OS X :: Fixing Slow Internet Connectivity With Wireless-N Routers?
Nov 1, 2008
I must admit that this posting is a last resort. However, remarkably, on narrowing the problem it seems it has to do with an unknown default setting on my Mac OS X Leopard on both my MacBook and iMac.
This week I invested in two new Wireless-N routers - Belkin and D-Link - and both fail to perform. The problem manifests itself as follows:
- When my Apple is wirelessly connected to the router, it takes a very long time to pull up any website. And unless I am imagining things, it seems to first pause when the blue progress indicator reaches just beyond "[URL]" each time. It is slow loading beyond this initial pause as well.
- When I change my security from WPA2 to WEP to None, it makes no difference whatsoever.
- When my Apple is connected to the router via ethernet, it performs very well. Each website appears very quickly and as expected i.e. no wireless connection.
- Very surprisingly, when I am using Windows via Boot Camp on my iMac, it performs very well when *wirelessly* connected. This threw me a little. This is what led me to suspect there's a default configuration with my Mac OS X that is causing the problem.
- In light of the above point, I have not yet checked to see whether wireless frequency or channel affect the download speed.
- For 2.5 years I had been using a Netgear Wireless-G router without any problem.
Might anyone know what the problem is? Or at the very least how better to diagnose it?

For some time now, I have noticed that my Mac's internet is running super slow. I am saying slower than what I see on my PeeCee (Used for gaming such as CSS and Half-Life)! So, I set out on a Google journey to find that a lot of people have been having the same problem with they Airport. It seems that in some Apple updates, the Airports are having issues. So, I tried to fix it and I came up with this wonderful guide. My internet now loads Facebook in 3 sec instead of the 30 sec it was before and I can watch my good old YouTube videos in a flash.
First, Open your "System Preferences";
Next, go to your "Network" settings;
From there, make sure Airport is highlighted and click "Configure";
Click the "TCP/IP" tab;
Type 4.2.2.1 into the blank DNS Servers box, hit return and type 4.2.2.2 then click the "Apply Now" button like so;
Your internet may restart, but it will come back on right after you hit Apply! And your internet should now return to speeds like it used to have. I am running 10.4.10 and I am proud to say my Internet is fast as hell.

I'm having an issue with my MacBook Air on my friends wireless router in an apartment that I just moved in to. It is a Belkin N Wireless Router. The internet runs painfully slow. Takes about 1 minute to load a page, and sometimes it does not load at all. The internet and router work fine on my iPhone and another macbook. It just runs slow on my MacBook air. Anything in system preferences or anything I need to change?

There may be an easy explanation for this, but for someone who is new to Mac's entirely, it's proving to be difficult. I recently acquired a powerbook g4 15" powerpc 1.5ghz with 1gb ram and 80gb hd. I'm a computer technician at work, go figure, but only for pc's. The wireless works flawlessly on the mac at work, t1 connection. When I arrive home, my wireless is so slow and sometimes doesn't even work.
I have comcast cable internet, which is really fast on my desktop and two pc laptops. So with my comcast, I have their issued cable modem and a linksys wireless router. Any thoughts as to why this is so slow? Takes me like, 5 minutes to load facebook. I have Mac OSX 10.5 +, not sure what exact version. I think 10.5.6? I'm not connected to anyone elses internet and my DNS are the same on my PC.

So I have a wireless router from cox cable (motorola surfboard SBV5220). I also have my airport extreme base station connected to the wired ethernet in the other half of my house. So I have the cox motorola router hard wired to the ethernet in-wall outlets. And When I plug my computer directly into the ethernet plug in the walls it works great and fast. So I have the airport extreme plugged into the ethernet port in the wall to use wireless on the other half of the house that the motorola router doesn't reach very well.
Everything worked great until the motorola router went out one day and we had to reset it. Once we reset it, the wireless internet from the airport extreme started acting up. Half the time it works fine and just as fast as it did before. The other half it doesn't load a full page. It's not even working at all really. I tried to see if the problem happens when using the internet from the motorola router, but it wasn't consistent. Sometimes the airport internet worked fine while the motorola was in use on another computer and sometimes it didn't. I haven't been able to figure out a consistent cause.
I also had the airport express plugged in as a wireless extended for the airport extreme, but I took that out as it was pretty unnecessary. Also, I got a new mac mini and need to run it off the airport extreme wireless also. When I turn off the mac mini and use my macbook with airport extreme the problem still persists.
I tried google-ing and then searching on this forum and got many unrelated topics. I would really appreciate anybody pointing me in the right direction. I am a semi-newb when it comes to networking, etc...

