Slow internet speeds on iMac running 10.10.3

Hey folks,
Hoping you can help me!
I have a late 2012 21.5" iMac running 10.10.3 and currently I've been getting very slow internet.
I've done some troubleshooting:
I've taken it to the Genius Bar and the airport card is fine.
I've reset dhcp lease which used to work but now no longer does.
Currently, my internet only gets normal speeds (about 100 Mbps down) when I delete my system config folder. Even after deleting it, however, it's only fine for a short period of time (usually a few hours) before it goes back to crawling speeds (usually the speed test ping test fails).
It's definitely not the hardware of the machine because it's picking up the wifi, it's not the router because the speeds are fine on my other devices and fine when I delete the system config folder, so I know it's software related. The issue does persist in a guest user or known good account so I know it's not user repeated.
I wanted to see if anyone else has any ideas to resolve the issue in the OS' current state prior to me just doing an erase and install.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Slow internet problem on my iMac solved by installing Google Chrome browser

I Fixed my iMac slow internet connection

I will share with you how I fixed my iMac slow internet connection and frequently lost connection. At first, I thought it was the Airport but then it wasn't the case. I also had a Dell laptop in the same basement and it was running as fast as I expected. Here are the steps:
1/ Open Airport link on the top right window > Open Network Preferences
2/
Click + to create new Network Name and Security, I chose WPA personal - less security than the WPA2- that is why it runs faster.
3/ Go mack to step 1 and select your new network name > Apply.
May iMac is now connecting to internet as fast as I would expected.
Good luck

My iMac internet connection is not faster but as fast as it used to be. I was using WPA2 and it was really good for a year and then I got disconnected or very slow. So I created the new network bearing the same old name but use WPA and did not delete the old one, some how everything is back to normal.

Slow internet connection via AirPort on MacBook running 10.5.7

The internet connection via AirPort on my MacBook is frustratingly slow, and I have no idea why.
I have an AirPort Extreme connected to a Virgin Media cable modem, a new iMac and a two year-old MacBook, both running 10.5.7. No problems at all with the wireless connection on the iMac - I get the full near-10Mbps download speed I'm paying for, despite the fact it's at the other end of the house. Not so on the MacBook, where I get barely 2Mb, even if I'm sat next to the router.
I've had other AirPort problems since the 10.5.6 update - notably one common to a lot of people on here, it seems, of the AirPort dropping the wireless connection every 2 mins. This was only 'fixed' by the fairly drastic workaround of essentially abandoning my user account and connecting via a different one.
For the slow internet problem, I've tried resetting the PRAM, turning off my cordless landline phone, changing the wireless channel - to no avail. I can't test the wired connection as my MacBook doesn't recognise my Ethernet port, it would seem, and hasn't for a long time.
Can anyone help? Thanks in advance.

I assume that you meant NVRAM as PRAM is not used with Intel-based Macs. Regardless, network settings are not stored here and resetting it won't really help. The fact that your MacBook is not recognizing the built-in Ethernet port is telling me that may have an issue with the system board ... that may be showing up as poor performance with the AirPort as well. I suggest that you take your MacBook in to your local Apple Store to have them take a look.

Does itunes 10.1 resolve the slow internet issues of itunes 10?

Hi guys,
when I installed iTunes 10 I experienced extremly slow internet connections and after looking through the forums, decided as some other users to revert back to iTunes 9. This did resolve my problems.
Now I note that iTunes has moved to 10.1 and I was wondering whether people who have installed it have any issues with their internet connection. I have an iMac 2.67 Quad - intel with OSX 10.6.5.
I would not want to go through all this again, I have been quite disappointed by this issue and the lack of support to it so I'd rather save the trouble and keep my opinion of Apple from any further damage !

i was just forced to install 10.1 b/c 8.21 (BEST itunes version ever - super fast, never crashed, etc) which worked flawlessly finally told me i had to upgrade b/c i could no longer see the store - it just stopped working. it's VERY painful to use 10.1 now, esp the store. this thread covers the same topic:
http://discussions.apple.com/thread.jspa?messageID=12743989#12743989
seems like it's on both windows and mac.

