Extremely slow internet via wifi

Hi there!
I bought some days ago a MacBook Air (the low end model, 1,6GHz) in the USA. Now, in Italy, I can connect it to my wifi, ADSL belkin modem+ wireless router 802.11.g, but the speed is prohibitively slow! Indeed, I measured it with a simple speedtest (Internetfrog) and it consistently gives me 16 kbps . At the same time, my other computer (Windows PC), measured with the same tool, has a speed of 1,14Mbps, as it used to have...
There must be something wrong with the Mac or the connection!
Since I am new in the family, can somebody out there help me get a smooth landing in the Mac world?
Many thanks in advance

I have had the same problem with my wireless lan connection of my brand new macbook.
The connection was terrrible slow.
For me it works, so perhaps this will work for you, too???
disconnect from your network by turning off AirPort or unplugging your ethernet cable.
trash the following folder (from the global /Library, not your own ~/Library in your home directory): /Library/Preferences/SystemConfiguration
if required: enter your admin password
restart your pc
turn on your Airport card and enter your network settings
I've found the solution in discussion for macbooks, so here is the original post:

So let me know, if it works for you....

Slow internet via wifi

i'm posting again about the slow airport where the webpages start to load and pause for 10 seconds then continue to load VERY slowly.
i called apple, they said it's my card or the router. i brought it to the store and it worked fine, so i'm assuming it's my router.. but what is wrong with my router?
it works well with everyother computer in the house, even a powerbook.
why is it JUST my MBP that has insanely slow internet via wifi?
i have a netgear wgr614v3..
should i buy a new router just because my MBP doesn't work good with it?
thanks!

That is what I ended up doing. Though in my case it was not just my computer but my wifes Toshiba as well. They both have the Atheros based cards. I have seen reports regarding issues with the Atheros cards and certain D-Link, Linksys and Netgear routers though the one I had as a Belkin Pre-N.
The issue I had was in using the WPA security. It worked fine with WEP but had the symptoms you describe with WPA.
I recent replaced it with a Netgear RangeMax WPN824 v2 and they both appear to be working fine so far. My Dell notebook which is not Atheros based had no problems with either router.

Extremely slow internet using wifi.

Hi guys,
First post here so be gentle.
After a week or so of using Arch I started noticing some strange things happening so far:
- Pacman's package list downloading from the repos happens at regular speed (around 700Kb/s), then followed by a 30 secs lag between each package download, which starts at normal speed, but then come down to around 2Kb/s then I get an Address Record error, which terminates the download.
- first ping to google is fine, then any ping after either get a 'host unknown' error or ping takes around 9Kms.
- another strange behavior that happens when pinging is that the wireless connection start at a bit-rate of 1Mb/s (according to iwconfig), then every time I ping google the bit-rate jumps (1Mb/s -> 12Mb/s -> 24Mb/s -> 54Mb/s -> 81Mb/s).
- can't load any websites (google takes around 5min to load, most other sites I just get a timed out error)
So my config is as follows:
- Intel Centerino Ultimate-N 6300
- connected using NetworkManager (but while connected with wicd the problem still occurs).
- running gnome 3.
- the router is Edimax 6524n
So far, I've checked resovle.conf (which only states my router ip address, which is fine because it serves as my DNS server), my hosts file (which is configured according to the tutorial in ArchWiki) and I've disabled the ipv6 module.
I've asked in several forums so far but with not much success, so i'm really hoping someone can solve it for me.
Thanks in advance!
PS: in one of the forums i asked someone asked me to post the output of dmesg | grep -i iwlagn, so here it is:
pastebin.com/Pmhi6swv
PS2: This problem does not occur in any of the Windows machines that are connected to the wireless network nor does it happen when this exact machine runs Windows; so the problem is definitely in Linux

I'm kind of having a similar problem. Ever since upgrading to 2.6.39 my wifi is extremely slow. It connects in g mode according to iwconfig and other network analyzing programs. I have iwl3945. The problem is. First it connects to wifi network(which takes about 30secs to successfully complete a connection request) it works great and I'm measuring 25Mbit(which is my internet connection speed) on speedtest.net. But after some minutes my speed drops to around 100KB/s and has a slight fluctuation, not quite constant. Even the upload is bigger than the download speed. If I disconnect the wifi, reload the kernel module and reconnect, then it works again for 1-2 minutes at full speed, then the speed drops again.