My wireless used to work throughout my whole apartment. It's a small one bedroom...then one day it only worked while I was in the room with the router close to my router. This also happens at my parent's house, my boyfriend's house, at coffee shops etc....everyone elses computer gets access just fine but mine cannot even see the access point. Any one have any idea what happened or how to fix it?

I need a good wireless router , I have considering both the air port models, if anyone know of any that are better than the airport series and enables me to do the following. Stable fast wireless for gaming and large file transferes, and wireless transfere of data to ps3 as media center. Ability to add one or more USB harddrives and printer able to read and write data from the USB harddrives and printer, both from a mac and pc. Is there anything better than the airport extreme, and what problems do you encounter when using it.

I got this email from the manager of my dorm: Quote: This is a reminder that wireless routers of any kind are not permitted anywhere in the ***** *****. If you have one please disable it immediately because these are causing the internet for the entire building to stop working and it is very frustrating to residents who do not have internet access. This entire building does not have wireless capabilities. Every apartment is equipped with a modem for Ethernet internet access. We pay a lot of money to have Ethernet in every apartment so by using wireless routers when we don�t have wireless internet you�re not only stealing wireless from someone not affiliated with this building you�re wasting our money that pays the internet bill every month, and you�re causing the internet to go down to the entire building. ***** is working hard to identify where these wireless routers are in the building and disabling them as they find them. If you have one stop using it, or if you know someone that has one please tell them to stop using it. If you have questions about this please direct them to the IT department by calling Is there really a way for them to detect if I am using a wireless router in my dorm room? I am using an Airport Express and it is convenient because it allows me to plug my printer into the USB so my printer does not take up space on my desk. And I have a Playstation 3 in the common room with NetFlix. So do you think I should unplug it? Or are they bluffing?

I connect to a wireless router in work and at home, for home i just set the setting through firefox to connect "auto-detect proxy settings for this network" and it works fine, but in work, this does not work, i have to set it to "Manual proxy configuration" with an ip address the it department give me. What i would like to know are 2 things:
1) Am i doing the right thing my changing the settings in Firefox, or should these setting be configured outside of the browser?
2) How can i set this up, so i don't have to keep changing it form auto to manual each time.

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 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 just got a new MacBook Pro, but my wife uses my old 1.25GHz Alum. PowerBook. My MB pro flies, but unfortunately, the wireless ethernet on my old PB is slow as hell. I've got 11+GB of free space left on my hard drive and Safari or Firefox are the only applications I have open. I also have a cable internet connection with wireless through my 1st Gen Airport Express, yet it's still slow.

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?

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.

just got my 17" MBP today and it's beautiful. Playing a lot learning a lot (my first mac). Having one big headache though.What's up with the wireless speeds? I did some file copying from my Vista machine connected via ethernet and speeds were fine. Now I'm trying to copy some stuff from my girlfriends iMac over wireless (using a linksys wrt54g, both connected at G) and it's just balls slow. I'm talking about a meg a second, the hell?Now, what's really making me upset is the fact that it's also crippling my internet speeds when I'm doing this wireless to wireless file copy. It's like it's pegged so bad at the super fast 1mb/sec that I can't even browse the web without it timing out half the time. Internet is fine when the file copy is not happening.

Is there any point in mixing wired and wireless connectivity with a Mac Pro? Would this bump up/down speeds at all?

