Why the super slow internet connection on my MBP?

This falls into the category of FYI, or FWIW. I'm going to answer my question for the good of the community,
I suddenly noticed a significant reduction in my internet connection at home on my MacBookPro. According to speakeasy.net/speedtest I was getting over 11 Mbps down and 1.5 up before then suddenly I was down to 1 Mbps downloads and .25 uploads. I tried 3 browsers and an scp transfer via the terminal from my web server and all with the same results.
However, the mystery deepened when I tested other computers in the house and they were getting the original 11 Mbps. So, I took my computer downstairs next to the router and also got the original 11 Mbps. So, I went back upstairs, but instead of plugging in my old 23" Cinema display, I tested without. You know what happened, right? Yup, 11 Mbps. Plugged in the Cinema display and back down to 1 Mbps.
I have no idea what is going on, other something in the Cinema display is interferring with my wireless connection.

The same machine has worked on the same network in the past absolutely fine. A second machine has also been moved from London to this same network and is working fine. What coujld the problem be?
Many thanks

Super slow internet connection with time capsule.

Time Capsule wireless internate speed is insanely slow its super anoying, i have 15mb from comcast, and speedtest its scoring under 3.5mb down and 0.06mb up with a ping of 1025ms yees 1025ms this is unacceptable its almost impossible to use the internet please i need some help.

How can I get my time capsule to work like it used to?
Your TC is too old.. the power supply is on the edge of dying. The hard disk is probably also on its last legs..
The wireless card itself might be nearing EOL.. it is now 4years old.. or a bit more.. most stuff now is really not made to last more than 3years.. and the early TC tended to die in droves at 2years.
If you are prepared for some DIY.. you can fix it.

I have several suggestions. At various prices and difficulty.
I would replace the hard drive.. it is out of warranty and has run in a super hot environment that is outside its spec.. and still it refused to die.. at the very least run a full pass erase from the disk utility, and see if error come up or the drive is slow. It might be weak read areas of the drive.
Frankly .. unless you like the challenge, it is simply time for a new one.

Is there an solution for the wi-fi internet connectivity using a MBP?

I have frustration while trying to stay connected to the internet. I bought this MacBook Pro thinking the technology was far superior to other notebooks. Now I have realized the wireless connectivity issue is something tech support has been unable to solve. This is a basic option on most new notebooks and none of the other brands in my home have this issue. Is there any help for me or am I stuck?

Can you connect to public wifi? Have you tried updating your router's firmware? Have you tried using a different channel? What security are you using? What model router do you have?
I don't have and I am not aware of any systemic wifi connectivety issue.

How to download adobe products without adobe download manager. I am on the slow internet connection

how to download adobe products(e.g lightroom) without adobe download manager. I am on the slow internet connection. The adobe download manager ask me that download will finish after 24 hours.

You can get all the download links to software updates back many years by going to:
www.adobe.com/downloads/updates/ and choosing your software product in the dropdown list at the top and clicking Go. This should lead to a page of updates going back in time. It doesn’t have the .0 versions because those require payment, but the .1-.n free updates to the .0 version s are there.
You can also get beta software downloads by going to:

After the download, hold down the Shift key when you click Update in iTunes, and you'll be prompted to locate the downloaded firmware file.

Can I use an Airport as a wireless modem, and will it improve a slow internet connection (from the source)

Living on a acerage outside of the city, we have a weak internet signal. It takes days to download a movie from iTunes. Will using the new Airport actually improve our internet, or are we limited to the poor incoming internet connection?
I'm not very skilled in network stuff, so apologies if this question is really stupid.
Thanks

There is no modem in the Airport router. You cannot use it alone. You must have a modem and the speed will be set by the type of broadband, and factors like distance.
Ring your ISP and ask if there is any way to get a faster connection.
Often 3G/4G wireless will be faster than adsl but will cost many times more.

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.

My 2007 mac pro has a slow internet connection with lion

Hi:
I've been dealing with a severely slow internet connection with my 2007 mac pro - dual quad core. I have os 10.7.3. I use wifi.
Typically, I'll experience difficulty loading websites completely. Certain sites have a 90% failure rate to load most elements. Other sites operate quickly from time to time. Often, a site will simply fail to load at all. My cable company cannot find anything wrong with my connection and other, newer devices don't have a problem loading sites. It seems the issue is most likely related to my computer.
Interestingly, I can usually "jump-start" the connection by turning my wifi connection off and on and this will (temporarily) allow me to get an image or video to download.
Any ideas?
Thank you for your time.

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.

Slower internet connection when connection wireless network

Currently using a Linksys WRT54GL wireless broadband (firmware v4.30.5) router in conjunction with a Thomson Speedtouch 546i ADSL router (ISP provided).
My problem is that when I connect to the internet over the wireless network I experience a much slower internet connection in comparison with when I use a tp-cable.
Tested with various online "speed-tests" (I know they are not to be trusted, but they do give a basis for comparison):
Over wireless network : ca.6000kbits/sec.
Direct cable from pc to router (tested on both routers):12-13000kbits/sec.
Hope anyone has any idea what the problem may be, and any help is greatly appreciated.

Change the beacon to 50 ....and reduce the RTS and the fragmentation by 40 each.....these options are found under the advanced wireless settings...
Also make sure that u have the latest drivers installed for the Wireless NIC.

If you have an Airport Extreme router and a slow Internet connection ...

I know that Internet connection speeds are extremely variable, but I wanted to share this post for anyone having performance problems (very slow Internet connection speeds) while using an Airport Extreme router. This may or may not help you, but it might help someone.
I have a RoadRunner Turbo account, and I was experiencing consistently slow Internet download speeds (an average of only about 300KB/sec). However, when I bypassed my router and connected my Mac directly to the Time Warner modem my download speeds were 6 to 8 times faster (up to about 2MB/sec).
After weeks of tinkering and reading Apple documents I discovered that my Airport Extreme router had an improper setting. That setting is found under: Manual Setup -> Internet -> Internet Connection -> Ethernet WAN Port. When I was experiencing the very slow speeds, my Ethernet WAN Port setting was: '100 Mbps/Full Duplex.' To fix the problem I simply changed this to 'Automatic (Default).'
This one change resulted in a huge, positive performance boost for me. I hope this post helps other people.

You use an App like Filebrowser. Details here:

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.

IMail 5.2: How do I optimize it for use on a slow internet connection?

Hi there,
I recently upgraded to Lion OS X v 10.7.3, and i like iMail 5.2 when I work from my office or home.
BUT, when I am working in the field I often have access to only glacially slow internet via an internet modem, and iMail takes FOREVER to download my messages. Way longer than my pre Lion version of iMail.
Is there a way to optimize iMail 5.2 in order to optimize for slow internet connections? For instance, to partially retrieve large messages? Or to somehow deactivate all the synchronizing and other Activity that goes on in the background?
Many thanks,
Hoyt

Use a web based email account like GMail or HushMail, because they are a website and people access their emails from many different machines (phones, computers, slow or fast connections) the site can optimize things better than a dumb mail server.
It's possible to auto-forward a copy of your present email accounts to have them on the web based accounts too, don't know exactly how to go about it, but many people elsewhere also have the same desire so it's obvious something like that is being used.
