Airport download speeds slow when extending display to LCD

When I connect my Macbook using the mini display to DVI, DVI to HDMI adapter to my LCD TV, my download speeds pretty much fall off to nothing. When I disconnect the display adapter, the connection resumes. Any ideas?

Was wondering if you can elaborate on your response and perhaps help me? I apologize if I have missed this topic covered elsewhere.
I am using a N-capable Time Capsule and an older model G-speed airport express. My biggest issue is that my wireless speeds are 1.5 download and 1.9 upload when in fact my cable modem pumps out 15! In reading your posts I see that my network is likely dropped down to G due to my old express, and in fact my computer may be running of a spliced version of that if using WDS settings?
I think i'll end up calling apple support at some point but was curious if you can go over the facts of using N and G together, and if i can have my macbook pro speak to my N network only and my iphone 3G speak to G airport express only?
Last piece of info is I use the airport express for my music.... not sure if this means they must be WDS or not? I'm just looking to get my N devices as fast as possible while continuing to use my G express. If you tell me i need to upgrade to a N express I can live with it.... but if i can avoid the $100 and work with what i have...all the better!
Thanks in advance,

Airport download speed SLOW!

I am having what I have found to be a common issue (from searching Mac forums)with Airport speeds on my Mac Pro. I am getting very slow download speeds with on my Airport Express network, however my upload speed is normal. I have 2 Mac laptops on the network, both receiving 2.5 to 2.8 mbps download speeds while the Mac Pro, 3 feet from the Airport, downloads between 300 and 1000 kbps. All computers are configured the same, and everything is working fine on the network, including the 2 laptops and an Xbox 360. Only the Mac Pro is experiencing problems.
Upon first hooking up the computer, it worked fine, but later in the day developed a problem with connecting to the network. A clean re-install fixed the problem, however, after a week or so, I am having the speed issue. While I was once able to stream music and video and use wireless printing from the Mac Pro, it is now too slow.
Furthermore, when selecting the airport icon from the menu bar, the computer hangs for a couple of seconds before opening the menu. Is there a solution to this problem? I have been unable to find a solution on the internet, yet I have read of several similar and identical problems with Intel-Macs.

After a lengthy walk-through with an Apple Tech, we were able to fix the problem by power-cycling the Airport and Modem, erasing my network (in the Airport settings in Network Preferences) on the Mac Pro and re-adding it to the Preferred Networks, removing all cables from the Mac Pro, waiting 20 seconds, reattaching cables and then zapping the PRAM (apple, option, P, R) after the chime on start-up. Seems to be working fine now, hope it lasts!

Airport express very slow when extending Time Capsule

I'm trying to help my father solve a networking problem.
For the past several years, I had him using an airport base station and (2) Airport Express units as extenders.
He was using a circa 2004 Powerbook G4 17" and a MacPro Dual Core tower unit.
I finally got him to upgrade the Powerbook to a the new Macbook Pro i7. With the older computer out of the loop, I also upgraded him to Time Capsule.
Everything is installed and running now. However, the network speed in portions of the house where the Express is supplying the signal is very slow. A test on the laptop with DSL Reports gave an average upload speed of about 200.
When I move the laptop right next to the Time Capsule, I got a DSL Report speed of 22,000!
This issue is not laptop specific (it shows up more on the MacPro because it's in a back room), but seems directly related to the speed passing through the Airport Express.
What did I do wrong or do the Express units need to be upgraded (they are on firmware 6.3)?
Thanks!

Airport Express EXTREMELY Slow when extending Aiport Extreme

So I have an airport Express hooked up to my airport extreme to extend my wireless network. Those devices that connect to my Extreme download 25+mbps. Those devices hooked up to my airport express (those that are farther away and naturally pick the closer router, which is the express) won't break 1mbps. I live in a remote area, there is no inteference I can find (I downloaded iStumbler), I've changed the channels from auto through the range, I've done everything I could think of to try to figure this out. As far as I can tell there is just some sort of incompatability between these two devices that should go together like peanut butter and jelly. Instead I've got peanut butter and anchovies. I've googled around, I'm not alone, and I have yet to see even a decent attempt at a solution. IF you have one, I'll offer you kudos galore! Thanks!