Any suggestions, or ideas would be very helpful. Thank you.
btw. I use NetworkManager and kernel 2.6.39

Extremely slow internet via ethernet with Mavericks upgrade

I recently upgraded my mac-mini to mavericks from snow-leopard. Ever since then, my internet connection has basically ground to a halt, and since much of my work is based off access to files on a server via a web-portal, my work flow has basically ground to a halt. I've talked with IT here at the office and the network connection is functionining fine, ping speeds are proper and I'm not dropping packets or having collisions or anything like that.
All of the issues I see discussed here revolve around the wifi/bluetooth conflict issue, and since I'm not connecting via wifi to anything, this doesn't help me at all. Is it possible I have a corrupted install that's causing this? Or are there something I could do in my network settings or elsewhere to alleviate this problem?

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, or if a firmware password is set, or if the startup volume is a Fusion Drive or 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.

OS X Yosemite 10.10.1 slow internet via wifi

I'm posting this in the hopes that Apple will fix soon. I have a 27inch iMac late 2012. All was fine with Mavericks. After upgrading to Yosemite my internet is slow via my wifi. Yosemite 10.10.1 did not improve anything. iPad and iPhone 6 maintain normal internet speeds with same wifi. I've tried various solutions that have been posted by others and recommended by Apple support. No improvement. When accessing a page on internet, Safari browser blue line in address field goes about 1/4 of the way across and then pauses...sometimes up to 10 seconds...before continuing and rendering the page. I do not lose wifi connection, as some people report, it's just much slower than it was with Mavericks. Apple, please fix ASAP!!

I have a new MacPro which was purchased with Mavericks and all ran very well. Shortly after "upgrade" to Yosemite my attempts to connect to the internet are as you described but with an ethernet connection. This is not just Safari but also Mail too.
All my other devices ( iPhone 4; iPad 2; old MacPro 1.1 and old macbook ,both with 10.7.5,) will connect to the internet as they should whilst the New MacPro just hangs. However my Macbook Pro which was also purchased with Mavericks and subsequently "upgraded" to Yosemite connects to the internet with no real problems via wifi. Both the New MacPro and Macbook Pro are running through the same network arrangement as are all the other devices mentioned.
I find that when the New MacPro is hanging that if I use my iPhone or iPad to connect to mail for example it seems to kick start the New MacPro and it soon after makes connection.

Extremely Slow Internet via PC Card 10/100 adapter (RealTek 8139)

I need to use a 10/100 PC Card adapter for internet access and it used to function perfectly under 10.4, but I recently upgraded to 10.5.1 and the speed is close to dial-up (approx 1/10th that which I was used to getting).
I have seen several posts for this issue, but never with the PC Card. Is there a separate fix available?

From what I understand the manufacturer only needed a driver for 10.2 and older versions of Mac OS. 10.3 and 10.4 worked with no supplemental drivers. There is no mention of 10.5 on the manufacturers web site.
To be honest, since Apple has been including ethernet support as a built-in, there is a lack of 3rd party support for these expansion cards on the Mac OS. I doubt that the OEM will desire to invest time in fixing whatever broke under 10.5.

AirPort Extreme standalone conflicting with internet via WiFi

I have just purchased an AirPort Extreme to connect my hard drives (via a powered USB hub) to my MacBook Pro.
I can only select either the internet via WiFi or the AirPort Extreme.
How can I connect to my devices as well as the internet without having the internet feeding into the base station?

