OS X :: Slow Internet Connection Speed / No Buffer Space Available
Jan 7, 2010
Because i'm a web developer i was trying some bandwidth limiting with IPFW in the terminal to test how my web apps will work with a slow internet connection. After i was done i did "# sudo IPFW flush" and thought i was done�
But then i got a feeling that my internet connection was slow so i tried "sudo IPFW pipe show" to see if i forgot to flush some pipes. It gave me an error message: ipfw: getsockopt(IP_DUMMYNET_GET): No buffer space available

I am using Windows right now. I never realized this but my download speed is supposed to be 768 Kbps. Though when I download something my speed is between 70 - 90 Kbps. Is this normal? I ran many virus scans and I am clean.Is there something that is slowing it down? I am also using wireless connection.

I am trying to download MediaWiki 1.18.2 and it is stuck downloading!
* I have all apps closed.
* The router/modem and computer are in range.
* The correct network is chosen (SkyCaptian)
* I can access the internet on my iPod without problems.
The internet speed is less than 1 mb/s, I am looking for a way to hack this speed?

Is there a way to tell which one is slow, if anything is going slow? I have an extremely old PC which is normally ok for most things, but gets bogged down if I am doing too many things.I was so annoyed with our national real estate site after they changed the format that I wrote a letter once a long time ago.. and I was ready to let them have it again, listing all the reasons why it is so bad and so much worse than the original.
Today for the first time, I accessed the site (mls.ca) using my new iMac. It was like lightening speed, comparatively speaking.Wow, suddenly I knew why the mls people hadn't changed their new format.But then I started going to other sites.. like airmiles.ca for example, and it was slow as heck... and stalling.. etc.
How would I be able to tell whether it is an internet slowness or the computer being slow?

I am having trouble with the ping speed on my internet connection; it is registering at 174 ms, which is too high. My iMac is a 2009 24inch model running Lion. Is this due to my wifi or is it the ip server?

i'm sharing my internet connection to other devices in my house, but I want to limit speed, because my connection speed is only 2 Mbps. Is there a way to limit speed? I'd like to leave 1 Mbps for me and 1 Mbps for other devices.

I live in a two-story apartment and my main connection is upstairs where the cable arrives and I have a time capsule to provide wireless connection. I can have connection even downstairs but in some places the level is very low so I have added a Airport Express. Now I have full coverage but the speed downstairs is very slow (perhaps less than half of the speed I have upstairs). Is there any way to tune the level of my connection? Any tool to verify there is the bottleneck?

I have a PowerMac G5 running tiger and am having painfully slow internet connection speed. There are 2 comps hooked to the router from the modem(my MAC and a PC), then another Router between the MAC and an XBOX 360. The other comp has consistently fast internet speed. I pinged [URL] and got the average above, no packet loss. I have:
-reset modem and both routers
-contacted my ISP all ok there
-bypassed the both routers and still slow(this leading me to think its a software-settings problem on my end)
-reinstalled OS
still slow. besides preforming a seance I am clueless, which isnt saying much.

My ISP is Mediacom (I do NOT recommend them), and I use a cable modem (RCA) straight into my iMac, 24" 2.4GHz, late 2007 Al, running 10.5.6 and Safari 3.2.1.
According to my iStat pro widget, my network in fluctuates between 1kb/s and 5.2Mb/s. Mostly the slow speed. Mediacom is sending someone out on Monday.Is there anything I can check or do in the meantime. The iMac is the only computer around here, and I've rebooted the cable modem until I'm sick of it. Even rebooted the iMac.I used to think TW was bad until I had to use Mediacom.

how I can speed up my internet. [URL]is says that I have a 10.71 mbps download and 1.34 mbps upload but for some reason my internet is always slow to load web pages etc. There a quite a few internet connected devices in my house (up to ten (iphones computers, xbox), but not all being used at once of course, with 2 Airport Extreme base stations.) Is this an interference problem or what?

After installing Windows Vista and running both OSX Leopard and Vista I started noticing a slow down from my Firefox and Safari both. Up until now I have had really good speed and great browsing and torrent downloads using Transmission,,I switched over to Vista and it was fast so I thought "what the heck is going on here", checked out the forums for some advice on different DNS etc, tried all of those with no results so finally called my ISP and they ran a traceroute with me from utilities and the first ping was coming back that I was behind a firewall. Checked the Mac's firewall and turned it off still no luck, made sure Little Snitch was off, still nothing. Thought how is this possible.
ISP(Time Warner Cable-Roadrunner) advised me to take the cable modem back and switch it out for a new one because they said my speeds were definitely not right. Well I decided to check my Vista and sure enough the windows firewall was on,restarted my iMac and used trace route again from network utilities and the firewall was gone. So some how even though I was running Leopard only at that time still with bootcamp somehow the firewall in Windows was bleeding over into OS X. I'm not a computer engineer but I thought they (Vista/OSX Leopard) were running independently from each other in bootcamp. Just wanted to let you guys out there know about this because it seems that some of the quirky issues that you can't find answers to might be attributed to this.