Start your investigation by taking the AirPorts to an Apple store to have them checked out for proper operation.
Assuming that they work correctly at the store....and you continue to have difficulites at home.....it's pretty clear that something in or around your home is causing the problem.
iStumber will not display the signals from an offending cordless phone at your house or a close neighbors. Nor will it display any "closed" networks (you can't see the name of the wireless network) in the vicinity. Nor will it display a wireless security/camera system, microwave tower signals, satellite receivers, TVs, and the long list goes on and on.
I've had wireless difficulties in the past and could not figure out where the problems were coming from. I hired an RF signal pro, who came out with equipment and performed a survey of signals in the area.
iStumbler revealed a total of 4 or 5 networks. The professional equipment revealed 31 sources of potential interference problems, just to give you an idea of how difficult it can sometimes be to identify the real source of interference issues.
Post back when you have had the Apple folks check the devices out and we'll then try to narrow some of the possibilities down.

your router usually directs name resolution requests to bt dns servers
these convert web addresses that you type into numbers that the internet needs
bt dns servers are usually poor which could be responsible for the problems you have but the router doesnt allow you to change them
however it is possible to override them in the network settings of the pc

Internet download speed slows to 20% of normal every night at about 8:30 P.M. Pacific Time

My internet download speed, which averages just over 5 Mb/s most of the day, slows to about 1 Mb/s every night at about 8:30-9:00 P.M. Pacific Time and lasts for a few hours. It is consistent and constant so random equipment or line problems are unlikely. I've saved the results of my speed tests (speedtest.net) as to evidence the problem and posted them below.

Looks and sounds like the usual case of congestion during prime time hours. Have you tried asking Verizon to change the circuit or edge router your DSL line connects to, in order to solve the problem? Often times there seems to be an imbalance in how circuits are loaded on Verizon's DSL network. It's a rather typical experience for a shared medium (such as DSL, Cable) but steps can be taken to try and balance off load periodically. Verizon should have some free circuits available that will allow you to reach your speeds during the night time hours.

Download speed slow on Mac Pro but fast on MacBook Pro

I have an early 2008 8-core Mac pro, 6 GB RAM, running 10.6.8. I'm connected via ethernet to the HITRON CGN3 modem/WiFi router from Rogers. I'm only getting about 20Mbps download, and 10 Mbps upload. However, when I connect my 13" 2011 MacBook Pro (8 GB RAM) to the modem, also running 10.6.8 and using ethernet into the same port, I get about 80Mbps download and 10 Mbps upload. Even using WiFi, my MacBook Pro is able to get about 80Mbps download.
My network settings are the same in both my Mac Pro and my MacBook Pro. I should be getting around 60-80Mbps download on my internet plan, but my Mac Pro is underperforming.
Anyone know the solution, or have experienced a similar issue?
Thanks in advance.

Grant, you sir are a mega genius.
The culprit was the ethernet cable. I plugged the cable I was using for the Mac Pro into my MacBook and experienced a drop in download speed. Upon inspection, the cable had 6 wires. Who knew? This cable worked with my previous modem, and my speeds were pretty good. I just upgraded my internet package, and got this new modem, so I guess the cable is no longer incompatible.
Now that I've replaced the ethernet cable to my Mac Pro, my download speeds are smokin'.
Thanks, man, you saved the day!

Downloads Speeds Slow

I recently had my DSL modem/router fail. My service is through Qwest, and got a new Qwest sanctioned modem/router (Actiontec PK5000). I am using a wired ethernet connection to the modem/router. When I do speed tests it says I have a download speed of 1,200KB/Sec, but when I download a file it shows the download rate at <150KB/Sec. I contacted Qwest and they say it isn't anything on their end and that it is being limited by my internal ethernet adapter rate. I have no clue whether this is true or not, and if it is I don't know how to change it. Can anyone help me?

It's very rare to get the same speed during a speedtest and while downloading an actual file. It often has to do with the speed of the server you are downloading from. With a 1.2mb/s connection, 150kb/s isn't a bad download speed.

RV082 used dual wan download speed slow

Hi
I have a RV082 and I used dual wan , every ISP downstream is 10MB/s. two ISP downstream total 20Mb/s.Rv082 use loadblance mode,but total Lan PC download speed was 30kb/s-90kb/s,is very slowly .I find similar question inthe forum ,but i can not .please help me
thanks

Ok, several things here:
- Make sure that when you connect every individual LAN you get the full downstream speed.
- Make sure that it is not a PC problem, check with different PC's to see if the speed is the same on all of them.
- Download latest version of Firmware, you can get it from the cisco website, here is the link: http://tools.cisco.com/support/downloads/go/PlatformList.x?sftType=Small+Business+Router+Firmware&mdfid=282414011&treeName=&mdfLevel=null&url=null&modelName=Cisco+RV082+8-port+10%2F100+VPN+Router+-+Dual+WAN&isPlatform=N&treeMdfId=&modifmdfid=null&imname=&hybrid=Y&imst=N
- If you have to apply the new firmware make sure that you reste the device to factory defaults aftre the upgrade.
- Disable SPI under the firewall settings.
Hope this helps.

