Wifi Ac iMac 2013 showing connection speed 1g/s
Connected over strong-signal Wifi Ac. Network utility shows the link speed to be 1 g/s. Is that 866 M/s rounded? If I switch to the other 2.5 GHz network, the speed indicated drops to 144 M/s. No issue with coverage /signal/hardware. To me it looks like Network Utility is out of date.
Thanks but the reason for mentioning the other network was that Network Utility indicates the connected speed at least for Wifi N. However for Wifi AC, it is indicating a speed i.e. 1 G/s that is well above the spec of 866 M/s. My question is does 1 g/s on NU = 866? Is there another utility that supports Wifi AC?

My Lacie Big Extreme Hard drive does not show connection speed
*My Concern*
Hi I have a Lacie Big Extreme Hard drive, which although works fine is not showing its connection, shows up in the system profiler as 'Connection Speed Unknown'. -Should I be worried? I have other drives connected to my G5 Dual 2 gig machine and no problem their they all show their connection speeds.
*Other Firewire 'Unknown Speed connection' related Problem*
I had a DVD LaCie Dual layer portable Firewire drive which recently suffered from the same problem and I had to send it back. This was due to it slowly developing a fault of not being able to burn dual layer disks properly.
*What I have done to try and remedy the situation.*
I have been able to do the following but I am afraid with no change in the system Profiler;-
1 Trashed the whole system and rebuild
2 repair my permissions
3 empty out all my caches with OnyX (third party app) version 1.8.5
4 Disconnected all drives and reconnected them one by one to see if there are any anomalies within the system
5 switched my G5 off removed the plug from the wall waited 30 sec for it to reset itself this was the 1st attempt. On my 2nd attempt I then cold booted the machine and reset Pram settings
6 used Tech Tools Pro 4 version 4.1.2
7. Replaced Power supply of the offending unit (didn't have to but I wanted to be safe and eliminate this fronm the equation.
9.tried changing around the order in the chain to which the drives were connected to the G5but alas no joy!
Summery
So my concern is if a device which is Firewire shows up in the system profiler as connection speed unknown should I begin to worry even though it appears to be functioning.
Thank you ahead of time for any help on this matter
*Supporting evidence*
Please see below a shot of my System profiler so you can see what I mean:-
*(Important Note)*
The Lacie Big disk has 800/400 Firewire connection speeds I have connected it straight to my G5s firewire 800 port then daisy chained the LaCie's via its other 800 port to the two other 800 Firewire Hard drives.
When the LaCie DVD DL drive was connected, I connected it straight to the 400 firewire port. As it needed direct access to the G5 for it to function optimally.

File System: HFS+Hi BDAqua - thanks a lot for replying - really appreciate your help. I was using Time machine to back up on the old lacie drives that I have - I just backed up on both lacies and they backed up faster for some reason but that might have been because they were very small back ups as I did full back ups on Tuesday night - this is the info under the USB section > hardware > about my mac - it didn't show the speed like the example you gave me though but it still backed none the less :

I also got a reply back from WD on the hard drive and they said the following - exactly the same as you about it being a problem with the power supplied hence why the disk won't mount - so you were spot on - so I'm thinking I should go ahead and get the newertech 7 USB port 4 amps as you suggested - let me know what you think and then I'll just order it - and thank you - really do appreciate your help on this - thanks Jayas
Dear Jayas
Thank you for contacting Western Digital Customer Service and Support. My name is James.
If the drive is working fine on one system but failing on another especially with the "clicking" sound this is an issue with the system not being able to supply enough power to power the device.
These devices require power from the machine to make them operate if there isn't enough power supplied the drive will fail to work. This is why you are having no issues with one system but are on another. -
Linksys e2500 connection speed
I have both a linksys e1200 and e2500. My internet speeds are rated at 50Mbps. When hardwired I get about 55Mbps. But when I use wireless, even right beside the router I can only get about 20Mbps down. My wireless deviced show connection speed of 55-58Mbps but when I do a speedtest I only get 20Mbps or so, the same with my desktop. I have tried with security and without, and tried a few other options. What is keeping my Galaxy S3, Note 10.1, Asus TF300 Iphone4s and desktop from getting my full speed? I know my tablets and GS3 should be able to as well as my desktop.
Any Ideas? Im out of options my last step was to buy the e2500 but it didn't help!
Thanks!
JamesYour link/network speed is different from your internet speed. You adapter can go up to 55-58Mbps for the wireless network connection but your wireless internet speed will only be around 20Mbps. Sabretooth is correct. This is about the max that you can get for the internet speed. If your wireless link speed will go up to around 130Mbps, then you will probably see an increase in your internet speed. You can play with the wireless channel of the router and make sure to use wpa2 personal for the wireless security. Check and see if your link speed will increase. If not, then that's what your adapter can only cater to.

