Hi.. I did what you described (I’m not a computer person.. and I find this all very confusing, but managed to get through until the dig program part.) my internet is still slow.. and I don’t know what to do. This is a recent occurrence and is really getting on my nerves.

I have a Mac OS X version 10.5.8

what should I do?

Great information. Some combination of using OpenDNS and disabling IPV6 did the job for me. I think my Netgear WGR614 router is partially to blame, I’ve read elsewhere that it doesn’t play nice with IPV6 requests.

Thanks for this! Setting up a new network location with the OpenDNS servers solved the problem perfectly. I especially appreciate your clear instructions, as I am a total luddite, but was able to follow.

Thanks again!

Ben,

I followed all your advice above, but the only thing that got better is my PING. It went from about 400ms to 230ms, which is still poor. This is really frustrating because I pay $80/month for 10mbps internet, but get on average about .5mbps. The other people I live with don’t have any problems. In fact, it seems like every time they use the internet for any reason, it takes practically all my bandwidth away. Also, my upload speed is consistently higher than my download speed.

We have called our ISP multiple times complaining. The tech support even had us write an email to the corporate office, but we have not received a reply, and probably won’t.

Is it possible my computer is slowing it down? Another guy that lives here has a brand new mac, but has no problems. The other guy has a PC, but also has no problems. It’s only when my computer is involved when it slows down. Could it just be my computer? I have a MacBook Pro I bought in 2007. If so, is there anything else you recommend?

If you decide to help me out, please put it in simpler terms as I do not know the entire internet nerd jargon (Ha ha).

Wow I really want to say that you’ve done a terrific job Ben, I reinstalled Mac os x to fix the problem but the slow-internet problem still persisted. Then I found your guide here and it was such a great help! Again, thanks Ben, wish you all the best.

I have solved the FTP problem. My router MTU setting was set to 1423 and my network connection on my Mac was set to 1500. I have changed the setting to manual and to 1423, and now it works. It was on auto, so it seems that auto does not work.

This have fixed issues on my mac. Paypal and Amazon for example did not completely load. It was as if the css files did not load. These files were on a different domain name when I had a look at the html source, and my mac did not want to resolve do those domain names.

However I still have another interesting issue: whenever I try to connect via FTP with FileZilla, the directory listing times out. In other words it does connect but the directory listing creates problems. All the above did not fix this issue yet.

I have had the wireless issue on my iMac (2008 edition) for months and after eliminating most of the other possible causes, I concluded that in my case the problem is most likely related to DNS/SRV lookup issues. My iMac running OSX 10.5.6 would not stay connected. The same machine on the same wireless network in the same environment running xp in bootcamp had no problems with the wireless network. I was not able to get any of the solutions on this page to work (I believe due to my ISP blocking other DNS servers).

Well, I updated to 10.5.8 last night and my wireless is now working in OSX. There is a reference in the release notes related to wireless:
“compatibility and reliability issues when joining AirPort networks”

So, give 10.5.8 a try - I am sure it won’t solve everyone’s problem, but you may get lucky. Maybe Ben can do some testing to see if there really is a fix.

Ben, I can’t thank you enough. Like others, a Google search found many forums on this problem but your solution is the only one that worked. My 20 mbps connection is now acting as it should. If only Apple would fix this issue with an update or in Snow Leopard.

Thanks again.
