Unstable Wi Fi Snow Leopard
Posted 11 April 2012 - 08:09 PM
My Mac at work has become very unstable in it's Wi Fi connection.
It's an older Mac Pro running 10.6.8. Interestingly my father is having similar problems with his Macbook pro with same operating system at his house.
Many other machines and my iPhone connect to this network at work successfully. I've tried creating another network with my own Airport Express with similar results.
It is constantly forgetting the network and asking for the password, The connection strength is often quite variable but generally poor.
I have unsuccessfully tried;
Turning Airport off and on.
Creating a new location.
Renewing the DCHP lease.
Erasing and creating new keychains.
Deleting preference list com.apple.alf.plist
Often doing some or all of the above helps for 20mins or less before it goes haywire again.
Anybody got any thoughts or similar experience?

In system preferences, Network, Advanced where you can prioritise networks, I have deleted the network (with the ' - ' button) and then re-set it after a re-start.
Any and all of these things may or may not temporarily improve the situation but never for long and not always.

Using a static IP address has helped so far.
In System Pref>Network>Airport>Advanced>TCP/IP, I selected DHCP with manual address and specified the number it was already on and seems to be happy.
So what in effect did I do and could I have selected a higher (last) number?

Whilst using (old) Airport Extreme helped significantly, recently some similar issues started arising again. They were easier to rectify by turning off and then on airport on my mac but I was having to do it a few times per day.
Anyway I've now bought a pair of NetComm Powerline Adapters that transfer data through the power system.
They are brilliant! Connect one to your modem via ethernet cable supplied and plug in to the power. Connect another to your computer by the supplied ethernet cable and plug this one in. Wait 2 mins.
By some techno miracle, internet data passes through the power cables at speeds up to 200 Mbps.

I got mine from Officeworks. Shelf price was $149- but I had seen them cheaper on the net and so he brought them down to $94-.
The pack comes with two pre pared devices that work with all operating systems out of the box. If you want to modify the settings or possibly add more to your system you need a computer made by that other mob.
