Internet slow

Hi all,

I've had my Macbook pro since two years and it's always been well behaved. However, in the past couple of days, the internet speed has been inconsistent to the point where it is now pretty much as slow as it could ever be. Web pages take minutes to load,

As well as the macbook, I have a iMac, Macbook air and iPhone and other all my apple devices on the same network still as fast as ever.

I have reset safari, crome browser, my apple internet modem,Airport extreme time capsule. restart computer. but still no luck.

even i have change my internet modem and time capsule.

by the way my macbook is working well with all application. i cannot see any application running slow.

also i have check with my internet provider from there side everything is well ok. even i don’t install any antivirus software on my mac.

my actual nework was like this.

i connect LAN wire from Modem to Time capsule from time capsule. and i have airport extreme i have extend my time capsule network on this it was working perfect. since two three days my airport extreme disconnect from time casual.

i am pretty much sure my macbook has some problem.

So I just wanted to ask, are there any causes for slow internet? Is there anything I can do?

Apple's Wireless Diagnostics may supply some additional helpful information. Run it on the MacBook exhibiting the trouble.

To use it, hold an option key while you click your Mac's Wi-Fi icon, and choose Open Wireless Diagnostics...

The following authentication dialog will appear:

Authenticate with your Admin password, then click the Continue button in the following:

The network analysis and diagnostic tests will take several minutes to complete:

When it completes, if your wireless network is functioning properly the following will result:

If something is amiss, supposedly the results will be different and you will be presented with helpful information.

Assuming your connection is "working as expected" select Continue to summary and click Continue:

Ignore the pre-populated text field, which is provided as a place for you to type in additional information should Apple ask for it in the course of obtaining technical assistance from them. Apple has no way of knowing where your router is located in your home, and certainly doesn't know if you even have an upstairs bedroom closet.

Click Continue.

The next step will also take a few minutes:

When it finishes, you will be presented with a summary that may or may not be useful to you. Let me know if it is.

The WirelessDiagnostics-xxx.tar.gz file deposited on your Desktop can be dragged to the Trash, or you may wish to expand it and examine its contents. It's up to you.

The diagnostic's Summary page is the one that might contain useful information:

If yours shows anything other than the above, follow its recommendations.

There really isn't very much of the WirelessDiagnostics report that is useful to anyone other than Apple's engineers. Most of its results are long, cryptic, and not worth posting.

Among the files it contains, the one titled wireless-diagnostics-xxxxxx.log file (where xxxxxx = random characters) is short enough to post in a reply, if you wish. Obscure or omit any information it contains that you consider personal.

The following is an example, which reveals nothing remarkable:

I'm having the same problem on my Mac Mini, while all other computers in the house are fine. But my Mac OS (on Mac Mini) is 10.7.5, not Sierra so I don't have the option to run the Wireless Diagnostics app. What can I do to fix it? Thank you.
