I Have a 2.4 GHz 17" MBP running 10.5.2 Problem: Recently each time I restart my MBP the wireless router restarts itself for no apparent reason, but it gets worst when the router has fully rebooted my MBP cannot find my wireless connection. Then I have switch off the Airport and manually restart the router. Then Switch the Airport ON and I am back online until I shut down or restart the MBP. if I put it to sleep no issues then. There are 2 other computers in the house 1 MB and a windows Laptop. MB running 10.5.2 has no issue and so does the PC. Here is what I have tried 1) Reset the router (Belkin N1) to factory default and downloaded the latest firmware. 2) Switching the Airport off before I shutdown or restart does not cause the above problem. This has been happening for almost 5 weeks just before and after 10.5.2 Can anyone help me with this.
