I have a Seagate USB 3.0 hard drive that I formatted while connected to my rMBP. I selected the Mac OS Extended (Journaled) format and GUID. Seemed to work fine connected to the rMBP. Even ran a TM backup to it.

When I plugged the drive into the wireless router (Netgear R6250), I can see it from my rMBP and can read all of the files on it. However, I cannot write to the drive. I get an error message saying I don't have permission. Did I format it wrong? Is there a recommended format that I should use for a USB drive connected to the wireless router? Thanks!

Your Mac may be able to read and write the Mac format, but perhaps your router cannot. Try using FAT or FAT32.

I suggest as a network third party machine see if can accept Exfat instead of plain old FAT32.

Plus Netgear has an option on some of it's routers to act a Time Machine drive in their instructions How to setup Time Machine with your NETGEAR router.

Lastly you can read Netgear's R250/R6250 manual (on page 47 + 50) and see you have to setup permissions in the router setup. So read and follow that manual.

So if the router doesn't like HFS+ drives don't fret over using time Machine with it. To share a SMB network drive for time Machine see the blog post Configuring OS X Mountain Lion Time Machine to Work With CIFS (SMB) Share (don't worry because it works in 10.9.x too).

Well, alright - but I'm not the one having trouble, the OP is. I'm using an Airport Extreme Base Station with a Buffalo Linkstation Pro Duo NAS instead of a USB drive. Whole different setup, there.
