Internet slow in Mac OX but fast in Windows on Intel Mini??

I found this on the apple discussion board....

Chrispy,

See below for a possible fix I found on the apple discusison board. I'll be trying at home tonight. I don't know why it will help since it looks to change something under the Airport window and my mac is hardwired. At this point I'm willing to try anything short of a re-install.

By the way, my service isn't any slower with the Insight upgrade I just noticed the start of slow web surfing on my mac coincided with the upgrade, surfing on my wifes PC is just fine.

Good luck with the Insight "upgrade" hopefully they got their s&%t, I mean, act together.
.......

Hi All...

I posted a while ago about the slowness of my Safari and the fact that the slowness was not isolated to Safari but ran across the board. All Internet browsers and any other application that required the Internet was bogged down in the same way.

I came across this fix on the Macfixit forum and have been up and running at normal speeds for all applications, including Safari. I've input two DNS servers per the advice on Macfixit. Here's how I did it:

System Preferences > Network > Airport > TCP/IP > DNS Server box type 4.2.2.1 <return> 4.2.2.2 > Apply Now

This should bring you up to speed. It did for me! And I didn't have to do any archive and install, change folder settings for icons, delete plists or reset Safari (per the incessant advice here that these methods should work - having tried it all myself before with no results). Thanks Macfixit!

Work for you, too??

Take care!

That is Verizon's DNS server you may want to find out what your ISP dns servers are and enter those it should be on there website.

Hm.. it works well on Verizon's DNS. If anyone knows what InsightBBs is let me know. I'm searching the site with no sucess :(

Ok it looks like InsightBB is know for slow and unreliable DNS servers. They also do not like giving out the ips. So you may as well stay with verizons IPs. However for other people out there you should try not to use verizons its a courtesy thing.

I know you probably don't want to explain this but what exaclty does the DNS server do? I am very network stupid and I always wondered. Also, the connection is fine on windows so does windows automatically pick Verizon's DNS server... this probably sounds really dumb to those that actually understand this haha. You don't have to explain if you don't want but I was just curious.
 
Here's an explaination of DNS.

Also, you should compare your Windows DNS address with the one on OS X. If they are different, change your DNS in OS X to match Windows. I'm just taking a wild guess here, so correct me if I wrong...

How do you check it in windows?
 
Okay i havent had chance to read all the posts so sorry if i duplicate any advice.

Try first disabling ipv6 under your network options for the connection you use for internet access. This has speeded up my connection no end.

If your connection is still slow you could try a few things, apple has a broadband speed applet to speed up access for people with fast connections - see apple.com

otherwise, have you got more than one pc on the network we could do some transfer speed tests between the two

Edit: regarding DNS,

Google this as os x has some known dns issues when using a routers!
i manually added my dns servers as external to get past this
 
It doesn't matter whose DNS servers you use, just so long as you specify some.

I've been using those 4.2.2.1, 4.2.2.2... (they actually go all the way to 4.2.2.6) for years now since I had Verizon Dial-Up service, and I've had Comcast cable for 6 years.

Also, type in "verizon.net" in the search domains box.
 
Slow unreliable DNS that works better with Windows than Mac, lemme guess they're running DNS on NT4? If you want to further improve performance and have lots of sites you visit frequently run a caching DNS server on your Mac and make the first DNS server localhost (127.0.0.1).

May I ask why? That just adds "verizon.net" to any hostname that is not fully qualified. i.e. http:/www would get resolved to http://www.verizon.net.

Is that really what you want?

Thanks for the tip. So by putting 127.0.0.1 as the first DNS the computer will check my cache first and then move on to the verison DNS servers? That seems like it would help things along nicely.

I've always done that its what verizon told me to do.

4.2.2.1
4.2.2.2
4.2.2.3
4.2.2.4
4.2.2.5
4.2.2.6

and then "verizon.net"

I'm going to contact the cable company tomorrow about this. My roommate is very upset becuase her PowerBook G4 is so slow on the internet.... and never was in the past haha. Sigh..

i find it funny that you have cable internet. when i cancelled verizon to get cable the cable guy came out to set up the modem. it was seriously slow, i told him forget it my verizon dsl is way faster. i asked him if he set it up right and he said yes and that it must be my computer.

well, i told him i wanted to cancel and he said to call the office which i intended to do within the following couple of days. however something happened. i dont know what but the connection started to run as expected. it now runs fast, i loaded the yahoo page and started counted as you did but instead of counting to 10, i got to "1".

i really dont think its your computer. i mean it might be the mini in the sense that its holding on to some network information thats holding it up but im sure its fast if set up properly.

how long have you had your cable internet? try reseting the router, modem and computer settings. maybe trash the plist for safari? if its a new internet service provider i bet its a negotiation issue between the hardware. i was lucky, my modem and router seemed to work the problem out on its own after a couple of days.

Ah, but VZ is your ISP, not the OPs. So if they were to use VZ's DNS servers, they wouldn't necessarilywant things to default to verizon.net.

I'm not sure what you mean by things defaulting to verizon.net...
 
I use Verizon's DNS servers too. They load pages MUCH MUCH faster than a lot of other ones I've been assigned by Road Runner and other ISP's.

I actually put the DNS servers into my router though, so I don't need to configure them on each computer...maybe try that Chrispy.
 
I have the same problem!

I have the same problem and it has spread across all MACs in my house. I have two IMACs and three Macbooks. All of them are experiencing the same problem - the browser lags a ton when it is loading a new paghe, then it all comes in nice and fast after the initial delay.
