SLOW internet on NEW MacBook Pro

stupid comcast has "Greyed" out my default comcast DNS server addresses such that I cannot delete them, so even when I add the openDNS dns servers in airport settings, they are below the comcast ones, and the comcast ones get used first and openDNS never works. How can I remove these!!?? I've tried everything, driving me insane! Damn Comcast :mad:

don't edit the setting on the airport software on your computer, add them to your ROUTER. Theres a DNS section I guarantee you. Its default is probably comcast servers or a setting that just says use default. You can FOR SURE change these settings. Personally I use a dual band linksys router with gigabit ethernet, i think its the top dollar linksys one but all the control panels are pretty similar.


Good luck!
 
On my westell 9100 router i cannot find where to add the opendns ip address', theres a DNS section, but i shows the devices that have connected to the router and they already have DNS servers added to them, wont let me change them

help!
 
Well, I don't have any experience with westell products, but if this helps, here's a picture of the main page of my linksys router settings. Currently I don't have any problems using default DNS settings (maybe its better here in MPLS than when i had problems with comcast in chicago) so I didn't change them, but the "static dns" fields are what you would want to edit.


So maybe check your DHCP settings section for it.

Ok.. I've seen a solution to this a while back so give it a shot....

for your DNS entry type your router address as the first entry and below that type the following 2 entries 4.2.2.1 and 4.2.2.2.

try that and see if it works... if that doesn't work just type 4.2.2.1 and 4.2.2.2

This Actually works!!!!!!!!

OMG THIS WORKED!!! Thank You so much! I've been dealing with the slowness forever!! Seriously, thanks so much for the help! such a little fix did so much!

Do you guys see the improvements just by having your router IP or also those weird 4.2.2.1... etc #s?

Don't rely on your perception. Use www.speedtest.net.

Those weird #'s are DNS (Domain Naming Service) server IPs. These particular IPs are owned by Verizon now. Although the speedtest is a good measure of throughput for your system, there is also slowdown due to inaccurate routing (which is not just a perceived slowdown). If your DNS server is routing inaccurately or not updated often enough, the hops ,may be excessive or down and this causes internet slowdown as the name is being resolved or located.

Speedtest doesn't always give a true indication as well, depending on the overhead on your system and if your ISP is throttling the throughput to Speedtest due to caps, bandwidth usage, etc (meaning that the same speedtest hosted by your ISP may yield higher results than Speedtest yields due to this overhead or throttling, and Speedtest doesn't always chose the closest or best server for measurements).
 
So are Verizon's DNS servers better than opendns, etc?

If my router is using the DNS servers from my ISP, what is the benefit of listing both my router and Verizon's DNS IPs?

If I m reading you right, the speed benefit then for these folks is noted when they switch from site to site, and not once they actually get to the site (which is what speedtest would show).

Yes, if this is helping, then their slowdown is getting to the site. When you type a url into the address bar it must use your DNS server to resolve it into the correct IP address and then navigate to that address. If your DNS is outdated it can take a while for the url to resolve to the correct IP. This would be a case where the internet would be slowed, as it would hang while resolving to the correct website. Most larger sites with hosted Static IPs don't have this problem, it is usually with the Dynamically hosted sites. The DNS will help to keep the routing current, so the least amount of hops are necessary and correct when a bad route has been shut down.

As for are Verizon's any better, that I couldn't say. I use my ISPs (Time Warner, as they have yielded good speed and accurate results for me) but used to use and prefer OpenDNS. I used Googles until I read that they are doing traffic tracking and refuse to feed their monster. The best DNS is the one that resolves the quickest with the most accurate and fastest routing.
 
How do I do the DNS settings thing? I'm a bit of a computer illiterate. lol
 
Network / Advanced / DNS / then add the DNS servers with the + buttons. (Make sure you have the right network selected on the left - wireless / wired, etc...)

I found the opendns #s to work best.... www.opendns.com (bottom right).

i am kinda confused on this DNS issue. am i suppose to input the DNS registered on my router to my airport settings? it has always worked fine with my old macbook before.

No - you don't have to. By default, it should look to your router for DNS (which is another whole story) which should be using your ISP defaults.

My guess with the folks having trouble is that the DNS is not working right with their routers, and so manually entering in the Verizon ones "fixed" the problem.

This being said, if your ISP has cruddy DNS servers, you can see speed increases by choosing something else other than the default, such as Verizon, OpenDNS, etc...
