireless network while my Macbook seems to work fine in the same location with a rate of 130. Is there any way to increase the speed or is their something wrong with my airport, should be faster. When selecting the option key and clicking on the aiport symbol it shows the following data.
0:8b:5d:af:35:22
Channel 3
RSSI: -72
Transmit Rate: 78
Out router is a BT Home hub, while the modem attached to it is an Echolife HG-612.

I've been following this forum for quite some time after I first got an iPod touch and, recently, an MBP "17.Now, after I did some searches on the internet and couldn't find the answer, Im asking here:My MBP comes with a built-in draft-n wireless card. I bought a draft-n wireless router just for the purpose of utilizing greater wi-fi speeds, but there is one thing I noticed:when I boot MacOS and connect to the wireless network it shows me, tat the transmit rate of the network is 130 (Mbps I presume), on the other hand, when I boot to Windows (via Bootcamp) and connect to the same network - it shows a network speed of 280 Mbps. In both cases the transfer speed are relatively close and go up to 8-9 Megabytes per second.

Random question, I have Uverse internet. The modem is also a WAP. Would it be possible to use an Apple Airport to receive the signal from the Uverse box wirelessly AND transmit a wireless network simultaneously?

Having enormous troubles with using Wifi on my MP. I've had this before and it's a PITA.The transmit rate just drops to 1 (it should be up in the 90s shouldn't it?) Is there any known fix? I'm using Leopard. Should I upgrade to Snow Leopard? Does this solve it?

Is there a way to find an Ethernet Transmit Rate? I'm running a Mid 2010 Macbook Pro. For example, to find the wifi transmit rate, I know I can hold down OPTION and click on the wifi icon in the menu bar and view various wifi specs in the pane that drops down. I also know how to look up LINK SPEED via Network Utility > info > ethernet/wifi, etc....Â
Is there even such a thing as an ethernet transmit rate, or am I creating my own vocabulary?

I just picked up the 2TB and I have a few questions about it. I also just recently talked to a buddy of mine that has the 500 or 1TB version of the TC, but it seems that the setup/options are a little different. For example I would like to just use the TC as N only on the 5Ghz band, but it doesn't allow for me to do that. I can check a box for the 5Ghz but it doesn't specify to use the N band only. The "transmit rate" is different as well. Now, I can only select low, med or high instead of 6mb, 10mb etc. What is the transmit rate and what can I do to optimize the TC for optimal performance? I wish I could screen share with someone so I can figure this out.

My Internet has just been upgraded from 2MB/s to 10MB/s. To confirm the upgrade I have used [URL:...] to test my upload/download speeds with Firefox and Safari. I have 2 computers on my network which consists of a cable modem connected to a white airport base station with 128 bit WEP encryption in 802.11 b/g compatible mode. The 2 computers are a dual 2.8 ghz MacPro which is wired directly into the Airport base station by Ethernet and an iMac 1.83 Intel core 2 duo. The much faster MacPro only achieves a download speed of 5.5MB/s over its wired connection while the slower iMac achieves 9.8MB/s - very close to the advertised speed over its wireless connection. These are consistent speeds not one offs so I am wondering why the difference? The MacPro is my main machine so I'd like to have the best speed possible on that. What can I try?

I am deciding to buy a TimeCapsule within next week because my Seagate FreeAgent 500 Gb is already full. But I still not sure about its functionality and warranty coverage.1. How about the file transfer rate in wireless mode(802.11n)?2. Can I use the USB port of TimeCapsule with my old Seagate FreeAgent to expand the capacity?3. Is there any way to install a bittorrent software on TimeCapsule? like Asus WL-500W4. Is it fully support Windows XP?5. Can I use it as a repeater? Is this an option provided in Airport utility?6. I have just purchased an AppleCare for my MACBook pro but I am not sure about it coverage.