What's agood way to test the ethernet port on my G5 Power Mac SP 1.8G? I have other Macs on the network.
My wife complains that the internet is slow & can't stream video.Th is computer is wired to a gigbit switch, then to 100 Mbit switch then to the router. I have a 24" iMac connected to same gigibit switch and have no problem with the internet speed.When I try to send a large file between my iMac & the G5, the transfer is slow. I checked in System Profiler and both computers detect the ethernet speed as 1000 Mbit (1gigabit or something like that).
Ideas on how to resolve? Gigbit ethernet cards that will work in the G5?I don't have Airport on the G5.

Have a white macbook about 3 years old/intel etc etc..I have found that when I'm at home plugged into a hardwire internet connection I get respectable torrent download speeds (100-200kb's/sec). I work in the oil and gas industry in Alberta and stay at camps often..When I connect the same laptop there my torrent download speed is terrible (10-15kb's/sec) even though downloads are permitted and many of the pc laptop users don't have a problem with the speeds. Primarily use vuze but have tried a few other torrent downloaders..Is there something within my computer settings or downloader settings that slowing me down and if so could you provide any advice on how to over come this.

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?

My internet connection has always been very fast and I have never had any problems with its speed or loading of web pages. Over the last two day I have experienced extremely slow connection speeds and webpages have been taking forever to load. Is there a setting I can check or cache to empty to help speed up my connection? Or is there a disk cleanup to help get rid of whatever may be causing this problem?

I thought I fixed it with a wireless-n router and it worked perfectly till now. I was loading videos on youtube in seconds with no buffering and fully loaded, and could stream even 1080hd videos on there and other sites no problem. Now the MBP is going slow again, like there's this lag when browsing, and I can't even watch youtube videos anymore unless their 240p as anything else buffers every couple of seconds.
It's not the internet, as like I've said before I have an pc in another room across the condo on the wireless network and its blazing fast browsing and watching/streaming videos. I've seen other post about this lately and really leading me to believe these $ MBP just suck on wireless networks, b/c I can be right next to my router and no changes... and my girlfriends cheap netbook can stream videos faster with no buffering then my expensive piece of aluminum.
I saw someone else say enter this for DNS and I had already done that, so is something screwed up here?:
208.67.222.222
208.67.220.220
4.2.2.1
4.2.2.2
8.8.8.8
8.8.4.4
and Search Domains next to that says: domain hsd1.fl.comcast.net.

This is driving me crazy, so any help would be greatly appreciated.I am using an IBOOK G4, running OS 10.3.9. Never had any major problems with the computer itself I am currently living in Korea, and thus have very highspeed internet. However, on my Mac, it is running quite slow. There is no modem that I can reset, because the apartment building is already wired so my ethernet cable connects directly into the wall. A friend came over to test the connection (speedtest.net) with his PC and he was downloading 60,000 KBPS, when I plugged in my MAC I was downloading at 15,000 KBPS. He downloads various things at around 2mb/s and I sometimes only get 50 kb/s.

I'm using a new AirPort Express updated with the latest firmware and AirPort Utility and both my roommate and I have been banging our heads against the wall. Speed to the APE is 130 Mbit/sec and both of our computers are connected to the APE just fine.
This is what the ping looks like. Ping has started ...

When I did a speakeasy test, it turned out that I am getting exactly half of our allotted bandwidth. Is there a way to configure this APE to act more like a router that truly shares a connection rather than a splitter that's cutting it in half? Any help would be much appreciated as I'm getting download speeds of 7kb/s and it takes around 15 seconds to load google!!

i've got a 6 year old 12 inch powerbook G4 1.33 ghz that has internet speeds around 5177kbps, but overall its a bit dated sooo I wanted something a bit more new. I recently picked up a white 2.4 ghz Intel Core 2 Duo Macbook, HOWEVER the internet wireless speeds on it is dismal in comparison. I'm getting download speeds on average around 405kbps and upload speeds are pretty much non-existant! I've matched both of them to the same internet settings and they are both running 10.5.8. So again I'm stumped and if anybody can give me some idea as to what to do, Id greatly appreciate it!