If the AirPort base model has an external antenna port, you could maybe
extend the range of that unit; or perhaps use it to expand the wi-fi network
already provided by your wi-fi broadband unit.
The original Airport cards were 802.11/b standard and are probably limited
to some extent if your broadband wi-fi unit is having to send both 802.11/g
and 802.11/b signals. If you don't need the newer protocol /g you may be
able to stick to the earlier and directly more compatible wi-fi your older Macs
use, by using the Airport base station and check into its configuration; and
put that unit in line via ethernet to give it a signal to broadcast, to see.
Also, some models of Airport (Extreme) Base Station, and maybe the other
earlier white orb spaceship-like models, can be used to expand a network.
The AirPort Admin Utility and administering the AirPort base station by
Ethernet to set it up, may allow some configurations otherwise unattainable.
A wireless bridge may be possible. I did a google/mac search
& found a few things; probably too many to get one pure reply.
[ general "expanding AirPort Extreme network" search ]
-This kind of search now gets you the newest AEBS 802.11/n device.-
Also: [ expanding AirPort network ] gives a few other results.
I know you can use two AirPort base stations to expand a wi-fi network;
but am not sure what it would take to make your broadband wi-fi unit
give you a greater local range. An Ethernet cable of some limited length
could put the older AirPort base station closer to the place you choose
to use those Macs which now have virtually no wi-fi signal.
What Mac computer models are those "older" ones you refer to? There
may be other options, but I am not clearly focused on this topic now.
I see two iMac G3's in your post... that's probably them, huh?!

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!

My macbook pro cannot connect to internet via wifi

I have a Macbook Pro 2010 OS X 10.8.3. I cannot connect to internet via wifi (Air por). My Macbook Pro does not recognize my network and when I select it from the list of network it asks for my network password. when I type in my password a dialog box gives me timeout error. Please could anyone help me. I am using ethernet for my connection at the moment. Do I need to reset my macbookpro? if yes, what will happen to my applications and operating system (mountain lion)?

When you use the Airport utility what happens?

Wi-Fi Setup Considerations
Things to consider before you begin
Start with a plan for the physical layout. Depending on whether you have an existing Wi-Fi network, or if you are using your AirPort Express as a standalone Wi-Fi device, there are several options available for you to choose from.
When using Ethernet, Cat6 cable is recommended.
The layout you choose should take into account environmental factors such as physical access, location, range, radio frequency interference, etc.
You will need to consider what AirPort Utility settings to adopt.
You will need to know whether you are using an AirPort Express (802.11b/g) or an AirPort Express (802.11a/b/g/n).
If you will be using more than one Wi-Fi base station, it may be helpful to read the article Extending the range of your wireless network by adding additional Wi-Fi base stations.

Windows 7 Ultimate (64-Bit) fresh install, only WLAN and video driver installed but EXTREMELY slow internet connection...

I recently checked my internet connection on my Asus G53SW and found that it was extremely slow on both the LAN and WLAN connections. I checked with a different laptop (old HP Pavilion) and I get a steady 74mbps+ connection using the same LAN cable and
also with the WLAN connection. My ISP has checked their side and everything is fine.
To try and resolve the issue I tried uninstalling, disabling and tweaking various software and even tried safe mode with networking, all to no avail. I then decided to do a complete fresh install this afternoon. I have installed Windows 7 Ultimate (64 bit)
successfully onto my SSD and everything went smoothly. I have now only installed Nvidia video drivers and the (only) WLAN driver from the Asus support site.
My WLAN connection remains incredibly slow (amost half what it is on the HP and my MacBook Pro). Clearly this is an issue with either the Asus laptop or Windows but I don't know how to proceed in order to eliminate which it could be other than to try a different
o/s to W7-Ult.
Can anyone help who knows more about this than me? Perhaps someone who has had a similar or the same problem because this is giving me a severe headache!
Thanks in advance to all and for any advice.

