Dropping connection with Leopard

[jamescwarren]

Hi, I am running Leopard 10.5.1 on my MacBook and ever since I installed it (as soon as it came out) my internet connection keeps dropping. It did not do this with Tiger. I know there's nothing wrong with my internet connection/router because my MacBook will stop dropping the connection as soon as I plug it into its MagSafe connector. I've tried booting up in Safe Mode and no joy. It gets really annoying because on things like MSN it keeps loggig in and out because of the connection. Safari repeatedly gives me the you are not connected to the internet warning. But plug it in and it's fine. Is there a fix for this? Anyone else having the same problem? Is it likely to be fixed in 10.5.2? Thanks.

I'm surprised you haven't seen the many threads in this forum devoted to this problem (do a search). I'm afraid there's quite a few people experiencing the same difficulties as yourself. For example I setup the following thread a couple of months ago that you could have a look at:

BUT before you do so (it's pretty damn long now) try the following:

1. Try a different encryption mode on your router such as WEP or even unsecured to see if it makes a difference.
2. Try different channel numbers for the router.

Failing that you could do what I did; delete all your current connections in the Network Preferences and then:

1. In Network Preferences click on the Airport section on the left.
2. Make sure Location is Automatic and "Ask to join new networks" is unselected.
3. Click the Advanced button.
4. Make sure your network is in the Preferred Networks table. And make sure when you created your network before that you selected "Remember this network".
5. Tick "Remember any network this computer has joined"
6. Untick the other two options.
7. In the TCP/IP section set "Configure IPv4" to "Manually".
8. Put in your local IP address for "IPv4 Address".
9. Put in the Subnet Mask from your Router's configuration web page. (Mine was 255.255.252.0).
10. Put in the IP address of your Router - again you can find this from your Router's configuration web page.
11. Set "Configure IPv6" to "Off".
12. In the DNS section remove all the DNS Servers and add the ones that again should be found in your Router's configuration web page. (For me it was 194.168.4.100 and 194.168.8.100).
13. Press OK and then press Apply.

A combination of the above three suggestions improved my connection (still no way as reliable or as fast as in Tiger / Windows though). If none of that works then check out the thread mentioned OR simply wait for 10.5.2 to come like a lot of us are currently doing and with our fingers crossed that it'll fix the problem!

Cheers.
