Macbook Wireless Slow - 10.5.5 issue?

[rtrt]

Have a just over a year old Macbook - wireless has been fine - apart from the early performance issues many of us had.

Until recently where i thought it was slow. Wasn't sure if it was my imagination or maybe even some kind of interference.

Spec of Macbook below;
Model Name: MacBook
Model Identifier: MacBook2,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB
Memory: 1 GB
Bus Speed: 667 MHz
Boot ROM Version: MB21.00A5.B07
SMC Version: 1.17f0

Had a look on console to see if there was anything useful today and the events below look suspicious. Can anyone comment on whether these are a sign of any problem that I can deal with?

I'm in the UK - in case the reference above to NL which i take to mean Netherlands - is relevant

No problems with my wireless, but I do have those same four "Sound assertion" lines several times throughout my system.log. Maybe it's a 10.5.5 issue...

have just run the 10.5.5 combo updater and used Onyx to repair permissions, run maint scripts etc

will see how it goes

still interested in feedback from anyone else seeing/seen similar problems

update

Switched my MP to Wireless connectivity and had the router, Macbook and MP siting within 6 feet of each other.

Don't see the same issues with MP that I do with the Macbook. Makes me think there's something not right with the Macbook.

For example the events below are from the Macbook with nothing showing on the MP at that time.

Think the last 3 show why i experience very slow internet - the Wireless card or the Macbook itself goes into some kind of slow transmission mode.

There's no follow up message so far (1.5 hrs later) saying it's come out - and it is very slow right now.

The only thing i can think of is to reinstall Leopard. Any other thoughts?