Thank you for responding. As I stated in my original post the reason I went through this process was because of an extremely slow internet connection from both the WLAN and LAN connections on my G53SW. At that time I had all of the correct drivers on the
machine. Whilst I would agree that with the machine only having a video and WLAN driver it may well not be working 'optimally', the rationale for doing this was to get the machine working with the minimum of processes to show that it was not anti-virsu software,
Steam or the like causing interference.
I have changed out both of the HDDs this evening (a primary SSD and a secondary 1Tb HDD) for a clean hybrid 1Tb Seagate drive. Once I have installed all of the Asus drivers (and nothing else) I will try the speed test again and report back.
I can now report that with a fresh install of Windows 7 Ultimate SP1 and ONLY Asus drivers as supplied the issue remains. On a connection where I should see around 75mbps I am actually getting around 18mbps, sometimes considerably slower. This only affects
my Asus machine.

I am unable to connect my ipad to the internet via wifi, when asked for my password I get message "unable toI ge join network" however my laptop is able to access the internet using similar procedures and in the same physical location.?

What router are you using? make/model/version
What security type are you using? If it is WEP then symbolic (non hex) keys may be converted to hex in different ways by different operating systems. Is your laptop a Windows PC?
If you are using WEP then drop it and move to WPA2. WEP has been deprecated by the WiFi alliance since 2004 as insecure (it can be hacked in seconds).

Unable to connect to internet via wifi

I have had this problem ever since I received my preordered Dinc. I can successfully connect to the internet via wifi anywhere but at my place of employment (very frustrating). The Dinc sees and connects to the wifi but when I open the browser the following pop up window appears:
“Security warning
There are problems with the security certificate for this site.
This certificate is not from a trusted authority”
I then have a choice to continue, view certificate, or cancel. When I view the certificate it states the organization, The Go Daddy Group Inc, unit, Go Daddy Class 2 Certification Authority and validity:
VZ tech support stated that they never heard of it and recommended that I call HTC.
HTC said that this is a common problem and that Go Daddy uses a variable wild card for their SSL. The conversation ended when they said that there is nothing that can be done.
I finally contacted Go Daddy who said that they need the account number without that there is nothing that they can do.
Laptops, Iphones, and other cell phones can get on the internet.
My questions to this board are:
Has anyone else had this issue?
Does anyone know of a fix?
Who is responsible for the fix VZ or HTC?
Do you think that when (ever) the OTA update to Froyo will fix this?
Thanks to all

I'd talk to your IT dept at work.

Problems accessing the internet via wifi

I'm not able to access internet via wifi but am connected to my wifi network.
No problems when using 3G
I guess it is a dns problem?
when i check the wifi settings IP address and subnet mask
have details but is blank for router, dns and search domains.
What details should I input there?
Would it mess anything up if I used the same settings that my iphone uses?
I know wifi is ok because I can download books to my ipad with stanza using wifi.
Sorry don't know too much about this sort of thing

Yes, this would be determined by the size of the IP pool allocated on your time capsule router. Ordinarily this should be large enough by default to accommodate the number of devices you have.
Not sure where to check
"If DHCP is not working for you then you should check to see if your router is set to do DHCP and that MAC address filtering is not turned on"
*First, please note that if you aren't really familiar with network setup you should probably give Apple support a call and they can walk you through this.* See: http://www.apple.com/support/expert/
You can access your Time Capsule router using the Airport Utility which is found in the Applications/Utilities folder on your Macbook Pro. If you use this utility you can see how your router is setup. Post what you see here, i.e., Network name, radio mode, channel, Security password protection (WPA2 personal is best), etc. Of course, don't post any passwords.
Don't forget to check that the IP Address selector in your iPad WiFi setting for your network (which can be DHCP, BootP or Static) is set to DHCP.
I will turn Time capsule off for a while to try.
At this point it might also be a good idea to also go to Settings > General > Reset on your iPad and select "Reset Network Settings".

I have a problem in connecting to internet via WiFi.

I have a problem in connecting to internet via WiFi. This week I received my new "iPhone 6 and 6 plus". Problem is the new phones doesn't connect to internet via my home WiFi while I don't have any problem on my other devices. The phones connect to WiFi but most of Apps can't connect to internet.

Hi vpouya,
If you are having an issue with connecting to the Internet from your iPhones via Wi-Fi, I would suggest that you troubleshoot using the steps in this article -
