Mac OSX Lion problem - wifi connection drops after sleep

Mac OSX Lion problem – wifi connection drops after sleep

Updated – 18 April 2012 – Problem seems to have gone now, between my fix and the Apple update on 5 April.

Updated – 5 April 2012 – Apple released an update for iMac titled ‘iMac Wifi Update’ today, which I’ve now updated my system with. Hopefully this will completely fix the issue.

Original Post: Since upgrading to Lion (via App Store) I’ve had this issue on my iMac where wifi connection is always lost when come back from Sleep and have to reconnect – which didn’t happen in previous OSX versions. Annoying but the fact the workaround was simple meant I never looked into getting a fix, until today…

My fix was pretty simple – worked for me, maybe won’t work for everyones setup/situation:-

– System Prefs / Network / then Turn WiFi off
– Press Advanced button, it will probably show your usual WiFi network in Preferred Networks list
– Delete your usual WiFi network in this list (make sure you have your connection details/password first!!!)
– Press OK and will then need your System password to ok the change

After this, it then worked fine, auto-connecting after each Sleep.

So far tested with a short Sleep (2 mins) and a longer Sleep (about 30 mins)
Haven’t yet tested with an ‘overnight’ sleep.

I’ve added this info to Apple Support forum, as there seemed to be a lot of people with the same issue (20 pages worth!)

We’ve worked with Pat Walsh on a number of very different projects, from interactive video projects to mobile apps. His work is very thorough and has quickly become an essential and important phase of all the production work we do at Storythings. He’s thorough, diligent, and a pleasure to work with.

Pat came to Composed to respond to our (increasingly urgent) need of QA on mobile and web and I can testify he more than fulfilled the task. On the Android side, his very structured approach (first exploratory testing, then focus on defining test plans for a variety of scopes) and his clear knowledge of the latest mobile technologies have quickly paid off. He was involved directly with the developers (including myself) and this very dynamic relationship enabled us to annihilate bugs swiftly and efficiently.

Pat is an excellent one-stop-shop for testing Apps and Websites. He is a self-starter who just knows what needs to be done and gets on with it, and is responsive to requests for any specific testing requirements. He provides test plans and reports as a matter of course and was a pleasure to work with. I will definitely be working with Pat again if the opportunity arises.

Andrew Birley, PM, Storythings

Pat has been absolutely incredible at testing each of our projects he works on. He’s very professional, organised and diligent. I look forward to using him again in the future.

Pat Walsh fixed my site within hours of my contacting him – his WordPress website fix service clearly works!

Douglas Green, Douglas Software

Pat performs comprehensive website testing for us, across all the main browsers and platforms, including mobile devices. His flexible approach to testing and clear feedback enable us to have confidence that the business end of our website is still working smoothly after system updates and changes.

Steve Liu, Manager, Wicked Lasers

Couldn’t recommend Pat highly enough. He goes beyond what you’d expect of a QA tester, commenting more broadly on user experience and even design. He’s quick, efficient and thorough – couldn’t ask for any more.

Rob Calvert, Director, Click

We hired Pat to help with QA of a music streaming app. We needed someone with that magic “6th sense” of where the bugs are lurking; the ones which developers tend to miss. Pat more than fulfilled this need, with highly methodical approach and a great eye for detail.

Subsequently Pat has provided QA services for a personal app project of mine, finding a significant issue which had been lurking for some time.

Pat is a real asset to any team – highly competent technically but also easy going and a great guy to work with. Highly recommended!

Andrew Ebling, Head of App Development, Composed

Pat Walsh provided Kingston Valdes with a professional and personable service that was excellent value. The site was built and tested quickly, we are delighted with the results, and we have already had positive feedback from some of our clients. If you’re thinking of building a new site or adapting an existing one, I’d certainly recommend speaking with Pat about it.
