Quite frustrating having finally converted a client to Mac computers to then suddenly see their wireless network broken after upgrading the MacBook Pros to Leopard 10.5.7.
In short the MBP fails to connect with the hub (in this instance a BT Home Hub and BT Office Hub) when renewing the DHCP lease and thus reverts to using the internal value - 169.254.x.x. I have seen this problem before on my own networks and occasionally connecting an iPod Touch via WiFi. The solution would normally be to assign a static IP address on the local network for the network interface. But this time a static address did not work.
The solution is instead to change the security settings of the hub for the wireless network. I experienced this issue with the BT Home Hub and Windows Vista once so it is hardly unique to Mac OS X. But it is frustrating that these different platforms cannot standardise their protocols. For a brief moment my client feared they would have to roll back their OS with a clean install thanks to the inability of the BT Hub to communicate with OS X Leopard 10.5.7. I cannot recommend which wireless security to use, but the chances are setting a custom key (which should of course be changed regularly anyway) and choosing a different standard is as good a place as any to start in diagnosing your wireless connection issues.

Imagine surfing a tidal bore for 20km!
That is 12.5 miles for all us metric folk. And for all those west bank Severn surfers past and present that is like jumping into your car at Newnham, driving the A48 all the way to Over bridge and not stopping until you reach the curry houses on Bristol road…! That is a long way. Some pundits believe on the perfect tide the Severn horseshoe bend could be connected producing a ride in excess of 10 miles on the River Severn. But anything further than this really becomes the stuff of legends.
On the Araguari Pororoca it is a very different story… In fact this Spring, Sergio Laus, Pororoca pioneer and tidal bore emissary, has already breached the 10 mile mark. Unofficially. It has been an exceptional season for tidal bore surfers in Brazil with the wave reaching 15 feet in the wet months (February and March) and consistently reaching 8 feet through the drier months. Ideal conditions for distance surfing and Sergio clocked up a ride of approximately 16.5 km (10.3 miles) surfing for over 40 minutes. Just this Monday, Sergio put in a claim for a new distance surfing world record of 11.8km, exceeding his previous mark by 1.7km.
The dream mark is 20km - about 50 minutes constant surfing on the wave. That is 50 minutes on a wave travelling at around 15mph with the full power of the Atlantic tide behind. No mean feat! Sergio believes it is possible and 2010 might be the year…

My good friend Sergio Laus has once again broken the world record for distance surfing on the Araguari Pororoca in Amapa state Brazil. On Monday morning Sergio surfed the tidal bore a distance of 11.8km (7.4 miles) for 36 minutes. As with his previous world surfing record the ride was recorded with GPS and currently Sergio waits for official verification from the Guinness Book of Records.
This spring produced some of the largest Pororoca tidal bore's experienced in the last 15 years and in May Sergio clocked up his 50th ride on some of the largest tidal bores in the world.
And if you think surfing a wave for 36 minutes sounds like hard word, in February he surfed the Araguari Pororoca continuously for 45 minutes without official adjudication. An incredible distance on a very sizeable wave which probably pushes the world record beyond the reaches of what is attainable surfing on the River Severn tidal bore. That must take a lot of leg work!
Keep up to date with Sergio's adventures on his Pororoca surfing blog.