My wife has an iBook G3 500mhz with 320mb of ram. She is having trouble with the airport card that is installed in it. I have a 2.4ghz wireless access point in the upstairs of my house (next to my main machine) which is sending the signal to a 2.4ghz bridge in the downstairs. House is wood frame. She is having problems connecting to the wireless network. When she can actually connect, she has to be right next to a wireless router and even then it doesn't work sometimes to connect. Is the airport card going bad in this? Is it possible that the antenna has gone bad or has a kink in it or something?

I get great wireless connectivity under Mac OS X, since the wireless base is in the room right next to the MacBook Pro, but under Windows XP Home Edition with the Mac drivers installed, I never get above two bars, and connection drops every 20 minutes or so. Windows is completely updated, all boot camp drivers are updated, everything.

I have a PC laptop which also uses the wireless and has never had a problem.My Mac Pro loses access to the net every few minutes or so. I usually follow a sequence of "Turn AirPort Off" / "Turn Airport On" to cycle the connection, and this works but only for a temporary solution until it drops out a few minutes later.also link to pic here..[URL] It always shows full bars even though in the activity monitor it just flatlines or flutters near 0kB/sec. Like many others, my connection drops although the wireless signal icon remains full. I've noticed that as long as my system doesn't idle (ie - if I'm downloading something, or on a webpage which is always sending or recieving data) the wireless connection seems alright. But if I am on a webpage (for instance, this Apple website which is idle and not sending or recieving data) for a few minutes or am away from the computer for 5 minutes, the connectivity dies and I cant access the net. I then follow a sequence of "Turn AirPort Off" / "Turn Airport On" to cycle the connection, and this works but only for a temporary solution until it drops out a few minutes later. Also, can I ask that NO ONE suggest that I hook my computer up via the ethernet cable as there is no access points upstairs and I'm not going to pay a tonne of money to get one installed when I paid a tonne of money for my "AirPort Extreme" so I didnt have to (which was just over 2 years ago).
Its been a constant problem for the last 12 months and the short-fix of "Turn AirPort Off" / "Turn Airport On" to cycle the connection has driven me to madness (especially when I write a lot of information into a site for example this, and after 15 minutes I click the next button or send and dont realise the net is no longer connected and I LOOSE EVERYTHING I'VE JUST TYPED. It's happened 1000's of times.

I am starting a new thread. I was having connectivity to the internet issues earlier. I have an IPAD an IMAC and a PC. I had to unplug my router to move it. Now it seems that I can only get internet access on one device. Earlier in the day my PC internet worked and the IPAD and IMAC did not. After shutting down my PC the IMAC began to work. Is there a setting somewhere for multiple devices?

So every so often after I open my laptop up my wireless will work initially but then all the sudden will stop working. All I have to do is turn off airport and turn it back on and it works again.

My job requires me to be mobile, and I move from one office to the next frequently, to attend to various meetings etc. Every time I move from one office to the next, I have to turn WiFi OFF, and then back ON again, in order for it to re-establish connectivity. This is a major frustration, as quite often I am downloading or uploading work applications, and have to re-start the download / upload again from scratch. It's impractical to not move until these are complete.

Upon receiving the monitor, I immediately plugged it in to my Macbook, using the Mini-DV to VGA adaptor I already had, for use with projectors. The monitor was good, but a bit blurry and not too sharp, due to the analog signal. So I ordered a Mini-DVI to DVI adaptor. When it arrived, the improved picture quality was immediately apparent.
However, as time went on, I noticed my wireless connectivity was getting terrible. Extremely slow Safari page load times, and upon going to Terminal and pinging my router, I would often get response times of 21000 milliseconds, or worse! I did a lot of research, on router firmware, on wireless connectivity, etc., but to no prevail. Then, on a whim, while continually pinging my router, I removed the DVI adaptor from my monitor. The ping instantly dropped from tens of full seconds to just a stable 0.4 milliseconds! Using my VGA connection resulted in no worse wireless connectivity than without it, but upon plugging in DVI and stressing the connection a bit (i.e. downloading a large file), the connection went bonkers. The pings also immediately jump from 0.4 milliseconds to a range of 1-4 milliseconds, regardless of any "stressing".