I am trying to use a WD Elements external HD formatted to Mac OS Extended, and the box says that the HD should have a USB 2.0 adapter, meaning it should transfer over 400 MB/s. Unfortunately for me, I've had many problems with this HD and it is now crawling at around 2.5MB/s, slower than 1.1 speeds. At the moment, it is at 750MB/93.51GB - About 21 hours. This is unexceptable, and I make HD videos, which are usually from 200 - 500 MB, and this would take AGES! I had no problems on my PC with this drive. Please help me! Should I format it to something else, get a new one, or something else? Please leave your suggestions below. Also, if you have an HD that works well, please leave it below,
P.S. All ports are free, except for the one with the HD in it. All that I have hooked up to my Late-2009 21.5" iMac is my wireless Apple keyboard, and my Magic Mouse. Nothing else hooked up to the computer AT ALL!

I am wondering why my MBP takes about 7-8 mins to copy 700 mb files from the external (Seagate FreeAgent pro 500 Gb) and of course, it takes about 1 hour to copy 7 Gb files.
However, this problem has occurred only copying file from external to my MBP, the transfer rate is fine when copying files from MBP to external
Note : I've already repair the disk by using disk utilities, but it doesn't help me at all.

How can I find out what my transfer rate is for ethernet and wireless. I switched over to Time Capsule and all N network?
Also, how can you tell if you have the gigabyte cable or the regular cat 5 cable?

When I arrive at my office and turn on my MB Air, it does not always connect to my wireless network, it sometimes connects to an un-secured wireless network locaterd somewhere else in the building. Is there a way to force Lion to always connect to a specfic network and ignore others?

I have used the disk for a number of years - all appeared to work fine - I am now backing up my data and only get Very slow transfer speed using firewire 800 - 2 hrs to transfer 1.36 Gb. Disk is connected to a Dual 1.8 Ghz Power PC G5 with firewire 800 - another d2 disk is connected to it with firewire 400 and I have just connected a Maxtor disk using firewire 400 to that. I have tried Updated the firmware (it did require it), tested the device alone on both 800 and 400 connections both slow. Restarted everything and used disk repair to check and repair the disks - repaired permissions on the startup disk.
Connected all the devices together again | LaCie 800 - LaCie 400 - and Maxtor 400. It sends data to all the other devices fast (~ 3 min for 1.6 Gb) through the LaCie 800 disk connection!, but does not send data to the LaCie 800 fast at all. Tested the other devices alone as well - they are all fast. Have also performed a TechTool Pro Ver 4 test on the the disk (Disk type ST325082 3A 232.89 Gb LaCie d2 External LUN0 revision 3.03) Passed the surface scan, disk controller and read write tests. Is the disk failing?

I did some experimenting this evening to assess data transfer rates to various storage items in my home network which uses a new Time Capsule as the router/hub.
Connected to the Time Capsule are the following:
- Mac Pro (GigE)
- Vista Machine (GigE)
- MBA (Wifi)
- Raptor Drive (USB 2)
- Time Capsule Drive (Internal)
Transferring a 650MB file between devices yielded the following results:
MP > Vista (GigE) = 288 Mbps
MP > MBA (5GHz) = 52 Mbps
MP > MBA (2.4GHz) = 43 Mbps
MP > Raptor (TC USB) = 38 Mbps
MP > TC Drive (Internal) = 38 Mbps
MBA (5GHz) > TC Drive (Internal) = 22 Mbps
It seems that transferring files to a USB drive or the internal drive on the Time Capsule is painfully slow. It took 2:20 to transfer the 650MB file to the Time Capsule over GigE vs. 0:20 seconds to another machine. What's worse, is that the data transfer speeds to the TC are a function of link speed, the slower your connection, the slower your transfer rates. It's not simply limited by some bottle-neck in the TC. It took 3:45 to transfer the same file to the TC from the MacBook Air over the 5GHz WiFi connection. When I complained about this the other day at the Apple store, the "Genius" said that it's due to QOS built into the router to ensure it doesn't kill my web browsing.

I've bought a powermac G5 (april, 2005) without an airport card. If I want I connect it wireless, what is the best and cheapest way to do it? Is it:
(A to buy an airport card with antenna
(B to buy an airport express station and connect it via Ethernet Or (C to buy an third party antenna to connect to the router So again: is it possible, what works the best, and what is the cheapest. NB. My wireless network is going via a time capsule. The router is on the first floor and my Mac is on the third. Powermac G5, dual core 2,3 MHz, 2.5 gb ram, 230 gb hard drive?

