Only one (previously working) computer can't connect to the internet wired or wireless

Hello,
This one has me stumped! A 2008 iMac that has a wired connection to my router now won't connect to the internet, despite working earlier today. I've tried a different known good ethernet cable and I've tried a wireless connection on both bands with no luck. All other devices (5) on the network still connect with no problem wired or wirelessly. I first rebooted the router with no luck – iMac won't connect but other devices work fine.
This led me to believe this was either a software or hardware issue with this iMac. I ruled out a software problem by booting from an external drive with a fresh OS install on it, but it still won't connect either wired or wirelessly. I ruled out a hardware problem by connecting the iMac wirelessly to my cell phone running in wireless personal hotspot mode. The iMac then connected to the internet without issue.
I'm now thinking it's the router, but I'm unsure how to troubleshoot this as I don't know enough about this device and all the settings. Could there be a corrupted setting that's preventing this one computer from connecting on two different connections, or could this be something downstream being blocked at my ISP?
Any info would be appreciated.
Thanks.
