MacBook Pro issue resolved totally now I hope

In a previous blog posting I mentioned the problems here and here, I was having with my 802.11n WPA2 encrypted network and a MacBook Pro.

In the end what seemed to help was ensuring that Airport was at the top of the network configurations.

However even with that it still took the MacBook Pro some time after sleep to re-connect to my 802.11n Airport wireless network. Even then sometimes it failed to re-connect so I had to turn the Airport on the MacBook Pro off and back on again.

The MacBook Pro has now been upgraded to Leopard 10.5.2 and this does seem to have resolved the issue fully, with the MacBook Pro re-connecting to the wireless network immediately rather than after a minute or so.

Hopefully it will remain resolved and not happen again.

MacBook Pro Airport issue resolved, possibly…

I think I may have resolved my MacBook Pro Airport re-connection issues.

I ensured that Airport is at the top of the network configurations and this seems to have solved my re-connection issue when running a pure 802.11n wireless network.

I find it strange that something as simple as moving a network configuration to the top should solve this issue with an 802.11n network. However it is not an issue when running in b/g compatible mode!

Well it’s working for me now.

MacBook Pro Airport Issues Continue…

Since I upgraded my Airport Extreme network to a pure WPA2 802.11n 5GHz wireless network, my MacBook Pro has consistently failed to re-connect to the network after waking from sleep.

It does this in both 10.4.10 and 11.5.1 and when connected to an Airport Express running 802.11g WPA/WPA2 no problems, will re-connect every time.

My iMac which is connected to the 802.11n network does not have this issue.

If I move back to 802.11n/b/g on the 2.4GHz radio mode the problem disppears.

I have followed the advice given by Apple here and another piece of advice which  said ensure the Airport is at the top of the network configurations, but alas no luck.

Once or twice the MacBook Pro has reconnected, but 99% of the time no re-connection and the only solution is to either join the 802.11g network or re-boot.

Annoying.

MacBook Pro Airport Sleep Issues

My MacBook Pro has stopped re-connecting to my Airport network after sleep. I am sure this is down to the fact that I have started to use it on a WPA2 802.11n wireless network.

Checked my settings, but nothing there that seemed out of order.

A quick Google search and up comes through this site the following Apple KB article which has a solution, will try it and see what happens.

802.11n

I was playing around with my new 802.11n Airport Extreme base station seeing how I could maximise the performance of the wireless network.

I switched to a pure 5Ghz 802.11n network and then using Chicken of the VNC on my work MacBook Pro made a connection to my iMac and set EyeTV going. I was quite impressed with the screen refresh, however it wasn’t good enough (even at 300Mbs) to watch remotely.

I also undertook some file transfers and was very impressed with the speed.

I had to switch back to b/g compatible mode which reduced the 802.11n speed down to 130Mbs, but as I have a fair few legacy devices I need the b/g compatability. I will at some point add an Airport Express or my older 802.11g Airport Extreme to one of the LAN ports of the newer base station to enable me to have a dual wireless network, one a pure 802.11n network and a b/g network.

The only problems I had were when I switched back to b/g compatible mode, I forgot to reset the security back to WPA/WPA2 mode which meant that my HP TC1100 Tablet failed to connect back onto the network. I had to reset the wireless security and then reboot the TC1100 before it would connect correctly to the wireless network. Other devices worked fine, butI suspect that was because theTC1100 hardware doesn’t support
WPA2.

I also had to delete and add back my wireless Canon MP600R wireless printer.

I am impressed with the new 802.11n Airport Extreme and I haven’t even started to utilise the full functionality of the device.
