OS X :: Fast On One Mac Slow On Another? Same WiFi Network
Apr 1, 2010
I have two Macs that I use in my apartment on the same WiFi network. The network is made with my Apple Airport Extreme router. The problem is, on the iMac (2009), internet works perfectly. I checked on speedtest, it is just as it should be! On the Macbook Pro (2006), it is horrible. It may take up to half an hour to load a 4 minute YouTube video, a minute to load a page, etc. The WiFi connection on both is 4/4. I have done a software update for both of them recently.

I'm facing a very misterious issue with my internet connection, using a Time Capsule; If I use a network cable to connect to the Time Capsule, the connection to the internet is very slow (Maxes at 2mbit, never more). If use a wifi connection to connect to the same Time Capsule, internet is flawlessly fast, reaching well over 80Mbit.
I checked and the ip is always the same, the downloads are the same, at the same time. Even trying with 2 computers (a Macbook and an iMac) (one over wifi, one on ethernet cable) the one using wifi can download stuff way faster. If I switch connections the one using wifi is always faster.
I use DHCP for both ethernet and wifi on the same local network, all the machines can see each other, it's just the internet connection that becomes so slow when using ethernet. The local network as as fast as a gigabit connection allows. The Time Capsule has the latest firmware installed, and has no problems at all besides this internet issue.

My Internet has just been upgraded from 2MB/s to 10MB/s. To confirm the upgrade I have used [URL:...] to test my upload/download speeds with Firefox and Safari. I have 2 computers on my network which consists of a cable modem connected to a white airport base station with 128 bit WEP encryption in 802.11 b/g compatible mode. The 2 computers are a dual 2.8 ghz MacPro which is wired directly into the Airport base station by Ethernet and an iMac 1.83 Intel core 2 duo. The much faster MacPro only achieves a download speed of 5.5MB/s over its wired connection while the slower iMac achieves 9.8MB/s - very close to the advertised speed over its wireless connection. These are consistent speeds not one offs so I am wondering why the difference? The MacPro is my main machine so I'd like to have the best speed possible on that. What can I try?

Sorry for the title but I couldn't think of anything better. Hopefully I'll be able to explain my problem. I have a MPR 2.53 ghz, 4 gig ram, I'm using Safari 4.04. I am using the WIFI at a guesthouse in Thailand (but I had the same issue in China, Vietnam ...). I ran a speed test and it said download 7mb/sec and upload about 1mb/sec. I have an "app" that says bandwidth in 1.3kb/sec out 1.0kbs. I thought maybe it was Safari so I downloaded and installed Firefox. firefox gives me similar speeds. When I downloaded Firefox though I had a download speed of over 1mb/sec. But as soon as it finished downloading the speed went back to around 1kb/sec. I have rebooted my MBP many times. I did some Google searches but didn't find anything helpful.

I've been having Wi-Fi issues with Yosemite (both 10.10 and 10.10.1), but only on my home network. All other wi-fi connections have been strong/reliable. I also ran the Yosemite beta from July (I think) until the full release, but did not have any similar issues with wi-fi.
Here are my hardware specs:
Plus a 500gb hard drive.
Here's the info on my computer's wi-fi card, and my wi-fi network itself. Router is a Linksys E1000 (which is ancient, I know, but I can't afford a 5.0GHz router right now and that seems like the only worthwhile upgrade).
Info:
MacBook Pro, OS X Yosemite (10.10.1)

I'm encountering an issue with a new Macbook Air and would grateful for any insights. I have an Airport Extreme (latest model, 5th gen, A1408) based network (all updates applied). I have a new 2012 MacBook Air (11") that I noticed was suffering from VERY slow wifi speeds. After looking into it, I realized that if I used the configuration utility to separately name the 5GHz network and connect to wifi on the 2.4 Ghz network, the speed radically improved.
To illustrate, using speedtest.net, I saw download speeds of 35-38 Mb/s using the 2.4 Ghz network. This drops to 2-3 Mb/s when using the 5 Ghz network. The Macbook Air is showing an RSSI value of -56 when connected via 5 GHz and -51 when connected via 2.4 Ghz.
Other deivces in the home have normal connection speeds on the 5 GHz network, as does a previous generation, 2011 MacBook Air.A friend's also new, 2012 11" MacBook Air exhibits the same symptoms, so the issue is not specific to my unit.
Info:
MacBook Air, Mac OS X (10.7.4)