I have a New Mac Pro Tower connected to an AX b/g compatible WDS network and it gets 10k kbps download speeds.
The Problem is my iMac G5 connected to the same network has an extremely slow download speed of 583 kbps?
Anyone have a clue as to why iMac's internet connection speed is so much slower?I have had the same problem since november 2007:
I connected an old airport extreme basestation and a brand new one through WDS.
it took me a while getting the WDS to be faultless. (the encryption caused issues). So with both in WEP mode I lost the last error messages and both devices tell me all is fine, but it isn't.
I have NO access to the Internet via the router. I have no access to anything on the other side. The same goes when I hoop up in the other side then I have no access to devices (IP-Cam, printers, routers, Mac's, PC's...).
What is wrong with WDS?
I removed the old aiport extreme and used only a TimeCapsule and the new Airport Extreme. Nothing changed.
The Internet is extremely slow and gives time outs.
Finally I pulled a 60m cable to the TimeCapsule -
Help : very slow connection speed with AEBS and iMac
I connect to the internet using my newly purchased AEBS. I have a MacBook and an 24" iMac ( purchased in Nov 2007). My iMac showed very slow connecting speed of <1 MB/s download; with my MacBook placed just 1 foot from my iMac, the MacBook showed an amazing download speed of 20MB/s. If i connect the iMac to the AEBS using ethernet cable, it can get a very high speed.
So, where is the problem??
I am new to wireless, please help. I use iMac more than my MacBook at home.
Actually, i did not touch the any of the advance setting of the AEBS.You know, I am experiencing the same problem. My wife's PC and iPhone are blazing fast, but my MacBook is accessing the internet at about dial-up speeds. Very frustrating and I haven't yet found the culprit.
Anyone??? -
Remote App on iPad connects but drops after about 20 mins. Need to turn off wait about 1 minute, then turn on wifi on iMac before it can reconnect. Need some help please.
Already gone through troubleshooting guide a zillion times. Thanks.This worked for me... A little time consuming but once you get rolling it goes GREAT... Thanks....
I got my artwork and saved it to my Desktop
Opened up Microsoft Paint and clicked on "File" and "Open" and found it to get it on the screen to resize it
Clicked "resize" and a box for changing it opened up
Checked the box "Pixels" and "Unchecked maintain aspect ratio"
Set Horizontal for 640 and Vertical for 480
Clicked on "OK" and went back to "File" and did a "Save As" and chose JPEG Picture
It came up "File Already Existed" and clicked "OK" (really did not care about the original artwork I found because wrong size)
Went to iTunes and on the movie right clicked on "Get Info", clicked on "Details", then "Artwork"
Go to the little box on the top left that shows your old artwork and click on it to get the little blue border to appear around it and hit "Delete" to make it gone
Click on "Add Artwork" and find it where you put the one from above on your Desktop and hit "Open" and OK and your new artwork is now there and all good.
Sounds like a lot of steps to follow but after around 5 or so you will fly through it. This worked perfect on my iPhone 6 Plus and I have artwork on my Home Videos now. -
my imac will not connect to wifi what so ever. i have tried 3 different routers and all my other apple devices work fine. when i take it to the genius bar it seems to work with apples instore wifi. thus leading the "geniuses" to say nothing is wrong.
Back up all data before making any changes.
Step 1
Take all the applicable steps in this support article.
Step 2
If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.
From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.
If the application called "Bluetooth Setup Assistant" is running, quit it.
Step 4
This step will erase all your settings in the Network preference pane. Make a note of them before you begin, and recreate them afterwards. It may be helpful to take screenshots of the preference pane.
Triple-click the line below on this page to select it:
/Library/Preferences/SystemConfiguration
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Step 5
Reset the System Management Controller.
Step 6
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
*An SSD doesn't need to be zeroed. -
How does this happen: The picture of recent apps you get when double clicking the home button showed in Settings-Wifi that I had been connected to a network I have not been near for two months. Its not a recent "image" of Settings-Wifi. Can anyone explain?
Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M. -
My iMac won't connect to my wireless shaw modem. It shows as connected but not to the internet?
It was all working fine then I started my computer today and it would no longer connect to my shaw wireless modem. It now says it is connected to the wifi but not the internet. HELP! I need to be able to use the internet on my iMac.
Thanks!hockeyman68, Welcome to the discussion area!
If Safari is still able to browse web pages, your iMac is still connected to the internet.
Perhaps you should visit the iChat discussion area... and provide a lot more detail on what you are experiencing. -
Ipad 4 wifi shows connected but times out to servers?

Have you tried restoring the iOS software?

If nothing else has worked in the support article, this would be your next step. If that doesn't work, a trip to the Apple Store would be in order. If they can't resolve the issue, your iPad is still under warranty and should be eligible for a replacement. -
Has anybody solved the slow wireless connections speeds of the new Imacs
I have just purchased the new imac...and was made aware of the disastrous connections speeds using wireless.. Does anybody know if apple have come up with a solution...or are they just not dealing with the problem?
I am a brand new Mac user with a new 24 inch iMac purchase. Macs are supposed to be hassle free right? Right. No question I was about ready to throw it out the window because the wireless connection to the expensive AP base station was, oh, 100x slower than my Dell laptop side by side about 1 foot away. Nothing changed even if I connected directly to the AP using an ethernet cable. My connection consists of an Actiontec DSL gateway connected directly to my AP extreme that allows wireless to my PC laptop as well as my new iMac. Hours and hours go by until I find this help link on Mac Orchard Forums:

my wifi is showing connected but i am not getting internet access.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
• Launch Settings app
• Tap on Wi-Fi
• Tap on the blue arrow of the Wi-Fi network that you connect to from the list
• In the window that opens, tap on the Renew Lease button