Very Slow Internet Lion (This one is for the "Apple Network Team")

hello,
i'm joão from Portugal, Europe.
a couple of weekends ago i've updated three macs to Lion.
2009 MacMini, 2007 White Macbook, 2010 iMac 21".
problems? only with the iMac.
no connection drops but slow slow slow very slow internet. wired, speedtest marked 15Mbps download. wireless? 1Mbps, 0,3Mbps, 3Mbps, very unstable.
with Snow Leopard everything was ok.
tried every solution from every site and finally got it working flawlessly.
tried clean install instead of update.
tried new dns servers.
tried disabling ipv6.
tried remove wifi interface then add it again.
tried service order.
tried PRAM, NVRAM, SMC, you name it, reset.
tried removing preferences folder.
tried different browsers -> same symptoms.
tried disable/enable airport.
tried 10.7.1, 10.7.2, combo, delta.
tried router's firmware update.
tried putting the computer closer to the router.
tried resetting the router, factory defaults.
tried changing router's channel.
tried disabling router's firewall.
tried watch router's event log, nothing suspicious.
tried disabling router's wep password.
tried pinging a site for a couple of minutes, 2% packet loss.
tried hundreds of pages and forums...
during this attempts, macmini and macbook showed very good wireless internet speed.
iMac? slow, slow, slow, slow, slow, like seeing gmail's loading screen for more than one minute...
again and again speedtest 1Mbps, 0,3Mbps, 1Mbps, 1Mbps, 0,3Mbps, 3Mbps.
discovered the pingtest utility in the same site and iMac's ping was grade C, grade F, grade D, with big values...mac mini and macbook were alwas grade B, with low pings (imagine 25ms on them vs. 138ms on the iMac).
i was fed up with the situation, every week tried and failed. iMac's owner was wanting to get his Lion money back and stick to Snow Leopard again. imagine recent Windows switchers thinking they went back to the same situations....
but then i found this website. and then realised macbook and macmini's wi-fi were both powered by a broadcom chipset. iMac's was powered by an Atheros chipset! did what the guy says on that site (replaced Lion's Atheros kernel driver by the one on Slow Leopard), and now everything is perfect, like on Snow Leopard. very good speed.
what a relief. thank you sir.
hope it can help you.
hope it reachs apple's network developers...this is not good, you can't fail on something so simple and essential as decent wifi quality...

humm...
i've clean installed one macbook (late 2008?) and one mac mini (early 2009) both with broadcom adapters and both of them were ok, after the install.
so, speedtest and pingtest are websites (speedtest.net and pingtest.net), both test your internet connection with the help of a 'local' server. it's useful, for instance, if you want see if two different computers connected to the same router have the same connection quality.
so if you can connect to some routers nicely and you have problems with your router, to me, it seems like you have some problems with the connection between your computer and the router.
an old router might bring you problems (there are some advices on the internet to change router's channel and so...), i would recommend to see if motorola has some sort of firmware update to your router. if you don't have complex router configurations, you might try to reset to factory defaults (search the manual). that, once, fixed a problem with a smc router and two macbooks (one, older, could connect easily, the other wouldn't connect to the router).
if that atheros driver trick, resolved your issue, that's strange
make sure broadcom isn't your ethernet adapter and not your wireless adapter
did you resetted your pram and smc? do you have Mac OS 10.7.2?
i hope you can figure that out.

not sure if that helps. but any ideas? because honestly it was a gift and I'm thinking of replacing it with a faster pc. It was a gift- and they offered this or a PC... and honestly- I like the mac (except this weird keyboard) but hate the slowness of internet. applications seem VERY fast. it's just the f-ing wireless. ugh. I have a wireless N server (belkin) which I now have only sending out G to help.
any thoughts appreciated. so sorry to bother you. hope you are well!

thoughts? please help!
p.s. is my airport card a wireless G or B?

There's no reason you should have slow connectivity with that Mac, but you haven't given any details about how your internet connection is set up, what you're using for DNS, etc. There are plenty of hints for how to fix your Internet connection in Leopard in these forums. You might start by manually entering an openDNS server to replace the one you're using and see if DNS resolution is the problem.

How to install Lion on Mac with slow internet connection.

My father's Mac mini has a slow internet connection. I always update it by taking the update packages that I download on my iMac to his machine. Will I be able to do that with 10.7 (Lion) when it is purchased/downloaded from the Mac App Store?

It seems that Apple's license terms will allow that across Macs that share the same App Store ID, but I doubt that's the case with you and your father. Physically the update package for Lion could be moved, but the licensing issues will have to be worked out. You're not the only person who's concerned with the issue of how to download a 4 GB file for Lion.

