Q: Fast internet connection but web pages slow to load

I have a relatively fast internet connection: Download Speed - 60.5 Mbps; Upload Speed - 6 Mbps.

 

I get the same results on my MacBook Pro that runs on wifi, and my iMac that is directly connected to the ethernet. On the iMac, however, it is now taking forever for web pages to load.

 

I've read elsewhere that changing the DNS can eliminate some of these problems.  All of that is a little bit above my pay grade.

 

I know just enough to make me stupid, but I'm a good listener and I can follow directions pretty well.  Any help would be most appreciated!

 

Thanks,

KLOS

iMac, OS X El Capitan (10.11.3), 2.8 GHz; 8GB

    Hello KLOS,

     

    Thanks for using the Apple Support Communities!

     

    I understand that webpages are slow to load on your iMac but not on your MacBook Pro while they are connected to the same network. If you are using Safari, I suggest working through the following steps on your iMac to see if you can alleviate the slowness. 

     

    If Safari is slow, stops responding, quits unexpectedly, or has other issues - Apple Support

     

    Cheers!

    This does look like a DNS problem.

    Fear not, that is not hard.

    And to begin with, it may be useful to just compare what the settings are in your two macs - that may help us figure out what the problem is.

    So for now this is just a test, and will not change things.

     

    In System Preferences->Network, select the connection that is active on each mac, and click on "Advanced", then click on "DNS".

    On the left, under "DNS Servers:", what do you see in each mac?

    These are typically strings of numbers with periods, such as 8.8.8.8, or longer ones with colons; you don't need to worry about what they mean, just notice how different they are. Usually, these numbers are obtained automatically from your router, but they may also be entered with specific values.

    On the MacBook Pro (WiFi) the settings are 10.0.1.1

     

    On the iMac (Ethernet) the settings are 208.67.222.222 and 208.67.220.220

    Joe, I did disconnect the extension that was turned on. Unfortunately, it is a much-needed application.

    I did trash the plug-ins and that seemed to help a lot.  I guess my question is still - why on one (the iMac) and not the other (the MacBook Pro)?

     

    Thanks!

    This confirms my suspicion.

    Your MBP is getting the DNS from your ISP by setting the router as the DNS server.

    Your iMac has these specified DNS servers. Make a note of these 208.* addresses, just in case, and use the "-" button to delete them.

    See how things go.

    Just wanted you both to know that I'm still looking at this. (I generally can only work at it on the weekends.)

     

    Joe, removing the extension (Keeper Security) helps, but I need the app.

    Luis, I deleted the two settings and it populated two more: 209.18.47.61 and 209.18.47.62. Now, oddly enough, I can't delete them.

    If I switch the iMac over to wireless, I get the same setting as the MBP (10.0.1.1)

     

    I appreciate the support from both of you!

    Thanks.

    The fact that you get two dns server addresses and they appear greyed out and you can't delete them IS normal.

     

    These are given by your router and probably determined by your ISP. You can add other addresses, but as soon as you remove your custom addresses the default ones take over. Otherwise you might be left with no dns servers and would not be able to connect to anything (except by entering the IP numbers of any server, website, whatever...).

     

    Yoy may also try using 8.8.8.8, the google dns server, which tends to work well.
