So it sounds like your DHCP server (presumably in your router) is not working properly to supply the DNS server addresses to your Mac.

You can check what DNS servers are currently being used by your Mac via the following command (in a Terminal window):

cat /etc/resolv.conf

Check to see if there is a firmware update for your router.

I have made some discoveries. I went through the Network Assistant from System Preferences and reconnects the laptop to the wireless. The internet performs as good as it should be this time even without DNS IP.

And i also ran the the command 'cat /etc/resolv.conf ' on the terminal and it did return the 2 DNS IP specified on my router.

Thanks.

Macbook slow wireless - a fix that worked for me
 

Looks like a number of individuals, including myself, are having the same problem with their Macbook. Internet on my wireless network used to be fine for months and degraded in speed sometime during the past month or two, whereas my other laptop (a Dell) saw none of this problem. I have nothing to back this theory, but I would not be surprised that a recent firmware update or software update triggered the behavior.

In any event, after trying a number of things (network assistant, reset modem,...), the simple fix for me was to manually specify the IPs of my DNS servers. Why is it now necessary for me to specify those beats me. In any event, for those that are unsure where to get the DNS server settings, they are provided by your Internet Service Provider (ISP) and should be on the paperwork you received when you signed up with your ISP. If you don't have any trace of it, call your ISP and ask for a complete network configuration document. Once you have the DNS server names or IPs, follow these steps:

Apple menu >> System Preferences...
Click on Network
Double click on "Airport"
Go to the TCP/IP section
Enter the name(s)/IP(s) of your DNS server(s) (If you have multiple IPs/Names to enter, remember to enter each one on a separate line)
Click the Apply Now button
Go on the internet and see if the speed improved. For me it was obvious and immediate.

I hope this will help some of you!

Many thanks to Fang and FrenchT for the tip on manually setting the DNS addresses in System Preferences.

I just bought this MacBook and was ready to put it up for sale on ebay (since the return period was over). But, since I love everything about the MacBook, I can keep it now that the internet isn't rediculously slow... Thanks again.

I just realized I have same problem.
 

I never really looked at it that much but by looking at this link it made me realise that I too have the same problem. I guess I never noticed it because I've never had wireless internet b4 because my parents just got it a few months back. I have 16mb SKY broadband which I know should be very fast. I also tried that link u put http://www.crailtap.com/c3/feature_f...mp_whatevs.mov and it also 4 me took about 30 secs. What is the problem? The router came with the package so I don't know if I'm allowed to buy a different 1 if that is the problem and it also had NETGEAR so anyway I have same problem and I'm just realizing it so if any1 can help plz do.

P.S. If I seem dumb its becuz I'm very tired as I going to bed now, and also when ever I download things like game demos that are like 600mb it will do it blazing fast wirelessly as I never use cables in about 45mins to an 1hour and a bit, so I know the download is very fast but just loading pages with videos and pictures are slow just like that link above. THX!!! and plz help.

I too am having issues with slow wireless on my new macbook. I am on a college network, and while I have no issues while plugged into the network, it's the wireless that gives me trouble. I entered the WEP code for it, and it then connected to the wireless, but it runs ridiculously slow in comparison to other people's. My school is very much pro-windows, and I think I'm like one of three kids with a mac, so it's quite likely it has something to do with the school and not macbook. But I ran that test that was suggested and this was my result
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 31805 100 31805 0 0 3011 0 0:00:10 0:00:10 --:--:-- 143k
name lookup: 10.124 connect: 10.234 pretransfer: 10.245 starttransfer: 10.347 total: 10.560

I have absolutely no idea what that means, but I was hoping someone might?

I suppose I should also mention that my wireless worked fine at home.

