release and renew ip?

Hey there, I was told to release and renew ip to fix a problem with my internet (some sites are not coming through)
So I went and found some instructions:
1. Close any open Internet applications (such as Web browsers and email). Be sure to save any changes to any open documents.
2. Choose System Preferences from the Apple menu.
3. Choose Network from the View menu.
4. Choose Active Network Ports from the Show menu.
etc etc

Except I can't find a "show" button in my network panel. Am I an idiot?

MacBook (black), Mac OS X (10.5.4)

Open System Preferences->Network
Select the network you are using (top item - says "connected") and then click Advanced at the bottom right.
Click "Renew DHCP Lease"
I am not sure this will solve your problem, but that's the button you are looking for.

Thanks. It didn't solve the problem though unfortunately. Would I need to restart the computer/router/internet or anything too?

Release and Renew solved the problem for my friend who is on Vista (the problem was caused by our internet provider.

unplug your modem (if you have one) and your router - plug in the modem and let it come up online and then plug in the router the router (it is better if you shut down your computer first and restart it last but usually that is not necessary in my experience)

*"some sites are not coming through"*

Sounds like a DNS issue to me, with which releasning/renewing your IP would most likely not have any effect.

Try flushing the DNS cache by opening the terminal app and typing: *dscacheutil -flushcache*

I didn't think it would help but now you know.
Are you using a proxy server?
Does this happen with all your browsers or only one?

Try this:
Run Network Utility.app (in Applications->Utilities folder) and select "Ping"
Enter the URL of one of the websites you can't access using the full URL
Example:
http://www.apple.com/startpage/
Then click "Ping" and see what happens.

You should get something like this;

Ping has started ...

PING http://www.apple.com/startpage/ (8.15.7.117): 56 data bytes
64 bytes from 8.15.7.117: icmp_seq=0 ttl=52 time=36.916 ms
64 bytes from 8.15.7.117: icmp_seq=1 ttl=52 time=36.579 ms
64 bytes from 8.15.7.117: icmp_seq=2 ttl=52 time=35.206 ms
64 bytes from 8.15.7.117: icmp_seq=3 ttl=52 time=34.917 ms
64 bytes from 8.15.7.117: icmp_seq=4 ttl=52 time=35.447 ms

--- http://www.apple.com/startpage/ ping statistics ---
5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max/stddev = 34.917/35.813/36.916/0.788 ms

If the Ping works, it's a browser issue.
If the Ping does not work, the address is being blocked by your ISP, a proxy or some other software on your system.

If your ISP is blocking you, you might try changing your DNS settings by following the instructions here:

No guarantee, but then there usually is not 🙂
