I just posted details of my strange Linksys AM300 / Linksys WRT54GL DD-WRT / X-Net half-bridging issue where my router is in the 'Broadband' forum.  I thought I'd just post a link to it here to see if anyone else using X-Net is having the same issue.

I'd appreciate any ideas that anyone has on resolving this.

Please post replies in the 'Broadband' thread.

Thanks,

Sam.