Extremely slow Internet over Airport, good speed with Ethernet

I've been using an airport extreme router (802.11n) for a while and recently I've noticed an incredible slow Internet over wifi. When I do a speed test it shows numbers like 200 kbps and I have a 10 mbps cable Internet connection. When I connect the ethernet from the modem it's perfect speed. Obviously Airport is slowing down my Internet connection. I tried resetting the Airport by pressing the reset button at the back, and it worked perfectly for a while. But after a few days it got back to slow Internet. Anybody have any idea?

I don't know if this will help anyone else, but I came across some changes (purely by experimentation) that may help. I hope so, at least...
I opened the Airport Utility and I swapped channels. The default is channel 6, but every other WiFi router defaults to this channel, too. I changed my Airport Extreme to use channel 3 (as well as my Airport Express), and now things are back to what I would have expected for an 802.11g connection.
I will offer the suggestion that those of you with the same Internet slow-down observed on their iMac G5's try swapping channels. If you have an expanded WiFi home network vis-a-vis an Airport Express, be sure to update it first before you update your Airport Extreme.
Best wishes and good luck!

Periodic slow internet

A friend who is running Lion on his 2011 iMac is encountering periodic very slow internet speeds, leading to timeouts on various sites. His speeds are normal for a while, then very slow, unable to connect, etc. If he leaves the system for a while, things get back to normal. This happens using Safari, Firefox and Mail. He has had calls to his ISP who insist everything is OK at their end. I checked his system while this was happening, but when I went to his network preferences, everything looked OK. But when we went back to his browser, it was then OK as well, so it may have been that the problem resolved itself by the time I got to the net preferences. Not sure what else to check. Suggestions?

Yep, I've powered down and restarted everything in
every possible order.
Among the 36 combinations of powering off and restarting
your 3 network actors, only one is good.
Start shuting down from the far end:
MacBook, AirPort, cable Modem
Restart from the provider end, and let everyone a full
minute to start up correctly:
cable modem, AirPort, MacBook.
The MBP works just fine on the
wired network at work.
Hence it doesn't look like a MacOS 10.4.8 problem.
Could you do some network testing with your MacBook
directly connected to your cable Modem?
Could you double check that you are not unfortunately
(but automatically) connected to the wireless network of
one of your neighbours?
If you want to be sure, make a network location where
only Ethernet may be used.

Yosemite install with slow internet

I have very slow internet at home, where my desktop iMac resides. Downloading a 5Gb file is impossible for ISP timeout reasons. For the Mavericks update I downloaded it on my MacBook using a friend's fast internet, saved the install file then transferred this to my iMac. The install worked fine.
For the Yosemite install can anyone tell me where the install file is downloaded to so I can repeat the above process?
Many thanks

I found the answer I needed on
http://osxdaily.com/2014/10/16/make-os-x-yosemite-boot-install-drive/
Also check out their earlier article on the actual downloading process, especially the tip on how to see the download progress bar in "purchases"

SLOW internet while streaming?? Anyone else have this problem??

I've looked everywhere and I can't seem to find anyone that has this problem:
I have an appleTV using 802.11N on a gigabit AEBS, with a core2duo macbook pro. Here's the funny part. It syncs beautifully fast without a hitch. No dropouts or anything. However, while it's syncing, all internet connectivity on my macbook pro is entirely cut off! Websites won't load, email won't send, ichat logs out, everything just goes down to a crawl, meanwhile the appletv syncs very fast. I've tested to make sure the internet connection isn't down by surfing on my iPhone and my mom's imac, and they both have fine internet connectivity while the appletv is syncing.
I've also tested the network speed to and from the airdisk. I assumed if it was my macbook pro's airport card that maybe when it goes really fast, it doesn't allow other traffic. Well, I moved big files back and forth through the airdisk at high speeds and internet seems fine. It's only when it's between the appletv and the macbook pro that the internet breaks...
I also tried it through an airport express with 802.11g and slower network speeds with the same result, so that rules out the base station.
Has anyone else had this problem? It's so frustrating because I have been forced to turn off appletv syncing entirely!

Well I know when syncing my iPhone, I have issues with internet speed on my Laptop (windows based) and also I cannot check email (fails to connect). Once syncing is done, mail works fine and I am browsing at full speed again.
I can only assume the sync process itself on the machine it is on is the issue. I figured it was just gonna be more so for Windows machines as iTunes on Windows is a huge resource hog when doing anything (downloading podcasts, syncing, etc). I just figured my slow internet access was more about iTunes bringing windows to a crawl during the sync and as for email assumed the sync process hoses what ports I can get out on.
Nice to see it messes with Mac users as well
Not sure why you have to turn off syncing entirely though. Won't it only do a sync if something changes? Mine doesn't sit there always sycning.
