Wireless chip changed?
 

I recently had my N900 replaced under warranty by Nokia (due to the micro USB breaking as seems to be common)

I noticed that the new device has a significantly different MAC address for the Wireless LAN device than my previous N900.

The previous MAC began A8:7B:39: not surprising to see an A8 identifier in a device with an ARM A8 chip.

But the new device has a MAC address beginning 30:38:55:
Has there been a change in the chip used for wireless I wonder?

Anyone have any info on this?
Thanks

No. MAC addresses are assigned on a per-device basis and are not hard-coded into the chip. Both of those are assigned to Nokia, and the A8 in the first one was probably a complete coincidence.

And if the MAC changed the entire device was probably changed.

oh I know the device was changed, I have receipt saying so.

I had assumed (incorrectly it would seem) that the A8:7B:39 identifier was one Nokia and assigned to them for use with their A8 based devices, but as wmarone says just a coincidence.

I also couldnt find any reference the vendor ID for the new MAC, which made me curious.

I think the MAC address is stored in the config mtd partition (at least that's how it is on the N8x0s, retrieved by /mnt/initfs/usr/bin/wlan-cal and set via /sys/devices/platform/wlan-omap/cal_mac_address at boot time) so it's theoretically possible, however unlikely, that it's the same device flashed with a new config. It doesn't say anything about the chip in any case.