Ok just got off the phone with Sky(even though they don't know anything) and they said that I should be gettin 15mb as from what they can see it is getting that. I checked my speed with this website http://www.broadbandchoices.co.uk/sp...partner=bc~jmt and I get about 9.30mb Max. Then they told me to go into utilities and go to network utilities and I checked the netstat to "display the state of all sockets" and SKY said I should have less then 10 networks or so but I did it and it all these things of writing and stuff and its waaaaayyyyy more than 10 so SKY said that is the probs I have too many which are taking my speed so question is how the flip to I get all those OFF. Sky said to get their Mcafee which I did and it will scan and bla bla and I did and they're still there. This is making me sooooo mad because 16mb is sooo fast and I'm only gettin 9mb max and I game multiplayers and need the speed 4 hosting servers and bla. PLZ help me somebody. Going MAD.:eek: :confused:

Ok just had a friend over with his PC laptop and he got up to 15mb, where as my macbook would only get like 9.64mb max. This is so annoying. I have a DG834GT NETGEAR router provided by my ISP SKY Broadband. Have tried with cable and still slow.(in fact most of the time slower then my wireless) Rebooting router, going into router settings, changing channels etc. etc. I'm seriously going mad as when I play games like Halo and I check my ping its so high compared to every1 else and avrage person has 8mb. This has been going on 4 so long. I might go to Apple and take it to a super Genius and see what happens, as I know it is not my ISP's fault becuz my friends PC laptop was reaching the speed, and I have called SKY so many times, which by the way is the worse thing I could have done as they just put me on hold on transfer me to all these tech people who then make no difference, and just run up my phone bills. Plz I need help. Anything would be appreciated.:) :confused: :mad: :mad: :mad:

This also worked for me. I have a dlink router and I had tried turning the turbo off and the other stuff.

DNS settings fixed this - it was same address as my router

D-Link 614+ Solution
 

I've got some progress with a D-Link 614+ router and my MacBook. I was dropping about half of my packets and getting crappy performance. Here's what I did to solve my problem (currently running perfect with almost no packet loss whatsoever, and websites are finally loading fast!):

First of all check D-Link.com and make sure you have the latest firmware (3.44 I believe)

Login to your router admin page.

Click Advanced then click Performance.

Change all your settings as so:

Airport slowdown due to Apple security update?
 

I noted that my wireless performance (MacBook Pro, Tiger 10.4.9, Linksys router) degraded soon after I used Software update to install Apple's latest security patch. I have tried rebooting computer, Linksys and DSL modem - all to no avail.

Now its seems as though there is a "pause" prior to loading of pages. I have otherwise changed nothing in the system and there are no new netwworks nearby.

Perhaps there is an additional security-related "filter" in place now? Just guessing. This slowdown corresponds in time to that noted by several others.

macbook slow wireless
 

My wife's shiny new MacBook had tearfully slow Internet connections using our D-Link DI-614+ wireless access point. My old G4 worked fine through wireless, and the MacBook worked fine if you plugged it in with an ethernet cable. :confused:

The best way to measure this problem is to ping the router:
From the command line, enter "ping 192.168.0.1" (or whatever the IP of the router/WAP is). Let it ping a couple dozen times, then hit Ctl-C to stop pinging. It will give some summary statistics about your pings.

The MacBook would lose about 20 to 40% of packets. The old G4 would lose none.

I spent a half hour with Apple"Care", who finally sent me off to spend two more hours reinstalling the operating system (!?!? their idea, not mine). This, of course, did no good. :mad:

Just before throwing in the towel, I tried One More Thing...

In the web-based configuration for the D-Link, click the tabs to "Advanced -> Performance" and set the following:
TX rates: 1-2-5.5-11 (default is 1-2-5.5-11-22 Mbps)
4X Mode: disabled

Then click the "Apply" checkbox so it will restart.

Works fine now. :D

Apparently, the WAP was trying to talk too fast, and the MacBook ends up losing packets (22 Mbps is NOT a standard speed for 802.11b, which only goes up to 11 Mbps). I guess the G4 never tried to talk that fast in the first place, so it had not been a problem for lo these many years.


Now I see this is the solution posted by neikous - I'll put this up again in case anyone else can't get the screenshot image (it didn't come through for me the first time I looked).

Slow Internet connection on Black Macbook
 

One day I had a slow Internet connection on the Macbook. Didn't have problem with PC. So I plugged Macbook directly to the DLINK D665 router and it was still slow. I use Sympatico High Speed and was very puzzled since I didn't have this problem before.

How I fixed the problem:

1. Remove any DNS servers from network settings (didn't have this on Macbook since I use DHCP).

2. Remove DNS entries on the router (This is what I had all the time in the router with no problems before).

3. Reboot router and restart Macbook.

Wirelesss and Wired connections now fly. Note: I have installed the N-HiFI enabler and updated all Airport Epxress.

