Hi

I installed Lion on our 3 year old Mac Book Pro laptop this week and ever since it has had real issues logging on to the wi fi at home and staying logged on.

It will log on eventually but no longer stays logged on for any length of time, offering only an odd message about 'timeouts' to explain why it won'y log on straight away.

Has anyone else experienced that or have any idea how to correct it?

There's a HUGE thread on Apple Support Forums about it. Personally I've been having issues with networking not coming up after a reboot on my MBP.

Thanks - glad I am not the only one.

I do hope, as an aside, that they do not stick to download only for the OS upgrades.

It took me over 7 hours to successfully download Lion! And a massive chunk of capped data into the bargain. And I had to download it twice - once on my Mac Pro workstation and once on the MBP. A CD would have been SO much easier.

Do yourself a favor and burn the Lion installer to a USB drive: http://support.apple.com/kb/DL1433

You can then use it to do clean installs.

All future updates will be deltas only.

Give these a go, the articles seem to suggest it is a problem with some routers as not all people who upgrade have problems. Hopefully one of the solutions works.

The USB recovery drive does not include the OS; it's still a download. If you want to make a full install drive then you need to use Disk Utility to restore InstallESD.dmg (found inside the installer .app from the App Store) onto the USB drive.

I have tried a couple of things that seem to have helped so far today at least!

1) I changed the Airport channel from 1 to 4

2) I deleted all the various stored wi fi networks which included all sorts of one-off connections in hotels and so on so that my home network was the only one on the list

So far today since then it has behaved normally.

I think this download and cloud thing is really going to be a problem for those who do not live in big cities.

I read in the UK papers that Virgin Media are pulling their internet service out of Westminster in London because they cannot upgrade the network cost effectively and at the moment can "only deliver 50mbps"!

I was browsing at 3.1 Mbps as I read that.....!! 

I do wonder whether iCloud will be remotely useful to anyone in the countryside. I only live 85kms from the capital of the nation and even that is too far away for ADSL 2 apparently.

Have you tried creating a whole new network profile in your Mac's network settings? Just to start from scratch.