Download speed slow

I've recently purchased a new macbook retina 2014 13". What I've noticed is that the download speed is extremely slow, I get 500 kb/s, this is really slow for me and I actually bought this laptop for downloading and watching movies ... I've done a speedtest and it tells me

I have done a speedtest and it tells me I should get 80 mb/s,
Can somebody help me?

38mbs download speed, slow browsing bur fast downl...

Hi,
I currently get 38meg download speed from BT however my general browsing is not very fast at all. In fact standard broadband I have about 6 months ago was faster!!
My actual downloads are very fast I am happy with that but its the browsing nternet that is really getting frustrating.
I phoned BT and they checked all the settings of the router and checked the line etc and reported no problems but my problems still persist.
MY laptop has 6gb ram and a dual processor, there has never been any problems before in fact its the same laptop when I had standard broadband which ran fine. I use Google chrome too for browsing and run regular virus scans with BT net prtector (or whatever its called)
Anybody have any idea why this may be, as at present I think I am going to cancel my contract in light of the price increase all beacause of this and go else where?

Download Speeds slow on Mac, not on PC, Parallels or Bootcamp?

I recently switch from DSL to Cable because they offered higher speeds. I don't know if this affected DSL before because they only offered up to 2.5Mbps, the cable internet I'm on now is a 7Mbps/1Mbps line.
For the life of me, I cannot figure what is happening with my configurations. I have 2 PCs at home, a intel imac, and a macbook. When I run speedtests on dslreports or when I download large files from microsoft/apple, I get great speeds on my PCs. Around 880KB/s down. However, when I try to do the exact same thing on OSX, I get speeds around 260KB/s and it seems to be capped there.
The strange thing is that when I run parallels or boot camp, and try the exact downloads or speedtests I get the correct 7Mbps that I'm supposed to get. Am I doing something wrong with my configurations on OSX? It doesn't make sense that I can download in a window on OSX running paralles and get the fast speeds but thru OSX I cannot?
Both OS's are running Firefox. I've tried Safari and Camino on OSX and get the same results. I'm guessing its not a hardware problem because winxp on parallels and bootcamp get great speeds. This affects both my iMac and macbook. Any help would be appreciated

I have a 24megabit ADSL+2 connection and I had the same trouble as you.
When using Ubuntu or windows xp in parallels I had maximum uploads and downloads. But this was not the case in OSX.
My ftp uploads in osx were like 45k yet in ubuntu the were 120k to the same server.
I tried all sorts of methods to fix the problem.
But it turned out my problem was the router, I had a thompson/alcatel router a recent model.
I tried a cheap netgear adsl2+ router and bingo all my problems went away. I now have the same speeds in OSX and XP and Ubuntu.

Download speeds slow

I am migrating my iTunes library from an XP box to a new Mini server. I have a cable connection running at 25 mpbs down and 15 mpbs up. When I initiate a download from iTunes store it frequently begins downloading in the 200k bps range and drops down to 50kbps. I have seen it drop as low as 7 bits per second. If I shut down and restart iTunes it sometimes comes up at 5 - 7 mbps and stays there. Other times it drops back down to less than 100kbps.
I have actually run speedtest.net and bandwidth speed test on the mini while it is downloading and seen 20 - 30 mbps. This is while the mini is downloading at 50kbps.
Any ideas or suggestions on how to address this issue?
I have been running iTunes since 2006 and did not have this problem until the update about 2 months ago.

2014 Macbook Pro Retina crashes when extending display to Apple TV 3rd Gen

2014 Macbook Pro Retina running Mavericks 10.9.5 crashes and restarts every time I Extend Desktop in Airplay to new Apple TV 3rd Gen running latest update.
What can I do to avoid this?
Thanks

Hello Freytag,
I would be concerned too if my MacBook Pro was getting recurring kernel panics when using an external display.
First, I recommend troubleshooting the connection with the external display. This article is for internal and external displays, so you can skip any steps referring to the internal display. I recommend reviewing the section titled "No video or no signal, image distortion, 'snow,' or flickering" in the article below. I recommend reviewing the full article, but the following steps specifically stands out to me for the situation you are experiencing:
Reset the system
You can reset the Mac's parameter RAM and SMC.
You can find the full article here:

If you continue expereince kernel panics, I recommend following the steps in the section titled "Troubleshooting a recurring kernel panic" in the article below to help isolate and troubleshoot this issue:

My downloads keep pausing when my display goes to sleep for a while! How do I stop this?

I use a MBP retina and my computer settings don't allow it go to sleep. Yet, everytime I download something I have to sit with it or else it stop when I go away for five minutes.

Out of curiousity, in your power settings do you have it so that just your hard disk is put to sleep if the computer is idle? I think I had a similar issue a while back on WIndows that was caused by that one setting. I don't use a mac so I am not sure if the same thing applies.