I have a 27 inch, mid 2011 imac. I bought it in March. It has started losing its wireless connection. The other issue is when it does connect it is very slow. I have a netgear modem, I dont think this is the issue cause the IPAD, and wireless laptop connect fine. I've also run a speed test, all wireless devices connect to 10Mbps and LAN devices connect up to 30 Mbps including the iMac when it is wired. Could this be an issue with the airport card? How would I know, how do I check? What should I do?Â

I have just got my 1Tb time capsule and there are a lot of confusing descriptions of how to connect it.
At the moment I have just selected "join existing wireless network" which is a ADSL 2.4ghz G Router that came with my internet package (Thompson TG585 v7).
Does this mean that all traffic goes via the ADSL Router and that I will not be using the 5ghz band when I back up so that all the data will follow a path like this and have slow data rates? :
MAC --2.4ghz--> ADSL Router --2.4ghz--> TC
or will I be communicating directly with the TC at 5ghz for backups and data transfer and 2.4ghz with the ADSL router for internet like this? :
MAC --5ghz--> TC
ADSL Router --2.4ghz--> MAC
If this is not a good setup, what setup would allow me to get the full speed to the time capsule and be connected to the internet.

I'm working in a home/home-office environment right now which was setup by someone else and I've noticed some odd network behavior when moving about the property. Looking at the setup, the relevant portion is: Cable modem - Airport Extreme - 10 port wired switch - 3x Airport Express in different areas of the house. The configuration of each device has the Extreme and all three Express devices set to "create a wireless network" with the network name the same for all four of them. I am not a networking expert but I would have thought that the Extreme should be set to be the "master" in a WDS network and the Express should each be set to participate in that WDS network. If they're all hosting their own wireless network with the same name and the coverage overlaps, how does a PC know which one it's using? Or maybe this doesn't matter. I just know that when we move from one room to another we frequently have to re-select the wireless network to establish connectivity.

OK, I asked this question previously, but not quite succinct enough, I think. I have a Pioneer home theater receiver that is network capable, but not wireless capable. I want to get this thing on my home network without having to purchase another device as my Mini resides no more than 36" away from it.So far, I have been able to get the receiver to connect to the internet through Internet Sharing on the Mini, but it remains blind to, and invisible to my wireless network. I simply want to connect the receiver to my Mini via ethernet cable and have it see and be seen on my wireless network. url...

I am trying to figure out how to automatically connect a MacBook to a network drive after connecting to the wireless network that the drive is connected to.
Here is the situation:
I back-up my wife's MacBook via Time Machine to an external hard drive that is connected to my Apple desktop. It works great! I even have her system setup to automatically mount the drive upon log-in. Unfortunately, after leaving our wireless signal and then coming back the time machine drive isn't automatically mounted since she isn't "logging back-in". Is there an automator script that can be built to automatically connect to drive X after connecting to wireless network Z?

I have a slow network issue. I'll try to make it as simple as possible.
1 MacBook Pro
1 Airport Extreme
1 Airport Express to Extend the Network
The network to my living room was slow, so I added the Express to extend the network. When connected through the Express, with a Time Machine backup, I'm getting about 500K/sec transfer speeds. When I move the laptop away from the Express and close to the Extreme, the network works much faster, about 5MB/sec. I don't understand why the network is so much slower when using the Airport Express as a network extender. Is the speed difference normally that much? If it's not supposed to be, is there anything I can do?

I'm extending my Airport Extreme router with an Airport Express. In the Airport Utility I am given these options:
"Extend a wireless network"
"Participate in a WDS network"
Which one should I choose and why?

The hard drive on my iMac is filling to capacity at an extremely accelerated rate. In order to have functionality, I had to delete some unnecessary files and used WhatSize to try and determine the culprit. When backing up my hard drive yesterday, Mail was showing to be 91G. The hard drive filled up again a few minutes later so I copied iTunes to an external drive for safe keeping freeing up 85G.
By this morning that was gone as well so I copied contents of Pictures over to external hard drive freeing up 189G. Mail is now up to 244G on my 500G hard drive. I rebooted at that point to see if that would stop the growth and it has currently, but it may start again. WhatSize says there are no duplicates. I am receiving and sending the same amount of mail that I usually do on a daily basis, so that is not the problem.