This...
 

****THIS WORKED FOR ME****

I have been having this issue since I bought the computer. I just never really sat down to figure it out. First thing I did was get rid of the little icon on the toolbar that showed the internet connection and that really sped things up but the pictures were still not loading as fast as I liked. So I played around more and then went into network settings and put in my DNS server info and IT FIXED IT! Thank god, because I just posted it up on Myspace for sale! Well, I guess I don't have to sell it anymore!

If anyone has any questions please feel free to AIM, E-mail or whatever me! I know it was really frustrating for me to see everyone post that they had a problem and then not post that they fixed it and how. So, feel free to ask away!

Thanks

FESTER:cool:

Dlink 624
 

I had the same issue and was totally bummed.

Here is how i sorted my netowrk out.

Logged into the Dlink access point.
Clicked on wirless and then advanced.
Disabled Wireless Qos(WMM).
Verified that superG was off.

Thanks everyone.

This thread is the best one on the topic I've come across during the last intense 24 hours of trying to find a solution to my problem. With a few days left of my return period I might have to return my Macbook and stick with PC. I was an excited convert until yesterday..

The wireless connection is really slow with my Macbook. I can't say it's bad when using the internet since internet is sometimes slow, but, it's obviously slow on the wireless LAN we have at home. I summarise the problem:

1. I have a BT Voyager 2110 wireless router. Conecting to it with a cable is no problem. Good fast speed. But using wireless means problems.

2. Sometimes my Macbook even have a hard time detecting the network. I feed it with all details (WEP, etc).. Eventually (could be many, many minutes after "fiddling") it detects it. Then I have full good signal. I am next to the router.

3. Transferring files (wireless) from another computer on the network is slow. Really slow sometimes. All traffic is slow (VNC, SSH, etc). If I use the cable it's fast. With the wireless I can be stuck at below 100 kb/s sometimes. With cable it's often 1100 kb/s. Something funny is going on with the wireless.

4. Most important of all: My Macbook is the only computer we have at home which has this problem. The others (PCs) work just great at around 1100 kb/s over the wireless LAN when transferring files.

I have fiddled with settings for the router, I have read this thread, but I can't solve the problem. I will have to go back to PC if I can't solve this in the next few days. I need wireless in my home. Any ideas of how to remedy this problem with BT Voyager 2110 router and Macbook?

This is the best thread I've found so far on my problem. I am so close to return my Macbook. I just converted and I am not happy! I will go back to PC if I can't remedy the wireless problem with my Macbook shortly (in a few days before the return period goes out).

I have narrowed down the problem to the router. The slow connection is obvious when I connect to other computers on our wireless LAN. Normally we transfer files at 1100 kb/s speed but with my Macbook it's sometimes less than 100 kb/s. I can summarise the problem as follows:

1. I use a BT Voyager 2110 wireless router. Connecting to it with a cable means good fast speed in all situations. Using wireless means problem.

2. I have noticed that the Macbook sometimes has a hard time detecting the router. It can take minutes of "fiddling" before it finally detects it. Then I have full good signal and I'm sitting next to the router.

3. File transfer, VNC, SSH connection, etc (on our LAN), is really slow when I use wireless. Sometimes it's as "good" as 400 kb/s but sometimes it's below 100 kb/s.

I cannot solve this problem? Do I have to go back to PC? Does anyone have any solution that work in my case? I cannot really apply the solutions posted earlier in this thread although the problem seem to be similar. My router is this BT Voyager 2110.

Anyone?

I solved the problem I described above. I changed the channel on the router to 11. Tech support told me that Macbook prefers 11, then 2 and then 6. I tried number 2 yesterday and it was still bad. However, channel 11 solved my problems. Now the wireless is fast as with cable.

Same Problems with Santa Rosa MBP
 

I've been reading this forum and have applied several fixes, but my new 2.2ghz MBP is still not running the net at speed. It is definitely the router (D-link 614+) because when hardwired through E-net it works fine. I tried DLing the latest firmware for the router but got a seemingly unuseable file: "NML.MEM". I'd like to install it but am not sure of how to do it. Any help?