MacBook. 2Ghz Intel Core Duo. OS Snow Leopard 10.6.6. I'm running a 2006 MacBook with Snow Leopard. A few months back it started dropping wifi connection. Airport would show no connection but would list my network along with others in my building. If I tried to connect with my WPA password it would just time out. At this time I was running Leopard.
Since then I've done a few things.Tried running the Netgear router with no encryption at all (same thing happens). Will lose connection and then time out trying to connect
I've tried the MacBook in a coffee shop with wifi access and at my parents (same NetGear router) and at my new apartment with a horrible Orange Livebox.
Taken the MacBook in to see the genius bar at Glasgow Apple store. Worked fine for them, but I explained it was intermittent but we could not force it to fail. I'm sure if it ran for an hour it would.
At present if I have the MacBook in the living room (where the Livebox router is situated) its fine and wont drop connection. If I walk some 5m to my bedroom it will work for approximately half and hour and then lose it. A few days ago I bought the Snow Leopard upgrade and installed it last night. MacBook runs a hell of a lot faster (yay!) but moving it away from the router and its dead as disco in half an hour.
So to clarify, the MacBook has been tested on 4 wifi networks/ locus with same issue. iPhone, Xbox 360 and PS3 all have no issues with dropping connection no matter where they are in the apartment.
Apartment is a new build and its walls are not made out of lead or kryptonite. Is this a hardware issue rather than software? When updating to Snow Leopard it was an update to the existing OS of Leopard not a clean install.
AIRPORT says the following in System Profiler.
Software Versions:
Menu Extra:6.2.1 (621.1)
configd plug-in:6.2.3 (623.2)
System Profiler:6.0 (600.9)
Network Preference:6.2.1 (621.1)
AirPort Utility:5.5.2 (552.11)

I have a 2008 2,4 MBP and I have a problem with it. I was using snow leopard and everything was going fine for a few months. Then suddenly, it froze on the desktop at the opening. After few minutes, and command+ctrl+Shift+esc, and a few prayers it sometimes came ok.
I got tired of that and decided to format my hard drive and reinstall osx. I had to do it 3 times before it worked. Then I installed the updates and BANG! New problem! Now it was booting for 6 minutes before I see the desktop.

I am running an Ethernet (hardwired) connection from my Comcast modem to a Netgear WNR834B v.2 router then to my iMac 20" 2.16Ghz (previous white version)'s Ethernet port. I did this because I have been experiencing slow connection and frequent drop-outs (gets disconnects frequetnly when playing WC3). Now that the same problem still exists when using this wired setup. Whenever I open up Safari and go to a webpage , the page hangs while loading, and it will take about 10~20 seconds to get the page fully loaded with pictures and everything else. If I unplug the Ethernet cable that goes to the iMac from the router, and then plug it into the modem (so that my iMac is connected to the modem directly), the connection speed is blazing fast, and the webpages would fully load in no time. Therefore I am wondering what might be the cause of the slow Ethernet connection? Is it my router since that connection speed is super fast when connecting to the modem directly?

I got a white iMac G5 about a year ago. Everything has been working fine until recently when I started to notice that its REALLY SLOW. What I mean by this is that whenever I try to open an application, load my widgets or basically do anything, it is really slow and Im seeing A LOT of beach balls. Just as i started typing in the title for this tread, it gave me a beachball. This computer is not that old so it should still be running smoothly.
Does anyone know why this is happening?
btw: I have 1GB of RAM, but it still operate really slow when I only have a few application open.

I think there's something wrong with my Mac. The surfing speed for web pages can be extremely slow, even when I checked bittorrent download speeds to be above 25kbps. Even for webpages like major sites like amazon.com and flickr. Any ideas if there's any setting I need to tweak. I've tried different browsers and it's still the same.
Here are some extra info:
- Max possible download speed 800kbps
- Torrenting and downloading at same time. I download small items so torrent speed is typically around 25kbps
- One other user in network. I'm using WiFi on a Buffalo router, and cable modem.
Problem starts after surfing for a while. Maybe 10-20 minutes after logging into the network.

