Are you on 10.5.8?

 

[eckndu]

yes im on 8, is this a known issue?

I did the upgrade the second day it was out, and been using it since without any issue. this just started today.

(model is unibody mbp with the removable battery)

There has been a known issue with 10.5.8 and MBP's with wireless. However, it is said that it works/ works better with the power adapter plugged in.

If this is a real issue, this will not be the final Leopard update, as Apple cannot leave an OS with a known issue.

it suxs apple have to upgrade to bring us trouble.
i read some recent threads about wireless, ppl are having problems with slow internet or no connection at all. well mine can connect to the network, but it just wont get the assigned IP, Arrrr
I had to reset two routers to finally realize the problem is my mbp, the thing i trusted the most.

Could be the .8 problem. Try a new user and/or delete preferences.plist and com.apple.airport.preferences.plist.

omg, thanks iLog.Genius, that solved my problem. could you explain the reason behind this? it couldn't just be a simple file corruption?
