Which Router to work with Synology DiskStation DS212j NAS?

[!TIMMY!]

I am wanting to get a Synology DiskStation DS212j NAS in the future and was going to get a new Router at the same time, but my old Linksys is giving up the ghost so needing to buy a new Router now.

I mainly game on my PC and Xbox (wired), but also want to be able to stream iPlayer to the TV and radio to the digital radio so need a Router with good QoS to keep my ping down while others are on the internet doing stuff. We have Wireless N and G stuff to connect so would it be best to get a simultaneous dual band Router?

What would be your recommendations for a Router that's on the compatible list for the Synology DiskStation DS212j?

I have read the Billion 7800 is good, does not having 5GHz matter?

Oh, I am on Be 24mbps ADSL with fast path on.

Thanks for the reply. I've been looking at reviews of the 7800n and it looks good (well physically it doesn't but u know what I mean). Really want it but can't afford it with Xmas around the corner and I don't think I need it until I get the Diskstation which I also can't afford right now.