Recently my macbook slowed down during it's initial boot process. It now takes 42 seconds just for the apple logo to appear. Finally after 1:20 I'm at the desktop. I can certainly live with this but am just curious as to why all of a sudden the initial process has basically doubled (getting to the apple logo).

When I open up my finder, and try to search through files with my mouse, i will click on a folder with my mouse and the sub folders will not show up. It looks like they don't exist. BUT when I use my up and down arrows to search through the files, everything works great. The files show up immediately.

The wireless on my mbp is really slow most of the times -- about 3Mbps. I get 13 Mbps via ethernet. (speedtest.net) A windows machine connected to the same network gets 13 Mbps on wireless as well as ethernet. Even my iphone gets 12 Mbps. I guess this rules out problems with the router (DLink DI-524 with WEP). Tried OpenDNS servers, no change. Also tried disabling file/internet sharing, Ipv6.

Been months and issue is still the same, why does my desktop work blazing fast online from browsing to loading streaming videos etc. And my Macbook Pro can't, its a little slower browsing online which I can put up with but youtube, rottentomatoes, basically any streaming type site sucks. And it doesn't matter whether it's by wireless or connected directly by ethernet. It just buffers like every 15 seconds (does the samething on Safari and Chrome). I mean before my 4 year old HP laptop died it could load videos on those same sites almost instantly with no buffering.
I have a friend with an Imac that does the same thing, and a buddy brought over his MBP 15 and same thing happened like at his house, and I showed him how fast the desktop is in comparison.
I just moved to a new condo, have high speed internet from Comcast, and its def not the internet since the desktop works perfect. Any ideas on what to do as I use this MBP more being I carry it around the place and its so irritating knowing how quicker my desktop is, and that desktop is 2 years old.
I've tried different DNS etc and that helped a little bit (was a lot worse before) but still sucks, this is what I have inputted from this forum under DNS servers:
208.67.222.222
208.67.220.220
4.2.2.1
4.2.2.2
8.8.8.8

After running an internet speed test I find that my download speed is only running at 1MBps, despite paying for 5 MBps. The upload speed was as advertised at 500 KBps. So after firing off a nasty e-mail to my ISP (DOH!) I try to troubleshoot the problem. Lo and behold, if I plug the notebook in directly to the cable modem it runs at 5MBps! Is there some internal setting either in the computer or router that is slowing me down? FYI I am purchasing the .n technology soon with time capsule and a new iMac...but this old notebook won't handle it.
the details:
PowerBook G4
1.5 GHz
1.5 MB Ram
Airport Extreme Basestation 802.11.g speed
Cable Modem running at 5MBps

I'm not sure if many others have found this problem but my internet has been suffering recently.
I took a speed test on speedtest.net which stated that my download speed was 9.7mbps which is what I'm paying for, but still my browsing speed is ridiculously slow on all websites.
I've tried using firefox and chrome but they all seem to be having the same problem.
I am connected by ethernet as airport has full connection but can't seem to load anything. I have also tried to configure my ethernet connection manually as i read that this would help the issue.

I have a slow network issue. I'll try to make it as simple as possible.
1 MacBook Pro
1 Airport Extreme
1 Airport Express to Extend the Network
The network to my living room was slow, so I added the Express to extend the network. When connected through the Express, with a Time Machine backup, I'm getting about 500K/sec transfer speeds. When I move the laptop away from the Express and close to the Extreme, the network works much faster, about 5MB/sec. I don't understand why the network is so much slower when using the Airport Express as a network extender. Is the speed difference normally that much? If it's not supposed to be, is there anything I can do?

I recently purchased my first Mac computer, a MacBook Pro with Intel Core 2 Duo processor. I receive free internet included in my apartment rent, and I don't use a router, instead I simply plug into the wall. I previously used a Toshiba laptop with Windows Vista and there was no problems. I am not very knowledgeable about computers really, especially when it comes to the internet. I need advice on how to speed my downloads, but speak to me like you would 2 y/o.
I can't seem to find anything that applies to me or I can understand. I'm currently using Transmission for torrents and Safari for browsing, but my general internet connection outside of downloads seems to be fine.
